贴壁式结构水轮发电机定子温度场有限元法研究

摘要

本文利用ADINA软件对某贴壁式结构发电机定子进行温度场计算,得出与实测数据非常接近的解析结果,并在此基础上深入探讨铁心与机座的热态间隙、线棒与槽的间隙、河水温度等因素对定子温升以及河水带走热量值的影响关系,为贴壁式结构发电机定子的设计提供借鉴.%The stator thermal field of a holistic bulb turbine generator is analyzed by ADINA software,and it is shown that the calculation results are very close to the real-running data.Based on the FEM model, this paper studies how the clearances(the clearance between the stator frame and core, the clearance between coil and slot) and river water temperature influence the coil's temperature and the quantity of heat taken away by the river, and it provides references for the design of bulb turbine generator stator.
