What are the operation methods of high and low voltage switchgear power on test bench

  A high-voltage and low-voltage power on test bench developed and produced according to the power test standard
The power on test bench for high-voltage and low-voltage switchgear is mainly used by the manufacturer of high-voltage and low-voltage switchgear to carry out various power on tests before leaving the factory, and various factory index inspections have been completed The high and low voltage switchgear power on test bench can provide one or more groups of AC and DC power supplies to facilitate the detection of switchgear and improve work efficiency
The dkgg-h high and low voltage switchgear power on test bench has simple operation and high output precision, and is widely used in switchgear production units and power maintenance units
High and low voltage switchgear is a kind of electrical equipment
The external line enters the main control switch in the cabinet first, and then enters the sub control switch
Each branch circuit is set according to its needs
For example, instrument, automatic control, motor magnetic switch, various AC contactors, etc
, some are also equipped with high-voltage room and low-voltage room switch cabinet, high-voltage bus, such as power plant, etc
, and some are also equipped with low cycle load shedding for main equipment Operation method of high and low voltage switchgear power on test bench:   1
connect three-phase four wire ac380v  2
connect the output dc260v to the load   3
turn the output adjusting knob counterclockwise to the zero position 4
check and confirm that the wiring is correct   5
close the power switch   6
slowly adjust the output adjusting knob to raise the voltage to the appropriate value 7
after the power on test bench test of the switch cabinet is completed, first rotate the output adjustment knob counterclockwise to the zero position, and then disconnect the power switch
After the discharge is completed, the disconnection can be started
