The nacelle of a wind turbine rotates with the wind direction; a conductive slip ring is used to stably transmit the electrical energy generated by the nacelle to the fixed power grid at the base of the tower.
Dynamic contact technology: To address the characteristics of high vibration and low rotational speed in wind turbines, the latest solution employs a pneumatic dynamic contact system.
Ultra-high power transmission: For high-power applications such as offshore wind power, slip rings featuring extra-large-diameter copper strips are used. These utilize a segmented copper-strip winding process, offering extremely high current-carrying capacity and ensuring stable operation and signal integrity during high-current transmission.
It primarily addresses the issue of dynamic electrical power and signal transmission between rotating and stationary components.
Conductivity: Contact materials typically include silver-based alloys, copper-graphite, or conductive polymers to balance electrical conductivity with wear resistance.
Multi-channel Transmission: Modern slip rings often feature multi-channel designs, integrating power transmission, sensor signals, and Ethernet data transfer into a single unit without mutual interference.
Protection Rating: For outdoor applications, a high protection rating (such as IP65) is required to prevent erosion caused by wind-blown sand, salt spray, and moisture.
