WIND POWER GENERATOR

摘要

A wind power generator capable of temperature control inside a rotor head. The wind power generator (1) has a driving and power-generating mechanism coupled with a rotor head (4) having a vane (5) attached there on, which is accommodated in a nacelle (3), and machines installed in the rotor head (4). A rotary joint (30) is interposed on a driving shaft coupling between the rotor head (4) and the nacelle (3), and a fluid for adjusting the temperature in the rotor head is supplied from the inside of the nacelle (3) through the rotary joint (30) into the rotor head (4). ® KIPO & WIPO 2009
