The utility model discloses have the plum blossom concurrently and touch the advantage that indicates to touch the finger with two self -reliances, simple structure, the size is little, and is with low costs, and the reliability is high. When high -voltage switch's moving contact when closing a floodgate, its effect of having played the direction, the possibility that in can making that the moving contact is accurate and inserting the static contact, avoided moving, the static contact bumps in high -speed motion, when onset of arcing because the resistant strong ability of electric arc of copper -tungsten alloy, can self with the drainage of electric arc elder generation, protect main contact and shield cover to exempt from by the electric arc scaling loss, make the high -voltage switch still can normal operating after the condition of electric arc production that opens and shuts.
Description
Technical field
A kind of for used for high-voltage switch in gas-insulated metal switchgear (abbreviation GIS) have striking function from
Vertical contact apparatus, have the ability of resistance to electric arc.Belong to high voltage electrical apparatus technical field.
Background technology
Striking contact one kind in existing GIS is using Mume flower contact structure.The shortcoming of this kind of structure is that part is many, knot
Structure is complicated, and assembling is complicated, and size is big.Radome material is copper, and head is welded with copper-tungsten part, high cost.
Additionally, also one kind is double self-support contact, such as Authorization Notice No. is the patent of CN201622941U：One kind is relied on oneself
Type contact, the shortcoming of this structure is that have gap between the contact finger piece of outside, and the metal particle producing during arc extinguishing can spray from gap,
Burn other parts of product, or product insulating properties can be made to reduce, electric field is bad；Another two fingertip is all copper,
Outside fingertip head is welded with copper tungsten head, high cost.
Content of the invention
Problem to be solved in the utility model is to provide a kind of structure simple, and size is little, low cost, the high tool of reliability
There are the self-support contact apparatus of striking function.
In order to solve the above problems, the technical scheme that the utility model provides is：A kind of self-support with striking function is touched
It is characterised in that including main fingertip, main fingertip is self-support fingertip to head device；It is provided with striking fingertip in the middle of main fingertip；Outside main fingertip
Side is provided with radome, and radome top is provided with copper tungsten shielding head.
Preferably, described main fingertip adopts copper self-support fingertip.
Preferably, described striking fingertip is self-support fingertip, and its end is petal-shaped.
Preferably, described, striking fingertip is welded with the copper self-support fingertip of copper tungsten head using head.
Preferably, described radome adopts aluminum radome.
Preferably, described copper tungsten shielding head passes through screw thread or screw is connected with radome.
Preferably, described striking contact is lower 0～3 millimeter than the shielding of copper tungsten.
The utility model has plum blossom fingertip and the advantage of double self-support fingertip concurrently, and compared with prior art, the utility model has
Have the following advantages：
1st, compare plum blossom fingertip, part is few, structure is simple, is easy to assembly and disassembly；
2nd, compare double self-support fingertips, be provided with striking contact, low cost in the middle of main fingertip, centering is good, when high-voltage switch gear
When closing a floodgate, it serves the effect of guiding to moving contact, moving contact can be made accurately to insert in static contact, it is to avoid dynamic and static
The possibility that contact collides in high-speed motion；When there being electric arc to occur, due to the strong ability of the resistance to electric arc of copper-tungsten, permissible
, by the drainage of electric arc elder generation, protection main contact and radome are exempted from by electrical arc erosion for itself, make high-voltage switch gear have electric arc to produce in folding
Remain to after situation normally run；
3rd, radome material is aluminum, and copper tungsten shielding head thread connects or is screwed on radome, is easy to make
Make, cost substantially reduces；
4th, appearance and size greatly reduces than Mume flower contact；Support oneself quite with double, but outer layer has radome；Thus like size
Under, fingertip between adjacent phase fingertip and fingertip to the dielectric strength between shell more preferably so that the reliability of high-voltage switch gear
Improve.

Specific embodiment
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in figures 1 to 6, a kind of structure of the self-support contact apparatus with striking function providing for the utility model is shown
It is intended to,, by main fingertip 1, radome 2, copper tungsten shielding 3, striking fingertip 4 forms for it.The screw thread dress by end for the striking contact 4
Enter the screw thread in the hole in the middle of main contact 2 to be fixedly connected；Radome 2 is connected and fixed by threaded interior hole and main fingertip 1 external screw thread
Together；Copper tungsten shielding 3 is fixed on radome 2 by 4 screws.
Striking fingertip 4 is self-support fingertip, is shaped as petal-shaped, and using copper, its head is welded with copper tungsten head.
Main fingertip 1 is self-support fingertip, and using copper, its head does not set copper tungsten head.
As shown in fig. 7, when high-voltage switch gear closes induced-current or the short circuit current of electric arc generation, now moving contact 6
Carry out closing operation, move to self-support contact direction, move to fast close to striking fingertip 4 when, prebreakdown, produce electric arc 5；So
Afterwards, when moving contact 6 is contacted with striking fingertip 4, after striking fingertip 4 is subject to the pressure of moving contact 6, diameter diminishes, and bears pressure, this
When arc energy and electric power born by striking fingertip 4, arc extinction；Moving contact 6 continues to move to self-support contact, with main fingertip
1 compression contact, both are gradually fully contacted, and now striking contact 4 is separated by a little gap with moving contact 6, striking
Fingertip 4 is recovered to reset condition by former compression position it is ensured that the performance of striking fingertip 4, when moving contact 6 moves to final position
When, high-voltage switch gear is in pass conjunction state.Because electric arc can produce drift during closing, the therefore head in radome 2 fills
There are copper tungsten shielding 3, guard shield cover 2 and main fingertip 1 not by flash burn.
When high-voltage switch gear cut-offs induced-current or the short circuit current having electric arc generation, now moving contact 6 carries out separating brake behaviour
Make, that is, with the direction motion closing a floodgate in opposite direction.Moving contact 6 is first separated with main fingertip 1, and now moving contact 6 and striking fingertip 4 connect
Touch；Moving contact 6 continues motion, when moving to abjection striking fingertip 4, produces electric arc 5, now arc energy and electric power are by striking
Fingertip 4 bears；When moving contact 6 moves to and leaves striking fingertip 4 certain distance, arc extinction；When moving contact 6 moves to finally
During position, high-voltage switch gear is in gate-dividing state.
