Abstract
The invention relates to a component structure of a low-voltage circuit breaker, in particular to an arc extinguishing system of a circuit breaker, which comprises a group of arc chutes arranged in multiple layers before the contact point of the circuit breaker, wherein the bottommost layer of the arc chutes is provided with an arc strike sheet; and the arc strike sheet comprises a horizontal base plate, an empty slot is formed in the base plate, and the front edge of the empty slot is provided with a length of upward-curving bent plate formed by the extension of the base plate. In the arc extinguishing system, the special structural style of the arc strike sheet can generate a magnetic field of which the configuration is different from that generated by the traditional arc strike sheet structure in the working process of the circuit breaker, the arc can be struck in a arc extinguishing chamber more quickly and be drawn upwards, and all the arc chutes are fully used for cutting the arc, so that the arc extinguishing effect is improved.
Description
Technical field
The present invention relates to the modular construction of low-voltage circuit breaker, specifically is a kind of arc extinguishing system of circuit breaker.
Background technology
Arc quenching system is a part of low-voltage circuit breaker indispensability when carrying out breaking current, and it generally includes arc control device that are positioned at breaker contact point the place ahead, and the multilayer arc extinguishing grid pieces is set in the arc control device, and the arc control device bottom is provided with the striking sheet.In the existing structure, the striking sheet is generally one flat plate, and in the circuit breaker course of work, the electric arc that the contact produces is drawn towards arc extinguishing grid pieces and is cut, extinguishes by arc extinguishing grid pieces under the effect in striking sheet magnetic field.This structure is when arc extinguishing, and electric arc concentrates on the arc extinguishing grid pieces place of bottom usually, can't make full use of whole arc extinguishing grid pieces and participate in arc extinguishing, thereby its arc quenching effect is not good.
Summary of the invention
Technical problem to be solved by this invention is that a kind of arc extinguishing system of circuit breaker that can improve arc quenching effect is provided.
Arc extinguishing system of circuit breaker of the present invention comprises the arc extinguishing grid pieces that one group of multilayer that is positioned at breaker contact point the place ahead is arranged, and is provided with the striking sheet at the bottom of arc extinguishing grid pieces; Described striking sheet includes the substrate of a level, has a dead slot in the substrate, is provided with one section by the extended bent plate that upwards bends up of substrate at the dead slot leading edge.
In the arc quenching system of the present invention, the special structure form of striking sheet can produce in the circuit breaker course of work and the different magnetic field configuration of traditional striking chip architecture, make electric arc can be introduced into arc control device more apace, and electric arc is upwards drawn, make full use of whole arc extinguishing grid pieces arc cuttings, improved arc quenching effect.Through actual verification, its quenching time and traditional striking chip architecture reduced in comparison can reach 30%.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the perspective view of striking sheet;
Fig. 3 is the perspective view of striking sheet.
Embodiment
As shown in Figure 1, this arc extinguishing system of circuit breaker comprises the arc extinguishing grid pieces 2 that one group of multilayer that is positioned at breaker contact point 3 the place aheads is arranged, and is provided with striking sheet 1 at the bottom of arc extinguishing grid pieces.As shown in Figure 2, the striking sheet includes the substrate of a level, has a dead slot 11 in the substrate, is provided with one section by the extended bent plate that upwards bends up 12 of substrate at the dead slot leading edge.
In the circuit breaker course of work, because the special the action of a magnetic field of striking sheet 1, the electric arc that produces between the contact 3 is introduced arc control device apace, and is upwards drawn, and is cut into segment by arc extinguishing grid pieces 2 and also finally extinguishes.
