概述General introduction
RXQ3型消谐器是串接在6～35kV电压互感器一次绕组中性点与地之间的一种非线性电阻消谐阻尼器件，用于消除电网运行、切换操作及接地故障引起的电压互感器铁磁谐振，有效限制接地电流，使电压互感器免于损坏。
RXQ3 resonance eliminator is a nonlinear resonance elimination damper resistance cascaded to between 6 ~ 35kV voltage transformer primary winding neutral point and the ground, used for the elimination of voltage transformer is ferromagnetic resonance caused by grid operation, switching operation and grounding fault to effectively limit ground current and protect voltage transformers from damage.
RXQ3型消谐器的电阻元件选用电气性能优异、超细颗粒的稀有金属为基材的配方体系，经大吨位的液压机压制成高密度的饼型坯体及千度高温烧结而成，裸露的的电阻元件表面结构经特殊处理，可户外裸露使用。
The resistive elements of RXQ3 resonance eliminator are made by pressing the formula system with excellent electrical performance, ultra-fine particles and metals as the base material into high-density green body the large-tonnage hydraulic machine body by large-tonnage hydraulic machine and then go through thousand degrees high temperature sintering. Through special processing, the bare resistive element special surface structure can be exposed for outdoor use.
