Switch Mechanical Characteristic Tester

KEKGY-F High Voltage Switch Mechanical Characteristic Tester

(12-breakpoint touch screen)

I. Product Overview:
      With the development of science and technology, the requirements for the safety and reliability of electricity use are increasingly high. High voltage circuit breakers bear 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. Mechanical characteristic parameters are one of the important parameters for judging the performance of circuit breakers.
      The KEKGY-F High Voltage Switch Mechanical Characteristic Tester (12-breakpoint type) is designed based on the latest "High Voltage AC Circuit Breakers" GB1984-2003 as the blueprint, and in accordance with the national 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 is suitable for testing parameters of almost all models of metal contact SF6 switches, GIS combination appliances, vacuum switches, oil switches, pole-mounted switches, contactors, etc., produced domestically and internationally.
