KGC high-voltage shunt capacitor set is the most widely used reactive power compensation/filtering device at present. It is generally composed of shunt capacitor bank, series reactor, vacuum contactor, disconnector, controller, arrester, discharge coil, protection measurement and other equipment, as shown in the figure. The equipment is mainly used in three-phase AC power systems of 6kV, 10kV, 35kV, 110kV and other voltage levels.
The capacitor bank mainly provides sufficient reactive power; The series reactor bank mainly limits the inrush current during capacitor switching, and absorbs a harmonic current of the system at the same time; The vacuum contactor realizes the switching of capacitor bank; The disconnecting switch is used as the electrical disconnection point for maintenance; The controller controls the contactor according to the set control objectives (voltage, power factor, reactive power); Arresters protect capacitor devices from the threat of switching overvoltage; The discharge coil is mainly used to release the charge at both ends of the capacitor bank within a short time after the capacitor is out of operation, so as to avoid dangerous overvoltage during the process of putting the capacitor into operation again; The common protection of capacitor is generally set with overcurrent, overvoltage, undervoltage, imbalance, etc.
