Abstract

A lightning protection apparatus used for an overhead line comprises: a bough lightning protection needle vertically mounted at the top end of an overhead line steel tower, and at least one branch lightning protection needle layer arranged at intervals along a needle body of the bough lightning protection needle from top to button, wherein each branch lightning protection needle layer comprises a plurality of branch protection needles, and each branch lightning protection needle is at an included angle of smaller than 90 degrees with the bough lightning protection needle to extend diagonally and upwards. According to the lightning protection apparatus, a lightning protection way of conducting lightning to the apparatus is fundamentally changed; the risk of lightning stroke can be effectively reduced; and the apparatus is simple in structure, low in cost, does not need to be grounded, and is easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of lightning protection of high voltage technology, in particular to a lightning protection device for overhead lines. Background technique [0002] The traditional lightning rod is installed at the highest point of a building or other protected object. When lightning occurs, this highest point and the thundercloud form an extremely unevenly distributed electric field environment, which makes the air between the thundercloud and the lightning rod very easy to be struck. Through the lightning rod, the lightning current can easily discharge the lightning energy to the earth through the lightning rod. In fact, this lightning protection method that discharges lightning energy by guiding the lightning itself is more likely to cause direct lightning strikes, especially for overhead lines erected in the field. It is difficult to achieve the ideal effect, and it is very easy to cause a counterattack to the overhead ...
