CHZ□-12 Ac high voltage automatic reclosing
Release time:2015-06-05 22:37 Read:Time


●Overview
Outdoor high voltage vacuum automatic reclosing is used to pay 50HZ ,10 ~ 12KV three-phase voltage power distribution network system, the reclosing is to be able to order according to the predetermined breaking and overlap in the ac line, automatically open fracture and operation, and automatic reset or atresia after self control protection function of high voltage switch equipment used with breaking machine, etc, can not realize the distribution automation and control systems, this system can fast segmentation and isolate fault, will be a power outage range to a minimum, is the ideal equipment of the rural electric reform, the reclosing can be according to the requirements of the user with the isolating switch, etc.
