MSGK-I ​​high and low voltage switchgear power test stand MSGK-I ​​type high and low voltage switchgear power test bench for high and low voltage switchgear manufacturers to conduct all the power test before production of high and low voltage switchgear. It can provide a variety of AC and DC power supply to facilitate the detection of switchgear and improve work efficiency.
First, technical parameters:
Input power: three-phase four-wire AC380V
Output voltage and current:
Three-phase AC0–10A output (<100V, adjustable value> One set of three-phase AC100V output (fixed value) One set of AC operating voltage output AC0~400V, 220V, current is less than 10A
DC operating voltage output DC0~260V
5, DC closing power supply output DC0 ~ 300V (rated current 100A, short-time operating current 300A) a group of 6, single-phase AC220V output (fixed value, socket form) two groups,
7. A set of three-phase AC380V output (fixed value, terminal)
8ã€Dimensions:560*520*850MM
9, Weight: 45KG
Second, MSGK-I ​​type high and low voltage switchgear electricity test bench panel schematic and line schematic 
Rear panel 
Third, MSGK-I-type high and low voltage switchgear power tester function description 1, the output line terminal string before the 10A, 16A air switch as a short circuit protection. According to the special requirements of the user, parameters 3–4 can be opened and closed at the same time without interlocking. Please pay attention to the requirements in use.
It is best to have only one set of power output work at a time.
2. The 6～7 items of 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, DC closing power output DC0-300V (large capacity) is an independent unit, can be used separately from the main cabinet, can also be used in conjunction with the main cabinet, directly from the cabinet rear panel DC 300V output terminal output. For detailed description, see the fifth: HZGK-300A switch closing power supply.
4, three-phase conversion switch K1, three-phase AC380V voltmeter,
Fourth, the operating instructions to test the single-phase AC voltage meter as an example:
Connect input power AC380V
Connect the AC operating voltage output power supply line to the voltmeter Check to see if the wiring is connected. Turn on the main power switch to return the regulator to zero, and press “Switch onâ€.
Press the switch on the AC operating voltage on the panel to slowly adjust the output adjustment knob, so that the voltage rises to the required value and observe the voltmeter.
After the test is completed, first press the "opening" twist of the AC operating voltage on the panel and then press the "opening" twist on the panel. Then, disconnect the main power switch. 5, GK-300A switch closing power, external power supply (optional according to user requirements).
The power supply consists of a fully controlled three-phase rectifier module, a phase-shift trigger circuit, an automatic adjustment circuit, and an absorption circuit.
The transistor intelligent control module integrates the complex automatic adjustment circuit, the thyristor and the trigger circuit into one, and adjusts the size of the conduction angle of the thyristor by adjusting the magnitude of the control signal voltage, thereby realizing the function of adjusting and automatically controlling the power supply.
The trigger circuit system, thyristor, and heat-conducting backplane are insulated and isolated from each other. The dielectric strength is more than 2500V, and it is safe and convenient to use. There is no phase sequence restriction at the input of the three-phase rectifier module. Applicable to resistive, load.
Instructions for use:
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 that the wiring is correct. 5. Close the power switch. 6. Slowly adjust the output adjustment knob to raise the voltage to a suitable value.
7. After the test is completed, first turn the output adjustment knob counterclockwise to zero, and then turn off the power switch. After the discharge is completed, the line can be started.
