1000/200kW Duplex Winding Water-cooled
	
1000/200kW Duplex Winding Water-cooled wind-driven generator
Machine can be switched to small power winding operation when wind power is small£¬ and switched to high power winding operation when wind power is good. In this way£¬ wind power can be sufficiently used£¬ and integrated operation efficiency of wind –driven generator can be improved.
Main Technical Features
Cooling Method: Generator IC41W£¬good heat dissipation.
Installation mode£ºIMB3£¬ protection grade£ºIP54£»
It has two sets of stator windings£¬ one is 1000kW winding£¬ the other one is 200kW winding£¬ Through change of wind speed£¬ machine can be switched to different state to generate power£¬ thus operation efficiency of generator can be improved.
Stator applies vacuum pressure impregnation varnish£¬ and winding insulation is very reliable.
Rotor employs common squirrel-cage structure£¬ which enjoys high reliability.
Stator insulation grade: H£»
Automatic lubricator is applied to fuel the bearing£¬ easy for maintenance.
Stator winding is equipped with thermal resistance sensor for monitoring temperature rise of winding in real-time;
Bearing is equipped with thermal resistance sensor for monitoring temperature rise of bearing in real-time;
Motor is embedded with moisture-proof heater£¬ to prevent condensation at winding ends£¬ when the machine is shutdown.
All the surface structure applies three-proofing treatment to meet the requirement of three-proofing£¬ which can improve surface anticorrosion capability.
