新型浸润式蒸发冷却电机定子三维温度场的研究

浸润式蒸发冷却优越于其它冷却方式，为电机定子的运行提供了安全、可靠、高效的绝缘及传热的整体大环境，其对应的温度分布状况值得深入研究。文中以一台高功率密度、高速整流异步发电机的定子为研究对象，根据制造企业的工艺允许条件，提出一种适合于浸润式蒸发冷却电机定子的新型绝缘结构，对该结构中的气、液、固三相电绝缘体系的温度场分布等问题进行了系统的理论仿真计算与模型试验，基于仿真和试验两方面的结果，对这一结构给予了可行性分析，确定了其运行时的额定负荷，为以后同类型电机的设计提供理论依据。

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 its temperature distribution is worthy of being profoundly researched. According to the acceptant technics condition of the manufacture, a kind of new stator insulation structure adapting to evaporative cooling mode is proposed. The research is based on a commutate asynchronism generator of high power density and speed. By calculation and testing, this paper studies the temperature distribution of the new insulation system formed by gas, liquid, and solid. And compared calculation with testing results, a feasible analysis 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.
