NOISE-RESISTANT TRANSFORMER Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: noise-resistant transformer has magnetic circuit 1, screen consisting of parts 2 and 3, primary winding 4 connected to mains through leadings 5, secondary winding 7 connected through lead-outs 8 to load 9; windings 4 and 7 are poured into shell 10 made of resin with filler. Screen has two relatively orthogonal parts 2 and 3 made up of sheet magnetic material. Part 2 of screen has radial cut 11 shunted by resistive element 12. Both parts of screen are connected by magnetic shunt 13. EFFECT: enhanced reliability of operation. 6 cl, 6 dwg, 1 tbl
