Definitions

  • the invention relates to a winding for an air-cooled dry-type transformer or a choke coil, in which circumferential air channels between at least two winding layers are kept open by rod-shaped spacer elements which are distributed over the circumference in the axial direction or obliquely thereto.
  • the invention is accordingly based on the basic idea of replacing the full profile spacer elements with those that do not have a full profile, but rather a web profile that is open at least on one side.
  • Such spacer elements can be produced from plastic by extrusion.
  • the support legs can lie parallel to one another and, in cross section, form an H or N configuration together with the connecting web.
  • the or ⁇ configuration has the advantage that the top and bottom are the same when inserted.
  • the ⁇ configuration again leads to a somewhat greater strength, since the connecting crossbar forms a kind of roof.
  • the spacer elements can, for example, be applied to an auxiliary carrier provided with an adhesive layer. It is also possible to connect them to one another at their free ends or in other areas via a spray skin or a thin film.
  • the film should be so thin or appropriately perforated that it can easily be torn again.
  • the partial winding which is shown in Figure 1, is made of winding wire or foil winding, as is known as the prior art.
  • the spacer elements 3 are designed as an open profile, the cross section having a configuration.
  • the configuration consists of two support legs 4, 5 which are parallel to one another and are rigidly connected to one another with a connecting web 6 lying perpendicular thereto.
  • the wall thickness of the support legs is about 5 - 20% of the cross-sectional width or height.
  • This shape of the spacer elements enables the Cross section of the spacer element is used for the heat transport by the cooling air, while at the same time a relatively dense covering of the circumference with spacer elements is possible to increase the strength.
  • the covering of the cross section with winding material be it wire or be it foil, can be increased.
  • the spacer elements can be connected to one another at their feet or free ends 7 with a fine spray skin 8, so that insertion is facilitated. Instead of a spray skin, another thin film, which is advantageously easy to tear, can be used.
  • the spacer elements are preferably made of plastic in the extrusion process or of glass fiber reinforced plastic, the preferred fiber direction being in the element axis direction.
  • FIGS. 2 a) to d show a cross-sectional shape similar to that in FIG. 1.
  • the support legs 4, 5 end in foot-like widenings 9.
  • the spacer elements have stiffeners 10. In the present case, these stiffeners are thickened portions of the plastic mass used.
  • the cross-sectional shape shown in FIG. 2 a) is therefore suitable for absorbing a greater load than the profile of FIG. 1.
  • FIG. 2 b shows a cross-sectional shape in which the support legs 4 b, 5 b diverge towards the free ends 9 b, the ends which are close to one another being connected to one another by a connecting web 6 b. This results in a trapezoidal shape in cross section. If the web 6 is omitted and a corresponding one Inclination of the legs 4 b, 5 b selected, a V-shape can also result.
  • Figure 2 c shows a so-called H configuration, in which the support legs 4 c, 5 c are parallel to each other and are connected approximately in the middle by a connecting web 6 c.
  • This configuration has the advantage that the top and bottom can be interchanged during assembly.
  • FIG. 2 d shows a configuration in which the support legs 4 d, 5 d are parallel to one another and are connected to one another by an arch 3 d instead of by a straight web.
  • an arch can deflect the applied forces particularly well to the sides.
  • the height and length of the support legs in relation to the connecting webs or the bend results from the necessary distances of the winding layers to be cooled or from the heat dissipation necessities known to the person skilled in the art for a certain electrical winding power. Otherwise, the proportions of the parts relative to one another can be read from FIGS. 1 and 2.
  • the new spacer elements are inserted and attached, as is known.
  • auxiliary spacer elements during the winding and to remove them again after the winding has hardened.
  • glue the spacer elements onto a carrier film and to attach them in the desired arrangement within the windings.
  • the spacer elements can be introduced within the high-voltage, low-voltage winding or inserted between the high and low-voltage winding.
