According to the requirements of the "General Technical Conditions for Portable DC High Voltage Generators for Meltblown Fabric Electrostatic Generators", this newly researched, designed, and manufactured product is a high-tech product of the new era - the portable DC high voltage generator. It is suitable for DC high voltage testing of zinc oxide arresters, magnetic blow arresters, power cables, generators, transformers, switches, and other equipment in power departments, factory and mine power departments, scientific research units, railways, chemical industries, power plants, etc. It is a replacement product for the new century.It adopts a high-frequency voltage doubling circuit, takes the lead in applying new PWM high-frequency pulse width modulation technology, closed-loop adjustment, and uses large voltage feedback to greatly improve voltage stability. It uses high-performance high-power IGBT devices and their driving technology, and according to electromagnetic compatibility theory, adopts special shielding, isolation, and grounding measures. This enables the DC high voltage generator to achieve high quality and portability, and can withstand rated voltage discharge without damage.
The meltblown fabric electrostatic generatorhas added a high-precision 75% VDC-1mA function, bringing great convenience to zinc oxide arrester measurements. The control box of this instrument has a 75% voltage function key. When performing arrester tests, when the current rises to 1000uA, press the 0.75 button. At this time, the values displayed on the voltmeter and ammeter are the 75% data. After completion, immediately return the boost knob to zero, and also return the fine-tuning voltage knob to zero, then immediately press the green button to cut off the high voltage and turn off the power switch. Then proceed with other tests.
