Estimating the term…
A slip ring apparatus, a yaw system, and a wind turbine generator set are provided. The slip ring apparatus includes 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.
A slip ring device, comprising a rotating part and a fixed part, wherein the rotating part is configured to rotate relative to the fixed part, a conductive ring is arranged on the rotating part, and a brush is arranged on the fixed part, and an inclined slot is provided on at least one of the conductive ring and the brush, and when the conductive ring and the brush are in contact, the inclined slot is allowed to discharge the wear debris generated as the conductive ring and the brush are in contact.
