三相異步電機(jī)（Triple-phaseasynchronousmotor）是感應(yīng)電動(dòng)機(jī)的一種，是靠同時(shí)接入380V三相交流電流（相位差120度）供電的一類電動(dòng)機(jī)，由于三相異步電動(dòng)機(jī)的轉(zhuǎn)子與定子旋轉(zhuǎn)磁場以相同的方向、不同的轉(zhuǎn)速成旋轉(zhuǎn)，存在轉(zhuǎn)差率，所以叫三相異步電動(dòng)機(jī)。三相異步電動(dòng)機(jī)轉(zhuǎn)子的轉(zhuǎn)速低于旋轉(zhuǎn)磁場的轉(zhuǎn)速，轉(zhuǎn)子繞組因與磁場間存在著相對(duì)運(yùn)動(dòng)而產(chǎn)生電動(dòng)勢和電流，并與磁場相互作用產(chǎn)生電磁轉(zhuǎn)矩，實(shí)現(xiàn)能量變換。與單相異步電動(dòng)機(jī)相比，三相異步電動(dòng)機(jī)運(yùn)行性能好，并可節(jié)省各種材料。按轉(zhuǎn)子結(jié)構(gòu)的不同，三相異步電動(dòng)機(jī)可分為籠式和繞線式兩種?；\式轉(zhuǎn)子的異步電動(dòng)機(jī)結(jié)構(gòu)簡單、運(yùn)行可靠、重量輕、價(jià)格便宜，得到了普遍的應(yīng)用，其主要缺點(diǎn)是調(diào)速困難。繞線式三相異步電動(dòng)機(jī)的轉(zhuǎn)子和定子一樣也設(shè)置了三相繞組并通過滑環(huán)、電刷與外部變阻器連接。調(diào)節(jié)變阻器電阻可以改善電動(dòng)機(jī)的起動(dòng)性能和調(diào)節(jié)電動(dòng)機(jī)的轉(zhuǎn)速。臨沂中型電機(jī)生產(chǎn)廠家我公司將以優(yōu)良的產(chǎn)品，周到的服務(wù)與尊敬的用戶攜手并進(jìn)！</p><div

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)矩來選擇自耦變壓器副邊的不同抽頭實(shí)現(xiàn)降壓啟動(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。 </p><p> 監(jiān)視電動(dòng)機(jī)的溫度。運(yùn)行中的電動(dòng)機(jī)都要發(fā)熱，其溫升不應(yīng)超過銘牌上的允許限度。電動(dòng)機(jī)的絕大部分故障都會(huì)使它的定子電流增大，溫度升高，因此，如果發(fā)現(xiàn)電動(dòng)機(jī)的溫度超過允許值，應(yīng)立即停機(jī)檢查，查明嚴(yán)重發(fā)熱的原因，排除故障后才可以運(yùn)行。檢查電動(dòng)機(jī)的溫升常用如下方法：1)手摸。對(duì)中、小容量的電動(dòng)機(jī)，用手背觸摸電動(dòng)機(jī)的外殼，如果沒有發(fā)燙到要縮手的感覺，說明電動(dòng)機(jī)沒有過熱。如果燙得馬上縮手，難以忍受，則說明電動(dòng)機(jī)的溫度已超過了允許值。用手背而不是用手心摸電動(dòng)機(jī)的外殼，是為了防止機(jī)殼一旦帶電時(shí)，手背比手心容易自然地?cái)[脫帶電的外殼。為了防止觸電，比較好在摸機(jī)殼前，先用驗(yàn)電筆檢測一下機(jī)殼是否帶電。2)滴水。在機(jī)殼上滴幾滴水，如果看見冒熱氣而無聲音，說明電動(dòng)機(jī)沒有過熱；如果既冒熱氣，又聽到“咝咝”聲，說明電動(dòng)機(jī)已過熱，溫升已超過允許值。聯(lián)創(chuàng)電機(jī)擁有先進(jìn)的產(chǎn)品生產(chǎn)設(shè)備，雄厚的技術(shù)力量。</p><div

在電動(dòng)機(jī)運(yùn)行時(shí)，可測量其三相工作電壓和電流，看是否均衡。電壓應(yīng)基本相等，各相電流與平均值的誤差不應(yīng)超過10%，如用鉗形表測得的各相電流差值太大，則可能有匝間短路。有時(shí)需要脫開負(fù)載測量空載電流大小，一般2極約2800rpm，1/3 Ie（額定電流）；4極約1600rpm，40%左右 Ie；6極約900rpm，55% Ie。它會(huì)因極數(shù)與容量的不同而不同。另外電動(dòng)機(jī)的Y、△形接法不能搞錯(cuò)，若錯(cuò)將Y形接成△形，工作電流會(huì)增大；反之，則減小。同時(shí)，如電動(dòng)機(jī)的繞組接線錯(cuò)誤，或繞組匝數(shù)減少，舊電動(dòng)機(jī)的定轉(zhuǎn)子間氣隙過大(正常0.2-1.0mm)都會(huì)使空載電流加大，這些要點(diǎn)可以幫助我們判斷日常運(yùn)行電動(dòng)機(jī)狀況的好壞。
