 　故障(zhang)原(yuan)因：外部連接(jie)的電機(ji)電纜故障(zhang)或變頻器自身硬件故障(zhang)。 
　　處理(li)方法：脫開變(bian)(bian)頻(pin)器(qi)的輸(shu)出(chu)(chu)線(xian)，用(yong)兆歐表測量三相(xiang)對地(di)絕(jue)緣情況和(he)三相(xiang)電(dian)(dian)(dian)組，如(ru)果(guo)電(dian)(dian)(dian)機(ji)或電(dian)(dian)(dian)纜有(you)問(wen)題，更換電(dian)(dian)(dian)機(ji)和(he)電(dian)(dian)(dian)纜；如(ru)果(guo)輸(shu)出(chu)(chu)正常(chang)的話(hua)，就檢查變(bian)(bian)頻(pin)器(qi)的主(zhu)回(hui)路，主(zhu)要檢查IGBT、逆變(bian)(bian)塊和(he)整(zheng)流(liu)(liu)橋(qiao)等。如(ru)何判(pan)斷IGBT、逆變(bian)(bian)塊和(he)整(zheng)流(liu)(liu)橋(qiao)是否正常(chang)呢(ni)，這(zhe)里我把上述完好電(dian)(dian)(dian)器(qi)件用(yong)萬用(yong)表二極管檔進行測試，測試結果(guo)如(ru)：
　　① 對于IGBT，萬用表(biao)黑表(biao)筆(bi)測C，紅表筆測E時(shi)，阻值為0．34MΩ左右，反(fan)之無窮(qiong)大(da)。其(qi)它四種情況均(jun)為均(jun)無窮(qiong)大(da)。
