RVE-12 type household permanent magnet internal sealed high voltage vacuum circuit breaker is a three-phase AC 50Hz rated voltage 12kV indoor switch equipment of power system, as the protection and control of power grid equipment, power equipment of industrial and mining enterprisesCell. Suitable for requiring frequent operation under rated operating current or repeatedly breaking short circuit current.
The circuit breaker adopts an integral design of an actuating mechanism and a breaker body, which can be used as a fixed installation unit or a special propulsion mechanism to form a handcart unit.
This type of product is equipped with bistable permanent magnetic actuator. The mechanism is equipped with permanent magnet, which provides permanent force by permanent magnet and keeps the switch in close and split state. Compared with conventional spring operating mechanism, it has large number of machine parts The mechanical reliability of the switch is greatly improved, and the mechanical life is greatly increased.
