Lightning-conductor device for Wind Turbine Generators

摘要

An aluminum cap (2) is installed at the end of each blade of the wind generator and an aluminum profiled section (3) is attached to the longitudinal edge of each blade. A fire protected conductor (4) located parallel to the blade mast is connected by equipotential conductors (6) to the profiled section and lightning discharge currents pass through a cable (9) and slip rings and brushes (12,13) to the tower and earth
