High Voltage Rectifier Silicon Reactor Using 2DL-150kV/100mA

The protective resistance of high voltage rectifier silicon stack is wrapped on insulating cylinder by enameled resistance wire.

Constant Current and Double Voltage Charging Method

The charging device can be adjusted within the rated charging voltage range of 30%-100%. The deviation between the actual charging voltage and the measured voltage is not more than (+) 1%, and the instability of the charging voltage is not more than (+) 1%.

DC resistor divider adopts 100 kV, 100 MW oil-immersed metal film resistor. The resistance of the low-voltage arm is installed in the bottom flange of the divider, and the voltage signal on the low-voltage arm is introduced into the console by a shielded cable.

The automatic grounding switch adopts the electromagnet dividing and closing grounding mechanism. When the test stops, the main capacitor can be grounded automatically through the protective resistance.
