    A transformer winding, made as a layered winding with striplike conductor insulated with at least one strip of insulation folded about the conductor, and a process for making the same, are disclosed. To make possible a fully automatic manufacture of the winding with sufficient mechanical strength and uniform impregnation, the insulation strip, in addition to insulation of the conductor, constitutes likewise the insulation of the layers. At the periphery of a winding layer there are punctate bonding places at predetermined distances only on the outside of the conductor insulation. The cross section of the layered winding may be essentially trapezoidal with the transition to the free outer end comprising one or more circular arcs with different radii.

    .f The invention relates to a transformer multi-layer winding, preferably a high-voltage multi-layer winding, with a continuous ribbon conductor. The closest to the present invention is a transformer tape winding, the insulation of which is repaired by continuous insulating tape, the width of which is equal to three times the width of the ribbon conductor and laid around the conductor on one side in half l. The disadvantage of this transformer multilayer winding is that adhesive is hardened to insulate the conductor and at the same time the layers of paper. Although this measure leads to sufficient gluing of the paper insulation laid around the conductor, however, the reinforcement of the winding layers is provided only if the adhesive is applied to the insulating paper in the out of & so that a part of the adhesive material seeps through the folds of the folds and thereby glues the corresponding winding nearest sl. Such a method is unsuitable for imparting transformer multi-layer winding, preferably high-voltage multi-layer winding, to the necessary mechanical strength. Purposeful soaking is also difficult, since the gluing points between the individual layers are largely undefined. The purpose of the invention is to create a transformer multilayer winding, preferably a high voltage multilayer winding of the above type so that the mechanical strength is sufficiently high and with a large number of 4 layers of layers aimed at hardening the individual layers of the winding should also not interfere with impregnation. But first of all, a fully automated winding technique should be possible, preferably programmatically controlled. The goal is achieved by the fact that in order to automate the manufacture of multilayer winding with high mechanical strength, separate winding layers are formed by insulated tape conductors laid one on top of another without gaps, along the perimeter of one winding layer, dots are applied on the outer side of the insulation at a certain distance adhesive for fixing the layers of the winding, while the length of the layers of the winding from layer to layer is shorter so that the cross section of the multi-layer winding has a trapezoidal shape with colo oloobraznoy form the bottom of the winding adjacent to the winding axis, and the transition to the free outer end of a multilayer coil comprises one or several arcs. , with different radii. For a fully automated winding process, it is important that the insulation of the conductor is also the insulation of the layer at the same time. Due to this, there is no laborious rolling or prokidyvnye layer of insulation, significantly complicating and expensive manufacturing of known multilayer windings. It is also convenient that due to the bonding points of the dotted form, which are deliberately applied on the outside of the multilayer insulation, as a result, there is an exceptional hardening of the individual layers of the winding, and thus a compact design of the winding. At the same time, due to the gaps remaining between the glueing places, it is possible to sufficiently impregnate with liquid or gaseous impregnating agents. The coils of one layer, formed by insulated tape conductors, are stacked to one another by the end side without gaps along the winding axis. The use of tape conductors with a tape width significantly greater than its thickness makes it possible to backlash a layer on a layer without fear that the layer voltage, despite the absence of additional insulation of the layer, will become too large. The impregnation with liquid or gaseous impregnating agents also does not require a gap on the end side between the individual turns of one layer. On the other hand, the approximate production-related width of the gaps in fractions of a millimeter between the individual ends of the turns does not interfere and may even speed up the impregnation process; In addition, the insulating tape conductor is made of two insulating tapes, laid around the conductor. Due to double insulation, possible defects in the insulation tape are reliably compensated. FIG. Figures 1 and 2 show a cross section of a ribbon-like conductor with a single or double-fold insulating tape, the cross section is enlarged; in fig. 3 is a cross section of the layer winding; FIGS. 4-6 are variants of layer winding, partial pc13 cut; Fig. 7 shows a device for applying glue to layers of a winding. FIG. Figure 2 shows both layers 1 and 2 deposited on a ribbon-like conductor 3, preferably aluminum, and amp tape 4 to be wound around conductor 3. Insulation tape may consist of synthetic films or organic matter depending on the impregnating agent. such as cable paper or the like. Suitable preparation machines are, in particular, oil or gas, preferably hexafluoride j) a.Ha of FIG. 7, through the input rollers 5, the conductor 3 and the insulating tape 4 are fed to the multistage warehouses of the rolling device 7. The folding device. 7, together with the bypass roller 8 installed after it, ensures the fit of the insulating sheet 4, the width of which corresponds to approximately three times the width of the conductor around the conductor 3 under the same tension. The bypass roller 8 is located approximately vertically above the axis A of the winding of the coil frame 9, such as the insulated part of the conductor coming to the bypass roller 8 and the insulated part of the conductor moving away from the bypass roller 8 form an acute angle between 40 and 70. . This arrangement of the bypass roller 8 and the frame 9 favorably affects the covering of the conductor 3 with insulating tape 4. In the direction of us, shortly before the section where the insulated part of the conductor runs tangentially onto the already-wound layer of winding is located at least one adhesive device 10 by means of which a large number of glueing points can be applied on the outside of the already existing insulation of a coil of an earlier winding layer with a distribution around the perimeter of the coil. For the perimeter of the turn, it is preferable to provide for a compact winding design of from two to seven gluing points. In Figs. 3-6, the skeleton of a katuiki-represented multi-layer winding is designated by the position 11, respectively. Separate turns of 12 different layers of the winding adjoin each other on the ends. Without gap or with hardly visible small gaps. The individual turns 12 are covered only by insulating tape 4, as shown in FIG. 1. Isolation of layers between layers is absent. Insulation 4 turns of the conductor 3 is made so that the flat side 13 of the conductor, located outside the axis A of the winding, contains double with respect to the inside of the flat side 14 of the conductor (coating 15 of the insulating tape) coating 16 and 17 of the insulating tape. Since the ratio of the conductor to the thickness of the conductor is relatively large, for example, around 50: 1 to 100: 1, it can be seen that the width of the insulating tape 4 is at least approximately three times larger than the width of the tape-like conductor 3. The thickness of the conductor is practically can be neglected. The multilayer winding (Fig. 3) has lateral end surfaces 18 and 19, passing into the last layers with clearly pronounced arcs with radius K. The multilayer winding (figs. 4-6) may also have a profile deviating somewhat from the shape of the trapezium. Thus, the side face surface 20 may first pass through the form of the function i e, then go to the straight part before the arcuate portion with radius R goes to the last layers of the winding. In accordance with the form of execution (Fig. 5), the side end surface 21 can also be made in such a way that the winding part, passing by the form of the function i, goes directly to the arcuate part with radius R. In Fig. Figure 6 shows the form in which the lateral face surface 22 first passes strictly trapezoidal, and an arcuate part with different decreasing radii R,, R 2 and R e is attached to this part of the winding. To increase the mechanical strength of the multilayer winding in the quotient; With a large number of layers, it may be preferable to apply POINTS; gluing from turn to turn at different points of the perimeter of the turn. The radii defining the arcuate transitions to the free outer end of the multilayer winding are from 20 to 100 MM. The proposed multilayer windings are suitable for all types of transformers, in particular, measuring and test transformers, preferably for inductive voltage transformers. One of the main areas of application is inductive voltage transformers with hexafluorosulfur insulation. The multilayer winding makes it possible to rationalize the manufacturing process, since the whole process of isolation and winding can be fully automated from the first turn of the first layer to the last turn of the last layer. van through appropriate yogic-ramming control.
