Study on Design of 35kV Class Transformers Built Inside Wind Turbine Towers
The 35kV class transformers built inside wind turbine towers can be divided in-to two types:tower transformers and nacelle transformers.Based on the characteristics of wind turbines,this paper compares and analyzes the advantages and disadvantages of tower transformers and nacelle transformers.Design considerations are proposed from various aspects such as load impact resistance,overvoltage resistance,heat dissipation,reliability under cooling failure,and vibration resistance,aiming to enhance the opera-tional reliability of transformers.
