Operating mechanisms, also commonly referred to as driving mechanisms, are used in switchgear apparatuses to open or close the main and arc contacts during the breaking or closing operations of the equipment. They are a key component of the switchgear and directly affect the reliability and stability of the operation. Common operating mechanisms include spring mechanism, hydraulic mechanism, electromagnetic mechanism, permanent magnet mechanism, and disc spring mechanism.
