日常工作中**常見(jiàn)的三相異步電動(dòng)機(jī)有鼠籠型電機(jī)和繞線(xiàn)式電機(jī)。這是根據(jù)它們的轉(zhuǎn)子結(jié)構(gòu)來(lái)分類(lèi)的。從外觀上看，明顯的區(qū)別就是繞線(xiàn)式電機(jī)帶轉(zhuǎn)子滑環(huán)，鼠籠式電機(jī)不帶。鼠籠型電機(jī)轉(zhuǎn)子繞組是自己短路的繞組，在轉(zhuǎn)子在每個(gè)槽中放有一根導(dǎo)體，導(dǎo)體比鐵芯長(zhǎng)，在鐵芯兩端用兩個(gè)端<span

三相異步電動(dòng)機(jī)的缺相運(yùn)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(kāi)而造成的一種電動(dòng)機(jī)運(yùn)行狀態(tài)，三相異步電動(dòng)機(jī)的繞組燒毀大多數(shù)是由于缺相運(yùn)行造成的。下面，我介紹一個(gè)簡(jiǎn)便方法針對(duì)缺相故障進(jìn)行保護(hù)。一、對(duì)于星形接法電動(dòng)機(jī)，由于三相交流電的失量和為零，其中性點(diǎn)對(duì)地電壓理論上為零，但實(shí)際上三相電壓不會(huì)平衡，總要相差幾伏電壓。當(dāng)電機(jī)缺相運(yùn)行時(shí)，由于定子三相電壓不平衡，中性點(diǎn)對(duì)地的零序電壓升高，當(dāng)電機(jī)滿(mǎn)負(fù)荷運(yùn)行時(shí)，此零序電壓可達(dá)達(dá)25～45伏。此時(shí)，可通過(guò)串接于電機(jī)中性線(xiàn)上的零序電壓繼電器來(lái)對(duì)電機(jī)進(jìn)行保護(hù)，如圖1所示。電機(jī)正常運(yùn)行時(shí)，中性點(diǎn)對(duì)地電壓較低，Kv不動(dòng)作。，中性蘭對(duì)地電壓升高，使Kv動(dòng)作，它的常閉觸點(diǎn)斷開(kāi)而切斷KM線(xiàn)圈電源，隨即主電路斷電。二、對(duì)于定子繞組三角形接法的電機(jī)，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(diǎn)，如圖2所示。由于實(shí)際電路中，中性點(diǎn)對(duì)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(chǎng)上的小型中間繼電器(12或24伏)來(lái)代替電壓繼電器。這樣更方便些。聯(lián)創(chuàng)電機(jī)具有一支經(jīng)驗(yàn)豐富、技術(shù)力量過(guò)硬的專(zhuān)業(yè)技術(shù)人才管理團(tuán)隊(duì)。</p><div

style="text-indent:25px">高壓電機(jī)可以做得功率很大，比較大可達(dá)到幾千甚至幾萬(wàn)千瓦。這是因?yàn)?，在同樣的輸出功率時(shí)，高壓電機(jī)的電流可比低壓電機(jī)小很多（基本上是與電壓成反比關(guān)系），例如500kW、4極電機(jī)的額定電流，額定電壓為380V時(shí)為900A左右，而額定電壓為10kV時(shí)只有30A左右。所以高壓電機(jī)繞組可用較小的線(xiàn)徑。由此，高壓電機(jī)的定子銅損耗也會(huì)比低壓電機(jī)少。對(duì)于較大功率的電機(jī)，使用低壓電時(shí)，則因需要較粗的導(dǎo)線(xiàn)而需要很大面積的定子槽，使定子鐵芯直徑做得很大，電機(jī)整個(gè)體積也會(huì)很大。對(duì)于較大容量的電機(jī)，高壓電機(jī)所用電源和配電設(shè)備比低壓電機(jī)的總體投資少，并且線(xiàn)路損耗小，可節(jié)省一定的耗電量。特別是10kV的高壓電機(jī)，可直接使用網(wǎng)絡(luò)電源（我國(guó)提供給用戶(hù)的高壓電一般都是10kV），這樣在電源設(shè)備（主要是變壓器）上的投資會(huì)更少，使用也較簡(jiǎn)便，故障率也會(huì)較少。以客戶(hù)至上為理念，為客戶(hù)提供咨詢(xún)服務(wù)。東營(yíng)三相異步電機(jī)</p><p
