Definitions
- the invention relates to a method for producing a coil winding consisting of one or more winding layers of substantially rectangular-shaped conductors or conductor bundles and a winding device for producing a coil winding consisting of one or more winding layers of substantially rectangular-shaped conductors or conductor bundles.
- FIG. 1 The basic structure of winding layers arranged concentrically in one another and electrically connected in parallel is known from the prior art, for example European Patent EP 0 092 018 B1.
- Figures 1 and 2 show the basic kon ⁇ constructive structure of such winding layers 1 and thus constructed coil windings.
- the winding layers 1, which are arranged concentrically with one another about a common coil center axis 7 and which are made of substantially rectangularly shaped conductors or conductor bundles 6, are held together by holding elements 2 at the coil ends, for example so-called winding stars made of metal or plastic.
- the retaining elements 2 arranged in the two distal end sections of the coil are held together by a tensioning construction, for example by a plurality of tension elements 3 made of impregnated glass fibers, which are attached along the winding. Between the holding elements 2 and the coil or winding ends are usually especially when the Halteele ⁇ elements 2 are electrically conductive, insulating elements 4 attached.
- the concentrically nested winding layers 1 are in the radial direction preferably by further Isolations ⁇ elements 5, for example, electrically insulating gap strips, distanced to produce vertical gaps for the natural air cooling of the entire reactor winding.
- the number of turns of the winding layers 1 and the electrical coils to be manufactured are determined in such a way that both the desired inductance is achieved and the desired current and operating temperature distribution via the parallel-connected winding layers 1 - see FIG , This requirement results in different numbers of turns decreasing predominantly from the inside to the outside for the winding layers 1 connected in parallel.
- the most uniform possible axial voltage gradient in all winding layers 1 and thus the avoidance of significant voltage differences between the opposite windings of adjacent winding layers 1 is ensured by achieving equal heights or equal axial lengths of the individual winding layers 1, ie by maintaining the same winding layer heights H possible. This is achieved by adapting the height GH1, GH2, GH3 of the conductor or conductor bundle 6 measured in the axial direction of the winding layers 1 to the different numbers of turns of the winding layers 1 connected in parallel.
- the height GH1, GH2, GH3 of the conductor or conductor bundle 6 in the individual winding layers 1 measured in the axial direction of the winding layers 1 is also referred to as a pitch which defines the dimension of the conductor or conductor bundle 6 in the direction of the winding or coil axis. Due to the number of turns predominantly decreasing from the inner winding layers 1 to the outer winding layers 1, the conductors or conductor bundles 6 have larger dimensions in the outer winding layers 1 in the axial direction.
- the conductors or conductor bundles 6 of the outer winding layers 1 in a direction parallel to the Spulenl Kunststoffs- or Spulenstoffachse 7 greater heights GH 2, GH3, as the heights GHL the conductor or conductor bundle 6 of the inner winding layer 1 of the coil.
- the adaptation of the axial height GH1, GH2 or GH3 of the conductor or of the conductor bundle 6 to the respectively required conductor or conductor bundle 6 with approximately or substantially rectangular cross-sectional shape is achieved by pressing a round conductor or a cable-shaped conductor material.
- the required dimensions of the conductors or conductor bundles 6, in particular the aforementioned pitches GH1, GH2, GH3, are calculated.
- the increase due to the electrical external insulation of the conductor or conductor bundle 6 to be applied in the following is taken into account when determining the required dimensions.
- the original conductors to be processed or the conductor bundle strands are formed or pressed onto a substantially rectangular cross-sectional shape with the dimensions calculated in advance.
- the pressing of the conductor or the conductor bundle is a separate process in the known processes, which is upstream of the actual winding process.
- the round conductor or the pre-produced conductor bundle runs through several pairs of pinch rollers made of hardened steel.
- the application of the outer insulation for the conductor or the conductor bundle is integrated into this process. In this case, high-temperature-resistant insulation films and / or impregnable fabric tapes are used.
