Description

Technical Field

[0001] The utility model relates to the technical field of line lightning protection devices, in particular to a lightning protection column type porcelain insulator. Background Art

[0002] An insulator is a special insulating control. It is a device that can withstand voltage and mechanical stress and is installed between conductors of different potentials or between conductors and grounding components. It can play an important role in overhead transmission lines. It is usually made of glass or ceramic. Insulators will not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions. There are many types of insulators with different shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting hardware. There are at least the following disadvantages in the use of existing lightning protection column porcelain insulators: existing porcelain insulators are usually fixedly connected to the insulator mounting frame. However, when the wind is strong, it will cause the wires to shake, and when the wires shake, it will produce a large impact force on the insulator shed, which can easily cause the shed to be damaged by large torque; and because it is easy to be hit by external debris on the shed when used outdoors, causing the shed to be damaged; therefore, we launched the lightning protection column porcelain insulator.
