三相異步電動機的缺相運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而造成的一種電動機運行狀態(tài)，三相異步電動機的繞組燒毀大多數(shù)是由于缺相運行造成的。下面，我介紹一個簡便方法針對缺相故障進行保護。一、對于星形接法電動機，由于三相交流電的失量和為零，其中性點對地電壓理論上為零，但實際上三相電壓不會平衡，總要相差幾伏電壓。當電機缺相運行時，由于定子三相電壓不平衡，中性點對地的零序電壓升高，當電機滿負荷運行時，此零序電壓可達達25～45伏。此時，可通過串接于電機中性線上的零序電壓繼電器來對電機進行保護，如圖1所示。電機正常運行時，中性點對地電壓較低，Kv不動作。，中性蘭對地電壓升高，重慶大型電機報價，重慶大型電機報價，重慶大型電機報價，使Kv動作，它的常閉觸點斷開而切斷KM線圈電源，隨即主電路斷電。二、對于定子繞組三角形接法的電機，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，如圖2所示。由于實際電路中，中性點對地總有幾伏電壓，因此可以把電壓繼電器整定到12～24伏。此外也可使用市場上的小型中間繼電器(12或24伏)來代替電壓繼電器。這樣更方便些。聯(lián)創(chuàng)電機用先進的生產(chǎn)工藝和規(guī)范的質(zhì)量管理，打造優(yōu)良的產(chǎn)品！重慶大型電機報價</p><div

iPad、手機的轉(zhuǎn)變都體現(xiàn)了人們對于電機的小型化和微型化的需求。但是要達到電機從大型化到小型化的轉(zhuǎn)變，首先要提高基礎配件的功率，并且保證基礎元件的性能和改善電機運行的原理。 <p> <br /> </p> <p> <br /> 東營三相同步電機聯(lián)創(chuàng)電機在客戶和行業(yè)中樹立了良好的企業(yè)形象。</p><div

高壓電機是指額定電壓在1000V以上電動機。常使用的是6000V和10000V電壓，由于國外的電網(wǎng)不同，也有3300V和6600V的電壓等級。高壓電機產(chǎn)生是由于電機功率與電壓和電流的乘積成正比，因此低壓電機功率增大到一定程度(如300KW/380V)電流受到導線的允許承受能力的限制就難以做大，或成本過高。需要通過提高電壓實現(xiàn)大功率輸出。高壓電機優(yōu)點是功率大，承受沖擊能力強；缺點是慣性大，啟動和制動都困難。高壓電動機可用于驅(qū)動各種不同機械之用。如壓縮機、水泵、破碎機、切削機床、運輸機械及其它設備，供礦山、機械工業(yè)、石油化工工業(yè)、發(fā)電機等各種工業(yè)中作原動機用。用以傳動鼓風機、磨煤機、軋鋼機、卷揚機的電動機應在訂貨時注明用途及技術(shù)要求，采用特殊的設計以保障可靠運行。高壓電機分為：高壓同步電機；高壓異步電機；高壓異步繞線式電動機；高壓鼠籠型電機等。 </p><p> 監(jiān)視電動機的溫度。運行中的電動機都要發(fā)熱，其溫升不應超過銘牌上的允許限度。電動機的絕大部分故障都會使它的定子電流增大，溫度升高，因此，如果發(fā)現(xiàn)電動機的溫度超過允許值，應立即停機檢查，查明嚴重發(fā)熱的原因，排除故障后才可以運行。檢查電動機的溫升常用如下方法：1)手摸。對中、小容量的電動機，用手背觸摸電動機的外殼，如果沒有發(fā)燙到要縮手的感覺，說明電動機沒有過熱。如果燙得馬上縮手，難以忍受，則說明電動機的溫度已超過了允許值。用手背而不是用手心摸電動機的外殼，是為了防止機殼一旦帶電時，手背比手心容易自然地擺脫帶電的外殼。為了防止觸電，比較好在摸機殼前，先用驗電筆檢測一下機殼是否帶電。2)滴水。在機殼上滴幾滴水，如果看見冒熱氣而無聲音，說明電動機沒有過熱；如果既冒熱氣，又聽到“咝咝”聲，說明電動機已過熱，溫升已超過允許值。聯(lián)創(chuàng)電機以質(zhì)量求生存，以信譽求發(fā)展！</p><div

吊入式機座是一個長方體的箱式結(jié)構(gòu)，機座內(nèi)部軸向有筋，用于支撐和固定定子。定子是從上方放入機座，靠定子壓圈與機座軸向筋定位并保證氣隙均勻度。再用螺栓將定子與機座緊固。機座端端板的內(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。壓入式機座大多是通過熱套方式將定子套入機座，該方式下機座與定子的同心度容易保證，但相對與吊入式機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，絕緣等級為F級，電壓等級為3KV及以上的電機都有防電暈措施。 </p> <p> ● 轉(zhuǎn)子線圈：繞線電機的轉(zhuǎn)子線圈是雙層波繞組，采用矩形銅排，絕緣等級要求為F級。 </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)過真空壓力整浸無溶劑漆后，整個定子成為一個整體，增強了其機械性和防潮能力。<span style="display:none;"></span> </p> <p> ● 轉(zhuǎn)子：鼠籠型電機一般情況下采用鑄鋁轉(zhuǎn)子，這種轉(zhuǎn)子運行可靠，并具有較好的起動性能，它可以滿壓直接起動。根據(jù)需要也可采用銅條轉(zhuǎn)子，銅條轉(zhuǎn)子電機效率相對較高，但成本也要高好多。 </p> <p> ● 軸大多焊有輻板，并經(jīng)過熱處理，具有較好的機械性能。高壓電機軸的熱處理非常關(guān)鍵，稍有不慎，會出現(xiàn)斷軸問題。聯(lián)創(chuàng)電機設備的引進更加豐富了公司的設備品種，為用戶提供了更多的選擇空間。重慶大型電機報價</p><p

同步電機，和感應電機（即異步電機）一樣是一種常用的交流電機。同步電機是電力系統(tǒng)的心臟，它是一種集旋轉(zhuǎn)與靜止、電磁變化與機械運動于一體，實現(xiàn)電能與機械能變換的元件，其動態(tài)性能十分復雜，而且其動態(tài)性能又對全電力系統(tǒng)的動態(tài)性能有極大影響。特點是：穩(wěn)態(tài)運行時，轉(zhuǎn)子的轉(zhuǎn)速和電網(wǎng)頻率之間有不變的關(guān)系n=ns=60f/p，其中f為電網(wǎng)頻率，p為電機的極對數(shù)，ns稱為同步轉(zhuǎn)速。若電網(wǎng)的頻率不變，則穩(wěn)態(tài)時同步電機的轉(zhuǎn)速恒為常數(shù)而與負載的大小無關(guān)。同步電機分為同步發(fā)電機和同步電動機。現(xiàn)代發(fā)電廠中的交流機以同步發(fā)電機為主。
