Can lightning rod be 100% lightning protection?
It has a relationship with the needle material, there is one line grounding; general needle is made of stainless steel, and with your installation angle and height position determines the lightning protection effect, generally does not appear to limit what problem
Stainless steel lightning rod, lightning conductor, also known as lightning protection needle, is used to protect buildings and other devices to avoid lightning strikes. The installation of a metal bar on top of tall buildings, with a metal line and buried together on a metal plate underground, using metal rod tip discharge, so that the clouds with the electricity and the electric gradually and thus does not cause the accident. Lightning rod specifications must comply with the GB standard, each level of lightning protection required lightning rod specifications are different.
During a thunderstorm, must stay away from a tip of the building, to ensure the safety of human reason] [for example, this is why thunderstorm cannot hide in the tree below you can see the question: general lightning arresters are built in the place of high current high voltage power supply [together] a family is not needed, building construction you can see a circle to the roof, roof steel structure building lightning protection network, what this ring and the lightning rod lightning protection network purpose is the same, but also to the structure when it rains, the lightning current into the earth so that the safety in the rain or the power switch to cut off home as well, under normal circumstances, it is not necessary to worry about.
The purpose of lightning is actually a device based on the principle of the lightning discharge, is said to attract large current into the earth [] zero potential to avoid lightning in buildings, so as to protect an electrical device. 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, and the electrostatic induction, the tip conductor always gathered the most charge. So, the lightning rod gathered the most charge. Lightning rod and the charged cloud formation a capacitor, since it is pointed that the capacitor two is on the plate area is very small, the capacitance is also very small, that is to say it can hold less charge. But it also gathered most of the charge, so when the charge is large, easily between the lightning rod and the air breakdown, become a conductor. In this way, the charged clouds and lightning formation pathways, and lightning and grounding lightning. You can put the charge on the earth by the clouds, the top right The building is dangerous and guarantees its safety
