概述General introduction
RXQ3型消諧器是串接在6～35kV電壓互感器一次繞組中性點與地之間的一種非線性電阻消諧阻尼器件，用于消除電網(wǎng)運行、切換操作及接地故障引起的電壓互感器鐵磁諧振，有效限制接地電流，使電壓互感器免于損壞。
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型消諧器的電阻元件選用電氣性能優(yōu)異、超細顆粒的稀有金屬為基材的配方體系，經(jīng)大噸位的液壓機壓制成高密度的餅型坯體及千度高溫?zé)Y(jié)而成，裸露的的電阻元件表面結(jié)構(gòu)經(jīng)特殊處理，可戶外裸露使用。
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.
