Lightning rod erection method based on number of lightning strokes

Abstract

The invention discloses a lightning rod erection method based on number of lightning strokes, comprising the following steps: erecting a lightning rod at a preset point of a target area; obtaining thelightning stroke data of the lightning rod per hour at the preset point in lightning weather; and adding the lightning rod at the preset point according to the lightning stroke data of the lightningrod per hour at the preset point of N hours. Therefore, by detecting the lightning stroke frequency and strength in lightning stroke of the lightning rod at the preset point for a long time, the lightening stroke condition of the preset point is obtained, so that the proper quantity of lightning rods can be arranged at the preset point, and the possibility that non-lightning rod equipment suffersfrom lighting stroke at the preset point is reduced.

Description

technical field [0001] The invention relates to the technical field of lightning rods, in particular to a lightning rod erection method based on the number of lightning strikes. Background technique [0002] At present, lightning disasters pose a prominent threat to the safe and reliable operation of a large number of wind turbines. Modern wind turbines are generally erected in mountainous areas or other areas with a height of more than 150m, and their exposed fan blades and engine covers are usually made of composite materials. , cannot directly withstand lightning strikes or conduct lightning currents, and it is very easy to cause damage when struck by lightning; secondly, when the lightning current is released from the lightning terminal to the ground through the fan, it may pull the arc and burn the bearing, and the burn marks will be enlarged during the rotation of the bearing It is highlighted and threatens the safe operation of wind turbines; finally, the control syst...
