電気鉄道の安全安定輸送を確保するため，雷害防止が求められている。本論文では，電気鉄道設備の雷サージ特性実測を行い，接地インピーダンス特性を雷サージの視点から検討した。さらに，電力系統解析技術を応用して鉄道特有機器の回路解析モデルを開発し，その精度を実測で確認し，鉄道設備雷電流侵入時の応答を実測および計算結果より明らかにした。これらの成果は，電気鉄道の設計・保守・解析に十分に生かすことが可能である。 / Lightning protection is required to ensure safe and stable electric railway transportation. In this thesis, the lightning surge characteristics of the facilities in electric railway systems were measured. The characteristic of earthing impedance was also investigated from the viewpoint of lightning surge. In addition, some numerical models of railway specific apparatuses for circuit analysis method were developed by applying simulation technology for power system and confirmed their accuracies by actual measurements. The responses to lightning currents invaded into the facilities were clarified by the measured and calculated results. These results can be fully utilized in the design, maintenance and analysis of electric railway systems. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University
