abb調速器維修，故障分析：lkz789dhABBDCS501直流調速器維修變頻器分為 1 交---交型 輸入是交流，輸出也是交流將工頻交流電直接轉換成頻率、電壓均可控制的交流，又稱 直接式變頻器2 交—直---交型 輸入是交流，變成直流再變成交流輸出將工頻交流電通過整流變成直流電，然后再把直流電變成頻率、電壓、均可控的交流電又稱為間接變頻器。多數情況都是交直交型的變頻器。故判斷X軸發生低頻振蕩。發生振蕩的原因有： 軸位置環增益不合適。 機械部分間隙大
2變(bian)(bian)頻器的組成(cheng)由主電(dian)(dian)(dian)(dian)路(lu)和控制電(dian)(dian)(dian)(dian)路(lu)組成(cheng)主電(dian)(dian)(dian)(dian)路(lu) 由整(zheng)流(liu)(liu)器 中(zhong)間直(zhi)流(liu)(liu)環節 逆變(bian)(bian)器 組成(cheng)先(xian)看主電(dian)(dian)(dian)(dian)路(lu)原(yuan)理圖三相工頻交流(liu)(liu)電(dian)(dian)(dian)(dian) 經(jing)過(guo)VD1 ~ VD6 整(zheng)流(liu)(liu)后(hou)，正(zheng)極送入到(dao)緩(huan)沖(chong)電(dian)(dian)(dian)(dian)阻(zu)RL中(zhong)，RL的作(zuo)用是防止電(dian)(dian)(dian)(dian)流(liu)(liu)忽然(ran)變(bian)(bian)大(da)。經(jing)過(guo)一段時間電(dian)(dian)(dian)(dian)流(liu)(liu)趨于穩定后(hou)，晶閘管(guan)或繼電(dian)(dian)(dian)(dian)器的觸點會導(dao)通短路(lu)掉緩(huan)沖(chong)電(dian)(dian)(dian)(dian)阻(zu)RL ，這(zhe)(zhe)時的直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)加在了(le)(le)濾波電(dian)(dian)(dian)(dian)容CF1、CF2 上，這(zhe)(zhe)兩(liang)(liang)個(ge)(ge)電(dian)(dian)(dian)(dian)容可(ke)以(yi)把(ba)脈動的直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)波形變(bian)(bian)得平滑(hua)一些。由于一個(ge)(ge)電(dian)(dian)(dian)(dian)容的耐壓(ya)(ya)(ya)有限，所以(yi)把(ba)兩(liang)(liang)個(ge)(ge)電(dian)(dian)(dian)(dian)容串起來用，耐壓(ya)(ya)(ya)就(jiu)提高了(le)(le)一倍。又因為(wei)兩(liang)(liang)個(ge)(ge)電(dian)(dian)(dian)(dian)容的容量不一樣(yang)的話，分壓(ya)(ya)(ya)會不同，所以(yi)給兩(liang)(liang)個(ge)(ge)電(dian)(dian)(dian)(dian)容分別并聯(lian)了(le)(le)一個(ge)(ge)均壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)阻(zu)R1、R2 ，這(zhe)(zhe)樣(yang)，CF1 和CF2 上的電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)就(jiu)一樣(yang)了(le)(le)。
特(te)別是(shi)使用(yong)一(yi)(yi)定的(de)年限以(yi)后，f12一(yi)(yi)般都是(shi)勵磁通路的(de)故(gu)障(zhang)(zhang)(zhang)。F9/F10報警，主要是(shi)檢(jian)(jian)測(ce)電(dian)路出(chu)了(le)故(gu)障(zhang)(zhang)(zhang)。出(chu)現(xian)故(gu)障(zhang)(zhang)(zhang)的(de)同時，還沒啟(qi)動，面板上就檢(jian)(jian)測(ce)到(dao)不正(zheng)確(que)的(de)讀(du)數。F16/F18一(yi)(yi)般都是(shi)測(ce)速反饋的(de)問題。如果(guo)沒用(yong)測(ce)速反饋（如測(ce)速發(fa)電(dian)機檢(jian)(jian)測(ce)或編碼器檢(jian)(jian)測(ce)），就是(shi)電(dian)樞電(dian)壓發(fa)聵檢(jian)(jian)測(ce)電(dian)路出(chu)了(le)故(gu)障(zhang)(zhang)(zhang)。
abbdcs直流調速器常見報警故障有：
F12 Field Undercurrent 勵磁磁場欠流
F9 Mains Undervoltage 供電電源欠壓
F 10 Mains Overvoltage 供電電源過壓
F16 Speed Meas Fault 測速故障
F18 Overspeed 電機(ji)超(chao)速
ABB的整(zheng)流器主(zhu)電(dian)(dian)(dian)源(yuan)是不容易(yi)出問(wen)題的，只要(yao)接觸器吸合了，三(san)相(xiang)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)正常，就不應(ying)當(dang)(dang)報(bao)主(zhu)電(dian)(dian)(dian)源(yuan)欠壓(ya)。然而事實并沒有這么簡單，這要(yao)從(cong)它(ta)的電(dian)(dian)(dian)壓(ya)檢測電(dian)(dian)(dian)路(lu)(lu)說起。三(san)相(xiang)主(zhu)線路(lu)(lu)經過銅排(pai)供給可控硅后(hou)，還有三(san)根小線借到(dao)電(dian)(dian)(dian)源(yuan)板上(shang)，經過保險后(hou)供給勵磁整(zheng)流電(dian)(dian)(dian)路(lu)(lu)，電(dian)(dian)(dian)壓(ya)檢測電(dian)(dian)(dian)路(lu)(lu)也是從(cong)保險后(hou)取樣(yang)的，也就是說取樣(yang)電(dian)(dian)(dian)路(lu)(lu)、檢測元件(jian)以(yi)及勵磁短路(lu)(lu)引起的保險融斷都能引發F9故(gu)障(zhang)，所以(yi)當(dang)(dang)出現這個故(gu)障(zhang)的時候，我們不能僅僅從(cong)電(dian)(dian)(dian)壓(ya)入手(shou)，不然很難找到(dao)真正的故(gu)障(zhang)點。
