ZN12-12 indoor high-voltage vacuum circuit breaker rated voltage of 12KV and the following indoor high-voltage switchgear, mainly installed in fixed switchgear, for industrial and mining enterprises, power plants and substations for the protection and control of electrical facilities, and is suitable for breaking important loads and frequent operation of the place!
ZN12 series vacuum circuit breakers are indoor high-voltage switchgear device with rated voltages of 12kV, 24kV, and 40.5kV, and three-phase AC 50Hz. It is a domestic product developed by introducing German Siemens 3AF technology.The operating mechanism of the circuit breaker is a spring energy storage type, which can be operated by AC or DC, or manually. The circuit breaker has simple structure, strong breaking capacity, long service life and complete operation functions. And there is no danger of explosion, and the maintenance is simple. It is suitable for the control or protection switch of power transmission and distribution systems such as power plants, substations and industrial and mining enterprises, especially suitable for breaking important loads and frequent operation places. The installation form of the circuit breaker in the switch cabinet can be either a fixed type or a withdrawable type circuit breaker.This product complies with relevant standards such as GB1984, JB3855 and IEC62271-100 “High Voltage AC Circuit Breaker”.
Advantages:
1.The circuit breaker passed the appraisal of the Ministry of Machinery and the Ministry of Electric Power in August 96th,which means the quality is absolutely guaranteed.
The circuit breaker mechanism is integrated with the switch, and the special spring energy storage type actuator mechanism can be operated by AC and DC energy storage or manually operated.
