Abstract
The utility model relates to a glass insulator, which comprises a disc-like glass body, an insulation shielding case, a steel leg and a steel cap, wherein a boss is arranged in the middle of the disc-like glass body; a main umbrella skirt slants and extends along the edge of the lower end of the boss in the radial direction; the shape of the lower bottom surface of the insulation shielding case is matched with that of the upper bottom surface of the main umbrella skirt; a through hole is formed in the middle of the insulation shielding case; a convex insulating wall extends along the edge of the through hole in the axial direction; internal threads are arranged on the inner side of the insulating wall; the peripheral surface of the steel cap is provided with external threads; and the insulation shielding case is matched with threads between the inner threads in the insulating wall and the outer threads of the steel cap to be fixedly connected. By the insulation shielding case, pollution of dust in the air, rain and the like can be effectively prevented, and pollution flashover resistant performance of the insulation shielding case can be improved; and moreover, the glass insulator is connected to the steel cap through the threads, so that the glass insulator is convenient to assemble and maintain and is 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.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, a kind of simple in structure, easy accessibility is provided, and can effectively improves the glass insulator that resistant is dodged performance.
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 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; Wherein, Said glass insulator also includes the insulation shade, and the bottom surface shape of this insulation shade and the upper bottom surface of said main chute skirt adapt to, and the centre position of this insulation shade offers through hole; Edge along this through hole extends axially the assembly wall that is provided with convexity, and the medial surface of said assembly wall is provided with internal thread; Said steel cap outer peripheral face has external screw thread, and said insulation shade forms through the threaded engagement between the external screw thread of internal thread in this assembly wall and steel cap and is fastenedly connected.
Through above-mentioned improvement to prior art; Owing to be provided with the insulation shade; Therefore and the upper surface of the bottom surface of this insulation shade and main chute skirt adapts, and has effectively stopped pollutant such as rainwater dust to Vitrea pollution, and then effectively raises resistant and dodge performance; And the mounting means that adopting is threaded cooperates is simple in structure, modern design, and work such as easy disassembly and maintenance, reliable and practical.
Preferably, for the creepage distance that makes glass insulator is big as much as possible, 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.
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 glass insulator; Comprise plate-like vitreum 1, steel pin 2, steel cap 3, insulation shade 4, have 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 5; Said steel cap 3 cavity shapes and said lug boss 10 are adaptive and through adhesive 5 gummeds, the bottom surface shape of said insulation shade 4 and the adaptation of the upper bottom surface of said main chute skirt 11, and the centre position of this insulation shade 4 offers through hole; Edge along this through hole extends axially the assembly wall 40 that is provided with convexity, and the medial surface of said assembly wall 40 is provided with internal thread; Said steel cap 3 outer peripheral faces have external screw thread, and said insulation shade 4 forms through the threaded engagement between the external screw thread of internal thread in this assembly wall 40 and steel cap 3 and is fastenedly connected.
Can know obviously also that from Fig. 1 for the creepage distance that makes glass insulator is big as much as possible, in the present embodiment, 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.
