Brief Introduction
The GKC-F High Voltage Switch Dynamic Characteristic Tester is easy to wire and operate. Only one closing (opening) operation is needed to obtain all data of closing (opening). It can save up to 50 sets of data for later query and upload to computer for permanent storage. It also allows on-site review and printing of all data and motion curves. It features Chinese prompts and human-machine dialogue operation. The data is accurate, with strong anti-interference capability, compact 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 dual roles 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 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. 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, SF6, and other high-voltage circuit breakers.
