Background technology
This type of heterogeneous derailing switch equipment is for example known from European patent document EP1149446B1.This type of derailing switch equipment has multiple breaker units.Between the first and second switch cylinder piece supports of breaker unit, arrange respectively a switch over travel.In known heterogeneous derailing switch equipment, breaker unit is located with respect to encapsulating housing by bearing insulation body.Bearing insulation body is used for keeping breaker unit on the one hand at this, and driving mechanism is also installed on the other hand in bearing insulation body.
In the electrodynamic situation that occurs short circuit current and associated, bearing insulation body is subject to the risk of very high fracture especially.Especially, for the size of accepting the bearing insulation body that switch machine provides must design to such an extent that correspondingly volume is larger, in therein, provide enough spaces to come for switch machine.Bearing insulation body must correspondingly be configured to solid (massiv), can resist the power being occurred.
Due to large volume and the solid construction of bearing insulation body, in the inside of encapsulating housing, produce the status requirement improving.In the time pursuing derailing switch device miniaturization, the bearing insulation body of this type of macrostructure is undesirable.
Summary of the invention
Therefore, technical problem to be solved by this invention is to provide a kind of heterogeneous derailing switch equipment, and described derailing switch equipment has the identical or improved mechanical strength of maintenance in the size of dwindling.
According to the present invention, this technical problem solves in the following way in the case of the heterogeneous derailing switch equipment of aforementioned type, makes at least one Cross slat against the first switch cylinder piece support in case side, thereby by fixed relative to one another switch cylinder piece support.
According to the present invention, heterogeneous derailing switch equipment preferably uses within the scope of middle pressure, high pressure and superhigh pressure.This voltage range arrives until hundreds thousand of volt from one kilovolt.For reducing the physical dimension of this type of heterogeneous derailing switch equipment, advantageously breaker unit is arranged in the encapsulating housing of Fluid Sealing.The encapsulating housing of Fluid Sealing can be with fluid filling, and described fluid advantageously has electrical insulation characteristics.For example can consider that insulating oil or insulation gas are as fluid.Especially, in the time using insulation gas, advantageously insulation gas is inserted under the pressure improving to the inside of encapsulating housing.Along with pressure raises, the electrical insulating property of insulation gas raises conventionally.As insulation gas, for example suitable is gas and the admixture of gas of nitrogen, sulphur hexafluoride or other electric insulation.At this, fluid should be applied in the pressure with several bar, and wherein the pressure in the inside of encapsulating housing should be higher than the pressure of the medium of encirclement encapsulating housing.With this, between the inside of encapsulating housing and the outside of encapsulating housing, provide pressure differential, wherein there is overvoltage in inside.
At this, advantageously make the breaker unit of multiple phases of electric energy transmission system be positioned at same fluid space.Therefore, can make the fluid of the inside that is positioned at encapsulating housing for the common electric insulation of multiple breaker units.
Breaker unit is attached troops to a unit respectively in a phase of heterogeneous electric energy transmission system, and for interrupting a phase of heterogeneous electric energy transmission system.Breaker unit is each has at least one position of the switch.The first and second switch cylinder piece supports of phase layout that is spaced from each other.Betwixt every region in there is the position of the switch.
Heterogeneous derailing switch equipment for example uses in so-called gas isolated switchgear.In this type of gas isolated switchgear, multiple electric switch devices in encapsulating housing, are arranged, such as circuit breaker, isolating switch, earthed switch, load disconnecting switch etc.Preferably, in the encapsulating housing of Fluid Sealing, also arranged the conductor piece for connecting valve device.The equipment that has formed encapsulation with this, described equipment is for example also suitable for use in inner space.Especially,, can form compact layout when under the pressure with in improving the inner space of fluid filling encapsulating housing.
But also can advise, make heterogeneous derailing switch equipment be configured to outdoor derailing switch.Encapsulating housing receives breaker unit, wherein carries out the connection of outdoor derailing switch in encapsulating housing outside by outdoor (Freiluft) wire.At this, heterogeneous derailing switch equipment can be configured to the so-called earthing of casing (Dead-Tank) or outer casing electrification (Live-Tank) equipment.Encapsulating housing self can be constructed by electric conducting material, electric conducting material is connected with earth potential, wherein, for making electrical connecting wire provide so-called outdoor via hole by these encapsulating housings, on its end, arrange tie point so that derailing switch equipment and outdoor wire electrically contact.Encapsulating housing also can be made up of electrical insulating material, and the tie point being wherein positioned at outside encapsulating housing is located immediately on encapsulating housing.
