NDGKC-VI High Voltage Switch Dynamic Characteristic Tester

Product Introduction

        With the development of society, the demand for safe and reliable electricity usage is increasing. High-voltage circuit breakers bear the dual tasks 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.

        High-voltage Switch Comprehensive Characteristic Tester (also known as High-voltage Switch Mechanical Characteristic Tester) is designed based on the latest standard "High-voltage Alternating Current Circuit Breakers" GB1984-2003, with reference to the power industry standard "General Technical Conditions for High-voltage Test Equipment" Part 3, DL/T846.3-2004. It provides convenience for dynamic analysis of various types of circuit breakers and can accurately measure the mechanical dynamic characteristic parameters of high-voltage circuit breakers such as low-oil, multi-oil, vacuum, and SF6 circuit breakers at various voltage levels.
