Lightning rod, also known as lightning rod and lightning rod, is a device used to protect buildings, tall trees and so on from lightning. Install lightning arrester on the top of the protected object, and connect it with the underground drainage network with wires that meet the specifications. The specifications of lightning rods must meet the national standards, and the height specifications of lightning rods required by each lightning protection category are different.
When Lei Yun discharge approaches the ground, it will distort the ground electric field. A space with concentrated local electric field is formed at the top of the lightning rod, thus affecting the development direction of lightning pilot discharge, guiding lightning to discharge to the lightning rod, and then introducing lightning current into the earth through the grounding down lead and grounding device, thus preventing the protected object from being struck by lightning.
