Abstract
The utility model discloses a composite insulator, comprising an insulation core rod, a metal support head fixed on a top end of the insulation core rod, a metal fixed foot fixed on a bottom end of the insulation core rod, and an electrical isolation sheath of creepage prevention fixed on an outer wall of the insulation core rod. The electrical isolation sheath of creepage prevention is symmetrically provided with two bowl-shaped umbrella skirts with accommodating chambers; opening directions of the bowl-shaped accommodating chambers of umbrella skirts (8) are opposite to each other; and one opening of the bowl-shaped accommodating chamber of an umbrella skirt is arranged at a side end, far away from the other bowl-shaped umbrella skirt. According to the utility model, through the unique umbrella skirt structure design, dirt can be collected by the bowl-shaped umbrella skirt accommodating chamber at an upper end and can be washed away in a heavy rain, so that the phenomenon that a little amount of dirt accumulated on the umbrella skirt to influence the creepage performance is effectively avoided; and an outer wall of another bowl-shaped umbrella skirt protective zone can be used to rapidly evacuate rainwater fell on the composite insulator, so that a waterless dry state of an inner wall of the protective zone can be effectively guaranteed, and the creepage prevention performance is effectively guaranteed.
Description
Technical field
The utility model belongs to the electric armour clamp technical field, is specifically related to a kind of composite insulator.
Background technology
Composite insulator is made up of insulating sleeve and full skirt that the connection gold utensil at plug, plug two ends, mandrel outer coat, and emerging composite insulator is high-strength because of its light weight, good electrical property, to be easy to advantage such as maintenance widely-used by electric power system.The full skirt pattern of existing composite insulator all is to belong to " upper and lower structure "; The full skirt body of existing full skirt is single straightway, the revolving body in certain thickness cross section is arranged with center line; The top of full skirt body links to each other with sheath and stretches out with the inclination angle less than 30 degree; The insulated outer surface of full skirt body is made up of upper surface and lower surface, and the inclination angle of upper and lower surfaces is generally 18 degree or 10 degree.
This traditional full skirt body, because the inclination angle is less, rainwater can drench whole full skirt bodies, comprises the part below the full skirt; In addition, the dirt like birds droppings and so on can flow on each full skirt body on the insulating sleeve with rainwater; Cause its whole anti-creep electrical property to reduce significantly, accidents caused easily.
The utility model content
The purpose of the utility model provides a kind of composite insulator with preferable anti-creep electrical property.
The technical scheme that realizes the utility model purpose is: a kind of composite insulator, comprise insulation mandrel, be fixed on the insulation mandrel top the metal support head, be fixed on the metal fixing feet of insulation mandrel bottom and be fixed on the anti-creep electric insulation sheath on the insulation mandrel outer wall; Be arranged with two bowl-shape full skirts with containing cavity on the said anti-creep electric insulation sheath, the opening direction of said bowl-shape full skirt containing cavity 8 is opposite, and also promptly the containing cavity opening of a bowl-shape full skirt is positioned at its side away from another bowl-shape full skirt.
In the such scheme, said bowl-shape full skirt comprise from anti-creep electric insulation sheath periphery wall protrusion and the ring-type base that forms and from the ring-type base outboard end towards the guard plot that extends away from another bowl-shape full skirt direction.
In the such scheme, the outer surface of said guard plot is a taper seat.
In the such scheme, said guard plot and ring-type base enclose in the insulating sleeve periphery and form said containing cavity, and the degree of depth of said containing cavity is more than or equal to 5 centimetres.
In the such scheme, also be provided with a plurality of annular full skirts between said two bowl-shape full skirts, said each annular full skirt is to form from anti-creep electric insulation sheath periphery wall protrusion.
In the such scheme, the quantity of said annular full skirt is three, and the diameter of an annular full skirt in the middle of being positioned at is greater than the diameter of other two annular full skirts, and less than the maximum gauge of bowl-shape full skirt guard plot.
The utlity model has positive effect: (1) the utility model is through unique umbrella skirt construction design; Dirt can be positioned at the containing cavity of a bowl-shape full skirt of upper end and collect; And can in heavy rain, wash away, thereby effectively avoid because of influencing creepage performance on the less debris accumulation full skirt body; And can utilize the outer wall of another bowl-shape full skirt guard plot to drain the rainwater that falls above that fast, and can guarantee effectively that this guard plot inwall is in anhydrous drying regime, effectively guarantees the anti-creep electrical property.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Reference numeral is: insulation mandrel 1, metal support head 2, metal fixing feet 3, anti-creep electric insulation sheath 4, bowl-shape full skirt 5, ring-type base 6, guard plot 7, containing cavity 8, annular full skirt 9.
Embodiment
(embodiment 1)
Fig. 1 is a kind of structural representation of the utility model, has shown a kind of embodiment of the utility model.
Present embodiment is a kind of composite insulator, sees Fig. 1, comprise insulation mandrel 1, be fixed on insulation mandrel 1 top metal support head 2, be fixed on the metal fixing feet 3 of insulation mandrel 1 bottom and be fixed on the anti-creep electric insulation sheath 4 on insulation mandrel 1 outer wall.
Be arranged with two on the said anti-creep electric insulation sheath 4 and have the bowl-shape full skirt 5 of containing cavity 8 and three annular full skirts 9 between two bowl-shape full skirts 5.The opening direction of said bowl-shape full skirt containing cavity 8 is opposite, and also promptly containing cavity 8 openings of a bowl-shape full skirt 5 are positioned at its side away from another bowl-shape full skirt 5.
Said bowl-shape full skirt 5 comprise from anti-creep electric insulation sheath 4 periphery walls protrusions and the ring-type base 6 that forms and from the ring-type base 6 outboard ends towards the guard plot 7 that extends away from another bowl-shape full skirt 5 directions.
In order to make rainwater drain easily, the outer surface of said guard plot 7 is taper seats.
Said guard plot 7 encloses in insulating sleeve 4 peripheries with ring-type base 6 and forms said containing cavity 8, and the degree of depth of said containing cavity 8 is more than or equal to 5 centimetres.
Said each annular full skirt 9 is to form from anti-creep electric insulation sheath 4 periphery walls protrusion, and basic configuration is a tabular.
