Equal to tapered end insulation microcephaly width, place mat interlayer insulating paper, subsequently by wire and parallel side end insulation side by side coiling it is complete
Into the first circle of the second layer；
(3) afterbody in the first circle of the second layer is replaced, by first S along second layer coil winding direction curved with the
Straightway between two S are curved is ridden on the wire of the first circle of the second layer；
(4) replace after the completion of the second circle of the second layer colligation hypotenuse joint filling paperboard strip of starting, hypotenuse joint filling paperboard strip
Hypotenuse is contacted with the wire of the second circle of the second layer, forms the helix of second layer coiling, by wire and hypotenuse joint filling paperboard strip
Coiling side by side completes the second circle of the second layer；
(5) wire along helix on ground floor coil from tail to head coiling second layer remainder, complete the second layer line
The coiling of circle.
The part of wire coiling to first S remaining non-coilings of cutting hypotenuse joint filling paperboard strip when curved in step (4), will be oblique
Fix with conducting wire binding at the cutting of side joint filling paperboard strip, complete the second circle of the second layer.
The length of the parallel side end insulation is identical with the length of the second layer the first circle wire.
As shown from the above technical solution, the coiling of the laminar distribution transformer coils of the radial several paralleled conductor that the present invention is provided
Method, with two-layer coil as a unit, carries out coil transposition in the afterbody of first circle of the second layer of a unit, compared to existing
There is distribution transformer coils portion's transposition in each layer, the height of the coil of coiling molding is than the coil of middle transposition coiling molding
Highly little wire turn height, it is possible to decrease the totle drilling cost of distribution transformer 3%, while reducing the volume of distribution transformer.
The present invention will be first S along second layer coil winding direction curved and between second S is curved after coil transposition
Straightway is ridden on the wire of the first circle of the second layer, it is to avoid is caused wire to overlap and is caused thickness to increase, while coil transposition is produced
Room it is less, it is not necessary to extra choker block.
In the distribution transformer coils winding method provided in the present invention, in the first layer line of the two-layer coil of a unit
The colligation tapered end insulation of starting of circle second from the bottom is enclosed, with a hypotenuse, this is oblique after tapered end insulation coiling for tapered end insulation
Side forms helix, and the helix is matched with the helix of ground floor coil, completes ground floor coil for auxiliary last
The coiling of two circles so that ground floor coil winding closely, and then shortens coil axial length；The colligation of starting of the first circle of the second layer
Parallel side end insulation, compared to existing upper and lower ends using the distribution transformer coils of tapered end insulation, the present invention is using wide
Parallel side end insulation of the degree equal to the little head width of tapered end insulation, it is possible to decrease the overall 1 circle coil height of coil；After the completion of transposition
The colligation hypotenuse joint filling paperboard strip of starting of the second circle of the second layer, hypotenuse joint filling paperboard strip have a hypotenuse, in hypotenuse joint filling cardboard
After bar coiling, the hypotenuse forms helix, and the helix is the helix of second layer coil and matches, while hypotenuse joint filling
Paperboard strip forms space when being filled with wire transposition, makes coil winding closely, no local defect.
