How can the protection range of single lightning rod be calculated?
The ground lead wire is the middle part of the lightning rod, which is used to connect the lightning receiver and the grounding body. The cross sectional area of the grounding wire shall be calculated not only according to the heating conditions during the passing of the lightning current, but also not to be melted due to excessive heat, and also to have enough mechanical strength. The grounding body is the lowest part of the whole lightning rod. Its role is not only to safely transmit lightning current into the ground, but to further scatter the lightning current into the ground evenly. The working principle of the lightning rod is, in essence, that the lightning rod is not a lightning rod, but uses its high position in the air to direct the lightning to itself and bear the lightning stroke. At the same time, lightning currents are released into the earth to protect them from nearby buildings or equipment that are protected from lightning. The lightning rod protects it near its shorter buildings or equipment against lightning.
It is well known that thunder is a common natural phenomenon. Lightning strikes a strong destructive effect. Lightning protection is an important subject for human struggle against nature. The installation of lightning rod is one of the effective lightning protection measures. The lightning rod is composed of three parts of a receiver, a grounding lead wire and a grounding body (grounding electrode). The receiver of a lightning rod is the metal needle at the top of the lightning rod. The receiver is positioned above the protected object
A new method of determining single lightningrods protection range, will protect the scope of lightning rod for safe lightning range and safety protection range of the 2 part. When the safe protective range of the object to be protected in the lightning, lightning fell within the safe range of the lightning arresters will hit. The method of determining the lightning protection scope clear, no surround thunder struck. Protection range of single lightning rod
