FIELD: electrical engineering including cryogenic engineering; conversion of three-phase voltage of one commercial frequency to that of other frequency.
SUBSTANCE: proposed transformer incorporating superconductor windings has supporting structure, magnetic circuit built of internal core and external yoke, primary and secondary windings disposed on internal core and closed by external yoke, and cryostat. Superconductor windings are disposed on internal core, one on top of other; newly introduced in transformer are interphase jumpers and winding cooling ducts. External yoke is removable part mounted on glass-fiber laminate cylinder.
EFFECT: enhanced efficiency and manufacturability.
