Abstract:
A superconducting device, comprising:at least one inductive current limiter unit, comprising: a conductor track which carries a switching current in a limiting situation, track and is formed of high-Tc superconductor material, and a core limb which is surrounded by the annular body and is formed of soft-magnetic material; and a transformer comprising: a primary coil winding of a conductor; a secondary coil winding of a conductor, the conductor track being formed from the conductor of at least one of the primary and secondary coil windings; and a magnetic flux body composed of soft-magnetic material and having at least first, second and third yoke limbs, the first and second yoke limbs being associated respectively with the primary and secondary coil windings, the third yoke limb being provided between the primary coil winding and the secondary coil winding of the transformer, the third yoke limb serving as the yoke limb for the current limiter unit.
