Low-Voltage Switchgear Power-On Test Bench |
Operating Instructions:
1. Connect the input power supply AC380V
2. Connect the AC operating voltage output power cord to the voltmeter
3. Check and confirm whether the wiring is correct, then 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 operating 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 is completed, first press the "Open" button for AC operating voltage on the panel, then press the main "Open" button on the panel. Then, turn off the main power switch
Testing Method:
For the switchgear power-on test bench factory direct sales, first connect the wire on the test bench to the wire on the secondary side of the current transformer of the switchgear, press the closing button of the main circuit control, at this time the closing light is on, then press the closing button of the three-phase current control, at this time the closing light of the three-phase current control is on, and then the three-phase current in the rear outlet board will have current output. If the required current is 10A, just adjust the voltage regulator to make the output current 10A. The operation method for the other two channels is the same. The fixed output on the rear outlet board means that the output voltage is a fixed value. As long as the input voltage remains unchanged, the output voltage will not change. There are three fuses inside the equipment. If after plugging in the main power supply, the voltmeter has no display or an overload occurs, it may be that the fuse is blown. Just replace it with the same specification. However, replacing with a larger fuse is very dangerous, which will cause damage to the equipment. After the test is completed, first turn the output adjustment knob counterclockwise to zero, then disconnect the power switch, and after the discharge is completed, can you start to disconnect the wires
