ELEMENTARY MAGNETIC WIRING MODULE OF ELECTRIC TRANSFORMER, MAGNETIC WIRE CONTAINING THE MENTIONED ELEMENTARY MODULE, AND ITS MANUFACTURING METHOD AND TRANSFORMER, CONTAINING THE MENTIONED ELEMENTARY MODULE Russian patent published in 2018 - IPC H01F27/25 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. For this, the magnetic transformer module of an electrical transformer of tape type consists of first (1; 2) and second (3; 4) windings arranged one above the other, made respectively of a first and second material, with the specified first material is a crystalline material with saturation magnetization (Js) greater than or equal to 1.5 T, and with magnetic losses less than 20 W/kg for sinusoidal waves with frequency of 400 Hz and with maximum induction of 1 T, and this second material is a material with apparent saturation magnetostriction (λsat), less than or equal to 5 parts per million, and with magnetic losses less than 20 W/kg, for sinusoidal waves with frequency of 400 Hz and with maximum induction of 1 T, at the same section (S₁; S₂) of first winding (1; 2) and section (S₃; S₄) of second winding (3; 4) are such that the ratio (S₁ / (S₁+ S₃); S₂ / (S₂+ S₄)) each section of the first material with high saturation magnetization (Js) to the total cross section of both materials is from 2 to 50 %, preferably from 4 to 40 %.

EFFECT: technical result consists in reducing the loss of magnetic circuits.
