The invention relates to a rail vehicle pantograph enabling circuit which comprises two units symmetrically arranged on a train, each unit comprises a first branch and a second branch. Each first branch comprises a train activation relay normally-closed contact, a train activation relay normally-open contact and a pantograph enabling relay which are connected between train power sources in series,a first terminal of a knife switch of a high-voltage box is connected between the train activation relay normally-closed contact and the train activation relay normally-open contact, and a second terminal of the knife switch of the high-voltage box is connected with a second terminal of a knife switch of a high-voltage box of a first train line opposite side uni. Each second branch comprises a cab activation relay normally open contact, an enabling bypass switch and a pantograph enabling relay which are connected in series between train power supplies. The upstream ends of the pantograph enabling relays of the two units are connected through a second train line. The pantograph enabling circuit of the railway vehicle can guarantee effective output of pantograph enabling signals.

    本发明涉及轨道车辆受电弓使能电路,包含对称设置于列车的两个单元,每个单元包含有第一支路和第二支路,第一支路包含串联于列车电源间的列车激活继电器常闭触点、列车激活继电器常开触点和受电弓使能继电器,高压箱的刀开关的第一端子接在列车激活继电器常闭触点和列车激活继电器常开触点之间,高压箱的刀开关的第二端子通过第一列车线接对侧单元的高压箱的刀开关的第二端子;第二支路包含串联于列车电源间的司机室激活继电器常开触点、使能旁路开关和受电弓使能继电器,两个单元的受电弓使能继电器的上游端通过第二列车线连接。本发明轨道车辆受电弓是能电路能够保证受电弓使能信号的有效输出。
