柴(chai)油發電(dian)機充電(dian)電(dian)流過(guo)小的現象，你遇到過(guo)嗎？
柴(chai)油(you)(you)發電(dian)(dian)(dian)(dian)(dian)機(ji)在(zai)不斷(duan)的(de)使(shi)用中難免(mian)會出現(xian)這樣或者那樣的(de)故(gu)障，由柴(chai)油(you)(you)發電(dian)(dian)(dian)(dian)(dian)機(ji)技(ji)(ji)術人(ren)(ren)員對機(ji)組(zu)進行檢修(xiu)，故(gu)障排除后方可(ke)再(zai)次投入(ru)運行，比如說(shuo)在(zai)使(shi)用柴(chai)油(you)(you)發電(dian)(dian)(dian)(dian)(dian)機(ji)組(zu)時(shi)(shi)，當機(ji)組(zu)起動至額定(ding)轉速后，有時(shi)(shi)會碰(peng)到發電(dian)(dian)(dian)(dian)(dian)機(ji)充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流過(guo)小，對柴(chai)油(you)(you)發電(dian)(dian)(dian)(dian)(dian)機(ji)技(ji)(ji)術人(ren)(ren)員來(lai)說(shuo)，這種故(gu)障是(shi)小問題，解決起來(lai)就是(shi)小菜(cai)一碟，但(dan)是(shi)對普通操作人(ren)(ren)員來(lai)還是(shi)比較復雜(za)的(de)，那么解決的(de)辦(ban)法是(shi)什么呢?柴(chai)油(you)(you)發電(dian)(dian)(dian)(dian)(dian)機(ji)充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流過(guo)小這種故(gu)障一般是(shi)由于個別硅二極管引線脫焊斷(duan)開或電(dian)(dian)(dian)(dian)(dian)刷與滑環(huan)接(jie)觸不良所造成的(de)，具體原(yuan)因如下：
1、皮帶打滑(hua)。
2、調節(jie)(jie)(jie)器電(dian)(dian)(dian)(dian)壓(ya)偏低。電(dian)(dian)(dian)(dian)壓(ya)調節(jie)(jie)(jie)器的功(gong)能(neng)：電(dian)(dian)(dian)(dian)壓(ya)調節(jie)(jie)(jie)器通過對(dui)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)機交流(liu)(liu)勵磁(ci)機勵磁(ci)電(dian)(dian)(dian)(dian)流(liu)(liu)的控制(zhi)，實現對(dui)輸(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)的自動調節(jie)(jie)(jie)。發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)壓(ya)調節(jie)(jie)(jie)器可滿足普通60/50Hz及(ji)中頻400Hz單機或并(bing)列運行的發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)機使用。通過控制(zhi)勵磁(ci)分(fen)流(liu)(liu)電(dian)(dian)(dian)(dian)流(liu)(liu)的大小，從而改變勵磁(ci)電(dian)(dian)(dian)(dian)流(liu)(liu)，達(da)到調節(jie)(jie)(jie)發(fa)(fa)(fa)電(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)壓(ya)的目的。
3、柴油發電(dian)(dian)機磁(ci)場線(xian)搭(da)(da)鐵(tie)或(huo)磁(ci)場線(xian)圈(quan)局部(bu)搭(da)(da)鐵(tie)短(duan)(duan)路等。磁(ci)場線(xian)搭(da)(da)鐵(tie)或(huo)磁(ci)場線(xian)圈(quan)局部(bu)搭(da)(da)鐵(tie)短(duan)(duan)路，則導致發電(dian)(dian)機不勵磁(ci)，就不發電(dian)(dian)或(huo)電(dian)(dian)流過(guo)小。用萬用表(biao)(biao)測(ce)(ce)量發電(dian)(dian)機磁(ci)專場接線(xian)柱和接地接線(xian)柱之間的電(dian)(dian)阻止值就可(ke)知道，若(ruo)測(ce)(ce)得的電(dian)(dian)阻值與規定的電(dian)(dian)阻值很(hen)接近(jin)，說(shuo)明(ming)是正常(chang)的，如果(guo)電(dian)(dian)阻測(ce)(ce)不出來(lai)，萬用表(biao)(biao)沒有指示(shi)，則說(shuo)明(ming)勵磁(ci)回路不通。
4、柴油發(fa)電機(ji)硅二極管引線脫焊斷開，使(shi)電樞線圈一相或二相斷路。
5、電(dian)(dian)刷與滑(hua)環接觸(chu)不良(滑(hua)環上(shang)有臟物，碳刷磨損(sun)太(tai)大，彈簧(huang)壓力不足等)，接觸(chu)電(dian)(dian)阻較大，使激磁電(dian)(dian)流變小。
柴油(you)發電機充電電流過小的解(jie)決方法：
1、對柴油發(fa)電機電刷(shua)與滑環(huan)接觸情況進行檢查，查看是否發(fa)現異(yi)常(chang)；
2、用萬用表直流(liu)電壓擋測量調(diao)節器(qi)輸出(chu)電壓，查看輸出(chu)電壓是否高或低于正常(chang)范圍；
  3、用萬用表直流電(dian)(dian)壓(ya)擋測量發(fa)電(dian)(dian)機輸出(chu)(chu)電(dian)(dian)壓(ya)，發(fa)現輸出(chu)(chu)電(dian)(dian)壓(ya)為5V(測量時要斷開調節器與蓄電(dian)(dian)池(chi)的(de)接線(xian))，這證明故障(zhang)在充(chong)電(dian)(dian)發(fa)電(dian)(dian)機上。
  4、在測量二(er)極管時(shi)，發現有4個二(er)極管燒(shao)壞。更換二(er)極管，對柴油發電機進行裝配，然(ran)后起動柴油發電機至1300r/min時(shi)，儀表盤上(shang)的充電電流(liu)表顯示為(wei)15A，說明柴油發電機充電正常。
