PROBLEM TO BE SOLVED: To provide a train pantograph automatic descent system capable of quickly detecting breakage of a pantograph, protecting a circuit on a vehicle side, and suppressing breakage of a wiring or other pantograph due to the broken pantograph.SOLUTION: A train pantograph automatic descent system of the invention makes all pantographs 3A, 3B descend when the pantograph 3A, 3B is broken. When lifting control means V (electromagnetic valve) lifts up the pantographs 3A, 3B, and one of pressure detection means PS becomes in an off state, the descend system operates the lifting control means V so as to make plural current block devices 6A, 6B to perform an opening operation and make all pantographs 3A, 3B descend.SELECTED DRAWING: Figure 6

    【課題】パンタグラフの故障を速やかに検出でき、車両側の回路を保護しつつ、故障したパンタグラフによる架線や他のパンタグラフの損傷を抑制できる電車用パンタグラフ自動降下システムを提供する。【解決手段】パンタグラフ3A、3Bに故障が生じた場合に、全てのパンタグラフ3A、3Bを降下させる電車用パンタグラフ自動降下システムにおいて、昇降制御手段V(電磁弁)がパンタグラフ3A、3Bを上昇させている場合であって、圧力検知手段PSの一つがオフ状態になった場合に、複数の電流遮断器6A、6Bに開放動作を行わせ、全てのパンタグラフ3A、3Bを降下させるように昇降制御手段Vを動作させる。【選択図】図6
