Low-voltage capacitor-type reactive power compensation cabinet (INSVC)

The low-voltage capacitor-type reactive power compensation cabinet is a device used to compensate for the reactive power required by inductive loads. The capacitor compensation cabinet mainly consists of several components: reactive power compensation controller, capacitors, tuning reactors, dedicated contactors or thyristor switching devices, intelligent composite switches, fuses, cooling fans, and isolating switches. For industrial environments with significant harmonics, a harmonic-resistant thyristor switching capacitor cabinet should be used, while in general residential applications, an economical contactor or intelligent composite switch switching capacitor cabinet can be used. This device plays an important role in improving system power factor, enhancing power quality, extending the lifespan of electrical equipment, reducing grid transmission losses, and suppressing voltage fluctuations.
