Title:
OPTICAL-COUPLING NON-CONTACT COMMUNICATION SLIP RING FOR WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2022/206656
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communication slip rings. An optical-coupling non-contact communication slip ring for a wind turbine comprises: a slip ring stator, having a first optical communication apparatus; and a slip ring rotor, configured to be rotatable relative to the slip ring stator, the slip ring rotor having a second optical communication apparatus, wherein the first optical communication apparatus and the second communication apparatus are configured to be capable of wirelessly communicating with each other without contact. The present invention uses a non-contact technical solution and solves the problem of contact failure in contact slip rings. Optical coupling has a lower cost than other coupling modes; in addition, the optical-coupling non-contact communication slip ring can still work normally when a failure occurs in part of a coupling device, and thus has a high reliability.
