The high-voltage harmonic filter is specially used for harmonic passive filter devices for 3, 5, 7, 11, 13 and above times in high-voltage power grid. It is suitable for medium frequency furnace, electric arc furnace, rolling mill, rectification equipment and other places with large harmonic generation. The filter adopts a series resonant absorption loop composed of a filter reactor and a filter capacitor to absorb harmonics effectively, so the harmonic current is prevented from returning to the power transformer to enter the power grid, the harmonic amount of the power grid is greatly reduced, meanwhile, it is beneficial to the operation of the power transformer of users, the power consumption is reduced, and the reliability of equipment and other electrical components is improved. In addition, the equipment also provides reactive power compensation with a certain capacity to improve the operation efficiency of user load. Each set of device is designed according to the customer's requirements, and it must ensure that the best harmonic filtering performance and reactive compensation can be reached, the efficiency of the user load is improved, and the effective investment return is achieved.

It is composed of several groups of FC single tuned harmonics and high-pass filter branches, and each group is composed of a filter capacitor and a reactor. The characteristic harmonics is effectively absorbed to achieve the purpose of reducing system harmonics effectively.
