ZW32-12 Outdoor high voltage intelligent dividing vacuum circuit breaker

•product overview:

China ZW32 12 outdoor high voltage intelligent dividing vacuum circuit breaker, induction AC 50Hz outdoor distribution equipment. It is mainly used for opening and closing the load current, overload current and short circuit current in the power system. It is suitable for protection and control in substation and power distribution system of industrial and mining enterprises, especially in rural power grid and places with frequent operation. This product and the controller matching, can meet the distribution automation system requirements, and can reliably and effectively complete the traditional coincidence function.

•Characteristics of new on-post switches:

China ZW32 12 outdoor high voltage intelligent dividing vacuum circuit breaker (hereinafter referred to as circuit breaker) is rated voltage 12kV, three-phase AC 50Hz outdoor distribution equipment. It is mainly used for load current, overload current and short circuit current in power system. It is suitable for protection and control in urban and rural power grid, especially in places with frequent operation.

The China ZW32 12 outdoor high voltage intelligent dividing vacuum circuit breaker and the intelligent controller BKM600 FDR cooperate as the watchdog of the distribution network, which is specialized in solving the intelligent controller of 10KV user branch grounding and short circuit fault. In order to avoid the fault of the distribution network user branch line or improper protection coordination and affect the whole feeder power outage, and reduce the responsibility dispute between the power supply department and users, Construct user demarcation measurement and control system based on user demarcation load and user demarcation switch measurement and control unit, commonly known as the “watchdog” of distribution network
