Abstract
The present invention relates to a single interrupted low-voltage switch device, in particular a current protection switch. In the switch device, when a short-circuit current (C) is interrupted, switch arcs (L, L') are formed. The switch device comprises two current back guides formed by a first conductor section (71) and a second conductor section (85). The short-circuit current (C) to be interrupted is respectively guided in the two conductor sections (71, 85) with the direction opposite to the direction of the current in the switch arcs. However, the second conductor section (85) only guides the short-circuit current (C) when the lowest point of the switch arc (L) is transitted to an arc guide rail (40) through a contact (20). After that, the two conductor sections (71, 85) repel the arc (L') together due to an electromagnetic force, thus the arc (L') is driven to an arc extinguish chamber (50) of the switch by a big force.

At this; This has decisive meaning; That is, when interruptive current, the switching arc that when the contact of cut-off switch (Kontaktstelle), produces is not retained on the contact of contact; But arrive as soon as possible in the arc control device of switch, this switching arc is through resolving into part electric arc and cool off and eliminating in these arc control device.
Therefore; Except contact and arc control device; Except two terminals, electric current connector be used for surveying the trip gear of the electric current that (Detektieren) guide at switch; Low voltage switchgear also has: electric arc guide rail (Lichtbogenleitschiene), and this electric arc guide rail is directed to arc control device with switching arc from the contact; And such device, that is, this device is supported the guiding of switching arc.
Background technology
In file DE19524915C2 He among the file DE3334852A1, the low voltage switchgear that starts mentioned type has been described.In these equipment; The arc blow-out winding (Blasschleife) that guides with the mode that centers on the contact is formed in first electric conductor; This first electric conductor is with the fixed contact (Festkontakt) of contact be connected with first terminals of switch (file DE19524915C2); Perhaps be formed in second electric conductor, this second electric conductor is with the movable contact (Kontakt) of contact be connected with second terminals (file DE3334852A1).Therefore, arc blow-out loop line (Blasschlaufe) is flowed through by electric current to be cut off, and produces arc blow-out magnetic field (Blasfeld).This arc blow-out magnetic field helps the selffield (Eigenfeld) of (unterst ü tzen) switching arc.Therefore, switching arc on its path from the contact to arc control device and additionally quickens.Thereby achieving shorter arc running time (Lichtbogenlaufzeit) and correspondingly improved arc performance
and enhance switch switching capacity
Summary of the invention
As given in claims; The objective of the invention is to; Realize the low voltage switchgear of the single interruption of the mentioned type of beginning, although simple structure, this low voltage switchgear is through short electric arc running time and good arc-extinguishing property and outstanding.
Low voltage switchgear according to single interruption of the present invention comprises:
First and second terminals,
Have fixed contact and the contact that has movable contact,
First electric conductor, this first electric conductor is connected first terminals with the mode of conduction with fixed contact,
Second electric conductor, this second electric conductor is connected with movable contact with mode second terminals of conduction,
With the mode first electric arc guide rail (Lichtbogenlaufschiene) that be connected of first electric conductor with conduction,
The second electric arc guide rail,
The 3rd electric conductor, the 3rd electric conductor is connected second electric conductor with the second electric arc guide rail, and
Be arranged in the arc control device between the first and second electric arc guide rails.
In this switchgear, when current interruptions, movable contact moves towards the second electric arc guide rail in the plane, and when breaking off in the contact, form be arranged in the plane, through the interval of the contact of separating definite switch distance (Schaltstrecke).In addition, the point (Fusspunkt) that descends most that remains on switching arc on the movable contact, that form when breaking off in the contact carries out the transition to from movable contact on the second electric arc guide rail, and electric current in this switching-over (kommutieren) in the 3rd electric conductor.
First electric conductor of this switchgear has and is parallel to that the plane stretches, that cross over (ü berbr ü ckenden) switch distance and the first conductor section away from the side edge of arc control device that be arranged in the switch distance.The 3rd electric conductor have be parallel to that the plane stretches, cross over the second conductor section of switch distance.During interrupt procedure, the not only first but also second conductor section and its ground in the opposite direction guide current in switching arc.
