PROBLEM TO BE SOLVED: To provide an abnormality monitoring device of a trolley wire or the like which can detect a variety of kinds of abnormalities related to the trolley wire or a pantograph by an arc which is generated at a contact point between the trolley wire and the pantograph of an electric railway, an abnormality detection method and an abnormality analysis program.SOLUTION: An abnormality monitoring device of a trolley wire comprises: a plurality of wire-separation measurement instruments 11 to 13 which are arranged at intervals in a vehicle traveling direction of the trolley wire 4, and detect arcs which are generated at contact points between the trolley wire 4 and a pantograph; and a calculation device 14 which determines an abnormality of the trolley wire between detection zones by comparing a generation pattern of the arcs which are detected by the wire-separation measurement instruments 11 to 13 with a reference generation pattern of the arc.SELECTED DRAWING: Figure 1
【課題】この発明は、電気鉄道におけるトロリ線とパンタグラフとの接触点で発生するアークにより、トロリ線又はパンタグラフに関する種々の異常を検出できる、トロリ線等の異常監視装置、異常検出方法及び異常解析プログラムを提供する。【解決手段】トロリ線4の車両走行方向に間隔をおいて配置されて、該トロリ線4とパンタグラフとの接触点で発生するアークを検出する複数の離線測定器11〜13と、これら離線測定器11〜13で検出されたアークの発生パターンを、アークの基準発生パターンと比較することにより、検出区間のトロリ線異常を判定する演算装置14と、を具備する。【選択図】図1
