Product Introduction
With the development of society, people have higher and higher requirements for the safety and reliability of electricity. The high-voltage circuit breaker is responsible for the dual tasks of control and protection in the power system, and its performance is directly related to the safe operation of the power system. Mechanical characteristic parameter is one of the important parameters to judge circuit breaker performance. The instrument provides convenience for dynamic analysis of various types of circuit breakers, and can accurately measure the mechanical dynamic characteristics of various voltage levels of high-voltage circuit breakers such as less oil, more oil, vacuum and sulfur hexafluoride. The high voltage circuit breaker is responsible for the dual tasks of control and protection in the power system, and its performance is directly related to the safe operation of the power system. Mechanical characteristic parameter is one of the important parameters to judge circuit breaker performance.
