China Wholesale VBI Vacuum Circuit Breaker Suppliers – ZW32-12F Outdoor high voltage vacuum circuit breaker (watchdog switch) – Timetric Detail:

General

ZW32-12 Outdoor high voltage vacuum circuit breaker (watchdog switch) is an outdoor high-voltage power distribution switchgear device with rated voltage of 12KV and three-phase AC of 50 Hz. The circuit breaker is mainly used for breaking and closing the load current. The circuit breaker is mainly used for breaking and closing the load current and overload current in the power system. Short-circuit. quick-break. grounding profection, optional reclosing times, local remote control and remote communication functions. suitable for protection and control in substation and industrial and mining enterprises’ distribution systems.When the internal fault of the T-type wiring of the 12Ky line occurs. or although it occurs inside the user’s incoming line switch, but the protection action time limit and the substation outlet switch protection are not proper, the substation outlet switch protection will be opened. If the fault is permanent and the substation coincides unsuccessfully, an accident in the medium voltage user community will power down the entire distribution trunk. Such common incidents in the power grid will cause significant losses to society. ZW32-12 outdoor high voltage vacuum circuit breaker (watchdog switch) (hereinafter called circuit breaker is installed in the responsibility boundary of the overhead line, that is the front section of the user incoming line. The single-phase ground fault and the phase-to-phase short-circuit fault in the user will be automatically cut off to avoid the fault in the user boundary and the power transmission trunk and ensure the safety of power users of faulty users and improve the reliability of power consumption.
