摘　　要：以直接空冷600 MW机组为例,分析了空冷岛轴流风机叶片异常断裂的原因,提出了预防叶片断裂的措施,供同类型汽轮机空冷岛轴流风机叶片安装时参考。Taking the 600 MW direct air-cooled unit as example,the reasons of abnormal fracture of axial flow fan blade in air cooling island were analyzed. The measures for preventing blade fracture were proposed,which can be used as reference for similar steam turbine in installation of axial flow fan blade in the air cooling island.
