1. The layout of the testing equipment should have sufficient safety distance around the human body. Try to avoid placing equipment and high-voltage leads in personnel corridors.
2. Install fences and hang "Stop, High Voltage Danger" signs on the test site.
3. During the experiment, the high-voltage lead should have support or traction insulation. There should be a safety supervisor to prevent anyone from approaching or passing through from below.
4. In the DC high-voltage test, it is best to have the microampere meter in the high position. In addition to the shielding box, there is an overcurrent automatic protection device to prevent the meter from burning out in case of sudden breakdown, short circuit or discharge.
5. Power frequency withstand voltage test: Please pay attention to checking whether the equipment capacity is sufficient and avoid resonance.
6. The working ground wire (high-voltage tail, voltage stabilizing capacitor end ground wire) and the protective ground wire (control box shell) should be connected separately and have good grounding performance.
7. If there is an irregular swing of the power supply during the experiment (such as welding), it will inevitably affect the stability of the high-voltage output. At this time, the experiment should be stopped to find the cause and eliminate it.
8. The requirements for climate (temperature, humidity) in the testing work should comply with the requirements of the testing regulations and be recorded.
9. High voltage testing work must strictly comply with the relevant provisions of the safety work regulations issued by the Ministry of Energy.
