Portable high voltage generator steps, you know?

1. The integrity of the tester should be checked before use. There should be no open circuit and short circuit in the connection cable, and no damage to the device.

2. Put the chassis and double pressure tube in proper position and connect the cable, grounding wire and power cord respectively. The protective grounding wire and the working grounding wire and the discharge rod grounding wire should be separately received from the ground of the sample. One point is grounded). It is forbidden to connect each grounding line in series. For this purpose, a dedicated SDZF grounding wire should be used.

3, the power switch is placed in the off position and check the regulator position should be zero. The overvoltage protection setting is generally 1.1 times the test voltage.

4, no-load booster verification over-voltage protection setting is sensitive.

5. Turn on the power switch. At this time, the green light indicates that the power is on.

6, press the red button, the red light, that high pressure connected.

7. Adjust the regulating positioner clockwise gently. The output terminal starts boosting from zero and rises to the required voltage. The portable high voltage generator records the ammeter reading according to the specified time and checks the control box and the high voltage output line for abnormalities. Phenomenon and sound.

8, step down, will adjust the piezoelectric back to zero, then press the green button, cut off the high voltage and turn off the power switch.

9. Leak test and DC voltage withstand test on the test sample. After the inspection test is conducted to confirm that there is no abnormality in the tester, the leakage of the test sample and the DC withstand voltage test can be started. Connect the test sample, ground wire, etc., and turn on the power after checking.

10. Boost to the desired voltage or current. The boost rate is preferably 35KV per second. Portable high-voltage generators need to monitor the charging current of the ammeter when the voltage of the large-capacitance sample increases. The charging current of the ammeter must not exceed the maximum charging current of the tester. For small capacitor samples such as zinc oxide surge arresters, magnetic discharge arresters, etc., first rise to 95% of the required voltage (power supply), then slowly and carefully rise to the required voltage (current), and then read the voltage from the digital meter ( Current value. If you want to measure the 0.75UDC1mA of the zinc oxide surge arrester, first increase the UDC to 1mA voltage value, then press the yellow button, then the voltage will be reduced to 75% and maintain this state. At this point you can read the ammeter. After the measurement is completed, adjust the piezo-resistor back to zero by pressing the green button. Press the red button when you need to boost it again. If necessary, use an external high voltage divider to compare the DC high voltage indication on the control box.

11, after the test, step down, turn off the power.
