Process for the production of a winding convoluted ring outlined soft paper cylinder arrangement for one high-voltage transformer and one wound from soft paper Tor, consisting of a layer winding with a layer of insulation fur which surrounds the winding radially, whereby Pez-shaped winding cross-section, each of which also has the insulating fur at its axial ends Layers is formed into angle rings at the ends of the layers in such a way that these wings torn soft paper cylinders separate kelrings each from the layer insulation and an iso-posed angle rings wound from soft paper, with double fur, which surrounds the winding radially, where you can see the angular rings that come from the layer insulation are formed in the insulating fur at its axial ends of adjacent layers and these is also formed into angular rings, such, angular rings opposite angular rings that that these angular rings are each formed from the layer of the insulating fur, insulating bar insulation manufactured angle hangers lie opposite. lie, with between the angular rings, which consist of 15 For transformers high voltage, z. B. for the layer insulation of adjacent layers formed test transformers, has the layer winding with and the continuously graduated layer length opposite these angular rings has proven successful, as Low angle rings that are made of the insulation fur in this winding with respect to the core or the are formed, insulation barriers are so that the boiler is largely even in the axial direction characterized in that in the iso 20 a moderate stress gradient can be achieved. This lation fur initially the layer with the largest construction but leads to a relatively large diameter and the smallest length between the winding and the boiler, there ben and with the interposition of Isolierstoffbar- the outermost layer of the winding also at the same time The layer insulation and the part of the Isola winding part that has the highest potion fur in operational terms is ure with the smallest diameter and 25 potential. of the smallest length formed into angular rings. is then to reduce the insulation fur with the winding and the boiler, it is most position is turned by 180 °, whereupon known, the winding with several hard paper raw Reshape the ends of the layer insulation and surround the ren. But since transformer windings associated part of the insulation fur under 30 gene for high voltage and large transformers Interposition of insulating material barriers on the power already considerable winding diameter Side of the other end of the layer takes place, then show, arise in the manufacture of hardboard Then pierce the next layer in the insulation fur, the diameter of which is still significant. is brought and then borrowed in the above about the diameters of the support tubes for the described way this layer insulation and 35 winding lie, considerable technological difficulties the associated part of the insulation fur under richen. In addition, insulation arrangements Introduction of insulating material barriers formed from a cross-layer of hard paper and oil what the renewed turning and the insist on, although better properties than pure oil tere processing and assembly takes place. stretch up; of the properties of an oil beverage 2. These arrangements are a method for producing a winding 40th soft paper insulation Arrangement according to claim 1, characterized by this but still far away (German patent specification draw ^ that on a support tube several 925 187, column 1). Winding layers are applied, between a winding is also known in which the insulation each of which has an insulating layer made of soft pallet between the layers and made of soft paper pier, and that these layers together in the 45 as well as from folded or crepe paper (German Isolation fur can be brought in. see interpretation 1 209 203). The folding paper 3. Process for the production of a winding paper or the crepe paper is also with the Arrangement according to claim 1 or 2, thereby continuously shortened layer length indicates that the winding is wrapped around the individual layers and envelops the winding order Insulation layers made of soft paper 50 lung completely. This winding arrangement has are outlined in each case with an angle ring with regard to their electrical strength and that between these angular lengths only parts compared to the arrangement that consists of a a barrier is inserted. Cross-layering of hard paper and oil with relative 4. There is a method for the production of a winding thick layer; but it comes to the Arrangement according to Claim 2, characterized in that 55 extremely favorable values are those soaked with oil draws that a soft paper insulation arrangements have on each one support tube, not odd number of winding layers applied. In addition, the major disadvantage is the will. This arrangement that the oil does not get through the winding 5. A method for producing a winding can flow through it. So this solution is based on a winding arrangement according to claim], characterized by limited 60 lungs with relatively small power loss, shows that the layers are vertical - but an arrangement is already known the insulation fur can be introduced. where the one executed with continuously shortened layer length Winding from one to a support tube wrapped insulating fur surrounded by soft paper 65 is. With this arrangement, the soft paper winding The invention relates to a method for producing kcl which lie between the individual layers and which development of a winding arrangement for a high-voltage layer exceed the length of the layers, voltage transformer, consisting of a layer wound.
