1. Overview of 8.25KV 620kVar High Voltage Shunt Capacitor 

High-voltage capacitors are mainly composed of lead-out porcelain bushings, capacitive element groups and shells. The shell is sealed and welded by thin steel plates, and the outlet porcelain sleeve is welded on the shell. The wiring terminal is led out from the outlet porcelain bushing. The capacitor element group (also called the core) in the shell is formed by connecting several capacitor elements. The capacitive element is made of capacitor paper, film-paper composite or pure film as the working medium, and aluminum platinum as the pole plate. In order to meet the withstand voltage requirements of capacitors of various voltage levels, capacitive elements can be connected in series or in parallel. The electric passenger component group of a single three-phase capacitor is connected into a triangle inside the shell. In high-voltage capacitors with a voltage of 10kV and below, each capacitive element is connected in series with a fuse, which serves as the internal short-circuit protection of the capacitor. Some capacitors are equipped with discharge resistance. When the capacitor is disconnected from the grid, it can be discharged through the discharge resistance. Generally, the residual voltage of the capacitor can be reduced to below 75V after 10 minutes.

2. Function of 8.25KV 620kVar High Voltage Shunt Capacitor

       High voltage parallel capacitor is composed mainly of the packet, shell and insulation porcelain, the packet is connected in a particular way by dozens of components, separated by insulation and wrapped. The shell is welded with thin steel plate (or stainless steel plate),the two sides of the wall have the bracket for welding and installing. The lid of box is covered with (or embedded pressure assembly) line casing,components are made of polypropylene film and aluminum foil,and the capacitor is filled with excellent electrical insulation liquid impregnant.
