Description
Technical field
The utility model is related to a kind of end circle of cushion block with oblique angle.
Background technology
The insulation of oil-immersed transformer end turn and main empty path using square ring, end circle cooperate, with improve coil it
Between dielectric strength and mechanical stability.Square ring in order to allow end turn coincide as possible with equipotential line, the facade of square ring and bottom
Generally using arc transition, the inside radius of circular arc has two kinds of 10mm, 15mm in face.
Invention content
The utility model finds that the end circle inside square ring circular arc can withstand on square ring circular arc or even damage by pressure square ring, causes
Failure of insulation makes improvement for the technical issues of above-mentioned discovery, i.e., the technical problem to be solved by the utility model is to provide
A kind of end circle of cushion block with oblique angle, can not only avoid square ring from damaging, but also can play good position-limiting action with subtending ring.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：End circle of the cushion block with oblique angle, including paper
Circle and cushion block, cushion block are arranged on paper circle, and cushion block sets oblique angle with paper circle abutted surface close to paper circle inner radius, and cushion block protrudes paper circle
Interior edge；End circle is arranged in square ring, and cushion block protrudes the facade of the side limiting square ring on edge in paper circle, and paper circle is arranged on the bottom of square ring
On face.
Further, the cushion block is evenly distributed on paper circle.
Further, cushion block is located at paper circle upper surface close to the side of paper circle outer.
Preferably, the width of cushion block is 50mm or 60mm or 70mm, and for thickness between 20mm to 100mm, cushion block protrudes paper
The length on edge is 10mm or 15mm in circle, and for cushion block close to the lateral distance paper circle outer 1mm of paper circle outer, the oblique angle is 45 °.
Compared with prior art, the utility model has the advantages that：Paper circle and cushion block can perfection avoid square ring
Circular arc avoids square ring damage；Can be close to square ring facade on the inside of cushion block, subtending ring plays good limiting.
Description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment；
Fig. 2 is the schematic diagram in A-A direction of the utility model embodiment.
In figure：1- paper circles, 2- cushion blocks, 3- square rings.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
End circle of the cushion block with oblique angle, including paper circle and cushion block, cushion block is arranged on paper circle, and cushion block is leaned on paper circle abutted surface
Nearly paper circle inner radius setting oblique angle, cushion block protrude edge in paper circle；End circle is arranged in square ring, and cushion block protrudes the side on edge in paper circle
The facade of square ring is limited, paper circle is arranged on the bottom surface of square ring.
Further, the cushion block is evenly distributed on paper circle.
Further, cushion block is located at paper circle upper surface close to the side of paper circle outer.
Preferably, the width of cushion block is 50mm or 60mm or 70mm, and for thickness between 20mm to 100mm, cushion block protrudes paper
The length on edge is 10mm or 15mm in circle, and for cushion block close to the lateral distance paper circle outer 1mm of paper circle outer, the oblique angle is 45 °.
Further, the manufacturing method of end circle of the cushion block with oblique angle, cushion block are set with paper circle abutted surface close to paper circle inner radius
Oblique angle is set to, cushion block protrudes edge in paper circle, cushion block is arranged on paper circle according to above-mentioned set-up mode.
Further, paper circle is obtained by shearing cardboard, cushion block is obtained by hot-forming cardboard；Cut cushion block bottom surface with
The angle of one side makes oblique angle.
Further, cushion block is uniformly sticked on paper circle.
As shown in the figure, end circle is bonded by paper circle and cushion block.According to paper circle inner and outer diameter d and D size, using 2mm or
The cardboard shearing of 3mm thickness.Sticky pad block on paper circle face, quantity is depending on paper loop diameter, and generally 8,10,12,16,20,24,28
Etc., even circumferential distribution.Cushion block is hot-forming by cardboard, and width W has tri- kinds of 50mm, 60mm, 70mm, and thickness b is according to coil
Structure depending on, generally between 20mm to 100mm.Corresponding to the radius of square ring circular arc, edge in paper circle is extend on the inside of cushion block
Length has two kinds of 10mm, 15mm；From paper circle outer 1mm on the outside of cushion block.As shown in A-A sectional views, cushion block is stretched into paper circle along portion
Divide the chamfering of 45 ° of beveling.
The usefulness of this structure：Paper circle and cushion block can perfection avoid square ring circular arc, avoid square ring damage；In cushion block
Side can be close to square ring facade, and subtending ring plays good limiting.
The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the claims it is equal
Deng variation and modification, it should all belong to the covering scope of the utility model.
