Definitions

  • the invention relates to a winding arrangement with a number of axially spaced apart and electrically connected to one another forming a series circuit, each having a conductor that is wound from an inner end to an outer end of the respective winding portion and thereby the winding portion enlarged in the radial direction, at least one winding section being electrically connected at its outer end to the inner end of the winding section following in the axial direction.
  • the invention also relates to a transformer and a coil or choke with such a winding arrangement.
  • the above-mentioned winding arrangement is for example from EP 2 251 877 B1 known.
  • the winding arrangement shown there consists of a series connection of so-called disc windings, which are arranged at a distance from one another. The outer end of each disc winding is connected to the inner end of the disc winding arranged adjacent in the axial direction. In this way, during the production of the overall winding, the conductor can always be wound onto a shaping winding from the inside to the outside for each disc winding. This simplifies the manufacture of the winding arrangement with a consequent cost saving.
  • the intermediate section of the conductor which extends between the disk windings, not only has to bridge the axial distance between the adjacent disk windings but also the radial expansion of the winding.
  • the adjacent disc windings must therefore be arranged at a large distance from one another in order to create space for said intermediate section.
  • a winding arrangement is known in the manufacture of which a pre-assembled conductor is used.
  • the conductor used consists of conductor pieces which are arranged in pairs and have free conductor ends.
  • the pre-assembled conductor is formed into a winding arrangement with the help of a lintel winding.
  • the EP 2 052 393 A2 shows a winding arrangement consisting of disc windings arranged in different winding layers.
  • the winding layers are spaced apart from one another in the radial direction by cooling channels.
  • the disc windings form what is known as a lintel winding, a first disc winding being wound from the inside outwards and the disc winding following in the axial direction from the outside inwards.
  • the object of the invention is to provide a winding arrangement of the type mentioned at the beginning, which can be produced cost-effectively and whose winding sections are arranged at a comparatively small distance from one another.
  • the invention solves this problem in that at least one subsequent winding section in the axial direction forms a step area in which its inner end in the radial direction is level with the outer end of the winding section is arranged, with which this is electrically connected.
  • a winding arrangement in which the connection of the one winding section to the respectively adjacent winding section is achieved by simply crimping the conductor without the conductor having to be guided over long distances between adjacent winding sections. All winding sections have the same winding direction. The winding direction does not change within the scope of the invention.
  • the entire winding arrangement preferably consists of a single wound conductor. This continuous conductor is wound in such a way that winding sections are formed which are arranged one after the other in the axial direction. The spiral winding of the conductor at certain intervals creates winding sections. In the winding sections, the conductor tracks isolated from one another lie against one another and, with increasing number of turns, enlarge the winding section in a direction which is referred to here as the radial direction.
  • winding interior formed closed winding sections which delimit a section interior.
  • the section interiors of the winding sections are at least partially aligned in the axial direction, so that the stack of winding sections defines an inner contour, which is referred to below as the winding interior.
  • each winding section forms an eccentric step area in which its inner winding layer is at a greater distance from an imaginary central axis of the winding interior than outside the step area.
  • This greater distance than the other sections corresponds to the distance between the inner and the outer end of the adjacent winding section, in other words corresponds to the thickness of the winding.
  • the outer conductor therefore only has to be guided laterally, that is to say in the axial direction, from the outer winding layer of the respective winding section to the inner winding layer of the adjacent winding section.
  • the conductor cranked in this way in said step area then serves as the inner winding layer of said adjacent winding section.
  • each winding section advantageously forms a step area.
  • the first winding section forms the so-called beginning of the winding arrangement, via which the winding arrangement is connected, for example, to the phase connection of a transformer or a choke.
  • the outer end of the first winding section is then in the step area with the inner one Connected to the end of the subsequent winding section in the axial direction, so that this is then the first winding section which has a step area. This applies accordingly to the winding sections that follow in the axial direction.
  • each winding section is a disk winding configured in the form of a disk.
  • the individual winding layers are wound exactly one above the other, so that they extend in the form of a disc, as it were, in a common layer or "plane". According to this advantageous further development, the winding arrangement is made even more compact.
  • Each disc winding is advantageously designed to be circumferentially closed and delimits a section interior.