Breaker unit is the parts of electric switch device, for the manufacture of the circuit breaker position in switch over travel.For this reason, breaker unit is preferably around longitudinal axis orientation, and wherein, switch cylinder piece support is arranged on the opposed each end of breaker unit.Switch block support has limited the exterior contour of breaker unit.Preferably, switch cylinder device support is configured to columniform cylinder substantially, and described cylinder is mutually directed coaxially with its each cylinder axis.Cylinder axis defines the longitudinal axis of breaker unit.In the inside of switch cylinder piece support, for example arranged switch block, described switch block is used to form tie breaker position.Between the isolated first and second switch block supports of a phase, arrange switch over travel.The switch block of each switch block support of a phase can be movable relatively mutually at this, and making switch block is to form current path and mutually electric current contact and carry out current separation for form circuit breaker position in the scope of switch over travel.Relative motion is preferably carried out in the direction of longitudinal axis.Because switch block support has limited the housing profile of each breaker unit, thus in the inside of switch block support, provide spatial accommodation, to realize the mutual relative motion of switch block.At this, switch block is the mutual cylinder axis relative motion along switch cylinder piece support preferably.Spatial accommodation also can be used as flow control apparatus and is configured to control and guidance switching gas.Except switch block, switch block support also receives for transmitting motion to the parts on switch block.This base part is the part of so-called kinematic chain, and described kinematic chain is for moving to the transmission of switch block.At this, motion is preferably connected at least one switch cylinder piece support in front.Preferably, being connected in the front of removing from switch over travel carries out.
Region between two switch block supports can be for example by the sleeve bridge joint of electric insulation.The sleeve of this type of electric insulation can be for example the also insulating nozzle for control and guidance switching gas.It is directed rigidly on this insulating nozzle can be with respect to two switch block support angles.But insulating material sleeve pipe also supports movingly and for example as the part of kinematic chain, opens for example will move through switch over travel transmission.Addedly or alternatively, but also can advise making two switch block supports to interconnect by insulation pipeline section in the region of switch over travel, make to form switch container on breaker unit, described switch container respectively distolateral by switch block support limited boundary, wherein switch block support interconnects by insulated tube.The mutual relative motion of the switch block of breaker unit makes switch block support keep relatively static, makes by switch block support and provides the housing profile of the switch container of sealing by insulation pipeline section if desired.
Breaker unit should be stablized.By using Cross slat to realize, the mutually necessary breaker unit that interrupts heterogeneous electric energy transmission system is coupled to each other.The first switch block support is fixed to one another and mutually reinforces against having realized in case side on the first switch cylinder piece support.Cross slat interconnects the first switch block support.Cross slat and breaker unit are by being connected enduringly against point.Cross slat is for the horizontal force and moment of longitudinal axis transmission transverse to breaker unit.Preferably, Cross slat can be configured to extend point-blank.But also can make Cross slat be formed as particularly in end regions, having part bending, that curve-like arches upward.Using Cross slat to realize is assigned to the short-circuit force that has for example formed the power effect in different directions on different breaker units on different breaker units.In addition, the case side by Cross slat against, the structural volume of breaker unit is only amplified with very little degree.For the correspondingly size reduction of the necessary holding element of location breaker unit, because power can be distributed on the different holding element of greater number of different breaker units.
Can advise other favourable structure, make at least one Cross slat and the first and second switch cylinder piece supports are connected in relatively-stationary longitudinal bar angle each other rigidly.
By Cross slat is connected and has provided in addition following possibility with longitudinal bar, between the first switch block support, stablize and additionally also can be by the introducing of longitudinal bar realizable force or distribution, make additionally second switch piece support to be carried out to the connection of mechanically stable.Therefore, on the one hand can the first switch cylinder piece support is mutually stable, can, by breaker unit at the enterprising line stabilization of switch over travel, between the first and second switch block supports, stablize on the other hand.With this, more stable connection has been reinforced and provided to whole equipment in addition.
Can advise other favorable structure, make case side on the first switch cylinder piece support and the second switch cylinder piece support respectively against at least one Cross slat.
If each first and each second switch piece support at least one Cross slat is provided respectively, each switch block support each self is stablized and mutually support.Therefore, for example suppressed in the distortion of breaker unit between switch moving period or crooked.Except the electric power occurring, switching process is only followed with pure mechanical force, and described mechanical force is because the jumping characteristic motion of relatively large quality causes.Especially, on circuit breaker, use in the situation of Cross slat,, in the time that use is suitable for connecting rated current and connects the breaker unit of short circuit current, occurred that switch trembles.Can be by switch block support and therefore by breaker unit mutual orientation by Cross slat.
