ELECTROINDUCTIVE APPARATUS Russian patent published in 2006 - IPC H01F30/16 H01F17/06 

FIELD: electrical engineering.

SUBSTANCE: proposed shell-core apparatus relates to ac transformers or line reactors designed for power conversion in electric circuits to control and regulate current and voltage in electric, lighting, and radio installations, as well as ballast and current-limiting resistors. Its core and side yokes are made in the form of hollow cylindrical magnetic circuits wound of magnetic strip and installed so that core-mounted winding or windings are disposed in space between outer side surface of core and inner side surface of side yoke. Core of each of transverse yokes is built of a number of trapezoidal parts distributed over butt-end surface of apparatus magnetic system and wound of magnetic strip; they function to close core and side yoke in directions radial with respect to core axis.

EFFECT: simplified design, facilitated manufacture, reduced height and magnetic material consumption.
