Shunt electric reactor
Technical parameter
The shunt electric reactor is used to make compensation for the capacitive charging current in the line, limit the increase of the power frequency voltage and the operating overvoltage of the system, so the insulation level of the system can be reduced and the reliable operation of the line can be ensured. With the continuous expansion of the cities and the transformation of the urban power grids in our country, the overhead line transmission has been gradually replaced by the underground cable transmission. This has made the capacitive charging current of transmission network to increase sharply. In order to reduce the increase of the system power frequency voltage and the system insulation level, as well as to ensure the safe and reliable operation of the system and the power supply quality of the urban power grid, the shunt electric reactor, which has been widely used in the high voltage and ultra high voltage long distance transmission system, has found relatively wide applications in the urban distribution network.
