SATURATION CHOKE Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: saturation choke has magnetic circuits manufactured from unsplit ring cores, packet of buses of working winding, main and additional insulation, members binding magnetic circuits in axial direction and supporting frame. Magnetic circuits are insulated from buses of working winding by additional insulation made in the form of strips put without clearance between packet of buses of working winding and unsplit ring cores. Members binding magnetic cores in axial direction are fabricated in the form of cross-arms anchored on buses of working winding and insulators of basic insulation are placed between cross-arms and supporting frame. Collecting bus can be used as supporting frame. Insulators of basic insulation in this case are arranged outside collecting bus. EFFECT: improved functional characteristics of saturation choke. 2 cl, 2 dwg
