| 摘要 |
The invention relates to a device (1) for influencing reactive-power flows in multi-phase alternating current systems, comprising a plurality of thyristor-controlled or thyristor-switched coil branches, each of which comprises a first partial coil (4, 4', 4") and a second partial coil (5, 5', 5"), a first partial coil (4, 4', 4") and a second partial coil (5, 5', 5") forming a structurally independent coil subassembly (13, 13', 13"). The essential feature consists in the inductance factor of the first partial coil (4, 4', 4") being especially at least 10 percent greater than the inductance factor of the second partial coil (5, 5', 5") and in the second partial coil (5, 5', 5") of a coil subassembly (13, 13', 13") being structurally arranged on top of the first partial coil (4, 4', 4") or the second partial coil (5, 5', 5") being structurally arranged in a core region of the first partial coil (4, 4', 4"). The disclosed device (1) for influencing reactive-power flows has a design that is as compact as possible, meets increased stability requirements especially for dynamic loads, and allows production costs and operating expenses to be reduced or kept to a minimum. |
