Embodiment Construction

[0023] figure 1 A perspective view showing winding 1. exist figure 1 In the example shown, electrical conductors 3 a , 3 b , 3 c , 3 d (not shown) and at least partially electrically insulating layers 4 a , 4 b , 4 c are arranged on carrier 2 . The carrier 2 has a curved shape which corresponds to the radius of the winding 1 . exist figure 1 In the example shown, the electrically insulating layers 4a, 4b, 4c are secured by a casing 5 of cast resin. This makes it possible to arrange the respective electrical conductors 3 a , 3 b , 3 c , 3 d on the carrier 2 and to have the respective potting resin jacket 5 completely surround the carrier 2 during subsequent processing. Based on the electrical insulation properties of the casting resin jacket 5, the casting resin jacket fulfills the function of the electrical insulating layers 4a, 4b, 4c.

Abstract

The invention relates to a winding comprising a wound electrical conductor, wherein the electrical conductor has an electrically insulating layer. Furthermore, the invention relates to a method for producing a winding. By using a carrier, on which the electrical conductors can be arranged and electrically insulated, a one-piece production of the winding can be achieved. The carrier is designed as a helix, in particular in the form of a cylindrical helix, and thus precisely enables a practically unlimited one-piece production of the winding. At the same time, the cross-section and / or the width of the electrical conductor can be varied depending on the position on the carrier.

Description

technical field [0001] The invention relates to a winding comprising a wound electrical conductor, wherein the electrical conductor has an electrical insulation layer. Furthermore, the invention relates to a winding production method. Background technique [0002] Manufacture of power transformers as cast resin transformers or as distribution transformers for high-voltage power grids is a very labor-intensive and cost-intensive process. Coil windings, in particular for low-voltage and high-voltage windings, can currently only be produced using multiple and expensive work steps. For this purpose, the winding wire is wound into component windings on a winding machine to achieve the necessary winding diameter. The partial windings produced in this way are then connected to one another by means of corresponding connecting elements to form low-voltage or high-voltage windings, as described, for example, in DE 198 09 572 C2. [0003] DE2609548C2 also introduces a winding device...
