How to install lightning rod for rural civil buildings?
Do foundation, installation of grounding structure construction by structure steel (or special steel) do deflectors, and grounding connection, and set aside the connection point and lightning with the completion of the renovation; at the same time, the laying of lightning belt (or rod).
There should be ten meters long and ten meters into the reinforced iron anvil deep underground is effective, can be used as conductive material of lightning rod
In a thunderstorm, building over charged clouds, lightning and are at the top of the tall building on a large number of induction charge, due to lightning needle is pointed, so the electrostatic induction, the tip conductor always gathered the most charge. In this way, the lightning rod gathers most of the charge. The lightning rod also forms a capacitor with these charged clouds. Because of its sharp tip, the two plate of the capacitor is facing a small area, and the capacitance is very small, that is to say, it can hold very little charge. And it brings together most of the charge, so when there is more charge on the clouds, the air between the lightning rod and the cloud is easily broken down and become a conductor. Thus, the electrified cloud layer forms a passage with the lightning rod, and the lightning rod is grounded, and the lightning rod can lead the charge on the cloud to the ground, so that it does not pose a danger to the high-rise building and ensures its safety.
When installing, grounding electrodes are installed:When the structure is constructed, the reinforcing bar (or special steel) is used as the lead out line to connect with the grounding electrode, and the connecting point of the lightning rod is reserved;When the decoration is finished, the lightning belt (or lightning rod) shall be laid.
