style="text-indent:25px">所謂三相異步電動機的啟動是指電動機從接入電源開始轉(zhuǎn)動起，到達到額定轉(zhuǎn)速為止的這一過程。根據(jù)理論分析和實際測定，三相異步電動機啟動瞬間；定子繞組啟動電流很大，可達額定值的4~7倍。三相異步電動機為什么會有這么大的啟動電流呢？因為異步電動機在啟動瞬間轉(zhuǎn)子并不能立馬就轉(zhuǎn)動起來，此時轉(zhuǎn)子電磁感應的反電勢尚未建立起來，所以外電壓全部加在沒有反電勢的定子繞組上，其電路電流就是外電壓除以繞組的阻抗（用符號Z表示，是一種對電流其阻礙作用的能力，單位為歐姆公式Z=V/I表示），所以定子繞組電流很大。這么大的啟動電流將帶來以下不良后果：使電網(wǎng)電壓產(chǎn)生波動（特別是容量較大的電動機啟動時），從而影響到接在電網(wǎng)上的其它設(shè)備的正常運行。使電動機繞組發(fā)熱，絕緣老化，從而縮短了電動機的使用壽命。特別是對經(jīng)常需要啟動的電動機影響較大。啟動瞬間，由于三相異步電動機轉(zhuǎn)子電路功率因素較低，啟動轉(zhuǎn)矩并不很大。如果啟動轉(zhuǎn)矩小于負載轉(zhuǎn)矩則電動機將無法啟動。綜上所述，三相異步電動機啟動時的主要缺點是啟動電流較大。為了減小啟動電流，必須采用適當?shù)膯臃椒?。河北高壓電機多少錢聯(lián)創(chuàng)電機愿和各界朋友真誠合作一同開拓。</p><div

電機是生產(chǎn)、制造中比不可少的設(shè)備之一，為了保證電機正常工作，除了按操作規(guī)程正常使用、運行過程中注意正常監(jiān)視和維護外，還應該進行定期檢查，做好電機維護保養(yǎng)工作。對于新安裝的電動機定子絕緣電阻應大于2MΩ，轉(zhuǎn)子絕緣電阻應大于0.8MΩ；對使用中的電動機，定子絕緣電阻應大于0.5MΩ，轉(zhuǎn)子絕緣電阻大于0.5MΩ;如達不到一標準，應拆下來干燥；在烘干情況（50~70）定子絕緣電阻達1MΩ，轉(zhuǎn)子絕緣電阻應大于0.5MΩ。我們的機械設(shè)備能否正常工作，很重要的一部分就在于電機能否正常運轉(zhuǎn)。所以電機保養(yǎng)也是很重要的，很多人總是不注意保養(yǎng)或者不知道怎么保養(yǎng)，等到電機出現(xiàn)問題了，電機只能維修了，維修的話既要花錢，還耽誤工作。才后悔之前沒有做好保養(yǎng)。保養(yǎng)也是一門大學問。 </p><p 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(guān)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(shè)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(shè)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。聯(lián)創(chuàng)電機始終適應和促進工業(yè)發(fā)展為宗旨。</p><div
