        摘要:
        研究地鐵高架段接觸軌線路雷擊閃絡特性,對制定接觸軌防雷標准有著十分重要的意義。文中基于滾球法分析了接觸軌高架橋段線路易發生的雷擊類型,在此基礎上,搭建了地鐵高架段接觸軌模型,研究不同雷擊類型條件下對應的雷擊閃絡特性,分析了橋墩接地電阻改變對各導體之間電壓的影響。研究發現:地鐵高架段接觸軌供電系統主要受雷擊避雷帶跟雷擊列車這兩種雷擊類型的影響。當雷擊避雷帶時,接觸軌感應過電壓造成絕緣支架閃絡所需的雷電流水平低于地電位反擊所需的雷電流水平,因此感應過電壓是造成絕緣支架閃絡的主要原因。而雷擊列車時,雷電流幅值達到118 kA才會通過感應的形式造成絕緣支架閃絡,但此時累積概率較小,因此工程上認爲引發絕緣支架閃絡的可能性不高。
        Abstract:
        It is very significant to setting up lightning protection standard for contact rail, studying on lightning flashover characteristics of contact rail line along viaduct section. The paper is based on the roiling ball method, the lightning strike type about metro contact rail are divided. On this basis, building the contact rail model of elevated section under different lightning stroke types, the lightning flashover characteristics under different lightning strike types are studied, and the influences of pier grounding resistance change on conductor voltage difference are analyzed. The research founds that two types between lightning strikes lightning strip and lightning strike train are prone to occur. When lightning strikes the lightning strip, lightning current level required for insulation bracket flashover, which caused by induced overvoltage of the contact rail is lower than that of ground potential counterattack, so the main reason for the insulation bracket flashover is the induced overvoltage. When lightning strikes the train, the lightning current amplitude reaches 118 kA, which will cause the insulation bracket flashover through the form of inducted overvoltage, but the cumulative probability is small, so the probability of lightning strike triggered insulated guardrail flashover is not high.
