Main circuit structure, this system is designed as unilateral unsymmetrical single stage voltage-multiplying circuit, besides test transformer, voltage regulator, the filter capacitor, multivoltage capacitor, silicon rectify stack is placed separately on three basement. The resistance voltage divider and earthing switch has the same basement which equip universal wheel and lifting jack. We can customize movable and stable type. Manual change polarity. The top electrode(corona ring) is special designed for DC generator. See outside drawing. There are safety earthing system on the generator, which protects the safety of staff and equipment.
