Zusammenfassung:To apply a contactless power supply technology to a train.SOLUTION: In a high-frequency power source distributed installation type transmission line 1, a covered high-frequency oscillator distributed arrangement type transmission line 10b includes an outer conductor 12, a power transmission line W, and a high-frequency oscillator I, and a positive potential output from the high-frequency oscillator I is connected to a power transmission electrode 101 which is arranged so as to be insulated from the outer conductor 12, and the ground output from the high-frequency oscillator I is connected to a metal cover 12. A switching unit includes a switch 31 and a determination circuit N. A train T includes a power reception electrode 201 that faces the power transmission electrode 101 in a non-contact manner, and a power reception electrode 202 that faces the metal cover 12 in a non-contact manner, and moves using power received from the power transmission line via the junction capacitance formed by the power transmission electrode 101 and the power reception electrode 201 and the junction capacitance formed by the metal cover 12 and the power reception electrode 202.SELECTED DRAWING: Figure 4B 【課題】電車に対して非接触給電技術を適用すること。【解決手段】高周波電源分散設置型送電線路1において、カバー付き高周波発振器分散配置型送電線路10bは、外部導体12と、送電線Wと、高周波発振器Iとを備え、高周波発振器Iからのプラス電位の出力が、外部導体12と絶縁されて配設された送電電極101に接続され、高周波発振器Iからのグランド出力が金属カバー12に接続される。スイッチングユニットは、スイッチ31と判断回路Nとを備える。電車Tは、送電電極101と非接触で対向する受電電極201と、金属カバー12と非接触で対向する受電電極202とを備え、送電電極101と受電電極201とにより形成される接合容量と、金属カバー12と受電電極202とにより形成される接合容量とを介して前記電力伝送線路から受電した電力を用いて移動する。これにより上記課題を解決する。【選択図】図4B
