Air-cooled turbogenerator of TF-90G-2 type with rated capacity of 90 MW. 70-468-2021

Turbogenerator TF-90G-2U3 two-pole, synchronous, designed to generate electricity in continuous rated mode S1 according to GOST IEC 60034-1 when paired with a gas turbine and installed in a closed room. The turbogenerator complies with the technical conditions, as well as GOST IEC 60034-1, GOST IEC 60034-3, "Rules for Electrical Installations" and a set of technical documentation.
The cooling method of the turbogenerator is IC71W according to GOST R IEC 60034-6. The turbogenerator has a closed-cycle air self-ventilation system, direct air cooling of the rotor winding, indirect air cooling of the stator winding and direct air cooling of the stator iron. The main units: stator, rotor, brush and contact apparatus, bearings. The turbogenerator is manufactured according to the classical technology of vacuum-impregnation impregnation of insulation, which provides high maintainability.
