Vacuum circuit breaker with damping structure

Abstract

A vacuum circuit breaker with a damping structure disclosed by the present invention comprises a circuit breaker body and a damping installation structure connected with the circuit breaker body, the damping installation structure comprises an installation frame, the installation frame is provided with an installation screw hole, the installation frame is fixedly provided with an installation cavity, the inner wall of the installation cavity is provided with at least three limiting clamping grooves, a limiting clamping block is integrally formed at the bottom of the side wall of the circuit breaker body, a C-shaped warping rod is arranged in the middle of a limiting clamping groove, a vertical inserting groove is formed in the side wall of the limiting clamping block, a guiding round hole is formed in the bottom wall of the mounting cavity, a guiding column rod is integrally formed at the bottom of the circuit breaker body, a buffer tension spring is fixed between the upper part of the C-shaped tilting rod and the inner wall of the limiting clamping groove, and a buffer spring is fixed between the bottom surface of the circuit breaker body and the bottom wall of the mounting cavity. The vacuum circuit breaker is reasonable in structural arrangement, the installation stability is guaranteed, the double damping performance is achieved in cooperation with the buffer springs, the damping reliability is guaranteed, the applicability is high, and the practicability is good.

Description

technical field [0001] The invention belongs to the technical field of vacuum circuit breakers, and in particular relates to a vacuum circuit breaker with a shock absorbing structure. Background technique [0002] Vacuum circuit breaker is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. The application is more popular. [0003] Due to the relationship between the installation position and external vibration, the existing vacuum circuit breaker is easy to contact and separate through the contact and separation between the bolt contacts. Because the circuit breaker is not stable enough, it is difficult to control and has poor working stability. Contents of the invention [0004] The object of the present invention is to provide a vacuum circuit breaker with a shock-abso...
