Vacuum circuit breakers are generally divided into a plurality of voltage levels. Low type generally used for explosion-proof electrical use. Like mine, etc. The main structure of the vacuum circuit breaker consists mainly of three parts: a vacuum interrupter, electromagnetic or spring actuator, brackets and structure of his parts. Vacuum breaker breaker technical standards in our country over the past decade has been vigorous development. Products from the past ZN1 ~ ZN5 several varieties grown to more than tens of models, the variety Shanghai high-voltage vacuum circuit breaker, rated current up to 5000A, breaking current 50kA reached a good level, and has developed into a voltage rating up to 35kV. Before the 1980s, the vacuum breaker at the initial stage of development, technology continues to explore, develop technical standards can not be until 1985 before the development of relevant product standards. Welcome to inquire buy! 35kV vacuum circuit breaker in the following system of high voltage circuit breaker applications are power plants, substations and distribution equipment important electrical equipment, which bears the control and protection of the task. Normal and turned off by it to the load circuit, by its failure to cut Anhui fault circuit voltage vacuum circuit breaker, to limit the scope of Jiangsu accident voltage vacuum circuit breaker to ensure safe operation. Therefore, the high voltage circuit breaker select appropriate or not directly related to the generation of system security, power supply, that is related to our national economic production ...... welcome to inquire to buy!
