[0011]

However, in such a conventional winding method of the transformer coil by 60-degree winding, the winding start angle is 60 degrees, but the winding end angle is 30 degrees. There was a problem that the product ratio was bad.

An object of the present invention is to provide a winding method of a transformer coil by 60-degree winding which can improve the space factor.

[0013]

According to the present invention, the winding is first wound as the lowermost layer, and the first turn, the second turn, and the third turn are continuously wound, and then the winding is raised to the first turn and the second turn. Continue winding 4th turn in the upper groove between the eyes and 5th turn in the upper groove between the 2nd and 3rd turns, and then lower it and place it as the bottom layer next to the 3rd turn. Continue winding on the 7th and 7th turns, then raise it and repeat the above 3
Wind the 8th turn in the upper groove between the 6th turn and the 6th turn, and further raise it to make the 9th turn, the 5th turn and the 8th turn in the upper groove between the 4th turn and the 5th turn. Continue winding 10 turns in the upper groove between the eyes, then lower it and wind 11 times in the upper groove between the 6th and 7th turns, and further lower it to the 7th turn. Continue winding 12th and 13th turns as the bottom layer next to it, and then raise it and wind 14th turn in the upper groove between 7th turn and 12th turn. Wind the 15th turn in the upper groove between the 11th turn and the 11th turn, and further raise it to the 16th turn in the upper groove between the 9th turn and the 10th turn.
Continue winding the 17th turn around the upper groove between the 0th turn and the 15th turn, then lower it and wind the 18th turn around the upper groove between the 11th turn and the 14th turn,
It is further lowered to wind the 19th turn in the upper groove between the 12th turn and the 13th turn, and further lowered to wind the 20th turn and the 21st turn as the lowermost layer next to the 13th turn. The winding method of the transformer coil is improved by continuing the winding work, and performing the bale stacking winding with the 60 degree winding so that the winding start angle becomes 60 degrees from one side to the other side to form the transformer coil. It is a thing.

In the winding method of the transformer coil according to the present invention, the winding of the final turn at the end of the lowermost layer in the width direction by lowering the winding is performed in the widthwise direction of the already wound lowermost layer. Between the last turn and the last turn in the widthwise end of the bottom layer and the next turn of the bottom layer It is wound in the upper groove, then in the upper layer in sequence, and in the uppermost layer, it is wound two turns in a row from the back to the front, and then it is lowered and wound in the lower layer. When the winding of the end of the next layer next to the lower layer is completed, the work is raised and the work is sequentially performed on the layers above it.

By winding in this way, not only the winding start angle but also the winding end angle can be set to 60 degrees, and the space factor can be improved. Moreover, if the number of turns is the same, the transformer coil can be downsized.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a first example of an embodiment of a winding method for a transformer coil according to the present invention.

This example shows the order of a method of winding a transformer high voltage side coil of 66 turns by winding 60 degrees as in the conventional example. Also in this example, up to the 53rd turn, the winding method of the transformer coil by the conventional 60 degree winding is the same. This example is characterized in that the winding 1 is lowered and the winding is performed after the winding of the final turn at the end in the width direction of the lowermost layer.

That is, in this example, the winding of the final turn at the widthwise end of the lowermost layer by lowering the winding 1 is adjacent to the 43rd turn of the widthwise end of the already wound lowermost layer. To 2
Instead of continuing the winding, the 54th turn is wound only once.

Next, it is raised to the 54th turn, which is the final turn at the end of the bottom layer in the width direction, and the 4th turn of the bottom layer next to it.
The 55th turn is wound in the upper groove between the 3rd turn, the 56th turn is wound in the upper groove between the 44th turn and the 53rd turn in the upper stage, and then the upper turn is wound. Wind the 57th turn in the upper groove between the 45th turn and the 52nd turn of the step, and then turn the 46th turn and the 51st turn of the higher step.
The 58th turn is wound around the upper groove between the turns, and then the 59th, 50th and 58th turns of the uppermost layer are wound in the upper groove between the 47th turn and the 50th turn of the upper stage. Continue winding the 60th turn of the top layer in the upper groove between
Then, lower it to wind the 61st turn around the upper groove between the 51st and 57th turns, and further lower it to wind the 62nd turn around the upper groove between the 52nd and 56th turns and lower it further. Wind the 63rd turn in the upper groove between the 53rd and 55th turns.

Next, it is raised to wind the 64th turn around the upper groove between the 56th turn and the 63rd turn, and then the upper groove between the 57th turn and the 62nd turn of the stage above it. Then, the 65th turn is wound, and then the uppermost 66th turn is wound as the final turn in the upper groove between the 58th turn and the 61st turn in the upper stage.

By winding in this manner, not only the winding start angle but also the winding end angle can be set to 60 degrees, and the space factor can be improved.

Further, according to the winding method of the transformer coil by 60-degree winding according to the present invention, there is an advantage that the transformer coil can be miniaturized if the number of turns is the same.

When comparing FIG. 1 and FIG. 3 in which all the turns are 66 turns, the conventional transformer coil by 60 degree winding shown in FIG. 3 has a length of 16 turns, while FIG. The transformer coil formed by winding 60 degrees according to the present invention has a length of 14 turns, and the transformer coil can be miniaturized.

FIG. 2 shows a second example of the embodiment of the winding method of the transformer coil according to the present invention.

This example shows the order of the method of winding the transformer high voltage side coil by increasing the number of turns instead of the final number of 66 turns.

In this example, following the 66th turn, the 67th turn of the uppermost layer is wound in the upper groove between the 61st turn and the 65th turn, and then it is lowered to turn between the 62nd turn and the 64th turn. Wind the 68th turn in the upper groove, and then raise it and wind the 69th turn as the final turn in the upper groove between the 65th and 68th turns.

When wound in this manner, not only the winding start angle but also the winding end angle becomes 60 °, and the transformer coil has a trapezoidal cross section, and the space factor can be improved as compared with the first example.

[0028]

In the winding method of the transformer coil by 60-degree winding according to the present invention, the winding of the final turn in the widthwise end of the lowermost layer when the winding is lowered is already wound. The last turn of the widthwise end of the bottom layer and the bottommost layer next to the last turn of the bottommost layer are made to be a winding of one turn instead of two continuous turns next to the end of the bottommost layer in the width direction. It is wound in the upper groove between the turn and the next step, and then in the upper step in sequence, and in the uppermost step, it is wound two turns in a row next to each other from the back to the front, and then lowered to the step below it. When the end of the next stage next to the bottom layer is finished, raise it and wind it to the stage higher than that, so not only the winding start angle but also the winding end angle 60
The degree of space factor can be improved.

According to the winding method of the transformer coil by 60-degree winding according to the present invention, if the number of turns is the same,
There is an advantage that the transformer coil can be miniaturized.
