Zusammenfassung:	A wind turbine is provided, having a nacelle, and having a rotor that has at least two rotor blades. The rotor blades each have a rotor blade root, at least one metallic conductor, for conducting a lightning strike, and connected thereto, provided in the region of a rotor blade root, have a conducting ring. In addition, a lightning protection unit is fastened to the non-rotating part of the nacelle in such a manner that the lightning protection unit lies on the ring. The lightning protection unit has two rollers and a lightning rod, a free end of the lightning rod being separated from an outer end of the rollers by a distance that defines a spark gap.
