Abstract: The invention relates to a method for producing windings for a dry-type transformer with in each case one winding for the low voltage (LV winding) and one for the high voltage (HV winding), which are each electrically insulated from one another and whose layers are electrically insulated from one another by virtue of, initially, the winding for the low voltage being produced from electrically conductive wire or tape material and an insulating layer consisting of resin-impregnated fibre material, for example rovings, being wound around said winding, with the winding for the high voltage then being formed on top of said winding, with the individual layers of the winding for the high voltage each being insulated from one another by means of resin-impregnated fibre rovings, wherein, prior to the application of the HV winding, the maximum insulating thickness required for the layer insulation and the number of fibre rovings corresponding to this insulating thickness is determined and, in addition, each winding layer and the associated insulating layer are produced simultaneously with a physical offset with respect to one another and the required insulating thickness is set both via the number of fibre rovings and via the winding feed of the fibre rovings, wherein, in addition, in order to produce the winding, fibre polymer layers formed from fibres and a solid polymer matrix are applied alternately and repeatedly, as layers of insulation, simultaneously with the winding conductor between the individual winding layers of the winding, and, once said fibre/polymer layers have been applied to the individual winding layers, the finished winding is subjected to a curing operation, such that the prepregs applied to the winding are cured.

Abstract: The invention relates to a winding for a transformer or a coil. Said winding is made of a winding material comprising a strip-type electric conductor which is connected in a detachable manner to at least one wide side having at least one layer of insulating material. The winding material is wound about a winding axis in order to prevent axial offset in order to form the threads. The invention further relates to a method for the production of said type of winding.

Abstract: The invention relates to a two-or multiphase transformer having a yoke which has a crosspiece and at least two limbs, over which limbs a coil (17) is placed in each case, and having at least one carrier on which the crosspiece is fixed and which has bearing faces (14) for the coils. At least two supporting blocks (15, 16) for each coil are mounted on each bearing surface (14), said supporting blocks being fitted with elastic compensation elements (35) on the coil-side carrying face (19) and having, on their longitudinal side faces (25, 26) which run perpendicular to the carrying surface (19), at least one strip (27, 28) which extends the creepage path and runs in the longitudinal direction and parallel to the carrying face of the supporting block.

Abstract: The invention is related to a wound transformer core (10, 66, 82) with at least one core loop (12, 14) made of magnetic material, comprising multiple thin amorphous band-like iron sheets (16) which are concentrically stacked around at least one center axis (18, 20). A lower yoke section (24), an upper yoke section (22) and at least two limb sections (26, 28, 30) are developed, comprising a modular plate-like support structure (40, 74, 76) which is glued upright to the center axis (18, 20) on both face sides (70, 72) of the lower yoke section (24) and on both face sides (70, 72) of each limb section (26, 28, 30) in that way, that neighboured iron sheets are glued together at their outer edge. The modular plate-like support structure (40, 74, 76) comprises for each face side (70, 72) of the belonging core sections (24, 26, 28, 30) at least two plate-like modules (42, 44, 46, 48, 50, 86, 88, 90), which are connected each to each other by a first (100) or second (110) plug-in connection..

Abstract: The transformer (11) comprises a core limb (22) to which three windings (32) are arranged next to each other, where the lines of the windings are insulatedly guided against each other, each winding is formed from a core near lower tension winding (34), which is winded by an assigned upper tension winding (36) and the lines of the lower tension winding are axially guided so that the lateral distance between the windings is minimized. The lines of the lower tension windings are guided parallel to the core limbs in the region between the lower- and upper-tension windings. The transformer (11) comprises a core limb (22) to which three windings (32) are arranged next to each other, where the lines of the windings are insulatedly guided against each other, each winding is formed from a core near lower tension winding (34), which is winded by an assigned upper tension winding (36) and the lines of the lower tension winding are axially guided so that the lateral distance between the windings is minimized. The lines of the lower tension windings are guided parallel to the core limbs in the region between the lower- and upper-tension windings. The lines of the lower tension windings are displaced to each other at 120[deg] and are guided to the periphery parallel to the core limbs. The lines of the lower tension windings are guided parallel in one-side manner, to the core limbs. The lines of the nearly arranged lower tension windings are guided to one side and the lines of the other two lower tension windings are guided axially parallel to core limbs to opposite sides. The axial parallely lines guided to the core limbs are equipped with a shrink tube. A shell-like spacer holder is interposed between the lower tension windings and the surrounding upper tension windings, where the radial extent of the spacer corresponds to the thickness of the lines and an annular gap is formed between the lower tension windings and the upper tension windings. An axis-parallel free spacer remains between each of the shell-like spacer holders interposed between lower tension windings and upper tension windings for lines. The shell-like spacer holder interposed between lower tension windings and upper tension windings, has a breadth that extends over a winding area of less than 120[deg] . A channel is proved in the annular gap for flowing with cooling liquid. Three core limbs are provided with three windings formed from lower and upper tension windings arranged next to each other, where the ends on both sides, of the core limbs are connected by a yoke.
