試燈(deng)法。如果試燈(deng)亮(liang)，說(shuo)(shuo)明繞組接(jie)(jie)(jie)(jie)(jie)地(di)(di)，若發(fa)現(xian)某處(chu)(chu)伴有(you)(you)火(huo)花(hua)或冒(mao)煙，則(ze)該(gai)處(chu)(chu)為繞組接(jie)(jie)(jie)(jie)(jie)地(di)(di)故障點(dian)(dian)。若燈(deng)微亮(liang)則(ze)絕緣有(you)(you)接(jie)(jie)(jie)(jie)(jie)地(di)(di)擊穿。若燈(deng)不亮(liang)，但測試棒(bang)接(jie)(jie)(jie)(jie)(jie)地(di)(di)時(shi)(shi)也出現(xian)火(huo)花(hua)，說(shuo)(shuo)明繞組尚未擊穿，只(zhi)是(shi)嚴重受潮。也可用(yong)硬木(mu)在外殼的止口邊緣輕敲，敲到(dao)(dao)某一處(chu)(chu)等(deng)一滅一亮(liang)時(shi)(shi)，說(shuo)(shuo)明電(dian)(dian)(dian)(dian)(dian)流(liu)時(shi)(shi)通(tong)時(shi)(shi)斷，則(ze)該(gai)處(chu)(chu)就是(shi)接(jie)(jie)(jie)(jie)(jie)地(di)(di)點(dian)(dian)。（5）電(dian)(dian)(dian)(dian)(dian)流(liu)穿燒法。用(yong)一臺調壓(ya)變(bian)壓(ya)器，接(jie)(jie)(jie)(jie)(jie)上電(dian)(dian)(dian)(dian)(dian)源后，接(jie)(jie)(jie)(jie)(jie)地(di)(di)點(dian)(dian)很快發(fa)熱，絕緣物冒(mao)煙處(chu)(chu)即(ji)為接(jie)(jie)(jie)(jie)(jie)地(di)(di)點(dian)(dian)。應(ying)特別(bie)注意小型電(dian)(dian)(dian)(dian)(dian)機不得超(chao)過額定(ding)電(dian)(dian)(dian)(dian)(dian)流(liu)的兩倍(bei)，廈門(men)高(gao)(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)機維修，時(shi)(shi)間不超(chao)過半(ban)(ban)分(fen)鐘；大電(dian)(dian)(dian)(dian)(dian)機為額定(ding)電(dian)(dian)(dian)(dian)(dian)流(liu)的20%-50%或逐步增(zeng)大電(dian)(dian)(dian)(dian)(dian)流(liu)，寧德高(gao)(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)機，到(dao)(dao)接(jie)(jie)(jie)(jie)(jie)地(di)(di)點(dian)(dian)剛冒(mao)煙時(shi)(shi)立(li)即(ji)斷電(dian)(dian)(dian)(dian)(dian)。（6）分(fen)組淘汰法。對于接(jie)(jie)(jie)(jie)(jie)地(di)(di)點(dian)(dian)在鐵芯心里面且燒灼比較厲害，廈門(men)高(gao)(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)機保養，燒損的銅線與鐵芯熔在一起。采用(yong)的方(fang)法是(shi)把接(jie)(jie)(jie)(jie)(jie)地(di)(di)的一相(xiang)繞組分(fen)成兩半(ban)(ban)，依此類推，后找出接(jie)(jie)(jie)(jie)(jie)地(di)(di)點(dian)(dian)。

廈門重(zhong)力通機電設(she)備有限公司取得防爆電機安裝、修理(li)資格證書，承接國(guo)內、外大中型(xing)交流、直流、高低壓電機，以及各類旋(xuan)轉傳動類設(she)備維修和(he)保養。

絕緣情況(kuang)的(de)(de)(de)檢查(cha)。 絕緣材料 的(de)(de)(de)絕緣能力因干(gan)燥程度不同而異，所以(yi)檢查(cha)電(dian)(dian)(dian)(dian)機(ji)(ji) 繞組的(de)(de)(de)干(gan)燥是非常(chang)重(zhong)要(yao)(yao)的(de)(de)(de)。 電(dian)(dian)(dian)(dian)機(ji)(ji)工(gong)作環境潮濕、 工(gong)作間有腐蝕性氣體等因素存在(zai)，廈門重(zhong)力通，都會破壞電(dian)(dian)(dian)(dian)絕緣。常(chang)見的(de)(de)(de)是 繞組接(jie)地(di)故障 ，即絕緣損壞，使帶電(dian)(dian)(dian)(dian)部(bu)分(fen)與機(ji)(ji)殼等不應(ying)帶電(dian)(dian)(dian)(dian)的(de)(de)(de)金(jin)屬部(bu)分(fen)相碰， 發生這(zhe)種故障， 不僅(jin)影響電(dian)(dian)(dian)(dian)機(ji)(ji)正(zheng)常(chang)工(gong)作， 還會危及 人身安全(quan) 。所以(yi)，電(dian)(dian)(dian)(dian)機(ji)(ji)在(zai)使用中，應(ying)經常(chang)檢查(cha) 絕緣電(dian)(dian)(dian)(dian)阻 ，還要(yao)(yao)注意查(cha)看電(dian)(dian)(dian)(dian)機(ji)(ji)機(ji)(ji)殼接(jie)地(di)是否可靠。
