TRANSFORMER MAGNETIC CORE (EMBODIMENTS) Russian patent published in 2018 - IPC H01F27/25 

Abstract RU 2656861 C1

FIELD: electrical equipment.

SUBSTANCE: invention relates to electrical equipment, to the transformers magnetic cores. In the first embodiment, the magnetic materials are wound in layers one on another in total number of n layers, with ratio of the magnetic material volumes in two adjacent layers equal to the ratio of the magnetic materials total volumes in n layers, which is determined by the formula: , where Vc2 – total volume of the second magnetic material in n layers; Vc1 – total volume of the first magnetic material in n layers; Bs1 – first material saturation induction; Bs2 – second material saturation induction; pc1 – first material specific losses; pc2 – second material specific losses. In the second embodiment, the magnetic core magnetic materials are stacked parallel to each other with a total number of n layers, with ratio of the magnetic material volumes in two adjacent layers, equal to the ratio of the magnetic materials total volumes in n layers, which is determined by the formula: , where Vc2 – total volume of the second magnetic material in n layers; Vc1 – total volume of the first magnetic material in n layers; Bs1 – first material saturation induction; Bs2 – second material saturation induction; pc1 – first material specific losses; pc2 – second material specific losses. Magnetic core design can be made three-rod or annular.

EFFECT: technical result consists in increase in the efficiency, achieving the magnetic materials volumes in the magnetic core optimal ratio and their effective distribution in the structure.
