Title
(EN) A BLADE FOR A ROTOR OF A WIND TURBINE COMPRISING INTERNALLY A CONTINOUS CABLE ARRANGEMENT INTENDED TO MEASURE CONDUCTIVITY
(FR) PALE DESTINÉE À UN ROTOR D'UNE ÉOLIENNE ET COMPRENANT INTÉRIEUREMENT UN AGENCEMENT DE CÂBLE CONTINU DESTINÉ À MESURER LA CONDUCTIVITÉ
Abstract
(EN) Blade (1) comprising inwardly a continuous cable arrangement (2) intended to measure conductivity for blade lightning protection, wherein the cable arrangement (2) comprises an upper portion (4) and a lower portion (3) extending therebetween the blade root (8) and the blade tip (9), said lower portion (3) electrically in contact with the upper portion (2) closing an electrical loop, and wherein the blade (1) further comprises an electrical connector element (7) located at the blade root (8) and electrically in contact with the upper portion (3) and the lower portion (3), said electrical connector element (7) protruding exteriorly on the blade root (8) so that conductivity of the blade (1) can be measured.
(FR) L'invention concerne une pale (1) comprenant intérieurement un agencement de câble continu (2) destiné à mesurer la conductivité pour la protection contre la foudre de la pale. L'agencement de câble (2) comprend une partie supérieure (4) et une partie inférieure (3) s'étendant entre la racine de la pale (8) et la pointe de la pale (9), ladite partie inférieure (3) en contact électrique avec la partie supérieure (2) fermant une boucle électrique, et la pale (1) comprend en outre un élément de connecteur électrique (7) situé au niveau de la racine de la pale (8) et en contact électrique avec la partie supérieure (3) et la partie inférieure (3), ledit élément de connecteur électrique (7) faisant saillie à l'extérieur sur la racine de pale (8) de telle sorte que la conductivité de la pale (1) puisse être mesurée.
