電機電流過高作為常見導致電機故障的原因，變頻電機廠家提醒使用企業，當電機出現電流過高的故障，應及時停機檢查，避免電機出現燒毀的故障。今天蘭州盛華變頻式直流無刷電機廠整理數據，為大家盤點交流接觸器直流電壓過高情況。

一、電問題

1、電(dian)(dian)原相(xiang)電(dian)(dian)流降過(guo)高當電(dian)(dian)原相(xiang)電(dian)(dian)流降過(guo)高時，智能機(ji)反智能勢、磁(ci)(ci)通及磁(ci)(ci)通相(xiang)對體(ti)積(ji)密(mi)度均進而不(bu)斷增強(qiang)。基于(yu)鐵(tie)不(bu)足率的(de)(de)面積(ji)大(da)小(xiao)與磁(ci)(ci)通相(xiang)對體(ti)積(ji)密(mi)度平(ping)方和不(bu)成(cheng)比例，則鐵(tie)不(bu)足率加大(da)，以至于(yu)鐵(tie)心cpu起(qi)熱(re)。而磁(ci)(ci)通加大(da)，又發生(sheng)的(de)(de)激磁(ci)(ci)電(dian)(dian)流值權重(zhong)陡然加大(da)，發生(sheng)定子線圈銅(tong)損(sun)不(bu)斷增強(qiang)，使線圈cpu起(qi)熱(re)。由此，電(dian)(dian)原相(xiang)電(dian)(dian)流降已超智能機(ji)的(de)(de)額定的(de)(de)相(xiang)電(dian)(dian)流降時，會使智能機(ji)cpu起(qi)熱(re)。

2、電(dian)(dian)(dian)源(yuan)(yuan)開(kai)(kai)關(guan)(guan)開(kai)(kai)關(guan)(guan)開(kai)(kai)關(guan)(guan)額(e)定(ding)電(dian)(dian)(dian)阻(zu)值過低電(dian)(dian)(dian)源(yuan)(yuan)開(kai)(kai)關(guan)(guan)開(kai)(kai)關(guan)(guan)開(kai)(kai)關(guan)(guan)額(e)定(ding)電(dian)(dian)(dian)阻(zu)值過低時，若(ruo)電(dian)(dian)(dian)動(dong)三(san)輪機的渦(wo)流(liu)電(dian)(dian)(dian)動(dong)機扭矩保證一(yi)致(zhi)，磁通將影響，旋轉葉交流(liu)電(dian)(dian)(dian)合理提升，定(ding)子交流(liu)電(dian)(dian)(dian)中負載(zai)電(dian)(dian)(dian)阻(zu)電(dian)(dian)(dian)源(yuan)(yuan)開(kai)(kai)關(guan)(guan)開(kai)(kai)關(guan)(guan)開(kai)(kai)關(guan)(guan)參量不斷(duan)多，導致(zhi)繞線的銅消耗的資金提升，促使定(ding)、旋轉葉電(dian)(dian)(dian)機定(ding)子太燙。

3、電源適(shi)配器(qi)額定(ding)電壓不合適(shi)稱

當交流(liu)(liu)電源(yuan)線一相(xiang)(xiang)斷路(lu)、人壽保險絲一相(xiang)(xiang)短路(lu)機(ji)制，或閘刀啟動主設備角頭燒傷原因(yin)分析一相(xiang)(xiang)不進去，都將(jiang)從而(er)造成380V電動式機(ji)走二相(xiang)(xiang)，原因(yin)分析啟動的二相(xiang)(xiang)繞(rao)阻能夠 大瞬時(shi)電流(liu)(liu)即(ji)逝熱，及(ji)至(zhi)損毀。從而(er)，相(xiang)(xiang)對380V伺(si)服電機(ji)基本上(shang)痛感用(yong)短路(lu)機(ji)制器做保護性。

4、三相(xiang)電(dian)(dian)機四(si)線電(dian)(dian)電(dian)(dian)不和平當三相(xiang)電(dian)(dian)機四(si)線電(dian)(dian)電(dian)(dian)不和平時，會使電(dian)(dian)動伸縮(suo)機的三相(xiang)電(dian)(dian)機四(si)線電(dian)(dian)感應電(dian)(dian)流不和平，吸引電(dian)(dian)機定子cpu過熱。

二、同(tong)步電機負債難(nan)題(ti)

阻(zu)抗多方面(mian)使智能機起(qi)熱原由有下列各種：

1、直流電(dian)(dian)驅動力電(dian)(dian)機負載操(cao)作

當裝(zhuang)備不(bu)搭(da)配，電動(dong)式(shi)(shi)機(ji)的(de)(de)短路電流功效不(bu)低于電動(dong)式(shi)(shi)機(ji)的(de)(de)額定(ding)功效時，則電動(dong)式(shi)(shi)機(ji)長久的(de)(de)過載保護自動(dong)運行（即小馬拉(la)大貨車(che)），會造成電動(dong)式(shi)(shi)機(ji)溫度過高。

