The outdoor air conditioner is close to the lead of the lightning rod
Because of the lightning current changes will generate an alternating magnetic field gradient is very large and powerful, the metal components around the induced current, this current may discharge to the surrounding objects, such as near combustible materials will cause fire and explosion, and the induction to the conductor are online on will bring destructive strong to the equipment, the equipment damage. The measures should be based on the specific circumstances of various equipment, in addition to the grounding and wiring system, the safe distance, but also by the power supply line, power line and signal line, communication line, feeder installation corresponding arrester and shielding measures.
The lightning rod mainly prevents direct lightning, and protects the building from being struck by lightning, so that the protected object is in the lightning protection area. The main reason for the damage caused by lightning is that 90% is mainly caused by induced lightning, also known as the two damage. It is divided into two kinds of electrostatic induction thunder and electromagnetic induction lightning.
The nearer the air conditioner is to the top of the lightning rod, the higher the probability of lightning strikes. Generally more than 2 meters distance, relatively safe, can also extend the lightning rod, reducing the probability.
