AI Technical Summary
The umbrella-shaped ice covering of traditional large-diameter hollow composite insulators is prone to form a bridge, resulting in the problem of discharge paths and external insulation flashover.
An anti-ice-covered umbrella structure is designed, including an insulating tube and an umbrella sleeve. The umbrella sleeve is equipped with several sections of parallel sleeves on the insulating tube. Each section of the umbrella sleeve is equipped with a large umbrella skirt and two small umbrella skirts. The spacing and inclination angle of the umbrella skirt have been optimized to increase the spacing between the umbrellas and prevent the ice chain and rain connection from forming discharge paths.
By optimizing the design of the umbrella cover, the ice chain and rain connection are effectively prevented from forming discharge paths, preventing external insulation flashovers, and improving the safety of insulators under ice-covered conditions.

Technical Field
[0001] The utility model relates to an ice - proof umbrella - shaped structure of a large - diameter hollow composite insulator. Background Art
[0002] When the traditional large - diameter hollow composite insulator (the inner diameter of the insulating tube is 1200 - 6000 mm) is covered with ice or snow on its umbrella - shaped part, due to the relatively close distance between the umbrellas, bridging is likely to occur, and it is easy to form a discharge path, thus causing external insulation flashover. Summary of the Invention
[0003] The utility model provides an ice - proof umbrella - shaped structure of a large - diameter hollow composite insulator to solve the problems existing in the above - mentioned prior art.
[0004] The technical solution adopted by the utility model is as follows:
[0005] An ice - proof umbrella - shaped structure of a large - diameter hollow composite insulator, the hollow composite insulator includes an insulating tube and an umbrella sleeve, the umbrella sleeve is sleeved on the insulating tube, the inner diameter of the insulating tube is 1200 - 6000 mm, the umbrella sleeve is provided with several segments and is sleeved on the insulating tube in parallel. Each segment of the umbrella sleeve is provided with a large umbrella skirt and two small umbrella skirts, and the distance between the two small umbrella skirts on each segment of the umbrella sleeve is equal to the distance between the large umbrella skirt and the adjacent small umbrella skirt on one side; for two parallel umbrella sleeves, the distance between the small umbrella skirt on one umbrella sleeve and the large umbrella skirt on the other umbrella sleeve is equal to the distance between the two small umbrella skirts on each segment of the umbrella sleeve.
[0006] Furthermore, the inclination angle of the small umbrella skirt is greater than that of the large umbrella skirt.
[0007] Furthermore, the distance between the two small umbrella skirts on each segment of the umbrella sleeve is at least 30 mm.
[0008] Furthermore, a stepped surface for assembly is provided between two adjacent segments of the umbrella sleeve.
[0009] The utility model has the following beneficial effects:
[0010] The utility model is applicable to large - diameter hollow composite insulators with an inner diameter of the insulating tube being 1200 - 6000 mm. Two small umbrellas are arranged between two large umbrellas of the umbrella sleeve, and each umbrella skirt has a certain inclination angle. The distance between adjacent large umbrellas is ≥90 mm, which increases the distance between the large umbrellas and prevents the formation of an ice chain and a rain chain to form a discharge path, belonging to an anti - ice - snow structure. Brief Description of the Drawings

[0012] Figure 2 It is an assembly drawing of two adjacent umbrella sleeves. Detailed Description of the Invention
[0013] The utility model is further described below in conjunction with the accompanying drawings.
[0014] like Figure 1 and Figure 2 The utility model discloses an anti-icing umbrella-shaped structure for a large-diameter hollow composite insulator. The hollow composite insulator comprises an insulating tube and an umbrella sleeve. The umbrella sleeve is sleeved on the insulating tube. The inner diameter of the insulating tube is 1200-6000 mm. The umbrella sleeve is provided with a plurality of sections, which are sleeved on the insulating tube in parallel. A large umbrella skirt 11 and two small umbrella skirts 12 are provided on each section of the umbrella sleeve. The inclination angle of the small umbrella skirt 12 is greater than the inclination angle of the large umbrella skirt 11.
[0015] The spacing between two small umbrella skirts 12 on each section umbrella cover is d, and d is at least 30mm. The spacing between the large umbrella skirt 11 and the small umbrella skirt 12 on the adjacent side on each section umbrella cover is also d.
[0016] For two parallel umbrella covers, the distance between the small umbrella skirt 12 on one umbrella cover and the large umbrella skirt 11 on the other adjacent umbrella cover is also d. Figure 1 .
[0017] A step surface 10 for assembly is provided between two adjacent sections of the umbrella cover, and sealant is directly provided on the two step surfaces to ensure the sealing of the assembly. Figure 2 .
[0018] Two small umbrellas are set between two large umbrellas. Each umbrella skirt has a certain inclination angle. The distance between adjacent large umbrellas is ≥90mm. The distance between the large umbrellas is increased to prevent ice chains and rain chains from forming discharge paths. It is an anti-ice and snow structure.
[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
