摘要
针对复合硅橡胶套管时常发生雨闪事故,严重影响电网安全稳定运行的问题,对雨闪事故原因进行分析研究,提出了在复合硅橡胶套管上增加辅助伞裙的设计方案。应用结果表明:采用增加辅助伞裙的方法能有效的避免雨闪事故的发生,保证电网安全可靠运行,同时具有显著的经济效益。
The rain flashover accidents which frequently occur at composite silicone rubber casing,seriously affect the safe and stable operation of power grid. Aiming at the problem,analyzes andresearches the reasons of the accident,puts forward the design scheme of adding auxiliary umbrellaskirt on the composite silicone rubber casing. The application result shows that the method ofadding auxiliary umbrella group can effectively avoid the rain flashover accident and guarantee thesafe and reliable operation of the power grid,has prominent economic benefits.
