Contactless sliprings pass tests
The manufacturer of industrial wireless power devices announced the successful trial of the Proxi-Ring 480, a contactless slip ring that provides wireless power and data to pitch-control systems in wind turbines. The Proxi-Ring 480 is said to make wind-energy generation more cost-effective by increasing uptime and reliability and eliminating costs of maintaining and replacing mechanical…
Wind Turbine Reliability – The Importance of Highly Reliable Pitch Control and Blade Sensing Systems
In this 40 minute webinar, learn how two common hazards can hamper a wind turbine’s production. Wind-turbine owners and operators may experience a significant reduction of generated power, reducing overall turbine efficiency, if they don’t take into account: Blade Icing Failed Slip Rings Issues Increased Reliability In this free webinar, we explore how Moog Blade…
Trends in sliprings
Sliprings work in the turbine’s hub where they transmit power and signals from stationary cables in the nacelle to rotating equipment in the hub. A slip-ring assembly is often a graphite or precious metal brush that contacts the outside diameter of a rotating metal ring. As the ring turns, electrical current or signal is conducted…
