To provide a conductive device of an insulated wheel for a track maintenance vehicle for improving the safety by reducing the electric power consumption and introducing the fail-safe thought.SOLUTION: The conductive device of an insulated wheel for a track maintenance vehicle includes a primary coil excited by output signals from each of a first AC power source and a second AC power source whose frequencies from a vehicle body side are different from each other, a secondary coil fixed to an outer peripheral surface of an axle so as to face the primary coil, first and second relay coils connected to the secondary coil and making output signals from the first and second AC power sources pass therethrough, and a first relay contact for railroad signals and a second relay contact for crossing control provided on a short circuit for short-circuiting between insulated wheels of axle both end parts. When the first AC power source is energized, both relay signals for railroad signals and relay signals for crossing control are in insulated states. When the fist AC power source is not energized, the relay signals for railroad signals are short-circuited.SELECTED DRAWING: Figure 1
【課題】電気使用量の削減とフェイルセーフ思想を取り入れ安全性を向上させた保線車両用絶縁車輪の導通装置を提供する。【解決手段】車体側からの周波数が異なる第1交流電源及び第2交流電源のそれぞれの出力信号により励磁される1次コイルと、前記1次コイルに対向するように車軸の外周面に固定された2次コイルと、前記2次コイルに接続され、第1、2交流電源からの出力信号を通過させる第1、2のリレーコイルと、輪軸両端部の絶縁車輪間を短絡する短絡回路に鉄道信号用の第1リレー接点及び踏切制御用の第2リレー接点と、を備え、前記第1交流電源が通電しているときには、鉄道信号用のリレー信号と踏切制御用のリレー信号がともに絶縁状態となり、前記第1交流電源が通電していないときには、鉄道信号用のリレー信号が短絡するように構成した。【選択図】図1
