Definitions

  • the invention relates to a transformer winding comprising at least two hollow cylindrical axially adjacent winding modules arranged around a common winding axis with a layer-wound electrical conductor and a common electrical insulation layer, by which the winding modules are enveloped.
  • both winding modules 12, 14 are surrounded by a common insulation layer 22, in this case a wound insulating material preimpregnated with an B-stage epoxy resin, which was finally heated to a polymerization temperature.
  • the insulating layer 22 not only surrounds the outer surfaces of the winding, but it is also provided between them also between the individual winding layers and thus ensures the electrical insulation between the wound conductor layers.
  • winding 42 which is intended to symbolize a winding on the low side
  • radially outer winding according to the invention is intended to symbolize a winding on the high side with a rated voltage of, for example, 60 kV.
  • an extension according to the invention of the creepage path is not essential because of the lower voltage load associated with a lower rated voltage of, for example, 6 kV.
  • Fig. 2 shows a complete section through a second exemplary transformer winding 50, ie with a partial section above the winding axis 50 and a partial section below the winding axis 56.
  • a second exemplary transformer winding 50 ie with a partial section above the winding axis 50 and a partial section below the winding axis 56.
  • Arranged around the winding axis 56 are two hollow cylindrical and axially adjacent winding modules 52, 54, each indicated by five winding layers are.
  • the galvanic connections of the layers to each other and the galvanic connection between the winding modules 52, 54 are shown, while only the winding layers are shown in the lower section.
  • the two winding modules are surrounded by a common insulation layer 68.
  • radial outer surface of the insulation layer 68 Arranged on the radial outer surface of the insulation layer 68 are five ring-shaped radial depressions 58, 60, 62, 64, 66, which serve to extend the creeping path. Depending on the structural boundary conditions, depressions prove to be more advantageous over surveys, because they have no additional space requirement and also allow material savings.
  • the respective radially outer two winding layers are axially reset in the axial center of the winding 50, so that the annular radial recess 58 could be correspondingly deeper and larger than the other wells 60, 62, 64, 66. This proves to be particularly advantageous because in the axial space between the two winding modules along the outer surface of the insulating layer operatively even with the highest voltage stress is calculated. Therefore, the extension of the creepage path advantageously correlates with the local stress loading.
  • Fig. 3 shows a section through a portion of a third exemplary transformer winding 70 which is disposed about a winding axis 80.
  • the winding is essentially the same as in Fig. 1
  • four axially adjacent winding modules 72, 74, 76, 78 are provided, which are divided into two galvanically interconnected subgroups of the winding modules 72 and 74 and 76 and 78, wherein the groups in turn galvanically from each other are separated.
  • the winding modules 72, 74, 76, 78 are surrounded by a common insulation layer 82 or enclosed therein.
  • the highest stress loads along the radially outer surface 90 occur in the axial direction between adjacent winding modules 72, 74, 76, 78.
  • These are also exactly the areas where the creepage distance has been lengthened in the axial direction by corresponding radial ring-like depressions 84, 86, 88, so that a correspondingly increased dielectric strength results.
  • Another Kriechwegverinrung in the region of the adjoining sub-groups 72, 74 and 76, 78 is realized by protruding from the insulating material flexible profile strips 90, 92, 94, wherein the arranged in the recess 86 profile strip protrudes only from the bottom of the recess, but not from the winding surface.
  • the profile strips are made of an electrically insulating material such as a silicone rubber.
  • the T-shaped profile strips are fixed by a plurality of the transverse T-bar enclosing layers of a wound insulation material.
