Abstract

La présente invention concerne une pale d'éolienne comprenant une structure porteuse de charge, un corps de coque et un système de protection contre la foudre. La pale d'éolienne s'étend dans une direction longitudinale entre une extrémité base et une extrémité pointe. La structure porteuse de charge est constituée d'un matériau polymère renforcé par fibres et comprend une pluralité de couches de fibres empilées. Les couches de fibres empilées comprennent des fibres électroconductrices, telles que des fibres de carbone. Le système de protection contre la foudre comprend un récepteur de foudre disposé de manière à être librement accessible dans ou sur le corps de coque. Le système de protection contre la foudre comprend un câble de descente de foudre, qui est relié électriquement au récepteur de foudre et est également conçu pour être connecté électriquement à une liaison de terre. La pale d'éolienne comprend en outre un système d’équilibrage de tension, qui fournit une liaison d’équilibrage de tension entre un nombre de fibres électroconductrices de la structure porteuse de charge et le système de protection contre la foudre. Le système d’équilibrage de tension comprend un élément de dissipation en matériau électroconducteur. L'élément de dissipation comprend au moins un connecteur transversal qui est agencé de manière à s'étendre transversalement à travers l'épaisseur des couches de fibres empilées et étant conçu de façon à permettre la dissipation.