In addition, can advantageously advise making interconnective Cross slat and longitudinal bar to surround space completely.
Surrounded completely the Cross slat in space and longitudinally the connection tool of bar have the following advantages, the line of force can surrounding gap distributes and can introduce different in point.The quality that has realized the connection of longitudinal bar and Cross slat by the space between Cross slat and longitudinal bar reduces.By this type of space, can additionally support the rigidity of longitudinal bar and Cross slat.Advantageously, on this should the angle point in this type of space, make that odd number longitudinal carrier is relative with horizontal support to be shunk.Can touch by space on the breaker unit of derailing switch equipment, or monitor and observe described breaker unit.Can extend leakage path by space.In the region in space, the dielectric spacing between the part of guiding voltage becomes large.
Favourable structure in addition can advise making longitudinal bar is connected with Cross slat against between point on switch cylinder piece support.
Except arranging longitudinal bar, described longitudinal bar is congruently with switch cylinder piece support difference corresponding, be that described longitudinal bar has been stablized respectively the first and second switch block supports of strictly attaching troops to a unit in same phase, also can advise making longitudinal bar stably to affect different phases between the first and second switch cylinder piece supports.Longitudinally bar can angle on rigidly with Cross slat in being connected against putting into spacing on switch block support with Cross slat.
Favourable structure in addition can be advised that breaker unit is orientated and be positioned at a common plane, and on the both sides of this plane, be made Cross slat be resisted against on the switch block support of tubular.
Breaker unit and its switch cylinder piece support extend along a longitudinal axis respectively.Realize with the layout of these longitudinal axis in a common plane possibility that makes Cross slat be arranged in the both sides of this plane by being arranged in parallel of described longitudinal axis, thereby Cross slat fixing on switch block support is arranged on the both sides of this plane.The Cross slat being arranged on both sides is in compartment of terrain maintenance and fixed relative to one another by breaker unit.
Irrelevant with quantity, type and the structure of longitudinal bar and Cross slat, bar can have certain profile, be that bar can for example be provided as the hollow profile that is configured with rib, insulation position etc., can form antitorque as far as possible Cross slat or longitudinally bar or Cross slat and the longitudinally connection of bar at the least possible material and therefore using in a large number.
Advantageously, can advise in addition making Cross slat electric insulation works.
By the electric insulating effect of Cross slat, prevent short circuit or the bridge joint of the insulation stroke on electric switch device equipment.Therefore, for example, can realize out of phase breaker unit is interconnected, and also use if desired longitudinal bar gapping switch stroke.For this reason, can advantageously advise making Cross slat or longitudinally bar and by Cross slat and in the angle that longitudinally bar forms the connection of rigidity made by the material of electric insulation.For this reason, the material of the specially suitable other electric insulation that is glass fiber-reinforced plastics and for example epoxy resin, even if described material has high torsional rigidity and has for high pressure or also sufficient electric simulation strength of superhigh pressure under little quality.
Structure in addition can advantageously advise making breaker unit at least one be bearing on Cross slat.
Also can keep at least one breaker unit by Cross slat.Especially, in heterogeneous derailing switch equipment existing during more than two breaker units, while particularly there is three breaker units, can advantageously make only one or two breaker unit keep by supporting arrangement, and other (other is multiple) breaker unit is fixing by Cross slat (multiple Cross slat).Especially, in the time using three to be arranged in a breaker unit in plane, a breaker unit can be supported by the Cross slat being resisted against on two other breaker unit.
Favourable structure can advise making Cross slat to be only resisted against on switch cylinder piece support in addition.
If Cross slat is only fixed on switch cylinder piece support, Cross slat is mutually stable by corresponding switch block support.Do not need Cross slat to be fixed in addition on other assemblies.Therefore, avoided the requirement for the other structure space of heterogeneous derailing switch equipment.The breaker unit correspondingly keeping of heterogeneous derailing switch equipment is enough to support at this.Can between breaker unit, power be distributed to a great extent by Cross slat, make occurred short-circuit force or switch to be trembled and be distributed on wide basis.
Favourable structure in addition can advise making switch cylinder piece support to have respectively the interface electrically contacting for breaker unit.
