4.9KV 573 kVar Capacitor Bank High Voltage 50Hz Rated Frequency
1. Overview of 4.9KV 573kVar High Voltage Shunt Capacitor
High-voltage shunt capacitors are used to compensate for reactive power in the AC power system of 1000 V above voltage, frequency 50Hz or 60Hz,improve power factor, reduce line loss and saving energy,improve the quality of the power supply. The product performance conforms to GB/T 11024-2001, the standard requirement of the series standard for the use of parallel capacitor for AC power system with AC power system of 1kV above voltage.(GB/T 11024—2001 same as IEC 60871—1997).
2. Function of 4.9KV 573kVar 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.
