Wuhan UHV Power Technology Co.,Ltd.

Wuhan UHV Power Technology Co.,Ltd. The operating voltage test of high-voltage circuit breakers, commonly known as the "(high) low voltage test”, is a basic preventive electrical test to ensure the safe operation of high-voltage circuit breakers in power systems. At present, the power sector generally adopts the following two methods for testing: 1) Use the DC system of the on-site control cabinet as the test power supply, and adjust the voltage through a sliding line variable resistor for testing. The biggest drawback of this method is that if there is a short circuit or direct DC grounding...

Wuhan UHV Power Technology Co.,Ltd. ripple factor. Completely overcome the problem of instantaneous output voltage collapse caused by load voltage when using traditional rectifier power supply. 3) Reliable: The instantaneous current can reach 20A, with overcurrent and overvoltage protection, and equipped with AC/DC energy storage output interfaces. Can reliably use this product to directly conduct action voltage tests on high-voltage switches. 4) Durable: Good appearance, compact and lightweight, sturdy structure, capable of withstanding vibrations and impacts generated by frequent transportation,...
