To provide an insulation/short-circuit replacement device and a track maintenance vehicle with the device by which an induced voltage between a primary coil and a secondary coil is surely acquired even when a distance from a truck to an axle varies, a switch can be made to operate with a small current and a prompt replacement can be done without a long-term deterioration.SOLUTION: In the device, a primary coil of a transmission module of a transmission unit and a secondary coil of a power incoming module are installed to face each other with a gap enabling both coils to have an electromagnetic resonance coupling, a switch is provided in a control circuit in an output side of the secondary coil, and a LPF is provided in the output side of the switch. The switch opens or closes by the voltage induced by an electromagnetic resonance coupling of the coils, makes an inner wheel and an outer wheel mutually short-circuit perfectly, insulate perfectly or partially short-circuit. The switch is a semiconductor switch.SELECTED DRAWING: Figure 1
【課題】台車と車軸の間隔が変動しても、一次コイルと二次コイル間で確実に誘起電圧を得ることができ、スイッチを小電流で操作でき、経年劣化せずに迅速な切替え操作可能とする絶縁・短絡切替え装置と、その装置を備えた保線車両を提供する。【解決手段】装置では、送電ユニットの送電モジュールの一次コイルと受電モジュールの二次コイルが電磁界共振結合可能なギャップをあけて対向配置されており、二次コイルの出力側の制御回路にスイッチを有し、スイッチの出力側にLPFを有する。スイッチは、前記両コイルの電磁界共振結合により誘起される電圧で開閉して、内輪と外輪が完全短絡、完全絶縁又は部分短絡する。スイッチは、半導体スイッチとする。【選択図】図1
