Abstract :
With the change of the cooling method, the configuration of insulation in generator is changed. Measures have been took to analyses and optimize the configuration of insulation. In this paper, investigation on new coolant insulation, which is considered to be a possible replacement of main insulation of stator in generator, is carried out. The insulation properties of gas-liquid two-phase flows in evaporative cooling system of generator are studied. It has been proved that the insulation characteristic in gas-liquid two-phase flow system is different to either in gas or in liquid.
