Abstract[English]
A wind turbine (W) has a hub (2) rotatably supported relative to a nacelle (3) and plurality of blades (1) mounted on the hub (2). A lightning current transfer system (100) is arranged to provide a lightning current transfer path (P) from at least one of the blades (1) to the nacelle (3). The lightning current transfer system (100) has at least one electrical conductor (20) which passes through a hollow interior portion of the hub (2) between the at least one of the plurality of blades (1) and the nacelle (3). A cover (24) is provided for attenuating an electromagnetic field generated by a lightning current in the electrical conductor (20) passing within the hollow interior portion of the hub.[French]
L'invention concerne une éolienne (W) qui comprend un moyeu (2) supporté de manière rotative par rapport à une nacelle (3) et une pluralité de pales (1) montées sur le moyeu (2). Un système de transfert de courant de foudre (100) est agencé pour fournir un trajet de transfert de courant de foudre (P) de l'au moins l'une des pales (1) à la nacelle (3). Le système de transfert de courant de foudre (100) comporte au moins un conducteur électrique (20) qui passe à travers une partie interne creuse du moyeu (2) entre la ou les pales de la pluralité de pales (1) et la nacelle (3). Un couvercle (24) est disposé pour atténuer un champ électromagnétique généré par un courant de foudre dans le conducteur électrique (20) passant à l'intérieur de la partie interne creuse du moyeu.
