Product Introduction

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. The ZWKC-GA high-voltage switch characteristic comprehensive tester (high-voltage switch mechanical characteristic tester) is based on the latest “High-voltage AC Circuit Breaker” GB1984-2003 as the design blueprint, and refers to the People’s Republic of China Electric Power Industry Standard “General Technical Requirements for High Voltage Test Equipment” 》Part 3, DL/T846.3-2017 is the design basis, which provides convenience for the dynamic analysis of various circuit breakers, and can accurately measure various voltage levels of less oil, more oil, vacuum, and sulfur hexafluoride The mechanical dynamic characteristic parameters of high-voltage circuit breakers. 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.
