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。四川大型電機(jī)維修聯(lián)創(chuàng)電機(jī)重信譽(yù)、守合同，嚴(yán)把產(chǎn)品質(zhì)量關(guān)，熱誠(chéng)歡迎廣大用戶(hù)前來(lái)咨詢(xún)考察，洽談業(yè)務(wù)！</p><div

三相電動(dòng)機(jī)在起動(dòng)時(shí)，起動(dòng)電流很大，可達(dá)到額定電流的4~7倍，很大的起動(dòng)電流，在短時(shí)間內(nèi)會(huì)在線路上造成 </p> <p> 較大的電壓降落，這不僅影響電動(dòng)機(jī)本身的起動(dòng)也會(huì)影響到同**路上的其他電動(dòng)機(jī)和電器設(shè)備的正常工作。 </p> <p> 為此，對(duì)大容量電動(dòng)機(jī)且起停頻繁時(shí)，為了限制起動(dòng)電流，必須采取降壓起動(dòng)。所謂降壓起動(dòng)，就是在電動(dòng)機(jī)起 </p> <p> 動(dòng)時(shí)降低加在電動(dòng)機(jī)定子繞組上的電壓，當(dāng)電動(dòng)機(jī)轉(zhuǎn)起來(lái)以后，再將加在定子繞組上的電壓恢復(fù)到正常值。由于 </p> <p> 電流與電壓成正比關(guān)系，所以降低起動(dòng)時(shí)的電壓能減小起動(dòng)電流。但是由于電磁轉(zhuǎn)矩與電動(dòng)機(jī)定子繞組端電壓的 </p> <p> 平方成正比，所以電動(dòng)機(jī)在降壓起動(dòng)時(shí)，起動(dòng)轉(zhuǎn)矩相應(yīng)減小，故降壓起動(dòng)適用于空載或輕載下的起動(dòng)
