摘要
江西超高压主网500 kV变电站内TBB14-35-54000/500M-2AQW型无功补偿电容器组由于连接组件存在结构性缺陷,造成运行过程中发热故障频繁,严重威胁电力系统稳定运行。文中对电容器组过热情况进行归纳总结;就缺陷原因本质有针对性地改进设计电容器组连接部位(新型H线夹);同时对线夹材质采用黄铜锡镀工艺,增强设备耐腐程度。通过多个变电站现场安装使用,发现红外测温效果和检修简便性均优于哈弗线夹,为无功补偿电容器组的运行维护提供了参考。
The heat fault for type TBB14-35-54000/500M-2AQW reactive capacitor at 500 kV substation in Jiangxi EHV grid is occurred frequently due to structural defect of connections and stable operation of the power system is affected seriously. In this paper,the overheating of capacitor bank is summa- rized and the design improvement of the capacitor connection （new type H clip） is made and the brass plated with in process for the clip is used to increase corrosion resistance of the equipment. It is found throughout the installation and application at many substations that the infrared temperature measurement result and maintenance convenience are superior to Harvard clip ,which provides reference for the operation and maintenance of reactive compensation capacitor.
