High-voltage switches are also called circuit breakers, generally referring to electrical equipment with a rated voltage of 3kV and above, used to open and close electrical circuits. For the control and protection of the power system, it depends on the function of the high voltage switch. The high-voltage switch control power system mainly needs to put power equipment or lines into or out of operation according to the operation requirements of the power system. The main protection of the power system is that when the circuit fails, the high-voltage switch can quickly cut off the faulty part from the power system, so as to ensure that other parts of the power system continue to operate normally.

Therefore, in routine preventive tests, it is very important to detect the dynamic characteristics of high-voltage switches. So, how to detect the dynamic characteristics of the high-voltage switch?


To detect the dynamic characteristics of the high-voltage switch, the high-voltage switch dynamic characteristic tester can be used to test the high-voltage switch. Because of its large voltage adjustable range, this instrument is almost suitable for testing the mechanical characteristics of various types of GIS combination electrical appliances, SF6 switches, vacuum switches, and oil switches. And because the instrument has strong anti-interference ability, even when the bypass bus of the 500KV substation is live, the test can be easily completed and the measurement is accurate. In the test, every time the high-voltage switch is actuated, the instrument can automatically measure all the test data and the corresponding waveform chart, which is convenient for the power tester to view the results. And because the price of this instrument is moderate, the test equipment is more popular among electricians.


How to detect the dynamic characteristics of high voltage switches? Our suggestion is to use a high-voltage switch dynamic characteristic tester to get it done. This instrument is intelligent in testing, powerful in functions, accurate in test data, strong in anti-interference, and moderate in price. It is suitable for testing the dynamic characteristics of high-voltage switches.
