CURRENT TRANSFORMER Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: current transformer has sectionalized primary winding 1 composed of four single-turn V-shaped sections which presents multiturn loop. Winding holder is employed to support primary winding 1 in vertical position and to ensure tight fitting of loop of primary winding to secondary winding 3. Bottom of oil conservator 14 has window of rectangular shape which smaller size is lying on axis of line leads 19, 20. Bearing plate is placed in bottom of oil conservator 14 transverse to window with the partial overlapping. Steel bolt 7 of winding holder rests against bearing plate. EFFECT: reduced usage of metal, increased electrodynamic stability to currents of short-circuits. 9 cl, 15 dwg
