Wind Turbine Generator Slip Ring

slipring is just a small part in the industrial production and manufacturing, the slip ring plays a very significant role in the operation. The slip ring usually is installed in the engine hood fan and used for providing a variable propeller power and control the electrical signal & power, so slip ring could transmit power and signal through a rotating interface.

The slip ring working principle: the contact materials of slip ring through rotating connections to transfer electrical signal and energy, brush or contacting brush slide on the rotating slip ring and keep continuous contact during operation. That is to say, in order to ensure the correct electrical signal transmission, also the static brush between brush block need to have precious metal contacting materials.
