MANAGED REACTOR WITH MAGNIFYING FROM PERMANENT MAGNETS Russian patent published in 2017 - IPC H01F29/14 H01F21/06 

FIELD: electricity.

SUBSTANCE: reactor with magnifying contains a main winding, a magnetic system with yokes and rods. The reactor rod is T-shaped with an internal cavity having a constriction. Inside the cavity there is a permanent magnet with the possibility of moving along the axis of the rod. The yokes are L-shaped, and non-magnetic gaps are made between the ends of the yoke and the rod. The change in the magnetic state (the degree of magnifying and saturation) of the narrowed sections of the rod is carried out by the displacement of a permanent magnet in the cavity of the rod.

EFFECT: reduction of overall dimensions, consumption of active materials, losses to magnifying, expansion of the adjustable range of change in inductive resistance of the reactor.
