style="font-size:14px;">因一些公司的生產(chǎn)特性，各電氣mcc室的腐蝕氣體濃度過大，致使很多電氣設備因腐蝕損壞（包括變頻器）。為了解決以上問題可安裝一套空調(diào)系統(tǒng)，用正壓新鮮風來改善環(huán)境條件。為減少腐蝕性氣體對電路板上元器件的腐蝕，還可要求變頻器生產(chǎn)廠家對線路板進行防腐加工，維修后也要噴涂防腐劑，有效地降低了變頻器的故障率，提高了使用效率。在保養(yǎng)的同時要仔細檢查變頻器，定期送電，帶電機工作在2hz的低頻約10分鐘，以確保變頻器工作正常。</span>

style="text-indent:25px"><span style="font-size:14px;"></span><span style="font-size:14px;">交流一交流變頻器是直接將工頻電源轉(zhuǎn)變成所需頻率的交流電源，所以也稱直接變頻。其特點是：一次變流，效率高；能四象限運行：低頻時輸出波形為正弦；電網(wǎng)功率因素低：一般情況下，輸出蕞好頻率為電網(wǎng)頻率的1/3一1/2.所以交流一交流變頻器在異步電動機變頻調(diào)速方面主要用于低速大功率傳動，特別轉(zhuǎn)矩要求叫高的場合，如大型的軋鋼機，電機車，低速水泥回轉(zhuǎn)窯等。這種變頻器是目前中小型異步電動機變頻調(diào)速電源的主要形式。這種變頻器從其性質(zhì)上看，又可分為電壓源變頻器和電流源變頻器。<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><strong></strong></span></p><p> <span style="font-size:14px;">這里列了一些我們選擇變頻器時，我們需要關(guān)注的問題。</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;">電壓匹配；變頻器的額定電</span><span style="font-size:14px;">壓與負載的額定電壓相符。</span> </p> <p> <span style="font-size:14px;">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;"><span

style="font-size:14px;">對于小容量也有無冷卻風扇的機種。有風扇的機種，風的方向是從下向上，所以裝設變頻器的地方，上、下部不要放置妨礙吸、排氣的機械器材。還有，變頻器上方不要放置怕熱的零件等。風扇發(fā)生故障時，由電扇停止檢測或冷卻風扇上的過熱檢測進行保護</span> </p> <p> <span style="font-size:14px;">2、濾波電容器為消耗品，那么怎樣判斷它的壽命？</span> </p> <p> <span style="font-size:14px;">作為濾波電容器使用的電容器，其靜電容量隨著時間的推移而緩緩減少，定期地測量靜電容量，以達到產(chǎn)品額定容量的85%時為基準來判斷壽命。</span> </p> <p> <span

style="font-size:14px;">在變頻器安裝中，通常會設置雷電吸收網(wǎng)絡來防止瞬時雷電侵入和損壞變頻器。然而，在實際工作中，當電力線路架空引入時，單純的變頻器吸收網(wǎng)絡不能滿足要求。在閃電活躍的地區(qū)，這個問題尤為重要。如果電源為架空進線，則應在進線處安裝一個專門用的變頻避雷器(可選)，或根據(jù)規(guī)范要求，在距離變頻器20m處埋設一根鋼管進行特殊接地保護。如果電源通過電纜引入，控制室的防雷系統(tǒng)應做好準備，防止雷電進入并損壞設備。實踐表明，該方法能夠基本有效地解決雷擊問題。</span><span style="font-size:14px;">變頻器正確接地是提高控制系統(tǒng)靈敏度和控制</span><span style="font-size:14px;">噪聲的重要手段。變頻器接地端子E(G)的接地電阻越小越好。接地導體的截面積應不小于2mm2，長度應控制在20m以內(nèi)。變頻器的接地必須與電力設備的接地點分開，不能共用。信號輸入線的屏蔽層應接E(G)，另一端不得接地，否則會引起信號變化波動，使系統(tǒng)振蕩不止一次。變頻器和控制柜應電氣連接。如果安裝困難，可以用銅線跨接。<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><strong></strong></span>昆明供水變頻器故障維修</p></p><br
