加装避雷线提升高铁接触网防雷水平方案分析

Case Study on Adding Lightning Conductor to Improving Lightning Protection Levels for High-speed Railway OCS(Overhead Contact System)

基于我国高速铁路现有接触网的主要结构和参数,计算分析高铁接触网无架空地线的耐雷水平,提出在支柱顶端和侧面加装避雷线方案,并分别与未加装前比较,得到不同方案对高铁接触线防雷的改善效果,提出实际应用建议。

Based on the primary structure and parameters for the existing high-speed railway OCS,the article cal-culates and analyses the lightning protection level of high-speed railway OCS without overhead ground wire. It putsforward a proposal to add the lightning conductor on the top and at the side of the pillar,makes a comparison to thesituations before adding the lightning conductor separately to obtain the improved effects of different proposals inview of lightning protection of high-speed railway OCS,thus making practical application suggestions.
