Product introduction

A DC hipot testing equipment is an electronic device used to generate a high-voltage DC electric field. The DC hipot testing equipment usually consists of a DC power supply and a transformer, and uses circuits such as rectifiers, filters, and regulators to maintain the accuracy and stability of the output voltage. The main function of a DC high-voltage generator is to generate a high-voltage electric field to drive the operation of other electronic devices

Troubleshooting

1. When the power switch is turned on, the digital display on the control box does not light up
Please check the power connection and all fuses. If the fuse is damaged, please replace it with a new one according to the amperage indicated next to the fuse seat.
2. If the power switch is turned on, the digital display will light up, the high voltage display light (green) will not light up, and high voltage cannot be applied.
① The fault display "return to zero" light is on
If there is no return to zero position, please turn the high voltage output adjustment knob and fine adjustment knob counterclockwise to return to zero position until the "return to zero" light goes out, then high voltage can be added.
② There are two phenomena when the fault display "Other" light is on: 1. Grounding protection, 2. Disconnecting protection
a. Perhaps the grounding wire is not properly connected or the grounding wire is unreliable. Please connect a reliable ground wire, turn off the power, and restart.
b. It is possible that the cable connecting the control box and the high-voltage tower is not properly connected. Please turn off the power and restart after connecting the cable. When the welding joints at both ends of the cable come loose, this fault may occur. Please weld the welding joints at both ends of the cable, turn off the power, and restart.
C. It is possible that a wire end inside the control box has detached and disconnected. Please re weld it, turn off the power, and restart.
3. Everything is normal, but it is protected during the process of not reaching the rated output voltage
① The fault display "overcurrent" light is on
a. Short circuit or excessive leakage current of the test sample.
b. When there is a large capacitive load, the boost is too fast. Turn off the power, restart, and slow down the boost speed.
② The fault display shows that the "overvoltage" light is on
The overvoltage protection setting knob is not placed at the maximum position. Please rotate it clockwise to the maximum position, turn off the power, and restart.
4. When a short circuit occurs under high voltage of the test sample, due to the large short-circuit current, it is possible to turn on all the fault display lights, which is normal. Please troubleshoot the test sample and restart.
5. After troubleshooting the sample, the fault display light still lights up and high voltage cannot be applied.
The power switch also serves as a fault protection reset switch. Please turn off the power switch and restart it to boost the voltage.
6. If you notice significant fluctuations in the voltmeter readings, please check if the 7-pin shielded mesh head and center shielded wire head of the aviation plug at both ends of the connecting cable have come loose or disconnected. If they are disconnected, please weld them properly.
