With the development of society, people have higher and higher requirements for the safety and reliability of electricity use. High-voltage circuit breakers are responsible for the dual tasks of control and protection in the power system, and their performance is directly related to the safe operation of the power system. The mechanical characteristic parameter is one of the important parameters to judge the performance of the circuit breaker. This instrument is specially designed for circuit breaker timing test and can accurately measure key time parameters of circuit breakers, while also serving as a professional circuit breaker vacuum bottle tester to assist in evaluating the insulation performance of vacuum circuit breakers.