Switch cylinder piece support at least limits respectively the exterior contour of resolving device unit, road on end.Advantageously, switch block support has electric guide rail, and the contact of interface on switch block support can be realized, and the mutual movable switch block that is positioned at switch block internal stent can be combined in to current path.For this reason, for example can advise making switch block support self to be configured to the form of for example cast body by electric conducting material.This has additional advantage, in switch cylinder piece internal stent, has formed the spatial accommodation of dielectric barrier, can arrange for example parts of arbitrary shape etc. almost of kinematic chain in described spatial accommodation.Use the interface for electrically contacting, the tie point of the fluid space outside that is for example positioned at encapsulating housing is connected conductively.

Embodiment
Fig. 1 shows the view with the heterogeneous derailing switch equipment of the first breaker unit 1, the second breaker unit 2 and the 3rd breaker unit 3.Three circuit breakers 1,2,3 are arranged in the inside of encapsulating housing 4 of Fluid Sealing.Encapsulating housing 4 is for example the housing of being made up of electric conducting material or the housing of being made up of electrical insulating material, and described housing has surrounded the circuit breaker 1,2,3 of heterogeneous derailing switch equipment.The inside of encapsulating housing 4 has fluid space, has arranged circuit breaker 1,2,3 in described fluid space electric insulation.The fluid space of encapsulating housing 4 is filled with the electric insulation gas under high pressure, preferably sulphur hexafluoride or nitrogen, for the insulation of circuit breaker 1,2,3 and other live part.Additionally improve the anti-breakdown strength of electrical insulation fluids by the fluid under the high pressure in the inside in encapsulating housing 4, thereby can reduce the mutual spacing of circuit breaker 1,2,3.With this, also can reduce the structural volume of encapsulating housing 4 and therefore reduce the volume of whole equipment.Circuit breaker 1,2,3 is configured to respectively same type, and is arranged in the same fluid space of encapsulating housing 4, and by same fluid around.
Describe according to the theory structure of the breaker unit of the first breaker unit 1 as example hereinafter.This structure is correspondingly also applicable to second and the 3rd circuit breaker 2,3.For better observability, omit the diagram of Cross slat and longitudinal bar at Fig. 1.
The first breaker unit 1 has the first switch cylinder piece support 5 and the second switch cylinder piece support 6.Two switch block supports 5,6 are respectively fitted with columniform case surface substantially, and two switch cylinder piece supports 5,6 are in a spaced-apart relation.Cylinder axis defines longitudinal axis.Two switch cylinder piece supports 5,6 have respectively therein by the spatial accommodation of switch block support 5,6 dielectric barriers.In this spatial accommodation, for example arrange switch block.In Fig. 1, symbolically illustrate switch block 7, described switch block 7 has represented the on-state of heterogeneous derailing switch equipment, this means that the switch over travel 8 between switch block support 5,6 passes through movable switch block 7 bridge joints.In switch over travel 8 example shown in Figure 1, form by the annular gap between two switch blocks 5,6.Can on demand switch over travel 8 be striden across and be surrounded by the pipeline section of electric insulation, described pipeline section by two switch cylinder piece supports 5,6 mutually towards end interconnect.
Two switch cylinder piece supports 5,6 have defined the external shell profile of the first breaker unit 1.By two switch block supports 5,6 mutually towards end can approach the spatial accommodation being defined by switch cylinder piece support 5,6.The end mutually deviating from of two switch cylinder piece supports 5,6 is sealed substantially, and wherein this sealing has the form that dielectric is favourable, for example, be formed as spherical caps.Switch block support 5,6 can also have special passage or control device with control and guidance switching gas therein.
For connecting the motion of movable switch block 7, on the end of that deviates from switch over travel 8 of the first switch cylinder piece support 5, provide space, by described space, the driving element 9 of the form at this with switch lever that can translational motion has been imported in the inside of the first switch cylinder piece support 5.Also can realize the motion being positioned on the inner switch block 7 of the first switch cylinder piece support 5 by driving element 9.This motion for example can be distributed and is also delivered in the spatial accommodation of the second switch cylinder piece support 6 by other actuated element, makes to transmit the motion of the switch block being surrounded at least in part by the first switch cylinder piece support 5 and/or second switch piece support 6.Therefore, for example can realize in the spatial accommodation that makes switch block move to the first switch block support 5 and in the spatial accommodation of second switch piece support 6, and can improve the contact separation of the switch block mutually can be movable relatively and the speed of the closing of contact.As the actuated element transmitting motion in the second switch cylinder piece support 6, suitable is electrical insulator.For example, can transmit motion with insulating material sleeve pipe, described insulating material sleeve pipe can surround switch block 7 and control the switching gas of breaker unit 1 inside.
