摘要
在直接空冷机组中,空冷岛空冷风机是设计采用变频调速运行,本文对风机电动机是选用变频调速专用还是普通电动机进行可行性分析,并提出必要的选型技术条件,确保能够在变频谐波的影响下安全可靠运行,同时又运行经济,为同类型工程提供参考。
In direct air cooling units,frequency conversion was designed for the operation of air cooling fan in air cooling island. In this paper,feasibility analysis had been done to select special or ordinary motor of variable frequency speed regulations,and necessary selection of technical conditions has been put forward, which ensures the safe and reliable operation under the influence of variable frequency harmonic. At the same time,it runs economically and provides reference for similar engineering.
