PROBLEM TO BE SOLVED: To provide a vehicle electric power conversion system in which stable cooling performance is obtained and the attachment/detachment operability of an electric power conversion unit is improved, and to provide a railway vehicle.SOLUTION: An vehicle electric power conversion system according to one embodiment includes: a box body having a bottom wall part; an electric power conversion unit stored in the box body; a heat radiation unit fixed to a lower surface of the bottom wall part and radiating heat generated by the electric power conversion unit at the outer side of the box; supporting rails which are placed on an upper surface of the bottom wall part and slidably support the electric power conversion unit; guide members, each of which is erected on the upper surface of the bottom wall part and guides the supporting rail so that the supporting rail may move in a vertical direction; and fixing members, each of which may fix the electric power conversion unit through the supporting rail with the electric power conversion unit pressed against the upper surface of the bottom wall part and also may fix the supporting rail separated from the bottom wall part along the guide member at a given height.

    【課題】安定した冷却性能を得ることができると共に、電力変換ユニットの着脱操作性が向上した車両用電力変換装置及び鉄道車両を提供することである。【解決手段】実施形態の車両用電力変換装置は、底壁部を有する箱体と、前記箱体の内部に収容された電力変換ユニットと、前記底壁部の下面に固定され、前記電力変換ユニットで発生する熱を前記箱体の外側で放熱する放熱ユニットと、前記底壁部の上面に載置されると共に、前記電力変換ユニットをスライド移動可能に支持する支持レールと、前記底壁部の上面に立設され、前記支持レールを上下方向に移動可能にガイドするガイド部材と、前記支持レールを介して前記電力変換ユニットを前記底壁部の上面に押し付けた状態で固定可能であり、さらに前記ガイド部材に沿って前記底壁部から離間した前記支持レールを任意の高さで固定可能な固定部材と、を持つ。【選択図】図3
