Study on 3D temperature distribution in new evaporative cooling asynchronous generator

Evaporative cooling, is superior to other cooling methods. It offers a safe, reliable, and effective whole surrounding for insulation and heat transfer of the running stator. So it´s temperature distribution is worthy of being profoundly researched. According to the acceptant technics condition of the manufacture, the paper offers a kind of new stator insulation structure adapting to evaporative cooling mode. It is based on a commutate asynchronism generator of high power density and speed. By calculation and testing, this paper studies the heat distribution of the new insulation system formed by gaseity liquid, and solid. And by comparing between calculation and testing results, a feasible research to the new insulation structure has been given. While the rated load of the new insulation structure stator is decided. The paper´s valuable research conclusion may be regarded as an academic foundation for the same generators.
