一起110kV干式穿墙套管介损超标的原因分析和处理

摘要

根据一只110kV干式穿墙套管介损试验超标情况，通过解体检查，找出导致数据异常的故障部位，结合套管结构进行原因分析，提出了此类套管的运行防范措施。%According to the excessive dielectric loss test of a 110 kV dry through-wall casing, we identified the fault location which leaded to the data anomalies by the way of checking the disintegration. We made an analysis of the casing structure, and proposed the running preventive measures of such casings.
