AI Technical Summary
Existing Schleifring transfer systems face significant size and weight increases when handling higher voltages above 35 kV, due to increased insulation requirements, which is particularly problematic in explosive areas like FPSO ships and offshore wind turbines.
A lob-ring transfer system with a housing containing at least one rotating grinding ring and a contact carrier with contacts that press against the dynamically moving grinding ring, utilizing insulators made of fiber-reinforced plastic without metallic components, and an insulating fluid to reduce the size and weight of the system while maintaining high voltage transmission capabilities.
The solution enables the transmission of higher voltages without increasing the size of the Schleifring transfer system, achieving partial load freedom in both static and dynamic conditions, and is particularly advantageous in explosive areas where compactness is critical.
