西門子變頻器MM430面板顯示橫杠修理,我(wo)公(gong)司(si)是專業從事(shi)西門子數(shu)控(kong)系統,工業控(kong)制化(hua)系統維修領域內的設(she)備(bei)為主,涉(she)及行業之廣(guang)泛,如:機械制造(zao),磨具加工,液壓(ya),光(guang)伏能源、半導體、紡(fang)織、線纜電器(qi)制造(zao),能源裝(zhuang)備(bei),塑(su)料、醫療、環保、冶金、造(zao)紙、汽車(che)電子、鋼鐵(tie)、化(hua)工、鍋(guo)爐控(kong)制、煉油(you)、石化(hua)、光(guang)纖、橡(xiang)膠、能源發電、裝(zhuang)飾材料等行業。
西門子變頻器MM430面板顯示橫杠修理故障檢(jian)測(ce):該方法主要針對變(bian)(bian)頻(pin)器(qi)(qi)三個方面(mian):首先是(shi)(shi)判(pan)斷直流母線充電(dian)(dian)繼電(dian)(dian)器(qi)(qi)/接(jie)觸(chu)器(qi)(qi)吸合是(shi)(shi)否正常(chang),這對排除變(bian)(bian)頻(pin)器(qi)(qi)運(yun)行(xing)過程(cheng)中報欠(qian)壓(ya)故障非常(chang)重要。再者(zhe)細聽(ting)開(kai)關(guan)電(dian)(dian)源所用變(bian)(bian)壓(ya)器(qi)(qi)有無異響,這對于初步(bu)判(pan)定(ding)開(kai)關(guan)電(dian)(dian)源部分是(shi)(shi)否存在過載現象,同樣十(shi)分有效。后(hou)就(jiu)是(shi)(shi)針對變(bian)(bian)頻(pin)器(qi)(qi)散熱風扇運(yun)行(xing)情況的(de)監聽(ting)。
在變頻(pin)器(qi)出(chu)(chu)現(xian)故障斷電(dian)(dian)后,迅速(su)拆機并做好防護(hu)工(gong)作用手(shou)指(zhi)肚快速(su)觸摸(mo)變頻(pin)器(qi)內部線路(lu)板上(shang)的相(xiang)關(guan)電(dian)(dian)子元器(qi)件(jian)、IC集成塊等。一旦(dan)發(fa)現(xian)某些元件(jian)同比溫(wen)升明顯,則故障必在它身上(shang)或(huo)者其(qi)周圍線路(lu)當中(zhong)!圖(tu)二展示的為某品牌(pai)35KW變頻(pin)器(qi),因直流(liu)母線電(dian)(dian)壓監測電(dian)(dian)阻(zu)阻(zu)值變質而引發(fa)直流(liu)母線過電(dian)(dian)壓保護(hu),從圖(tu)中(zhong)可感覺(jue)到(dao)事發(fa)時(shi)電(dian)(dian)阻(zu)所(suo)散發(fa)出(chu)(chu)的熱量(liang)有多(duo)高!
當變頻(pin)器工(gong)作(zuo)中(zhong)如果出現(xian)工(gong)作(zuo)時(shi)好時(shi)壞現(xian)象,有可能(neng)是(shi)內部線路當中(zhong)有某些元(yuan)件(jian)發生開焊(han)故障所致。對(dui)于一(yi)些管腳排列細密且眾多的(de)(de)(de)貼(tie)(tie)片(pian)IC而言,單(dan)純憑借(jie)肉眼觀察發現(xian)有無(wu)問題(ti)實(shi)屬不(bu)易。此(ci)刻我們不(bu)妨借(jie)助(zhu)絕緣的(de)(de)(de)塑料棒/木棒(嚴禁使用導電的(de)(de)(de)金屬物(wu)品),在通電狀態下適當用力按壓(ya)懷(huai)疑的(de)(de)(de)元(yuan)件(jian)。該方法對(dui)于排除小型貼(tie)(tie)片(pian)元(yuan)件(jian)尤其是(shi)貼(tie)(tie)片(pian)式IC十分(fen)有效(xiao),不(bu)過在操作(zuo)時(shi)一(yi)定要做好防觸電、防短路工(gong)作(zuo)。
