摘要
简要介绍了河北南部电网近期发生的3起隔离开关支柱绝缘子断裂事故,结合电网运行中实际操作案例提出了优化倒闸操作方案以降低隔离开关支柱绝缘子断裂危害的几种方法,并给出了应对此类问题的建议。
Recent three rupture faults of isolating switch post insulator occurred in Hebei South Electric Power Network are introduced firstly, combined with the practice cases during operation, some methods of optimizing the operating scheme to reduce the insulator rupture risk are raised, in the end some proposals to deal with such problems are presented.
