Definitions

  • the invention relates to a winding for a transformer, in particular a high-voltage winding for a transformer, and to a method for producing the winding.
  • a winding for a transformer or a coil for such a transformer is composed of one or more band-shaped conductors and an insulating material layer of band-shaped insulating material, which are wound together in turns around a winding core.
  • the individual turns of the winding have a predetermined winding angle with respect to the winding axis of the winding core and are arranged to each other with partial overlap, wherein between two radially adjacent layers of turns of electrically conductive material, an insulating layer is inserted.
  • a layer or it can also be provided several layers of turns of electrically conductive material, which layers that lie radially above one another, form a multilayer transformer or a multi-layer coil.
  • the insulating layer between the conductors prevents voltage flashovers between the layers and is thus designed for the largest occurring voltage difference between two layers.
  • the insulating material is wound in a stepped manner, so that the thickness of the insulating material changes in the axial direction.
  • the insulating layer at one axial end of the coil is thicker than at the other end, wherein the insulating layer between the two following layers of electrically conductive material at the point has a greater radial thickness at which the The first layer is thinnest, while the other end of the layer is in the region where the underlying layer is thickest.
  • the conductor material and the insulation for the winding is simultaneously applied (simultaneously) or wound up.
  • the roving fibers for the insulating layer may be formed circumferentially and at an angle to the winding axis (radial bandages and cross dressings).
  • the object of the invention is to provide a layer insulation, in which a force is also provided in the axial direction.
  • the insulating material may be either a glass or a polyester roving, which is impregnated with casting resin. However, the insulating material may also be impregnated with a resin in the so-called B-state in which the resin is still liquid, possibly with expanding filler. As insulation materials could also Nonwovens or fabric tapes are used.
  • the term "fiber rovings" therefore includes all possible suitable and similar acting materials.
  • the layers of insulating material are applied at an angle to the winding axis.
  • the layers of insulating material can thereby be applied, that the coil is moved past the feed point; Of course, there is also the possibility that the feed point is moved relative to the fixed coil.
  • the fiber roving feed can then be moved back and forth in the direction of the winding axis.
  • Fig. 2 shows the orientation of a Isoliermaterialbandes according to the invention
  • Fig. 3 is a schematic representation of a standard equipment of a strip of tape made of insulating material.
  • a first radially inner layer 12 of conductor material is wound, which layer of several layer sections 13, 14, 15 ... is composed, wherein the individual bearing portions 13, 14, 15 overlap.
  • a conductor material here a conductor strip material is shown.
  • conductors with a round or rectangular cross-section could also be used. In that regard, the invention is not limited to conductor strip material.

In between there are several stages 17, 18 and 19, depending on the axial length of the winding, which has been given the reference numeral 20 in total.
  • the layer 16 of insulating material On the layer 16 of insulating material is a radially outer second layer 21 of electrically conductive material, which is formed in the same way as the layer 16; the applied thereto outer layer 22 of insulating material is constructed in a similar manner as the layer 16, wherein, however, the radial thickness D 3 is in the range in which the layer 16 is located with the largest thickness D 2 ; At the other end, located on the right-hand side, the position of the insulating material has the radial thickness D 4 , steps 23, 24, 25 being provided here as well.
  • the radial thickness of the insulating layers 16 and 22 is designed according to the voltage difference between two layers of conductive material.
  • roving strip 30 of insulating material is wound in such a way that the roving strand 30 runs exactly in the circumferential direction, which represents a standard embodiment and is state of the art to that extent.
  • a strip 32 of electrically insulating material, here a roving strip, which extends at an angle ⁇ to a plane E perpendicular to FIG. 2 is applied to a bobbin 31 or a coil 31 to the longitudinal axis MM of the coil 31 extends.
  • the roving 32 can be moved back and forth, so that as shown in phantom with 32a, the angle ⁇ extends on both sides to a plane which is aligned perpendicular to the central axis MM.
  • the roving band can be wound in a zigzag orientation on the coil 31.
  • the angle ⁇ there is also the possibility that, depending on the design of the angle ⁇ , the assignment of the belt 32 to the coil 31 always runs in the same direction, as shown in the drawing Fig. 2.
  • the back and forth of the support according to the direction of arrow P can of course be designed so that in addition to a stepped insulation, a straight, wedge-shaped insulation can be made.
  • the residence times of the insulation support at locations with thick layer insulation to choose greater, which of course is also the case with the graded insulation layers.
  • an approach to the straight wedge-shaped insulation would be possible with a larger number of stages.
