要約
(EN)
The invention provides a wind turbine generating apparatus capable of controlling a temperature in a rotor head. In a wind turbine generating apparatus (1) in which a driving/generating mechanism coupled to a rotor head (4) having wind turbine blades (5) attached thereto is housed in a nacelle (3), and control devices are housed in a hub (7) of the rotor head (4), an air circulation guide (20) is provided for allowing air to circulate between an inside of the rotor head (4) and an inside of the nacelle (3) via a communication path (9) formed between the rotor head (4) and the nacelle (3).

(FR)
L'invention a pour objet un générateur électrique éolien (1) dans lequel la température à l'intérieur d'une tête de rotor peut être contrôlée. Une turbine éolienne (5) est montée sur la tête du rotor (4). Un mécanisme d'entraînement et de génération électrique est reçu dans la nacelle (3) et connecté à la tête du rotor (4). Des dispositifs de contrôle sont reçus dans un moyeu (7) de la tête du rotor (4). Le générateur (1) a un guide de circulation d'air (20) permettant de faire circuler l'air entre l'intérieur de la tête du rotor (4) et l'intérieur de la nacelle (3) par le biais d'une voie de transmission (9) formée entre la tête du rotor (4) et la nacelle (3).
