Abstract
The utility model relates to a glass insulator which comprises a disc-shaped glass body, a steel foot and a steel cap; the middle of the disc-shaped glass body is provided with a bulged part, and a main umbrella skirt is arranged radially and obliquely along the edge of the lower end of the bulged part in an extending mode; the steel foot is glued to the inner side of the bulged part through adhesive; the inner cavity shape of the steel cap and the bulged part are adapted and glued through the adhesive; the edge of the lower end of the steel cap is radially and obliquely provided with a shade in an extending mode; the lower bottom surface of the shade is provided with an elastic rubber layer; and the elastic rubber layer and the upper end surface of the main umbrella skirt are fit. The insulator provided by the utility model can effectively prevent the pollution of pollutants of blown dust, rain water and the like on the main umbrella skirt of the glass body; additionally, after the lower end surface of the shade is provided with the elastic rubber layer, the rubber layer presses the upper surface of the main umbrella skirt tightly, dust and other pollutants are not attached and bonded in clearances on the upper surface of the main umbrella skirt; and moreover, the elastic rubber layer greatly increases the creepage distance of the glass insulator, the service life is prolonged effectively, and the glass insulator is reliable and practical.
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; And; Glass insulator in using now is in order to increase creepage distance; Generally all be employed in the mode that a plurality of umbrella ribs are set on the main chute skirt lower surface, but this kind mode is limited to the degree that increases creepage distance, can not well satisfy the situation under the various mal-conditions.
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 resistant and dodge performance and the glass insulator that increases creepage distance.
For realizing above-mentioned purpose; The utility model adopts a kind of glass insulator, comprises plate-like vitreum, steel pin and steel cap, has 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, and said steel cap cavity shape and said lug boss are adaptive and through the adhesive gummed, and wherein said steel cap lower edge radial skew extends and is provided with shade; This shade bottom surface is provided with elastic rubber layer, fits in said elastic rubber layer and said main chute skirt upper surface.
Concrete, said elastic rubber layer is fixed on the said shade lower surface through the mode of pasting.
Concrete, the lower surface of said main chute skirt is provided with a plurality of concentric umbrella ribs, and the height of said umbrella rib increases along with the increase of radius.
Through above-mentioned improvement to prior art, steel cap lower edge radial skew extend shade is set after, can effectively block of the pollution of pollutant such as travel fatigue rainwater to vitreum main chute skirt; And then avoided reducing the problem that the insulator resistant is dodged performance, the more important thing is, after the shade lower surface is provided with elastic rubber layer; When the steel cap is installed; Make this elastic rubber layer press main chute skirt upper surface, do not exist other pollutants such as dust to attach the gap that is bonded at main chute skirt upper surface, from physically having stopped the osmosis pollution of dust rainwater etc.; And; The insulating properties that elastic rubber layer has has also increased the creepage distance of glass insulator greatly, and and then effectively raise useful life, reliable and practical.
Description of drawings
Fig. 1 is the utility model embodiment front view.
Embodiment
As shown in Figure 1; 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, has lug boss 10 in the middle of the wherein said plate-like vitreum 1; And be provided with main chute skirt 11 along this lug boss 10 lower edge radial skews extension; 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, and said steel cap 3 lower edge radial skews extend and are provided with shade 30; These shade 30 bottom surfaces are provided with elastic rubber layer 31; In the present embodiment, said elastic rubber layer 31 is fixed on the said shade lower surface through the mode of pasting, and this elastic rubber layer 31 is fitted with said main chute skirt 11 upper surfaces.
Can know obviously that from Fig. 1 the lower surface of said main chute skirt 11 is provided with a plurality of concentric umbrella ribs 12, and the height of said umbrella rib 12 increases along with the increase of radius.
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.
