Abstract
The utility model relates to a moulded case circuit breaker, in particular to a dual flicking type moulded case circuit breaker. The moulded case circuit breaker adopts the technical scheme that an arc striking sheet is fixedly arranged on a static conductive piece and comprises an arc striking sheet body and a supporting foot; the arc striking sheet body is integrated with the supporting foot; an open groove is formed on one side of the arc striking sheet body; the arc striking sheet is fixedly arranged on the static conductive piece via the supporting foot; the arc striking sheet body is located between lateral plates of an arc extinguishing device, and the arrangement direction of the arc striking sheet body is basically the same with that of grid chips of the arc extinguishing device; and the open groove on the arc striking sheet body faces to the static contact. By adopting the arc striking angle technology, the arc striking sheet is electrically connected with the static contact of a dual flicking type contact system, so that the burning loss of the dynamic contact of the moulded case circuit breaker in the dual flicking type contact system is reduced during the disjunction of short circuit current.
Description
Technical field
The utility model relates to a kind of breaker of plastic casing, particularly twoly scolds the open form breaker of plastic casing.
Background technology
For a long time, the arc leading angle of the arc-control device in the circuit breaker applies in the plate contact system or U type contact system of breaker of plastic casing always, scolds several nothings of open form circuit breaker to use for two.Two contact systems of scolding out breaker of plastic casing produce electric arc and cause scaling loss serious when the disjunction short circuit current, have influenced the use that is flexible coupling in known arc leading angle technical scheme, and can cause is flexible coupling blows.
Summary of the invention
The utility model overcomes the defective that prior art exists; Arc leading angle technology in a kind of utilization is provided; Make it and two fixed contact of scolding the open form contact system between forms and is electrically connected, twoly scold novel pair of the scaling loss situation of open form contact system breaker of plastic casing fixed contact when the disjunction short circuit current to scold the open form breaker of plastic casing thereby reduced to use.
Realize above-mentioned purpose, the utility model adopts following technical scheme: scold the open form breaker of plastic casing for a kind of pair, include housing, be located at operating grip, static contact head device, trigger device, arc-control device and tripping mechanism in the housing; Wherein static contact head device includes quiet conducting strip, fixed contact and fixed contact; Described fixed contact places in the arc control device of arc-control device, it is characterized in that: be set with the striking sheet on the said quiet conducting strip, said striking sheet comprises body and feet; Body and feet are wholely set; One side of body offers open slot, and said striking sheet is fixedly installed on the quiet conducting strip through feet, and the body of said striking sheet is between the side plate of arc-control device; And it is basic identical that its grid sheet that direction and arc-control device are set is provided with direction, and the open slot on the body is towards the fixed contact setting.
Through taking such scheme, when passing through short circuit current in the circuit, fixed contact moves downward under the effect of electrodynamic repulsion force; Because the existence of striking sheet; Make electric arc turn to rapidly on the striking sheet, reduced the ablation time of electric arc on fixed contact, protect fixed contact effectively; And then get in the arc control device of arc-control device, and the having to be beneficial to and strengthen the suffered magnetic blow-out power to that side of arc control device of electric arc of the dual-side of striking sheet open slot.
Further being set to of the utility model: said striking sheet is cut apart a connecting piece at the middle part of one of which side to the metallic plate center by a rectangular metal plate; Being bent into feet to brace again constitutes; The brace bending back that said striking sheet one side is cut apart constitutes striking sheet one open slot; The grid sheet of the body of said striking sheet and arc-control device laterally arranges, and the distance between the grid sheet of said striking sheet body and adjacent arc-control device is smaller or equal to the distance between the grid sheet in the arc-control device.
Through the above-mentioned further plan of establishment, make the processing of striking sheet convenient, the position of above-mentioned in addition striking sheet setting is to guarantee not contact the striking better effects if between the interior parts of striking sheet and arc-control device.
Further being provided with again of the utility model is: the feet riveted joint of described striking sheet is arranged on the quiet conducting strip, and said fixed contact is under the repulsion effect, and fixed contact can place in the open slot of striking sheet.
Through the further plan of establishment, riveted joint can prevent to be flexible coupling and blown, in addition and more firm between the quiet conducting strip.
Below in conjunction with accompanying drawing the utility model is done further explain.
