1.General description

ZW32-12C type outdoor H.V. vacuum automatic recloser is used in tri-phase distributed power system of AC 50 Hz, voltage 12kV. It can automatically breaking and reclosing operation in AC lines according to breaking and reclosing order, and then automatically restore, or lock H.V. switch equipment with control and protection function used with sectionalizer. It can realize distribution automatically without another control system. The system can rapidly subsection and isolate fault, reduce the range of power cut to least. It is the reasonable equipment for transforming urban and rural net, can be matched with isolating switch according to customers.

This circuit breaker should match with voltage transformer.
