style="font-size:14px;">1、整流模塊損壞：通常是由于電網(wǎng)電壓或內(nèi)部短路引起。在排除內(nèi)部短路情況下，更換整流橋。在現(xiàn)場處理故障時(shí)，應(yīng)重點(diǎn)檢查用戶電網(wǎng)情況，如電網(wǎng)電壓，有無電焊機(jī)等對電網(wǎng)有污染的設(shè)備等。</span> </p> <p> <span style="font-size:14px;">2、逆變模塊損壞：通常是由于電機(jī)或電纜損壞及驅(qū)動(dòng)電路故障引起。在修復(fù)驅(qū)動(dòng)電路之后，測驅(qū)動(dòng)波形良好狀態(tài)下，更換模塊。在現(xiàn)場服務(wù)中更換驅(qū)動(dòng)板之后，須注意檢查馬達(dá)及連接電纜。在確定無任何故障下，才能運(yùn)行變頻器。</span> </p> <p> <span style="font-size:14px;">3、上電無顯示：通常是由于開關(guān)電源損壞或軟充電電路損壞使直流電路無直流電引起，如啟動(dòng)電阻損壞，操作面板損壞同樣會(huì)產(chǎn)生這種狀況。</span> </p> <p> <span style="font-size:14px;">4、顯示過電壓或欠電壓：通常由于輸入缺相，電路老化及電路板受潮引起。解決方法是找出其電壓檢測電路及檢測點(diǎn)，更換損壞的器件。</span> </p> <p> <span style="font-size:14px;">5、顯示過電流或接地短路：通常是由于電流檢測電路損壞。如霍爾元件、運(yùn)放電路等。</span> </p> <p> <span style="font-size:14px;">6、電源與驅(qū)動(dòng)板啟動(dòng)顯示過電流：通常是由于驅(qū)動(dòng)電路或逆變模塊損壞引起。</span> </p> <p> <span style="font-size:14px;">7、空載輸出電壓正常，帶載后顯示過載或過電流：通常是由于參數(shù)設(shè)置不當(dāng)或驅(qū)動(dòng)電路老化，模塊損壞引起。</span> </p> <p> <span style="font-size:14px;">（云南永樂科技變頻器銷售、維修）</span> 云南Goodrive200A變頻器訂購</p><p
