3.81KV 425 kVar Capacitor Bank High Voltage 50Hz Rated Frequency
1. Overview of 3.81KV 425kVar High Voltage Shunt Capacitor
High voltage shunt capacitor (Power capacitor) is mainly used in the A.C,Power system with 50Hz or 60Hz to improve power factor, reduce reactive power loss, mend voltage quality, plenitude elaborate generate power' equipment and supply power equipment efficiency, it is national recommend save power products.
2. Function of 3.81KV 425kVar 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.

3. Main features of 3.81KV 425kVar High Voltage Shunt Capacitor
1. Capacitor made of shell and core, shell body constructed of thick steel sheet being soldiered. Outgoing porcelain bushing welded and passed through
top cover of capacitor, two sides of shell provided with two lifting brackets, one of lifting bracket assembled with earthing bolt.
2. Capacitor core has several elements and insulated parts to be stacked. It uses Polypropylene film as medium and Al foil as polar plate to be rolled.
3. In order to work in different voltage rating, the elements in core will be connected in series or parallel. As required, the discharging resistance can be built-in.
4. Applicable standard of 3.81KV 425kVar High Voltage Shunt Capacitor
IEC60871 and equivalent standard
5. Working conditions of 3.81KV 425kVar High Voltage Shunt Capacitor
1, Altitude:Less 1000m;Ambicnt Temperature:-40℃ to 40℃.
2, No violcnt mcchanical vibration, no harmful gas and vapor ,no electric,and cxplosive dust in location.
3‚ Power capacitor will work in the good ventilate condition, it would not permit to work in sealing and no ventilate condition.
4‚ Power capacitor connection wire should take soft conductive wire, the whole circuit connect well.
