With the development of society, people's requirements for the safety and reliability of electricity use are getting higher and higher. High-voltage circuit breakers play the dual role of control and protection in the power system, and their performance directly affects the safe operation of the power system. Mechanical characteristic parameters are one of the important parameters for judging the performance of circuit breakers. JY-6 High-Voltage Circuit Breaker Mechanical Characteristic Tester is designed based on the latest "High-Voltage AC Circuit Breakers" GB1984-2003, and in accordance with the People's Republic of China electric power industry standard "General Technical Conditions for High-Voltage Test Equipment" Part 3, DL/T846.3-2004 High-Voltage Switch Comprehensive Tester as the design basis. It provides convenience for dynamic analysis of various circuit breakers and can accurately measure the mechanical dynamic characteristic parameters of various voltage levels of low-oil, multi-oil, vacuum, sulfur hexafluoride, and other high-voltage circuit breakers.
