The 10 MW generators adopts modular concept to the superconducting coil and associated cryogenic systems. And the modular superconducting coil and cryostat of this novel generator will be validated through a scale-down rotating magnetic validator (RMV). The cryogenic cooling system for the RMV consists of two modular cryostats: a distributing cryostat and the corresponding rotating cryocooler system with a self-developed rotary joint. In order to achieve the SC coils’ working temperature of 20 K, a two-stage G–M cryocooler will be applied and linked to the two modular cryostats by way of a conductive copper connection. The distributing cryostat was developed to envelop the cold head of the cryocooler, thermal link, and three binary current leads to electrically feed the coils. A rotary joint with Ferrofluid sealing was developed to transfer the helium gas between the rotating cold head and stationary oil-lubricated compressor. In this paper, the design, manufacture, and assembly of this cryogenic system for RMV will be presented in detail.enginfo:eu-repo/semantics/restrictedAccessjournal article10.1109/TASC.2017.2779499CryogenicsSuperconducting generatorsWind turbineElectronic, Optical and Magnetic MaterialsCondensed Matter PhysicsElectrical and Electronic EngineeringSDG 7 - Affordable and Clean EnergySDG 9 - Industry, Innovation, and Infrastructurehttp://www.scopus.com/inward/record.url?scp=85038386012&partnerID=8YFLogxK
