更(geng)換貼片電(dian)容就行了。負(fu)載換相(xiang)式(shi)電(dian)流源型(xing)中壓(ya)變頻器一般采用大功率中壓(ya)晶(jing)閘管(guan)，輸出(chu)(chu)電(dian)壓(ya)可至12KV，大功率可至100MW，輸出(chu)(chu)的是電(dian)壓(ya)方波，可采用矢量(liang)控(kong)制。主要用于大型(xing)的風機和電(dian)力(li)泵設備(bei)。主要的生產(chan)廠家(jia)有德國(guo)(guo)SIEMENS和法國(guo)(guo)的ALSTOM，目前(qian)國(guo)(guo)內沒有類(lei)似的生產(chan)廠家(jia)。
分(fen)析與維修:首先檢查(cha)逆變模塊(kuai)沒有(you)發現(xian)(xian)問(wen)題。其(qi)次檢查(cha)驅(qu)動(dong)電路(lu)也沒有(you)異常(chang)(chang)現(xian)(xian)象(xiang)，估計問(wen)題不在這(zhe)一塊(kuai)，可能出在過流信(xin)號處理這(zhe)一部(bu)位(wei)，將其(qi)電路(lu)傳感器拆掉后上(shang)電，顯示一切正(zheng)常(chang)(chang)，故認為(wei)傳感器已壞(huai)，找一新品(pin)換上(shang)后帶負載實(shi)驗一切正(zheng)常(chang)(chang)。
3過壓過電壓報(bao)警一(yi)般是(shi)出現在停機的(de)時候(hou)，其(qi)主要原因是(shi)減速時間太短或制(zhi)動電阻及制(zhi)動單元(yuan)有問題。
