Definitions

  • the invention relates to a transformer or a choke with layer-by-layer winding, in which taps are provided in a winding layer, in particular the outermost one.
  • a step transformer in which one embodiment has a fine step winding which consists of a plurality of solenoids or layers connected in series in the manner of a multi-start screw, of which only the outermost taps have taps.
  • Such windings are used for high voltages and lower currents and are easy to tap. The forces that occur when a short circuit occurs are therefore still relatively easy to control.
  • transformers or chokes in which the winding is wound with a number of turns per winding layer and several parallel conductors which are insulated from one another as a spiral winding with crossovers or twists, in which each conductor is guided in every winding position and all winding sections are provided with the same tap configuration.
  • the taps of the different winding sections are all provided in the same position in order to ensure the current distribution evenly over the parallel branches (wires) of the winding. Tapping in the external position has the advantage that the tapping points are easy to attach. A disadvantage, however, can be that the wires leading to the outside of the interruptions have to be fixed with special precautions or measures.
  • FR-A-1 147 646 now shows an externally similar winding structure to that according to the subject of the application.
  • a closer examination shows, however, that the winding shown is only a layer winding, which is carried out with parallel wires.
  • a disadvantage of such windings is that a high short-circuit strength is difficult to produce. Because of the fundamental differences in construction, the known winding structure cannot be transferred to the subject of the application.
  • German patent application A 10479 shows a transformer with layer-by-layer high-voltage winding and with taps, in which the outer winding layer carrying the taps is formed by a plurality of department coils placed one against the other, with their end points and their tap points are connected in parallel with each other.
  • this transformer winding too, there is no spiral winding, so that the solution according to the figure and the description of the design letter mentioned differs greatly from the subject of the application.
  • the transformers or chokes according to the subject of the application can be designed such that the winding sections are provided with four or more taps for connection to one or more changeover switches.
  • helical winding known per se, in which m parallel wires with a number of turns of n are exchanged cyclically in the order m, the necessary outcrossings and twists being distributed regularly over the height.
  • m-1 gaps of the appropriate width must be left blank. According to the invention, they are out Turning existing winding sections in a winding layer, and provided with several taps.
  • the individual wires a, b, c, d form the four winding layers, the wires being guided as a spiral winding with crossovers 5.5 ', 5 ". In each winding layer winding sections are thus constructed which each have turns.
  • the outer winding layer 6 also has four turn sections 7, 7 ', 7 ", 7'" Winding sections in the outermost winding layer are divided and provided with four taps 8-11 which, as shown for example in FIG.
  • Fig. 1 B the individual conductors are labeled a-b-c-d to illustrate the winding structure, each winding being labeled with the consecutive numbers 1 ... 32. It can be clearly seen that each conductor comes to lie in the outermost winding position and is tapped there with the taps 8-11. The outcrossings can be seen between turns 8-9 and 16-17.
  • FIG. 1C serves to further clarify the structure. From the development of the outer winding layer according to FIG. 1C, the figure shows a view with the connection points for the taps 8-11, an interruption 14 and a cross-out point 16. The image continues downward for the further winding sections. It can be seen that the wire sections, which can be seen in the plan view, for the turns 1-8 are formed by the conductors d; the subsequent turns 9, 10 ... are formed by the conductors a.
  • FIG. 2A shows a helical winding with the wires a, b, c, d, in which the taps 8 ', 9', 10 ', 11' are not applied in the outermost layer, but in a lower layer.
  • the winding configuration corresponds to that of FIG. 1A.
  • a corresponding diverter can therefore also be used.
  • Fig. 2C shows a sectional view along the line C ... C in Fig. 2B.
  • spacers 22 are attached distributed over the periphery of the winding cylinder. These spacers allow the wires of the taps 9 ', 10' to be guided to the outside and not to be squeezed.
  • a different number of taps can be made, e.g. B. six, as shown in Fig. 1 '.
  • the voltage values can be adjusted quasi-continuously.
  • FIGS. 4A and B show a cyclic spiral winding in which parallel wires of one turn are interchanged both in the radial and in the axial orientation and change places at fixed intervals by means of twists.
  • each of the eight wires being guided into the outer winding layer for approximately eight turns.
  • the conductor bundle has eight wires (branches) a, b ... h, in the example shown the branch d, which is on the outside, is first connected to the taps 18, 19. The twisting points are also shown. In the next winding section, a corresponding tap configuration is connected to branches c. This structure continues over the entire winding. It should be noted that in this case too, the wires lying in a lower winding position can be provided with taps.
  • FIG. 4B shows part of a development of a cyclic spiral winding, with taps 18, 19 being recognizable. The twists and interruptions are also clearly shown.
  • tapping connections are all mounted in the same winding position, it being ensured that each of the wires is guided in each winding position.