- the application of the insulating material takes place immediately after the deformation of the conductor or of the conductor bundle, but in any case before winding up the preformed conductor or the conductor bundle on a winding material supply drum, where the conductor or the conductor bundle is intermediately stored, before that - in a later process - electric coils are wound.
- the processes of pressing the conductor or conductor bundle and applying the external insulation also have manufacturing tolerances that result in a deviation between the actual and the pre-calculated dimensions of the cross-sectional shape. Since the conductors or the conductor bundles have been wound onto a wrapping material storage drum again after pressing, slight cross-sectional deformations or cross-sectional changes can also occur due to forces that occur in the conductor or conductor bundle during winding. Finally, for the same reason, the cross-sectional dimensions of the conductor or of the conductor bundle 6 may also change during the actual winding process, ie during the winding of the winding layers 1.
- the contact pressure is understood as meaning the surface load with which the individual turns of a winding layer 1 are pressed against one another in the direction of the central axis 7 of the coil during the winding process by means of a pressing device or with manual pressing tools. If, for example, the conductor or the conductor bundle 6 has too great an axial height GH1, GH2, GH3, the contact pressure is increased. If the axial height GH1, GH2, GH3 is undersized, the contact pressure is reduced, i. it is wrapped "looser".
- settling in the affected winding layers 1 may occur due to the thermal stress on the winding layers 1 or the single-layer or multi-layer winding. These are in particular shortenings of the winding layer height H of those winding layers 1 which have been wound with reduced contact pressure.
- the present invention seeks to propose a method and a winding device, can be made more efficient than previously with the coils of the type mentioned, the winding layers are also neither too large contact pressure nor too loose wound.
- This object is achieved according to the invention in that the deformation of the conductors or bundles of conductors with a deformation device into the essentially rectangular cross section, the insulation of the deformed conductors or conductor bundles and the winding of the conductors or conductor bundles to the desired winding position are carried out in a single operation is that an axial length of an already gewekelfelten part of the winding layer is compared as an actual value with a target value for the already wound part continuously or periodically, that a target pitch for the still wound part of the winding layer is determined and that the deformation device der ⁇ art is adjusted so that the final axial length or winding layer height of the winding layer corresponds to a desired value or desired value.
- An advantage resulting from the features of the characterizing clause of claim 1 is that by combining the sub-processes, deforming, insulating and winding the conductors or conductor bundles into a closed integrated process costs and cycle time for the production of electrical windings, especially those for dry-insulated choke coils without iron core can be reduced.
- a further advantage with regard to increasing the quality of the product resulting from the method according to the invention is that at least one of the continuous control or regulation of the dimensions of the conductor or conductor bundle during the laying of the turns during the winding process largely constant contact pressure can be used.
- the risk of Wicklungs für selspule can be eliminated by the thermal stress in the subsequent operation of the Dros ⁇ selspule.
- the risk of damage or destruction of the outer insulation for the conductor or the bundle of conductors which has hitherto been present can be minimized or prevented as a result of excessive contact pressure.
- a winding layer has at least two winding sections with different pitches. As a result, it is possible, for example, to realize winding layers in which differently stressed parts of the winding are provided with a different insulation or a different insulation thickness.
- a winding device which is characterized in that it comprises at least one deformation device, at least one device for isolating and at least one automatic or manually operated regulating device which adjusts or deforms the deformation device via which the deformation device is adjustable such that the final axial length or winding layer height of the winding layer corresponds to a predetermined value or nominal value.
- the regulating device is designed for the automated or user-assisted change of the adjustment values of the deformation device during a running winding process.
- continuous intervention or continuous or quasi-continuous regulation of the deformation values is possible, so that the desired values of the final winding position are best possible can be achieved.
- a production with short cycle times is possible.
- control device provision is made for the control device to be designed for the automated or user-assisted change of the adjustment values of the device during an ongoing winding process. This also makes it possible to achieve the dimensional setpoint values of the winding layer to be produced sufficiently accurately, in particular if the regulating interventions take place prematurely or continuously or periodically. Likewise, too great variations in the shaping of the conductor or conductor bundles can thereby be avoided.
