High voltage circuit breaker arc extinguish chamber simulating system and tester evaluating system

Abstract

The invention discloses a high voltage circuit breaker arc extinguish chamber simulating system, which comprises an electric conductive support barrel, a fixed contact head electric conductive support frame, a fixed contact head electric conductive fixing plate, a fixed contact head and a moving contact head, wherein the electric conductive support frame is supported by the electric conductive support barrel and the electric conductive support frame is fixedly connected to the electric conductive support barrel; the fixed contact head electric conductive fixing plate is fixed on the top portion of the electric conductive support frame through an insulating fixation member; the fixed contact head is fixed on the fixed contact head electric conductive fixing plate through the electric conductive fixing member; a lower end of the fixed contact head is a contact finger; the moving contact head is facing to the contact finger by sequentially penetrating through the electric conductive support barrel in a vertically upward way; in addition, the invention also provides a high voltage circuit breaker tester evaluating system; when the high voltage circuit breaker arc extinguish chamber simulating system is in use, the high voltage circuit breaker tester evaluating system cooperates with a standard operation mechanism with known mechanical property parameters for evaluating and testing various circuit breaker movement property testers.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a high-voltage circuit breaker arc extinguishing chamber simulation system and a tester evaluation system. Background technique [0002] With the development of society, people's safety and reliability of power system are getting higher and higher. High-voltage circuit breaker (or high-voltage switch) can not only cut off or close the no-load current and load current in the high-voltage circuit, it has a fairly complete The arc extinguishing structure and sufficient current breaking capacity are responsible for the dual tasks of control and protection in the power system, and its 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 high voltage circuit breaker. The high-voltage circuit breaker mainly includes two parts: the operating mechanism...

AI Technical Summary

Problems solved by technology

If you directly buy a high-voltage circuit breaker for testing, it is expensive, and the price of the arc extinguishing chamber accounts for about 3 / 4 of the price of the circuit breaker
