Zgf DC High Voltage Generator During 60-400kv (Hipot Tester)

ZGF DC High Voltage Generator During 60-400KV(Hipot Tester)


I. Introduction
ZGF Series DC High Voltage Generator is DC high voltage power supply equipment which is applied in power cable test and arrester test in power system.

II. Features:
1. Using a new double voltage material and processed by fluorine silicon, the generator has powerful electric functions, and can be operated under very wet conditions.
2. Using 35-50 KHZ inverter frequency, PMW pulse width modulation, small ripple factor, and light weight.
3. With imported full shielding case and main components, the generator has a good anti-interference function and it's very stable and reliable.
4. Adopting voltage closed-loop feedback, the generator provides a stable voltage.
5. High -voltage side microammeter is with metal shell, connected the sample room with shielded wire, effectively eliminating the influence to the measured value from stray current. It has high measurement accuracy, and it can change shift of micro ammeter between low range and high range automatically.
6. Can test leakage current under 0.75 times DC reference voltage of Zinc-Oxide Arrester.
7. With perfect rapid protection circuit, when high voltage continues discharging to ground, it causes no damage to the product
8. The Intermediate frequency transformer has a special design, small size, and large capacity.
9. ZGF DC High Voltage Generator has many protection functions, such as low pressure flow, low overvoltage, high pressure flow, high overpressure, zero protection, grounding protection etc, which highly improve operators' safety.
