1.Y—Δ降壓起動的原理：把正常運行時，定子繞組應作三角形聯(lián)接的籠型異步電動機在起動時接成Y形，起動電壓從380V→220V，從而減小起動電流。待轉速上升后，再改接成Δ聯(lián)結，投入正常運行。這是一種zui常用的降壓起動。起動時繞組承受的電壓為額定電壓的1/
倍，起動電流為三角形接法時的1/3。
2．控制過程:
主回路：合上QS→控制線路接上電源
控制回路：
（1）SB2按鈕按下→KT、KM3線圈得電→KM3觸頭閉合→KM1線圈得電自鎖→KM1、KM3主觸頭閉合→電動機星形聯(lián)接起動。
（2）KT整定時間到→延時斷開觸點斷開→KM3線圈失電→KM3常開觸頭斷開，常閉復位→KT失電，KM2線圈得電→KM2主觸頭閉合→電動機三角形聯(lián)接正常運行。
3．Y—Δ降壓起動投資少，線路簡單，操作方便，但起動轉矩小，適用于空載或輕載場合，普遍應用于空載或輕載的正常運行是三角形聯(lián)結的籠型異步電動機起動。
