摘要
我国客运专线以高架桥为主,接触网遭受雷击的概率较大。为了减轻雷电对接触网造成的危害,在分析国内外接触网防雷情况的基础上,引入了高速铁路电气几何模型(EGM)。通过对模型的分析计算以及与现有防雷措施的比较,同时结合杭深高铁杭州供电段的防雷现状,提出了杭深高铁杭州供电段接触网防雷的改进措施,得出了杭州供电段每百公里每年的雷击跳闸率,为杭州供电段制定相关防雷指标及改进方案提供了理论依据。
Most of passenger dedicated lines in China are primarily viaduct lines,resulting in higher probability of lightning stroke on the catenary.In order to reduce the harm caused by lightning,EGM(electro-geometric model)of high-speed railway is introduced based on the analysis of catenary lightning protection methods both in China and abroad.By analyzing the EGM and compared with the existing lightning protection methods,improved lightning protection measures of Hangzhou power supply section are proposed according to the current situation.The lightning trip-out rate of100km/year on this line is also calculated,providing a theoretical basis for Hangzhou power section to develop the related lightning protection indexes and scheme improvement.
