Lightning conduction system for wind turbine blades with carbon fibre laminates

摘要

Lightning rod system for wind turbine blades formed by various connections set up on carbon fiber laminates (2) on the blade (1), equipotentializing the surface of the flanges (4) of the beam (10) through the deviations of a primary cable (6) with the respective auxiliary cables (5), carried out with the use of a device (12) whose terminals are connected between the ends of the cited auxiliary cable (5). The use, given the elevated inductance of device (12) mounted on the connection between the carbon laminates (2) and the conductor cable or primary cable (6), is to reduce the passage of current across the carbon laminate and favor the conduction through the metal cable.
