Problems solved by technology

The problem existing in the existing three-phase common-tank vacuum circuit breaker is that the transmission stroke of the toggle mechanism corresponding to the movable conductive rod of each phase is relatively long, so that the energy consumption between the operating mechanism and the movable conductive rod is relatively large, and the transmission stroke is long and difficult to dial. The complexity of the moving mechanism is not conducive to the synchronous operation of the actions of each toggle mechanism; at the same time, the complex toggle mechanism also occupies a large box space, which is not conducive to the miniaturization of the three-phase common box vacuum circuit breaker.

Abstract

The invention relates to a three phase total box vacuum circuit breaker and a circuit breaker toggle mechanism thereof. The circuit breaker toggle mechanism comprises a drive shaft driven by a corresponding operating mechanism, wherein three insulation shifting forks, which are respectively used for corresponding with arc extinguish chamber moving electric conduction rods of three phases, are arranged on the drive shaft along the axial direction of the drive shaft in intervals, two drive structures are oppositely arranged on two shifting fork arms of each insulation shifting fork, and the drive structures are used for connecting with corresponding arc extinguish chamber moving electric conduction rods in driving mode so as to toggle the corresponding arc extinguish chamber moving electric conduction rods to move forward and back when the drive shaft swings back and forth. The invention provides a circuit breaker toggle mechanism which is simple in structure and high in driving efficiency.
