The DC high voltage generator has high output power, small size, reliable over-voltage, over-current, zero-crossing protection and 0.75x voltage switch. DC high-voltage generators are mainly used in the electric power sector, industrial/mining, metallurgy, steel and other fields, for the DC withstand voltage test and DC leakage current test of high-voltage electrical equipment such as zinc oxide arresters and power cables. Transformers, circuit breakers, generators.
Scope of application:
1. Conductivity test of valve arrester.
2. DC withstand voltage test and leakage current measurement of DC high voltage generator.
3. DC withstand voltage test and leakage current measurement of high voltage cables (35~500kV and below).
4. U1mA DC reference voltage test and 0.75U1mA leakage current test of zinc oxide arrester.
The DC high voltage generator has small ripple coefficient, stable and reliable voltage output, no noise, and good reliability. With over-voltage, over-current, zero-voltage start and fault protection functions, the voltage protection value can be set, and the display is intuitive. The voltage and current are displayed digitally, and the power supply has a reading, which is convenient for monitoring the output status. Through the voltage conversion of 0.75 times, the zinc oxide arrester can be easily tested. The product is compact in structure, small in size and easy to carry.
