The invention discloses an opening and closing mechanism for a vacuum circuit breaker, and relates to the field of opening-closing mechanisms. The mechanism comprises a shell. Two connectors are arranged in the shell, a through hole is formed in the center of the inner wall of one side of the shell, an adjusting column is rotationally installed in the through hole, an adjusting knob is fixedly installed at one end of the adjusting column, a stirring rotary disc is fixedly installed at the other end of the adjusting column, and two fan-shaped blocks are fixedly installed on the side portion ofthe stirring rotary disc. The operating mechanism has enough operating work to overcome the electrodynamic force. Through the design of the pressure sensor, under a stable state, the size of the torque applied to the metal guide rod by the clockwork spring can be detected, when the torque is too small and deviates from a specified range value, the servo motor is started for charging, the servo motor drives the pinion to rotate, the pinion drives the straight gear ring to rotate, charging of the clockwork spring is completed in the rotating process of the straight gear ring, and therefore energy storage is achieved, and large enough operation work is generated.
Description
technical field [0001] The invention relates to the technical field of opening and closing equipment, in particular to an opening and closing mechanism for a vacuum circuit breaker. Background technique [0002] "Vacuum circuit breaker" is named because the 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 in the power grid is relatively popular. The vacuum circuit breaker is an indoor power distribution device in a 3-10kV, 50Hz three-phase AC system. It can be used for the protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is especially suitable for In places requiring oil-free, less maintenance and frequent operation, circuit breakers can be configured in central cabinets, double-layer cabinets and fix...
