1. The equipment is mainly composed of high-voltage test transformer, contact regulator, servo speed control system, acquisition system, control system, automatic discharge and other parts.
2. The test transformer input is given by the voltage regulator output, and the high voltage output is collected in real time by the acquisition system. The computer adjusts and controls the speed regulation system of the voltage regulator rotation according to the voltage, forming a closed loop and making the voltage regulation process smoother. And can meet the requirements of slow voltage boost.
3. Automatically distinguish AC-DC test process. If the DC test is carried out, the discharge operation can be automatically carried out at the end of the test, during the period (in the case of no discharge) to open the test cabin door, there will be sound and light alarm, warning danger!

1. Overcurrent protection:
1.1 Low voltage side current protection to protect the safe operation of high voltage transformer
1.2 High voltage side current protection to protect the electrode surface from electrical spark corrosion
1.3 If the preset leakage current is exceeded, cut off the high voltage output
2. High voltage power off protection:
2.1 Over range automatically cut off the high voltage output
2.2 The high voltage output can be turned off manually during the experiment
2.3 If the voltage drop exceeds the preset value, cut off the high voltage output
3. Output zero protection:
3.1 Before the experiment starts, if the high voltage output is not in zero position, give a prompt
3.2 If the high voltage output is not in the zero position, forcibly return to zero
4. Short circuit protection:
4.1 High voltage output short circuit, automatically cut off the output
4.2 Low voltage input short circuit, automatic power off 5. Safety door protection:
5.1 When the hatch door is unintentionally opened during the experiment, the output is automatically cut off
5.2 The test cannot be started when the test cabin door is open
5.3 After the end of the experiment, open the cabin door and cut off the high voltage output.
Ask for confirmation before starting each experiment. Otherwise pop-up window
6.1 When the high voltage readiness switch is pressed, the high voltage indicator is on
6.2 The test cabin door is closed
6.3 Voltage Regulator Reset (High Voltage output is zero)
7. Discharge protection:
7.1 After the DC test, the sound and light alarm is given when the hatch door is opened, and the discharge of the pressure equalizing ball is mandatory
8. Leakage protection:
8.1 Independent grounding protection
8.2 Leakage protection switch
