Definitions
- the invention relates to a method according to the preamble of claim 1 and a winding block for a coil of a transformer according to the preamble of claim 2.
- the entire insulation of a winding is in addition to the layer insulation between the turns of electrical wire or strip material of an edge insulation, which must be introduced at the end of the winding. Since with simultaneous winding for conductor material and insulation material only the same number of turns is available, the insulation at the end of the actual winding process must be subsequently introduced, which means an increased workload.
- the object of the invention is to provide a method of the aforementioned type for producing a winding block for a coil of a transformer, in which a subsequent introduction of a border insulation is no longer required.
- the windings of electrically conductive material are applied independently of the turns of the fiber rovings, in which a smaller number of fiber roving windings are applied when the predetermined number of turns of wire (windings of electrically conductive material) is applied. The remaining number of fiber rovings is then used for edge insulation.
- the number of fibers corresponding to that ninety turns will be counted below the number of turns of electrically conductive material, for example, about seventy turns of the insulating one material. This leaves - in the present example - twenty turns of insulating material "left over" which can be used for the edge insulation, thereby producing the edge insulation simultaneously with the production of the insulation and wire winding.
- Another object of the invention is to provide a winding block for a coil in which the method is realized.
- the winding block for the coil is characterized in that on the outside of the bobbin 10, a winding 16 of insulating material is applied, on which an inner winding portion 15i of electrically conductive material with a certain number of turns is wound, which on the inner portion 14i is applied a layer 15i of electrically insulating material, wherein the number of turns of electrically insulating material is smaller than the number of turns of the inner winding section 14 ⁇ so that the turns 15i and edge portions are wound.
- a further advantageous embodiment of the invention may be characterized in that the axial width of the turns of electrically conductive material is smaller than the axial width of the turns of electrically insulating material.
- a coil of the transformer has a tubular bobbin 10, at the ends of the coil flanges 11, 12 are attached.
- a winding 14 of electrically conductive material and insulating windings 15 of Faserrovingmaterial are wound onto the bobbin 10 within the spool flanges 11 and 12, to which then turns of wire of an inner winding section, also called inner layer 14i, are applied to the winding 14.
- the number of turns of wire, for example, of the inner layer 14i is "X", in one particular case one hundred turns covering a certain axial length, and an insulating layer 1 O 1 of fiber rovings is wound on the length of the layer 14T, the number of turns
- the number of turns For example, in the one-hundred-turn wire design, eighty turns are wrapped with fiber rovings Applying the insulating layer 15i of Faserrovingswindungen done independently, so that the different numbers of turns are achieved. Due to the different numbers of turns, with the surplus number of fiber roving windings, also the region D 1 and D 2 between the front ends of the layer 14i and the spool flanges 11, 12 can be wound with fiber rovings.
- the winding 14 has two further wire winding sections 14 2 and 14 3 , which lie radially outside the so-called inner layer ⁇ A ⁇ and radially outside the insulating layer 15i of the fiber rovings and end at a distance D3 to each other; Due to the smaller number of Faserrovingswindungen based on the wire turns can then be wound in addition to the areas D 1 and D 2 in a single operation, the range D3 readily. In this case, the axial length of each turn is smaller than the axial length of the relevant Faserrovingwindung, so that the coverage of the areas D 1 and D 2 and beyond the range D 3 is made possible.
- winding sections 14 2 and 14 3 also fiber rovings are wound, in the same way the number of turns of the fiber rovings is smaller than the number of turns of the winding sections 14 2 , 14 3 , so that the area D1 or D2 can be wound in one operation with insulating material.
- further winding sections are provided outside the winding sections 14 2 , 14 3 (without reference numerals), in which the winding with fiber rovings takes place in the same way as in the inner winding sections 14 i, 14 2 and 14 3 .
