Slip Rings

Power Slip Rings for Wind Generators

Power slip rings for wind generators — transmit power & signal across rotating hub/nacelle: DFIG excitation class (200–1,500 A/ring), pitch power tracks (80 A/phase @ 400/690 VAC, silver braid brushes), small-turbine class. Maintenance-free, >100M-rev life, IP54–67. Verify current, circuits & turbine model.

Description

Overview

Power slip rings for wind generators — the rotating power-transfer interface of wind turbines: carry high power plus control/data signals from the rotating hub/nacelle to the stationary tower, for DFIG generators, pitch control and small turbines.ByTune

Duty Classes

DFIG generator: 200–1,500 A per ring (excitation rings)
Pitch control: up to 80 A per phase @ 400/690 VAC (silver braid brushes on silver rings); Conductix PCS-class 65–100 A @ 600 V
Small turbines: 5–30 A yaw/power

Reliability

Brush/ring life > 100 million revolutions; no lubrication, no maintenance (PCS-class)
Noble-metal fiber brush: low contact force, very low wear, high current density (Moog)
IP54–IP67, C4/C5 anti-corrosion, −40 to +80 °C
Signal: CAN, Profibus, Ethernet, fiber-optic
