Medium voltage vacuum circuit breaker has made great progress, and achieved good results

Medium voltage vacuum circuit breaker has made great progress, and achieved good results, especially in the performance of the 12 kV voltage level, vacuum circuit breakers predominant. Currently, 12 kV outdoor vacuum circuit breakers are equipped with a  Electric energy meter  actuator actuator majority. Currently, outdoor vacuum circuit breaker products tend to focus on the design of the main circuit breaker and  mcb circuit breaker e, while ignoring the actuator in operation life. All circuit breakers life is ultimately reflected in the contact switching operation, while the switching operation is achieved through the actuator. Therefore, the actuator's work performance, reliability and quality merits, the circuit breaker performance and reliability plays an extremely important role.
