Lightning rods, also known as lightning rods, are devices used to protect buildings, tall trees, etc. from lightning strikes. Install a lightning receptor on the top of the protected object and connect it to the underground grounding net with a wire that meets the specifications. The lightning rod specifications must comply with the GB standard, and the lightning rod height specifications required for each lightning protection category are different.
It distorts the ground electric field when the thundercloud discharges close to the ground. At the top of the lightning rod, a space for local electric field concentration is formed to influence the development direction of the lightning pilot discharge, guide the lightning discharge to the lightning rod, and then introduce the lightning current into the earth through the grounding down conductor and the grounding device, thereby protecting the protected object from lightning strikes. .
