寶鋼集團某大型鋼鐵生產基地430m²燒(shao)結新技術生產線雙無(wu)刷勵磁(ci)同(tong)步(bu)電(dian)(dian)動(dong)機拖動(dong)燒(shao)結主(zhu)抽風(feng)機系統(tong)整(zheng)體實施(shi)，電(dian)(dian)機為兩臺7800kW同(tong)步(bu)電(dian)(dian)動(dong)機，兩套(tao)高壓變頻調速系統(tong)投入(ru)運行后(hou)，通過近(jin)兩個(ge)月的節(jie)(jie)能(neng)測評，平均(jun)節(jie)(jie)能(neng)率高達40%。

按照年運行7000h計算(suan)，兩臺(tai)高壓變(bian)頻調速系統可(ke)實現年節電9000萬度。
