PROBLEM TO BE SOLVED: To provide power source equipment of an alternate current electric motor vehicle which can perform phase switching of a power source without causing instantaneous power stoppage in a middle section.SOLUTION: Until all pantographs of an electric motor vehicle pass through an inlet side air section D1, a tap position of a first tap switching transformer 2 is set as a large output position and a tap position of a second tap switching transformer 3 is set as a small output position. Until a heading pantograph of the electric motor vehicle passes through the outlet side air section D2 after all pantographs of the electric motor vehicle pass through the inlet side air section D1, a tap position of the first tap switching transformer 2 is switched to an output decreasing direction, at the same time, the tap position of the second tap switching transformer 3 is gradually switched to an output increasing direction, the tap position of the first tap switching transformer 2 is set as a small output position and the tap position of the second tap switching transformer 3 is set as a large output position.
【課題】交流電気車の電源設備において、中セクションにおいて瞬時停電を起こすことなく電源の位相切替を行う。【解決手段】電気車の全てのパンタグラフが入口側エアセクションD1を通過するまでは、第1タップ切換変圧器2のタップ位置を大出力位置とし、第2タップ切替変圧器3のタップ位置を小出力位置とする。電気車の全てのパンタグラフが入口側エアセクションD1を通過してから電気車の先頭のパンタグラフが出口側エアセクションD2を通過するまでの間に、第1タップ切替変圧器2のタップ位置を出力減少方向に切り替えながら、第2タップ切替変圧器3のタップ位置を出力増加方向に徐々に切り替えて、第1タップ切替変圧器2のタップ位置を小出力位置とし、第2タップ切替変圧器3のタップ位置を大出力位置とする。【選択図】図2
