Abstract

The invention belongs to low voltage electric equipment, it relates to a rotating axes structure of breaker, specially a breaker rotating axes part which can avoid arc. It includes a rotating axes base, acting contactor is mounted in the cavum of the rotating axes base, the rotating arm of the acting contactor can rotate around the center of the base, the fore end of the rotating arm is throw out from the rotating axes base, and set with contacting point which matches with statistic contactor, flame-retarded insulated board is set in inner side of the rotating arm, the main body of the flame-retarded insulated board is arc surface, it can slide along the outer surface of column of rotating axes base with the rotation of rotating arm. The invention can avoid the arc enter rotating axes effectively, and the structure is simple, production is convenient.

Description

The breaker rotating axis component of preventing electric arc form back burning
Technical field
The invention belongs to low voltage electrical equipment, relate to a kind of pivot structure of circuit breaker, specifically is a kind of breaker rotating axis component of preventing electric arc form back burning.
Background technology
The rotating axis component of circuit breaker generally comprises a rotating shaft matrix and is installed in moving contact in the cavity of rotating shaft matrix, the pivoted arm leading portion of moving contact stretch out the rotating shaft matrix and around the shaft the matrix center rotate the contact of pivoted arm front end and fixed contact contact matching.The rotating axis component of this structure in the course of the work, the electric arc that dynamic and static contact is charged to be produced when disconnecting is scurried in the cavity that enters rotating shaft after easily, thus the miscellaneous part in the countershaft causes damage, and has influenced the functional reliability of equipment.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can effectively prevent to scurry behind the electric arc enter rotating shaft, and the breaker rotating axis component of simple in structure, easily manufactured preventing electric arc form back burning.
The breaker rotating axis component of preventing electric arc form back burning of the present invention includes a rotating shaft matrix, in the cavity in the rotating shaft matrix moving contact is installed, the pivoted arm of moving contact matrix center around the shaft rotates, the pivoted arm front end stretches out the rotating shaft matrix and is provided with and is used for the contact that cooperates with fixed contact, also be connected with the fire retardant insulating plate in the pivoted arm inboard, the main body of fire retardant insulating plate is arc surfaced, and it can slide along with the rotation of the pivoted arm cylindrical outer surface along the rotating shaft matrix.
The pivoted arm of above-mentioned moving contact can be provided with a pair of symmetrically, and connects fire retardant insulating plate separately respectively.This structure is applicable to the circuit breaker of double-breakpoint structure.
The present invention is simple in structure, easily manufactured, owing to be provided with the fire retardant insulating plate in the pivoted arm inboard, when dynamic and static contact disconnects, the fire retardant insulating plate can slide along the rotating shaft outer surface of matrix along with the rotation of pivoted arm, cavity in the rotating shaft is covered up, enter rotating shaft thereby can prevent from effectively to scurry behind the electric arc.
