THREE-PHASE ELECTRIC REACTOR WITH MAGNETISATION Russian patent published in 2008 - IPC H01F38/02 H01F37/00 H01F29/14 

FIELD: FILED: electric engineering.

SUBSTANCE: invention is related to the field of electrical engineering and may be used in magnetisation-controlled reactors, which are installed, for instance, in electric circuits as shunting reactors for compensation of reactive power parallel to capacitor battery, etc. Three-phase electric reactor contains magnet system with six rods, with upper, lower and two side yokes. Control windings are installed in every rod. Three leads are intended for connection to three phases of the grid, and neutral lead, plus and minus leads - for connection to controlled source of DC (CSDC). Grid windings with some taps are connected to three leads of three phases in pairs, and with the other ones - to neutral lead and are installed at every rod. Windings of the first and fourth rod are connected to the lead of one phase, of the second and fifth rod - to the lead of the other phase, of the third and sixth rod - to the lead of the third phase. Beginning of control winding of the first rod is connected to the plus lead of CSDC, and the end - to the beginning of control winding of the fifth rod. End of control winding of the fifth rod is connected to the beginning of control winding of the third rod and one supply lead of CSDC. End of control winding of the third rod is connected to the minus lead of CSDC. Beginning of control winding of the sixth rod is connected to the minus lead of CSDC, and the end - to the beginning of control winding of the second rod and the second lead of CSDC supply. End of control winding of the second rod is connected to the beginning of control winding of the fourth rod, and end of control winding of the fourth rod - to the plus lead of CSDC.

EFFECT: expansion of functional resources and increase of reliability by means of autonomous arrangement of magnetisation supply source, reduction of active materials consumption and losses due to optimal connection of grid control windings.
