Claim:
1. A device for influencing reactive power flows in a multi-phase alternating current system comprising a plurality of thyristor-controlled or thyristor-switched coil branches, in which a first coil branch is connected to a first phase and a second phase of the multi-phase alternating current system and a second coil branch is connected to the first phase and a third phase of the multi-phase alternating current system, and each coil branch comprises a first partial coil and a second partial coil, wherein the first and second partial coils are connected via first electrical terminals respectively to the corresponding phase of the multi-phase alternating current system and via second electrical terminals to a thyristor unit connected between the first and second partial coils, and the first partial coil of the first coil branch and the second partial coil of the second coil branch form a structurally independent first coil subassembly, each of the first and second partial coils are constructed hollow-cylindrically and a longitudinal mid-axis of the first and second partial coils in the structurally independent first coil subassembly is respectively oriented vertically with respect to a support plane, wherein the first partial coil has an inductance factor specifically dimensioned so as to be at least 10% greater than an inductance factor of the second partial coil, and the second partial coil in the structurally independent first coil subassembly is disposed structurally above the first partial coil and the weight of the second partial coil is supported by the first partial coil.
