FIELD: manufacture of transformers, multiphase semiconductor converters of electric energy. SUBSTANCE: center twisted magnetic core of multiphase transformer comes in the form of ring, slots accommodating windings embracing it are formed by V-shaped teeth, so built-up from laminations of cold-rolled electrical-sheet steel that direction of rolling is perpendicular to face surfaces of center magnetic core. EFFECT: simplified manufacturing technology, reduced waste, increased efficiency and improved quality of conversion of electric energy. 2 dwg |
