Definitions

  • the invention relates to a method for producing a winding arrangement of a coil, as well as an electrical conductor arrangement therefor and a winding arrangement produced by the method.
  • a coil for example a coil for a transformer
  • individual partial windings must be wound one after the other, which are then interconnected subsequently.
  • a special case is the so-called lintel winding.
  • the production of a coil with such a winding is quite complex.
  • DE-A1-32 14 171 shows such a winding arrangement.
  • the conductor used there consists of partial conductors that are connected in parallel and in series. There is no further information on the manufacture of the winding.
  • the invention has for its object to provide a method by which the manufacture of a coil can be simplified. Another object is to provide an electrical conductor arrangement for such a method and to specify a winding arrangement produced using the method.
  • the problem is solved with a method according to the features of claim 1.
  • a substantial time saving is achieved in the manufacture of the coil.
  • the winding of the coil can be done much faster than before. This applies in particular if a conductor, in particular a conductor arrangement, is used for which additional measures have already been carried out which were previously carried out during the winding process. This applies, for example, to the insertion of intermediate layers for insulation between windings or edge protection.
  • the process is also suitable for complex nested windings.
  • At least part of the conductor arrangement is wound onto the winding body to form a disk winding. Particularly high savings in production are possible here, since at least two disc coils are created during the winding process. If more than two conductor pieces overlap one another in a section of the conductor arrangement, several turns can be generated simultaneously with one winding rotation.
  • a lintel winding step can advantageously follow. It is advantageous if the ends of mutually overlapping conductor pieces are electrically connected to one another in a further step. In this way, the conductors are not cut to length later, which also reduces the risk of injury to the already finished winding. There are clean connection points on the coil.
  • the respective conductor pieces can comprise a plurality of conductor wires connected in parallel, wherein the conductor pieces can also be designed as twisted pairs.
  • the conductor arrangement is also suitable for applications in the energy sector, for example for high-voltage transformers.
  • connection points are therefore precisely specified.
  • the conductor pieces can advantageously be separated from one another by spacer inserts. This eliminates the time-consuming intermediate winding of spacer inserts or edge protection rings when winding the transformer, as was previously the case. This applies in particular to the inside of a coil.
  • conductor 1 shows an electrical conductor arrangement, hereinafter referred to as conductor 1, for a winding arrangement, which consists of a plurality of conductor pieces 3a to 3e.
  • the conductor pieces 3a to 3e are at least partially overlapping one another, but are connected to one another in an insulated manner, so that a type of prefabricated conductor is provided.
  • the lengths of the conductor pieces 3a to 3e are specified in such a way that, when a coil is being wound, conductor sections A to D are each assigned predetermined windings.
  • the free ends of the conductor pieces 3a to 3e are optionally dimensioned such that they can be electrically connected to one another after winding. In the present FIG.
  • the cross section shown in FIG. 2 of the conductor 1 from FIG. 1 along the line II-II represents a simple embodiment variant.
  • the conductor labeled la has two conductor pieces 3c, 3d which are insulated from one another by the intermediate layer 9c.
  • the conductor pieces 3c, 3d are surrounded by a common insulation 7c.
  • the conductor pieces 3c, 3d can comprise one or more conductor wires, for example as a solid conductor or a stranded conductor. This version is particularly space-saving, since it can be used to produce a very tightly and compactly wound coil which has very small dimensions.
  • the cross section shown in FIG. 3 shows a preferred variant of the conductor 1 from FIG. 1.
  • the conductor labeled 1b has two conductor pieces 3c and 3d each surrounded by separate insulation 11a, 11b. As indicated in the drawing, these are designed as a concatenated twin wire. An intermediate layer 9c is arranged between them and is designed to determine capacity.
  • the conductor pieces 3c, 3d are surrounded by the common insulation 7c. In the present embodiment, this can optionally be made thinner than in the embodiment according to FIG. 1.
  • a function of the common insulation 7c is to hold the respective conductor pieces together or to connect them to one another. It is essential that Because of the common insulation 7a to 7d (FIG. 1), the edge protection rings used in the prior art for electrical reasons (surge voltage level) can be dispensed with.
  • FIG. 4 shows a partial external view of a winding arrangement 12 in which the conductor 1 according to FIG. 1 is used.
  • the winding arrangement 12 is designed as a coil with a drop winding.
  • the conductor sections A, B, C and D each form disk coil pairs 13a, 14a to 13d, 14d.
  • the free ends 5a, 5b of the end-side disc coils 13a and 14d form the connections for the winding arrangement 12.
  • the individual disc coils 13a to 14d are separated from one another by spacer inserts 15.
  • the area of the winding arrangement 12 is now shown on which the connections between the conductor pieces 3a to 3e are made.
  • the free ends 5c, 5d of the conductor pieces 3c and 3d form a connection between the two disk coils 13c and 14c of the conductor section C.
  • the transitions 6a to 6c which are each formed by the conductor pieces 3b to 3d, come thereby to lie between the respective disk coils of two adjacent conductor sections, for example transition 6c between the conductor sections D and C with the disk coils 13d and 14c.
  • a further connection point between the disc coils, which are arranged next to one another, is (not shown in more detail), as is customary in the case of drop windings, on the inside of the winding arrangement 12.
  • Such a transition point corresponds in FIG. 1 to the respective centers of the conductor sections A to D.
  • the intermediate layers 9a to 9d are preferably used in thicknesses between 0.1 to 2 mm, in particular 0.3 to 1 mm. Voltage stresses between 50 and 150 KV are taken into account.
