POLYPHASE TRANSFORMER

摘要

electrical engineering. SUBSTANCE: given polyphase transformer is designed for use in polyphase semiconductor converters of electric energy. Two side stranded ring magnetic cores bordering on butt surfaces of center magnetic core come without grooves and three-phase primary and multiphase secondary windings are dropped in slots between twisted teeth cemented on butt surfaces of center magnetic core. EFFECT: simplified manufacturing technology, reduced usage of electrical-sheet steel, improved quality of energy conversion. 2 dwg
