Abstract

The utility model discloses a high-voltage parallel capacitor which comprises a capacitor case housing and lead-out bushings. Multiple groups of capacitor units are disposed in the capacitor case housing. The lead-out bushings are disposed at top ends of the capacitor box housing. The top of each lead-out bushing is provided with a wiring terminal for connecting a high-voltage circuit. The capacitor units are connected in parallel with each other and are connected with the bottoms of the lead-out bushings through discharge resistors. Each capacitor unit includes a capacitor and a protective fuse, wherein the protective fuse is connected in parallel with the capacitor. Since each parallel capacitor unit inside the high-voltage parallel capacitor is connected with a protective fuse in an I-shaped structure, a capacitor unit where a fault point is located can be rapidly cut off, and other capacitor units with no faults can work normally. Therefore, the high-voltage parallel capacitor is safe and reliable and is simple and compact in structure, convenient to install and use, and has a long service life and good application prospects.
