Abstract

FIELD: electrical engineering; static energy converters. SUBSTANCE: apparatus uses rectangular-section box shaped hollow spatial magnetic circuit in the form of regular hollow polygon assembled of electric steel stacks with inserts in the form of regular hollow polygons wound of electric steel band that function to reduce leakage flux in mating joints. Apparatus makes it possible to obtain single-phase, electromagnetically isolated transformers on single magnetic circuit which enlarges its functional capabilities. EFFECT: improved reliability due to reduced bending radius of conductors of internal pair of transformer windings, facilitated manufacture, reduced leakage flux at joints, reduced unbalance of orthogonal magnetic fluxes and magnetizing currents, enlarged functional capabilities. 8 dwg

e. The purpose of the invention is to increase reliability by reducing the bending of the wires of the inner pair of transformer windings to more than 90 °, simplifying the manufacture of the inner pair of windings, reducing the scattering fluxes at the joints, reducing the asymmetry in the magnitude of the orthogonal magnetic fluxes and magnetizing currents. This goal is achieved by using a rectangular box-shaped hollow spatial magnetic core in the form of a regular hollow polygon from sets of electrical steel, having inserts in the form of regular hollow polygons wound from electrical steel tape, which reduce the scattering fluxes in the mating joints. The device allows you to get on the same magnetic circuit two single-phase transformers that are not electromagnetically connected to each other, which allows to expand its scope.
