Abstract
The utility model provides a conventional circuit -breaker with separate arc structure, separates the arc piece through setting up in lower casing bottom, separates the fixed slot fixed mounting that the arc piece passes through inferior valve body bottom, separates arc piece looks interval arc through this structure, assurance safety, and this structure is firm is difficult for the landing.
Description
Technical field
The utility model relates to field of circuit breakers, is specifically related to a kind of omnipotent breaker with arc structure.
Background technology
Universal circuit breaker function introduction: circuit breaker is three-dimensional arrangement form, contact system, momentary excess current release left side plate are installed on one piece of insulation board.Arc quenching system is equipped with on top, and operating mechanism can be contained in dead ahead or right flank, has " dividing ", " conjunction " instruction and manual dectiergization button.Shunt release is equipped with on its upper left side, and the under-voltage release be connected with semiaxis of threading off is equipped with at back.Quick-magnetic saturated current transformer or current-to-voltage converter are enclosed within Down Highway, the arc poor effect between existing universal circuit breaker contact.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present utility modelly provide a kind of omnipotent breaker with arc structure.
The technical solution that the utility model adopts is: a kind of omnipotent breaker with arc structure, comprise housing, described housing comprises upper shell and lower house, conductive mechanism and operating mechanism is provided with in described housing, described housing bottom is also plugged with some conductive bus bars, by electrical connection on-board the circuit breaker, described lower house back is also provided with some arc sheets to described conductive bus bar, and described arc sheet is between laterally adjacent conductive bus bar.
Be provided with holddown groove bottom described lower house, described arc sheet is fixed in holddown groove.
Described arc sheet is provided with snap fit, is provided with hook groove in described holddown groove, and described arc sheet and holddown groove are by snap fit and hook groove snap-fit engagement.
Described lower house is also provided with some installing holes, and described upper shell is arranged on installing hole internal fixtion with lower house by screw and is connected.
The beneficial effects of the utility model are: the utility model provides a kind of omnipotent breaker with arc structure, by arranging arc sheet bottom lower house, arc sheet is by the holddown groove fixed installation bottom lower house, by the alternate arc of this structure arc sheet, ensure safety, and the firm not easily landing of this structure.
