To reduce a power switching time of a power supply switch for an electric machine type railroad.SOLUTION: In a double-throw/double-edged electromagnetic contactor connected to a regular power source, a standby power source, and electrical equipment, an electromagnetic contactor 60 is adopted. The electromagnetic contactor 60 is a two axial type that supports both movable element of a movable element 62 having a movable contact 32 on the regular power source side and a movable element 64 having a movable contact point 42 on the standby power source side with individual support axes 63, 65 so as to be swingable, and interlocks through a cam mechanism 61, and a switching operation is fast. A smoothing circuit 51 that smooths pulsating flow in a power storage is added into a driving circuit 13 on the standby power source side to further increase the switching speed to the standby power source, while suppressing increase of an additional member by only driving a driving circuit 12 on the regular power source side in the pulsating flow.SELECTED DRAWING: Figure 1

    【課題】電気機械式の鉄道用電源切替器の電源切替時間を短縮する。【解決手段】常用電源と予備電源と電気機器とに接続される双投双刃形の電磁接触器に電磁接触器60を採用する。電磁接触器60は、常用電源側の可動接点32を具備した可動子62と予備電源側の可動接点42を具備した可動子64との両可動子を個別の支軸63,65にて揺動可能に支持するとともにカム機構61を介して連動させる二軸式のものであり、切替動作が速い。また、脈流を蓄電にて平滑化する平滑回路51を予備電源側の駆動回路13に追加して予備電源への切替速度を更に高める一方、常用電源側の駆動回路12は脈流で駆動するにとどめて部材追加の増加を抑制する。【選択図】 図1
