摘要
文章收集了四川省电力公司范围内挂网运行复合绝缘子重要掉串事件,对芯棒脆断机理进行了深入分析,提出了早期复合绝缘子由于结构缺陷导致芯棒渗水酸化脆断的结论。并对目前四川复合绝缘子运行中存在的问题进行了分析,对今后如何做好复合绝缘子运行工作提出了建议和意见。
The important affairs of composite insulator string dropping in Sichuan Electric Power Corporation （SPEC） are described, the mechanism of brittle fracture of insulator rod is analyzed, and the conclusion is proposed that the acidification and brittle fracture of the early composite insulator rod are caused by water penetration due to structural defects. Furthermore, the problems existing in the composite insulators that are in operation presently in SPEC are analyzed, and the advices and suggestions are proposed for the composite insulator in the future work.