Therefore, replace near the arc blow-out winding of the costliness switch distance and two electric arc guide rails, low voltage switchgear according to the present invention has two electric currents that formed by the first and second conductor sections and returns and draw (Stromr ü ckf ü hrung).This electric current returns and draws simply that mode designs and require few space.Because the electric current to be interrupted in two conductor sections respectively with its guiding in switching arc in the opposite directionly, therefore two conductor sections repel (abstossen) switching arc jointly.Because the 3rd electric conductor and only after the most following of electric arc carries out the transition on the second electric arc guide rail, just guide electric current to be interrupted equally thus with the 3rd electric conductor all-in-one-piece second conductor section; Therefore from this king-sized electromagnetic force is provided constantly, this electromagnetic force will be based on the switching arc fast driving (treiben) on (fussen) two electric arc guide rails in arc control device.Because the second conductor section just participate in to make up electromagnetic force after only in will commutating the current to the 3rd electric conductor; Therefore this second conductor section can be arranged in the side edge away from arc control device of switch distance as the first conductor section, yet also can be arranged in the side edge towards arc control device of switch distance.Under any circumstance, low voltage switchgear according to the present invention is outstanding through simple structure, the arc duration of lacking and good arc extinguishing ability.
The first conductor section mainly (vorwiegend) is parallel to the switch distance and stretches, yet than the first conductor section, the second conductor section can have littler interval with respect to arc control device.In improved switchgear like this according to the present invention, switching arc can be eliminated especially fast and reliably.This mainly is; Because compare with the first conductor section; The second conductor section that more closely is positioned at the arc control device place affacts on the switching arc with bigger electromagnetic force in electric current switching-over back, and because so electric arc especially promptly is driven in the arc control device after it carries out the transition on the electric arc guide rail.
The second conductor section can be arranged to the relative first conductor section, to be used for the same crooked electric arc guide rail that stretches (this electric arc guide rail consumingly, typically with the direction of the switching arc of about 90 ° of changes between switch distance and arc control device) that utilizes switching arc is driven into arc control device apace.
When second electric conductor has when being parallel to the 3rd conductor section that the plane stretches (in the 3rd conductor section electric current before switching-over with its guiding in switching arc) in the opposite directionly, then can help carrying out the transition on the second electric arc guide rail based on the switching arc on the movable contact and can helping equally thus with to be interrupted commutating the current in the second conductor section.
In order to realize electromagnetic force (this electromagnetic force helps switching arc is carried out the transition on the second electric arc guide rail and helps equally thus to be cut off commutating the current to the second conductor section from movable contact); The first and the 3rd conductor section can be respectively to be arranged into the both sides on plane with respect to the spaced mode in plane; Wherein, the interval of the first conductor section is littler than the interval of the 3rd conductor section.
The 3rd conductor section can be configured to flexible and can production technology on favourable mode utilize a mode of its two ends to be placed on the end of drawing from the plane of contact bearing part of movable contact with conduction.The other end of the 3rd conductor section can be connected with the mode of bus (Stromanschluss) the second electric conductor all-in-one-piece coil with conduction with short circuit current release
.
When the second and the 3rd conductor section is arranged on the same side on plane with condition so; Promptly; Make and compare that the second conductor section has littler interval with respect to the plane, then can realize the effect that helps whole interrupt procedure of electromagnetic force with the 3rd conductor section.
In low voltage switchgear according to the present invention; Therein along order (der Reihe nach) layout first terminals, contact, the first and second electric arc guide rails, arc control device and second terminals successively; Second electric conductor can have the 4th conductor section that is arranged between second terminals and the arc control device; The 4th conductor section is perpendicular to the arc quenching plate orientation of arc control device; And in the 4th conductor section, electric current to be interrupted has the direction identical with switching arc (Richtungssinn) when switching arc flows in the arc control device.In such form of implementation, also help switching arc more consumingly and flow in the arc control device, and correspondingly additionally shorten arc duration.

When switch closure, movable contact 22 is supported on the fixed contact 21 under the situation that forms contact force.After this, the short circuit current C that indicates through arrow flow to terminals 60 from terminals 10 through electric conductor 70, fixed contact 21, movable contact 22, contact bearing part 24 and electric conductor 80.In order to interrupt short circuit current C, contact 20 is broken off, and swings around axis 23 counterclockwise in the E of plane at this contact bearing part 24 or movable contact 22.At this, under situation about forming based on switching arc L on two contacts 21,22, that be arranged in plane E, movable contact 22 separates with fixed contact 21.Equally, the switch that in Fig. 3, indicates is arranged in plane E equally apart from S.
