Abstract

An operating system of a vacuum circuit breaker. The whole operating system includes a framework, a rotating main shaft, an energy storage mechanism, a switching-on mechanism, a switching-on transmission mechanism, a switching-off transmission mechanism and a switching-off mechanism which are matched and connected, all the parts can be mounted in advance, the structure is simple, and assembling is more convenient; switching-on energy storage maintenance is realized through limiting cooperation of a locating pin, a switching-on pawl and an eccentric locating shaft, compared with existing cooperation of a switching-on half shaft and a switching-on rotating pawl, the structure is simpler, and energy storage maintenance is more stable; a d the switching-off pawl is designed to be a cross structure, original rotating swing arm, switching-off half shaft and switching-off rotating pawl are replaced, the structure is simpler, a switching-off driving structure, a limiting structure and a switching-off crank arm are arranged in the periphery of the switching-off pawl and are matched with four ends of the switching-off pawl, the layout is more reasonable, and assembling is simpler.

Description

Technical field [0001] The invention relates to a vacuum circuit breaker, in particular to an operating system of the vacuum circuit breaker. Background technique [0002] The operating system of the vacuum circuit breaker is an important component that makes the vacuum circuit breaker solid-sealed pole moving contact and static contact open and close instantaneously. It must complete energy storage, energy storage maintenance, closing, closing maintenance, and opening reset Therefore, the operating system of the existing vacuum circuit breaker must contain a large number of parts, and these parts must be installed in the same frame, which is difficult to assemble. [0003] A Chinese invention patent application (application publication date: 2013.12.18, application publication number: CN 103456558 A) discloses an operating mechanism of a vacuum circuit breaker, which divides the operating mechanism into a frame, an energy storage operating unit, and closing and opening execution u...
