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復方法(fa)

西(xi)門(men)(men)子G150變(bian)頻(pin)(pin)器(qi)開機(ji)后(hou)無任何(he)反應(ying)維修(xiu)，對于我們恒稅(shui)維修(xiu)公司來說(shuo)已經是“家常便飯"了，每(mei)個月(yue)都有(you)客戶打電話來說(shuo)西(xi)門(men)(men)子G150壞了，開機(ji)沒反應(ying)，變(bian)頻(pin)(pin)器(qi)面板(ban)(ban)電源指示(shi)燈不亮(liang)了，面板(ban)(ban)顯示(shi)器(qi)也不顯示(shi)，開機(ji)顯示(shi)器(qi)無任何(he)字符，同時按操作面板(ban)(ban)上的所有(you)鍵也都沒有(you)反應(ying)，散熱風扇也不轉(zhuan)了。如果客戶距離比較遠的話，就(jiu)讓客戶把變(bian)頻(pin)(pin)器(qi)寄過來維修(xiu)

西(xi)門子G150變(bian)頻(pin)器開機(ji)后無任何反應維修時，恒稅(shui)電(dian)氣(qi)是這(zhe)樣做的：

首先(xian)(xian)我們(men)先(xian)(xian)把(ba)變(bian)頻(pin)器(qi)檢測一遍(bian)后再分析，通過我們(men)以(yi)西門子(zi)G150變(bian)頻(pin)器(qi)的(de)整機的(de)結(jie)構、各電路的(de)作用(yong)以(yi)及各電路之間的(de)連接與工作順序來分析。

首(shou)先(xian)檢測西(xi)門子G150變(bian)(bian)頻器交流(liu)(liu)(liu)(liu)如(ru)端(duan)接(jie)觸點有(you)(you)無交流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)輸(shu)(shu)入，如(ru)果(guo)如(ru)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)正常(chang)，我們可以拆(chai)機檢查測量(liang)主電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中整流(liu)(liu)(liu)(liu)濾(lv)(lv)(lv)波之后(hou)濾(lv)(lv)(lv)波電(dian)(dian)(dian)(dian)(dian)(dian)容器兩(liang)端(duan)的直(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是否(fou)(fou)正常(chang)。如(ru)果(guo)測量(liang)時(shi)(shi)直(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為0，檢查抗干擾(rao)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中交流(liu)(liu)(liu)(liu)熔絲(si)與熱(re)敏電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)等是否(fou)(fou)開(kai)路(lu)(lu)。同時(shi)(shi)檢查整流(liu)(liu)(liu)(liu)濾(lv)(lv)(lv)波元件，如(ru)果(guo)濾(lv)(lv)(lv)波電(dian)(dian)(dian)(dian)(dian)(dian)容器兩(liang)端(duan)直(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)正常(chang)，再(zai)測二(er)次(ci)開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)源脈(mo)(mo)沖變(bian)(bian)頻器次(ci)級各(ge)整流(liu)(liu)(liu)(liu)濾(lv)(lv)(lv)波電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是否(fou)(fou)都(dou)符(fu)合標準(zhun)。如(ru)果(guo)各(ge)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)都(dou)為0，說明二(er)次(ci)開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)源沒(mei)有(you)(you)振(zhen)蕩(dang)。重(zhong)點檢測振(zhen)蕩(dang)開(kai)關(guan)管與正反(fan)饋電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)以及開(kai)關(guan)振(zhen)蕩(dang)管源極對地保(bao)險電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是否(fou)(fou)開(kai)路(lu)(lu)。如(ru)果(guo)我們測試開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)源脈(mo)(mo)沖變(bian)(bian)壓(ya)(ya)器應該(gai)顯示字符(fu)。當我們操(cao)作(zuo)RUN啟動鍵(jian)時(shi)(shi)，應測U、V、W三(san)端(duan)有(you)(you)無變(bian)(bian)頻交流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)輸(shu)(shu)出且各(ge)輸(shu)(shu)是否(fou)(fou)正常(chang)，三(san)相電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)是否(fou)(fou)平衡。

西門子G150變頻器(qi)開機(ji)后(hou)無任何反(fan)應維修(xiu)，根據上(shang)述分析(xi)來看，客戶(hu)的(de)變頻器(qi)主(zhu)要(yao)故(gu)障主(zhu)要(yao)出現在主(zhu)電(dian)(dian)(dian)路中的(de)抗干擾與整流濾波以(yi)及二次開關電(dian)(dian)(dian)源(yuan)等電(dian)(dian)(dian)路問(wen)題。按(an)電(dian)(dian)(dian)路的(de)工作順(shun)序去(qu)檢查，可以(yi)使電(dian)(dian)(dian)源(yuan)指示燈亮(liang)，面(mian)板(ban)顯示器(qi)顯示字符，然后(hou)再(zai)分析(xi)檢查。**檢修(xiu)啟動后(hou)，U、V、W三(san)端(duan)輸出**頻率(lv)的(de)三(san)相(xiang)(xiang)相(xiang)(xiang)互平衡(heng)的(de)交(jiao)流電(dian)(dian)(dian)壓送(song)電(dian)(dian)(dian)動機(ji)。

無論任何(he)電氣設備在(zai)出現(xian)故障時，都是由整機(ji)某一(yi)單元(yuan)(yuan)電路(lu)或某一(yi)元(yuan)(yuan)器件損(sun)壞而造成的(de)(de)。我(wo)們要(yao)將(jiang)整機(ji)每個單元(yuan)(yuan)小(xiao)路(lu)工作(zuo)與結構(gou)特點(dian)詳(xiang)細搞清晰，明白每個單元(yuan)(yuan)電路(lu)中每個重要(yao)容易損(sun)壞的(de)(de)元(yuan)(yuan)件在(zai)本(ben)電路(lu)所處的(de)(de)位置，起什么作(zuo)用，才能分析出西門子(zi)G150變頻(pin)器開要(yao)后無任何(he)反應，是哪(na)一(yi)部(bu)分出現(xian)了問題

西門子G150變頻器開不了機不啟動解決修復方法；快速修復故障：炸可控硅，無顯示，模塊炸，開不了機維修，變頻器無輸出，無電壓，變頻器冒煙，變頻器異響，變頻器報警，通訊不上，帶不動負載，電機不轉，電機抖動,面板顯示’E’面板無顯示，驅動板燒，驅動電路壞，電壓輸出不平衡，運行幾分鐘報過流.缺相、過流、過壓、欠壓、過熱、過載、接地,報錯。
