Abstract: A rail-bound maglev train comprising a guide rail which predefines a travel path, having at least one supra-conductive element (2) and a levitating vehicle which is arranged on the guide rail and has magnetic means (6), wherein the magnetic means interact magnetically in a contactless fashion with the travel path, and at least one supra-conductive element (2) comprises at least one supra-conductive conductor parallel to the travel path (4), and the at least one supra-conductive conductor has at least two electrical connections, wherein the respective at least two connections bound, on a strip, a strip section, arranged between said connections, as a continuous supra-conductive electrical line.

Abstract: A device for limiting current with variable coil impedance includes a choke coil and a cooling device. An additional coil is made of a high-temperature superconducting material and is disposed in the choke coil such that the current is limited by the device without using an iron core.

Abstract: In a current limiter for limiting currents in case of a fault including an additional device comprising an additional electric valve connected in series and being conductive in the same direction as the associated main valve, two series-connected valve branches arranged in opposition bypass two series connected current limiting inductors and both additional valves are bypassed by a similar passively complex connection for limiting current in the case of a fault, wherein the current limiter is not noticeable during normal operation, but, in the event of a fault, effectively limits the short circuit to a predetermined extent.
