Abstract
The utility model provides a high-voltage coil for a transformer. The high-voltage coil for the transformer comprises a high-voltage coil body with round enamelled copper wires, the proportion of the diameter of the round enamelled copper wires on the inner layer and the outer layer of the high-voltage coil body to the diameter of the round enamelled copper wire on the middle layer of the high-voltage coil is set to be 2.0-2.2:1, so that the diameter of the round enamelled copper wires on the inner layer and the outer layer of the high-voltage coil body and the diameter of the round enamelled copper wire on the middle layer of the high-voltage coil are made to be different, the diameter of the round enamelled copper wires on the inner layer and the outer layer is larger, and the diameter of the round enamelled copper wire on the middle layer is smaller. The round copper wires are not wrapped by paper any more, the manufacturing process of the high-voltage coil is simplified, therefore, the stability performance of the structure of the high-voltage coil body is guaranteed, and the size accuracy of the high-voltage coil body is improved.
Description
Technical field
The utility model relates to a kind of high-tension coil, especially a kind of high-tension coil for S11-630/66 transformer.
Background technology
Transformer is widely used as large-scale power device, in order to guarantee the performance of transformer, just need to use high-voltage coil and low-voltage coil, therefore the high-tension coil for transformer is a kind of important transformer part, at the existing high-tension coil for S11-630/66 transformer, adopt the paper bag circular copper wire that turn insulation is 0.45mm to carry out coiling, because the insulation of paper bag circular copper wire is thicker, this kind of wire not only processed and coiling difficulty, easily loosening, the width that cannot guarantee coil to and axial dimension, make the structural instability of coil, cost of manufacture is also relatively high simultaneously.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of high-tension coil for S11-630/66 transformer, therefore the stability of structure that has guaranteed the body of high-tension coil, has improved the dimensional accuracy of the body of high-tension coil, and has reduced transformer cost.
For achieving the above object, the technical scheme that the utility model is taked is: include the body of the high-tension coil with enamel insulated round copper wire, the ratio setting of the diameter of the enamel insulated round copper wire in the intermediate layer of the diameter of the enamel insulated round copper wire of the ectonexine of the body of high-tension coil and the body of high-tension coil is 2.0-2.2:1.
The enamel insulated round copper wire of different-diameter size is turned to coil, owing to having designed enamel insulated round copper wire, make the ectonexine of body of high-tension coil not identical with the enamel insulated round copper wire diameter in intermediate layer, the enamel insulated round copper wire diameter enamel insulated round copper wire diameter large and intermediate layer of ectonexine is little, do not re-use paper bag circular copper wire, simplified the manufacture craft of high-tension coil, therefore guaranteed the stability of structure of the body of high-tension coil, improve the dimensional accuracy of the body of high-tension coil, and reduced transformer cost.
The utility model has designed, the enamel insulated round copper wire of the body of high-tension coil is set to include enamel insulated round copper wire I and enamel insulated round copper wire II, enamel insulated round copper wire II is set to be connected with enamel insulated round copper wire I, enamel insulated round copper wire I is arranged on the ectonexine of coil, enamel insulated round copper wire II is arranged on the intermediate layer of coil.
The utility model has designed, and the turn insulation thickness of enamel insulated round copper wire I 1 II 2 is set to 0.10-0.14mm.
In the technical program, the internal layer of coil refers to the initial ground floor of first coiling of the body of high-tension coil, and the skin of coil refers to one deck of last coiling of the body of high-tension coil.
In the technical program, it is important technical characterictic that high-tension coil is used enamel insulated round copper wire to replace paper bag circular copper wire and reduce turn insulation thickness, in the technical field of the high-tension coil for transformer, has novelty, creativeness and practicality.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Fig. 1 is first embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, include enamel insulated round copper wire I 1 and enamel insulated round copper wire II 2, enamel insulated round copper wire II 2 is set to be connected with enamel insulated round copper wire I 1, enamel insulated round copper wire I 1 is arranged on the ectonexine of coil, and enamel insulated round copper wire II 2 is arranged on the intermediate layer of coil.
In the present embodiment, the ratio setting of the diameter of the enamel insulated round copper wire of the diameter of enamel insulated round copper wire I 1 and enamel insulated round copper wire II 2 is 2.0:1.
In the present embodiment, the turn insulation thickness of enamel insulated round copper wire I 1 II 2 is set to 0.10mm, has replaced former paper bag circular copper wire turn insulation thickness 0.45mm.
Enamel insulated round copper wire I 1 first coiling internal layer, enamel insulated round copper wire I 1 and enamel insulated round copper wire II 2 are linked together, again enamel insulated round copper wire II 2 coilings intermediate layer, when complete skin of coiling, again enamel insulated round copper wire II 2 and enamel insulated round copper wire I 1 are linked together, the skin of enamel insulated round copper wire I 1 coiling.
Second embodiment of the present utility model, the ratio setting of the diameter of the enamel insulated round copper wire of the diameter of enamel insulated round copper wire I 1 and enamel insulated round copper wire II 2 is 2.2:1, the turn insulation thickness of enamel insulated round copper wire I 1 II 2 is 0.14mm.
