FIELD: electrical engineering. SUBSTANCE: transformer includes magnetic core 1, magnetic shunt, screen composed of several parts 3,4,5,6,7,8 and 9. Parts 4 and 5 are made from sheet of current-conductive nonmagnetic material, for instance, copper, parts 6 and 7 - from solidified resin with high-frequency ferromagnetic filling agent, parts 3 and 8 - in the form of gauze of magnetically soft material, One part of screen is manufactured in the form of winding. Coil carrying primary 11 and secondary 12 windings is positioned on magnetic core. Presence of screen made of several parts improved interference immunity properties of transformer and reduces noises. EFFECT: improved interference immunity and reduced noises. 6 cl, 6 dwg
