Oil-immerse Shunt Reactor

BKS oil-immerse shunt reactor is used to compensate the capacitive charging current of the line, limit the rise of the system power frequency voltage and the operating overvoltage, thus reducing the insulation level of the system and ensuring the reliable operation of the line. With the continuous expansion of China's urban scale and the transformation of the urban power grid, the overhead line transmission is gradually replaced by the underground cable transmission, making the capacitive charging current to the ground of the transmission network increase sharply. In order to reduce the rise of the system power frequency voltage and the system insulation level, ensure the safe and reliable operation of the system and the quality of the urban power grid power supply Shunt reactors widely used in long-distance transmission systems are widely used in urban distribution networks.
