举例

    (1) 一台CT 18.5kW变频器上电跳“Uu"。

    分析与维修:经检查这台变频器的整流桥充电电阻都是好的，但是上电后没有听到接触器动作，因为这台变频器的充电回路不是利用可控硅而是靠接触器的吸合来完成充电过程的，因此认为故障可能出在接触器或控制回路以及电源部分，拆掉接触器单独加24V直流电接触器工作正常。继而检查24V直流电源，经仔细检查该电压是经过LM7824稳压管稳压后输出的，测量该稳压管已损坏，找一新品更换后上电工作正常。：张亮（工程师）    专线：

    (2) 一台DANFOSS VLT5004变频器，上电显示正常，但是加负载后跳“DC LINK UNDERVOLT"(直流回路电压低)。

    分析与维修:这台变频器从现象上看比较特别，但是你如果仔细分析一下问题也就不是那么复杂，该变频器同样也是通过充电回路，接触器来完成充电过程的，上电时没有发现任何异常现象，估计是加负载时直流回路的电压下降所引起，而直流回路的电压又是通过整流桥全波整流,然后由电容平波后提供的，所以应着重检查整流桥，经测量发现该整流桥有一路桥臂开路，更换新品后问题解决。
