Transformer High and Low Voltage Switchgear Power-on Test Bench Usage Instructions
1. Connect three-phase four-wire AC380V
2. Connect the output DC300V to the load
3. Turn the output adjustment knob counterclockwise to zero.
4. Check and confirm the wiring is correct
5. Close the power switch
6. Slowly adjust the output adjustment knob to raise the voltage to a suitable value.
Operating Instructions:
1. Connect the input power supply AC380V
2. Connect the AC operation voltage output power line to the voltmeter
3. Check and confirm the wiring is correct, turn on the main power switch 4. Return the voltage regulator to zero, and press the "Close" button,
5. Then press the "Close" button for AC operation voltage on the panel
6. Slowly adjust the output adjustment knob to raise the voltage to the required value, and observe the voltmeter.
7. After the test, first press the "Open" button for AC operation voltage on the panel, then press the main "Open" button on the panel. Then, turn off the main power switch
