BOOSTER FOR AC ELECTRIFIED RAILWAY Russian patent published in 1994 - IPC

FIELD: electrified railways. SUBSTANCE: booster has primary winding connected to traction transformer and secondary windings having equal number of turns and equal capacities. Two separating reactors have two coils each with common point. Numbers of turns and capacities of coils are equal. Capacitor bank is connected in series with inductive reactor. Starts of secondary windings of right core are connected to bus lead-out of traction winding and to first coil of first separating reactor and finishes of windings of first core are linked to finishes of windings of left core, to first coil of second separating reactor and to second coil of first separating reactor. Starts of windings of left core of transformer are connected to second coil of second separating reactor and to feeder of contact system. Capacitor bank and inductive reactor are connected to common leads of coils of first and second separating reactors. EFFECT: 15-30% reduction of losses, full compensation of loss of voltage caused by inductive component of load current. 2 cl, 3 dwg
