PROBLEM TO BE SOLVED: To provide an overhead wire structure of an electric train line for supplying direct-current power which can cope with a heavy load wire section, can suppress the overhead height of suspending a trolley wire, and improves a current collection performance.SOLUTION: There is provided an overhead wire structure of an electric train line which has a feeder wire (11) for transmitting direct current power from a sub station and a trolley wire (13) for transmitting the direct current power to a current collecting device of a railway vehicle by contact; and further has a feeder suspension wire (12) that has a smaller current capacity than that of the feeder wire (11) and is electrically connected to the feeder wire (11), where the feeder wire (11) and the feeder suspension wire (12) are suspended through a support pulley (15), and the trolley wire (13) is electrically connected to the feeder suspension wire (12) and is suspended by the feeder suspension wire (12).SELECTED DRAWING: Figure 1
【課題】直流電力を供給する電車線路の架線構造において、重負荷線区にも対応でき、トロリー線を吊架する構成の架高を抑えることができ、さらに、集電性能を向上する。【解決手段】変電所から直流電力を伝送するき電線(11)と、鉄道車両の集電装置へ接触により直流電力を送るトロリー線(13)とを備えた電車線路の架線構造である。そして、き電線(11)よりも電流容量が小さく、且つ、き電線(11)と電気的に接続されるき電吊架線(12)をさらに備え、き電線(11)およびき電吊架線(12)は、支持滑車(15)を介して架設され、トロリー線(13)は、き電吊架線(12)と電気的に接続され、且つ、き電吊架線(12)に吊架されている。【選択図】図1
