Title (EN) WIND TURBINE LIGHTNING PROTECTION AND MONITORING SYSTEMS
(FR) ELÉMENT DE PROTECTION CONTRE LA FOUDRE D'UNE ÉOLIENNE ET SYSTÈMES DE SURVEILLANCE
Abstract:
(EN) A wind turbine hub (8) and nacelle (4) assembly including lightning conducting means (26, 30, 32, 40) for conducting lightning between the hub (8) and the nacelle (4), the hub (8) being mounted for rotation relative to the nacelle (4) and being adapted to support turbine blades, the hub (8) including a hub conductor (26) for connection to a turbine blade supported by the hub (8), the lightning conducting means including a conductive track (40) and a terminal (30, 32) which confront and are displaceable relative to each other, one of the conductive track (40) and the terminal (30, 32) being mounted on the hub (8) and being electrically connected to the hub conductor (26) and the other of the conductive track (40) and the terminal (30, 32) being mounted on the nacelle (4), the terminal (30, 32) including a terminal main body (30) which is spaced from the conductive track (40) and a sacrificial conductive terminal extension (32) extending from the terminal main body (30) towards the track (40).
(FR) L'invention concerne un moyeu d'éolienne (8) et un ensemble nacelle (4) comprenant un élément de raccord parafoudre (26, 30, 32, 40) pour guider la foudre entre le moyeu (8) et la nacelle (4), le moyeu (8) étant fixé pour rotation par rapport à la nacelle (4) et étant conçu pour supporter les pales de turbine, le moyeu (8) comprenant un conducteur de moyeu (26) en vue d'un raccordement à une pale de turbine supportée par le moyeu (8), l'élément de protection contre la foudre comprenant une piste conductrice (40) et un terminal (30, 32) qui se font face et se déplacent l'un par rapport à l'autre, l'une des pistes conductrices (40) et le terminal (30, 32) étant fixés sur le moyeu (8) et étant électriquement connectés au conducteur de moyeu (26) et l'autre piste conductrice (40) et le terminal (30, 32) étant fixés sur la nacelle (4), le terminal (30, 32) comprenant un corps principal de terminal (30) qui est espacé de la piste conductrice (40) et une extension terminale conductrice sacrificielle (32) s'étendant depuis le corps principal de terminal (30) vers la piste (40).
