Patent ID: 7981841

Claim:
A superconducting current-limiter resistive device, comprising: a conductor track formed as a strip, the conductor track comprising: a substrate strip formed of a normally conductive substrate metal; a superconducting layer formed on the substrate strip, the superconducting layer being formed of an oxidic high-T C superconductor material of AB 2 Cu 3 O x , with A being at least one element selected from the group consisting of rare earth metals and yttrium, and B being at least one alkiline earth metal; a buffer layer between the substrate strip and the superconducting layer, the buffer layer being formed of an oxidic buffer material; and a covering layer formed on the superconducting layer, the covering layer being formed of a normally conductive covering metal; and a spacer, the conductor track being in the form of a bifilar coil, the spacer being arranged between adjacent coil turns of the bifilar coil, the spacer creating a space for a coolant to flow, the spacer maintaining a constant distance between adjacent coil turns, the spacer being aligned along a flow direction of the coolant, wherein at least one electrical contact point is provided between the covering layer and the substrate strip, the bifilar coil formed from the conductor track and the spacer are mechanically intrinsically stable, and the bifilar coil and the spacer are adhesively bonded together only in mutually touching areas, with a synthetic resin, the conductor track and the spacer being bonded in sections so as to leave open coolant paths.
