山东直流电机修理检测方法：

  子昂机电维修(xiu)师(shi)傅介绍说：“这(zhei)个问(wen)题问(wen)的很好(hao)，一般情况是机壳带电、控制线(xian)(xian)路失控、绕组短路发热，致使电动(dong)机无法正(zheng)常运(yun)行等方(fang)面的故障，这(zhei)个时候，我们首先要用(yong)观察法：通过目测绕组端(duan)部及线(xian)(xian)槽内(nei)绝缘物观察有无损(sun)伤和焦黑的痕跡(ji)，如有就(jiu)是接地点(dian)。

1、用万用表低阻档检查，读数很小，则为接地。

2、根据不(bu)同的(de)等级选(xuan)用不(bu)同的(de)兆欧表(biao)测量每组电(dian)阻(zu)(zu)的(de)绝(jue)(jue)缘电(dian)阻(zu)(zu)，若(ruo)读数為零，则表(biao)示该项绕组接地(di)，但对电(dian)机绝(jue)(jue)缘受潮或因事故而(er)击穿，需(xu)依(yi)据经验判定(ding)，一般(ban)说来指针在“0”处摇摆不(bu)定(ding)时，可(ke)认为其(qi)具有一定(ding)的(de)电(dian)阻(zu)(zu)值(zhi)。

3、是试(shi)灯(deng)(deng)法：如果试(shi)灯(deng)(deng)亮(liang)，说(shuo)明绕组接地(di)(di)，若发现某处伴(ban)有(you)火(huo)花或(huo)冒烟，则(ze)该(gai)处為(wei)绕组接地(di)(di)故障点。若灯(deng)(deng)微亮(liang)则(ze)绝缘(yuan)有(you)接地(di)(di)击(ji)(ji)穿。若灯(deng)(deng)不(bu)亮(liang)，但测试(shi)棒接地(di)(di)时(shi)也出现火(huo)花，说(shuo)明绕组尚未击(ji)(ji)穿，只是严重受潮。也可用硬木(mu)在外(wai)壳的止(zhi)口边缘(yuan)轻敲(qiao)，敲(qiao)到某一处等(deng)一灭一亮(liang)时(shi)，说(shuo)明电流(liu)时(shi)通(tong)时(shi)断，则(ze)该(gai)处就是接地(di)(di)点。

4、是电(dian)(dian)流穿(chuan)烧法：用一台调压(ya)变压(ya)器，接(jie)上电(dian)(dian)源(yuan)后，接(jie)地点(dian)很快(kuai)发热，绝缘物冒(mao)烟处即為接(jie)地点(dian)。应特别註(zhu)意(yi)小型电(dian)(dian)机不得(de)超过额(e)定(ding)电(dian)(dian)流的两倍，时间不超过半分鐘;大电(dian)(dian)机為额(e)定(ding)电(dian)(dian)流的20%-50%或逐步增大电(dian)(dian)流，到接(jie)地点(dian)刚冒(mao)烟时立(li)即断(duan)电(dian)(dian)。

5、是分组淘汰(tai)法：对于接(jie)地(di)点(dian)(dian)在铁(tie)芯(xin)心里面且烧(shao)(shao)灼比(bi)较厉害(hai)，烧(shao)(shao)损的铜(tong)线与铁(tie)芯(xin)熔在一起。采用的方法是把接(jie)地(di)的一相绕(rao)组分成两半(ban)，依此类推，最后(hou)找出(chu)接(jie)地(di)点(dian)(dian)。
