Common faults of the DC high voltage generator: Fault 1. Turn on the power switch of the DC high voltage generator, and the power indicator and the green light are not on?

Failure analysis: check the power fuse, power cord and power switch;

Solution: If any one of them is damaged, please replace it in time.

Fault 2. After turning on the power switch of the DC high-voltage generator, the power indicator flashes green and is accompanied by a buzzer sound.

Fault analysis: A is not grounded; B is grounded unreliable; C uses the generator power supply or the power supply through the switchgear isolation transformer.

Solution: A ground; B check whether the grounding wire is reliable and re-ground; C if the power supply is changed by 1/1 isolation or a spontaneous power supply is used on site, the power supply must be artificially connected to the ground.

Trouble 3. After turning on the power switch of the DC high-voltage generator, the green light of the power indicator is on, and the red light of the high-voltage indicator is off (the high-voltage cannot be closed).

Failure analysis: A voltage regulator is not in the zero position; B overvoltage setting switch is set to zero; C high pressure indicator button light may be damaged.

Solution: A. Return the potentiometer to the zero position. B. Set the overvoltage setting switch to the voltage value required for this test. C Check the high-voltage indicator light if it is damaged, please replace it.

Fault 4. The indication of the high-voltage digital micro-ammeter is always zero during the use of the DC high-voltage generator.

Failure analysis: A high-voltage digital microammeter may be damaged, B microammeter output line may be short-circuited, C microammeter output line is poorly connected.

Solution: A. Return the microammeter to the factory for repair. B Check the microammeter output line. If there is a short circuit, please re-solder. C Check the microammeter output line and the microammeter contact power switch. If there is any damage, please replace it in time.
