Product Structure
ZW32M-12 type outdoor high voltage vacuum circuit breaker is rated voltage 12kV, three-phase AC 50Hz outdoor distribution equipment, which is mainly used for breaking, closing power system load current, overload current, short-circuit current. For substation and industrial and mining enterprises distribution system for the protection and control of the role and place of rural power grids frequent operation.
The circuit breaker has small size, light weight, anti-condensation, maintenance-free characteristics, can adapt to poor weather conditions and dirty environments.
The models with permanent magnet operation mechanism operates: since the permanent action energy operating mechanism provided by a permanent magnet, the switch quickly to keep the points off position, a small number of mechanical parts, mechanical transmission chain is short, thus greatly improving the switch reliability and mechanical life.
