Rain and snow prevention and bird damage prevention multifunctional lightning protection porcelain bottle insulator with safety cover

Abstract

A rain and snow prevention and bird damage prevention multifunctional lightning protection porcelain bottle insulator with a safety cover comprises a porcelain bottle insulator with a rain preventiondisc, a metal end is arranged at the upper end of the porcelain bottle insulator, a metal screw and a fixing nut are arranged on the axis of the lower end of the porcelain bottle insulator, and a jointing clamp is arranged at the top end of the metal end. One side of the metal end is connected with a lightning protection rod which is bent downwards, the lower end of the lightning protection rod isprovided with a discharge end facing the lower end of the insulator, and the lower part of the porcelain bottle insulator is provided with a discharge head; and the roots of the metal end, the jointing clamp and the lightning protection rod are all arranged in a safety cover. Herringbone spire tops are arranged at the tops of the safety cover and a power line protection tube, and spines are arranged on the spire tops. The rain and snow prevention and bird damage prevention multifunctional lightning protection porcelain bottle insulator has the advantages that the herringbone spire tops are arranged on the safety cover and the two ends of the safety cover, birds are prevented from falling off, bird nests are built, and bird damage is effectively prevented; the upper portion of the safety cover is of an integrated structure, and the sealing performance is improved; the grounding ring extends towards one side, and the strength of the connecting arm is increased, so that the grounding operation is facilitated; the metal end is made of an iron material, so that the metal end is firmly bonded with the porcelain bottle insulator, and the service life is prolonged; and an aluminum lightning protection rod connecting plate and the jointing clamp are utilized, so that the lightning protection effect is ensured.

Description

technical field [0001] The invention relates to a rain, snow and bird damage-proof multifunctional lightning-proof porcelain bottle insulator with a safety cover, which is used for supporting power transmission lines. Background technique [0002] Porcelain insulators are commonly used support components for power transmission lines. The main structure of the prior art includes a porcelain insulator with a rainproof plate. A metal end is provided on the upper end of the porcelain insulator, and a metal screw and a fixing nut are provided on the axis of the lower end. A terminal clip is provided on the top of the metal end. Some also connect one end of the terminal clamp to an electrical testing grounding ring through a connecting arm; a downwardly bent lightning rod is connected to one side of the metal end, and a discharge end facing the lower end of the insulator is provided at the lower end of the lightning rod. The lower part of the porcelain insulator is provided with ...

AI Technical Summary

Problems solved by technology

Its disadvantages are: the top is flat and has butt joints, rain and snow water drainage is not smooth, and it is easy to penetrate into the cover to cause corrosion of the metal parts inside the safety cover; the flat top of the safety cover and the top of the grounding ring for electrical testing are likely to cause bird damage ( Falling birds peck the cover, causing damage; building bird nests)

[0003] In addition, in order to improve the lightning protection effect, it is necessary to increase the conductivity of the lightning rod connected to it, and in order to reduce the cost, the metal end is generally made of aluminum, but the bonding structure between the aluminum metal end and the porcelain bottle insulator (adhesive Generally, cement or epoxy resin) is not firm, and it will loosen or even separate after a period of use, which will affect the safety of the line
