With the development of society people have higher and higher requirements for the safety and reliability of power consumption. High-voltage circuit breakers have the dual tasks of control and protection in the power system. The performance of the power circuit is directly related to the safe operation of the power system. The mechanical characteristic parameter is one of the important parameters for judging the performance of the circuit breaker. The Breaker Analyzer is a special instrument developed by the company to meet the needs of various high-voltage switch operating characteristics tests. It can accurately measure low-oil multi-oil vacuum sulfur hexafluoride and other high-voltage circuit breakers of various voltage levels. Mechanical dynamic characteristics parameters. The instrument adopts large screen display Chinese characters prompt man-machine dialogue mode operation Chinese characters display results and printouts with intelligent multi-function accurate data strong anti-interference simple operation small size light weight and beautiful beauty.
