ZW32-12F Outdoor High Voltage Vacuum Demarcation Circuit Breaker Switch

ZW32-12F outdoor high-voltage vacuum demarcation circuit breaker (watchdog switch) is an outdoor power distribution equipment with a rated voltage of 12kV three-phase AC 50Hz. The circuit breaker is mainly used for breaking and closing the load current, overload current and short circuit, quick break, grounding protection, optional reclosing times, local remote control and remote communication in the power system, and is suitable for protection and control in the power distribution system of substations and industrial and mining enterprises. When the user of the T-type wiring of the 12kV line fails, or although it occurs on the inside of the user's incoming switch, the protection action time limit and the protection of the substation outgoing switch are improper, which will cause the protection of the substation outgoing switch to open and open. If the fault is permanent and the substation overlap is unsuccessful, an accident within the boundaries of a medium voltage user will cause th
