Based on the energy mode of vacuum circuit breakers, common operating mechanisms can be categorized into manual operating mechanisms, magnetic induction operating mechanisms, spring operating mechanisms, motor operating mechanisms, pneumatic operating mechanisms, and hydraulic operating mechanisms.

The currently widely used QF operation organization is the mechanical transmission of machinery and equipment, internally equipped with an emergency stop spring and a shutdown spring. It utilizes the energy released from the shutdown spring to store energy in the spring and a cam-driven mechanism that also stores energy in the spring. The cam-driven mechanism is equipped with a drive wheel that is fixed to the cam and a drive gear that engages with a large gear, powered by a drive source. A portion of the drive wheel is set to mesh with the small gear immediately after the shutdown spring stores energy, allowing for stable engagement between the drive gear and the drive wheel. The load from the drive source is pulse-free, thus reducing its volume. It is suitable for large space disconnect switches.

QF's electric operation organization. Due to the technical field of working voltage switchgear, it involves the electric operation mechanism of the isolator. The isolator electric operation organization includes the driving machine spindle, the main transmission gear inner ring line, and the driving machine spindle according to the ratchet structure, the main transmission gear, and the driving motor driving force output shaft are transmitted according to the speed regulation organization; the driving machine spindle below is fixedly connected with a connecting gear, the crank outer edge pin is connected with the roller bearing and the roller, the roller is confined to the curved rail, and the roller is set to rotate the operating lever of the isolator. This utility model patent has a compact structure, small size, simple transmission method, easy operation, high operation stability, and high response time.
