style="font-size:14px;">變頻器（Variable-frequencyDrive，縮寫：VFD），也稱為變頻驅(qū)動器或驅(qū)動控制器，可譯作Inverter（和逆變器的英文相同）。變頻器是可調(diào)速驅(qū)動系統(tǒng)的一種，是應(yīng)用變頻驅(qū)動技術(shù)改變交流電動機工作電壓的頻率和幅度，來平滑控制交流電動機速度及轉(zhuǎn)矩，蕞常見的是輸入及輸出都是交流電的交流/交流轉(zhuǎn)換器。在變頻器出現(xiàn)之前，要調(diào)整電動機轉(zhuǎn)速的應(yīng)用需透過直流電動機才能完成，不然就是要透過利用內(nèi)建耦合機的VS電動機，在運轉(zhuǎn)中用耦合機使電動機的實際轉(zhuǎn)速下降，變頻器簡化了上述的工作，縮小了設(shè)備體積，大幅度降低了維修率。不過變頻器的電源線及電動機線上面有高頻切換的訊號，會造成電磁干擾，而變頻器輸入側(cè)的功率因素一般不佳，會產(chǎn)生電源端的諧波。<strong>（云南永樂科技變頻器銷售、維修）</strong></span></p><p> <span style="font-size:14px;">變頻器選型時要確定以下幾點：</span> </p> <p> <span style="font-size:14px;">1、采用變頻的目的；恒壓控制或恒流控制等。</span> </p> <p> <span style="font-size:14px;">2、變頻器的負(fù)載類</span><span

style="font-size:14px;">1)電壓匹配；變頻器的額定電壓與負(fù)載的額定電壓相符。</span> </p> <p> <span style="font-size:14px;">2)電流匹配；普通的離心泵，變頻器的額定電流與電機的額定電流相符。對于特殊的負(fù)載如深水泵等則需要參考電機性能參數(shù)，以蕞大電流確定變頻器電流和過載能力。</span> </p>

style="font-size:14px;">變頻器正確接地是提高控制系統(tǒng)靈敏度、降低噪聲能力的重要手段，變頻器接地端子E(G)接地電阻越小越好，接地導(dǎo)線截面積應(yīng)不小于2mm2，長度應(yīng)控制在20m以內(nèi)。變頻器的接地必須與動力設(shè)備接地點分開，不能共地。信號輸入線的屏蔽層，應(yīng)接至E(G)上，其另一端絕不能接于地端，否則會引起信號變化波動，使系統(tǒng)振蕩不止。變頻器與控制柜之間應(yīng)電氣連通，如果實際安裝有困難，可利用銅芯導(dǎo)線跨接。在變頻器中，一般都設(shè)有雷電吸收網(wǎng)絡(luò)，主要防止瞬間的雷電侵入，使變頻器損壞。但在實際工作中，特別是電源線架空引入的情況下，單靠變頻器的吸收網(wǎng)絡(luò)是不能滿足要求的。<strong>（云南永樂科技變頻器銷售、維修）</strong></span>昆明變頻器維修公司。昆明施耐德變頻器批發(fā)公司</p><p

style="font-size:14px;">故障判斷</span> </p> <p> <span 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，應(yīng)重點檢查用戶電網(wǎng)情況，如電網(wǎng)電壓，有無電焊機等對電網(wǎng)有污染的設(shè)備等。</span> </p> <p> <span style="font-size:14px;">2、逆變模塊損壞：通常是由于電機或電纜損壞及驅(qū)動電路故障引起。在修復(fù)驅(qū)動電路之后，測驅(qū)動波形良好狀態(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，如啟動電阻損壞，操作面板損壞同樣會產(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，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、運放電路等。</span> </p> <p> <span style="font-size:14px;">6、電源與驅(qū)動板啟動顯示過電流：通常是由于驅(qū)動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)動電路老化，模塊損壞引起。</span> </p> <p>
