西門子整流回饋單元報F033十年技術維修診斷：如果電網沒有出現問題，整流側不會爆快熔的，爆快熔說明整流回饋出現問題了：或者觸發出了故障，量一下硅有沒有問題。
空載能夠運行說明不了問題，因為變頻器輸出的都是無功電流，不需要電網輸入多大電流，電源缺相也能運行，重載和高速會造成直流電壓降；
逆變(bian)(bian)器(qi)報過壓，可能回饋不工作(zuo)或者逆變(bian)(bian)失敗(bai)；估計整流(liu)缺(que)臂或者缺(que)相了，已經換了整流(liu)/回饋單元(yuan)，檢查一下供電(dian)(dian)設備吧。N4集成(cheng)塊UC3844AN各引(yin)腳電(dian)(dian)壓數據如表3所示(shi)。N7 集成(cheng)塊L7824各引(yin)腳電(dian)(dian)壓數據如表4所示(shi)。