  • the section interiors of the disc windings overlap in the stack that results from the stringing together of the disc windings in the axial direction, so that space is provided for a leg of a transformer or reactor core.
  • each disc winding forms a circular ring section outside the step area. This makes it possible to use a circular cylindrical shaped body in the production of the winding arrangement according to the invention, on which the winding sections can be wound. This reduces the manufacturing cost.
  • the disc windings arranged next to one another in the axial direction delimit a circular cylindrical interior which has a central axis, the first winding layer of each disc windings being at a greater distance from the central axis in the step area than in the ring area.
  • the circular cylindrical interior of a winding allows the inclusion of the usual Leg of a yoke, so that it does not have to be laboriously adjusted.
  • the center of the step area of each disc winding expediently spans an angle ⁇ with the center of the step area of the directly adjacent disc winding with respect to the center axis. This rotation of the step areas around the center axis is necessary in order to bring the outer winding layer of the disc windings to the radial level or the radial height of the first winding layer of the respective subsequent disc winding.
  • each disc winding is arranged in alignment with the next but one disc winding.
  • the entire winding arrangement forms eccentric bulges only at two points. This also simplifies the adjustment of the winding arrangement and its subsequent handling.
  • the angle ⁇ is advantageously 180 degrees.
  • the bulges lie opposite one another on different sides of the winding arrangement. Deviating from this, the angle ⁇ is in the range from 10 to 30 degrees.
  • both bulges are arranged on the same side of the winding arrangement, for example at the front. In this way, it is possible to limit a conductor space that is used to accommodate inlet and outlet lines.
  • any type of conductor can be used within the scope of the invention.
  • the conductor is a drawn wire conductor or a flat foil conductor.
  • the conductor is advantageously a strip conductor configured in the form of a strip. Copper or preferably aluminum, for example, come into consideration as the strip conductor material, the conductor or, here, the strip-shaped strip conductor being surrounded at least in sections by an insulating layer.
  • the insulating layer can be, for example, an insulating lacquer layer or an insulating film. During winding, the insulating film is placed between successive winding layers.
  • the strip conductor is bent over twice in the step area.
  • the strip conductor can be guided particularly easily in the axial direction from the one winding section in each case to the subsequent winding section.
  • the winding arrangement is advantageously part of a transformer or a coil or choke.
  • FIG. 1 shows a winding arrangement 1 according to the prior art.
  • the winding arrangement 1 shows a winding of a conductor 2 which is electrically insulated from the next layer, for example by interposing an insulating film or by an insulating varnish.
  • Said conductor 2 is wound so that the layers of the conductor 2 lie one above the other in a spiral shape.
  • These conductor tracks lying spirally one above the other are referred to here as winding layers.
  • the first winding layer therefore delimits an interior of the winding, which is referred to here as the section interior 11.
  • the winding layers lying on top of each other lie on top of each other in a layer.
  • the winding layers form disc-shaped disc windings 3a, 3b, 3c ... 3n as a winding section.
  • the winding sections are arranged one behind the other in the axial direction 4.
  • the disc windings 3a, 3b, 3c ... 3n are all arranged at a distance D from one another, wherein the distance D can be different.
  • the distance between the disc windings 3a and 3b is, for example, smaller than the distance between the disc windings 3b and 3c.
  • Each of said disc windings 3a, 3b, 3c ... 3n has an inner end 5a, 5b, 5c or 5n and an outer end 6a, 6b, 6c or 6n.
  • each disc winding 3a, 3b, 3c ... 3n is wound from the inside out, as indicated for each disc winding 3a, 3b, 3c ...
  • Figure 2 shows an exemplary embodiment of the winding arrangement 8 according to the invention, which forms an electrical series connection of winding sections, here disk windings 3a, 3b, 3c ... 3n, corresponding to the winding arrangement 1 according to FIG.
  • all disc windings 3a, 3b, 3c ... 3n have the same winding direction 7, i.e. are from the inner end 5a, 5b, 5c ... 5n to the respective outer end 6a, 6b, 6c ... 6n of each disc winding 3a , 3b, 3c ... 3n wound.
  • 3n-1 is connected to the inner end of a further disc winding 3b, 3c, 3d which follows directly or immediately in the axial direction, with the exception of the last partial winding 3n of the series connection.
  • this is connected with its outer end 6n to a high-voltage connection, not shown in the figures, of the said transformer.
