摘要： An electrically connecting device (1) includes a linking part defining an internal channel (12) that opens onto the exterior of the linking part. The internal channel (12) is able to receive two end segments of two superconducting wires (2, 3) that lie parallel in the internal channel (12) over a segment of common length; and an aperture (13) in the external jacket of the linking part. The aperture (13) is in communication with the internal channel (12) in order to allow a brazing material in liquid form to be inserted into the internal channel (12) around the two end segments of the two superconducting wires (2, 3).

摘要： A superconducting cable (1) includes a superconducting cable core (2) and a corrugated pipe (21) storing the superconducting cable core (2). The superconducting cable core (2) has a corrugated pipe (11), a superconductor (12) provided on the outer peripheral side of the corrugated pipe (11), and a heat insulating pipe (23) stored in the corrugated pipe (11) and having a smooth inner peripheral surface. A coolant flows through a flow passage (FP1) formed in the heat insulating pipe (23) and then flows through a flow passage (FP2) formed between an outer peripheral surface of the corrugated pipe (11) and an inner peripheral surface of the corrugated pipe (21).

摘要： The present disclosure relates to DC transmission. Some embodiments may include a device for DC transmission comprising: a superconducting transmission line including a superconducting conductor element; and a cooling device for cooling an inner region of the transmission line with a fluid coolant to a temperature below a critical temperature of the superconducting conductor element. The superconducting transmission line may comprise a vacuum-insulated sleeve thermally isolating the inner region of the transmission line from a warmer outer surrounding area. The cooling device may comprise a feed device feeding coolant at an end region of the transmission line into the inner region of the transmission line. The transmission line may be free of internally arranged feed devices for feeding coolant at locations away from the end region.

摘要： Provided are a superconductive wire and a superconductive coil that have sufficient superconductivity and may be manufactured through a simple manufacturing process. The superconductive wire includes a tape-shaped substrate having a main surface and a superconductive layer provided on the main surface. A critical current flowing through an end portion in the width direction perpendicular to the extending direction of the substrate is larger than a critical current flowing through a central portion in the width direction.

摘要： Specified is an arrangement for supplying power to a motor vehicle which is equipped with an electric motor and in which there is arranged at least one rechargeable electric battery to which the electric motor is connected. The arrangement includes a stationary charging station which is equipped with an electric power source and to which an electric line having at least two mutually insulated electrical conductors is connected, a part of an electrical coupling for connecting to a complementary coupling part present on or in the motor vehicle being attached to the free ends of said electrical conductors, said coupling part being connected to the battery in an electrically conductive manner. The electric line is surrounded along its entire axial length by a thermally insulated and flexible tube made of metal which is closed all around and which, in addition to the line, encloses a cavity along its entire axial length. A flowable medium refrigerated to a temperature of at least −160° C. is contained in the space enclosed by the tube, and a thermally insulated storage tank containing a store of the refrigerated medium is arranged in the charging station, the tube being connected to said storage tank.
