YFF005 1.65MW Water-cooling Double-fed
Type YFF005 1.65MW Water-cooling Double-fed Asynchronous Wind-driven Generator
Main technical features¡¡
It adopts forced air cooling£¨IC666 or IC616£©or water cooling£¨IC41W£©£»
Installation method: IMB3£¬ Protection grade: IP54£¬ slip ring protection grade: IP23£»
Rotor employs mature variable-frequency insulation structure£¬ similar to the one of traction motor£¬ with capability of anti-high-frequency harmonic impulse.
Insulation grade of stator/rotor£ºH/H£»
It adopts insulated bearing system and earthing brush£¬ to eliminate the effect of shaft current on life of bearing.
Stator winding is equipped with thermal resistance sensor£¬ to monitor the temperature rise of stator winding in real-time;
Bearing is equipped with thermal resistance sensor£¬ to monitor temperature rise of bearing in real time;
Service life of carbon brush is long£¬ equipped with the function of automatically monitoring wear of carbon brush;
The required power of frequency converter is small£¬ thus price of integrated generator is low;¡¡
Adjustable range of power factor is wide£¬ without power factor compensation device;
Range of rotating speed is wide. When paralleling in the grid£¬ it has little impulse and interference on power network.
Distortion of output harmonics is small.
