Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation equipment, and in particular relates to a linear motor operating mechanism of a high-voltage circuit breaker, which is suitable for intelligent operation of the circuit breaker. technical background [0002] The high-voltage circuit breaker plays the role of control and protection in the power grid. It is an important equipment in the field of power transmission and transformation. It not only ensures the long-term operation reliability of the circuit breaker, but also meets the requirements of the arc extinguishing characteristics for the operating mechanism. For this reason, circuit breakers are required to have good operating performance. The circuit breaker operating mechanism used today adopts spring, hydraulic or pneumatic technology, all of which are traditional mechanical designs. They are mainly composed of connecting rods, locks, and energy supply systems. ...
