    Multiple parallel ladder with spacer
    The subject invention relates to a multiple parallel conductor with a plurality of twisted, insulated individual conductors, the individual conductors being arranged one above the other in a plurality of partial conductor bundles arranged next to one another. The invention further relates to a method for producing such a multiple parallel conductor and the use of the multiple parallel conductor in a winding of an electrical machine.
    So-called continuous multiple parallel conductors are often used to produce windings for electrical machines, such as transformers. Such multiple parallel conductors consist of a multiplicity of individual, lacquer-insulated individual conductors which are arranged next to one another in a plurality of individual conductor bundles and the individual conductors of individual conductor bundles arranged next to one another are twisted according to a predetermined pattern. Essentially, when twisting at given intervals, the top and bottom individual conductors of a single conductor bundle swap in the opposite direction into the adjacent individual conductor bundle, as a result of which these individual conductors cross over and the number of individual conductors in the various individual conductor bundles remains the same. The multiple parallel conductor is often provided with an external wrapping, for example bundle insulation, for example in the form of a paper wrapping or a lattice band wrapping, for mechanical protection and the stability or for insulation of the multiple parallel conductor. Multiple parallel conductors are manufactured in large lengths and wound on rolls. For processing, these are unwound from the roll and sent to a processing process. A wrap, especially a paper wrap, can also be removed before use. Such multiple parallel conductors are known for example from WO 95/30991 A1 or EP0874373 B1.
    To produce a winding from a multiple parallel conductor, the multiple parallel conductor is arranged in a known manner in a plurality of winding steps in the axial direction next to one another and radially one above the other in order to form the winding of the electrical machine. In the axial direction, spacer plates made of electrically insulating material are often inserted between adjacent parallel parallel conductors in order to form a defined cooling channel in the winding. In a transformer winding, for example, a transformer oil is passed through the cooling channels during operation in order to cool the winding. These spacer plates are inserted by hand between the multiple parallel conductors during the winding process, which is complex and considerably slows down the winding process.
    From WO 94/07251 A1 it is therefore already known to arrange the spacer plates directly on the multiple parallel conductor. A spacer plate / 10 is used at regular intervals in the longitudinal direction of the multiple parallel conductor during the manufacture of the multiple parallel conductor
    AE-4000 AT is arranged on the side of the multiple parallel conductor, which is held on the multiple parallel conductor with a lattice tape. This means that the time-consuming manual insertion of the spacer plates when manufacturing the winding can be eliminated, which significantly reduces the manufacturing time for the winding. However, the use of spacer plates lying loosely on the multiple parallel conductor makes production and processing more difficult because the spacer plates can easily slip. For this reason, WO 94/07251 A1 also suggests using a mesh tape pre-impregnated with partially crosslinked epoxy resin, which hardens after heat treatment and thus ensures the stability required for handling the multiple parallel conductor. This also fixes the spacer plates. The use of such an impregnated mesh tape naturally increases the costs and also increases the manufacturing outlay due to the additional heat treatment. Last but not least, the hardened epoxy resin can also cause problems when winding up the multiple parallel conductor on a roll or when producing the winding of the electrical machine, since the bending of the multiple parallel conductor can be made more difficult by the spacer plates integrated in the resin.
    It is therefore an object of the present invention to provide a multiple parallel conductor with spacer plates, which can be easily manufactured and can be processed safely and easily.
    This object is achieved according to the invention in that a band is applied to a side surface of the multiple parallel conductor in the longitudinal direction of the multiple parallel conductor, spacer plates being arranged on the band in the longitudinal direction and the multiple parallel conductor being wrapped with the band and the spacer plates with a wrapping. The arrangement of the spacer plates on a belt makes the manufacture of the multiple parallel conductor considerably easier, since individual spacer plates no longer have to be processed. In addition, the belt also ensures that the spacer plates on the multiple parallel conductor can no longer move in an uncontrolled manner, which means that a hardening wrap does not necessarily have to be used. On the contrary, the spacer plates on the tape that are loosely attached to the multiple parallel conductor can adapt to the curvature of the winding during the winding process, so that the spacer plates automatically remain essentially radially aligned.
    Further features and advantages of the multiple parallel conductor according to the invention result from the following description of advantageous configurations.
    The present invention is explained in more detail below with reference to FIGS. 1 to 4, which show exemplary, schematic and non-limiting advantageous embodiments of the invention. / IO shows 2

    Fig. 2 and 3 versions of a tape with spacer and
    4 shows a further view of a multiple parallel conductor according to the invention with spacer plates and external band.
    1 shows an exemplary embodiment of a multiple parallel conductor 1 according to the invention, which consists of several, here two, individual conductor bundles 2 arranged next to one another. A plurality of isolated, preferably enamel-isolated, individual conductors 3 are arranged one above the other in each individual conductor bundle 2. The individual conductors 3 or the individual conductor bundles 2 extend in the longitudinal direction x over the length of the multiple parallel conductor 1. An individual conductor 3 usually has a rectangular cross section, the individual conductors 3 lying against one another in a single conductor bundle 2 on the long sides of the rectangular cross section.
