摘　　要：由哈尔滨电机厂有限责任公司独立设计、独立制造世界上单机容量最大、结构尺寸最大、推力负荷最大的三峡右岸电站26#全空冷巨型水轮发电机于2007年7月成功并网发电。这标志着水轮发电机空冷技术的重大突破,是水电建设史上一个重大里程碑。本文重点介绍全空冷水轮发电机的电磁、通风、绝缘系统及结构的设计特点,提供了三峡右岸全空冷和半水冷水轮发电机主要运行性能参数对比,并展望了容量为1000MVA发电机采用全空冷的可能性。The unit 26^# of fully air cooled huge hydrogenerator with largest capacity, largest dimension and thrust load around the world, self designed and self manufactured by Harbin Electric Machinery Company, installed in three Gorges right bank power station was put into operation successfully in July, 2007. It is a break through of air cooled technology as well as a milestone of hydropower construction history. The characteristics of electromagnetic, ventilation system, insulation system and structural design are presented briefly. A comparison of main operating performance parameters for both fully air cooled and water cooled generators in Three Gorges right bank power station is provided. The possibility of application for fully air cooled hydrogenerator with capacity of 1000MVA is in prospect.
