With the development of society, people have increasingly high requirements for the reliability of electricity use. High voltage circuit breakers play a dual role in control and protection in the power system, and their performance directly affects the operation of the power system. Mechanical characteristic parameters are one of the important parameters for judging the performance of circuit breakers. The TZY-SC8001 high-voltage switch action characteristic tester, also known as the high-voltage switch mechanical characteristic tester, is designed based on the "High Voltage AC Circuit Breaker" GB1984-2003 as the blueprint, and refers to the Chinese power industry standard "General Technical Conditions for High Voltage Testing Equipment" Part 3, DL/T846.3-2004 as the design basis. It provides convenience for dynamic analysis of various types of circuit breakers and can accurately measure the mechanical dynamic characteristic parameters of low oil, high oil, vacuum, sulfur hexafluoride and other high-voltage circuit breakers of various voltage levels. High voltage circuit breakers play a dual role in control and protection in the power system, and their performance directly affects the operation of the power system. Mechanical characteristic parameters are one of the important parameters for judging the performance of circuit breakers.

1. Time

This machine can measure the inherent opening and closing time, in-phase synchronization time, face-to-face synchronization time, metal short time and no current time during the closing opening, opening closing, and opening closing opening processes of 12 metal fracture surfaces, as well as the closing bounce time. Some models can also measure the pre switching time of the closing resistance.

2. Speed and Travel
