High voltage generator without high voltage output
What is the reason why the generator has no high voltage output during the test of the DC high voltage generator? Investigate the reason: The distilled water in the high-pressure water resistance will dry up due to long-term storage. Once such things happen, the generator will have no high-voltage output.
DC high-voltage generators have a common defect, which is equipped with a built-in current-limiting resistor (actually a built-in water resistance) in the press cylinder. After the DC high voltage generator is used for a period of time, the distilled water in the built-in water resistance will dry up. Once such things happen, it will cause the generator to have no high voltage output.
Solution:
1. Refill distilled water into the high-pressure water resistance;
2. Remove and short-circuit the original one, and install an external current-limiting resistor to solve this type of failure.
safety warning
● The staff using the DC high voltage tester must be a professional with a “high voltage test certificate”.
● To use this instrument, the user must follow Article 168 of the "Electric Safety Regulations" and install two obvious disconnect points before the working power supply enters the tester; when replacing the test product and wiring, the two power disconnect points should be disconnected first Obviously disconnected.
● Before the test, please check whether the grounding wire of the tester control box, the pressure doubler and the test product are well connected.
In the high-voltage power test, DC high-voltage generators are widely used. Please read the instructions carefully before operating!
