Does the wind pack the lightning rod?
Can be installed, but lightning simply for the lightning protection effect of fan and the poor, this is because the fan being struck by lightning during high-speed operation, by a lightning rod can not do within a short time after this may cause loss of shunt, the fan.
According to the IEC62305-1 standard, with wind turbines protected from lightning frequency and the expected years allowed to fall according to the number of flash, determine the protection level of wind turbine, to determine the protective equipment and the corresponding.
Wind turbines are installed in the vast plains of the field, and wind power generation equipment up to tens of meters or even hundreds of meters, resulting in extremely easy to be struck by lightning, and become a lightning flash directly. As the internal structure of the fan is very compact, whether the blade, cabin or tail is struck by lightning, the electronic control system in the cabin may be attacked by the high potential of the engine room. In the power and control loop along the tower down the way, may also be subjected to high potential counterattack. As a matter of fact, for a tall object in the wilderness, no matter how protective it is, it is impossible to completely avoid lightning stroke. Therefore, for lightning protection of wind turbine, the focus should be on how rapidly the lightning lightning current into the earth, as far as possible to reduce the electricity into the equipment, to maximize the protection of the safety of equipment and personnel, to reduce the damage to a minimum degree.
Therefore, from the point of view of lightning protection, the wind turbines should be equipped with a whole set of grounding devices for all grounding (such as lightning protection, electrical systems, communication systems). A base device that must be installed separately for other reasons shall be connected by equipotential connection to a common grounding device. So as to achieve the effect of lightning protection.
