Falling type lightning arrester

Abstract

The invention relates to a falling type lightning arrester. The falling type lightning arrester comprises a ceramic insulator, a rainproof cap, a falling device and a zinc oxide lightning arrester main body, wherein the rainproof cap is provided with an inverted U-shaped part and two sheet-shaped guide parts; the inverted U-shaped part is internally provided with a conductive part; the falling device comprises a first conductive base and a second conductive base; the first conductive base is connected with the lower end of the ceramic insulator; the zinc oxide lightning arrester main body is connected with the second conductive base and is hung in a hook groove of the first conductive base through a hook of the second conductive base, so that the zinc oxide lightning arrester main body can rotate relative to the ceramic insulator. When the zinc oxide lightning arrester main body rotates upward relative to the ceramic insulator, the upper end of the zinc oxide lightning arrester main body enters the rainproof cap under the guide effect of the sheet-shaped guide parts and is in clamping joint with a clamping groove. The rainproof cap of the falling type lightning arrester provided by the invention is used for integrally combining a traditional rainproof cap and a guide fork so as to guarantee that the rainproof cap of the falling type lightning arrester has a guide function, and an assembling process can also be simplified, so that the production efficiency is easily improved.

Description

technical field [0001] The invention relates to a drop arrester. Background technique [0002] The technical idea of ​​the drop arrester is mainly derived from foreign countries, but many problems have appeared in the domestic application process. For example, the connection between the rainproof cap and the guide fork of the existing drop arrester is detachable, which may lead to The assembly process of the drop arrester becomes complicated, and it is not easy to improve production efficiency. Contents of the invention [0003] Based on the above problems, the purpose of the present invention is to provide a drop arrester, the rain cap used in it combines the traditional rain cap and the guide fork into one, to ensure that the rain cap of the drop arrester has a guiding function, and also The assembly process can be simplified, thereby easily improving production efficiency. [0004] The present invention provides a drop arrester, which includes: [0005] Ceramic insul...
