High voltage direct current withstand voltage test discharge method

The invention relates to a high voltage direct current withstand voltage test discharge method. The method comprises the steps that a discharge device and tested electrical equipment are provided, firstly parameters of a direct current withstand voltage test of the tested electrical equipment are collected, and discharge time t when the test voltage of the tested electrical equipment is lowered to1000V is calculated; then the discharge device is assembled, adjusted and subjected to simulation operation, a sliding trolley is controlled by an operating lever to move, so that a discharge guide rod is in contact with the tested electrical equipment, and discharge is performed through a discharge resistor; finally discharge current is monitored through a discharge current detection module, thedischarge current reaches a preset value by adjusting the discharge resistance values, and when the discharge current is 0, discharge of the tested electrical equipment is ended. The high voltage direct current withstand volt
