1 High voltage output: dedicated DC high voltage output terminal.
2 High-voltage grounding column: Also known as high-voltage tail, it must be grounded separately and reliably to prevent high-voltage leakage and discharge. Poor contact may cause failure to boost the voltage, high voltage breakdown of the internal components of the instrument, and safety accidents caused by leakage or discharge inside the instrument.
3 Voltmeter: high voltage output voltage indication, used to display the output voltage value.
4 Power socket: the working power of the instrument, AC 220V/60Hz.
5 Fuse socket: the place where the fuse of the AC 220V power supply system is installed.
6 Power switch: "I gear" Use AC 220V power supply to supply power to the system, the power light will be on when it is turned on, and the power light will be off when the "0 gear" is turned off.
7 Start button: When the start button light is on, it means that the voltage output is in the zero position. The start button is valid when it is on. If the start button light is not on after turning on the power switch, adjust the voltage adjustment knob counterclockwise until the light is on. When the start button light is on , press this key to start the device and generate high voltage output.
8 Stop button: When the test is completed or there is an abnormality, press this button to cut off the high voltage output.
9 Voltage adjustment knob: Before starting the device, you must turn this knob counterclockwise to zero, then adjust clockwise to increase the output high voltage from small to large, and adjust counterclockwise to decrease the output high voltage from large to small.
10 Ammeter: Indication of low-voltage side current.
11 Safety grounding column: the ground of the instrument shell, in order to prevent the instrument shell from being electrified or people getting electric shock, it must be connected to the ground reliably.

Application:
DC high-voltage power supply can be widely used for cable fault detection of 35kV and below
Wiring introduction
Steps
1 Check the wiring according to the wiring diagram to ensure that all ground wires are in good contact (the distance between the ball gap is 1mm and the discharge voltage is about 3kV, and the ball gap can be adjusted from small to large on site).
2 Check whether all ground wires, the high-voltage output wire from the host to the capacitor terminal and the high-voltage output wire from the capacitor terminal to the DUT are in good contact. After the inspection is complete, turn on the AC 220V power supply.
3 Turn on the "power switch", press the first gear when the AC 220V power supply is turned on, then the switch light is on, and the AC 220V power supply is normal.
4 When the "start button (zero position light)" light is on, press the "start button" to start the high voltage. If the "start button (zero position light)" light is not on, adjust the "voltage adjustment knob" to the zero position counterclockwise to ensure that the "voltage adjustment knob" is in zero state, at this time the "start button (zero position light)" light is on; Restart the high voltage output again.
5 When the high voltage starts normally, the "stop button light" is on to indicate that there is high voltage output. At this time, slowly adjust the "voltage adjustment knob" clockwise, observe the "voltmeter" indication, and adjust to the required discharge voltage or DC withstand voltage value. .
6 When the discharge interval is too fast: you can adjust the "voltage adjustment knob" counterclockwise to reduce the output high voltage frequency; when the discharge interval is too slow: you can adjust the "voltage adjustment knob" clockwise to increase the output high voltage frequency, and then adjust the "voltage adjustment knob" again. "Let the discharge interval reach the required time (generally 4-8S is recommended).
7 After the fault test or DC withstand voltage test is completed, adjust the "voltage adjustment knob" counterclockwise to the zero position to ensure that the "voltage adjustment knob" is in the zero position state. At this time, the "start button (zero position light)" light is on.
8 After the "start button (zero position light)" light is on, press the "stop button" to cut off the high-voltage output; at this time, use a special discharge rod to correctly and fully discharge the high-voltage end of the capacitor and the object under test (first use arc discharge, and then use direct Discharge), observe the change of "voltmeter" during discharge, when the "voltmeter" indicates "zero", it means the discharge is completed.
9 Finally, turn off the power switch; put away all test leads.
