PURPOSE:To efficiently feed a current to a linear motor type railway by dividing LSM ground coil group into 2 sections of the prescribed length, energizing by two power converters the current feeding zones including the section in which a train is located, and switching by the other one between the zones. CONSTITUTION:Two sets of LSM ground coil groups connected independently in series with one another are divided into sections of the prescribed interval like N-1, N, N+1, N+2, the two sections are used as a current feeding zone, the zones are relatively displaced by one section, and disposed. The zones are connected through zone switches 9-12 and then trolley lines 16-18 to 3-phase power converters 13-15 and 3-phase power sources 19. Thus, the zones which include the section in which a train is located, are energized by two power converters, and the zones are switched therebetween by the other one. Accordingly, the power loss is suppressed to reduce the capacity of the power converter unit, and a current feeding system which has high efficiency and high reliability can be provided. |
