Definitions

  • the invention relates to a method for producing a winding arrangement of a coil, and an electrical conductor for this purpose and a weighing arrangement produced according to the method.
  • a coil e.g. a coil for a transformer
  • individual partial windings must be wound one after the other, which are then subsequently interconnected with one another.
  • a special case is the so-called lintel winding.
  • the production of a coil with such a winding is quite complex.
  • the invention is based on the object of specifying a method by which the manufacture of a coil can be simplified. Another object is to provide an electrical conductor 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.
  • considerable time is saved in the manufacture of the coil.
  • the winding of the coil can be done much faster than before. This applies in particular when a conductor is used, in which additional measures have already been carried out, which were previously carried out during the winding process. This affects e.g. inserting intermediate layers for insulation between windings or edge protection.
  • the process is also suitable for complex nested windings.
  • At least part of the conductor is formed on the winding body to form a disk winding. is wrapped. Particularly high savings in production are possible here, since at least two disc coils are formed during the winding process. If more than 2 conductor pieces overlap in a section of the conductor, several turns can be generated simultaneously with one winding turn.
  • a lintel winding step can follow. It is advantageous if in a further step the ends of overlapping conductor pieces are electrically connected to one another. In this way there is no need to subsequently cut the conductors to length, which also reduces the risk of injury for the winding that is already finished. 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. This means that the conductor is also suitable for applications in the energy sector, e.g. for high voltage transformers.
  • connection points are therefore precisely specified.
  • the conductor pieces can be separated from one another by spacer inserts. As a result, the time-consuming intermediate winding of spacer inserts or edge protection rings, as was previously the case, is eliminated when the transformer is being wound. This applies in particular to the inside of a coil.
  • the third task is solved with a winding arrangement according to claim 10.
  • a winding arrangement is characterized by its small dimensions, since the coil can be wound much more compactly than before. It is also easier and faster to manufacture. Further advantageous embodiments of the invention are specified in the remaining sub-claims.
  • FIG. 2 shows the conductor in cross section along the line II-II
  • FIG. 3 shows another conductor in cross section along the line III-III
  • FIG. 4 shows a partial external view of a winding arrangement.
  • FIG. 1 shows an electrical conductor 1 for a winding arrangement, which consists of a plurality of conductor pieces 3a to 3e.
  • the conductor pieces 3a to 3e are connected to one another at least partially overlapping but isolated from one another, so that a type of pre-assembled conductor is provided.
  • the lengths of the conductor pieces 3a to 3e are predefined 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 dimensioned such that they can be electrically connected to one another after winding. In the present FIG. 1, this is exemplified by the free ends 5c and 5d of the Conductor pieces 3c, 3d shown.
  • the conductor 1 is electrically conductive along the conductor sections B and D.
  • the transitions between the conductor sections A to D are designated by the reference symbols 6a, 6b, 6c.
  • the free ends 5a, 5b of the end-side conductor pieces 3a, 3e form the connections for the external connection of the later winding arrangement. In a section, more than two conductor pieces can also be arranged in parallel.
  • 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 9b.
  • the conductor pieces 3c, 3d are surrounded by a common insulation 7b.
  • the conductor pieces 3c, 3d can comprise one or more conductor wires, for example as a solid conductor or a stranded conductor. This embodiment 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. A capacity-determining intermediate insert 9b is arranged between them.
  • the conductor pieces 3c, 3d are surrounded by the common insulation 7b. In the present embodiment, this can possibly be made thinner than in the embodiment according to FIG. 1.
  • One function of the common insulation 7b is to hold the respective conductor pieces together or to connect them to one another.
  • FIG. 4 shows a partial exterior view of a winding arrangement 12, at. 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, each formed by the conductor pieces 3b to 3d are located 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 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.
  • a conductor according to FIG. 1 is processed on a winding body, for example to form a winding arrangement 12 according to FIG. 4, then significant advantages in production can be achieved. Despite the increased effort in the manufacture of the conductor 1, savings are achieved in the entire winding arrangement 12. This applies in particular to the use with disc coils and with drop windings. Despite large loads think in specialist circles with regard to the handling, it has been shown that the use of the proposed pre-assembled conductor 1 is particularly favorable, particularly in the case of large winding arrangements, for example for high-voltage transformers. Experiments with the method shown have also shown the following advantages:
  • the free ends 5c 5d to be electrically connected to one another are always in the correct position after winding the coil. - Deposits that determine capacity can already be contained in the pre-assembled conductor. There is no need to punch and insert radial inserts when winding a winding arrangement.
  • 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.
