Product Introduction
The ZW32-12 type double isolation double outlet outdoor high voltage vacuum circuit breaker is a control and maintenance equipment in the AC three-phase high voltage power distribution network with a rated voltage of 12KV and 50Hz. The recloser is an intelligent device that can be used in conjunction with the sectionalizer to realize power distribution automation without relying on another control system. The recloser is composed of a circuit breaker (and its operating mechanism), a controller, and a control power supply. In addition to being able to open and close normal and faulty high-voltage lines like the circuit breaker, it can also press The preset number of times of automatic reclosing is performed for multiple times so that the sectioner will act to isolate the faulty line during the reclosing interval, and the intact line will restore power; if the recloser fails for many times, the recloser will be closed and locked. At this time, At the other end of the ring network (or "hand in hand" network), the principle is that the recloser, which is closed and locked, is automatically closed when the lock is released, and the power supply can be restored immediately if the line is intact. Power grid automation can limit the scope of power outage to the smallest extent after a fault occurs, which has high social and economic benefits. The stupid product has the "four remote" remote communication function, which can realize optical fiber, microwave, carrier, radio and GSM.
