Description
Technical Field
The utility model relates to an electric power manufacturing technical field especially relates to a three-dimensional support that oil-immersed transformer used.
Background
The inner support of the transformer is mainly used for fixing the lead, and supports with different specifications are used for forming a lead frame around the transformer coil. Because the electric field of the lead wire is unbalanced, the bracket inside the transformer must be made of laminated high-density paperboard with higher electrical performance. Most importantly, the frame needs to bear the dead weight of various leads, unbalanced vibration force is generated in the running process of the transformer, and the mechanical stability of the whole frame is very important, namely the support needs to have certain mechanical strength. Conventional racks are typically constructed from parallel sheets of high density paperboard laminated to different widths and thicknesses according to different weighing requirements. The traditional stent has two fatal weak points: 1. due to the fact that the size of the bracket is heavy and heavy due to weighing requirements, assembly difficulty is brought to operators. 2. Because the support adopts the parallel lamination mode, generally, people try to adopt the perpendicular lamination direction to punch holes when punching fixing holes on the support. The mechanical strength of the bracket is ensured. And once the need for reversal arises, it is necessary to make holes parallel to the lamination direction, which would considerably reduce the mechanical strength of the stent itself and even its cracking.
Disclosure of Invention
Aiming at the problems in the prior art, the utility model improves the structure of the bracket inside the transformer, adopts the bending type structural design, and is very simple and convenient to use; meanwhile, the weight of the bracket is reduced, and the manufacturing cost of the transformer is reduced while the operation of an operator is facilitated.

Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be obtained by a person skilled in the art without any inventive work based on the described embodiments of the present invention, belong to the protection scope of the present invention.
As shown in figure 1, the three-dimensional support for the ultra-high voltage transformer is characterized in that: the support comprises a support body 1 which is formed by hot pressing and has a bending section, wherein the support body comprises a first folding edge 10 and a second folding edge 11, the first folding edge 10 and the second folding edge 11 are connected through an arc-shaped connecting part 12, the structure of the support is improved in the embodiment, the support structure with the bending section is designed, when one folding edge is in a horizontal state for bearing pressure, bending stress is received by one folding edge, and shearing force is received by the other folding edge, so that the bearing capacity of the support is improved, and the bending resistance of the support is improved by 150% in the embodiment and a flat-plate-shaped support under the same width through tests; under the demand of same bending stress, the thickness of support body has effectively been reduced to the structure of this embodiment to reduce the quality of support body, reduced the raw and other materials cost of support, further, in the use, need drill on the support body, this embodiment is in the use, and the surface of the high density cardboard of drilling perpendicular to support body can not destroy the intensity of support body.
Further, as shown in fig. 2, the included angle formed by bending the bracket body 1 is 90 °, and preferably, the widths of the first folded edge and the second folded edge are the same, and the width of the first folded edge, which is commonly used in practical use, is 20-50 mm.
Further, the bracket body 1 is formed by stacking a plurality of high-density paperboard layers in parallel before hot press forming.
Further, the bending part of the bracket body 1 adopts circular arc transition, the local stress of the first folded edge and the second folded edge at the transition part can be reduced by adopting the circular arc transition, and meanwhile, the bracket body is convenient to form and process and produce.
To sum up, the utility model discloses following beneficial effect has:
the utility model improves the structure of the bracket inside the transformer, adopts the bending structural design, and has very simple and convenient use; meanwhile, the weight of the bracket is reduced, and the manufacturing cost of the transformer is reduced while the operation of an operator is facilitated.
