To provide an overhead train line and a method for determining abnormality in the overhead train line capable of effectively preventing arc generation to prevent breaking of a trolley wire under a condition where a distance between the trolley wire and a pantograph is extremely increased such as where the pantograph is lowered by weight of accumulated snow.SOLUTION: An overhead train line comprises: a trolley wire 7 on which a sliding plate of a pantograph slides; a protective wire 6 located above the trolley wire 7 and supported by a suspension wire 3 intermittently via hangers 4 at multiple longitudinally arranged positions, further above which the suspension wire is located; ears 5 disposed at multiple longitudinally arranged positions on the trolley wire 7 and mutually connecting the trolley wire 7 and the protection wire 6; and distortion detecting means disposed on the protection wire 6 and detecting distortion of the protection wire 6.SELECTED DRAWING: Figure 1

    【課題】この発明は、積雪によるパンタグラフ降下のようにトロリ線とパンタグラフとの間隙が極端に大きくなる状況下において、アーク発生を有効に防ぎトロリ線断線を未然に防止することができる架空電車線及び架空電車線における異常判定方法を提供する。【解決手段】パンタグラフのすり板が摺動するトロリ線7と、トロリ線7の上方に位置しかつ長さ方向に沿う複数箇所にてハンガ4を介してさらに上方に位置する吊架線3に間欠的に支持される保護線6と、トロリ線7の長さ方向に沿う複数箇所に設けられかつ該トロリ線7と保護線6とを互いに連結するイヤー5と、保護線6に設けられて該保護線6の歪みを検出する歪み検出手段と、を具備する。【選択図】図1
