style="font-size:14px;">變頻器的主電路大體上可分為兩類：電壓型是將電壓源的直流變換為交流的變頻器，直流回路的濾波是電容；電流型是將電流源的直流變換為交流的變頻器，其直流回路濾波是電感。電動機使用工頻電源驅動時，電壓下降則電流增加；對于變頻器驅動，如果頻率下降時電壓也下降，那么電流是否增加？頻率下降（低速）時，如果輸出相同的功率,則電流增加，但在轉矩一定的條件下,電流幾乎不變。采用變頻器運轉，隨著電機的加速相應提高頻率和電壓，起動電流被限制在150%額定電流以下(根據(jù)機種不同，為125%~200%)。<strong>【云南永樂科技有限公司主要銷售維修變頻器、ABB變頻器、英威騰變頻器、東力變頻器、施耐德變頻器、西門子變頻器等等，如有需求，歡迎大家來電咨詢！】</strong></span>昆明進口變頻器維修公司公司擁有***的產(chǎn)品，歡迎您前來選購。</p><div

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、變頻器的負載類型；如葉片泵或容積泵等，特別注意負載的性能曲線，性能曲線決定了應用時的方式方法。</span> </p> <p> <span style="font-size:14px;">3、變頻器與負載的匹配問題；</span> </p> <p> <span style="font-size:14px;">1)電壓匹配；變頻器的額定電壓與負載的額定電壓相符。</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</span><span style="font-size:14px;">流相符。對于特殊的負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> <p> <span style="font-size:14px;">3)轉矩匹配；這種情況在恒轉矩負載或有減速裝置時有可能發(fā)生。<strong>【云南永樂科技有限公司主要銷售維修變頻器、ABB變頻器、英威騰變頻器、東力變頻器、施耐德變頻器、西門子變頻器等等，如有需求，歡迎大家來電咨詢！】</strong></span> </p><p> <span style="font-size:14px;">在變頻器實際應用中，由于國內(nèi)客戶除少數(shù)有專屬機房外，大多為了降低成本，將變頻器直接安裝于工業(yè)現(xiàn)場。工作現(xiàn)場一般有灰塵大、溫度高、濕度大的問題，還有如鋁行業(yè)中有金屬粉塵、腐蝕性氣體等等。因此必須根據(jù)現(xiàn)場情況做出相應的對策：</span> </p> <p> <span style="font-size:14px;">1、變頻器應該安裝在控制柜內(nèi)部。</span> </p> <p> <span style="font-size:14px;">2、變頻器較好安裝在控制柜內(nèi)的中部；變頻器要垂直安</span><span style="font-size:14px;">裝，正上方和正下方要避免安裝可能阻擋排風、進風的大元件。</span> </p> <p> <span style="font-size:14px;">3、變頻器上、下部邊緣距離控制柜頂部、底部、或者隔板、或者必須安裝的大元件等的蕞小間距，應該大于300mm。</span> </p> <p> <span style="font-size:14px;">4、如果特殊用戶在使用中需要取掉鍵盤，則變頻器面板的鍵盤孔，一定要用膠帶嚴格密封或者采用假面板替換，防止粉塵大量進入變頻器內(nèi)部。</span> </p> <p> <span

style="font-size:14px;">在靜態(tài)測試結果正常以后，才可進行動態(tài)測試，即上電試機。在上電前后必須注意以下幾點：</span> </p> <p> <span style="font-size:14px;">1、上電之前，須確認輸入電壓是否有誤，將380V電源接入220V級變頻器之中會出現(xiàn)炸機（炸電容、壓敏電阻、模塊等）；</span> </p> <p> <span style="font-size:14px;">2、檢查變頻器各接插口是否已正確連接，連接是否有松動，連接異常有時可能會導致變頻器出現(xiàn)故障，嚴重時會出炸機等情況；</span> </p> <p> <span style="font-size:14px;">3、上電后檢測故障顯示內(nèi)容，并初步斷定故障及原因；</span> </p> <p> <span style="font-size:14px;">4、如未顯示故障，首先檢查參數(shù)是否有異常，并將參數(shù)復歸后，在空載（不接電機）情況下啟動變頻器，并測試U、V、W三相輸出電壓值。如出現(xiàn)缺相、三相不平衡等情況，則模塊或驅動板等有故障；</span> </p> <p> <span style="font-size:14px;">5、在輸出電壓正常（無缺相、三相平衡）的情況下，負載測試，盡量是滿負載測試。</span> </p> <p> <span
