電動(dòng)機(jī)的控制系統(tǒng)由開關(guān)、保險(xiǎn)絲、主副接觸器、繼電器、溫度、感應(yīng)裝置等組成，相對(duì)較復(fù)雜。故障多種多樣，常需要借助控制原理圖分析排查。平時(shí)要注意保持控制箱內(nèi)、外清潔干燥，不能有水、油污，定期（每周）用小風(fēng)機(jī)吹干凈箱內(nèi)各元件及接線柱、排上的灰塵，或用刷子蘸電器清潔劑刷干凈，以免影響接觸器、繼電器的工作或絕緣。設(shè)有烘潮電阻的控制箱，一般不要隨意關(guān)掉加熱開關(guān)。還應(yīng)保持箱體接地可靠，預(yù)防觸電。對(duì)采用星形-三角形(Y-△)方法啟動(dòng)的（轉(zhuǎn)換延時(shí)約5秒）電動(dòng)機(jī)，要察看其轉(zhuǎn)換啟動(dòng)情況是否正常。通常，生產(chǎn)廠家對(duì)電動(dòng)機(jī)的啟動(dòng)周期(即每分鐘啟動(dòng)次數(shù))有嚴(yán)格規(guī)定，會(huì)在起動(dòng)控制箱上有*示標(biāo)貼，提醒使用者防止電動(dòng)機(jī)因頻繁啟動(dòng)而損壞，同時(shí)，也為防止起動(dòng)控制箱內(nèi)的一些電器組件(如起動(dòng)電抗器等)發(fā)熱燒毀。所以，對(duì)起停頻繁或電流大的電動(dòng)機(jī)控制系統(tǒng)，應(yīng)縮短檢查保養(yǎng)周期。定期檢查熱過載繼電器的保護(hù)功能(可撥動(dòng)旁邊的小紅標(biāo)色制)其設(shè)定動(dòng)作值不要超過電動(dòng)機(jī)銘牌的額定電流值，確保能起到過載保護(hù)的作用。 </p> <p> <br /> </p><p> 吊入式機(jī)座是一個(gè)長(zhǎng)方體的箱式結(jié)構(gòu)，機(jī)座內(nèi)部軸向有筋，用于支撐和固定定子。定子是從上方放入機(jī)座，靠定子壓圈與機(jī)座軸向筋定位并保證氣隙均勻度。再用螺栓將定子與機(jī)座緊固。機(jī)座端端板的內(nèi)止口與端蓋的外止口緊密配合，能充分保證定、轉(zhuǎn)子之間的氣隙均勻度。壓入式機(jī)座大多是通過熱套方式將定子套入機(jī)座，該方式下機(jī)座與定子的同心度容易保證，但相對(duì)與吊入式機(jī)座便捷性要遜色一些。 </p> <p> ● 定子線圈：定子線圈是雙層疊繞阻，絕緣等級(jí)為F級(jí)，電壓等級(jí)為3KV及以上的電機(jī)都有防電暈措施。 </p> <p> ● 轉(zhuǎn)子線圈：繞線電機(jī)的轉(zhuǎn)子線圈是雙層波繞組，采用矩形銅排，絕緣等級(jí)要求為F級(jí)。 </p> <p> ● 定子：定子通常采用磁性槽楔，根據(jù)需要也可用非磁性槽楔。線圈端部之間應(yīng)采用適型材料墊緊，并與端箍、支撐桿扎牢在一起，經(jīng)過真空壓力整浸無(wú)溶劑漆后，整個(gè)定子成為一個(gè)整體，增強(qiáng)了其機(jī)械性和防潮能力。<span style="display:none;"></span> </p> <p> ● 轉(zhuǎn)子：鼠籠型電機(jī)一般情況下采用鑄鋁轉(zhuǎn)子，這種轉(zhuǎn)子運(yùn)行可靠，并具有較好的起動(dòng)性能，它可以滿壓直接起動(dòng)。根據(jù)需要也可采用銅條轉(zhuǎn)子，銅條轉(zhuǎn)子電機(jī)效率相對(duì)較高，但成本也要高好多。 </p> <p> ● 軸大多焊有輻板，并經(jīng)過熱處理，具有較好的機(jī)械性能。高壓電機(jī)軸的熱處理非常關(guān)鍵，稍有不慎，會(huì)出現(xiàn)斷軸問題。公司狠抓產(chǎn)品質(zhì)量的提高，逐年立項(xiàng)對(duì)制造、檢測(cè)、試驗(yàn)裝置進(jìn)行技術(shù)改造。</p><div style="width:100%;text-align:

高壓電機(jī)直接啟動(dòng)就是在全電壓條件下直接啟動(dòng)電機(jī)。如果電網(wǎng)條件允許，可以采用直接啟動(dòng)。但在實(shí)際生產(chǎn)過程中往往由于電網(wǎng)容量有限，很少采用直接啟動(dòng)。由于采用直接啟動(dòng)時(shí)，啟動(dòng)電流大，使電壓下降幅度較大，對(duì)于供電系統(tǒng)有較大的沖擊，如果壓降超過一定值，有可能導(dǎo)致上級(jí)變電所跳閘。故在實(shí)際運(yùn)行中很少采用這種直接啟動(dòng)方法。串聯(lián)電抗器啟動(dòng)就是在電機(jī)啟動(dòng)的時(shí)候串入電抗器，以限制和降低電機(jī)啟動(dòng)時(shí)的啟動(dòng)電流及電網(wǎng)壓降，當(dāng)電機(jī)運(yùn)行穩(wěn)定且電流達(dá)到一定值時(shí)，切除電抗器變?yōu)殡姍C(jī)直接啟動(dòng)模式。由于啟動(dòng)過程中電機(jī)端的電壓也下降，容易導(dǎo)致啟動(dòng)轉(zhuǎn)矩不夠，在啟動(dòng)過程中還會(huì)出現(xiàn)一個(gè)二次沖擊的過程。自耦變壓器啟動(dòng)是指電動(dòng)機(jī)啟動(dòng)時(shí)利用自耦變壓器來(lái)降低加在電動(dòng)機(jī)定子繞組上的啟動(dòng)電壓。待電動(dòng)機(jī)啟動(dòng)后，再使電動(dòng)機(jī)與自耦變壓器脫離，從而在全壓下正常運(yùn)行。優(yōu)點(diǎn)是可以按容許的啟動(dòng)電流和所需的啟動(dòng)轉(zhuǎn)矩來(lái)選擇自耦變壓器副邊的不同抽頭實(shí)現(xiàn)降壓?jiǎn)?dòng)，而且不論電動(dòng)機(jī)定子繞組采用星形接法或三角形接法都可以使用。缺點(diǎn)是設(shè)備的體積較大，因而成本較貴。陜西三相同步電機(jī)維修</p><p
