常用雙速風機的配電如何設計?看完這篇文章會刷新你的認知

發布日期:2022-10-15 點擊率:71

說到雙速風機的配電,不少電氣設計人員都覺得是疑點、難點。什么是雙速風機?所謂雙速風機,其實就是異步電機通過改變電機定子繞組的磁極對數達到改變轉速。使電機根據需要選用二級不同速度運行的風機。也就是平時作為通風應用時低速運行。一旦發生火災時,作為排煙風機高速運行的風機,大家知道,當改變異步電機的同步轉速時,也就相應地改變了電機的轉速。雙速風機選配的電機有YD型,YDT型兩種,YD型電機定子繞組接線形式有△/YY型,而YDT型電機定子繞組接線形式有Y/Y,3Y+Y/3Y,Y/YY三種。那么常用的雙速風機配電如何設計呢?下面本文就給大家詳細地講一講,看完文章,希望能給大家在工作帶來一定幫助。
