Overview

The ZGF series portable DC high voltage generator is a highly reliable, high-grade, and truly portable testing equipment developed in combination with China's national conditions. It is an ideal testing instrument for DC high voltage testing of zinc oxide lightning arresters, power cables, generators, transformers, switches, and other equipment in power departments, factories, mines, and power plants.

Product Details

DC high voltage generatorAdopting an intermediate frequency voltage doubling circuit, utilizing PWM intermediate frequency pulse width modulation technology, closed-loop adjustment, and adopting voltage feedback to significantly improve voltage stability. Use high-performance high-power IGBT devices and their driving technology, and adopt special shielding, isolation, and grounding measures based on electromagnetic compatibility theory. makeDC high voltage generatorIt has high quality, portability, and can withstand rated voltage discharge without damage.
The main components of the instrument are selected from advanced technologies from countries such as the United States, Germany, and Japan, making the instrument more reliable and stable. The pressure doubling cylinder has a small volume, large capacity, strong overload capacity, and is convenient for on-site operation and testing. Our company regards quality and reputation as our lifeblood, constantly improving our technological level and developing high-quality products to meet the needs of our customers.
1. On site DC high voltage testing by the power supply department, such as DC withstand voltage and leakage testing of power cables, conductivity current and 1mA reference voltage testing of magnetic blown lightning arresters and zinc oxide lightning arresters.
2. It can be used as a laser power supply and also for electrostatic spraying, electrostatic weaving, and other applications.
3. Other occasions that require high DC voltage.
4. The addition of high-precision 75% VDC-1mA function brings great convenience to the measurement of zinc oxide lightning arresters. A gentle press does not require calculation. There are 75% voltage function keys on the control box of this instrument. During the lightning arrester test, when the current rises to 1000uA, press 0.75UDC
5. All products manufactured by our company have undergone strict quality inspection, and all indicators are superior to the requirements of the power industry standard DL447.2-92 of the People's Republic of China.
