Abstract
The utility model discloses a kind of composite suspension type insulators inner core of new construction, it is characterized in that, at the outer surface of the extension dish (2) of insulator core (1), there is protruding or recessed additional surface (3).Its advantage is that the extension panel surface of composite insulator inner core is with protruding or recessed, when composite silicone rubber time, these protruding or recessed additional surfaces add the contact area that silicon rubber and composite insulator inner core extend panel surface, thus the adhesion added between composite suspension type insulators inner core and silicon rubber, improve bond strength therebetween, thus improve the durability of composite suspension type insulators.Through laboratory test, under similarity condition, the useful life of the composite suspension type insulators of structure of the present utility model can improve 10% to 25%.There is good application value.
Description
Technical field
The utility model belongs to the composite suspension type insulators used in high voltage power transmission and transforming circuit, is specifically a kind of composite suspension type insulators inner core of new construction.
Background technology
Now widely used composite suspension type insulators is generally make gold utensil again by silicon rubber with as after the inner core compound of skeleton.And the extension dish of composite insulator inner core is generally the umbrella skirt construction shape of using former porcelain or nature of glass insulator is complex as a whole as extension dish and silicon rubber, but because the surface of the extension dish of full skirt shape is smooth, so just cause silicon rubber and surface conjunction power deficiency unavoidably, cause silicon rubber delamination, bubbling and then have influence on normal use and decline in useful life, works the mischief to normal power transmission and transformation line.In order to overcome this problem, designer of the present utility model has done and has studied in earnest, proposes goal of the invention of the present utility model.
Summary of the invention
Goal of the invention of the present utility model is in order to putting forward in conjunction with unstable problem of overcoming that the deficiency of adhesion between the silicon rubber of above-mentioned existence and the extension dish of insulator heart produces.Namely a kind of composite suspension type insulators inner core of new construction is provided.
Technical solution of the present utility model realizes like this, the composite suspension type insulators inner core of this new construction, is characterized in that having protruding or recessed additional surface (3) at the outer surface of the extension dish (2) of insulator core (1).
Useful technique effect of the present utility model is: the extension panel surface of composite insulator inner core is with protruding or recessed, when composite silicone rubber time, these protruding or recessed additional surfaces add the contact area that silicon rubber and composite insulator inner core extend panel surface, thus the adhesion added between composite suspension type insulators inner core and silicon rubber, improve bond strength therebetween, thus improve the durability of composite suspension type insulators.Through laboratory test, under similarity condition, the useful life of the composite suspension type insulators of structure of the present utility model can improve 10% to 25%.There is good application value.

embodiment
Below in conjunction with the embodiment provided in accompanying drawing, structure of the present utility model and use are described in detail.With reference to accompanying drawing, the composite suspension type insulators inner core of this kind of new construction, it is characterized in that, at the outer surface of the extension dish (2) of insulator core (1), there is protruding or recessed additional surface (3).
In order to improve exploitativeness of the present utility model, additional surface can adopt the structure of following description, or the combination of these structures.
A kind of composite suspension type insulators inner core of the composite suspension type insulators inner core of described a kind of new construction, is characterized in that said additional surface (3) is spheroidal or elliposoidal or columniform projection or recessed.Or the combination of two of any two kinds in these three kinds of planforms, or three kinds of combinations.
The composite suspension type insulators inner core of described a kind of new construction, is characterized in that said additional surface (3) is triangular prism shaped projection or recessed.
The composite suspension type insulators inner core of described a kind of new construction, is characterized in that said additional surface (3) is the projection of four prism type or recessed.
The composite suspension type insulators inner core of described a kind of new construction, is characterized in that said additional surface (3) is the projection of hexagon or recessed.
The composite suspension type insulators inner core of described a kind of new construction, is characterized in that said additional surface (3) to be cross section is the projection of polygon-prism or recessed.
The composite suspension type insulators inner core of described a kind of new construction, is characterized in that said additional surface (3) is circular or the projection of prismatic combination or recessed.
The composite suspension type insulators inner core of described a kind of new construction, is characterized in that said additional surface (3) is circular by a circle or prismatic or recessed nested encloses prismatic or circular projection or recessed aggregate surface.
That is: additional surface can be all protruding or recessed, also can be protruding and recessedly arrange respectively or be spaced.
Under the structure of above-mentioned condition inspires, composite suspension type insulators inner core extends all should falling within inventive concept scope of the present utility model with the additional surface combination of irregular prism, cylinder of all rules of panel surface.
Further, the surface of shaggy erose insulator inner core also belongs to inventive concept category of the present utility model.
