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用的呢?下面為您詳細闡述。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。江蘇三相異步電機廠家排名聯(lián)創(chuàng)電機為客戶服務，要做到更好。</p><div

style="text-indent:25px">高壓電機可以做得功率很大，比較大可達到幾千甚至幾萬千瓦。這是因為，在同樣的輸出功率時，高壓電機的電流可比低壓電機小很多（基本上是與電壓成反比關系），例如500kW、4極電機的額定電流，額定電壓為380V時為900A左右，而額定電壓為10kV時只有30A左右。所以高壓電機繞組可用較小的線徑。由此，高壓電機的定子銅損耗也會比低壓電機少。對于較大功率的電機，使用低壓電時，則因需要較粗的導線而需要很大面積的定子槽，使定子鐵芯直徑做得很大，電機整個體積也會很大。對于較大容量的電機，高壓電機所用電源和配電設備比低壓電機的總體投資少，并且線路損耗小，可節(jié)省一定的耗電量。特別是10kV的高壓電機，可直接使用網(wǎng)絡電源（我國提供給用戶的高壓電一般都是10kV），這樣在電源設備（主要是變壓器）上的投資會更少，使用也較簡便，故障率也會較少。</p><p> 在電動機停止運行時，要定期（每月）用絕緣表測量其各相對地或相間絕緣電阻，并與上月測試結果相比較，以便及時發(fā)現(xiàn)絕緣缺點，發(fā)現(xiàn)不良時用烘潮燈烘烤以提高絕緣，避免因絕緣太低（推薦值>1兆歐）擊穿繞組燒壞電動機。沒有烘潮電加熱的電動機除非特殊情況，不要隨意關掉加熱開關。在潮濕天氣和冬季時要特別注意電動機的防水、防潮和烘干。對露天及潮濕場所的電動機要特別注意水密，對懷疑嚴重受潮或濺過水的電動機，使用前更應認真檢查。如果發(fā)現(xiàn)電動機浸泡水，只要將電動機解體后抽出轉子，并用壓縮空氣吹干后，再用烤燈從電動機定子內兩端烘烤，直止電動機絕緣升至正常。公司狠抓產(chǎn)品質量的提高，逐年立項對制造、檢測、試驗裝置進行技術改造。</p><div

電動機在運行中的狀況，可以通過電動機電流的大小、溫度的高低、聲響的差異等表面的特征表現(xiàn)出來，因此電工人員可以通過眼、耳、手、鼻，同時借助儀表、工具加以監(jiān)視和檢測，發(fā)現(xiàn)異常，應及時停機處理，排除故障。 </p> <p> (1)監(jiān)視電動機的溫度。運行中的電動機都要發(fā)熱，其溫升不應超過銘牌上的允許限度。電動機的絕大部分故障都會使它的定子電流增大，溫度升高，因此，如果發(fā)現(xiàn)電動機的溫度超過允許值，應立即停機檢查，查明嚴重發(fā)熱的原因，排除故障后才可以運行。聯(lián)創(chuàng)電機過硬的產(chǎn)品質量、質量的售后服務、認真嚴格的企業(yè)管理，贏得客戶的信譽。陜西高壓電機報價</p><p

為此，對大容量電動機且起停頻繁時，為了限制起動電流，必須采取降壓起動。所謂降壓起動，就是在電動機起 </p> <p> 動時降低加在電動機定子繞組上的電壓，當電動機轉起來以后，再將加在定子繞組上的電壓恢復到正常值。由于 </p> <p> 電流與電壓成正比關系，所以降低起動時的電壓能減小起動電流。但是由于電磁轉矩與電動機定子繞組端電壓的 </p> <p> 平方成正比，所以電動機在降壓起動時，起動轉矩相應減小，故降壓起動適用于空載或輕載下的起動菏澤電機報價</p><p style="text-indent:25px">山東聯(lián)創(chuàng)電機有限公司注冊資金300-500萬元，是一家擁有11~50人***員工的企業(yè)。公司業(yè)務涵蓋[ "大型高壓電機", "中型高壓電機", "電機維修"
