Parameters of DC high-voltage generator

Product Introduction:

DC high-voltage generators are suitable for measuring the conductivity current of high-voltage zinc oxide lightning arresters, magnetic blow lightning arresters, DC withstand voltage tests of power cables, DC withstand voltage tests of large capacity generator sets, and other occasions requiring DC high-voltage power supply in power departments, power departments, railways, chemical industries, power plants, etc.

High frequency voltage doubling circuit is adopted, advanced PWM high-frequency pulse width modulation technology is applied, closed-loop adjustment is adopted, and voltage feedback is used to greatly improve voltage stability. Use high-performance high-power IGBT devices and driving technology, and adopt special shielding, isolation, and grounding measures based on electromagnetic compatibility theory. The DC high-voltage generator achieves high quality, portability, and can withstand rated voltage discharge without damage. It has the characteristics of high output power and small size, reliable overvoltage, overcurrent, and zero position closing protection functions, and has a 0.75 times voltage switching function. It is mainly suitable for power departments, industrial and mining, metallurgy, steel and other enterprises to conduct DC withstand voltage tests or DC leakage current tests on high-voltage electrical equipment such as zinc oxide lightning arresters, power cables, transformers, circuit breakers, generators, etc.

Notes:
1. To ensure personal safety, we repeatedly remind users to pay attention to the good grounding of the control box and high-voltage tower, as well as the discharge issues of the test samples and high-voltage tower after shutdown.
2. Please do not cover the upper and lower ventilation holes of the control box, and prevent foreign objects from falling into the holes. If there is a fan in the control box, it should be checked regularly to ensure that the fan is running properly.
3. When the insulation cylinder of the high-voltage tower is dirty, please wipe it clean with a dry cloth, and do not use organic solvents such as alcohol and gasoline for scrubbing. Clean the surface of the insulation cylinder with detergent and wait for it to air dry before use. Please place it in an aluminum alloy box during transportation or when not in use.
4. When replacing the fuse, please replace the fuse according to the rated amperage next to the fuse seat.
5. If the high voltage shielded microampere meter displays' LOW BAT ', please replace the 9V battery to avoid measurement errors. When not in use, please turn off the power.
6. Do not open the control box and high-pressure tower without permission, as this will affect the warranty of the product. The manufacturer is not responsible for disassembling on their own.