  • the inner end 5a of the first disc winding 3a is connected to a further high-voltage connection of the said transformer.
  • the disc winding 3b is raised so far with respect to the disc winding 3a in the radial direction 9 in the area of the connection from 6a to 5b that its inner end 5b is at the same "radial" height as the outer end 6a of the disc winding 3a .
  • the conductor 2 therefore only has to be bent or cranked out of the "layer" of the disc winding 3a in the axial direction 4 in order to form the layer of the adjacent disc winding 3b to be transferred. There this forms the first winding layer.
  • the further winding layers can be wound in the same direction by simply winding them further. A long conductor connection between the winding sections 3a, 3b, 3c ... 3n as in Figure 1 is therefore avoided within the scope of the invention.
  • the winding direction 7 is the same for all disc windings 3a, 3b, 3c ... 3n.
  • the disc windings 3a, 3b, 3c ... 3n can be arranged with a small distance D from one another, the manufacture of the winding arrangement 8 remaining inexpensive.
  • Figure 3 shows the winding arrangement 8 according to FIG Figure 2 in a perspective view. It can be seen that the disc windings 3a, 3b, 3c are arranged one behind the other in the axial direction 4 at a small distance from one another. In the in Figure 3 In the illustration shown, the disc winding 3a faces the viewer. It can be seen that each disc winding 3a, 3b, 3c ... 3n is designed to be circumferentially closed and a section interior 13 is thus delimited.

  • the interior 14 is used to accommodate a magnetizable material which is set up to guide a magnetic field with low magnetic resistance.
  • the individual disc windings 3a, 3b, 3c ... 3n are not circular in a plan view and therefore do not individually delimit a circular section interior 13. Rather, each disc winding 3a, 3b, 3c ... 3n has an eccentric step area 10a, 10b, 10c. ..10n, which has a greater distance from an imaginary central axis of the circular cylindrical interior 14 of the winding arrangement 8 than the remaining section of each disc winding 3a, 3b, 3c ... 3n, which follows a circular shape in a plan view.
  • step area 10a is not arranged in alignment with the step area 10b of the disc winding 3b, which immediately follows the first disc winding 3a in the axial direction. Rather, the step area 10b is circumferentially offset with respect to the step area 10a, so that the two center points of the step areas 10a and 10b split an angle ⁇ with one another with respect to the imaginary center axis of the interior 14 of the winding arrangement 8. It can also be seen that the step area 10c of the next but one disc winding 3c is arranged in alignment with the step area 10a of the first disc winding 3a. This applies accordingly to the level ranges 10b and 10d. Each disc winding 3a, 3b, 3c ...
  • 3n is therefore arranged with its step area 10a, 10b, 10c ... 10n in alignment with the next but one disc winding 3a, 3b, 3c ... 3n, the step areas 10a, 10b, 10c. ..10n of disc windings 3a, 3b, 3c ... 3n, which follow one another directly, are twisted against one another. Therefore, a total of two eccentric bulges 15, 16 can be seen in the winding arrangement 8, which are formed by the step areas 10a, 10c, 10e ... 10n-1 or the step areas 10b, 10d, 10f ... 10n. If the disc windings 3a, 3b, 3c ...
  • 3n are numbered with whole numbers beginning with 1, one bulge 15 is separated from the disc windings 3a, 3c, 3e ... 3n-1 with an even number and the other bulge 16 from the disc windings 3b , 3d, 3f ... 3n formed with odd numbers.
  • the conductor 2 in the outer winding layer in the step region 10b is axially offset out of the plane of the disc winding 10a, that is, it is cranked and thus forms the inner end 5b of the second disc winding 3b.

  • Figure 6 shows the winding arrangement according to FIG Figure 5 in the manufacturing process. It can be seen here how the strip conductor 2 is bent over during manufacture.
  • the one in the Figures 5 and 6th The illustrated conductor 2 is designed to be flexible so that it can be bent twice in the step area 10. At a first bending point 17, it is bent backwards against the winding direction 7. At a second bending point 18, the strip conductor 2 is bent over again so that it extends again in the desired winding direction 7. With this one When bent twice, the conductor 2 is offset in the axial direction so that it can form the first winding layer of the subsequent disc winding.
