The stay comprises a base and a support portion; the base is a rectangular plate horizontally arranged in the front-back direction; the support portion is an elongated cylindrical part horizontally arranged in the front-back direction; the support portion is arranged in the middle of the upper end surface of the base; the support portion is provided with a left side surface, an upper end surface, a right side surface, a left upper arc-shaped portion, a right upper arc-shaped portion and a lower end surface; the lower end surface of the support portion is integrally connected with the upper end surface of the base; the left side surface of the support portion is connected with the upper end surface of the support portion in a smooth transition manner by the left upper arc-shaped portion of the support portion, and the right side surface of the support portion is connected with the upper end surface of the support portion in a smooth transition manner by the right upper arc-shaped portion of the support portion; and the length of the support portion in the front-back direction is identical to the length of the base, and the width of the support portion in the left-right direction is 2/3 of the width of the base in the left-right direction. The stay is simple in structure and good in bending resistance and insulating effect, can be fittingly mounted with an insulating cushion block conveniently, and is not easy to damage.
Description
Technical field
The utility model relates to the insulating component of transformer, is specifically related to a kind of coil stay for superhigh pressure or extra-high voltage transformer.
Background technology
Need to use more coil stay in superhigh pressure or the extra-high voltage transformer.The coil stay of common prior art, be generally vertical bar shape stay, when it in use was used with cross-over block, the practice commonly used was by glue the two to be bondd, its disadvantage one is more loaded down with trivial details when being construction, and the 2nd, glue bonds easy affected by environment and stay is come off.Also have at present and use T shape coil stay, with the fit system of cross-over block for pegging graft; Its weak point is: this type stay because the upper surface of its support portion and about be between two sides and substantially be an angle of 90 degrees vertical connection, two outstanding seamed edges of self-assembling formation, make this type coil stay when cooperating installation with cross-over block, very inconvenient, installation is wasted time and energy; And the cross-over block that damages coil stay or be mated easily when pegging graft, thereby have a strong impact on insulation effect.
The utility model content
The purpose of this utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, cooperate with cross-over block easy for installation, be difficult for the coil stay that is used for superhigh pressure or extra-high voltage transformer impaired and that insulation effect is good.
The technical solution of the utility model is: the coil stay for superhigh pressure or extra-high voltage transformer of the present utility model comprises base and support portion; Its design feature is: above-mentioned base is that front and back are to horizontally disposed rectangle plate body spare; The support portion is that front and back are to horizontally disposed strip cylindrical body part; The support portion is arranged on the upper surface of base between two parties; The support portion has left surface, upper surface, right flank, upper left curved portions, upper right curved portions and lower surface; The support portion is connected with the upper surface one of base by its lower surface; The upper left curved portions of support portion is connected smoothly by the upper end of its lower end and left surface; Upper left curved portions is connected smoothly by the left end of its upper right end and upper surface; The upper right curved portions of support portion is connected smoothly by the upper end of its lower end and right flank; Upper right curved portions is connected smoothly by the right-hand member of its top left end and upper surface.
Further scheme is: the sagittal length of above-mentioned support portion is identical with the sagittal length of base; About the support portion to width be base about to width 2/3.
The utlity model has positive effect: the coil stay for superhigh pressure or extra-high voltage transformer of the present utility model, simple in structure, cooperate with cross-over block easy for installation, be difficult for impaired and flexural strength and insulation effect better.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Reference numeral in the above-mentioned accompanying drawing is as follows:
Support portion 2, left surface 21, upper surface 22, right flank 23, upper left curved portions 24, upper right curved portions 25.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
(embodiment 1)
See Fig. 1 to Fig. 3, the coil stay that is used for superhigh pressure or extra-high voltage transformer of present embodiment is comprised of all-in-one-piece base 1 and support portion 2.
Support portion 2 is that front and back are to the strip cylindrical body part that arranges.Support portion 2 has left surface 21, upper surface 22, right flank 23, lower surface, front end face and rear end face.Support portion 2 is arranged on the upper surface of base 1 between two parties, and support portion 2 is connected with the upper surface one of base 1 by its lower surface; About support portion 2 to width be base 1 about to width 2/3.The sagittal length of support portion 2 is identical with base 1 sagittal length, also is that front end face and the rear end face of support portion 2 is corresponding on a vertical guide respectively with front end face and the rear end face of base 1.
Support portion 2 also has upper left curved portions 24 and upper right curved portions 25, and upper left curved portions 24 is connected smoothly by the upper end of its lower end and left surface 21; Upper left curved portions 24 is connected smoothly by the left end of its upper right end and upper surface 22;
The upper right curved portions 25 of support portion 2 is connected smoothly by the upper end of its lower end and right flank 22; Upper right curved portions 25 is connected smoothly by the right-hand member of its top left end and upper surface 22.
The material of aforesaid base 1 and support portion 5 is all for being formed by the bonding hot pressing of paper edge paper.
It is that raw material are through being made that the insulating paper of making aforesaid base 1 and support portion 2 adopts the wood pulp that does not float sulfate of high-purity, high-quality import.Be characterized in the shrinkage less, oil absorbency is relatively large; Flexural strength is better.
The coil stay that is used for superhigh pressure or extra-high voltage transformer of present embodiment, simple in structure, cooperate with cross-over block easy for installation, be difficult for impaired and flexural strength and insulation effect better.
Above embodiment is the explanation to embodiment of the present utility model; but not to restriction of the present utility model; person skilled in the relevant technique is in the situation that does not break away from spirit and scope of the present utility model; can also make various conversion and obtain the corresponding technical scheme that is equal to variation, so all technical schemes that are equal to all should be included into scope of patent protection of the present utility model.
