UHV-410 High Voltage Switch Operating Power Supply-Catalog

Product catalog summary

Product Introduction
The UHV-410 High Voltage Switch Operating Power Supply is designed for the operating voltage test of high-voltage circuit breakers, a crucial preventive measure to ensure their safe operation in power systems. Traditional methods using DC systems or AC power have significant drawbacks, such as potential system collapse or safety hazards. This product provides an independent test power supply to mitigate these risks.

UHV-410 High Voltage Switch Operating Power Supply-Catalog-2

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...
