故障現(xiàn)象：一臺(tái)配套某系統(tǒng)的臥式加工中心，在加工時(shí)主軸運(yùn)行突然停止，驅(qū)動(dòng)器顯示過(guò)電流報(bào)警。 </p> <p> 分析與處理過(guò)程：經(jīng)查交流主軸驅(qū)動(dòng)器主回路，發(fā)現(xiàn)再生制動(dòng)回路故障、主回路的熔斷器均熔斷，經(jīng)更換熔斷器后機(jī)床恢復(fù)正常。但機(jī)床正常運(yùn)行數(shù)天后，再次出現(xiàn)同樣故障。 </p> <p> 由于故障重復(fù)出現(xiàn)，證明該機(jī)床主軸系統(tǒng)存在問(wèn)題，根據(jù)報(bào)警現(xiàn)象，分析可能存在的主要原因有： </p> <p> ① 主軸驅(qū)動(dòng)器控制板不良。 </p> <p> ② 連續(xù)過(guò)載。 </p> <p> ③ 繞組存在局部短路。 </p> <p> 在以上幾點(diǎn)中，根據(jù)現(xiàn)場(chǎng)實(shí)際加工情況，過(guò)載的原因可以排除?？紤]到換上元器件后，驅(qū)動(dòng)器可以正常工作數(shù)天，故主軸驅(qū)動(dòng)器控制板不良的可能性已較小。因此，故障原因可能性zui大的是繞組存在局部短路。 </p> <p> 維修時(shí)仔細(xì)測(cè)量繞組的各項(xiàng)電阻，發(fā)現(xiàn)U相對(duì)地絕緣電阻較小，證明該相存在局部對(duì)地短路。 </p> <p> 拆開(kāi)檢查發(fā)現(xiàn)，內(nèi)部繞組與引出線的連接處絕緣套已經(jīng)老化；經(jīng)重新連接后，對(duì)地電阻恢復(fù)正常。 </p> <p> 再次更換元器件后，機(jī)床恢復(fù)正常，故障不再出現(xiàn)。 </p> </p><p
