Hydrogen-cooled turbogenerator of TVF-125-2 type with nominal capacity of 125 MW. 70-765-2023

Turbogenerator TVF-125-2 two-pole, synchronous, designed to generate electricity in continuous rated mode S1 according to GOST IEC 60034-1 when paired with a steam turbine and installed indoors. 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 IC7H1W7 according to GOST R IEC 60034-6. The turbogenerator has a hydrogen self-ventilation system with a closed cycle, direct hydrogen cooling of the rotor winding, indirect hydrogen cooling of the stator winding and direct hydrogen 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.
