Definitions

  • the invention relates to a circuit arrangement for the windings of double-deck transformers, each with two electrically parallel-acting undervoltage and high-voltage main windings arranged spatially one above the other on common core legs and with coarse and / or fine-stage windings that can be connected to the high-voltage main windings by means of turners, selectors and load switches.
  • double-deck transformers are sometimes used instead of two separate transformers which are separate from one another, the nominal power of each floor of a double-deck transformer being equal to the nominal power of one of these single transformers.
  • the manufacturing and operating costs of these double-deck transformers lie between the costs for two single transformers, the nominal power of which corresponds to the nominal floor power, and the costs for a single transformer, the nominal power of which is the sum of the powers of the single transformers.
  • double-deck transformers have the advantage, however, that, like two single transformers, they reduce the short-circuit power in each of the networks connected to the undervoltage.
  • the invention is therefore based on the object of specifying a circuit arrangement for double-deck transformers which, when using only a single tap changer, precludes the occurrence of compensating currents between the tap windings of the two transformer storeys and, owing to the possibility of using a single tap changer, a space and Guaranteed inexpensive construction of double-deck transformers.
  • this object is achieved in that only one common coarse and / or fine-stage winding is provided for the high-voltage main windings of both transformer levels assigned to the same phase, that approximately equal parts of each of the stages of the step windings are arranged in each of the two transformer levels. that these parts of the step windings are each electrically connected in series and that the parts of the step windings that are common to the two transformer levels are connected together to a selector and a load switch and, if appropriate, to a turner.
  • the high-voltage master windings of the two transformer levels are electrically connected in parallel with one another and electrically in series with the step windings are.
  • the tapping of the fine-stage winding via the selector and the load switch, which carries the load current is expediently at zero potential and the series connection of the fine-stage winding halves takes place via a selector contact terminal.
  • the winding conductor cross-section in the step winding halves is twice as large as the winding conductor cross-section in the high-voltage master windings.
  • the circuit arrangement according to the invention is very advantageous because, at the same time, it allows a very simple construction of the windings, in particular the step windings, and only a single step switching device is required for their implementation.
  • Undervoltage windings 2 and 3 high-voltage master windings 4 and 5 and coarse and fine-stage windings are arranged around a core 1 which is layered in the usual manner from sheet metal.
  • the two low-voltage windings 2 and 3 like the two high-voltage master windings 4 and 5, are arranged spatially axially one above the other.
  • the two undervoltage windings 2 and 3 are completely electrically isolated from one another and serve to supply independent undervoltage networks.
  • the two high-voltage master windings 4 and 5 are electrically connected in parallel with one another and electrically connected in series with the step windings.
  • the coarse stage winding is made up of two coarse stage winding halves 6 and 7 and the fine stage winding is made up of parts 9 and 10 of approximately the same size for each of the stages.
  • One 9 of the parts 9 and 10 of each stage is on the upper floor and the other part 10 is arranged on the lower floor of the transformer.
  • the winding ends of the parts 9 are connected to the winding inputs of the parts 10 and both the winding ends of the parts 10 and the winding inputs of the parts 9 are connected to terminals of taps 11.
  • the coarse stage winding halves 6 and 7 and the parts 9 and 10 of the fine stage winding are each arranged spatially axially one above the other and thus represent winding tubes with very small radial dimensions. Both the coarse stage winding halves 6 and 7 and the parts 9 and 10 of the fine stage winding are due to their relatively low
  • the number of turns and the winding conductor cross-section which is about twice as large as that of the winding conductor cross-section in the high-voltage master windings 6, 7, can be easily manufactured in terms of production technology.
  • a turner -8 and a selector with load switch 12 are provided for the electrical connection of the coarse and fine stage winding.
  • the load line emanating from the load switch 12 is in the usual way, for example by grounding, at zero potential and forms a star point with the load lines emanating from the load switches 12 of the other phase. But it is also possible to connect the load lines to a delta connection.
