Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.See Fig. 4 to Fig. 6, continous way cake formula founds coiling structure, comprise magnet wire cake 2 and magnet wire cake 2 two ends are provided with insulating end ring 1, described magnet wire cake 2 is staggered successively from bottom to top by anti-cake 21 and positive cake 22 and forms, described anti-cake 21 and described positive cake 22 are by magnet strip superposition coiling in pie, and every one deck is a circle; The first cake of described magnet wire cake 2 is that anti-cake 21 is provided with the X that starts, end cake is that positive cake 22 has been provided with head A, the anti-cake 21 of first cake is connected by position, the end 23 with adjacent positive cake 22, and adjacent with next the again anti-cake 21 of this positive cake 22 is connected by vicinal 24, the like arrange the positive cake 22 of extremely last cake; Gap between described anti-cake 21 and described positive cake 22 is 1 ~ 4mm.
Described anti-cake 21 and described positive cake 22 are provided with centre tap therebetween.
embodiment:the utility model continous way cake formula is found coiling structure and is applicable to pouring dry transformer, one deck is a circle, tens circles become a cake, between cake, voltage is little, so only need very thin one deck clearance for insulation (1 ~ 4mm) to reach electric requirement between cake, thus reduce the height of coil, reduce volume.Save cost.
The continuous cake formula that the utility model is used for pouring dry transformer founds coiling structure (as shown in Figures 4 to 6), the positive cake 22 that the anti-cake 21 of first cake is provided with start X and last cake has been provided with head A, middle six cakes are tap section, upper three cakes are provided with three taps X1, X2, X3, and each cake of upper semisection all links together (positive and negative cake 22,21 replaces coiling); Lower three cakes are provided with three taps X4, X5, X6, and each cake of lower semisection all links together (positive and negative cake 22,21 replaces coiling).The positive and negative cake 22,21 of its a magnet wire cake 2 all from the inside to the outside circle is one deck, and radial superposition is in pie coiling between layers.
Fig. 5 is the magnet strip arrangement signal of tap section line cake, and can find out that one deck is a circle from the inside to the outside, radial superposition is in pie coiling between layers.
Fig. 6 is the three-dimensional structure diagram that the utility model pouring dry transformer continous way cake formula founds coiling structure, represents the architectural feature of coil visually.
The utility model is when the magnet strip of Transformer Selection stock size, and adopt continuous cake formula vertical around structure, coil axial height can be controlled better.In actual coiling, between cake, insulation can reduce.Compared with traditional structure, the use of material reduces, and the axial height of coil reduces.Due to adopt vertical around mode, the degree of packing of coil is well improved, can be greatly improved in mechanical properties, die-filling adjustment work for the later stage can reduce certain workload, more even in the field strength distribution of configuration aspects between cake, distribution for leakage flux is greatly improved, and obtains suitable improvement to the stray loss of transformer simultaneously.Consumption for the energy there has also been reduction to a certain degree.
Continuous cake formula of the present utility model is adopted to found coiling structure, show after test after tested, its turn-to-turn field strength distribution is even, axial height can reduce about 30mm, stray loss reduces, coil stray flux distribution obtains certain improvement, and there has also been reduction to a certain degree for the consumption of the energy.
