Neutral Point Harmonic Eliminator

LXQ (LXQ3, LXQ4) type nonlinear resistance harmonic eliminator (harmonic eliminator for short) for neutral point of voltage transformer is installed in primary winding (or secondary winding) Y of 6~35kV voltage transformer (PT for short). A nonlinear resistance harmonic damping device between the neutral point of the junction line and the ground. Compared with the traditional RXQ type harmonic eliminator, the LXQ type harmonic eliminator has been greatly improved in design to improve the thermal capacity of the harmonic eliminator. The harmonic eliminator has superior electrical performance. The ultra-fine particle Sic is used as the base material. It is formed into high-density reducer by large tonnage hydraulic mechanism and fired at high temperature of thousands of degrees under reducing atmosphere. The exposed resistor surface structure has been specially treated to prevent rain (one of the main indicators of the Sic harmonic eliminator is that the cold water cannot explode after action), and can be directly used outdoors. The new LXQ (LXQ3, LXQ4) harmonic eliminator is favored by users because of its small size, light weight, high strength, fast heat dissipation, and removal of the porcelain shell of the traditional PXQ harmonic eliminator, making it easier to install. The production of products shall comply with international GB/T16927 and enterprise standard Q/NM.J-2005
