2.2發電機(ji)充(chong)電電流過(guo)大及過(guo)小故障

1主要(yao)故(gu)障現(xian)(xian)象(xiang)為發(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)怠速和低速運轉時(shi)，充電(dian)(dian)指示燈常亮，當發(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)(ji)(ji)轉速達到4000r/min時(shi)，充電(dian)(dian)指示燈熄(xi)滅。2故(gu)障原(yuan)因：出(chu)現(xian)(xian)上述癥狀一(yi)般(ban)(ban)是(shi)由于發(fa)(fa)(fa)(fa)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)充電(dian)(dian)電(dian)(dian)流(liu)過(guo)小導致(zhi)。反映(ying)到相應元器件(jian)故(gu)障上一(yi)般(ban)(ban)有(you)以(yi)下原(yuan)因，發(fa)(fa)(fa)(fa)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)的傳動(dong)(dong)帶(dai)打(da)滑(hua)嚴重，充電(dian)(dian)線路不(bu)好(hao)，發(fa)(fa)(fa)(fa)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)內(nei)部發(fa)(fa)(fa)(fa)生故(gu)障以(yi)及電(dian)(dian)壓調節(jie)器故(gu)障等。3故(gu)障檢(jian)測方法，一(yi)是(shi)檢(jian)查發(fa)(fa)(fa)(fa)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)傳動(dong)(dong)帶(dai)是(shi)否磨(mo)損，發(fa)(fa)(fa)(fa)現(xian)(xian)傳動(dong)(dong)帶(dai)沒有(you)明(ming)(ming)顯(xian)打(da)滑(hua)。然后(hou)檢(jian)查線路連接也正常，于是(shi)對發(fa)(fa)(fa)(fa)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)內(nei)部進(jin)行檢(jian)查，發(fa)(fa)(fa)(fa)現(xian)(xian)電(dian)(dian)刷有(you)明(ming)(ming)顯(xian)磨(mo)損，彈(dan)簧彈(dan)力不(bu)足。二是(shi)充電(dian)(dian)電(dian)(dian)流(liu)不(bu)穩也會導致(zhi)指示燈時(shi)亮時(shi)滅。出(chu)現(xian)(xian)這種現(xian)(xian)象(xiang)檢(jian)查發(fa)(fa)(fa)(fa)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)傳動(dong)(dong)帶(dai)和線路沒有(you)發(fa)(fa)(fa)(fa)現(xian)(xian)故(gu)障根源，就(jiu)應該考慮發(fa)(fa)(fa)(fa)電(dian)(dian)機(ji)(ji)(ji)(ji)(ji)整流(liu)二極管、電(dian)(dian)子繞組等是(shi)否斷路導致(zhi)輸(shu)出(chu)功(gong)率過(guo)低或是(shi)調節(jie)器電(dian)(dian)壓過(guo)低。應該根據實際，靈活更換相關器件(jian)，排除(chu)故(gu)障。
