Lightning arrester

Abstract

The invention discloses a lightning arrester. The lightning arrester comprises a telegraph pole, and a locking mechanism is arranged on the left end surface of the telegraph pole. The locking mechanism comprises a supporting plate, a supporting block is fixedly connected to the upper end surface of the supporting plate, a supporting hole is formed in the supporting block, and the upper and lower end walls of the supporting hole penetrate through the upper and lower end surfaces of the supporting block. An air pressure groove is formed in the left end surface of the supporting block, and the left end wall of the air pressure groove communicates with the outside space. Sliding spaces are formed in the right end wall of the air pressure groove in a front-and-back symmetric mode, and the rightend walls of the sliding spaces communicate with the outside space. Roller spaces are formed in the upper end walls of the sliding spaces in a front-and-back symmetric mode. The lightning arrester issimple in structure and convenient to operate, during work, the lighting arrester can be enabled to work when wind in any direction reaches a certain intensity, so that it is ensured that high-voltage cables of which front and rear parts are clamped are prevented from shaking violently, and the connection between the high-voltage cables and the arrester is ensured.

Description

Technical field [0001] The invention relates to the field of lightning protection, in particular to a lightning arrester. Background technique [0002] At present, with the advancement of science and technology, the development of society, and the popular use of transportation tools, people can reach farther places. Energy transmission is gradually being sent to remote areas. The erection of high-voltage cables requires the installation of lightning arresters at the erection point to prevent Lightning damages the power transmission device, but the high-altitude strong wind greatly harms the connection between the arrester and the high-voltage cable. At this stage, the lightning arrester is directly connected to the high-voltage cable, and minor protective measures have been taken, which is not conducive to its protection. Summary of the invention [0003] The purpose of the present invention is to provide a lightning arrester to solve the above-mentioned background art problems. ...

Problems solved by technology

[0002] At present, with the advancement of science and technology, the development of society, and the popularization of transportation, people can reach farther places, and energy transmission is gradually sent to remote areas. When erecting high-voltage cables, lightning arresters must be placed at the erection points to prevent Lightning damages the power transmission device, but the high-altitude strong wind greatly endangers the connection between the arrester and the high-voltage cable. At this stage, the arrester and the high-voltage cable are directly connected, and small protective measures have been taken, which is not conducive to its protection.
