Electric Power Level 5 Qualification DC High Voltage Generator
Security Warning:
The experimenters of the DC high voltage tester must be professionals with a "high voltage testing certificate"
Users must follow the provisions of Article 168 of the "Electricity Safety Regulations" when using this instrument, and install two obvious disconnection points before the working power supply enters the tester
When the DC high voltage is 200KV or above, although the test personnel wear insulated shoes and are at a safe distance, the distribution of high-voltage DC ions can cause different DC potentials on nearby people. Test personnel should not shake hands with each other or touch the grounding body with their hands, otherwise there may be slight electric shock, which generally does not cause harm to people. Cable testing must use current limiting resistors.
When discharging a large capacitor test sample, the discharge rod should not be immediately in contact with the test sample. Instead, the discharge rod should be gradually brought closer to the test sample until it reaches a certain distance and begins to discharge freely with a hissing sound in the air gap. When there is no sound, a discharge rod can be used to discharge, and then the ground wire can be directly grounded for discharge.
Product Introduction:
Suitable for power departments, power departments of factories and mines, scientific research institutions, railways, chemical industries, power plants, and other equipment for DC high voltage testing of zinc oxide lightning arresters, magnetic blow lightning arresters, power cables, generators, transformers, switches, and other equipment.
Adopting high-frequency voltage doubling circuit, applying PWM high-frequency pulse width modulation technology, closed-loop adjustment, and adopting voltage feedback, the voltage stability is greatly improved. Using high-power IGBT devices and their driving technology, and based on electromagnetic compatibility theory, adopting special shielding, isolation, and grounding measures. The DC high-voltage generator achieves high quality, portability, and can withstand rated voltage discharge without damage. ⑴ Make the ripple coefficient smaller; ⑵ A high-precision 0.75UDC-1mA function button has been added, which brings great convenience to the zinc oxide lightning arrester tester The high-voltage overvoltage setting adopts a digital dial switch, which can intuitively display the set voltage value and has high setting accuracy ⑷ The output voltage regulation adopts a single multi turn potentiometer, which ensures a smooth boosting process, high adjustment accuracy, and simple operation. The product uses a low-voltage microcurrent grounding protection circuit to protect the safety of the test personnel.
