摘要:
A power supply line for connecting a superconducting consumer system to a current delivery point, which is at a higher temperature than the consumer system, includes a carrier and a plurality of band-shaped, mechanically and electrically parallel high-temperature superconductors (HTSL). To achieve a high critical current density with simultaneously low heat-conducting capacity of the power supply line, the carrier includes at least one elongated plate that includes a sparingly (low) heat-conducting material, with a ratio of width to thickness of at least 3:1 and band-shaped HTSL that are arranged parallel adjacent to one another on the carrier. Each band-shaped HTSL also has a normally conducting current path.

A method and device for quality control of superconducting bands includes: cooling a section of the superconducting band to a temperature at which said band section becomes superconducting, generating an electrical transport current in the superconducting band section in the longitudinal direction of the band by contacting with a contact assembly, contacting the cooled band section with electrical contacts of the contact assembly, which are spaced apart in the longitudinal direction of the band, in order to form a measurement section over a partial length of the band section, continuously moving at least one part of the band through the contact section and/or measurement section to generate the transport current, detecting a physical measured variable using measurement contacts, wherein the physical measured variable is a measure of the superconducting electrical transport properties of the band section or a part of the band.

A linear machine comprises a primary part and a secondary part. The primary part forms a receptacle around an axis and has a plurality of annular primary coils, which are arranged concentrically with respect to the axis, can have alternating current applied to them, and are separated by intermediate elements, in order to produce a magnetic field in the receptacle. The secondary part, which can be moved relative to the primary part by the magnetic field in the receptacle along the axis, is provided with secondary coils having superconductor windings. In order to produce a linear motor which allows high force densities, the intermediate elements are produced from non-magnetizable material and the primary coils and the secondary coils are arranged with an air-gap winding, wherein the secondary coils are manufactured from a high-temperature superconductor and direct current can be applied or is applied to them. Force densities of more than 18 N/cm2 can be achieved in the receptacle by the linear motors.
