摘要
本文结合雷害比较的几条电气化铁路接触网设计 ,以及雷害发生的情况 ,对雷电机理、耐雷水平等进行了全面分析 ,找出了其雷害防护的薄弱环节。并根据我国雷电活动频度 ,借鉴电力部门和日本国铁防雷理论 ,以年平均雷暴日 6 0天为分界 ,提出不同防雷保护措施。
Combined with the design of catenary in several electrified railways with lightning defects more frequently and the situations of occurred lightning defects, the overall analyses on lightning mechanism, anti lightning level, etc, are put forward and the weak links for lightning protection have been obtained.Based on the frequency of lightning activity in China and taking the lightning protection theories of Power Supply Department in China and National Railways in Japan as reference, the different lightning protection measures are proposed on the boundary of average 60 lightning days per year.
