Definitions
- the invention relates to a winding with a wound electrical conductor, wherein the electrical conductor has an electrical insulation. Furthermore, the invention relates to a method for producing a winding.
- a power transformer as a cast-resin transformer or as a distribution transformer for high-voltage networks is a very labor-intensive and cost-intensive process.
- the winding of the coils for the low and high voltage winding is currently possible only in several and complex steps.
- partial windings of a wound wire are wound on a winding machine in such a way that the necessary wicxing diameter is achieved.
- the partial windings thus produced are connected to each other by means of appropriate connecting elements as an upper or lower voltage winding, as described for example in DE 198 09 572 C2.
- DE 260 95 48 C2 also describes a winding arrangement for power transformers with iron core and coils, wherein the conductor dimension corresponds in the axial direction of the coil height and all turns of each coil are connected in series, wherein the number of turns per coil from the center to the end of the Remove winding.
- DE 32 14 171 A1 describes a high-voltage transformer with a choke coil, wherein a disk coil contains a plurality of turns, in each of which connected in series sub-conductors lie on one and the same radial plane to the core leg.
- DE 15 39 623 describes a device for generating homogeneous magnetic fields with very high field strength. The stray flux in the outer space of the device for generating homogeneous magnetic fields by two groups arranged parallel to each other by currents of opposite direction through conductors, so that the external magnetic field is practically reduced.
- DE 245 748 A1 describes a winding with high current arresters.
- the object of the present invention is to provide a winding and a method for producing a winding, which ensures the production of a one-piece coil.
- At least two electrical conductors are arranged on a carrier, wherein the electrical conductors are insulated from each other and the carrier has a curved shape.
- the carrier is deformed as a conduction band by deformation by means of a device in such a way that the radius to the finished winding is ensured by the thus deformed carrier band.
- the carrier in the form of a cylindrical spiral configured as a helix or helix and thus a one-piece production of the electrical conductor is ensured.
- the helical shape as a carrier is ensured that the corresponding coil can be practically produced in a continuous process, so that only the different radii of the windings and / or the axial Er extension is the only mimicking factor in the production of the winding.
- a carrier element is turned off as einschlagige disc, the carrier element can be combined by means of Aussparungs- and / or connecting elements with other Tra ⁇ gerierin to a carrier. Due to the modular design of the Tragers possible consisting of Trager ⁇ elements can be formed within the manufacturing process quickly and easily a carrier.
- the carrier can be divided by a laser treatment in electrically conductive zones as an electrical conductor and in electrically insulating zones as insulation.
- the carrier can be divided by means of a galvanic treatment into electrically conductive zones as an electrical conductor and into electrically insulating zones as an insulation.
- the carrier for introducing electrically conductive materials in particular carbon nanotubes, recesses are provided, wherein the electrically conductive materials define the electrical conductor.
- the introduction of electrically conductive materials in recesses previously defined in the carrier makes it possible to quickly and easily define and produce electrical conductor paths.
- an insulating film is to be introduced between individual segments of the carrier during the manufacturing process.
- the width and / or the cross section of the electrical conductors on the carrier vary depending on the location.
- electrical stresses in particular voltage overloads
- the structural measures By varying the width and / or the cross section of the electrical conductor, electrical stresses, in particular voltage overloads, can be compensated by the structural measures. It is also possible due to the evolution of heat within the winding and / or the carrier, the number and / or dimensions of the conductors in certain segments of the winding to change so that a nearly equal thermal load is ensured in the winding.
- this form of technical production is not possible.
- the electrical conductors are arranged parallel to one another on the carrier.
- the carrier can consist of an electrically insulating material.
- a method for producing a winding, wherein between at least two electrical conductors are arranged on a carrier, wherein the electrical conductors are insulated from each other and the carrier is bent into a curved shape.
- the carrier is designed in the form of a cylindrical spiral, wherein the radius of this helical shape thus formed corresponds to the radius of the winding.
- Fig. 1 is a perspective view of the winding
- Figure 2 shows a plan view of the transformer with four electrical conductors ⁇ rule.
- 3 shows a plan view of a carrier consisting of two carrier elements;
- Fig. 4 is a perspective view of a carrier in helical form
- FIG. 1 shows a perspective view of the winding 1.
- an electrical conductor 3a, 3b, 3c, 3d (not shown) and an at least partially electrical insulation 4a, 4b, 4c are applied to a support 2 .
- the carrier 2 has a curved shape which corresponds to the radius of the winding 1.
- the electrical insulation 4a, 4b, 4c is ensured in the example shown in FIG. 1 by a casting resin sheath 5.
- corresponding electrical conductors 3a, 3b, 3c, 3d are arranged on the carrier 2 and in a subsequent manufacturing process a corresponding GiefSharzumman- tion 5 completely surrounds the carrier 2. Due to the electrical insulation properties of the casting resin sheath 5, the casting resin sheath thus fulfills the function of the electrical insulation 4a, 4b, 4c.
- FIG. 2 shows a plan view of the carrier 2 with four electrical conductors 3a, 3b, 3c, 3d. Between the respective electrical conductors 3a, 3b, 3c, 3d, an electrical insulation 4a, 4b, 4c is arranged on the carrier 2. There is either the possibility that the electrical conductor 3a, 3b, 3c, 3d is applied to the support 2 consisting of an insulating material. In this case, the cavities between the conductors 3a, 3b, 3c, 3d are automatically electrically insulated and have corresponding isolation regions 4a, 4b, 4c.
- the carrier 2 consists of an electrically conductive material and by specific working processes regions between the individual conductors 3a, 3b, 3c, 3d are changed so that they have an electrical insulation property and thus represent an electrical insulation 4a, 4b, 4c.
- FIG. 1 A plan view of a carrier 2 consisting of two carrier elements 6a, 6b is shown in FIG.
- the carrier 2 has two electrical conductors 3a, 3b, which are arranged parallel to each other. Between the electrical conductors 3a, 3b, an electrical insulation 4a is arranged.
- the carrier 2 consists of two carrier elements 6a, 6b, which can be combined by means of corresponding connecting elements 7a, 7b to form a carrier.
- the connecting elements 7a, 7b has, in particular, such forms, which ensure a simple, firm and permanent connection. In particular, mating shapes, such as dovetail joints, are included. Conventional joining techniques, such as screwing or welding, are made possible by means of the aforementioned connecting elements 7a, 7b.
- FIG. 4 A perspective view of a carrier 2 in helical form is shown in FIG. 4.
- a practically infinitely long coil can be designed. This results in the possibility of being able to produce a winding 1 independently of corresponding partial windings, which considerably speeds up the manufacturing process and makes it more cost-effective.
- a winding 1 can be produced as a continuous, one-piece coil. This eliminates the production of individual coils or partial windings, which must be connected only very cumbersome to a winding 1. The necessary electrical connections affect the performance of the corresponding winding 1 negative.
- radial Kuhlungskanale omitted, which ensures a relatively smaller winding 1 compared to conventional windings.
- the possible stress stress between the individual winding segments can be calculated and completely avoided at the points of higher stress loads by means of corresponding winding-technical measures.
- the leadership of the electrical conductor 3a, 3b, 3c, 3d on the support and width and / or the cross section of the electrical Leitex 3a, 3b, 3c, 3d can thus be selectively changed and thus the voltage stress manufacturing technology minimized. This results in the possibility of making test windings 1 that are stronger in terms of test stress compared to previously known windings.
