IPC: H02G5/06
Filed: 1987-09-08
Abstract: PURPOSE:To reduce faulty current quickly upon short-circuit and prevent flux leakage to the outside upon normal time, by a method wherein an oxide superconductor is employed as a conductor while superconducting materials are stretched around on the whole inner surface of a housing. CONSTITUTION:An oxide superconductor 1, brought into a superconducting condition at the temperature of liquid nitrogen 3, is employed as the conductor of a separate phase bus (IPB). Superconductors 5 are stretched around on the whole inner surface of the housing 4 of the conductor.
