Slip rings for wind turbine generators

What is a wind turbine slip ring?

So a wind turbine slip ring can be provided with a single contact material that will handle high power as well as data communication channels. The primary advantage of the fiber brush design is that 100 million revolutions can be achieved in wind turbine blade pitch applications with no maintenance.

Do wind turbine slip rings cause arcing?

Historically wind turbine slip rings have been constructed with carbon-based brushes using standard industrial grade materials, and wear debris generation has been a problem causing arcing or short circuits in the power section and high contact noise in the signal section.

What are the applications of rotor de-icing slip rings?

Three notable applications have been helicopter rotor de-icing slip rings, radar pedestal slip rings, and wind turbine slip rings. Each of these applications requires long life, high conductivity for high power transfer, and operation in very dificult environments.

What are rotarx slip rings?

Within the wind turbines, the slip rings are assigned a wide variety of safety-relevant tasks which have a major influence on the availability and efficiency of the machines. rotarX slip rings are therefore specially designed for such applications and can offer corresponding differences, particularly in the areas of performance and quality.

How does a wind turbine rotor work?

Most modern wind turbines require electrical power and signals to be delivered to the blades for blade pitch actuation. A number of sensors can also be resident on the rotor that require delivery of electrical power to the sensors and signal transission from the sensors to the controller.

What is a Moog slip ring?

Moog slip rings are components that provide performance and quality in demanding environments. They use fiber brushes and robust mechanical components in their design to eliminate costly downtime.
