ELECTRIC MAGNETIZATION-CONTROLLED THREE-PHASE REACTOR Russian patent published in 1999 - IPC

FIELD: electric power transmission lines, in particular, for reactive power compensation. SUBSTANCE: device has three closed single-phase rod magnetic circuits each of which has two rods, as well two-compartment power winding and two-compartment control winding. Each rod carries compartment of power winding and compartment of control winding. Compartments of power winding which are located on each magnetic circuit are connected in parallel and are supplied by three-phase mains. Three compartments of control winding on same rods of three magnetic circuits are connected in series as open delta connection. Three compartment s of control windings of other rods of magnetic circuits are connected in parallel as second open delta connection. Both open delta connections are connected in parallel to controlled direct current biasing power supply. EFFECT: simplified design of windings, decreased usage of active materials, decreased number of direct current sources, improved harmonic composition of mains current which is output by reactor. 2 cl, 2 dwg
