摘要
针对2起500 kV变电站35 kV干式电抗器接地发热故障,介绍了利用红外测温手段发现缺陷和通过辅助试验诊断故障的过程,分析了环流致热和涡流致热原因,提出了相应处理对策和防范措施,从选材、设计、施工和验收等方面给出关于干抗接地体全过程技术监督的建议。
As for the earthing heat fault of 35 kV dry type reactor in two 500 kV substations,the finding of defects by infrared temperature measurement and fault diagnosis by way of auxiliary test are introduced. The reason of heat by both loop current and eddy current is analyzed;the corresponding countermeasures and preventive measures are proposed. The suggestion on technical supervision of the earthing of dry type reactor is given from such aspects as material selection,construction and acceptance etc.
