摘　　要：以越南斯雷博克Ⅲ电站机组通风系统为例,用理论计算与真机试验相结合的方法对全空冷水轮发电机通风系统进行了研究,给出了这类机组通风损耗的经验计算公式,并进行了真机通风试验。结果表明,理论计算和真机试验得出的总风量和通风损耗误差在10%以内,验证了该经验公式的准确性。Taking ventilation system of Vietnam Srepok Ⅲ station units as an example, this paper studies the ventilation system of fully air - cooling hydro - generator by the combination of theoretical calculation and prototype test, provides the experience formula of ventilation loss and conducts prototype test on ventilation. The result shows that the difference of the total air volume and ventilation loss calculated by theoretical calculation and prototype test is within 10% ,which verifies the accuracy of the experience formula.
