DEVICE WITH THREE SUPERCONDUCTING PHASE WIRES Russian patent published in 2015 - IPC H01B12/16 

FIELD: electricity.

SUBSTANCE: invention relates to the device with three superconducting phase wires which are located, at least, in one coolant-passing cryostat consisting of, at least, one tube with thermal insulation and which is made from a superconducting wire, and also dielectric and conductive screen around it. The screens (S1, S2, S3) of all three phase wires (1, 2, 3) for forming of three - or integer 3 multiple sections (A1, A2, A3) located one after another in their longitudinal direction with partial screens - the first, second and third section, are completely disconnected in two or respectively two, located at distance from each other, places. The partial screen of the first section of each phase wire is series connected to partial screens of the second and then the third section of both other phase wires, and screens (S1, S2, S3) of three phase wires (1, 2, 3) consist of normally conducting material, in particular, of copper.

EFFECT: invention provides design simplification and decrease of losses connected with transmission to phase wires.
