Abstract
The utility model discloses an oil free dry type wall tube insulator, aiming to solve the shortcomings of the conventional horizontal type oiled paper insulated sleeve, including non-oil stain resistance and inconvenient maintenance. The oil free dry type wall tube insulator comprises an outdoor insulating cover and an indoor insulating cover; and is characterized in that the outdoor and the indoor insulating covers are silicon rubber insulating covers and filled with insulating medium, and the outer diameters of the outdoor and the indoor insulating covers are alternately arranged in the sequence of large diameter and small diameter. The oil free dry type wall tube insulator provided in the utility model can be used as a linking insulating device for high-voltage electric transmission and transformation equipment of 126kV and 252kV voltage classes.
Description
Technical field
The utility model relates to a kind of high pressure and connects seal, particularly a kind of no oily condenser type wall-through bushing insulator.
Background technology
In the connection seal of the high-tension power transmission and transformation equipment of 126kV, 252kV electric pressure, existing horizontal wall-through bushing insulator, be generally a kind of oil-paper condenser type insulating sleeve (as shown in Figure 1), the family of this traditional horizontal paper oil insulation sleeve pipe, internal and external insulating adopt the high tension insulator material, and indoors end is provided with fuel tank, makes that profile diameter is big, Heavy Weight; In addition because sleeve pipe is in oily operating condition is arranged, and sleeve pipe leakage of oil and then contaminated environment can occur, cause external insulation pollution flashover decreased performance, thus need often to clean, so installation and maintenance are very inconvenient.
Summary of the invention
At above situation, the utility model provides a kind of oil-free dry electric capacity wall-through bushing insulator, can overcome the defective of the existing not resistant of traditional oil immersion paper capacitor formula insulating sleeve, improves the security reliability of power equipment operation.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of no oily condenser type wall-through bushing insulator comprises outdoor insulative cover and indoor insulating case, it is characterized in that, described outdoor insulative cover and indoor insulating case are the silicon rubber insulation cover; Filling dielectric in the insulating case; Described open air, indoor insulating case external diameter are large and small umbrella structure alternately.
In the such scheme, described outdoor insulative cover and indoor insulating case can be cylindricality, and equal diameters.
Compare with existing traditional oil-paper wall-through bushing insulator, the advantage of sleeve pipe of the present utility model is: first, adopted the good silicon rubber insulation cover of anti-aging, anti-electric corrosion performance to substitute insulator, and filling dielectric in the insulating case, be solid insulation, realized that sleeve pipe does not have oily operational mode, solved the shortcoming that sleeve pipe leakage of oil and greasy dirt dye, therefore do not need cleaning, non-maintaining.The second, adopt the silicon rubber insulation cover to substitute insulator, the weight of product is alleviated greatly, and need not fuel tank and conservator, volume is littler, and installation and transportation are convenient.The weight of this sleeve pipe is about with 1/3rd of the oilpaper formula wall bushing weight of electric pressure, and volume reduces about 25%.The 3rd, outdoor, indoor insulating case external diameter adopts big umbellule cross structure, and sleeve pipe pollution flashover performance is good, is suitable for the extra heavy filthy area of IV level.The 4th, insulating case can adopt column construction, and diameter reduces, good looking appearance.
Description of drawings
Fig. 1 is a kind of structure chart of existing oil-paper condenser type wall-through bushing insulator.Among the figure: 1, outdoor terminal block; 2, conservator; 3, outdoor insulator; 4, mounting flange; 5, fuel tank; 6, indoor insulator; 7, indoor terminal block.
Fig. 2 is the structure chart of the utility model combined insulated dry electric capacity wall-through bushing insulator.Among the figure: 3 ', outdoor insulative cover; 6 ', indoor insulating case; 8, umbellule; 9, gamp.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, traditional oil-paper condenser type wall-through bushing insulator comprises the conservator 2 that is connected with outdoor insulator 3, outdoor insulator 3 is connected with indoor insulator 6 by mounting flange 4, indoors the indoor end of insulator 6 is equipped with fuel tank 5, changes because of the pressure that variations in temperature causes to regulate sleeve pipe internal transformer oil.The sleeve pipe of this structure is in oily operating condition, when leakage of oil occurring, not only pollutes the environment, and can cause external insulation pollution flashover decreased performance, and in addition, its external diameter is greater than 500mm, and weight is more than 1000 kilograms, is unfavorable for installation and maintenance.
As shown in Figure 2, a kind of no oily condenser type wall-through bushing insulator also is a dry type condenser type wall bushing, comprises outdoor insulative cover 3 ' and indoor insulating case 6 ', outdoor insulative cover 3 ' and indoor insulating case 6 ' are the silicon rubber insulation cover, connect by mounting flange 4 between two covers; Insulating case 3 ', 6 ' interior filling dielectric; It is that the silicon of basic glue is filled glue with fixed attention that this dielectric can adopt sulphurated siliastic; Become solid dielectric insulation after the cold curing,, reduced volume greatly and alleviated weight so new casing need not fuel tank 5 and conservator 2 among Fig. 1.In the present embodiment, out of doors, indoor insulating case 3 ', 6 ' external diameter be gamp 9, umbellule 8 along axle alternately a structure mutually, this structure helps improving the pollution flashover performance of sleeve pipe, as the extra heavy filthy area operation of applicable IV level.
Claims (3)
1. a no oily condenser type wall-through bushing insulator comprises outdoor insulative cover and indoor insulating case, it is characterized in that, described outdoor insulative cover and indoor insulating case are the silicon rubber insulation cover; Filling dielectric in the insulating case; Described open air, indoor insulating case external diameter are large and small umbrella structure alternately.
2. no oily condenser type wall-through bushing insulator as claimed in claim 1 is characterized in that, described outdoor insulative cover and indoor insulating case are cylindrical.
