PROBLEMS OF TURBOGENERATORS LARGE AND MEDIUM POWER COOLING
A.P.Gruboi, A.V.Tret ak,
State enterprise plant “Electrotyazhmash”,
299, Moskovskyi Avenue, Kharkiv, 61089, Ukraine.
Turbogenerators large and medium power cooling system disadvantages are identified. The main problems of the stator core cooling
are identified also. The variant of heat transfer enhancement in the stator core is proposed. The variant bases on the cooling
channels design, taking into account the air distribution and heat load in the bars. As a result, proposed design provides the maximal
bars temperature decreasing on the 5oC and insulation lifetime As the bars have minimum lifetime in turbogenerator design, that is
why given improvement makes better reliability of the design. References 2, figure 1.
Key words: turbo-generator of high power, thermal-hydraulic calculation, the stator, the cooling system.
