Definitions

  • the invention relates to a method for producing a winding for transformers from square profile wires.
  • the object of the invention is to provide a method of the type mentioned at the outset which, on the one hand, brings about a further improvement in quality and, on the other hand, is more economical.
  • the method according to the invention is characterized in that the profiled wires are brought together and twisted in a twisting head to form a twisted conductor such that the individual profiled wires run obliquely on the two flat sides of the cross-section in the opposite sense and on the narrow sides of the cross-section by an offset pass from one side to the other and the individual profiled wires arranged one above the other in cross-section, possibly at a distance, are arranged side by side, so that this stranded conductor is at least partially surrounded with insulation, that this stranded conductor is connected to a support cylinder which is connected to the core of the Transformer is placed, is wound according to the transformer winding and that the twisting step of the twisted conductor is controlled via the twisting head according to its actual winding diameter.
  • the twisting step of the twisted conductor is controlled via the twisting head in accordance with its actual winding diameter.
  • each individual wire of the wire conductor should go through exactly one cycle per turn.
  • the twisting step can now be controlled with the method according to the invention via the twisting head in such a way that this requirement is taken into account.
  • cooling duct wire In this type of conductor, the partial conductors have a significantly greater offset, so that the two partial conductor stacks are parallel to one another with a space. An intermediate piece is arranged in this space in the area of the crank. This results in a cooling channel for the coolant passage in the radial direction for the wire conductor. If the twisting step according to the invention is now selected as a function of the winding diameter, radial free cooling channels result and the areas of the cranks lie on a radius. The result is non-turbulent cooling flows.
  • the position of the wire conductor on the support cylinder is continuously recorded and this data is fed to a computer.
  • dimensional controls ensure accurate, dimensionally accurate manufacture. It can, for example, vary the insulating paper layers as well as the choice of the insulating paper thickness differences in the dimensions are easily corrected.
  • Drill conductors are subjected to a steady, continuous pressing force, preferably 100-300 N / cm 2, during winding onto the support cylinder. This smoothes the insulating paper accordingly.
  • the paper folds are also virtually ironed out. These folds of paper can occur due to the scaling on the support cylinder side of the paper insulation. By avoiding these folds, a free flow of the cooling medium through the cooling channel is guaranteed.
  • the stranded conductor which has a punctiform epoxy-coated external insulation, is wound onto the carrying cylinder under the action of heat.
  • the epoxy resin-coated paper for the outermost insulating layer which is polymerized, for example, by the action of heat, means that there is no need to add spacer plates which are removed before the winding is installed and which prevent the paper from bulging out during pressing.
  • An essential feature of the invention is the device for carrying out the method according to the invention.
  • This device according to the invention is characterized in that a stranding basket system, on which the individual coils with the profile wires are arranged, is provided, which is followed by a tarpaulin head for torsion-free guidance of the profile wires and that these profile wires running out are guided into a twisting head, in which the uppermost and lowermost conductors are transferred from the two stacked profile conductor stacks to the other stack by cranking, and in that the twisted conductor produced in the drill head passes through an insulator and via a caterpillar take-off of a transversing winding device having the carrying cylinder for the transformer winding is fed.
  • this device With this device according to the invention, it is possible for the first time to produce a complete winding for a transformer at the winding material producer itself.
  • the support cylinder that can be placed on the transformer core for winding the transformer is clamped in the winding device.
  • the winding can be manufactured directly after its manufacture.
  • this winding device is designed in such a way that the wire conductor feed is constant and the carrying cylinder is moved accordingly. Whether the support cylinder is clamped vertically or horizontally remains unaffected.
  • the transversing winding device consists of a spreading dome mounted in a frame, which can be moved horizontally and vertically.
  • the choice of an expanding mandrel has the advantage of universal use for the most varied of winding or support cylinder diameters.
  • the Spreitzdom is pivotable in the horizontal plane.
  • a sloping position of the support cylinders in the horizontal plane ensures an optimal winding process.
