The TCHZ-12 series outdoor high voltage vacuum automatic reclosing device is used in the three-phase distribution network system of AC 50Hz, voltage 10-12KV. The recloser is a high voltage switch device capable of automatically performing an opening and reclosing operation in an AC line according to a predetermined breaking and overlapping sequence, and automatically resetting or latching thereafter. It is used in conjunction with a breaker so that the distribution automation can be realized without other control system. This kind of system can quickly separate and isolate faults, reducing the power outage to the minimum. It is the ideal equipment for the urban rural power network transformation, and the reclosing device can be fitted with isolating switches according to the requirements of the users.
