山東電機生產廠家提醒，對于低壓電機，會按照功率進行分段處理，例如基本系列電機按照3kW分界，不高(gao)(gao)達3kW按(an)星接(jie)，同一(yi)按(an)角接(jie)，而(er)針對于那些直流變頻(pin)主軸(zhou)變頻(pin)電(dian)(dian)動機，則按(an)45kW分界，不高(gao)(gao)達45kW按(an)星接(jie)，同一(yi)按(an)角接(jie)；而(er)針對于那些塔吊(diao)及化工主軸(zhou)變頻(pin)電(dian)(dian)動機則如果(guo)根據星接(jie)較多，大規格尺寸塔吊(diao)主軸(zhou)變頻(pin)電(dian)(dian)動機也會分為角接(jie)。

那(nei)么(me)你(ni)知道為什么(me)髙壓電機馬達通常(chang)運用星型(xing)接(jie)法嗎？

髙壓三(san)(san)相(xiang)(xiang)異步(bu)同步(bu)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)基本均(jun)是(shi)星型連接線(xian)具體(ti)方法，基本原(yuan)則是(shi)防止(zhi)三(san)(san)相(xiang)(xiang)異步(bu)同步(bu)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)線(xian)圈承受壓力較高的額定(ding)端電(dian)(dian)(dian)(dian)(dian)(dian)壓降(jiang)(jiang)。星形接法中，線(xian)端電(dian)(dian)(dian)(dian)(dian)(dian)壓降(jiang)(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)值(zhi)相(xiang)(xiang)當于相(xiang)(xiang)端電(dian)(dian)(dian)(dian)(dian)(dian)壓降(jiang)(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)值(zhi)，線(xian)額定(ding)端電(dian)(dian)(dian)(dian)(dian)(dian)壓降(jiang)(jiang)是(shi)相(xiang)(xiang)額定(ding)端電(dian)(dian)(dian)(dian)(dian)(dian)壓降(jiang)(jiang)的根號3倍(bei)（三(san)(san)邊形形接法中，線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)阻值(zhi)相(xiang)(xiang)約(yue)等(deng)于相(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)阻值(zhi)而線(xian)瞬(shun)時(shi)(shi)瞬(shun)時(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)相(xiang)(xiang)約(yue)等(deng)于相(xiang)(xiang)瞬(shun)時(shi)(shi)瞬(shun)時(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的√3倍(bei)），如此(ci)伺服電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)定(ding)子(zi)所必(bi)須(xu)的電(dian)(dian)(dian)(dian)(dian)(dian)阻值(zhi)相(xiang)(xiang)應較低。

在高(gao)(gao)壓(ya)變壓(ya)器發(fa)高(gao)(gao)壓(ya)三相異(yi)步電(dian)機中，工作電(dian)流(liu)都較小，而對發(fa)高(gao)(gao)壓(ya)三相異(yi)步電(dian)機的耐壓(ya)電(dian)阻等級保護想(xiang)要較高(gao)(gao)，因為應(ying)用星形接法發(fa)高(gao)(gao)壓(ya)三相異(yi)步電(dian)機的耐壓(ya)電(dian)阻良好辦理(li)，也更生(sheng)活些(xie)。
