<p>A fault current limiter, with a superconducting device (1; 21; 31; 41; 51; 61; 71; 72) comprising a sequence of superconducting elements (2a-2f), each with
- a substrate (3a-3d),
- a superconducting film (5a-5d), and
- an intermediate layer (4a-4c) provided between the substrate and the superconducting film,
wherein the superconducting films (5a-5d) of adjacent superconducting elements (2a-2f) of the sequence are electrically connected, in particular in series, is characterized in that the substrates (3a-3d) of the superconducting elements (2a-2d) are electrically conducting substrates (3a-3d),
wherein the electrically conducting substrate (3a-3d) of each superconducting element (2a-2f) of the sequence is electrically insulated from each electrically conducting substrate (3a-3d) of those adjacent superconducting elements (2a-2f) within the sequence whose superconducting films (5a-5d) are electrically connected in series with the superconducting film (5a-5d) of said superconducting element (2a-2f),
and that the intermediate layers (4a-4c) of the superconducting elements (2a-2f) are electrically insulating layers (4a-4c). The inventive fault current limiter is cost efficient in production, and is capable of a short recovery time after a quench event.</p> |
