20090166084 | ELECTRICAL BUSHING FOR A SUPERCONDUCTOR ELEMENT - The invention relates to an electrical bushing serving to make a connection at ambient temperature to a superconductor element situated in an enclosure at cryogenic temperature. The electrical bushing passes successively through an enclosure at intermediate temperature between ambient temperature and cryogenic temperature, and an enclosure at ambient temperature, and it comprises a central electrical conductor surrounded by an electrically insulating sheath. According to the invention, an electrically conductive screen connected to ground potential surrounds the insulating sheath over a section that extends from the end of the bushing that is in contact with the enclosure at cryogenic temperature at least as far as the junction between the enclosure at intermediate temperature and the enclosure at ambient temperature. The invention is more particularly applicable to making a connection to a superconductor cable. | 07-02-2009 |
20090239751 | ELECTRICAL CONNECTION STRUCTURE FOR A SUPERCONDUCTIVE ELEMENT - The invention relates to a high voltage electrical connection structure for a superconductive element cooled by a cryogenic fluid in a cryostat and connected to an electrical bushing that passes through at least one enclosure at ambient temperature, said bushing comprising a central conductor having its top end connected by means of a connection arrangement to a connection part extending to outside the enclosure at ambient temperature and passing through a top wall of said enclosure, said central conductor being surrounded over the major fraction of the length by an electrically insulating sheath fastened rigidly to the bottom wall of said enclosure at ambient temperature. According to the invention, said connection arrangement comprises a conductive part mounted on said top end at ambient temperature of the central conductor and a plurality of deformable conductive elements connected to said conductive part and to said connection part, said conductive part having a cylindrical wall surrounding said conductive elements and forming a screen relative to the electric field. | 09-24-2009 |
20100071927 | ELECTRICAL CONNECTION STRUCTURE FOR A SUPERCONDUCTOR ELEMENT - The invention relates to an electrical connection structure for a superconductor element cooled by a cryogenic fluid and connected to an electrical bushing, which bushing passes successively through an enclosure at an intermediate temperature between ambient temperature and the temperature of the cryogenic fluid, and an enclosure at ambient temperature, said bushing projecting outside the ambient temperature enclosure. According to the invention, said intermediate enclosure is filled at least in part with a solid material of low thermal conductivity, such as a polyurethane foam or a cellular glass foam.
