gerador de turbina eólica.

摘要

A wind turbine generator according to the present invention includes: a rotor head equipped with wind turbine blades to constitute a wind turbine rotor blade; a nacelle that bears a rotation shaft of the rotor head and houses a generator that generates electricity by a rotation of the rotor head; a tower that supports the nacelle; a rotor head cover that covers the rotor head; an outside-air intake that is provided on a distal end part of the rotor head cover and takes in the outside wind; an outside-air delivery communicating parts that delivers the outside air, which has been taken into the rotor head cover from the outside-air intake, to an inside of the nacelle; and cooling air outlets that are provided in a region of the outer surface of the nacelle that experiences a negative pressure due to the outside wind.
