Tips: Discharging device for shunt power capacitorThe shunt power capacitor is under energy storage condition when it is put into operation. When it is disconnected from the power supply, there is still a certain amount of energy stored, and there is a certain residual voltage between the electrodes of capacitor. This energy cannot be discharged to a safe voltage in a short time by its resistance with high insulation. If the capacitor is switched to run again when there is still some charges in capacitor, a strong impact switching-on inrush current and high overvoltage will be produced, which will cause electric damage if one contacts with a capacitor that still has some residual charges , so it is necessary to equip with special discharging device.
When the capacitor is removed from power grid, perform discharging completely by discharging device. The residual charges on capacitor should be removed within prescribed period of time and make the residual voltage on capacitor reduce to specified safe voltage (75V), so as not to cause personal and equipment accident. For low-voltage capacitors, resistance in series should be adapt while the discharging coil as discharging device should be adapt for the high-voltage capacitors. Sometimes, the transformer or distribution transformer primary winding of single-phase triangular wiring or the open triangular wiring can be used as discharging coils.
