Product Description

MSGK-I Switchgear Test Bench

Darui Electric recommends:

5. GK-300A switch closing power supply, external power supply (optional according to user requirements).

This power supply consists of a fully controlled three-phase rectifier module, phase-shift trigger circuit, automatic adjustment circuit, and absorption circuit.

The transistor intelligent control module integrates the complex automatic adjustment circuit, thyristor, and trigger circuit into one unit. By adjusting the control signal voltage, it changes the thyristor conduction angle, thereby achieving the functions of power regulation and automatic control.

The trigger circuit system, thyristor, and thermal conductive base plate are mutually insulated and isolated, with a dielectric strength greater than 2500V, making it safe and convenient to use. The three-phase rectifier module input has no phase sequence restriction. It is suitable for resistive and inductive loads.

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 the appropriate value.

7. After the test, first turn the output adjustment knob counterclockwise to zero, then disconnect the power switch. After discharge is complete, you can start disconnecting the wires.

MSGK-I Switchgear Test Bench Function Description

1. Before the output wiring terminals, 10A and 16A air switches are connected in series as short-circuit protection. According to special user requirements, items 3-4 in the parameters can be closed and opened simultaneously without interlocking. Please pay attention to the requirements during use.

Only one group of power outputs can work at a time.

2. Items 6-7 in the technical parameters are not controlled by the contactor. As long as the main power switch is closed, single-phase AC220V output (fixed value) and three-phase AC380V output (fixed value) can be output.

3. The DC closing power supply output DC 0-300V (large capacity) is an independent unit that can be used separately from the main cabinet or combined with the main cabinet, outputting directly from the DC 300V output terminals on the rear panel of the cabinet. For detailed instructions, see Section 5: HZGK-300A Switch Closing Power Supply.

4. Three-phase transfer switch K1, three-phase AC380V voltmeter,

4. Operation Instructions

Taking the verification of a single-phase AC voltmeter as an example:

Connect the input power AC380V

Connect the AC operating voltage output power line to the voltmeter

Check and confirm the wiring is correct, then close the main power switch

Return the voltage regulator to zero, and press the "Close" button,

Then press the "Close" button for AC operating voltage on the panel

Slowly adjust the output adjustment knob to raise the voltage to the required value, and observe the voltmeter.

After the test, first press the "Open" button for AC operating voltage on the panel

Then press the main "Open" button on the panel. Then, disconnect the main power switch
