PROBLEM TO BE SOLVED: To reduce a wear volume of a brush with being adapted to an extensive installation site by canceling humidity influences to be exerted upon a wear speed of the brush even when the conditions of the external environment are different depending on an installation site and the season.SOLUTION: In a wind power generator, a nacelle is located on an upper portion of a support rod, and a rotor head having wind turbine blades fitted thereto is rotatably supported to a front end side of the nacelle. A main shaft rotating integrally with the rotor head, a gear box coupled with the main shaft which rotates while the wind turbine blades receive a wind power, a power generator having a rotor driven by a shaft output of the gear box, a brush, and a slip ring, and a humidity management device controlling humidity inside of the power generator having the brush and the slip ring, are installed in an interior of the nacelle. |
