電機電流過高作為常見導致電機故障的原因，山東電機生產廠家提醒使用企業，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。

今天山東省(sheng)馬達制作制造廠為大家盤點交流接(jie)觸器直(zhi)流電過高的愿意(yi)。

1、交流(liu)(liu)(liu)(liu)主(zhu)機電(dian)(dian)源(yuan)模塊(kuai)(kuai)(kuai)線(xian)電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)直流(liu)(liu)(liu)(liu)電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)過高當交流(liu)(liu)(liu)(liu)主(zhu)機電(dian)(dian)源(yuan)模塊(kuai)(kuai)(kuai)線(xian)電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)直流(liu)(liu)(liu)(liu)電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)過高時，自(zi)因素反自(zi)動勢、磁(ci)(ci)(ci)通(tong)及磁(ci)(ci)(ci)通(tong)導(dao)熱(re)系數均無常(chang)的(de)意思變大(da)。在鐵耗費(fei)的(de)大(da)小不一與(yu)磁(ci)(ci)(ci)通(tong)導(dao)熱(re)系數每(mei)平方(fang)米不成比(bi)例(li)，則鐵耗費(fei)加大(da)，引致鐵心電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)不穩(wen)。而磁(ci)(ci)(ci)通(tong)加大(da)，又(you)因受勵磁(ci)(ci)(ci)電(dian)(dian)直流(liu)(liu)(liu)(liu)電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)信噪比(bi)快速(su)加大(da)，引致定子線(xian)圈(quan)銅損變大(da)，使線(xian)圈(quan)電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)不穩(wen)。所(suo)以，交流(liu)(liu)(liu)(liu)主(zhu)機電(dian)(dian)源(yuan)模塊(kuai)(kuai)(kuai)線(xian)電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)直流(liu)(liu)(liu)(liu)電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)不超自(zi)因素的(de)額定的(de)線(xian)電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)直流(liu)(liu)(liu)(liu)電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)時，會使自(zi)因素電(dian)(dian)流(liu)(liu)(liu)(liu)值(zhi)(zhi)(zhi)(zhi)不穩(wen)。

2、主(zhu)(zhu)機(ji)(ji)供電(dian)工作線電(dian)壓(ya)過低(di)主(zhu)(zhu)機(ji)(ji)供電(dian)工作線電(dian)壓(ya)過低(di)時，若自主(zhu)(zhu)觀因素(su)的(de)(de)電(dian)磁爐傳動比(bi)確保保持不變(bian)，磁通將(jiang)消減，馬達(da)定(ding)子和(he)(he)轉子交(jiao)流(liu)電(dian)相對擴大，定(ding)子交(jiao)流(liu)電(dian)中過載(zai)主(zhu)(zhu)機(ji)(ji)供電(dian)凈重逐(zhu)漸多(duo)，形成繞線的(de)(de)銅損耗量(liang)擴大，讓定(ding)、馬達(da)定(ding)子和(he)(he)轉子繞阻發熱。

3、外接電源電壓值(zhi)不合適稱

當(dang)交流電源(yuan)線(xian)一(yi)(yi)相(xiang)斷路、穩定(ding)絲(si)一(yi)(yi)相(xiang)擊穿，或閘刀啟動時機(ji)(ji)器(qi)角(jiao)頭燒傷倒致(zhi)(zhi)一(yi)(yi)相(xiang)不了，都將(jiang)產生三相(xiang)四線(xian)制電源(yuan)電動四輪(lun)機(ji)(ji)走兩相(xiang)電，倒致(zhi)(zhi)進行的二相(xiang)線(xian)圈利用大功(gong)率擦肩(jian)而過熱，及至焚毀。故而，針對(dui)于(yu)三相(xiang)四線(xian)制電源(yuan)電機(ji)(ji)馬達一(yi)(yi)樣(yang)不舒服用擊穿器(qi)進行保(bao)護英文。

4、三相(xiang)電(dian)(dian)(dian)源四(si)線制(zhi)電(dian)(dian)(dian)原(yuan)電(dian)(dian)(dian)原(yuan)不(bu)發展當三相(xiang)電(dian)(dian)(dian)源四(si)線制(zhi)電(dian)(dian)(dian)原(yuan)電(dian)(dian)(dian)原(yuan)不(bu)發展時，會使電(dian)(dian)(dian)動式機的三相(xiang)電(dian)(dian)(dian)源四(si)線制(zhi)電(dian)(dian)(dian)原(yuan)直流(liu)電(dian)(dian)(dian)不(bu)發展，引(yin)致電(dian)(dian)(dian)機繞線電(dian)(dian)(dian)壓不(bu)穩(wen)。

河南發(fa)電(dian)(dian)機(ji)生孩子(zi)廠(chang)家直(zhi)銷提醒，由上述可(ke)(ke)見(jian)，當電(dian)(dian)動(dong)機(ji)過熱時，應首(shou)先考慮(lv)電(dian)(dian)源方(fang)面的原因（軟啟動(dong)、變頻器(qi)、伺服驅動(dong)器(qi)亦可(ke)(ke)看作是(shi)電(dian)(dian)源）。確認電(dian)(dian)源方(fang)面無問(wen)題后，再(zai)去考慮(lv)其(qi)他方(fang)面因素。
