Abstract
The invention discloses a static contact arc-striking piece. An arc-striking groove is formed in the arc-striking piece; a boss is formed at one end of the arc-striking groove in the arc-striking piece; an arc-striking piece installation hole is formed in the arc-striking piece; a joint wall is formed so that the arc-striking piece can be contacted with a static contact closely, and an electric arc can be absorbed to the maximum; the arc-striking groove is formed, so that a current is led effectively to enable the arc-striking of a high-temperature electric arc to be unimpeded; and the arrangement of the boss is favorable to the transfer of the electric arc.
Description
Technical field
The present invention relates to circuit breaker, relate in particular to a kind of fixed contact striking sheet.
Background technology
Circuit breaker is can close to close, carry and cut-off the electric current under the normal loop condition, and can close the switching device that closes, in official hour, carries and cut-off the electric current under the unusual loop condition (comprising short circuit condition).The dynamic and static contact of circuit breaker tends to produce high-temperature electric arc when the disjunction short circuit current, this high-temperature electric arc is very harmful to circuit breaker; The circuit breaker product of selling on the market now is because the structural design of arc-initiating device is reasonable inadequately; The dynamic and static contact that has caused circuit breaker is when the disjunction short circuit current, and the high-temperature electric arc four that is produced is penetrated, if can not apace it be concentrated; And it is introduced in the arc-control device fast extinguish; Will burn contact system, the lighter seriously reduces the interrupting performance of circuit breaker, and weight person burns electrical equipment.
Summary of the invention
The present invention provides a kind of fixed contact striking sheet, through the improvement to the striking chip architecture, strengthens its striking performance, reaches the purpose of protective circuit breaker and electrical equipment.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of fixed contact striking sheet, said striking sheet is provided with the striking groove, and an end of striking groove is provided with boss on the said striking sheet, and said striking sheet is provided with striking sheet installing hole.
Further, said striking groove is a waist-shaped hole.
Further, said striking sheet installing hole is a screwed hole.
Further, said striking groove is arranged with said boss is vertical.
Further, said boss is protruding for the corrugated that the striking sheet is bent to form.
Further, the end away from said striking sheet installing hole is bent to form the applying wall on the striking sheet.
Beneficial effect of the present invention is: be provided with the applying wall; The striking sheet can be contacted with fixed contact closely, can absorb electric arc to greatest extent, be provided with the striking groove; The effective guidance electric current makes that the high-temperature electric arc striking is unimpeded, is provided with the transfer that boss helps electric arc.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is a fixed contact striking sheet perspective view.
Fig. 2 is a fixed contact striking sheet front view.
Fig. 3 be among Fig. 2 A-A to cutaway view.
Among the figure:
1, striking sheet; 2, striking groove; 3, striking sheet installing hole; 4, boss; 5, applying wall.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Shown in Fig. 1～3; In present embodiment; A kind of fixed contact striking sheet of the present invention; Striking sheet 1 is provided with striking groove 2, said striking groove 2 is an elongated waist-shaped hole, has effectively solved the smooth and striking of high-temperature electric arc striking that the dynamic and static contact of circuit breaker produced problem slowly thereby striking groove 2 constitutes the striking paths when the disjunction short circuit current; An end of striking groove 2 and said striking groove 2 are vertical on the said striking sheet 1 is provided with boss 4, and the corrugated that said boss 4 is bent to form for striking sheet 1 is protruding; Said boss 4 can play the effect of quickening transferred arc; Said striking sheet 1 is provided with screwed hole as striking sheet installing hole 3, and said striking sheet 1 is connected on the fixed contact through striking sheet installing hole 3 and screw, and the end away from said striking sheet installing hole 3 on striking sheet 1 is bent to form applying wall 5.
During work, striking sheet 1 is installed on the fixed contact through striking sheet installing hole 3 and screw, is provided with the applying wall to the turnover of fixed contact direction away from an end of striking sheet installing hole 3; Striking sheet 1 can be fitted tightly with fixed contact; Striking sheet 1 is the electric arc generation district of fixed contact with the fixed contact contact position, through striking sheet 1 electric arc is reached boss 4 places, fast electric arc is delivered to arc-control device through boss 4; Rely on arc-control device to carry out arc extinguishing, thereby play the effect of protective circuit breaker and electrical equipment.
What need statement is; Above-mentioned embodiment only is preferred embodiment of the present invention and institute's application technology principle; In the disclosed technical scope of the present invention, any variation that the technical staff expected easily or replacement of being familiar with the present technique field all should be encompassed in protection scope of the present invention.