As shown in Fig. 1 and 3, short circuit current C to be interrupted in two conductor sections 71 and 81 respectively with its guiding in switching arc L in the opposite directionly.Therefore, two conductor sections are owing to electromagnetic force is repelled switching arc L.Two conductor sections 71 and 81 are so arranged; Promptly; Make the component that on arc control device 50 directions, points to of electromagnetic force have enough sizes, with in order to ensure be positioned on the movable contact 22 the most following of switching arc carried out the transition on the electric arc guide rail 40 from contact 22 apace.
In order to utilize simple device to realize the component of size enough (dimensioniert), conductor section 71 is arranged on the side away from arc control device 50 of switch apart from S.Through be arranged in conductor section 81 on this side equally, just switch apart from S above, when interrupt procedure begins, realized repulsive interaction, being particularly conducive to of electromagnetic force carry out the transition to the component on the electric arc guide rail 40 with the most following of electric arc.
If conductor section 81 is arranged in switch apart from the S below; Promptly this conductor section 81 be positioned at switch apart from S on the side of arc control device 50; Then as from Fig. 2 and 3 conspicuous, than conductor section 71, conductor section 81 has bigger interval with respect to plane E.Realize equally in this case being enough big component for the transition of the most following of electric arc.
When conductor section 71 and 81 with plane E have the form of same intervals be positioned at perpendicular to plane E orientation and when passing among the Normal plane N that switch settles apart from S; And when the connection straight line G-that is directed to (guide current C's) conductor section 81 from (guide current C's) conductor section 71 in Normal plane N with respect to electric arc guide rail 30; 40 stretch--hold the most following of electric arc L-switch apart from the side edge of S away from arc control device 50, that is to say when above the switch distance, stretching, then realize applying the component of the effect that preceding text mention for certain.
Carry out the transition to 40 last times of electric arc guide rail on the most following of electric arc from movable contact 22, electric current C commutates in the electric conductor 80, and now from electric arc L ' through electric arc guide rail 40, electric conductor 84 and electric conductor 80 and be directed to terminals 60.In conductor section 85, short circuit current has like the identical direction of preceding text in conductor section 81.The electromagnetic force that plays repulsive interaction is created in two conductor sections 71 and 85 now.The switching arc L ' that this power will be based on two electric arc guide rails 30 and 40 is driven in the arc control device 50 of switch, and this switching arc L ' resolves into part electric arc
cooling through arc quenching plate 51 and eliminates in these arc control device 50.
Obviously, than conductor section 81, conductor section 85 has littler interval with respect to plane E.Therefore, the component of the driving switch electric arc L ' of electromagnetic force becomes big.Simultaneously, compare with conductor section 71, conductor section 85 be directed to arc control device 50 more nearby.Through this measure, help switching arc L to flow in the arc control device 50 especially effectively.
In order when interrupt procedure begins, to have produced enough big electromagnetic force, as seen in fig. 1, conductor section 71 mainly is parallel to switch and stretches apart from S.As seen in fig. 1; Switch mainly is parallel to arc quenching plate 51 apart from S and extends; And correspondingly, change about 90 ° of its direction apart from the electric arc guide rail between S and the arc control device 50 30,40 at switch; So advantageously, conductor section 85 is arranged to typically tilt about 30 to 60 ° with respect to the first conductor section 71 or arc quenching plate 51.After electric current switching-over, although 30,40 bendings of electric arc guide rail stretch, after this electric arc L ' and conductor section 85 are arranged to mainly parallel on sizable part of the travel path (Laufweg) of electric arc L '.
Be decomposed into part electric arc in order to help switching arc to flow in the arc control device 50 and with it; Electric conductor 80 has the conductor section 86 that is arranged between terminals 60 and the arc control device 50; This conductor section 86 is orientated perpendicular to arc quenching plate 51, and only has less interval with respect to arc control device 50.Short circuit current to be interrupted has in this section like the identical direction in switching arc L '.Therefore, short circuit current produces electromagnetic force in conductor section 86, this electromagnetic attracting force switching arc L or part electric arc, and the arc extinguishing ability of additionally improving switch like this.
