PROBLEM TO BE SOLVED: To provide a pantograph abnormality detection method capable of detecting wear with steps or the like which is in a portion where there is large trolley wire deviation.SOLUTION: A load applied to a curve trigger tool 45 for supporting a trolley wire T in a rail straight angle direction, is measured. When an absolute value of the load exceeds a predetermined threshold, or increase or decrease of the load exceeds a predetermined threshold, it is determined that there is abnormality on a pantograph.
【課題】 大きな電車線偏位の箇所にある段付摩耗などについても検知できるパンタグラフ異常検知方法を提供する。【解決手段】 トロリ線Tをレール直角方向に支持する曲線引金具45にかかる荷重を測定する。該荷重の絶対値が所定の閾値を超えるか、又は、該荷重の増加若しくは減少が所定の閾値を超えた場合に、パンタグラフに異常可能性有りと判定する。【選択図】図1
