描述
當(dāng)一臺(tái)變頻器大電容后的快熔開(kāi)路,或者是IGBT逆變模塊損壞的情況下,驅(qū)動(dòng)電路基本都不可能完好無(wú)損,切不可換上好的快熔或者IGBT逆變模塊,這樣很容易造成剛換上的好的器件再次損壞。這個(gè)時(shí)候應(yīng)該著重檢查下驅(qū)動(dòng)電路上是否有打火的印記,這里可以先將IGBT逆變模塊的驅(qū)動(dòng)腳連線(xiàn)拔掉,用萬(wàn)用表電阻擋測(cè)量六路驅(qū)動(dòng)電路是否阻值都相同(但是極個(gè)別的變頻器驅(qū)動(dòng)電路不是六路阻值都相同的:如三菱、富士等變頻器),如果六路阻值都基本相同還不能完全證明驅(qū)動(dòng)電路是完好的,接著需要使用電子示波器測(cè)量六路驅(qū)動(dòng)電路上電壓是否相同控制工程網(wǎng)版權(quán)所有,當(dāng)給定一個(gè)啟動(dòng)信號(hào)時(shí)六路驅(qū)動(dòng)電路的波形是否一致;如果手里沒(méi)有電子示波器的話(huà),也可以嘗試使用數(shù)字式電子萬(wàn)用表來(lái)測(cè)量驅(qū)動(dòng)電路六路的直流電壓。
