對于交流電機，額定電壓在1000V及以上的為高壓電機；低于1000V的為低壓電機(有些資料中的界限是1140V)。對于直流電機，額定電壓在1500V及以上的為高壓電機；低于1500V的為低壓電機。那么，高壓電機和低壓電機相比有哪些優(yōu)缺點：額定電壓不一樣，啟動和工作電流不一樣，電壓越高，電流越??；電機的絕緣和耐壓也不一樣，電機繞組的導(dǎo)線也一樣，同樣功率的電機，高電壓的電機導(dǎo)線比低電壓的要少，使用的電纜也不一樣。 </p> <p> 一、線圈的絕緣材料有所區(qū)別，低壓電機，線圈主要采用漆包線或其他簡單的絕緣，如復(fù)合紙，高壓電機的絕緣通常采用多層結(jié)構(gòu)，如粉云母帶，結(jié)構(gòu)更復(fù)雜，耐壓程度更高。 </p> <p> 二、散熱結(jié)構(gòu)上的區(qū)別，低壓電機主要采用同軸風扇直吹散熱，高壓電機大多數(shù)帶有**的散熱器，通常有兩種風扇，一組內(nèi)循環(huán)風扇，一組外循環(huán)風扇，兩組風扇同時運轉(zhuǎn)，在散熱器上進行熱交換將熱量排出電機外面。 </p> <p> 三，軸承結(jié)構(gòu)不同，低壓電動機通常前后各有一組軸承，而高壓電動機，因為負載較重，通常軸伸端會有兩組軸承，非軸伸端的軸承數(shù)量根據(jù)負載情況而定，而特別大型的電動機會采用滑動軸承。 </p> <p> <br /> 萊蕪三相異步電機維修聯(lián)創(chuàng)電機的行業(yè)影響力逐年提升。</p> <span

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(dǎo)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(shè)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(yīng)在訂貨時注明用途及技術(shù)要求，采用特殊的設(shè)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> 三相異步電機（Triple-phaseasynchronousmotor）是感應(yīng)電動機的一種，是靠同時接入380V三相交流電流（相位差120度）供電的一類電動機，由于三相異步電動機的轉(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機。三相異步電動機轉(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運動而產(chǎn)生電動勢和電流，并與磁場相互作用產(chǎn)生電磁轉(zhuǎn)矩，實現(xiàn)能量變換。與單相異步電動機相比，三相異步電動機運行性能好，并可節(jié)省各種材料。按轉(zhuǎn)子結(jié)構(gòu)的不同，三相異步電動機可分為籠式和繞線式兩種?；\式轉(zhuǎn)子的異步電動機結(jié)構(gòu)簡單、運行可靠、重量輕、價格便宜，得到了普遍的應(yīng)用，其主要缺點是調(diào)速困難。繞線式三相異步電動機的轉(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機的起動性能和調(diào)節(jié)電動機的轉(zhuǎn)速。聯(lián)創(chuàng)電機熱忱歡迎新老客戶惠顧。</p><div
