Abstract

En vindturbinrotor med et rotornav (3) og flere blader (4) og hvor hver bladrot (16) er forbundet til rotornavet gjennom et stigningslager (5) på en slik måte at stigningsvinkelen av bladet er justerbar ved å dreie bladet rundt dets langsgående akse i forhold til rotornavet. Bladet er forsynt med minst en elektrisk ledende lynavleder (6) som strekker seg i den langsgående retning av bladet til bladroten og som er elektrisk isolert fra stigningslageret (5). Et gnistgap (15) er tilveiebrakt mellom lynavlederen og rotornavet og gnistgapet (15) er tilpasset for å lede en lynstrøm som passerer gjennom lynavlederen. En glidende kontaktforbindelse (7, 12) er tilveiebrakt parallelt med gnistgapet (15) mellom lynavlederen (6) og rotornavet (3), idet den glidende kontaktforbindelsen sikrer elektrisk kontakt mellom lynavlederen (6) og rotornavet (3) uavhengig av bladets stigningsvinkel. Oppfinnelsen angår også en vindturbin med en slik rotor.
