Picture show Explanation
LXQ3 type voltage transformer neutral point with nonlinear resistors harmonic elimination damper (SR-off resonance eliminator) is installed in the 6-35kV voltage transformer (referred to as PT) a winding (or secondary winding) Y. Tie line between neutral and ground resistance of a one hundred linear damped harmonic elimination device. And traditional RXQ harmonic elimination compared, LXQ harmonic elimination harmonic elimination from the increased heat capacity of departure in the design of a larger improvement. Harmonic elimination uses electrical Kong students grade superior, ultrafine particles SIC as the base material, the large-tonnage hydraulic machine pressed into high-density body, in a reducing atmosphere by thousands of degrees high temperature sintering. Exposed surface of the resistor structure is specially treated with anti-rain function (SIC harmonic elimination is one of the main indicators of bowel movements after Ling washout not explode), can be used directly outdoors. New LXQ harmonic elimination because of its small size, light weight, high strength, heat dissipation, eliminating the mass RXQ harmonic elimination porcelain shell, but also easy to install, very popular with users of all ages.
