Abstract

A transformer winding device, a method and a transformer are disclosed. The transformer winding winding device includes a rotary device configured to extend along an axis of rotation and configured to receive a transformer winding to be wound, at least one device configured to provide a plurality of insulation strips, and a comb-like guide device. The comb-like device is configured to deflect the plurality of insulation strips into at least one common winding plane and fed parallel to one another, at an angle to an axis of rotation, to the transformer winding to be wound. The comb-like guide device can include at least a first guide device element for a first group of insulation strips and a second guide device element for a second group of insulation strips, wherein the first and second guide device elements are offset with respect to one another in terms of axial length.

Claims (35)

1. A transformer winding winding device, comprising:

a rotary device configured to extend along an axis of rotation and configured to receive a transformer winding to be wound;

at least one device configured to provide a plurality of insulation strips; and

a comb-like guide device configured to deflect the plurality of insulation strips into at least one common winding plane to be fed parallel to one another, at an angle to an axis of rotation, to the transformer winding to be wound, wherein the comb-like guide device includes at least a first guide device element for a first group of insulation strips and a second guide device element for a second group of insulation strips, wherein the first and second guide device elements are offset with respect to one another in terms of axial length, and wherein the first and second groups are combined on the transformer winding to form a homogeneous layer, wherein a respective insulation strip in the first group is configured to be inserted into an interspace between two adjacent insulation strips in the second group.

2. The transformer winding winding device as claimed in claim 1 , wherein each of the plurality of insulation strips is identical.

3. The transformer winding winding device as claimed in claim 1 , wherein the first comb-like guide device and the second comb-like guide device each have prong-like spacer elements, whose width corresponds to a width of guide slots formed respectively between the prong-like spacer elements.

4. The transformer winding winding device as claimed in claim 3 , wherein the first comb-like guide device and the second comb-like guide device are each offset with respect to one another by one guide slot width.

5. The transformer winding winding device as claimed in claim 3 , wherein the width of the guide slots is equal to a width of the insulation strips.

6. The transformer winding winding device as claimed in claim 1 , wherein the transformer winding winding device comprises:

an impregnation device for the plurality of insulation strips.

7. The transformer winding winding device as claimed in claim 5 , wherein the impregnation device is a resin impregnation device.

8. The transformer winding winding device as claimed in claim 1 , wherein the transformer winding winding device comprises:

devices for providing and winding an electrical conductor.

9. The transformer winding winding device as claimed in claim 8 , wherein the transformer winding winding device is configured to provide synchronous winding of the plurality of insulation strips and the electrical conductor.

10. The transformer winding winding device as claimed in claim 1 , wherein the first guide device element and the second guide device element are formed by a double winding comb.

11. The transformer winding winding device as claimed in claim 1 , wherein the guide device is adjustable such that a feed angle of the plurality of insulation strips is adaptable.

12. The transformer winding winding device as claimed in claim 1 , wherein the guide device is movable along the axis of rotation.

13. The transformer winding winding device as claimed in claim 1 , comprising:

at least one hollow body.

14. A method of winding a transformer winding, the method comprising:

providing a rotary device configured to extend along an axis of rotation and configured to receive a transformer winding to be wound;

providing a plurality of insulation strips;

deflecting the plurality of insulation strips into at least one common winding plane to be fed parallel to one another, at an angle to an axis of rotation, to the transformer winding to be wound with a comb-like guide device, wherein the comb-like guide device includes at least a first guide device element for a first group of insulation strips and a second guide device element for a second group of insulation strips, wherein the first and second guide device elements are offset with respect to one another in terms of axial length; and

combining the first and second groups on the transformer winding to form a homogeneous layer, wherein a respective insulation strip in the first group is configured to be inserted into an interspace between two adjacent insulation strips in the second group.

15. The method of winding a transformer winding as claimed in claim 14 , wherein each of the plurality of insulation strips is identical.

16. The method of winding a transformer winding as claimed in claim 14 , wherein the first comb-like guide device and the second comb-like guide device each have prong-like spacer elements, whose width corresponds to a width of guide slots formed respectively between the prong-like spacer elements.

17. The method of winding a transformer winding as claimed in claim 14 , wherein the first comb-like guide device and the second comb-like guide device are each offset with respect to one another by one guide slot width.

18. The method of winding a transformer winding as claimed in claim 17 , wherein the width of the guide slots is equal to a width of the insulation strips.

19. A transformer winding, the winding comprising:

a transformer body having a plurality of insulating strips wound around the body by:

providing a rotary device configured to extend along an axis of rotation and configured to receive the transformer body to be wound;

providing the plurality of insulation strips;

deflecting the plurality of insulation strips into at least one common winding plane to be fed parallel to one another, at an angle to an axis of rotation, to the transformer winding to be wound with a comb-like guide device, and wherein the comb-like guide device includes at least a first guide device element for a first group of insulation strips and a second guide device element for a second group of insulation strips, wherein the first and second guide device elements are offset with respect to one another in terms of axial length; and

combining the first and second groups on the transformer winding to form a homogeneous layer, wherein a respective insulation strip in the first group is configured to be inserted into an interspace between two adjacent insulation strips in the second group.

20. The transformer winding as claimed in claim 19 , wherein transformer winding has a geometrically matched and alternating feed of adjacent insulation strips by the first guide device element and the second guide device element, and a homogenous insulation layer formed from the wound insulation strips.
