To provide an insulation/short-cut switching device of insulation wheels which can reliably obtain power supply voltage in a stable manner and which can reliably combine in an electromagnetic induction manner even if distance between a transmission coil and a power receiving coil varies.SOLUTION: An insulation/short-cut switching device of insulation wheels is configured such that distance capable of electromagnetically inducing is secured by one transmission coil approaching a power receiving coil even when the other transmission coil separates from the power receiving coil because oppositely disposing two sheets of transmission coil on both outsides of the power receiving coil at an interval and then composite voltage of the two sheets of transmission coil is received by the power receiving coil, so that the composite voltage of the two sheets of transmission coil is reliably received by the power receiving coil. A transmission side circuit is configured so as to generate two or more modulation carrier waves (control signal) which apply modulation by two or more modulation waves with distinct frequency to the modulation wave transferring electric power and then send the same to the transmission coil. A power receiving side circuit operates a switch by power system voltage on the basis of the control signal and then makes it possible to switch an inner ring and an outer ring of insulation wheels to dead short-cut, partial short-cut and perfect insulation.SELECTED DRAWING: Figure 1
【課題】電源電圧が安定して確実に得られ、送電コイルと受電コイルの間隔が変動しても確実に電磁誘導結合できる絶縁車輪の絶縁・短絡切替え装置を提供する。【解決手段】二枚の送電コイルを受電コイルの両外側に間隔をあけて対向配置して、二枚の送電コイルの合成電圧が受電コイルに受電されるようにしたことにより、一方の送電コイルが受電コイルから離れても他方の送電コイルが受電コイルに接近して、電磁誘導可能な間隔が確保され、二枚の送電コイルの合成電圧が受電コイルに確実に受電される。送電側回路は電力を伝送する搬送波に周波数の異なる二以上の変調波で変調をかけた二以上の変調搬送波(制御信号)を生成して送電コイルに送る構成とし、受電側回路は制御信号に基づいて電力系電圧によりスイッチを操作して、絶縁車輪の内輪と外輪を完全短絡、部分短絡、完全絶縁に切替え可能とした。【選択図】図1
