Title:
CONDUCTIVE RING ASSEMBLY, CONDUCTIVE DEVICE AND WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2018/103285
Kind Code:
A1
Abstract:
Disclosed are a conductive ring assembly (100), a conductive device and a wind turbine. The conductive ring assembly (100) comprises a sun gear (30), a ring gear (10) and one or more planet gear (20). The sun gear (30) is located in the ring gear (10), and the sun gear (30) and the ring gear (10) are coaxially arranged. The one or more planet gear (20) is engaged between the sun gear (30) and the ring gear (10). The planet gear (20) is conducted with the sun gear (30) and the ring gear (10) at the same time, so that an electrical signal is transmitted between the sun gear (30) and the ring gear (10) by means of the one or more planet gear (20). The conductive ring assembly (100) uses a planet gear structure for communication data transmission to improve the interference resistance of the conductive ring assembly (100), so that the capability of same in coping with rotational speed jitter is improved, and the abrasion of a communication line is reduced at the same time, thereby improving the stability and reliability of communication of a slip ring.
