Turbogenerator of TVF-220-2 type with hydrogen cooling with nominal capacity 220 MW. 70-449-17

Turbogenerator TVF-220-2 two-pole, synchronous, three-phase current frequency 50Hz, general industrial version. The turbogenerator is designed for power generation in continuous operation mode S1 according to GOST IEC 60034-1 in direct connection with a steam turbine and installation 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 turbogenerator has a hydrogen cooling system. The turbogenerator is made with direct hydrogen cooling of the rotor winding with hydrogen distribution from under the groove channel, indirect hydrogen cooling of the stator winding with direct hydrogen cooling of the stator iron. The main units: stator, rotor, brush and contact apparatus, bearings. The turbogenerator is manufactured by the classical technology of vacuum-impregnation impregnation of insulation, which provides high maintainability.
