10KV High Voltage Shunt Capacitor 200kvar - Power Capacitor - Capacitor Bank
1. Overview of 10KV High Voltage Shunt Capacitor 200kvar - Power Capacitor - Capacitor Bank
Medium voltage shunt capacitor/High voltage shunt capacitor is composed of a pack, a case, outlet porcelain busing, etc. The two sides of stainless steel case are welded with hanging brackets for installation, and one hanging bracket is equipped with a grounding bolt. In order to adapt to various voltages, the pack is composed of several small elements connected in parallel and series. The capacitor is equipped with a discharge resistor.
2. Function of 10KV High Voltage Shunt Capacitor 200kvar - Power Capacitor - Capacitor Bank
Medium voltage shunt capacitor/High voltage shunt capacitor are suitable for 50Hz or 60Hz AC power systems to improve the power factor of the power system, reduce line losses, improve the quality of the power supply voltage, and increase the active output of the transformer.
The Shunt Capacitor is suitable for the power system of power frequency (50 or 60Hz) , to increase the power factor , reduce line loss , improve voltage quality .
When capcitor bank put into use , the ambient temperature shall not be lower than -50℃, and sverage temperature not exceeding +55℃, not exceed +20℃ per a year . if out of this range , fan shall be used to cool or switch off the capacitor bank.
when the load in network is small , after connected with capacitors, the system voltage will rise up , if the voltage between terminals of cpacitor exceeds 1.1 times of rated voltage , it shall switch off partial or all capacitors for protecting capacitors safe operation.
During in sevice or transportation , if capacitor leak oil , it can be processed by use of Tin and PB material brazing .
