Permanent Magnet Outdoor Vacuum Circuit Breaker
Model：
HZW32-12
Overview：
A permanent magnet vacuum circuit breaker (short name VCB) is an outdoor high-voltage switchgear used in a three-phase AC 50Hz power grid with a rated voltage of 7.2~12kV. The VCB adopts a permanent magnet operating mechanism, compound with the control terminal and PT (power transformer) to form an intelligent circuit breaker, which is widely applicable to substation feeder terminals, distribution lines of industrial and mining enterprises, and urban and rural power grid transmission and distribution systems for protection and control, especially suitable for places with frequent operations and urban and rural power grid automatic distribution networks.

  1. Adopts vacuum arc extinction, Reliable breaking, The contact head wears less, and no maintenance required;

  2. Adopts epoxy resin composite as the external insulation material with good voltage resistance and weather resistance, no oil, without SF6, and environmental protection;

  3. Adopts a permanent magnet operating mechanism with a service life of up to 30,000 times, capable of quickly cutting off faults and realizing rapid protection;

  4. It can be equipped with an integrated isolation switch with obvious visible breaking points and anti-misoperation interlocking devices;

  5. Optional manual operating mechanism, capable of manual closing operation in emergencies.