Preferably, two casting matrixs that switch cylinder piece support 5,6 is configured to be made up of electric conducting material.On the surface of switch block support 5,6, arrange that interface 10a, 10b are with by heterogeneous derailing switch equipment access current path.In this case, interface 10a, 10b are configured to be threaded the contact-making surface of opening, in described screw thread openings, can screw bolt, make guide rail be fixed on interface 10a, 10b by cable termination or analog upper and can electrically contact.Guide rail can be suitable mode electric insulation ground by the insulating sleeve Fluid Sealing through encapsulating housing introduce.On the electric current guide rail (Stormbahnen) of spatial accommodation that is positioned at switch block support 5,6, can electrically contact the switch block of the inside that is positioned at the first breaker unit 1, make can realize by the first breaker unit 1 connection of current path between interface 10a, 10b.
For the switch block with circuit breaker position that structure can be movable relatively mutually, can advise using the group being formed by electric arc and the rated current switch block of relative motion mutually therebetween.By using electric arc and rated current switch block, make to protect rated current switch block not to be subject to high ablation.Suggestion for this reason, makes first to make arc switch piece and then make rated current switch block carry out electric current contact connecting Cheng Qian.In turn off process, first rated current switch block is separated and then separates arc switch piece.Ensure thus temporary impact (vor ü berschlag) or turn-offed electric arc to preferably occur between arc switch piece, made that rated current switch block is protected is not subject to high ablation.Can realize with this conductive capability of optimizing rated current switch block, and arc switch piece is set to the repellence high in particular for having of arcing.
In Fig. 2, in vertical view, illustrate the breaker unit 1,2,3 known from Fig. 1.At this, different from Fig. 1 is that switch over travel 8 is discharged by switch block, and in Fig. 2, breaker unit 1,2,3 is illustrated as in its scram position.Switch over travel 8 between switch cylinder piece support 5,6 does not have the switch block 7 of switch over travel 8 bridge joints of two switch cylinder piece supports 5,6.Switch block 7 is recovered in of two switch cylinder piece supports 5,6 and is positioned at the spatial accommodation of dielectric barrier at this place.As can be seen from Fig. 2, switch cylinder piece support 5,6 is uncovered in the scope of switch over travel 8.For improving the stability of each breaker unit 1,2,3, can advise making switch over travel 8 for example by the pipeline section bridge joint of electric insulation, described pipeline section is fixed on mutually point on switch block support 5,6 distolateral.Be not subject to outside mechanical influence with this protection switch stroke 8.In addition, also can have insulating material sleeve pipe in the region of switch over travel 8, described insulating material sleeve pipe can stride across switch over travel 8 in the state turning on and off electric insulation between two switch cylinder piece supports 5,6.
Now, Fig. 2 shows completing with the breaker unit 1,2,3 of the stable heterogeneous derailing switch equipment connecting.Described stable connection has the first Cross slat 11 and the second Cross slat 12.The first Cross slat 11 is connected the first switch cylinder piece support 5 of the first breaker unit 1, the second breaker unit 2 and the 3rd breaker unit 3.The second Cross slat 12 is connected the second switch cylinder piece support 6 of the first breaker unit 1, the second breaker unit 2 and the 3rd breaker unit 3.The main shaft of the first Cross slat 11 and the second Cross slat 12 extends at this longitudinal axis transverse to breaker unit 1,2,3.Main shaft extends on the shortest path between point 24 at two of Cross slat 11,12.Cross slat 11,12 is resisted against in each of the first and second switch cylinder piece supports 5,6 of breaker unit 1,2,3 at this.Against being undertaken by different fixing meanss.Therefore, Cross slat 11,12 can for example pass through spiral, riveted joint, bonding or other power coordinates and is connected rigidly with in breaker unit 1,2,3 angles with the Connection Element of form fit effect.By the mutual spacing of Cross slat 11,12 fixing breaker units 1,2,3.Spacing is chosen as at this electrical breakdown (Durchlag) that makes it possible to the electric insulating medium that prevents reliably for example insulating gas between breaker unit 1,2,3.Cross slat 11,12 is preferably configured to the Cross slat of electric insulation.Can advise making Cross slat 11,12 self preferably by the material of electric insulation for this reason, for example, be made by plastic composite etc.But also can advise making the part of Cross slat be configured to insulated part, make to prevent that current path from passing through between the first switch cylinder piece support 5 of breaker unit 1,2,3 and the second switch cylinder piece support 6.
