Adopt HV silicon stack ZCL-400kV/0.1A, silicon stack protection resistor: 200kV 5kΩMain circuit structure, this system is designed as unilateral unsymmetrical single stage voltage-multiplying circuit, besides test transformer, voltage regulator, the filter capacitor, multi-voltage 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 polarity reverses. The top electrode (corona ring) is special designed for DC generator. See outside drawing. There is safety earthing system on the generator, which protects the safety of staff and equipment. The HV DC Generator will be equipped on movable basement, with wheels. The DC Divider together with the DC Generator on the same basement. This will save the space in Maximum. When loading the object, the DC system can be move aside.
