Resistive type super conductive current-limiting device comprising a strip-shaped high-Tc-super conductive path

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-TC superconductor material of AB2Cu3Ox, 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.
