たりするという問題があった。However, in this type of overhead wire support structure, a feeder for supplying electric power to the trolley wire is erected and supported on the upper portion of the yagura via a support frame or the like. Is extended above the stay. Since the stays are arranged in an oblique shape, even if birds such as crows stop on the stays, they are not stable and often flap their wings. Therefore, when a bird flaps, its wings come into contact with a feeder and a ground fault occurs, which causes a problem that power is not normally supplied to the trolley wire or a signal system is adversely affected.

架線支持構造を提供することにある。The present invention has been made by paying attention to the problems existing in such a conventional technique. The purpose of the present invention is to detect a bird or the like stopped on a stay for an overhead wire supporting beam. An object is to provide an overhead wire support structure capable of reliably preventing a ground fault accident.

を確実に防止することができる。According to the overhead wire supporting structure constructed as described above, the stays are provided with insulators at both ends thereof, and the stay is insulated from the supporting beam and the tower. Therefore, even if a bird such as a crow stops on the stay and flaps and touches the feeder, a ground fault does not occur via the stay. Therefore, it is possible to reliably prevent the possibility that the power supply to the trolley wire is not normally performed or the signal system is adversely affected due to the ground fault.
