Problems solved by technology

But this known device takes more space due to these additional components and is expensive
Furthermore, the adjustment possibilities of this known device are also limited, since its impedance cannot be reduced to zero but only to the impedance of the parallel connected coils 2 and 6

Embodiment Construction

[0042] figure 2 shows an embodiment of a device 8 according to the invention, which can be achieved by figure 2 The switch, which cannot be seen in , is connected to the high voltage line 9 that transmits power between two nodes of the electrical energy distribution network. The device 8 is therefore arranged in series in the high-voltage line 9 in such a way that all the alternating current conducted via the high-voltage line 9 passes through the device 8 . As usual, the high-voltage line consists of three phases, ie three high-voltage lines through which current flows in succession, of which only one phase is shown in the figure for the sake of clarity. The other phases, not shown, of the high-voltage line 9 are connected to the device 8 in the same manner as the phases shown in the figure. Correspondingly, the device 8 can of course also be connected to a high-voltage line having more or less than three phases.

[0043] The device 8 has a regulating coil 2 and a switch...

Abstract

The invention relates to a device (8) for adjusting the impedance of a high-voltage line (9) conducting alternating current, comprising at least one adjusting coil (2) which can be connected in series in the high-voltage line (9) and at least one respectively assigned adjusting coil ( 2) Switching devices (3, 10), wherein a control unit (4) is provided for controlling each switching device (3, 10), the regulation acting on the device can be adjusted by switching on the switching devices (3, 10) The reactance of the coil (2). In order to provide such a compact and inexpensive arrangement, it is proposed to arrange each switching device ( 3 , 10 ) in parallel with its associated control coil ( 2 ) in a parallel branch ( 5 ).

Description

technical field [0001] The invention relates to a device for adjusting the impedance of a high-voltage line that conducts alternating current and is composed of multiple phases, having at least one regulating coil that can be connected in series in the high-voltage line and at least one switching device that is each assigned to the regulating coil. A control unit is provided for controlling each switching device, the reactance of the control coil acting on the device can be adjusted by switching on the switching device. [0002] Furthermore, the invention relates to a method and a control unit for adjusting the impedance of a high-voltage line carrying alternating current. Background technique [0003] One such device, method and control unit is disclosed, for example, in DE 3787335 T2. The device disclosed therein is attached figure 1 shown in . This known device 1 has a regulating coil 2 and a non-regulating coil 6 which can be passed through figure 1 Connectors or swi...
