Document Type and Number:
WIPO Patent Application WO/2023/066376
Kind Code:
A1
Abstract:
The present invention relates to the technical field of doubly-fed generator slip ring systems, and provides a closed offshore doubly-fed generator slip ring cooling system and method. The system comprises: a slip ring component; a slip ring box, which is configured to accommodate the slip ring component and to isolate the slip ring component from air in a cabin of an offshore doubly-fed generator, wherein the slip ring box has a closed air path, which does not communicate with the outside; a filtering system, which is arranged in the closed air path to perform filtering and heat-exchange cooling on the air; a radiator, which is arranged in the closed air path behind the filtering system so as to perform heat-exchange cooling on the filtered air; and a cooling fan, which is arranged in the closed air path to enable the air to sequentially flow through the filtering system, the radiator and the slip ring component, wherein the air flows through the slip ring component to clean foreign particles generated by operation of the slip ring component.
