ZW32-12G Medium Voltage High Voltage Outdoor Vacuum Circuit Breaker
The ZW32 vacuum circuit breaker is equipped with a spring energy storage mechanism, which can be operated manually, electrically and by remote control. It is possible to install isolation switch on the side of circuit breaker to form outdoor high voltage vacuum circuit breaker-outdoor high voltage isolation switch combination, which adds visible isolation break and has reliable interlock operation.
According to the user's request, it is an ideal equipment to realize distribution network automation to cooperate with the corresponding controller to form AC high voltage vacuum automatic reformer and automatic segment divider. ZW 32-12G/1250-20, ZW 32-12 series column high voltage outdoor vacuum circuit breaker is a three-phase AC 50Hz, rated voltage 12kv outdoor high pressure switch equipment. It is suitable for breaking and closing the load current, overload current and short circuit current of urban or rural distribution system.
The circuit breaker is a new miniaturized design with a fully enclosed structure and unique sealing technology for arc extinguishing chamber. The zw32-1G circuit breaker isolation switch combination is composed of two main parts of the ZW 32 circuit breaker isolation switch. A switching device capable of breaking and carrying current under normal loop conditions and of carrying and breaking current under abnormal loop conditions within a specified time.
It has the function of overload, short circuit and undervoltage protection, and has the ability to protect the line and power supply.
