AI Technical Summary

Technical Problem

Existing lightning protection insulators are expensive to manufacture, and directly replacing existing insulators on the line would be wasteful. There is a need for a lightning protection device that is simple in structure, highly applicable, and reusable.

Method used

A lightning protection insulator protection device was designed, including components such as an arc-starting rod, an arc-extinguishing ball, and a semi-cylindrical shell. The device achieves lightning protection through threaded connections and hinged structures. The device is independent of the insulator and can be disassembled and moved as needed.

Benefits of technology

This technology enables lightning protection retrofitting of post-type insulators, reduces the cost of power transmission line modification, and features a simple structure, strong applicability, and reusability.

Abstract

This utility model discloses a lightning protection insulator protection device, belonging to the technical field of electrical porcelain equipment. It includes an arc-starting rod, the threaded section at the head of which is threadedly connected to the central through-hole of a hollow bolt. The shank of the hollow bolt is rotatably connected to the through-hole seat on the front of the front half-cylinder shell. Symmetrical semi-grooves are opened on both sides of the half-cylinder shell, and a semi-circular hole is opened at the center of the bottom surface of the half-cylinder shell. The tops of the front and rear half-cylinder shells are hinged. The end of the arc-starting rod cooperates with an arc-extinguishing ball, which is installed on a clamp. After the front and rear half-cylinder shells are assembled, they can enclose the top hardware of the insulator. The cable mounted on the top of the hardware can pass through the assembled semi-grooves. The arc-starting rod contacts the hardware under the adjustment of the hollow bolt. The arc-extinguishing ball in the device is fixed to the steel foot of the insulator by the clamp, cooperating with the arc-starting rod in a distance, achieving the effect of lightning protection and pollution prevention. This device has a simple structure, strong applicability, and can be used for lightning protection retrofitting of post-type insulators.
