General rules of electrical installation design

Sigre 2008 Electrosila Russia The main circumstance limiting the turbogenerator capacity having indirect gas cooling is the heating of the stator winding. The natural aspiration to reduce this stator winding heating is connected with the intensification of the convective heat exchange in the stator tooth zone. This purpose is achieved in the investigated design owing to bypass of cooling gas between adjacent radial ducts through slit axial duct...
