Product name: DOUBLE-FED ASYNCHRONOUS WIND TURBINE GENERATION [Technical data sheet]
[The outlook and installs the size ]
Characteristic and use:
Combining the self research and development with introduced German technology,manufactured according to advanced techniques and standards, the generators feature high reliability and long operating life.
Electrical machinery performance:  

Matched with a lower power and loss frequency converter, making the entire turbine a higher efficient operation.
Being able to adjust the active and reactive powers smoothly.
The stator and rotor windings are vacuum-pressure impregnation processed so that the whole insulation performance of the generator is excellent and dependable, and also its mechanical strength is higher. A special insulation structure is used for the rotor, forming a strong ability against the highfrequency harmonic impulse from frequency converter.
The stator windings and bearings are fitted with the platinum thermistor Pt100 for monitoring and controlling the winding and bearing temperatures.
The bearings are quipped with an automatic grease-charging system and a manual grease- charging system,for user’s free operating selection.
The slipring system is fitted with a brush-worn alarm unit.
A lightning protection device for stator and rotor can be mounted according to user’s demand.The insulation bearings or a bearing-insulating system and the earthing brushes are applied to eliminate the influence of shaft current.
A space heating system working at a standstill of the generator is builtin.
     装有停机加热系统。

Model explanation:  

 

Structure synopsis:  
Mounting type IMB3, protection degree IP54, insulation class H and temperature rise checked according to class F. Cooling method IC616 orIC666(with air/aircooler),and the air/water cooling type can also be made on user’s request.
A frame-type box structure is adopted for the housing which ensures a high reliability of the generator during its operation.
