High power IGBT devices and driving technology, and special shielding, isolation, and grounding measures are adopted based on electromagnetic compatibility theory. The DC high-voltage generator achieves high quality, portability, and can withstand rated voltage discharge without damage. It has the characteristics of high output power and small size, reliable overvoltage, overcurrent, and zero position closing protection functions, and has a 0.75 times voltage switching function. It is mainly suitable for power departments, industrial and mining, metallurgy, steel and other enterprises to conduct DC withstand voltage tests or DC leakage current tests on high-voltage electrical equipment such as zinc oxide lightning arresters, power cables, transformers, circuit breakers, generators, etc.
ZGF-200/5 DC High Voltage GeneratorScope of application:
1. Conductivity current test of valve type lightning arrester.
2. DC withstand voltage test and leakage current measurement of power transformers.
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 for zinc oxide lightning arrester.