- FIG. 1 shows a detail of a coil of three coaxially arranged, cylindrical winding layers according to the prior art in a simplified, schematic illustration
- FIG. 2 shows a detailed detail from FIG. 1 on an enlarged scale
- FIG. 3 shows a schematic illustration of an embodiment of the method according to the invention for producing winding layers of a coil winding
- Fig. 4 is a highly schematic view of a winding device for carrying out the inventive method.
- FIG. 3 shows schematically an embodiment of the method according to the invention.
- the process of the production of the coil or the processing of the conductor or conductor bundle 6 is framed in the figure by a broken line and denoted by 13. It comprises the steps of the deformation 12 of the conductor or conductor bundle 6, the insulation 14 and the winding 15 for the required winding layer 1 or coil winding.
- the axial length or height of the wound winding layer 1 or coil is measured continuously or periodically by a measuring element 17, wherein at the same time the number of already wound turns is determined by an acquisition or counting element, not shown. From these values, a computing element 18 determines an expected actual value 9 of the coil height or axial winding layer height H. This is compared with the setpoint value 8 of the coil height or winding layer height H and a control device 10 calculates therefrom a manipulated variable for an actuator 11 of the deformation device 12 ,
- an automated control device 10 it is also possible to provide a manually operated control device 10.
- a manually operated control device 10 by means of an adjusting device to be changed manually, especially for the forming elements, in particular the pinch rollers of the deformation device 12, a change in the working values and an adaptation or exact approximation to the desired value 8 of the final winding layer height H can be achieved.
- the disturbance variables which act on the integrated overall process and thus influence the pitch of the conductors or conductor bundles 6 are denoted by 16 in FIG.
- These are in particular tolerances in the adjustment of the shaping elements, in particular the pinch rollers to changes in dimensions by the pressure relief after the squeezing rollers, especially when crushing conductor bundles, tolerances in the application of the outer insulation and deformation forces in the head or autism ⁇ bundle 6 during winding of the winding layer 1 or coil arise.
- the latter are dependent, among others, on the geometric dimensions of the conductor or conductor bundle 6 and the winding diameter.
- the method according to the invention also includes the possibility of realizing different pitches GH1, GH2, GH3 for these sections of the winding layer 1 by specifying target heights for specific winding sections within a winding layer 1. This is particularly useful for the consideration of different external insulation of the conductor or conductor bundle 6 for differently loaded winding sections. So it becomes e.g.
- FIG. 4 shows a schematic representation of a winding device 20 according to the invention.
- these conductors or conductor bundles successively pass through a device 12 for deformation and a device 14 for insulating the conductors or the conductor bundles 6 before they are wound at the point 15 to coil form or wound on a winding body and thus virtually "on-line” or continuously, ie processed without substantial interruptions or intermediate deposits to the corresponding winding layers 1 for electric choke coils
- the conductors or conductor bundles 6 processed with the winding device 20 can thereby be pressed by a pressing device 19 be pressed against each other at a certain, largely constant pressure.
- the winding device 20 allows automatic or semi-automatic or manually controlled deformation of the conductor or conductor bundle 6 to be wound as a function of the winding layer height H to be achieved without interposition or without curling of the conductor or conductor bundle taking place therebetween Winding layer 1 produced, wherein the adaptation or change of Ver ⁇ forming results of the deformation device 12 during the ongoing winding process, so that the deformation of the processed conductor or conductor bundle 6 is integrated into the process for the production of the electrical coil or winding layer 1.
- H finished winding layer height
- the control device 10 may therefore require at least partial interventions or operating procedures by a person or, depending on the integration of various sensors and / or actuators, be more or less automated.
- winding device 20 it is also possible to involve two or more conductors or conductor bundles 6 in parallel within a winding layer 1.
- winding device 20 it is also possible with the winding device 20 according to the invention to simultaneously wind two parallel conductors or conductor bundles 6 or to provide a multiple arrangement of the winding device 20 or its components.
- the illustration of three winding layers 1 according to FIG. 1 or FIG. 2 is also to be understood as an example. In particular, only one winding layer 1 or a plurality of winding layers 1 may be formed.
