How to correctly replace the high-voltage power distribution cabinet compensation cabinet fuse

First of all, you should confirm that the cabinet switch in the state of excision, and then disconnect the cabinet's main power switch, for capacitor cabinets and then disconnect the capacitor power supply to let the capacitor self-discharge 6 ~ 8 minutes, and then use a special discharge rod on the capacitor to the ground discharge not less than 2 minutes. If you can't confirm the residual voltage of the capacitor after self-discharge, you should connect a current limiting resistor between the discharge rod and the ground and then discharge the capacitor. After the discharge before you can contact the capacitor to replace the fuse.
