Simulation for researching stator insulation structure of 135MW evaporative cooling turbo-generator by marinating

In order to apply evaporative cooling technical to a high voltage and large capacity turbo-generator that will be used for a main power generator, the problem of designing reasonable insulation structure is needed to be solved. This paper offers immerging evaporative cooling stator, according to its specialties. This paper calculates and analysis the electric field and the temperature field in immerging evaporative cooling stator insulation structure in detail, then summarizes the distribution rules or specialties of these two fields. As results this paper gives the stator insulation thickness which is reduced greatly compared with traditional one and the current density , aiming to 135 MW evaporative cooling turbo-generator. The conclusion has been tested and is worthy of using for reference.
