Abstract
The invention discloses a controllable reactor with orthogonal magnetic rings. Each iron core column, side column or iron yoke is formed by alternatively laminating a plurality of magnetic ring modules and a plurality of cushion blocks which have the same or different shapes and sizes. Each magnetic ring module consists of iron magnetic materials and orthogonal control windings which are wound on the iron magnetic materials. The orthogonal control windings and the cushion blocks are arranged on a plane of the magnetic ring module alternatively. The inner and outer circles of the cushion blocks are arranged along the radial direction of the plane of the magnetic ring module, or one or more circles of the cushion blocks are arranged along the radial direction of the plane of the magnetic ring module. When the orthogonal control windings work in an alternating current supply way, the winding directions of adjacent windings are opposite; and when the orthogonal control windings work in a direct current supply way, the winding directions of adjacent windings are the same or opposite. By changing current of the control windings and a magnetic field, which is produced by the orthogonal control windings and is vertical to main flux, in the magnetic ring modules, the magnetic conductivity of the iron cores of the magnetic rings is changed, so reactance values of alternating current work windings are changed.
