Abstract
The utility model relates to a composite insulating outer sleeve of a novel umbrella skirt structure, which is suitable for various composite electric appliances used for high-tension transmission lines and electric substations. The composite insulating outer sleeve of a novel umbrella skirt structure comprises a suspender, a supporting post, a composite insulator of a cross arm, various lightning arresters and composite casing tubes, and the composite insulating outer sleeve of a novel umbrella skirt structure made of silastic insulating moulds is composed of a big umbrella skirt, a medium umbrella skirt and a small umbrella skirt which are arranged as one set. A plurality of combinations can form a composite insulating outer sleeve, and the difference of the diameters of the big, the medium and the small umbrella skirts is more than 30 mm. The improvement of the structure of the umbrella skirts enlarges the effective specific creepage distance of the composite electric appliance, the possibility of the bridging connection of sewage is reduced, the capability of resisting the pollution flashover of the composite electric appliances is enhanced, the distribution of the distances of the edges of the umbrella skirts is improved and external insulating flashover due to unexplained reason is reduced.
Description
Technical field
The utility model relates to a kind of composite insulation outer coat of novel umbrella skirt construction, is a kind of all kinds of compound electric apparatus that are used for ultra-high-tension power transmission line and transformer station: the insulating coating that comprises suspension type, pillar, cross-arm composite insulator, all kinds of compound lightning arrester and composite bushing.
Background technology
At present, produce both at home and abroad and the compound electric apparatus that uses all is partly to be made of core body, two client link gold utensils, silicon rubber full skirt overcoat three, silicon rubber full skirt overcoat plays a part the electrical equipment exterior insulation, and umbrella skirt construction is generally isometrical umbrella structure and large and small umbrella structure.According to compound electric apparatus hanging net operation accident investigation is for many years analyzed, a kind of external insulation flashover phenomenon of unknown cause appears in the compound electric apparatus of above-mentioned two class umbrella skirt constructions easily, this phenomenon mainly is because compound electric apparatus full skirt edge spacing distributes not too rationally, is subjected to the influence of filthy and voltage skewness and causes.The power system accident that causes thus is the problem that power industry is extremely paid close attention to.
Summary of the invention
The purpose of this utility model provides the composite insulation outer coat of the more rational a kind of novel full skirt of structure.
Concrete scheme of the present utility model is: a kind of composite insulation outer coat of novel umbrella skirt construction, make by the mold pressing of silicon rubber insulation material, by full skirt, a little full skirt in the big full skirt, is that one group of arrangement forms, a plurality ofly constitute a composite insulation outer coat, its arrangement is full skirt, a little full skirt in the big full skirt, in turn.
In the such scheme, the diameter of large, medium and small full skirt differs more than 30 millimeters.
The improvement of umbrella skirt construction had both increased the effective creepage than distance of compound electric apparatus, had reduced the possibility of sewage bridge joint, and the anti-soil that has improved compound electric apparatus dodges ability, has improved the distribution of full skirt edge spacing again, reduces the unknown cause external insulation flashover.

Embodiment
As shown in Figure 1, a kind of composite insulation outer coat of novel umbrella skirt construction, make by the mold pressing of silicon rubber insulation material, it is that one group of arrangement forms by full skirt 2, a umbellule skirt 3 in the big full skirt 1,, the diameter of large, medium and small full skirt generally differs more than 30 millimeters, a plurality ofly constitute a composite insulation outer coat, its arrangement is full skirt, a little full skirt in the big full skirt, in turn.
Claims (2)
1, a kind of composite insulation outer coat of novel umbrella skirt construction, make by the mold pressing of silicon rubber insulation material, it is characterized in that: by full skirt (2), a little full skirt (3) in the big full skirt (1), is that one group of arrangement forms, a plurality ofly constitute a composite insulation outer coat, its arrangement is full skirt, a little full skirt in the big full skirt, in turn.
2, composite insulation outer coat as claimed in claim 1 is characterized in that: the diameter of large, medium and small full skirt differs more than 30 millimeters.
