摘要： PROBLEM TO BE SOLVED: To enhance propulsion efficiency by reducing eddy current loss of a propulsion coil and to reduce power consumption.
SOLUTION: The ground coil device is installed on a track for a magnetic levitating type railway and is constituted by winding a cable. In the used cable 31, a twisted wire conductor 33 is constituted by twisting a plurality of element wires 32 in which an insulation material 32b is covered on a naked element wire 32a. An inner semiconductive layer 34, an insulation layer 35 and an outer semiconductive layer 36 are formed on a periphery of the twisted wire conductor 33 in the order from the inner side. A sheath buried with a wire shield 37 is further formed on the periphery. The eddy current is induced on the twisted wire conductor 33 by variation magnetic field by an ultra-conductive magnet at a vehicle side, however, since the element wire 32 of the twisted wire conductor 33 is the insulation element wire, the eddy current induced on the twisted wire conductor 33 is suppressed and the eddy current loss is reduced.

摘要翻译：要解决的问题：通过减少推进线圈的涡流损耗并降低功耗来提高推进效率。解决方案：接地线圈装置安装在用于磁悬浮式铁路的轨道上，并且通过缠绕电缆构成。在使用过的电缆31中，绞合线导体33通过将裸线元件线32a上的绝缘材料32b覆盖的多个元件线32进行扭转而构成。内部半导体层34，绝缘层35和外部半导体层36以内侧的顺序形成在绞线导体33的周围。在外围还形成有用屏蔽罩37埋设的护套。涡电流是通过在车辆侧的超导磁体的变化磁场而在双绞线导体33上感应出来的，然而，由于绞合导体33的元件线32是绝缘元件线，因此导致的涡电流扭绞线导体33被抑制，并且涡流损耗降低。版权所有（C）2006，JPO＆NCIPI
