三相異步電動機的缺相運行是指三相供電電源缺少一相或三相繞組有一相從電源斷開而造成的一種電動機運行狀態(tài)，三相異步電動機的繞組燒毀大多數(shù)是由于缺相運行造成的。下面，我介紹一個簡便方法針對缺相故障進行保護。一、對于星形接法電動機，由于三相交流電的失量和為零，其中性點對地電壓理論上為零，但實際上三相電壓不會平衡，總要相差幾伏電壓。當(dāng)電機缺相運行時，由于定子三相電壓不平衡，中性點對地的零序電壓升高，當(dāng)電機滿負(fù)荷運行時，此零序電壓可達(dá)達(dá)25～45伏。此時，可通過串接于電機中性線上的零序電壓繼電器來對電機進行保護，如圖1所示。電機正常運行時，中性點對地電壓較低，Kv不動作。，中性蘭對地電壓升高，使Kv動作，它的常閉觸點斷開而切斷KM線圈電源，隨即主電路斷電。二、對于定子繞組三角形接法的電機，可將星形接法的三只電容器(容量2～4uF為好)接于三角形繞組上，引出人為中性點，如圖2所示。由于實際電路中，中性點對地總有幾伏電壓，因此可以把電壓繼電器整定到12～24伏。此外也可使用市場上的小型中間繼電器(12或24伏)來代替電壓繼電器。這樣更方便些。

看：每天巡查時看電動機工作電流的大小和變化，看周圍有沒有漏水、滴水，會引起電動機絕緣低擊穿而燒壞。還要看電動機**是否有影響其通風(fēng)散熱環(huán)境的物件？看風(fēng)扇端蓋、扇葉和電動機外部是否過臟需要清潔？要確保其冷卻散熱效果。無論誰發(fā)現(xiàn)問題，都應(yīng)及時處理。聽：認(rèn)真細(xì)聽電動機的運行聲音是否異常，因機房噪音較大，可借助于螺絲刀或聽棒等輔助工具，貼近電動機兩端聽，如果經(jīng)常聽，不但能發(fā)現(xiàn)電動機及其拖動設(shè)備的不良振動，連內(nèi)部軸承油的多少都能判斷，從而及時作出添加軸承油，或更換新軸承等相應(yīng)的措施處理，避免電動機軸承缺油干磨而堵轉(zhuǎn)、走外圓、掃膛燒壞。多數(shù)廠家考慮到大型電動機解體更換軸承的困難，會采用開式軸承，定期（2000h）加油時需注意使用電機標(biāo)示軸承油（-35℃～+140℃），并將下端放油口打開或另一邊的悶頭螺絲拆卸開，以便將舊油擠換出來（注意補充油定額）防止加油時因壓力大把油擠到電動機內(nèi)部，運轉(zhuǎn)時濺到定轉(zhuǎn)子上，影響電動機的散熱功能等。聯(lián)創(chuàng)電機用先進的生產(chǎn)工藝和規(guī)范的質(zhì)量管理，打造優(yōu)良的產(chǎn)品！</p><div

在電氣工程施工中，如何計算不同電壓等級的三相電動機額定電流呢，這里有一個口訣：容量除以千伏數(shù)，商乘系數(shù)點七六。這個口訣具體是怎么應(yīng)用的呢?下面為您詳細(xì)闡述。由公式及口訣均可說明容量相同的電壓等級不同的電動機的額定電流是不相同的，即電壓千伏數(shù)不一樣，去除以相同的容量，所得“商數(shù)”顯然不相同，不相同的商數(shù)去乘相同的系數(shù)0.76，所得的電流值也不相同。若把以上口訣叫做通用口訣，則可推導(dǎo)出計算220、380、660、3.6kV電壓等級電動機的額定電流**計算口訣，用**計算口訣計算某臺三相電動機額定電流時，容量千瓦與電流安培關(guān)系直接倍數(shù)化，省去了容量除以千伏數(shù)，商數(shù)再乘系數(shù)0.76。三相二百二電機，千瓦三點五安培。常用三百八電機，一個千瓦兩安培。低壓六百六電機，千瓦一點二安培。高壓三千伏電機，四個千瓦一安培。高壓六千伏電機，八個千瓦一安培。公司將以質(zhì)量的產(chǎn)品，完善的服務(wù)與尊敬的用戶攜手并進！廣西三相異步電機維修</p><p
