Abstract
The utility model discloses a device for arc striking, guiding, locating and stabilizing of an isolation switch. The device comprises two conductive arms which are arranged in parallel, a wiring base and an arc striking and stabilizing device which is fixed on the two conductive arms and the wiring base, wherein, the arc striking device comprises an arc striking bar, a connection board, a guiding groove, a locating plate and a stabilizing board, the connection board of the arc striking device which is arranged on the conductive arms and the arc striking bar is vertically fixed on the middle position of the connection board; the guiding groove of the arc striking, locating and stabilizing device on the wiring base is fixed on the wiring base; and the lower part of the guiding groove is provided with the locating board and the stabilizing board. The conductive position of the device is accurate, can avoid arc burning between a contact finger and a contact and realize the locating of the contact, and when a short circuit occurs in the circuit, the structure can guarantee the short-circuited current to stably and reliably go through the switch and avoid the opening of the circuit.
Description
Technical field
The utility model relates to a kind of heavy current disconnecting switches, particularly a kind of striking positioning stablity device of big moving, thermally-stabilised isolating switch.
Background technology
At present, isolating switch on the market minute, when closing a floodgate, fingertip just directly contacts with contact elements, this situation is when isolating switch branch, combined floodgate, the little electric arc that the residual current of circuit, inductive current, capacitance current produce just directly burns contact and fingertip, causes the contact fingertip to burn out.When short circuit appears in circuit,, electrodynamic effect burns out isolating switch owing to can making the isolating switch separating brake produce big electric arc.
Summary of the invention
The utility model relates to a kind of isolating switch of protecting and is not burnt, the reliable striking stabilizing arrangement of isolating switch conduction contact stabilization when reaching short circuit.
In order to solve above technical problem, the striking of a kind of isolating switch of the present utility model, guiding, location, stabilizing arrangement, comprise conductive arm, the junction block of two parallel devices and be separately fixed at striking stabilizing arrangement on two conductive arms and the junction block, described arc-initiating device comprises starting rod, connecting plate, gathering sill, location-plate and steadying plate, the described connecting plate that is located at the arc-initiating device on the conductive arm is fixed between two conductive arms, at the center of connecting plate vertical fixing starting rod; The gathering sill of the striking positioning stablity device on the described junction block is fixed on the junction block, is provided with location-plate, steadying plate in the bottom of gathering sill.
Location-plate and steadying plate have been installed in the lower end of described gathering sill.
The advantage of above structure is: 1. guide effect: when conductive arm was downward, the gathering sill of this device can guide starting rod downward, guaranteed the accuracy of conductive site; 2. striking effect: when switch separating brake or combined floodgate, starting rod on this device conductive arm contacts with gathering sill elder generation on the junction block, contact behind the contact on the fingertip of junction block and the conductive arm, electric arc can only burn starting rod and gathering sill, has protected that no electric arc burns between fingertip and contact; 3. positioning action: when contact moves down, move to certain position, the starting rod of arc-initiating device just in time touches location-plate, stops it to continue to move down, thereby realizes the positioning action to contact; 4 good stabilities: when line short, this structure can guarantee that switch reliablely and stablely by short circuit current, the separating brake phenomenon can not occur.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the partial structurtes schematic diagram of the utility model gathering sill (6).
Embodiment
As shown in Figures 1 to 3, at the fixing connecting plate 4 of arc-initiating device of the front end of the conductive arm 1,2 of two parallel devices, at the center of connecting plate 4 vertical fixing starting rod 5, the gathering sill 6 of described arc-initiating device is fixed on the junction block 3, gathering sill 6 inboards below horizontal location-plate 8, fixation one fixing-stable plate 7 above the location-plate 8 in its outside.
During work, under the effect of external force, conductive arm 1,2 moves down, and starting rod 5 is limited in the gathering sill 6 and moves down simultaneously, has guaranteed the accuracy rate that fingertip contacts with contact; When conductive arm 1,2 continued to move down, starting rod 5 touched location-plate 8, can not move the position that restriction conductive arm 1,2 moves down downwards again; When conductive arm 1,2 can not move down again, because operating mechanism do not put in place, still continue action, move make the direction of motion changed course of conductive arm 1,2 by four connecting rod effects before, at this moment, starting rod 5 just in time inserts in the hole of location- plate 8 and 7 of steadying plates and fixes; Effect stable when guaranteeing switch by short circuit current is also played in like this, not only striking, guiding, location.
