ZW32-12

　　ZW32-12 outdoor column on vacuum circuit breaker (hereinafter referred to as circuit breaker) for a period of 12 kv, rated voltage of the three-phase ac 50 hz outdoor high voltage power distribution equipment. Is mainly used to open and close of electric power system load current, overload current and short circuit current. Suitable for transformer substation and industrial and mining enterprises for protection and control in power distribution system, more suitable for the urban and rural power grid and the site of frequent operation of construction and reform.

　　The circuit breaker with spring energy storage operation mechanism; Can be manual, electric operation and remote control points and closing operation. In circuit breaker side mounted to the isolating switch, form combination of outdoor high voltage vacuum circuit breaker, increases the visible isolation fracture, and has reliable interlocking operation. The circuit breaker operation can also USES the permanent magnetism operating mechanism; Provided by the permanent magnet retention, keep the switch in the closing position, less the number of mechanical parts, mechanical transmission chain is short, which greatly improves the reliability and mechanical life of the switch.

　　According to user requirements, ZW32-12 type circuit breaker can communicate with the corresponding controller with high pressure vacuum automatic reclosing, automatic segmentation, self-provided power operation, is the realization of the ideal equipment of power distribution automation system.
