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, variety, rated current up to 5000A, 50kA breaking current reaches a good level Yancheng vacuum circuit breakers, and has grown to voltages up to 35kV grade. Before the 1980s, the vacuum breaker at the initial stage of development, technology continues to explore, it can not develop technical standards Taizhou vacuum circuit breakers, until 1985 after the development of relevant product standards. Welcome to inquire buy! Chinese low-voltage circuit breaker manufacturers currently mainly in Beijing, Tianjin, Liaoning, Shanghai, Jiangsu, Zhejiang, Guangdong and other places of vacuum circuit breakers, in promoting economic development while Zhenjiang vacuum circuit breakers, also exposed many problems. Mainly in the following two points: 1. small-scale enterprises, and the excessive number. 2. Regional structural convergence, redundant construction serious. Chinese low-voltage electrical industry due to the blind on the project, setting up shops, regional industry convergence serious, low-level redundant construction, resulting in the production of excess energy, low utilization of raw materials, low cost and regional protection, vicious competition and other consequences. Yancheng vacuum circuit breakers, Huayi Electric Power (certified), vacuum circuit breaker provided by Xian Huayi power plant.
