舉例
(1) 一臺CT 18.5kW變頻器上電跳“Uu"。
分析與維修:經(jīng)檢查這臺變頻器的整流橋充電電阻都是好的，但是上電后沒有聽到接觸器動作，因為這臺變頻器的充電回路不是利用可控硅而是靠接觸器的吸合來完成充電過程的，因此認為故障可能出在接觸器或控制回路以及電源部分，拆掉接觸器單獨加24V直流電接觸器工作正常。繼而檢查24V直流電源，經(jīng)仔細檢查該電壓是經(jīng)過LM7824穩(wěn)壓管穩(wěn)壓后輸出的，測量該穩(wěn)壓管已損壞，找一新品更換后上電工作正常。：張亮（工程師） 專線：

(2) 一臺DANFOSS VLT5004變頻器，上電顯示正常，但是加負載后跳“DC LINK UNDERVOLT"(直流回路電壓低)。
分析與維修:這臺變頻器從現(xiàn)象上看比較特別，但是你如果仔細分析一下問題也就不是那么復雜，該變頻器同樣也是通過充電回路，接觸器來完成充電過程的，上電時沒有發(fā)現(xiàn)任何異常現(xiàn)象，估計是加負載時直流回路的電壓下降所引起，而直流回路的電壓又是通過整流橋全波整流,然后由電容平波后提供的，所以應著重檢查整流橋，經(jīng)測量發(fā)現(xiàn)該整流橋有一路橋臂開路，更換新品后問題解決。
