High voltage harmonic filter is used for 3 times, 5 times, 7 times, 11 times, 13 times and more harmonic passive filter devices in high voltage power network.It is suitable for medium frequency furnace, electric arc furnace, rolling mill, rectifier equipment and other places where harmonic generation is large.
High voltage harmonic filter is used for 3 times, 5 times, 7 times, 11 times, 13 times and more harmonic passive filter devices in high voltage power network.It is suitable for medium frequency furnace, electric arc furnace, rolling mill, rectifier equipment and other places where harmonic generation is large.Filter USES the filter reactor and a filter capacitor series resonance absorption circuit, effective harmonic would be absorbed, so as to avoid the harmonic current to return to power transformer into the power grid, reduce the harmonic content of the grid, is advantageous to the user at the same time the operation of the power transformer, reducing power consumption, improve the reliability of equipment and other electrical components.In addition, the device also provides a certain capacity of reactive power compensation to improve the operation efficiency of user load.Each unit is designed to meet customer requirements and ensure harmonic filtering performance and reactive power compensation, improve the efficiency of user load, and achieve effective return on investment.
It is composed of several groups of FC monotonic harmonic and high-pass filtering branches, and each group is composed of a filtering capacitor and a reactor.It can effectively absorb characteristic harmonics and reduce system harmonics effectively.
