Pluggable lightning arrester

Abstract

The invention discloses a pluggable lightning arrester, which comprises an upper plug and a lower plug which are arranged at the two ends of the lightning arrester, wherein the upper plug and the lower plug of the two ends are inserted and fixed in an upper-end and a lower-end sockets on a mounting frame when the arrester is installed, the mounting frame comprises two bending sections, the lower-end socket is installed at the end part of the lower section of the mounting frame, an insulator is installed at the upper section of the mounting frame, and the upper-end socket is installed at the end part of the insulator; and the mounting frame, the insulator and the lightning arrester form a closed quadrilateral structure. The arrester is convenient to install and dismantle, the arrester preventive test is carried out every year without cutting the power of users, no pole climbing with high level is needed, so the labor intensity and unsafe factors of workers are reduced, and the working safety is improved.

Description

technical field [0001] The invention relates to a plug-in lightning arrester. Background technique [0002] Surge arrester is one of the important equipment for preventing overvoltage in power system. Surge arresters are used for lightning protection of power grids and overvoltages. According to the preventive test regulations for electrical equipment, preventive tests must be performed on arresters every year to check the insulation integrity of arresters. [0003] At present, the installation of the lightning arrester in the power system is fixed on the high-end structure with bolts. When the preventive insulation test of the lightning arrester is carried out every year, it must be removed from the power supply for testing. In this way, there is a power outage to the user every year for the preventive test of the arrester, so the power supply reliability requirements for the user cannot be met. At the same time, when the arrester is tested, the labor intensity of the work...

Problems solved by technology

In this way, there is a power outage to the user every year for the preventive test of the arrester, so the power supply reliability requirements for the user cannot be met. At the same time, when the arrester is tested, the labor intensity of the workers climbing the pole is high, there are many unsafe factors, and it also affects the enterprise and social benefits.

[0004] Patent 200920159123.4 discloses a 10Kv plug-in lightning arrester, which can be disassembled without power failure. However, due to its unreasonable structural design, sometimes there will be poor contact, difficulty in disassembly and assembly, and even jamming, which is not conducive to popularization and application.
