What are wind turbine sliprings?

These devices allow transmitting power and signals from a stationary platform to one that is rotating. 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, an electrical current or signal conducts through the stationary brush to the metal ring

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

This slipring does not slip

Industrial designers, engineers, and manufacturers in industries that employ machinery with rotating parts such as wind turbines and radar now have a new way to avoid critical downtime that occurs from failed electrical and mechanical connectors. Mechanical slip rings, through-hole slip rings, and high-current slip rings often limit designers’ and manufacturers’ ability to power systems

Contactless slip rings transmit power and data

Wireless sliprings from PowerbyProxi are based on inductively coupled power transfer technology. Inductive-power transfer applies the scientific principle of electromagnetic inductance. The patented Proxi-Wave lets these sliprings achieve high efficiencies by using wireless power transfer that can harmonize itself in the field. This makes the systems resistant to changes in realworld environmental conditions and load

Slip rings handle up to 60 A

Electrical slip rings are ready to handle a variety of industrial applications up to 60 A and 5 MW. The electrical devices allow transmitting power and electrical signals from a stationary to a rotating structure. The devices configure easily for power or signal connections. The signal portion of the slip rings is compatible with Ethernet,

China’s Sewind buys 400 pitch-control systems from Moog

Moog Industrial Group will provide 400 electric pitch-control systems for China-based Sewind Co. Ltd’s 2-MW wind turbines. The controls will go into on-shore and intertidal models. Sewind Co., one of the top five companies in China’s wind-energy industry, specializes in the design, manufacturing, and sale of large units. Pitch systems control blade positions on wind-turbine

Carbon brushes and holders ready for work

The Current Transmission business unit at Schunk Graphite Technology, Booth 10342, produces flexible power connections and holders for manufacturers of wind turbine electrical equipment and transformer substations. Among that equipment are brush yokes and carbon brushes, their holders, flexible current connections, brush rockers, and more.    Carbon brushes have a high percent of metal to

Slip rings ready for demanding apps

Slip rings for a wide variety of industrial applications come from Deublin Co., Waukegan, Ill. The devices are easily configured for both power connections and signal connections. The signal portion of the slip rings is compatible with Ethernet, Profinet, RS-232, RS-485, RS-422, CAN as well as generic analog or digital sensing and 24V control signals.
