玉溪干式变压器故障一般可分为机械故障和电路故障两类。机械故障主妥是运动件磨损、紧固件松动等，这些故障一般都容易检查排除。电路故障主要是玉溪干式变压器内部器件及内部电路断路、短路、搭铁或接触不良等，这些故障一般可用数字式万用表检查排除，电子调节器的技术状况可用直流可调电源进行试灯检验。汽机组每行驶一定里程时应检查传动带的传动和玉溪干式变压器的运行情况，当发现或怀疑玉溪干式变压器不发电或发电电压过高、过低时，应先检查传动带的传动、玉溪干式变压器的运行及外部电路的连接等情况，再用万用表电压档检查玉溪干式变压器的输出端电压。若机未起动时电压表指示为蓄电池端电压，机中速运转电压仍不变或不符合玉溪干式变压器额定输出电压时，说明玉溪干式变压器有故障，这时应对玉溪干式变压器进行逐项检修。检修时应按先易后难、先外后内的方法进行。结合JFW282N型充电玉溪干式变压器原理电路说明无刷充电玉溪干式变压器故障现象及其原因。(1)充电指示灯只亮不灭，或时亮时灭充电指示灯点亮主要是因为充电指示灯两端出现压差，因而可能的原因是玉溪干式变压器不发电或输出电压低，以及线路接触不良等。具体原因包括：1)线束因某种原因断路、松脱接触不良或间接电阻过大，触点氧化造成接触不良。2)定子绕组之间或绕组与玉溪干式变压器壳体之间短路。3)玉溪干式变压器励磁绕组搭铁或短路，L接线柱上的导线断路。4)整流器上的硅二极管损坏。5)调节器作用不良，晶体管元件电流表读数若随机组速变化，说明玉溪干式变压器无故障，若无变化则应依次检查其充电元件，老化、断路或稳压二极管失效。6)传动带打滑。排除方法：检查皮带张紧度是否符合标准，若不符合应调整。若损坏应予以更换或修复。(2)机运行时，充电电流过小，蓄电池亏电严重，且机运转时不充电 充电不正常的原因通常包括：1)玉溪干式变压器输出电压偏低。2)玉溪干式变压器内部整流器部分二极管损坏。3)定子绕组有一相或三相接触不良或松脱。4)传动带过松或打滑。(3)机组辆运行过程中，仪表指示有时充电，有时不充电仪表指示不正常的原因通常包括：1)传动带过松，并伴有打滑现象。2)玉溪干式变压器内装调节器工作运行不稳定。3)玉溪干式变压器接线柱各触点松动、接触不良，玉溪干式变压器内部接线松动。4)仪表自身故障。(4)玉溪干式变压器电枢(B)接线柱上导线易烧损其原因如下：1)玉溪干式变压器本身故障。电枢(B)接线柱搭铁、整流二极管击穿短路、漏电严重等导致电流大而烧损。2)线路故障。电线束被线卡子飞边磨破；线束安装位置不当，玉溪干式变压器电枢(B)接线柱上导线碰机排气歧管等。(5)玉溪干式变压器运转时有异响其主要原因有：1)传动带张紧度过大或磨损严重。2)玉溪干式变压器轴承损坏或间隙太大，运转时晃动；或玉溪干式变压器与定子相碰撞。3)玉溪干式变压器安装支架松动。
