Definitions

  • the invention relates to an electrical device for connection to a high-voltage network with a housing which can be filled with a cooling liquid, a core in the housing angeord ⁇ Neten of a magnetizable material, a parent winding, which encloses a portion of the core, a Re ⁇ gelwicklungsen or prevented ⁇ light with control windings, each enclosing a section of the core, and a switch enabling a current flow through each control windings optional.
  • Such an electrical device is known in practice.
  • a reactor is used in electrical distribution networks, in order prepared, for example, capacitive reactive power to kompensie ⁇ ren.
  • the choke off with a load tap changer can be connected with the turns of a regulating winding group of a main winding. So far, the maximum achievable reactive power setting for such a throttle, for example, was about 60% in a 420kV grid, based on their maximum operating performance. Due to the increasing fluctuation of the reactive power in the supply network, however, it is desirable to be able to control the reactive power in the network over a larger range.
  • the object of the invention is therefore to provide an electrical device of the type mentioned, which increase a reactive power setting.
  • the reactive power adjustment range based on the maximum power of the electric device at a voltage of 420 kV should be greater than 60% S ⁇ .
  • the invention solves this problem in that the rule winding group has a first rule winding subgroup and a second rule winding subgroup, wherein the first Regelwicklungsunteren and the second Cannabiswicklungsunter ⁇ group are identical to each other.
  • two control subgroups are provided for providing a larger adjustment range of the reactive power, which have a structure which is identical to one another. Doubling the control winding groups provides the additional turns necessary to increase the tuning range.
  • the first control sub-group and the second control sub-group are arranged in the housing of the electrical device such that the predetermined boundary conditions are maintained in the space bounded by the housing.
  • These predetermined boundary conditions include, for example, the maximum permissible leakage reactance limited by the switch between each coarse and fine stage pair of the switch, which may not be exceeded in order to enable safe operation of the electrical device.
  • the leakage reactance can be determined by conventional means known to those skilled in the art. For example, two windings arranged side by side, the stray reactance ⁇ from measurements of the short-circuit impedance of both windings can be determined.
  • the rule winding subgroups preferably each have at least one coarse and at least one fine stage.
  • the switch is, for example, a commercially available on-load tap-changer.
  • a coarse stage is a winding with more turns than a fine stage.
  • the fine stage can be subdivided into several fine-stage subunits. Switching on a coarse level changes the reactive power in the grid more than switching on a fine stage.
  • coarse, fine and coarse winding or fine winding are used synonymously here.
  • the control winding subgroups are arranged in an inventive manner in the main winding in the housing of the electrical device common to all windings.
  • the parent winding encloses a core section extending in the axial direction.
  • the said core section is, for example, a leg of a core.
  • the main winding comprises a first winding, which is set up for direct connection to the high-voltage network.
  • the first winding is connected via a winding-free conductor section to a high-voltage connection of the electrical device.
  • This high-voltage connection is, for example, an expedient feedthrough whose high-voltage conductor is connected at its winding end to the first turn.
  • an outdoor connection is formed at the side facing away from the winding end of the high-voltage ⁇ implementation example.
  • the respective trunk ⁇ winding is connected to a phase of a high voltage network.
  • the first control winding sub-group and the second control winding sub-group in this embodiment of the invention He ⁇ in said axial direction one above the other arranged beab- standet and enclose a portion of the Kernab ⁇ section, the winding surrounds the stem.
  • the control winding subgroups are each shorter in the axial direction and preferably each formed slightly less than half as long as the main winding. Therefore, the axially stacked übereinan- the control winding sub-groups include in total the same core section, so crizspielswei ⁇ se the same leg region as the main winding.
  • the parent winding encloses a extending in the axial direction core portion, wherein the first turn is set up for direct connection to the high-voltage network.
  • the first turn is connected to the high-voltage connection of the electrical device via an unwound winding-free conductor section.
  • the first control winding sub-group and the second control winding sub-group in each case surround the same core section as the main winding, where ⁇ are also arranged for the main winding at the first control winding sub-group and the second control winding sub-group concentric with each other and so ⁇ with naturally.
  • the control winding subgroups each have a coarse and a fine step
  • the said sequence can also be coarse, fine, coarse, fine.
  • the leakage reactances can be limited to a permissible level, so that it can lead to a fault-free operation of the electrical device and in particular of the switch.
  • the main winding encloses a extending in the axial direction of the core portion, wherein a mean turn is set up for direct An ⁇ conclusion to the high-voltage network.
