SUPERCONDUCTING HYBRID TRANSFORMER Russian patent published in 2024 - IPC H01F36/00 H01F27/28 H01F27/36 H01F6/06 H02K55/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to transformer windings, and can be used in power engineering related to cryogenic electrical engineering. Superconducting hybrid transformer includes a magnetic conductor, a cryostat, power multilayer cylindrical high and low voltage windings with concentrically arranged layers of turns, which are in dielectric cryogenic medium of liquid nitrogen and are located one above the other for each phase. Low voltage winding is made of superconducting conductor. High-voltage winding is made of metal or metal alloys. High-voltage winding is located above the low-voltage winding along the rods of the magnetic conductor. Between the windings there is a screen made of diamagnetic or superconducting material.

EFFECT: increase of current density in windings, efficiency of transformer and reduction of electric power losses and weight and size characteristics of the transformer.
