Problems solved by technology

[0002] At present, the existing lightning protection devices for overhead insulated lines mostly use zinc oxide arresters, but there are the following problems: the protection range of zinc oxide arresters is small, and if the protection range needs to be increased, it must be installed on each pole. In order to reduce the investment cost, it is necessary to install auxiliary facilities such as cross arms on the original line, which is difficult to construct. This method has advantages for the protection of electrical equipment, but it is not suitable for use on distribution lines.

Abstract

The invention provides a lightning protection device with an overhead insulated line. The lightning protection device comprises an insulator, a zinc oxide lightning arrester, a drainage ring and a connection plate which are arranged on the overhead insulated line, wherein the zinc oxide lightning arrester consists of a compounded silicon rubber insulation jacket and a resistance valve plate arranged in the zinc oxide lightning arrester; the drainage ring consists of a connecting rod of which one end is fixed at the upper end of the zinc oxide lightning arrester and two stainless steel semicircles which are arranged at the other end of the connecting rod; the stainless steel semicircles are clamped on the middle column of the insulator; and the lower end of the zinc oxide lightning arrester is connected with the lower end of the insulator. The lightning protection device with the overhead insulated line has the advantages of scientific design, high practicability, simple structure and reliable lightning protection effect.

Description

technical field [0001] The invention relates to a lightning protection device, in particular to a lightning protection device for an overhead insulated line. Background technique [0002] At present, the existing lightning protection devices for overhead insulated lines mostly use zinc oxide arresters, but there are the following problems: the protection range of zinc oxide arresters is small, and if the protection range needs to be increased, it must be installed on each pole. In order to reduce the investment cost, it is necessary to install auxiliary facilities such as cross arms on the original line, which is difficult to construct. This method has advantages for the protection of electrical equipment, but it is not suitable for use on distribution lines. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The object of the present invention is to address the deficiencies of t...