    However, it should be mentioned that a single conductor 3 itself can again consist of several insulated partial conductors, which can be arranged next to one another, one above the other or also in a matrix in a single conductor 3. A multiple parallel conductor with such individual conductors 3 consisting of partial conductors is described, for example, in WO 12/113851 A1 or WO 12/113853 A1. Such individual conductors 3 consisting of several partial conductors are expressly understood as individual conductors 3 in the sense of the invention.
    The uppermost and lowermost individual conductors 3 of adjacent individual conductor bundles 2 change at twists 4 provided at regular intervals along the longitudinal direction x of the multiple parallel conductor 1 into the respective adjacent individual conductor bundle 2, the change taking place in different directions, for example from top left to right and bottom from right to left so that the number of individual conductors 3 in the individual conductor bundle 2 remains the same. This process is well known and is referred to in connection with multiple parallel conductors 1 as twisting, or as a result as multiple parallel conductors 1 with twisted individual conductors 3.
    For orientation purposes only, the sides with the twisting points 4 are referred to as the top and bottom of the multiple parallel conductor 1 and the sides of the multiple parallel conductor 1, which connect the top and bottom, as side surfaces 5. The side surfaces 5 are usually defined by the narrow sides of the rectangular cross sections of the individual conductors 3 formed and the top and bottom by the long sides of the rectangular cross sections of the individual conductors 3. The designation top, bottom and side surface has nothing to do with a specific orientation or position of the multiple parallel conductor 1 and is not to be understood as such.
    Spacer plates 6 are now arranged on at least one side surface 5 of the multiple parallel conductor 1 along the longitudinal direction x of the multiple parallel conductor 1 at predetermined intervals (see also FIG. 4). The spacer plates 6 are on a flat belt 7 / IO 3 '
    AE-4000 AT attached and are arranged with the tape 7 during the manufacture of the multiple parallel conductor 1 on the multiple parallel conductor 1. Such a band 7 is shown in FIG. 2 with the spacer plates 6 arranged thereon. The band 7 can be made of any, preferably electrically non-conductive material, such as plastic or paper. The band 7 is preferably flexible. The spacer plates 6 are made of an electrically non-conductive material, for example pressboard. How the spacer plates 6 are attached to the belt 7 is of no importance for the invention and any suitable method can be used. For example, the spacer plates 6 could be glued to the tape 7.
    Likewise, it does not matter whether the band 7 lies directly on the multiple parallel conductor 1 (as in FIG. 1) or whether the spacer plates 6 lie directly on the multiple parallel conductor 1 and the band 7 is arranged on the outside (as in FIG. 4).
    In a further possible embodiment, the band 7 consists of at least two sub-bands 7 ', 7' ', between which the spacer plates 6 are arranged, with at least one sub-band 7', 7 '' being arranged on each side of the spacer plates 6 (FIG. 3 ). The mutually facing sides of the sub-bands 7 ″, 7 ″ ″ could be designed to be adhesive, for example in the form of a paper adhesive tape, so that the two sub-bands 7 ″, 7 ″ ″ are pressed together to form the band 7 and at the same time the spacer plates 6 are fastened in between. However, the facing sides of the sub-bands 7 ″, 7 ″ ″ do not necessarily have to be self-adhesive, but the spacer plates 6 can again be attached anywhere between the sub-bands 7 ″, 7 ″ ″, for example again using an adhesive. It is not even necessary for the sub-bands 7 ″, 7 ″ ″ to be adjacent.
    After the tape 7 has been arranged on the multiple parallel conductor 1, the multiple parallel conductor 1 is provided in the usual manner with a wrapping 8, usually a grid tape or a paper wrapping. Although, when using a mesh tape as the wrap 8, as indicated in FIG. 1, a mesh tape impregnated with epoxy resin which is cured can also be used in a known manner, preferably no such mesh tape impregnated with epoxy resin is used for the wrap 8.
    The height H D of the spacer 6 preferably corresponds to the height H L of the multiple parallel conductor 1, that is to say the height of the side faces 5. After the individual winding turns in a winding of an electrical machine are pressed together in the axial direction of the winding, the adjacent multiple parallel conductors 1 of the winding turns are supported on the spacer 6. If the height H D of the spacer plates 6 were less than the height H l of the multiple parallel conductor 1, this could lead to a displacement of individual conductors 3 in the winding, which could impair or even destroy the function of the winding.
    / 10
    AE-4000 AT
    For the same reason, the distance between two spacer plates 6 on the multiple parallel conductor 1 in the longitudinal direction x is preferably planned such that there is always an overlap of the spacer plates 6 lying next to one another in the axial direction in the resulting winding. In this way it can be ensured that the individual winding turns are supported on the spacer plates 6 in the event of an axial tensioning of the winding. After the diameter of the winding turns is known in advance, the arrangement of the spacer plates 6 can easily be planned in advance.
    The width B of the band 7 is preferably chosen to be smaller than the height H L of the multiple parallel conductor 1, but could also be selected with the height H L of the multiple parallel conductor 110.
    To produce the multiple parallel conductor 1, the multiple parallel conductor 1 is first produced in a known manner by twisting the individual conductors 3. The band 7 with the spacer plates 6 is then applied to the side of the twisted multiple parallel conductor 1 and the wrapping 8 is then attached. Thereafter, the multiple parallel conductor 1 can be wound on a drum and shipped or shipped for further processing.
