ABSTRACT:
The invention relates to a wind turbine (1) comprising stationary means such as a nacelle (3) and a tower (2) comprising stationary lightning protection means (46), and rotating means such as a rotor including at least one wind turbine blade (5) and shaft means (14), each of said at least one wind turbine blade (5) comprising rotating lightning protection means (47). The stationary and rotating lightning protection means (46, 47) comprise contact surfaces (17, 18) connected by lightning connection means (15). The lightning connection means (15) comprises at least two contact means (19, 19a, 19b) adapted for connecting said rotating and stationary lightning protection means (46, 47). Further, it comprises at least one electric conductor (30) establishing a dedicated connection between said at least two contact means (19, 19a, 19b) and force transferring means (26, 27) for said at least two contact means (19, 19a, 19b) establishing a continuous connection between said at least two contact means (19, 19a, 19b) and the contact surfaces (17, 18) of said stationary and rotating lightning protection means (46, 47). The invention also relates to lightning connection means (15) for a wind turbine (1), a method and use hereof.
