Embodiment Construction

[0012] like figure 1 Shown is a schematic diagram of the structure of the present invention, which is a cylindrical casing composed of two silicone rubber sheath pieces 1, which are arranged on the cylindrical casing corresponding to the position of the boss 3 at the sealant of the insulator There is a boss sheath body 2. like figure 2 Shown is a schematic structural diagram of a composite insulator, and its upper end 4 and lower end 5 of the insulator are both provided with bosses 3 for sealing. like image 3 As shown, the two sheath pieces 1 of the present invention are fastened on the composite insulator respectively, so that the boss sheath body 2 of the present invention corresponds to the boss 2 of the seal at the upper and lower ends of the composite insulator, and the two sheaths One end of the piece 1 bears against the umbrella group 6 at the end of the composite insulator, and the two silicone rubber sheath pieces 1 are bonded together with a silicone adhesive to...

Abstract

The invention relates to a sheath used for the compound insulator sealant of a high-voltage transmission line. The position of the boss is correspondingly provided with a boss sheath body. The invention is easy to install, and effectively avoids the problem that the composite mandrel is damp and the insulation performance is reduced caused by bird pecking at the sealing glue of the insulator. When the bird pecking damage is serious, the sheath of the present invention can be directly removed for replacement without replacing the entire insulator .

Description

technical field [0001] The invention relates to a sheath used for sealing glue of composite insulators of high-voltage transmission lines. technical background [0002] The insulation performance of the external insulation of 500kV transmission line is an important technical index for the safe and stable operation of the line. During the routine power outage inspection of the line, it is often found that there are bird pecks on the upper and lower end sealing glue of the composite insulator. The bird pecking on the sealing glue of the insulator will seriously reduce the insulation performance of the composite insulator. In severe cases, serious faults such as insulation breakdown and string detachment may occur. . Bird damage has become one of the adverse factors that plague the safe operation of power grid transmission lines, and it is also a technical problem that the current line profession is constantly exploring and urgently waiting to be solved. Conventional anti-bir...
