Abstract
The utility model discloses a kind of round platform top composite suspension type insulators inner core of aggregate surface, there is the insulator core (1) of truncated cone-shaped top and extension dish (2), it is characterized in that, at the outer surface of the extension dish (2) of insulator core (1), there is protruding or recessed aggregate 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 aggregate 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 round platform top composite suspension type insulators inner core of aggregate surface.
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 round platform top composite suspension type insulators inner core of aggregate surface is provided.
Technical solution of the present utility model realizes like this, the round platform top composite suspension type insulators inner core of this aggregate surface, there is the insulator core (1) of truncated cone-shaped top and extension dish (2), it is characterized in that, at the outer surface of the extension dish (2) of insulator core (1), there is protruding or recessed aggregate surface (3).
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 aggregate 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.
Accompanying drawing explanation
Accompanying drawing 1 is the structural front view of the straight groove of round platform top composite suspension type insulators inner core of aggregate surface of the present utility model, and accompanying drawing 2 is vertical views of accompanying drawing 1, and accompanying drawing 3 is upward views of accompanying drawing 1; Accompanying drawing 4 is straight protruding front views of round platform top composite suspension type insulators inner core of a kind of aggregate surface of the present utility model, and accompanying drawing 5 is vertical views of accompanying drawing 4, and accompanying drawing 6 is upward views of accompanying drawing 4.Accompanying drawing 7 is vertical views of the another kind of structure of accompanying drawing 1 or accompanying drawing 4.Sequence number in accompanying drawing is illustrated as: 1, composite insulator inner core, and 2, extension dish, 3, aggregate surface, 4, continuously groove or protruding continuously.
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 round platform top composite suspension type insulators inner core of this kind of aggregate surface, there is the insulator core (1) of truncated cone-shaped top and extension dish (2), it is characterized in that, at the outer surface of the extension dish (2) of insulator core (1), there is protruding or recessed aggregate surface (3).
In order to improve exploitativeness of the present utility model, aggregate surface can adopt the structure of following description, or the combination of these structures.
The straight groove of aggregate surface or straight projection can be all protruding or groove, also can be protruding and recessedly arrange respectively or be spaced.
In order to make Design and manufacture and in use smooth and easy, at the upper surface of the extension dish (2) of said insulator core (1), at least there is one group of continuous groove extending to extension dish side or continuously protruding (4).This groove or projection, relative to the center radioactive ray profile design of extension dish, to improve serviceability and the simplified manufacturing technique of this structure, reduce costs.
Under the structure of above-mentioned condition inspires, the rule that the surface of the round platform top composite suspension type insulators inner core extension dish of aggregate surface is all with irregular straight connected in star and straight shape is protruding or its combination forms aggregate surface and all should fall within inventive concept scope of the present utility model.
Further, the surface of the round platform top composite suspension type insulators inner core of shaggy erose aggregate surface also belongs to inventive concept category of the present utility model.
The round platform of the round platform top composite suspension type insulators inner core of aggregate surface is generally inverted round stage, and namely the microcephaly of round platform is connected with extension dish.
Claims (2)
1. the round platform top composite suspension type insulators inner core of an aggregate surface, there is the insulator core (1) of truncated cone-shaped top and extension dish (2), it is characterized in that, at the outer surface of the extension dish (2) of insulator core (1), there is protruding or recessed aggregate surface (3).
2., according to the round platform top composite suspension type insulators inner core of a kind of aggregate surface according to claim 1, it is characterized in that having one group at the upper surface of the extension dish (2) of said insulator core (1) extends to the continuous groove of extension dish side or continuous protruding (4).
