| High Voltage Switch Time Characteristic Tester Darui Electric recommends for you Product Introduction With the development of society, people's requirements for the safety and reliability of electricity use are increasingly high. High-voltage circuit breakers play a dual role of control and protection in the power system. 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. |
The High Voltage Switch Dynamic Characteristic Tester is a special instrument developed by our company to meet the needs of testing the dynamic characteristics of various high-voltage switches. It 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. Its main feature is that, in addition to meeting the dynamic characteristic testing of general high-voltage switches on the market, it also supports the testing of Siemens graphite contact switches, and can reliably test the dynamic resistance waveforms of three contacts of graphite contact switches. The instrument adopts a large-screen display, Chinese prompts for human-machine dialogue operation, displays results in Chinese and prints them out. It has the advantages of intelligence, multiple functions, accurate data, strong anti-interference, simple operation, small size, light weight, and beautiful appearance.
