style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> ①產生故障的原因;電路中觸頭接觸不良，使接觸電阻過大，導致壓陣増大。 </p> <p

style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;">

1)產生故障的原因;測速發電機電刷松動或接觸器觸頭接觸不良;測速發電機與電動機聯接軸松脫，使測速發電機時轉時停，導致測速負反饋時有時無;晶閘管質量不好，工作中突然失控;電動機、測速發電機勵磁繞組端頭松動。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 2)處理方法：旋緊測速發電機的電刷蓋，使之接觸良好，檢修接觸器觸頭，使之接觸良好;檢查測速發電機與電動機的連接軸，使之連接牢固;用示波器觀察晶閘管的工作情況，找出質量差的器件并進行更換;檢查電動機、測速發電機勵磁繞組的接線，務必使之牢固、可靠。 </p> <p
