MSGK-I Switchgear Power-on Test Bench is used by high and low voltage switchgear manufacturers to conduct various power-on tests before delivery. It can provide various AC and DC power supplies, facilitating the testing of switchgear and improving work efficiency.
I. Technical Parameters:
Input Power: Three-phase four-wire AC380V
Output Voltage and Current:
Three-phase AC 0 – 10A output (<100V, adjustable) one group
Three-phase AC100V output (fixed value) one group
AC operation voltage output AC 0~400V, at 220V, current less than 10A
DC operation voltage output DC 0~260V
5. DC closing power supply output DC 0~300V (rated current 100A, short-time working current 300A) one group
6. Single-phase AC220V output (fixed value, socket form) two groups,
7. Three-phase AC380V output (fixed value, terminal) one group,

III.Function Description
1. Before the output terminal, 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 interlock. Please pay attention to the requirements during use.
Only one group of power output 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, directly outputting from the DC 300V output terminal on the rear panel of the cabinet. For detailed instructions, see V: HZGK-300A Switch Closing Power Supply.
4. Three-phase transfer switch K1, three-phase AC380V voltmeter,
