Title:
OFFSHORE DOUBLY-FED GENERATOR SLIP RING COOLING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/066375
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of doubly-fed generator slip ring systems, and provides an offshore doubly-fed generator slip ring cooling system and method. The system comprises: a slip ring component; a slip ring box; a cooling fan; a valve; and a filtration system comprising a rainwater separator, primary-efficiency filter cotton, and medium/high-efficiency filter cotton. According to the present invention, the reliability of an offshore doubly-fed generator slip ring system can be effectively improved, and a foundation is laid for offshore application of a doubly-fed generator; slip ring cooling is decoupled from compartment cooling in the present invention, mutual influence is avoided, and the protection performance of other components in a compartment is guaranteed; moreover, when the system of the present invention stops running, a surface of a slip ring is not prone to condensation due to air intake and output protection, so that the surface of the slip ring is not prone to being corroded, and the reliability of re-operation of the system is guaranteed; in addition, a carbon powder collection device of the present invention is simple and can meet a flame-retardant requirement, and has a relatively long service life.
