TRANSFORMER(OPTIONS) Russian patent published in 1997 - IPC

FIELD: converter engineering; electric transformers. SUBSTANCE: transformer magnetic system is split into magnetic circuits 1 one part of whose legs is combined and other part of legs 5 is separated. Separated legs 5 carry turns of winding 2. Design options have different combinations of magnetic system and combinations of legs 4 and yokes: paired legs 4 to form, together with yokes, closed circuit with right angles; paired yokes mounted horizontally or vertically, using different types of laminations for same magnetic core 1; combining legs 5 with gaps, with movable core of ferromagnetic material, with turning winding relative to geometric axis of legs 5, with square- section legs 4,5 and windings 2,3. EFFECT: reduced mass and size of transformer due to reduced loss factor, facilitated manufacture, provision for unification, enlarged functional capabilities. 18 cl, 21 dwg
