當天解決好西門子直流調速裝置無勵磁電壓；控制(zhi)器(qi)維修方(fang)法應當以(yi)生產設備(bei)合用(yong)為標準關(guan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)故障(zhang)(zhang)在(zai)第二級(ji)開(kai)關(guan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)設計上電(dian)(dian)(dian)(dian)路(lu)(lu)結構特點(dian)。可(ke)以(yi)分為振蕩和(he)穩壓控制(zhi)電(dian)(dian)(dian)(dian)路(lu)(lu)，推動和(he)逆變輸(shu)出(chu)三(san)個部(bu)分。分故障(zhang)(zhang)范圍和(he)維修。那么(me)開(kai)關(guan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)故障(zhang)(zhang)的(de)檢修難點(dian)和(he)要求有哪些(xie)？處于正常(chang)還是(shi)非正常(chang)的(de)狀(zhuang)態(tai)。將(jiang)原電(dian)(dian)(dian)(dian)路(lu)(lu)中振蕩和(he)穩壓電(dian)(dian)(dian)(dian)路(lu)(lu)電(dian)(dian)(dian)(dian)路(lu)(lu)繪(hui)出(chu)。都與(yu)此(ci)大致(zhi)相近。由此(ci)電(dian)(dian)(dian)(dian)路(lu)(lu)的(de)深入(ru)分析。可(ke)以(yi)找到掌握檢修變頻器(qi)開(kai)關(guan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)路(lu)(lu)的(de)故障(zhang)(zhang)。.

當開關電源電路正常工作時。下面以振蕩芯片上的檢測方法做簡單介紹：
開關電源電路正常工作時，振蕩芯片的各腳電壓系變頻器待機狀態由萬用表的電壓擋，沒得的實際電壓值，開關電源的實際工作供電一般為16-20V左右。  
1、直流電壓檢(jian)測壞。

2、控制卡損壞。

3、U相、W相傳(chuan)感(gan)器損壞(huai)。

首先(xian)，檢(jian)測(ce)(ce)(ce)(ce)第一(yi)種可能性(xing)。測(ce)(ce)(ce)(ce)試輸入電(dian)壓為380V,用通(tong)訊軟(ruan)件讀變頻器(qi)的直(zhi)流電(dian)壓，顯(xian)示為540VDC，正常(chang)！排除直(zhi)流電(dian)壓檢(jian)測(ce)(ce)(ce)(ce)故障原因。如(ru)果以上數據不正常(chang)，就可以判定是直(zhi)流電(dian)壓檢(jian)測(ce)(ce)(ce)(ce)問題。

其次(ci)，檢測控制卡(ka)狀(zhuang)況。更換一塊良(liang)好的(de)控制卡(ka)，上電，還是顯(xian)示“CF3”故障(zhang)報警。說明原來的(de)控制卡(ka)沒問題。如果(guo)顯(xian)示正常，設置參(can)數，變頻器開機運(yun)行(xing)正常，說明是原來的(de)控制卡(ka)壞。需要做(zuo)進一步的(de)板卡(ka)線路檢修。
