導致絕緣電阻表發電機無輸出電壓或低的檢修方法

發布日期：2022-10-09 點擊率：25

                       　　導致絕緣電阻表發電機無輸出電壓或輸出的電壓很低故障的原因及其檢修方法如下：

　　1、炭刷接觸不良或炭刷磨損嚴重。

　　對于炭刷接觸不良故障，應對炭刷和整流環之間的接觸情況進行適當的調整，使兩者之間完全可靠地接觸；對于炭刷嚴重磨損故障，只有重換新的同規格的配件。

　　2、繞組斷線。

　　繞組斷線多出現在引出端處，或線圈的表面之處，可仔細地找出斷線處將其連接通即可。

　　3、電路中有斷線之處。

　　應仔細地查找斷線點，對于脫焊的焊點，應重新加焊料將其施焊牢固。
