ZWT type outdoor three-phase AC high voltage automatic recloser (hereinafter as recloser) is an outdoor power distribution unit with 40.5kv, 50/60Hz frequency, suitable for substation feeder side and power distribution system protection, control in industrial and mining enterprises, and other places where frequent switch operation is needed. It is composed of outdoor high voltage vacuum circuit breaker and automatic reclosing controller.
The circuit breaker body, with vacuum arc extinguishing, simple structure, strong breaking capacity, long life and micro-processor based controller, is modular designed, easy to operate and maintain. It is a kind of intelligent device, integrating power and relay protection, reclosing control, fault recording, remote control, remote measurement, remote signaling and remote adjustment.
The reclosing controller is mainly used in 40.5kv (and below) power distribution network, to control and monitor line and equipments. It is a necessary in the protection and control of pole mounted recloser. It is a FA-RTU( feeder automation- remote terminal unit).
