More Information
Summary:The present invention provides a slip ring apparatus, a yaw system, and a wind turbine generator set. The slip ring apparatus comprises a rotating part and a fixed part, the rotating part can rotate relative to the fixed part, a conductive ring is provided on the rotating part, an electric brush is provided on the fixed part, and a chute is formed in at least one of the conductive ring and the electric brush, so that when the conductive ring and the electric brush are in contact, the chute can discharge abrasive dust generated when the conductive ring and the brush are in contact, thereby suppressing the increase of fretting contact resistance between the conductive ring and the electric brush.
