Shenheng Electric Power Equipment Co., Ltd.

& Overview of permanent magnet indoor high-voltage vacuum circuit breaker:
The permanent magnet indoor high-voltage vacuum circuit breaker is an indoor switching device with a three-phase AC rated voltage for the power system. It is used as a protection for power grid equipment and power equipment of industrial and mining enterprises. and control unit. It is suitable for places requiring frequent operation under rated operating current or multiple short-circuit currents. The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a special propulsion mechanism to form a handcart unit.
Performance advantages:
This type of product is equipped with a bistable permanent magnet operating mechanism. The mechanism is equipped with a permanent magnet. The permanent magnet provides a holding force to maintain the switch in the closing and opening states. It is different from the conventional spring. Compared with the operating mechanism, the number of mechanical parts is greatly reduced, and the mechanical rotating chain is shortened, thereby greatly improving the reliability of the switch and greatly increasing the mechanical life.
