High and low voltage switchgear power test bench can provide one or more groups of AC, DC power supply, easy to test the switchgear, improve work efficiency, high and low voltage switchgear power test bench simple operation and high output accuracy, widely used in switchgear production units and power maintenance units. High and low voltage switchgear is a kind of electrical equipment, the outside line first enters the main control switch in the cabinet, and then enters the branch control switch, and each branch is set according to its needs. Such as instruments, automatic control, motor magnetic switches, various AC contactors, etc., some also have high voltage chamber and low voltage chamber switchgear, with high voltage bus, such as power plants, etc., and some also have low cycle load reduction for the main equipment.
High and low voltage switchgear power test bench operation method:
1. Connect the three-phase four-wire AC380V
2. Connect the output DC260V to the load
3. Turn the output adjustment twist counterclockwise to zero.
4. Verify that the cables are correctly connected
5. Turn on the power switch
6. Slowly adjust the output adjustment twist to raise the voltage to the appropriate value.
7. After the switch cabinet power test bench test is completed, first turn the output adjustment twist counterclockwise to zero, and then turn off the power switch. After the discharge is completed, the wire can be unwound.