  • a sensor that scans the winding diameter is provided on the winding device for controlling the drill head.
  • the drill head can be controlled via its emitting electrical signals, i. H. the optimum twisting step can thus be set automatically.
  • an electronic length measuring device for the continuous monitoring of the position of the conductor on the support cylinder, the Output signals can be fed to a target / actual value comparator, preferably a computer.
  • a target / actual value comparator preferably a computer.
  • pneumatically or hydraulically loadable rollers are provided to generate the pressing force on the stranded conductor during the winding process.
  • rollers serve to smooth the paper insulation.
  • these rollers are heatable or heatable plates are provided for the action of heat on the wire conductor.
  • the punctiform, cast resin-coated paper is polymerized in this way. The paper structures which have reduced the cross section of the cooling channel are thus avoided.
  • a wire conductor machine for producing wire conductors is shown.
  • This twisted pair machine consists of a stranding basket system 1, a planetary head 2, a twisting head 3, an insulator 4, a caterpillar take-off 5 and a transformer winding device 6.
  • the individual coils 7 with the angular profile wires 10 are arranged on the stranding basket system 1.
  • several yoke rings 8, 9 can be arranged one behind the other.
  • Each of the yoke rings can be individually rotated and coupled, so that all of the yoke rings 8, 9 can also be rotated together.
  • Each coil 7 has a brake.
  • the profile wires 10 between the yoke rings must be guided exactly, protected from kinks and twists.
  • each of the coil 7 is running profile wire 10 monitored with the aid of a device, for example a drop bar, which in the event of wire break or wire end z. B. falls by gravity and stops the wire conductor machine.
  • each of the yoke rings 8, 9 is equipped with a disc brake in order to be able to brake the yoke ring 8, 9 in an appropriate time.
  • a disc brake In order to achieve a torsion-free guidance of the profile wires 10, it is necessary to provide a planetary head 2 and back turns between the yoke rings 8, 9 and the yoke ring 8 and the drill head 3.
  • twisting or roving of the individual profile wires 10 takes place in the twisting head 3.
  • the top and bottom conductors are made from two adjacent stacks of the profile wires 10 without damaging the varnish or coating already applied other insulation changed over to the other stack.
  • the twisted conductor 11 now formed in the drill head 3 is wrapped in a variety of layers of insulating paper, glass fiber tapes or foils in the subsequent insulator 4, which may consist of a plurality of coils arranged one behind the other.
  • the insulation can only be applied in certain sections, such as, for example, only at the crimping points, or continuously over the entire wire conductor.
  • a caterpillar take-off 5 is provided for pulling off the twisted pair 11 from the twisted pair machine, which can be pivoted to adapt to the bundle dimension of the twisted pair.
  • the take-up device 6 is connected downstream of the caterpillar take-off 5.
  • This take-up device 6 consists of a transversing spreading dome 12 which can be moved vertically and horizontally in a frame 13. In addition, this Spreitzdom 12 can still be swiveled in the horizontal plane.
  • the winding is now produced directly after the production of the conductor. It is irrelevant whether the transformer winding is manufactured on the support cylinder 14 by means of strips or spacer plates.
  • an encoder 15 is provided which scans the winding diameter. With this transmitter 15, the winding data of the transformer winding, such as the winding diameter, for example, and corresponding signals control the drilling head 3 such that the optimum twisting step is always selected.

Abstract

Les bobines (7) avec les fils profilés angulaires (10) sont disposées sur l'installation de bobinage (1). La transposition des différents fils profilés (10) s'effectue dans la tête de transposition (3). Le conducteur torsadé (11) réalisé dans la tête de transposition (3) est entouré de différentes couches de papier isolant dans le dispositif de guipage (4) aval. Pour le retrait du conducteur torsadé (11) de la machine à réaliser les conducteurs torsadés, il est prévu une chenille de tirage (5) qui pivote pour assurer une adaptation à la dimension de l'assemblage du conducteur torsadé. Le dispositif de bobinage (6) fait suite à la chenille de tirage (5). Ce dispositif de bobinage (6) se compose d'un mandrin extensible traversant (12) se déplaçant dans un bâti (13) dans les sens vertical et horizontal. Ce mandrin extensible (12) pivote également dans le plan horizontal. Sur ce mandrin extensible (12) est disposé un cylindre porteur (14) qui peut ensuite être posé directement sur le noyau du transformateur. Cette installation objet de l'invention permet pour la premièr fois de réaliser un enroulement complet pour un transformateur dans les locaux du producteur de matériau de bobinage. En fonction des calculs et des données de construction, le bobinage peut être réalisé directement après la fabrication du conducteur.
