TA1-850kW AC brushless excitation synchronous gene

TA1-850kW generator is matching for GHFD850-2 type VSCF wind turbine generator systems, it adopts hybrid cooling of air and water. The generator adopts maintenance-free structure, it can be decouplded completely with grid and has an excellent adaptability for grid getting the high quality electric power, especially for the ability of low voltage fault ride through. The stator adopts indirect water-cooling which has a good cooling effect. The rotor adopts salient-pole mode that the heat can be taken away by air from interelectrode ventilation. The whole turbine adopts horizontal type and it is superior stable and integrity. The exciter frame adopts casting zone and radiating rib structure that has good heat dissipation. After strictly testing, the performance index is excellent and has achieved an international level of the same type generator.Rated power: 850kW Working standard: S1 Continuous operation Power range: 150kW∼850kW Power factor: 0.95∼1.0 Speed range: 1040∼2000 rpm Rated speed: 1710 rpm Stator voltage: 2×3×690730V Rated current: 2×355A Efficiency at rated power: ≥96.0 Installation: IM B 3 (DIN IEC 34-7) Protection grade: IP 54 (DIN IEC 34-5) Cooling system leak testing pressure: 1MPa 30min Pole number 4 Winding connection: Dual-winding system, Y connected, star-shaped leads, as 60 degrees Insulation grade: F/H
