Winding fixing device
View Patent ↗A winding fixing device and method for a hollow-cylindrical high-voltage winding are disclosed, wherein the winding fixing device includes a pillar-like element having two axial ends, each of the two axial ends being configured to be connected to a respective retaining element which is arranged transversely with respect thereto. Each of the retaining elements is configured to be movable along the pillar-like element and detachable therefrom. A positioning region for arranging a hollow-cylindrical high-voltage winding is formed between the retaining elements, and spacing elements are configured to move axially along the pillar-like element. The spacing elements are configured to radially fix the hollow-cylindrical high-voltage winding when placed between the retaining elements by applying a tensile force to the retaining elements.
1. A winding fixing device for a hollow-cylindrical high-voltage winding, the winding fixing device comprising:
a pillar-like element having two axial ends, each of the two axial ends configured to be connected to a respective retaining element which is arranged transversely with respect thereto, wherein each of the retaining elements is configured to be movable along the pillar-like element and detachable therefrom;
a positioning region for arranging the hollow-cylindrical high-voltage winding, which is to be formed between the retaining elements; and
spacing elements configured to move axially along the pillar-like element, wherein the spacing elements are configured to radially fix the hollow-cylindrical high-voltage winding when placed between the retaining elements by applying a tensile force to the retaining elements,
wherein at least one of the spacing elements has a first base surface, which is arranged along the pillar-like element between two spacing elements with a protruding second base surface.
2. The winding fixing device as claimed in claim 1 , wherein at least one of the retaining elements is embodied in a plate-like fashion.
3. The winding fixing device as claimed in claim 1 , comprising:
at least one bearing element, which is provided on a side of a respective retaining element which faces the positioning region.
4. The winding fixing device as claimed in claim 1 , wherein the bearing elements and/or spacing elements are fabricated from wood.
5. The winding fixing device as claimed in claim 1 , wherein the retaining elements and/or the pillar-like element are fabricated from a metal.
6. The winding fixing device as claimed in claim 1 , comprising:
traction rods or traction cables configured to apply the tensile force between the retaining elements.
7. The winding fixing device as claimed in claim 6 , wherein the traction rods or traction cables are provided with a thread on at least one end.
8. The winding fixing device as claimed in claim 6 , wherein the retaining elements have a rectangular-like footprint, and the traction rods or traction cables comprises:
at least four external traction rods provided in external corner regions and at least four internal traction rods provided in a region around the pillar-like element.
9. The winding fixing device as claimed in claim 1 , comprising:
a diaphragm, wherein the positioning region is at least axially surrounded by the diaphragm.
10. A winding fixing device in combination with a hollow-cylindrical high-voltage winding, the winding fixing device comprising:
a pillar-like element having two axial ends, each of the two axial ends configured to be connected to a respective retaining element which is arranged transversely with respect thereto, wherein each of the retaining elements is configured to be movable along the pillar-like element and detachable therefrom;
a positioning region for arranging the hollow-cylindrical high-voltage winding, which is to be formed between the retaining elements;
spacing elements configured to move axially along the pillar-like element, wherein the spacing elements are configured to radially fix the hollow-cylindrical high-voltage winding when placed between the retaining elements by applying a tensile force to the retaining elements; and
clamping elements, which in combination with the spacing elements are arranged on an inner radius of the hollow-cylindrical high-voltage winding.
11. The winding fixing device as claimed in claim 10 , wherein the clamping elements are wedges.
12. The winding fixing device as claimed in claim 10 , wherein the winding fixing device is arranged in a lying position in a transportation container.
