Electric system is also proposed higher requirement to electric property, the mechanical performance of porcelain bushing sleeve.
In general, the lifting of the electric property of insulated porcelain sleeve mainly meets that this is just by reasonably increasing size
So that high-tension power transmission and transformation equipment is with porcelain bushing sleeve, often air end insulator diameter, height are all larger.For these reasons, some factories
Family has even produced insulation height more than 9 meters, giant porcelain shell sleeve pipe of the weight more than 1.5 tons.This kind of insulated porcelain sleeve
Although easily up to standard on electrical specifications, because insulated porcelain sleeve primarily serves the effect of lead wire insulation in the product, pass through end
Face flange is attached with support section, due to the increase of insulated porcelain sleeve height and weight in itself, transport, in assembling process with
And after molding assembly and running a period of time, the porcelain body of insulated porcelain sleeve and the connecting portion of adpting flange are easily because machinery shakes
Dynamic, shock environment influences or the various extreme natural environment factors such as wind, rain, snow, sand influence and connecting portion is damaged,
Deformation, displacement or other damage phenomenons, cause the indexs such as product stability, reliability, service life, sensitivity significantly to drop
It is low.
Utility model content
The technical problem that the utility model solves is to provide a kind of high-strength insulation insulator, to solve above-mentioned background technology
The shortcomings that middle.
The technical problem that the utility model solves is realized using following technical scheme：

State connecting portion to be respectively arranged on both sides on the outside of the umbrella portion of porcelain body, for the assembly connection with adpting flange, it sets height
For 2 ~ 3 times of valve block hole aperture；Outer cylinder end face is provided with 6 ~ 10 inner groovies being arranged circumferentially；And the adpting flange
Height set 0.8 times of height for connecting portion, be provided with the ribs to match with inner groovy quantity and size on its internal diameter,
And embedding is carried out by epoxide-resin glue between adpting flange and connecting portion and fixed.
In the utility model, the inner groovy of the ring arrangement set on the outer cylinder end face is preferably 7 ~ 8.
In the utility model, the setting height of the inner groovy is the 2/3 of adpting flange height.
In the utility model, the groove profile vertical section of the inner groovy is preferably right-angled trapezium.
In the utility model, between the adpting flange and the connecting portion thickness of the epoxy resin of embedding be 3 ~
5mm。
In the utility model, shaping corresponding with the rigging position of the adpting flange on the lateral surface of the connecting portion
There is one layer of solid surface layer by diamond dust blasting treatment.
Beneficial effect：The utility model insulated porcelain sleeve is simple and reasonable, and cost of manufacture is cheap, by insulator connecting portion
Groove is done, and is attached in groove location by the adpting flange with corresponding ribs, and passes through epoxy resin after connection is molded
Carry out embedding to fix, effectively increase the toughness and intensity of connecting portion, be provided simultaneously with certain buckle resistance energy and impact property,
To meet the assembling demand of giant porcelain shell.
