Abstract

L'invention concerne un système de générateur d'éolienne destiné à des environnements à température élevée comprenant une filasse (1), un mécanisme principal (2) installé au sommet de la tour, et un rotor (3) relié au mécanisme principal. Un inverseur (4) et une cabine de commande à la base de la tour (7) sont disposés de façon interne en bas de la tour. Un réducteur d'augmentation de vitesse (5) relié au rotor est disposé au niveau de l'extrémité avant du mécanisme principal, et un générateur électrique (6) est relié à l'arbre de sortie du réducteur d'augmentation de vitesse. Une cabine de commande de nacelle (8) est disposée dans la partie du milieu du mécanisme principal, et un ventilateur à flux axial (9) pouvant extraire la chaleur de l'intérieur du mécanisme principal est disposé dans la partie postérieure de celui-ci. Le système de générateur d'éolienne est un système générateur à grande échelle, spécialement applicable dans des environnements à température extrêmement élevée. Le système de générateur d'éolienne peut normalement produire de l'électricité à des températures allant de -30 °C à +50 °C.
