A lightning protection device

Abstract

The invention discloses a lightning protection device, which comprises a mounting base and a lightning arrester arranged on the mounting base, a first connecting plate is provided at the bottom of the lightning arrester, and a connecting plate is provided on the top of the mounting base to match the first connecting plate The connecting groove, the first connecting plate and the connecting groove are connected by a first bolt, the side wall of the mounting base is provided with a mounting groove, and the inner wall of the mounting groove is movably connected with a fixed plate and a first supporting plate , the fixing plate is arranged above the first supporting plate, a supporting member matching with the first supporting plate is provided in the installation groove, and the connecting part of the fixing plate is provided with a The elastic part turned into the installation groove; under the action of the first support plate, there is no need for multiple workers to assist in replacing the arrester, avoiding the danger of the arrester falling, making the operation of replacing the arrester more convenient and improving the replacement efficiency.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a lightning protection device. Background technique [0002] The most primitive lightning arrester is a horn-shaped gap, which appeared at the end of the 19th century and was used for overhead transmission lines to prevent lightning strikes from damaging equipment insulation and causing power outages, so it is called "lightning arrester". In the 1920s, aluminum arresters, oxide film arresters and pill arresters appeared. Tube arresters appeared in the 1930s. Silicon carbide arresters appeared in the 1950s. In the 1970s, metal oxide arresters appeared again. Modern high-voltage arresters are not only used to limit the overvoltage caused by lightning in the power system, but also used to limit the overvoltage caused by system operation. The arrester is used to protect electrical equipment from high transient overvoltage hazards and limit the freewheeling...

AI Technical Summary

Problems solved by technology

[0003] However, there are a lot of shortcomings in the existing box-shaped arrester. For example, the existing box-shaped arrester is not easy to install and disassemble. In the process of using the arrester, once the arrester is damaged, the arrester needs to be disassembled, and then a new arrester needs to be installed. , so as to facilitate better work between cable components, and also to facilitate the maintenance of the arrester, but the existing box-shaped arrester is not easy to disassemble, because the arrester itself is heavy and works at a high altitude, so that in the process of disassembly , requires multiple staff to carry out auxiliary work, otherwise the lightning arrester is prone to the danger of falling, which is not only time-consuming and labor-intensive, but also dangerous, thus reducing the efficiency of disassembly
