西門子G150變頻器開不了機不啟動解決，西門子交流變頻調速器修(xiu)復(fu)方(fang)法

西門子G150變頻器開機后無任(ren)何反(fan)應(ying)維(wei)(wei)修，對(dui)于我(wo)們恒稅維(wei)(wei)修公(gong)司來說已(yi)經是(shi)“家常便(bian)飯"了，每個月都有(you)客戶(hu)打電(dian)話來說西門子G150壞(huai)了，開機沒(mei)反(fan)應(ying)，變頻器面(mian)板(ban)電(dian)源指(zhi)示(shi)燈不亮了，面(mian)板(ban)顯(xian)示(shi)器也不顯(xian)示(shi)，開機顯(xian)示(shi)器無任(ren)何字(zi)符，同(tong)時按(an)操(cao)作(zuo)面(mian)板(ban)上的(de)所(suo)有(you)鍵也都沒(mei)有(you)反(fan)應(ying)，散(san)熱風扇也不轉了。如果(guo)客戶(hu)距離比較遠的(de)話，就讓客戶(hu)把變頻器寄過來維(wei)(wei)修

西(xi)門子G150變(bian)頻器開機后(hou)無任何反應維修時，恒稅電氣是這(zhe)樣(yang)做(zuo)的：

首(shou)先我們先把變(bian)頻(pin)器檢測一遍后再分(fen)析(xi)，通過我們以西門子G150變(bian)頻(pin)器的整機的結構、各電(dian)路的作用(yong)以及(ji)各電(dian)路之(zhi)間的連接與工作順序來分(fen)析(xi)。

首先檢(jian)(jian)測(ce)西門子G150變(bian)頻器(qi)(qi)交流(liu)(liu)(liu)如端(duan)(duan)(duan)(duan)接觸點有無交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)輸(shu)入，如果(guo)如端(duan)(duan)(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)正(zheng)常，我們可以拆(chai)機檢(jian)(jian)查測(ce)量主電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中整流(liu)(liu)(liu)濾(lv)(lv)波之后濾(lv)(lv)波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)兩端(duan)(duan)(duan)(duan)的直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)否(fou)正(zheng)常。如果(guo)測(ce)量時直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)(wei)0，檢(jian)(jian)查抗干擾(rao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中交流(liu)(liu)(liu)熔絲與熱(re)敏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)等是(shi)否(fou)開(kai)(kai)路(lu)。同(tong)時檢(jian)(jian)查整流(liu)(liu)(liu)濾(lv)(lv)波元件，如果(guo)濾(lv)(lv)波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)兩端(duan)(duan)(duan)(duan)直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)正(zheng)常，再測(ce)二次開(kai)(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)脈沖變(bian)頻器(qi)(qi)次級(ji)各整流(liu)(liu)(liu)濾(lv)(lv)波電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)否(fou)都(dou)符合標準。如果(guo)各電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)都(dou)為(wei)(wei)0，說明二次開(kai)(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)沒有振(zhen)蕩。重點檢(jian)(jian)測(ce)振(zhen)蕩開(kai)(kai)關(guan)管與正(zheng)反(fan)饋電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)以及開(kai)(kai)關(guan)振(zhen)蕩管源(yuan)(yuan)極對地保險電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)否(fou)開(kai)(kai)路(lu)。如果(guo)我們測(ce)試開(kai)(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)脈沖變(bian)壓(ya)(ya)器(qi)(qi)應該顯示字符。當我們操(cao)作(zuo)RUN啟動鍵時，應測(ce)U、V、W三端(duan)(duan)(duan)(duan)有無變(bian)頻交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)輸(shu)出且各輸(shu)是(shi)否(fou)正(zheng)常，三相(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是(shi)否(fou)平衡。

西門子G150變頻器開機后無任何(he)反(fan)應維修，根據上(shang)述分析(xi)來(lai)看，客(ke)戶(hu)的(de)(de)(de)變頻器主要故障主要出現在主電(dian)(dian)路(lu)中的(de)(de)(de)抗(kang)干(gan)擾(rao)與整(zheng)流(liu)濾波以(yi)及二次(ci)開關電(dian)(dian)源(yuan)等電(dian)(dian)路(lu)問題。按(an)電(dian)(dian)路(lu)的(de)(de)(de)工(gong)作順序去檢(jian)查(cha)(cha)，可(ke)以(yi)使電(dian)(dian)源(yuan)指示(shi)燈亮，面板顯示(shi)器顯示(shi)字(zi)符，然后再分析(xi)檢(jian)查(cha)(cha)。**檢(jian)修啟(qi)動后，U、V、W三端輸(shu)出**頻率(lv)的(de)(de)(de)三相相互平衡的(de)(de)(de)交流(liu)電(dian)(dian)壓送電(dian)(dian)動機。

無論任何(he)電氣設備在出(chu)現故障(zhang)時(shi)，都是(shi)由整機某一單(dan)元電路(lu)或(huo)某一元器(qi)(qi)件(jian)損壞而造成(cheng)的。我們要將整機每(mei)(mei)個單(dan)元小路(lu)工作(zuo)與結(jie)構特點(dian)詳(xiang)細搞清晰，明(ming)白每(mei)(mei)個單(dan)元電路(lu)中每(mei)(mei)個重(zhong)要容易(yi)損壞的元件(jian)在本(ben)電路(lu)所處(chu)的位置，起(qi)什么作(zuo)用，才能分析出(chu)西門(men)子G150變頻器(qi)(qi)開(kai)要后無任何(he)反(fan)應，是(shi)哪一部(bu)分出(chu)現了問題
