Abstract
The utility model relates to a glass insulator which comprises a disc-shaped glass body, a steel leg and a steel cap, wherein a bulge is formed in the middle of the disc-shaped glass body; a main umbrella skirt is arranged on the lower end edge of the bulge in a radially and obliquely-extending manner; the steel leg is glued on the inner side of the bulge through an adhesive; the inner cavity of the steel cap is matched with the bulge in shape and is glued through an adhesive; a plurality of flow guide grooves are radially formed on the upper surface of the main skirt umbrella; and every adjacent two flow guide grooves are in circular arc curved surface transition. The glass insulator has the benefits that as the flow guide grooves are radially formed on the upper surface of the main skirt umbrella, and every two adjacent flow guide grooves are in circular arc curved surface transition, the self-cleaning ability of the main umbrella skirt is improved, and further, the pollution flashover resistance of the glass insulator is improved; and meanwhile, due to the arrangement of the flow guide grooves and a circular arc curved surface, the maximum distance of the main umbrella skirt in the longitudinal direction is improved, therefore, the creepage distance of the glass insulator with the structure is increased.
Description
Technical field
The utility model relates to defeated, the power transformation equipment field of electric power, relates in particular to a kind of glass insulator.
Background technology
As everyone knows; The insulator of glass material is because its outstanding performance; Application on market is very general, and those skilled in the art should be known in because the continuous development of modern industry; Airborne pollution also increases the weight of gradually; Especially the influence to the glass insulator of power equipment equipment such as the utility model of using out of doors etc. is very big, and owing to in time remove and attach the pollutant that is bonded on the glass insulator and make the resistant sudden strain of a muscle performance reduction of the glass insulator in using, has influenced the useful life of insulator greatly.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, provides a kind of simple in structure, and can effectively improve the glass insulator that resistant is dodged performance.
For realizing above-mentioned purpose; The utility model adopts a kind of glass insulator; Comprise plate-like vitreum, steel pin and steel cap, have lug boss in the middle of the wherein said plate-like vitreum, and be provided with the main chute skirt along this lug boss lower edge radial skew extension; Said steel pin is glued at the inboard of said lug boss through adhesive; Said steel cap cavity shape and said lug boss are adaptive and pass through the adhesive gummed, and said main chute skirt upper surface radially offers several guiding gutters, circular arc camber transition between said every adjacent two guiding gutters.
Preferably, said guiding gutter is that fulcrum is distributed on said main chute skirt upper surface with the longitudinal center line.
Preferably, said guiding gutter quantity is preferably 12.
Through above-mentioned improvement to prior art; Radially offer the mode of circular arc camber transition between guiding gutter and the every adjacent guiding gutter at main chute skirt upper surface; In conjunction with the downward-sloping slightly characteristic of main chute skirt; As watt frame mode of formula eaves, can effectively improve the self-cleaning ability of main chute skirt, and and then the resistant that improves glass insulator dodge performance; Simultaneously, because the setting of guiding gutter and circular arc camber, it is many to make that main chute skirt ultimate range has in a longitudinal direction improved, and therefore, considers that from this angle the glass insulator of this kind shape and structure has increased creepage distance especially.

Fig. 1 is the utility model embodiment front view.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the partial sectional view of A-A direction among Fig. 2.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, the specific embodiment of the utility model is a kind of glass insulator, comprises plate-like vitreum 1, steel pin 2 and steel cap 3; Wherein can know to have lug boss 10 in the middle of the said plate-like vitreum 1 among Fig. 1, and along these lug boss 10 lower edge radially and slight inclination be provided with main chute skirt 11 to extending below; Said steel pin 2 is glued at the inboard of said lug boss 10 through adhesive 4, and said steel cap 3 cavity shapes and said lug boss 10 are adaptive and through adhesive 4 gummeds, can know in conjunction with Fig. 2 and Fig. 3; In the present embodiment; Said main chute skirt 11 upper surfaces radially offer 12 guiding gutters 110, and pass through circular arc camber 111 transition between every adjacent two guiding gutters 110, and are conspicuous; Guiding gutter 110 quantity can change arbitrarily, do not influence the protection range of the utility model.
Can know obviously also among Fig. 1 that said guiding gutter 110 is that fulcrum is distributed on said main chute skirt 11 upper surfaces with longitudinal center line 5.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The protection range that the utility model requires defines according to appended claim and equivalent thereof.
Claims (3)
1. glass insulator; Comprise plate-like vitreum, steel pin and steel cap; Has lug boss in the middle of the wherein said plate-like vitreum; And extend along this lug boss lower edge radial skew and to be provided with the main chute skirt, said steel pin is glued at the inboard of said lug boss through adhesive, and said steel cap cavity shape and said lug boss are adaptive and glue together through adhesive; It is characterized in that: said main chute skirt upper surface radially offers several guiding gutters, circular arc camber transition between said every adjacent two guiding gutters.
