Product introduction
ZGF series DC high-voltage generators use high-frequency voltage doubler circuits, apply advanced PWM high-frequency pulse width modulation technology, closed-loop adjustment, and use large voltage feedback to greatly improve voltage stability. Use high-performance IGBT devices and driving technology with excellent performance, and adopt special shielding, isolation and grounding measures according to the theory of electromagnetic compatibility. The DC high voltage generator has realized high quality, portable, and can withstand rated voltage discharge without damage. It has the characteristics of large output power and small volume, reliable overvoltage, overcurrent and zero-position closing protection functions, with a voltage switching function of 0.75 times. Mainly applicable to power sector, industrial and mining, metallurgy, iron and steel and other enterprise power departments to conduct DC withstand voltage test or DC leakage current test on high voltage electrical equipment such as zinc oxide arresters, power cables, transformers, circuit breakers and generators.
Scope of application
1. Electrical conductivity test of valve arrester.
2. DC voltage withstand 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 of zinc oxide lightning arrester and leakage current test at 0.75U1mA.
Product Features
1.The DC high voltage generator has a small ripple coefficient, stable and reliable voltage output, no noise, and good reliability
2.With over-voltage, over-current, zero-voltage start-up and fault protection functions, the voltage protection value can be set and displayed intuitively
3.Digital display of voltage and current, and readings when power is on, which is convenient for monitoring the output status
4.with a voltage conversion of 0.75 times, convenient for testing zinc oxide lightning arresters
5.Compact product structure, small size, easy to carry
