WIND TURBINE AND METHOD FOR OPERATING A WIND TURBINE WITH TEMPERATURE MONITORING OF THE TRANSFORMER

摘要

The invention relates to a wind turbine having a generator (19) for generating electrical energy and a transformer (20). The transformer (20) is designed to receive electrical energy from the generator (19) on a secondary side (29) and to discharge said electrical energy again on a primary side (28) at a higher voltage. The wind turbine also comprises a temperature monitoring means (26, 27) for the transformer (20). According to the invention the voltage supply to the temperature monitoring means is fed from the primary side (28) of the transformer (20). The temperature monitoring means (26, 27) is thereby independent of the control system (21) of the wind turbine. The temperature monitoring means (26, 27) according to the invention reduces the risk of the transformer (20) overheating. The invention also relates to a method for operating such a wind turbine.
