FIELD: electrical engineering.
SUBSTANCE: multi-phase magnetic system of electrical equipment, the material of which is an electrical steel sheet or roll. The three-phase spatial laminated magnetic core contains three identical annular segments, which are connected in pairs to form three cores of the magnetic core with circular cross sections. In this case, the annular segment consists of sheet flat elements, each of which is a rectangle with a rectangular window and has dimensions described by a parametric dependence.
EFFECT: increasing the power of the produced three-phase spatial magnetic cores for industrial transformers with a current frequency of 50 Hz while maintaining increased efficiency and reliability of operation during long-term operation.
