Description
Technical field
The utility model relates to a kind of circuit breaker, particularly relates to the improved circuit breaker of a kind of striking sheet.
Background technology
The dynamic and static contact of circuit breaker is when the disjunction short circuit current, tend to produce high-temperature electric arc, this high-temperature electric arc is bigger to the harm of circuit breaker, if can not apace it be concentrated, and introduce arc extinguishing in the arc control device apace, high-temperature electric arc will be burnt contact system, and the lighter can seriously reduce the interrupting performance of circuit breaker, and weight person will burn electrical equipment.In order to address this problem, the circuit breaker of prior art, be that a striking sheet is installed between arc control device and fixed contact, the structure of this striking sheet as shown in Figure 1, this striking sheet 1 ' be provided with place bending, and by this place bending forms flat sheet 11 ' with bending sheet 12 ', this striking sheet 1 ' by bending sheet 12 ' be connected with fixed contact, flat sheet 11 ' part is used for realizing striking, because this striking sheet 1 ' flat sheet 11 ' be straightened condition, the oval aperture place distance of itself and the undermost arc quenching plate of arc control device is far away, has caused the smooth and unhappy problem of striking of striking.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, provide a kind of striking sheet improved circuit breaker, by the improvement to the striking chip architecture, the high-temperature electric arc that is produced in the time of can apace dynamic and static contact being separated is concentrated, and guides, delivers to arc control device fast and carry out arc extinguishing.
The technical scheme that its technical problem that solves the utility model adopts is: the improved circuit breaker of a kind of striking sheet comprises base, fixed contact, striking sheet and arc control device; These arc control device are made of a plurality of arc quenching plates that are installed on the base by support, are respectively equipped with a U type open slot on each arc quenching plate, are respectively equipped with an oval aperture in the inboard of each U type open slot; This fixed contact be installed in the corresponding base of arc control device on; This striking sheet has the bending of two places and forms the first bending sheet and the second bending sheet by this two places bending; This first bending sheet bends downwards, and this second bending sheet is bending upwards; This striking sheet is connected with fixed contact by the first bending sheet, and the end of the second bending sheet of this striking sheet is near the oval aperture place of a undermost arc quenching plate in the arc control device.
The length dimension of the described second bending sheet is greater than the length dimension of the first bending sheet.
The second bending sheet of described striking sheet is upwards along an angle of inclination bending.
The bending angle of the described second bending sheet is 82 °～84 °.
The beneficial effects of the utility model are owing to adopted the striking sheet to be arranged to the bending of two places and to be formed the first bending sheet and the second bending sheet by this two places bending; And this first bending sheet bends downwards, and this second bending sheet is bending upwards; This striking sheet is connected with fixed contact by the first bending sheet, and the end of the second bending sheet of this striking sheet is near the oval aperture place of a undermost arc quenching plate in the arc control device.This structure has made full use of the second bending sheet of striking sheet and has tilted upward, and makes the more close arc control device of arc ignition portion of striking sheet, and the high-temperature electric arc that is produced in the time of can apace dynamic and static contact being separated is concentrated, and guides, delivers to arc control device fast and carry out arc extinguishing; Thereby solved the not smooth and unhappy problem of striking of high-temperature electric arc striking that circuit breaker is produced effectively when breaking current.
Below in conjunction with drawings and Examples the utility model is described in further detail; But the improved circuit breaker of a kind of striking sheet of the present utility model is not limited to embodiment.
