Abstract
Temperature and thermomechanical loadings in elements stator are numerically investigated during start-up of turbogenerator ТГВ-200 at various charges of cooling gas through ventilating tubes of cores of a Minding. It is shown, at what value of charges the maximal temperatures of isolation of a winding and thermomechanical stress in its elements are close or exceed maximum permissible values for a corresponding class of thermal stability and breaking point of a material.
