本文叙述了如何采用1:5相似通风模型对650MW级全空冷水轮发电机的通风系统进行模拟研究,一方面检验真机通风系统的合理性并优化通风结构,另一方面验证网络计算方法,并为更大容量全空冷水轮发电机的研制作技术储备。 This paper describes how to simulate the ventilation system of a 650MW air-cooled generator with a 1: 5 similarity ventilation model. On the one hand, it verifies the rationality of the ventilation system of a real machine and optimizes the ventilation structure. On the other hand, it verifies the network calculation method, And for more capacity of all air-cooled turbine generator research and development for technical reserves.
