1. Vindmøllerotor omfattende et rotomav (3) og et antal vinger (4), hvor hver vinge-rodende (16) via et pitchleje (5) er forbundet med rotomavet, så at vingens pitchvinkel kan indstilles ved at dreje vingen omkring sin længdeakse i forhold til rotomavet, og hvor vingen er forsynet med mindst en elektrisk ledende lynnedleder (6), som forløber i vingens længderetning til vingerodenden, og som er elektrisk isoleret fra pitchlejet (5), og hvor der mellem lynnedlederen og rotomavet er tilvejebragt et gnistgab (15), der er indrettet til at kunne lede en lynstrøm, som løber gennem lynnedlederen, kendetegnet ved, at der parallelt med gnistgabet (15) mellem lynnedlederen (6) og rotomavet (3) er tilvejebragt en slæbekontakt-forbindelse (7,12), der sikrer elektrisk kontakt mellem lynnedlederen (6) og rotomavet (3) uanset vingens pitchvinkel. 2. Vindmøllerotor ifølge krav 1,kendetegnet ved, at slæbekontaktforbindel-sen omfatter en slæbesko (12), der er fast monteret på rotomavet (3), og et elektrisk ledende kontaktelement (7), der er forbundet med vingens lynnedleder (6) og strækker sig langs en del af vingerodendens (16) omkreds. 3. Vindmøllerotor ifølge krav 1,kendetegnet ved, at slæbekontaktforbindel-sen omfatter en slæbesko (12), der er fast monteret på vingerodenden (16), og et elektrisk ledende kontaktelement (7) i form af en skinne, der er monteret på rotomavet (3). 4. Vindmøllerotor ifølge krav 2 eller 3,kendetegnet ved, at gnistgabet (15) er tilvejebragt mellem kontaktelementet (7) og et gnistgabselement (11). 5. Vindmøllerotor ifølge krav 4, kendetegnet ved, at slæbeskoen (12) og gnistgabselementet (11) er bygget sammen i en kontaktenhed (8). 6. Vindmøllerotor ifølge et af de foregående krav, kendetegnet ved, at lyn-nedlederen (6) er forbundet med en lynreceptor nær vingens tip. 7. Vindmølle omfattende en vindmøllerotor ifølge et af de foregående krav.
