Definitions

  • the invention relates to a winding for a transformer or a coil with a band-shaped electrical conductors and with at least one band-shaped insulation material layer, which are applied to the electrical conductor or as tape material is placed on the conductor, which is namely the electrical conductor and the at least one band-shaped layer of insulation material, turns around one Winding core are wound along a winding axis.
  • the reversal can occur with comparatively narrow widths of the electrical conductor in that the winding angle at the axial end of the layer in question is continuously changed to a value of 90 ° and finally, e.g. B. after a another half turn is transferred in the desired winding direction.
  • a layer thickens radially at the ends and on the other hand there is a risk of wave formation with comparatively wide conductor strips and there may be kinks in the conductor tape. These adverse effects can be reinforced by the fact that the conductor strip is comparatively is thin.
  • the invention is characterized by a first layer of turns, which is radially adjacent to a second layer, by changing the winding direction by folding the electrical conductor and the at least one band-shaped Is insulating material layer can be generated, and that the resulting from the folding Total angle between the longitudinal direction of the ribbon-shaped insulating material first layer and the corresponding direction of the second layer double Corresponds to the winding angle.
  • An essential advantage of the invention is that the change in the winding direction of the electrical conductor to a radially adjacent to generate another layer, not by slowly changing it as was previously the case the winding direction, i.e. continuously, but by folding the electrical conductor.
  • more than one insulating layer together with the electrical conductor Windings can be wound on both sides of the electrical Conductor, as well as be arranged on both of its broad sides.
  • the risk of forming waves or kinks is also particularly great when the characteristic winding angle is less than about 85 °. According to the invention in this case, too, these adverse effects described are certain avoided.
  • the characteristic winding angle is that angle referred to, depending on the bandwidth of the electrical conductor and the The diameter of the winding of the layer in question is selected to ensure that is that the individual turns are arranged parallel to each other during the winding process are and such unwanted mechanical stresses in the longitudinal direction of the electrical Are safely avoided.
  • a further advantageous embodiment of the winding according to the invention characterizes is characterized in that an insulating layer between the first layer and the second layer is interposed.
  • a wave or crack formation is advantageously avoided and furthermore the advantage is achieved that voltage flashovers are avoided between the individual layers and also the surge resistance of the layers is increased.
  • the winding is further developed according to the invention if the folding on an axial End of a layer is arranged.
  • the folding of the electrical conductor is on any axial position possible, for example to produce radially adjacent layers, which, however, should have different axial lengths or two separate ones produce axially adjacent layers that are radially adjacent to another Location are arranged. Often, however, two neighboring layers should be the same have axial length. Then, as proposed according to the invention, the folding be arranged at the axial end of a layer. This is an optimal active axial length of a layer reached.
  • a two-layer winding of a transformer is shown in sections.
  • the winding is wound around a winding core 10 with a winding axis 12.
  • the winding is made of a band-shaped electrical conductor 14 which is connected to a band-shaped insulation material 16 is coated, formed.
  • the band-shaped insulation material 16 can also consist of a band-shaped film.
  • the first layer 18 of windings is the layer that is directly around the winding core 10 is wound. Between the first layer 18 and the winding core 10, an insulating layer 20 is arranged. The tape-shaped insulating material 16 is on the side of the electrical conductor facing away from the insulating layer 20 14, arranged. The individual turns of the first layer 18 are around a certain one Angle 22 inclined relative to the winding axis 12. Besides, everyone is Winding by a certain amount parallel to the direction of the winding axis 12 arranged offset from the previous turn, such that a next following Has a partial overlap with the previous turn.
  • a second layer 24 of turns is wound radially around the first layer 18.
  • the Layer structure of the second layer 24 corresponds essentially to the layer structure of FIG first layer 18, so that here too the electrical conductor 14 and the insulation material 16 in the form of an arrangement from turn to turn side by side with partial Overlap is designed.
  • the overlap in the second layer 24 is selected that an angle of attack 26 of the second layer 24 according to the amount determined Angle 22 corresponds, but with a negative angular orientation. That is, mathematically seen the angle of attack 26 corresponds to an angle of 180 ° minus of the determined angle 22, provided that the winding axis 12 is regarded as the zero angle becomes.
  • FIG. 2 shows a top view of a section of a transformer core 30 with the core axis 32 and a conductor strip 34 with the bandwidth 46. It is only a single turn of the conductor strip 34 partially shown.
  • the direction in which the winding of the winding is to take place is indicated by an arrow 36.
  • the arrow 36 is also intended to determine that position which, in terms of time, precedes one next following layer to be wound around the transformer core 30 and accordingly ends at the fold 38.
  • ends here is only meant that this location ends at this axial point. It can be easily that a radial adjacent position, which is arranged further inward around the transformer core 30, does not end at this axial point, but a longer axial area of the Transformer core 30 covered. In this case you have to wrap it on make sure that the current direction is correct and the electromagnetic effect of the do not cancel each other out.
  • the region of the conductor strip 34 just described has a winding angle 40 with the core axis 32.
  • the winding angle 40 should be the characteristic one Angle of this transformer core 30 be.
  • the characteristic angle depends on the bandwidth 46 of the conductor strip 34 and on the diameter the winding and therefore directly dependent on the geometry of the transformer core 30. If the characteristic angle is chosen as the winding angle 40, it is ensured that each turn is wound on the transformer core 30 is arranged parallel to its previous turn.
  • Typical bandwidths 46 for a conductor tape 34 are between 20 mm and 150 mm, while typical strip thickness for the conductor strip is approx. 0.1 mm to approx. 1 mm.
  • there the pairings of bandwidth and band thickness are not necessarily unique. Rather, a conductor strip with a bandwidth of 100 mm can be used depending on the load both with a tape thickness of 1 mm and with a tape thickness of 0.1 mm be designed.
  • the tape thickness can be the same with a tape width of 20 mm 0.1 mm, 0.5 mm or 1 mm. It is also within the spirit of the invention, choose any other combination of widths and thicknesses. Others too
  • the advantages according to the invention can be achieved in pairings.
  • the axial winding direction of the conductor strip 34 is to be changed. This happens by folding the electrical conductor tape 34 and an insulating film that the Conductor band 34 is assigned, but is not shown in this view.
  • the Folding takes place over the entire width of the conductor strip 34 along a straight line Line that is axially congruent with the dashed line 44.
  • the folding 38 a folding angle of approximately 180 °, so that the originally radially outer Side of the conductor strip 34 after folding the radially inner side, that is, is the side of the conductor strip 34 facing the transformer core 30.
  • the total angle 42 between the longitudinal direction of the conductor strip 34 before the folding 38 and the longitudinal direction of the conductor strip 34 after the folding 38 corresponds exactly the double winding angle 40.
  • the location of the fold 38 is thus both the end a certain position, as well as the beginning of the next following layer of turns.
  • the change in the winding direction is in contrast to the previously usual Windings, discontinuously at the folding point.
  • the fold 38 itself Experience has shown that there is no impermissible material stress for the material of the conductor strip 34 represents.
