摘　　要：PS转炉鼓风机大都采用入口导叶调节风机流量,存在能耗大、风量浪费严重及风机喘振等问题。本文详细分析了存在问题的原因,提出采用高压变频调速技术来解决鼓风机生产中出现的问题。介绍了系统主回路和二次回路控制方案及变频器配置,分析了改造效果。PS converter blower mostly uses inlet guide vane to adjust fan flow rate, and it has the problems of large energy consumption, serious flow rate waste and fan surge and others. This paper analyzes the causes of the problems in detail, and puts forward the scheme of using high voltage frequency conversion speed regulation technology to solve the problems in PS converter production. The main circuit and the secondary circuit control scheme and the configuration of frequency inverter are introduced, and the transformation effect is analyzed.

关 键 词：PS转炉鼓风机 风机喘振 变频调速 节电效益
