Abstract
The present invention discloses a kind of fixed contact arc striking piece, described arc striking piece is provided with striking groove, and on described arc striking piece, one end of striking groove is provided with boss, described arc striking piece is provided with arc striking piece installing hole; Be provided with laminating wall, arc striking piece is contacted closely with fixed contact, can absorb electric arc to greatest extent, be provided with striking groove, the effective electric current that guides makes high-temperature electric arc striking unimpeded, is provided with the transfer that boss is conducive to electric arc.
Description
Technical field
The present invention relates to circuit breaker, particularly relate to a kind of fixed contact arc striking piece.
Background technology
Circuit breaker is the electric current that can close, carry and cut-off under normal loop condition, and can close, the switching device of carrying and the electric current under cut-offfing abnormal loop condition (comprising short circuit condition) in official hour.The dynamic and static contact of circuit breaker is when disjunction short circuit current, often produce high-temperature electric arc, very harmful to circuit breaker of this high-temperature electric arc, the circuit breaker now commercially sold due to the structural design of arc-initiating device reasonable not, cause the dynamic and static contact of circuit breaker when disjunction short circuit current, the high-temperature electric arc four produced is penetrated, if can not be concentrated rapidly, and it is introduced in arc-control device fast extinguish, contact system will be burnt, the lighter seriously reduces the interrupting performance of circuit breaker, and severe one burns electrical equipment.
Summary of the invention
The invention provides a kind of fixed contact arc striking piece, by the improvement to arc striking piece structure, strengthen its striking performance, reach the object of protective circuit breaker and electrical equipment.
For reaching this object, the present invention by the following technical solutions:
A kind of fixed contact arc striking piece, described arc striking piece is provided with striking groove, on described arc striking piece, one end of striking groove is provided with boss, described arc striking piece is provided with arc striking piece installing hole.
Further, described striking groove is waist-shaped hole.
Further, described arc striking piece installing hole is screwed hole.
Further, described striking groove and described boss are arranged vertically.
Further, described boss is that the corrugated that arc striking piece is bent to form is protruding.
Further, arc striking piece is bent to form laminating wall away from one end of described arc striking piece installing hole.
Beneficial effect of the present invention is: be provided with laminating wall, arc striking piece is contacted closely with fixed contact, electric arc can be absorbed to greatest extent, be provided with striking groove, effective guiding electric current makes high-temperature electric arc striking unimpeded, is provided with the transfer that boss is conducive to electric arc.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is fixed contact arc striking piece perspective view.
Fig. 2 is fixed contact arc striking piece front view.
Fig. 3 be in Fig. 2 A-A to cutaway view.
In figure:
1, arc striking piece; 2, striking groove; 3, arc striking piece installing hole; 4, boss; 5, laminating wall.
Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
As shown in Figures 1 to 3, in the present embodiment, a kind of fixed contact arc striking piece of the present invention, arc striking piece 1 is provided with striking groove 2, described striking groove 2 is an elongated waist-shaped hole, striking groove 2 forms striking path thus effectively solves the smooth and striking problem slowly of high-temperature electric arc striking that the dynamic and static contact of circuit breaker produces when disjunction short circuit current, what on described arc striking piece 1, one end of striking groove 2 was vertical with described striking groove 2 is provided with boss 4, and described boss 4 is that the corrugated that arc striking piece 1 is bent to form is protruding; Described boss 4 can play the effect accelerating transferred arc; Described arc striking piece 1 is provided with screwed hole as arc striking piece installing hole 3, described arc striking piece 1 is fixedly connected on fixed contact by arc striking piece installing hole 3 and screw, and arc striking piece 1 is bent to form laminating wall 5 away from one end of described arc striking piece installing hole 3.
During work; arc striking piece 1 is arranged on fixed contact by arc striking piece installing hole 3 and screw; one end away from arc striking piece installing hole 3 is provided with the laminating wall to the turnover of fixed contact direction; arc striking piece 1 can be fitted tightly with fixed contact; arc striking piece 1 and fixed contact contact position are that the electric arc of fixed contact produces district, by arc striking piece 1, electric arc are reached boss 4 place, fast electric arc are delivered to arc-control device by boss 4; rely on arc-control device to carry out arc extinguishing, thus play the effect of protective circuit breaker and electrical equipment.
It is to be understood that; above-mentioned embodiment is only preferred embodiment of the present invention and institute's application technology principle; in technical scope disclosed in this invention, the change that any those skilled in the art of being familiar with easily expect or replacement, all should be encompassed in protection scope of the present invention.
