 我(wo)們使用的(de)(de)電源分為交(jiao)流(liu)(liu)電源和直流(liu)(liu)電源，一般的(de)(de)直流(liu)(liu)電源大多是由交(jiao)流(liu)(liu)電源通過變壓(ya)器變壓(ya)，整(zheng)流(liu)(liu)濾波后得到(dao)的(de)(de)。交(jiao)流(liu)(liu)電源在人們使用電源中(zhong)占總使用電源的(de)(de)95％左右(you)。
無論(lun)是(shi)用于(yu)(yu)家(jia)庭(ting)還是(shi)用于(yu)(yu)工廠，單(dan)(dan)相(xiang)交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)和(he)三(san)(san)相(xiang)交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)，其(qi)電(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)頻率(lv)均按各國的(de)(de)規定有一定的(de)(de)標準(zhun)，如(ru)我國大陸(lu)規定，直接用戶單(dan)(dan)相(xiang)交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)為220V，三(san)(san)相(xiang)交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)壓(ya)為380V，頻率(lv)為50Hz，其(qi)它國家(jia)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)頻率(lv)可能于(yu)(yu)我國的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)頻率(lv)不(bu)同，如(ru)有單(dan)(dan)相(xiang)100V/60Hz、三(san)(san)相(xiang)200V/60Hz等等，標準(zhun)的(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)頻率(lv)的(de)(de)交流(liu)(liu)供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源(yuan)叫(jiao)工頻交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)。
通常，把電(dian)(dian)(dian)(dian)壓和(he)(he)頻(pin)(pin)(pin)率(lv)(lv)固定不變(bian)的(de)交流電(dian)(dian)(dian)(dian)變(bian)換為電(dian)(dian)(dian)(dian)壓或頻(pin)(pin)(pin)率(lv)(lv)可變(bian)的(de)交流電(dian)(dian)(dian)(dian)的(de)裝(zhuang)置稱作“變(bian)頻(pin)(pin)(pin)器(qi)”。為了產生(sheng)可變(bian)的(de)電(dian)(dian)(dian)(dian)壓和(he)(he)頻(pin)(pin)(pin)率(lv)(lv)，該(gai)設備首先要把電(dian)(dian)(dian)(dian)源的(de)交流電(dian)(dian)(dian)(dian)變(bian)換為直流電(dian)(dian)(dian)(dian)（DC）。把直流電(dian)(dian)(dian)(dian)（DC）變(bian)換為交流電(dian)(dian)(dian)(dian)（AC）的(de)裝(zhuang)置，其科(ke)學術語為“inverter”(逆變(bian)器(qi))。由于變(bian)頻(pin)(pin)(pin)器(qi)設備中產生(sheng)變(bian)化的(de)電(dian)(dian)(dian)(dian)壓或頻(pin)(pin)(pin)率(lv)(lv)的(de)主要裝(zhuang)置叫(jiao)“inverter”，故該(gai)產品本(ben)身就(jiu)被命名(ming)為“inverter”，即(ji)變(bian)頻(pin)(pin)(pin)器(qi)。

西門子直流調速器6RA7087報警F030維修專家故障現象(xiang)：顯示POFF（欠壓故障）
故障分析(xi)：接入(ru)直流電(dian)(dian)源(yuan)電(dian)(dian)壓(ya)(ya)(ya)，面板上(shang)(shang)沒(mei)有(you)顯示POFF（欠壓(ya)(ya)(ya)故障），只有(you)上(shang)(shang)交流測(ce)(ce)試了，測(ce)(ce)量(liang)(liang)三相(xiang)相(xiang)正常，直流母線電(dian)(dian)壓(ya)(ya)(ya)也正常。這屬于一種假欠壓(ya)(ya)(ya)故障，問題可能出在(zai)板上(shang)(shang)的電(dian)(dian)壓(ya)(ya)(ya)檢測(ce)(ce)保(bao)護電(dian)(dian)路。首先檢查電(dian)(dian)壓(ya)(ya)(ya)取樣(yang)電(dian)(dian)阻，測(ce)(ce)量(liang)(liang)三個電(dian)(dian)阻基(ji)本上(shang)(shang)未變(bian)化，查一個C46電(dian)(dian)容有(you)較嚴重的漏(lou)電(dian)(dian)現象。
故(gu)(gu)障(zhang)原因(yin)：變(bian)頻器采用了(le)電(dian)(dian)阻(zu)分壓(ya)(ya)式，C46并(bing)聯(lian)在R36上，電(dian)(dian)容在這里主要是起緩(huan)沖變(bian)化作用，由于電(dian)(dian)容老化有漏電(dian)(dian)現象，這就相當于給(gei)電(dian)(dian)阻(zu)再(zai)并(bing)聯(lian)了(le)一個(ge)電(dian)(dian)阻(zu)，使取樣電(dian)(dian)壓(ya)(ya)減小，出現了(le)欠(qian)壓(ya)(ya)故(gu)(gu)障(zhang)。
