The KDGK-II 35kV high and low voltage switchgear power test bench can provide various AC and DC power sources for testing the switchgear.

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

The transistor intelligent control module integrates complex automatic adjustment circuits, thyristors, and trigger circuits into one. By adjusting the voltage of the control signal and changing the conduction angle of the thyristor, it achieves the function of regulating and automatically controlling the power supply.

The triggering circuit system, thyristor, and thermal conductive substrate are insulated and isolated from each other, with a dielectric strength greater than 2500V, making it safe and convenient to use. There is no phase sequence restriction at the input end of the three-phase rectification module. Suitable for resistive and inductive loads.
