摘要： A wind turbine blade having a lightning protection function includes an outer shell, a spar arranged in a space inside the outer shell, a spar cap which is formed by a carbon-fiber plastic laminated member disposed on a blade root side and a glass-fiber plastic laminated member disposed on a blade tip side that are connected together, the spar cap supporting the spar to the outer shell, and a lightning protection unit. The lightning protection unit includes a receptor for receiving lightning which is provided in the outer shell on a side where the glass-fiber plastic laminated member is arranged, a down conductor which directs lightning current received by the receptor into the ground or the water, and a conductive metal member which covers the outer shell on a side where the carbon fiber plastic laminated member is arranged.

摘要： The invention relates to a wind turbine blade for a wind turbine, having a tip end area, a tip end and a root end area and a lightning protection system. The lightning protection system comprises at least one metal foil, wherein said metal foil extends continuously from a first end in the tip end area towards the root end area of the blade and wherein the metal foil is arranged in proximity to the outer surface of the blade, so that the metal foil is adapted to function as a receptor of a stroke of lightning and as a down conductor. The lightning protection system further comprises a first metallic lightning receptor being in direct electrical contact with the metal foil, wherein the first metallic lightning receptor is disposed in proximity to the outer surface of the blade and between the first end of the metal foil and the blade tip end.
