摘要
文章阐述了巨型水轮发电机全空气冷却方式的主要技术难点。以三峡右岸840 MVA的水轮发电机为例对全空冷技术进行了详细的、具体的讨论,并对三峡右岸全空冷水轮发电机的通风及温升进行了计算与实测值的对比分析。
This paper describes the major technical difficulty in design of huge fully air cooled hydro-genera- tor.Take the 840MVA hydro-generator for Three-Gorges Right Bank Hydropower Station as an example, discusses the air-cooling technique in detail.The calculated result and the measured value of ventilation and temperature rise of this type of generator are compared and analyzed.
