</p> <p> <span style="font-size:14px;">國</span><span style="font-size:14px;">產變頻器由曾經的不調速到如今的調速，在節(jié)能方面已經有了很大的進步。變頻器的電機調速在所有用電量中占據(jù)非常大的份額。以往是通過減少流量和操控風能來達到節(jié)能的效果，但其效果遠遠不如變頻調速來的直接有效，而且經過這樣一個改變，所節(jié)省的成本也大幅度提高。</span> </p> <p> <span style="font-size:14px;">2.風電結合</span> </p> <p> <span style="font-size:14px;">國產變頻器以往都是采用純電的形式，這樣能夠保證提供給機器的電動力是平穩(wěn)且易控制的。但是大家都知道風動力是十分不好控制的一種能量來源，而變頻器對電動力的穩(wěn)定要求性很高，因此就采用風電結合的方式，保障電力的穩(wěn)定。這也是一種新型的環(huán)保動力，在節(jié)能方面也有很大的效果。</span> </p> <p> <span style="font-size:14px;">3.電流的轉變</span> </p> <p> <span style="font-size:14px;">以往運用比較多的是交流變直流的方式，但是直流電機存在很多維修方面的問題，因此會導致諸多故障，昆明建筑機械**變頻器銷售，昆明建筑機械**變頻器銷售。如今隨著可關斷器材的運用成熟，用的較多的就是交直交的方式，昆明建筑機械**變頻器銷售，這樣減少了大部分的故障問題，也達到了節(jié)能的效果。</span>

style="font-size:14px;">變頻器是應用變頻技術，通過改變電機工作電源頻率方式來控制交流電動機的電力控制設備。變頻器主要由整流(交流變直流)、濾波、逆變(直流變交流)、制動單元、驅動單元、檢測單元微處理單元等組成。變頻器靠內部IGBT的開斷來調整輸出電源的電壓和頻率，根據(jù)電機的實際需要來提供其所需要的電源電壓，進而達到節(jié)能、調速的目的，另外，變頻器還有很多的保護功能，如過流、過壓、過載保護等等。隨著工業(yè)自動化程度的不斷提高，變頻器也得到了非常普遍的應用。</span>

style="font-size:14px;">交流一交流變頻器是直接將工頻電源轉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；電網功率因素低：一般情況下，輸出蕞好頻率為電網頻率的1/3一1/2.所以交流一交流變頻器在異步電動機變頻調速方面主要用于低速大功率傳動，特別轉矩要求叫高的場合，如大型的軋鋼機，電機車，低速水泥回轉窯等。這種變頻器是目前中小型異步電動機變頻調速電源的主要形式。這種變頻器從其性質上看，又可分為電壓源變頻器和電流源變頻器。</span></p><p>

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;">電流源變頻器供電時，電動機的啟動轉矩很小，能穩(wěn)定運行的范圍很窄，在大部分的轉速范圍內是電機的運行不穩(wěn)定區(qū)，電機的特性差。因此，在異步電機的變頻調速中很少用這種變頻器，但是，由于其具有容易實現(xiàn)回饋制動，能四象限運行，輸出電壓波形對異步電機接近正弦波，諧波分量小，噪音低，動態(tài)響應快等優(yōu)點，在一些啟動轉矩小，需要經常制動和正、反轉且調速范圍要求較小的機械設備中，應用這種變頻器能夠起到很好的調速的效果。</span><span style="font-size:14px;">電壓源變頻器供電時，電機的特性較好，電動機的啟動轉矩較大，調速范圍較大，平滑性較高，低速時靜差率較高，是目前交流調速中應用蕞普遍的變頻器。這種變頻器，按其控制方式又可分為恒研f比控制和蕞大轉矩保持恒定控制。</span>昆明建筑機械**變頻器銷售</p><p
