Product Description

Product overview
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.

Products features

1,The output voltage is stable: the high-frequency voltage doubler circuit is applied, and the new PWM pulse width modulation technology and the voltage and current double closed-loop feedback technology are applied to improve the power supply adjustment rate and the load adjustment rate, so that the voltage stability is high and the ripple is small.

2,comprehensive protection: full protection function, with zero protection, over-voltage protection, over-current protection, breakdown protection, protection circuit uses nanosecond-level special sensor, action fast and reliable, effectively protect personal and equipment safety.

3,0.75U function: Add intelligent high-precision 0.75U function one-button button, press this button, the voltage and current will automatically jump to the 0.75U state, which is conducive to the test of zinc oxide arrester.

4,zero boost: The boost potentiometer starts from zero, adopts imported multi-turn potentiometer, the boosting process is stable, and the adjustment precision is high.

5,over-voltage setting: over-voltage setting uses digital dialing switch, easy to operate, and has a high setting accuracy.

6,one-piece design: the choice of integrated design, Host and double pressure cylinder is placed in a chassis. The imported high-frequency high-voltage rectifier diode is used to make the double-pressure cylinder small in size, improve the efficiency of the whole machine, and is easy to carry.

7,reliable performance: the key components use high-performance imported components, the pressure roller is coated with special insulating materials, good electrical performance, strong moisture resistance, no leakage.

8,the operation is simple: the instrument interface each function button, the layout is reasonable, the instructions are clear, easy to learn and use.
