環(huán)境溫度運行地點的溫度通常規(guī)定為－10～＋40℃。如將變頻器裝在控制柜內(nèi)，變頻器本身的蓋子可以打開，則應(yīng)用在＋50℃以下的場合。貯藏溫度可放寬為－20～＋65℃。 (2) 環(huán)境濕度相對濕度在90％以上，以不冷凝結(jié)露為限。 (3) 安裝位置應(yīng)在海拔 1000m 以下，無腐蝕性氣體，無直射陽光，灰塵不大之處。安裝變頻器應(yīng)注意些什么？比較重要的是變頻器的通風(fēng)須良好。為此，通常要求如下： (1) 變頻器與周圍物體之間的距離應(yīng)小于120mm。 (2) 當兩臺變頻器裝在一個控制柜內(nèi)時，一般應(yīng)并排安裝；如須上下直排安裝時，應(yīng)在兩臺變頻器之間用隔板擋開，避免下面變頻器出來的熱風(fēng)進入到上面的變頻器中去。廈門友億佳自動化設(shè)備有限公司是一家專業(yè)維修變頻器的公司，維修品牌例如下：三菱變頻器維修，安川變頻器維修，松下變頻器維修，西門子變頻器維修，ABB變頻器維修，施耐德變頻器維修，倫茨變頻器維修，博世力士樂變頻器維修，AB變頻器維修，富士變頻器維修，艾默生變頻器維修，東芝變頻器維修，東元變頻器維修，臺達變頻器維修，藍海華騰變頻器維修，日立變頻器維修，森蘭變頻器維修.中達變頻器維修，力士樂變頻器維修等等各品牌。廈門阿爾法變頻器檢修哪里有專業(yè)的變頻器維修？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廈門礦山變頻器修理,變頻器" src="https://tyunfile.71360.com/UploadFile/youyijia/637236007615576172/8239702.jpg"></div><p style="text-indent:25px">通過變頻器的顯示來判斷故障點的所在：(1)過電流故障，這可能是變頻器里面比較常見的故障了。我們首先要排除由于參數(shù)問題而導(dǎo)致的故障。例如電流限制，加速時間過短都有可能導(dǎo)致過電流的產(chǎn)生。然后須判斷是否電流檢測電路出問題了。 (2)過電壓故障，我們首先要排除由于參數(shù)問題而導(dǎo)致的故障。例如減速時間過短，以及因為再生負載而導(dǎo)致的過壓等，然后我們可以看一下輸入側(cè)電壓是否有問題，之后我們可以看一下電壓檢測電路是否出現(xiàn)了故障，通常的電壓檢測電路的電壓采樣點，都是中間直流回路的電壓。 (3)欠電壓，先可以看一下輸入側(cè)電壓是否有問題，然后看一下電壓檢測電路，故障判斷和過壓相同。 (4)快速熔斷器故障，在現(xiàn)行推出的變頻器大多推出了快熔故障檢測功能。特別是大功率變頻器。主要是對快熔前面后面的電壓進行采樣檢測，當快熔損壞以后必然會出現(xiàn)快熔一端電壓沒有，此時隔離光耦動作，出現(xiàn)FU報警。更換快熔就因該能解決問題。特別應(yīng)該注意的是在更換快熔前須判斷主回路是否有問題。 </p><p> 變頻器功率修改有什么好處？許多牌子的變頻器電源板、驅(qū)動板、主板都可以通用，只要型號、體積、硬件一樣，能夠通過修改廠家參數(shù)得到想要的功率以及電壓值，不必再花錢去購買相同功率的配件，自然節(jié)約了維修成本，何樂而不為呢！1、安川變頻器G5-G7功率修改：進入菜單將A01=4后再返回進入02-04里面就是功率數(shù)據(jù)，改完后恢復(fù)出廠電壓也跟著變化了。2、三肯變頻器IHF-IPF-SHF系列：進入CD900號參數(shù)后輸入365確定（改2次）然后找到CD202進去輸入365就能看見功率及電壓參數(shù)了，4-5.5表示400V-5.5KW，先修改電壓然后確定才能修改功率，完成后按確定鍵然后退出。3、施耐德變頻器功率修改：施耐德變頻器換過主板后上電會報警CFF,這時連續(xù)按下ENT鍵3次就恢復(fù)出廠，功率電壓自動匹配。

變頻器使用及故障維修案例一：干擾問題。⑴良好的接地。電機等強電控制系統(tǒng)的接地線須通過接匯流排可靠接地。控制系統(tǒng)比較好**接地，接地電阻小于１Ω。傳感器、Ｉ／Ｏ接口屏蔽層與控制系統(tǒng)的控制地相連。⑵給儀表等輸入電源加裝EMI濾波器、共模電感、高頻磁環(huán)等。⑶給變頻器輸入加裝EMI濾波器，可以有效扼制變頻器對電網(wǎng)的傳導(dǎo)干擾，加裝輸入交流和直流電抗器，可以提高功率因數(shù)，減少諧波污染，綜合效果好。某些電機與變頻器之間距離超過100m的場合，需要在變頻器側(cè)添加交流輸出電抗器，解決因為輸出導(dǎo)線對地分布參數(shù)造成的漏電流保護的減少對外部的輻射干擾。

變頻器日常檢查：每兩周進行一次，檢查記錄運行中的變頻器輸出三相電壓，并注意比較他們之間的平衡度；檢查記錄變頻器的三相輸出電流，并注意比較他們之間的平衡度；檢查記錄環(huán)境溫度，散熱器溫度；察看變頻器有無異常振動，聲響，風(fēng)扇是否運轉(zhuǎn)正常。變頻器保養(yǎng)：每臺變頻器每季度要清灰保養(yǎng)1次。保養(yǎng)要清理變頻器內(nèi)部和風(fēng)路內(nèi)的積灰，臟物，將變頻器表面擦拭干凈；變頻器的表面要保持清潔光亮；在保養(yǎng)的同時要仔細檢查變頻器，察看變頻器內(nèi)有無發(fā)熱變色部位，水泥電阻有無開裂現(xiàn)象，電解電容有無膨脹漏液防爆孔突出等現(xiàn)象，PCB板有否異常，有沒有發(fā)熱燒黃部位。保養(yǎng)結(jié)束后，要恢復(fù)變頻器的參數(shù)和接線，送電，帶電機工作在3Hz的低頻約1分鐘，以確保變頻器工作正常。四、變頻器大修：變頻器大修項目：變頻器具體大修項目主要按照變頻器使用年限以及日常檢查的結(jié)果決定。
