3-phase superconducting cable system with redundancy

Abstract

A 3-phase superconducting cable system (100) has four 1-phase superconducting cables (A, B, C, D). Interrupting switches (S1, S2, S3, S4, S5, S6) are arranged at respective first and second ends of a first (A), second (B) and third (C) of the 1-phase superconducting cables, and first connecting switches (S7, S9, S11) and second connecting switches (S8, S10, S12) are connected at a first and a second end, respectively, of the fourth (D) 1-phase superconducting cable. The interrupting switches (S1, S2, S3, S4, S5, S6) and the first (S7, S9, S11) and second (S8, S10, S12) connecting switches are operable to selectively disconnect one of the first (A), second (B) and third (C) one of the 1-phase superconducting cables from their respective current phase (L1, L2, L3) and to connect the fourth (D) 1-phase superconducting cable to the previously disconnected current phase (L1, L2, L3), effectively replacing the disconnected 1-phase superconducting cable.
