110KW-160KW水泵，有沒(méi)有誰(shuí)用過(guò)星三角啟動(dòng)的，幫忙給個(gè)解決方案才行，剛開(kāi)始空載的時(shí)候啟動(dòng)都沒(méi)有問(wèn)題，現在帶負載運行了，星和三角接觸器轉換的時(shí)候，總空開(kāi)掉閘？對于整個(gè)過(guò)程的觀(guān)察，在接觸器轉換的過(guò)程中，星接觸器有打火花現象，這是不是所說(shuō)的電弧引起的短路導致空開(kāi)掉閘呢？希望高手們給個(gè)解決的辦法��？？？

你空載試過(guò)，說(shuō)明沒(méi)有問(wèn)題，在帶負載的情況應該是星三角轉換的時(shí)間太短了，你把這個(gè)時(shí)間設置在20S左右試試
