THREE-PHASE ELECTRIC REACTOR Russian patent published in 1996 - IPC

FIELD: electrical power engineering. SUBSTANCE: each phase of three-phase electric reactor includes individual closed magnetic circuit 1 with two rods 2, sections of main winding 3 and circuit 14 of current control of main winding. Circuit of current control of main winding is supplemented with thyristors 4. By change of enabling moment of thyristors one changes value of current determining value of biasing and of inductive resistance of reactor. Items of invention formula consider various variants of manufacture of circuit of current control of main winding with the use of diodes, additional thyristors and possible versions of their linking into star or delta connection. EFFECT: effective control over three-phase inductive resistors. 9 cl, 5 dwg
