Problems solved by technology

[0002] The operating mechanism of the vacuum circuit breaker is an important part that makes the moving contact and the static contact of the vacuum circuit breaker's solid-sealed pole instantly open and close. It needs to complete energy storage, energy storage maintenance, closing, closing maintenance, and opening reset and other actions, so the operating mechanism of the existing vacuum circuit breaker must contain many parts, and these parts must be installed in the same frame, which is difficult to assemble; It can only be used in conjunction with the vacuum circuit breaker of its corresponding specifications, and the versatility is poor

Abstract

The invention discloses an operating mechanism of a vacuum circuit breaker. The operating mechanism of the vacuum circuit breaker comprises a framework, an energy-storing manipulating unit and a switching-on and switching-off execution unit, wherein the energy-storing manipulating unit and the switching-on and switching-off execution unit are arranged on the framework. The energy-storing manipulating unit comprises an energy-storing mechanism, a switching-on mechanism and a switching-off mechanism. The energy-storing mechanism comprises an energy-storing shaft, and the switching-on mechanism comprises a switching-on semi shaft, a switching-on rotary latch and a driving cam fixed to the energy-storing shaft; after the energy-storing shaft is in the energy-storing state, the energy-storing shaft can be matched with the driving cam and the switching-on semi shaft through the switching-on rotary latch to keep storing the energy; the switching-off mechanism comprises a switching-off semi shaft and a switching-off rotary latch fixed to the energy-storing shaft; the switching-on and switching-off execution unit comprises a rotary main shaft, a driving connecting lever and a maintaining connecting lever are arranged on the rotary main shaft, the switching-on semi shaft rotates and drives the cam to impact the driving connecting lever to enable the rotary main shaft to rotate and accomplish the switching-on action and to be matched with the switching-off semi shaft and the maintaining connecting lever through the switching-on rotary latch to keep in the switching-on state; the switching-off action is achieved by rotating the switching-off semi shaft; the operating mechanism of the vacuum circuit breaker is designed into different modular units, is convenient to assemble and is strong in universality.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breaker manufacture, in particular to an operating mechanism of a vacuum circuit breaker. Background technique [0002] The operating mechanism of the vacuum circuit breaker is an important part that makes the moving contact and the static contact of the vacuum circuit breaker's solid-sealed pole instantly open and close. It needs to complete energy storage, energy storage maintenance, closing, closing maintenance, and opening reset and other actions, so the operating mechanism of the existing vacuum circuit breaker must contain many parts, and these parts must be installed in the same frame, which is difficult to assemble; It can only be used in conjunction with the vacuum circuit breaker of its corresponding specifications, and its versatility is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an operating mechanism of ...
