Brief Introduction
The GKC-F High Voltage Switch Dynamic Characteristic Tester is convenient for wiring and simple to operate. During operation, only one closing (or opening) action is needed to obtain all data of closing (or opening). It can choose to save 50 sets of data, provide later query and upload to computer for permanent storage, and also allow on-site review and printing of all data and motion curve diagrams. It uses Chinese prompts for human-machine dialogue operation. The data is accurate, with strong anti-interference capability, small size, light weight, and elegant appearance.
Detailed Description
With the development of society, people have increasingly higher requirements for the safety and reliability of electricity use. High-voltage circuit breakers play a 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 circuit breaker performance. The GKC-F High Voltage Switch Dynamic Characteristic Tester is designed based on the latest "High Voltage AC Circuit Breakers" GB1984-2003, and refers to 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 types of circuit breakers and can accurately measure the mechanical dynamic characteristic parameters of high-voltage circuit breakers of various voltage levels, including oil-minimum, multi-oil, vacuum, and SF6 types.
