Embodiment 1
[0028] Such as Figure 1-Figure 4 As shown, the auxiliary umbrella cover 100 of this embodiment is coated on the outside of the insulator 10. The insulator 10 includes at least one shed 20. The auxiliary umbrella cover 100 forms a storage cavity 113, and the storage cavity 113 accommodates at least a single piece of the shed 20. The auxiliary umbrella The cover 100 includes an umbrella cover main body 110, a first connecting part 120 and a second connecting part 130. The two ends of the umbrella cover main body 110 are respectively provided with a first connecting part 120 and a second connecting part 130. The first connecting part 120 can be inserted into the second connecting part. In the part 130, the auxiliary umbrella cover 100 is closed in the circumferential direction so that the umbrella skirt 20 is accommodated in the receiving cavity 113. The thickness of the overlapping area of the first connecting part 120 and the second connecting part 130 is consistent with the ...
Embodiment 2
[0043] Such as Figure 5-Figure 6 As shown, the present embodiment provides an auxiliary umbrella cover 200 , which is different from the auxiliary umbrella cover 100 in the structure of the umbrella cover body 210 , and other structures are the same as the auxiliary umbrella cover 100 , which will not be repeated here.
[0044] In this embodiment, the umbrella cover main body 210 includes a first main body 211 and a second main body 212 , and the first main body 211 and the second main body 212 are assembled into the umbrella cover main body 210 . The main body 210 of the umbrella cover is set separately, which can simplify the manufacturing mold and reduce the production cost; and during the installation process, especially when it is installed on a large-diameter insulator shed, the split umbrella cover is more flexible to install, convenient to construct, and can reduce the high altitude. job risk.
[0045] In this embodiment, the first body 211 and the second body 212 ha...
Embodiment 3
[0052] Such as Figure 7-Figure 9 As shown, the present embodiment provides an auxiliary umbrella cover 300 , which is different from the auxiliary umbrella cover 200 in the extension part 340 , and other structures are the same as those of the auxiliary umbrella cover 200 , which will not be repeated here.
[0053] In this embodiment, taking the first main body 311 as an example, the upper surfaces of the upper umbrella body 314 and the second connecting portion 330 extend outward from the umbrella tip of the auxiliary umbrella cover 300 to form an extension portion 340 . The setting of the extension part 340 can increase the creepage distance of the auxiliary umbrella cover 300 .
[0054] In other embodiments, the extension part may also be flush with the lower surface of the lower umbrella body and the second connecting part, both of which can increase the creepage distance of the auxiliary umbrella cover.
[0055] The auxiliary umbrella cover 300 in this embodiment is pro...

Abstract
The invention discloses an auxiliary umbrella cover which covers an insulator, the insulator comprises at least one umbrella skirt, an accommodating cavity is formed in the auxiliary umbrella cover, the accommodating cavity at least accommodates a single umbrella skirt, the auxiliary umbrella cover comprises an umbrella cover main body, a first connecting part and a second connecting part, and thetwo ends of the umbrella cover main body are respectively provided with the first connecting part and the second connecting part. The first connecting part can be inserted into the second connectingpart to enable the auxiliary umbrella cover to be closed in the circumferential direction so as to contain the umbrella skirt in the accommodating cavity, and the thickness of the overlapping area ofthe first connecting part and the second connecting part is consistent with that of the umbrella cover body so that the outer surface of the auxiliary umbrella cover can be in smooth transition. According to the product structure of the auxiliary umbrella cover, the inner diameter and the outer diameter of the auxiliary umbrella cover after installation can be adjusted within a certain range. Theinvention also discloses a mounting method of the auxiliary umbrella cover, and the mounting method of the auxiliary umbrella cover can realize that one set of auxiliary umbrella cover can satisfy themounting of different umbrella diameters on the conical insulator, and mounting is flexible and convenient.
Description
technical field [0001] The invention relates to the field of power transmission insulation equipment, in particular to an auxiliary umbrella cover and a method for installing the auxiliary umbrella cover. Background technique [0002] At present, insulators have been widely used in the power industry. The early insulators were usually porcelain insulators. With the deterioration of the atmospheric environment, the level of air pollution is getting higher and higher. Porcelain insulators continue to have pollution flashover accidents under the condition of pollution accumulation, causing huge losses to the power grid and seriously affecting the smooth operation of the power grid. . At the same time, due to problems such as heavy rain and icing, accidents such as rain flash and ice flash of porcelain insulators tend to occur frequently. [0003] The auxiliary umbrella cover in the prior art is formed by a combination of a main umbrella and an umbrella skirt strap. Once the ...
