| 摘要 |
The invention relates to a wind turbine comprising a nacelle (104) and a rotor having at least two rotor blades (108). Each rotor blade (108) comprises a rotor blade root (108a), at least one metal conductor (220) for conducting a lightning strike, and a conductive ring (230) connected to said metal conductor and provided in the root region of the rotor blade. In addition, a lightning protection unit (240) is fixed on the non-rotating part of the nacelle (104) in such a way that the lightning protection unit (240) is supported on the ring (230). The lightning protection unit (240) comprises two rollers (241) and a lightning rod (242), a free end of said lightning rod (242) being at a distance from an outer end of the roller (241) and said distance defining a spark gap. |
