摘　　要：气隙取气斜流通风系统是大型汽轮发电机中应用较广的一种通风方式。总结国内外在改进气隙取气通风系统方面所做的研究工作,包括定转子间气隙气流改进、转子斜流风沟结构改进和进、出风斗结构优化等,并提出气隙取气通风系统有待进一步研究之处。Gap-pickup diagonal flow ventilation system was widely applied in large-scale turbo-generator rotors. Recently research on the improvement of diagonal flow ventilation system, including the improvement of flow condition on the gap, the development of the diagonal passage and the optimizing of wedge＇s structure, are summarized. In addition, the directions for development and investigation of this system were proposed.