2、拖動的機械設備(bei)負(fu)載電阻事情一(yi)高一(yi)低常

機械性固(gu)然生(sheng)活配套，但所拖(tuo)動的(de)機械性載荷做工作不對常，程序(xu)運(yun)行時載荷時大時小，電(dian)動三輪(lun)機過(guo)載保(bao)護(hu)而發高燒。

3、拖動的自動化(hua)有故障率

當被拖動(dong)的機(ji)械設備制造有(you)錯誤代碼，翻轉不輕松或被卡住，都將使電(dian)動(dong)機(ji)電(dian)機(ji)負載(zai)，有(you)電(dian)動(dong)機(ji)線圈溫度過(guo)熱。

三、變頻(pin)電動機客(ke)觀存在(zai)困難

1、智(zhi)能機繞阻(zu)斷路

當(dang)智(zhi)能機(ji)電(dian)機(ji)定(ding)(ding)子中(zhong)(zhong)含(han)一相(xiang)電(dian)機(ji)定(ding)(ding)子斷路(lu)(lu)，或串連支路(lu)(lu)中(zhong)(zhong)含(han)一次支路(lu)(lu)斷路(lu)(lu)時(shi)，都將(jiang)產生三相(xiang)電(dian)源電(dian)流值不發展，使(shi)智(zhi)能機(ji)電(dian)壓不穩。

2、電動(dong)四輪(lun)機電機繞線擊(ji)穿

當直流電(dian)(dian)因素(su)電(dian)(dian)機定子(zi)出顯跳閘出現問題時，跳閘事業(ye)直流電(dian)(dian)比很(hen)正常事業(ye)事業(ye)直流電(dian)(dian)并不大，使電(dian)(dian)機定子(zi)銅(tong)損耗費提高，導至電(dian)(dian)機定子(zi)過高，恐怕(pa)燒(shao)壞。

3、電動伸縮機(ji)星角接法內部(bu)錯誤

當半圓(yuan)型形(xing)接(jie)(jie)法電(dian)(dian)(dian)動(dong)三(san)(san)輪機(ji)(ji)錯接(jie)(jie)成(cheng)星形(xing)時(shi)，電(dian)(dian)(dian)動(dong)三(san)(san)輪機(ji)(ji)仍帶滿(man)負債(zhai)運營，定(ding)子(zi)電(dian)(dian)(dian)機(ji)(ji)定(ding)子(zi)流(liu)下(xia)的(de)(de)直流(liu)電(dian)(dian)(dian)壓要已超額定(ding)負載(zai)直流(liu)電(dian)(dian)(dian)壓，乃至于(yu)引(yin)發(fa)(fa)電(dian)(dian)(dian)動(dong)三(san)(san)輪機(ji)(ji)自愿(yuan)車停，若停轉事件稍長又未切斷所有設(she)備的(de)(de)電(dian)(dian)(dian)源(yuan)適配器(qi)電(dian)(dian)(dian)源(yuan)適配器(qi)，電(dian)(dian)(dian)機(ji)(ji)定(ding)子(zi)實際上造(zao)成(cheng) 發(fa)(fa)熱(re)，還將毀壞(huai)。當星形(xing)接(jie)(jie)連(lian)的(de)(de)電(dian)(dian)(dian)動(dong)三(san)(san)輪機(ji)(ji)錯接(jie)(jie)成(cheng)半圓(yuan)型形(xing)，或指導(dao)意(yi)見個磁圈組串成(cheng)小條支路的(de)(de)電(dian)(dian)(dian)動(dong)三(san)(san)輪機(ji)(ji)錯接(jie)(jie)成(cheng)二支路并接(jie)(jie)，都將使(shi)電(dian)(dian)(dian)機(ji)(ji)定(ding)子(zi)與鐵(tie)心發(fa)(fa)熱(re)，造(zao)成(cheng) 時(shi)將毀壞(huai)電(dian)(dian)(dian)機(ji)(ji)定(ding)子(zi)。

4、智能機電機轉子接法錯誤操作

當一(yi)位次(ci)級(ji)(ji)電(dian)(dian)感(gan)線(xian)(xian)(xian)圈(quan)、次(ci)級(ji)(ji)電(dian)(dian)感(gan)線(xian)(xian)(xian)圈(quan)組或一(yi)相線(xian)(xian)(xian)圈(quan)接反時，都在以至(zhi)于三相電(dian)(dian)機(ji)電(dian)(dian)流值比較(jiao)嚴重不(bu)動平衡，而使線(xian)(xian)(xian)圈(quan)溫度過熱。

5、直流電傾向的廠家(jia)洛(luo)天依(yi)

當直流電行(xing)為軸變形、裝配圖不易、軸承套有壞毛病等(deng)，均會使直流電行(xing)為交流電增大，自動上(shang)鏈的效率降低等(deng)不良情況的發生，銅耗(hao)(hao)費及機戒靜(jing)摩擦力耗(hao)(hao)費新增，使直流電行(xing)為溫度過高。
