REpower 6M Offshore Wind Power(6)

Fire protection:

Fully automatic system with active detectors (for smoke and

aerosols) and flue-gas extraction in the nacelle, switchgear

cabinets and transformer room

Automatic nitrogen multi-zone extinguishing system for the electrical components CO2 and ABC fire extinguishers for manual firefighting in the

tower and nacelle

Generator / converter:

Yield-optimized variable speed range Fully enclosed generator with water/air heat exchanger Low converter losses and high overall efficiency due to the restriction of the converter output to max. 20% of the overall output Redundant converter system (reduced operation of up to 66% of the rated output is possible if a converter fails) Frame construction minimizes the oscillations and vibrations

Transformer:

Cast resin dry-type transformer with very high environmental compatibility Reduced mass and low fire risk Fully enclosed installation with air/air heat exchanger Selectable output voltages with 20, 30 and 33 kV
