目前，所有弱電工程都配備了UPS，那么UPS如果出現故障，你會修理嗎？如果廠家不能及時到達現場解決問題，能不能簡單修理一下？本文杭州UPS電源廠家介紹(shao)UPS故(gu)障(zhang)處(chu)理(li)方法簡單UPS,也就是(shi)(shi)說(shuo)，不間斷(duan)電源是(shi)(shi)將電池(chi)(chi)（主(zhu)(zhu)要是(shi)(shi)鉛(qian)酸免維護(hu)電池(chi)(chi)）與主(zhu)(zhu)機(ji)連接(jie)，通過主(zhu)(zhu)機(ji)逆變器等模塊電路將直流(liu)電轉化(hua)為(wei)市政電力的(de)系統(tong)設(she)備(bei)。主(zhu)(zhu)要用(yong)于為(wei)單臺計算(suan)(suan)機(ji)、計算(suan)(suan)機(ji)網絡系統(tong)或電磁閥(fa)、壓力變送器等其他(ta)電力電子(zi)設(she)備(bei)提供(gong)(gong)穩定、不間斷(duan)的(de)電力供(gong)(gong)應(ying)。其功能是(shi)(shi)在外(wai)部(bu)中(zhong)斷(duan)電源的(de)情況下(xia)(xia)，及時向計算(suan)(suan)機(ji)等設(she)備(bei)供(gong)(gong)電，以免影響通信中(zhong)斷(duan)、重要數據丟失(shi)和硬件(jian)損壞。然而，它正在使用(yong)中(zhong)UPS在保(bao)護(hu)其他(ta)對象(xiang)的(de)同時，電源是(shi)(shi)其他(ta)對象(xiang)UPS如果電源本(ben)身經(jing)常出現故(gu)障(zhang)，UPS如果電源出現故(gu)障(zhang)，將無法為(wei)負載(zai)提供(gong)(gong)保(bao)護(hu)功能。在本(ben)文中(zhong)為(wei)大家介紹(shao)一下(xia)(xia)。UPS常見電源故(gu)障(zhang)現象(xiang)分析處(chu)理(li):

常見問題1：

有市電時UPS電源輸出正(zheng)(zheng)(zheng)常(chang)，無市電(dian)(dian)(dian)(dian)(dian)時蜂鳴(ming)器長鳴(ming)，無輸出。故(gu)(gu)障(zhang)分析：從現象判斷為電(dian)(dian)(dian)(dian)(dian)池(chi)和逆變(bian)器故(gu)(gu)障(zhang)，可(ke)(ke)按以(yi)下程(cheng)序檢(jian)查(cha)(cha)(cha)：①檢(jian)查(cha)(cha)(cha)電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓(ya)，看(kan)電(dian)(dian)(dian)(dian)(dian)池(chi)是否(fou)(fou)充電(dian)(dian)(dian)(dian)(dian)不足。如果(guo)(guo)電(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)不足，檢(jian)查(cha)(cha)(cha)電(dian)(dian)(dian)(dian)(dian)池(chi)本身是否(fou)(fou)有(you)(you)故(gu)(gu)障(zhang)或(huo)充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)路(lu)。②如果(guo)(guo)電(dian)(dian)(dian)(dian)(dian)池(chi)工作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)正(zheng)(zheng)(zheng)常(chang)，檢(jian)查(cha)(cha)(cha)逆變(bian)器驅(qu)動電(dian)(dian)(dian)(dian)(dian)路(lu)是否(fou)(fou)正(zheng)(zheng)(zheng)常(chang)，如果(guo)(guo)驅(qu)動電(dian)(dian)(dian)(dian)(dian)路(lu)輸出正(zheng)(zheng)(zheng)常(chang)，則逆變(bian)器損壞。③如果(guo)(guo)逆變(bian)器驅(qu)動電(dian)(dian)(dian)(dian)(dian)路(lu)工作(zuo)(zuo)不正(zheng)(zheng)(zheng)常(chang)，檢(jian)查(cha)(cha)(cha)波形產(chan)生的電(dian)(dian)(dian)(dian)(dian)路(lu)是否(fou)(fou)有(you)(you)PWM如果(guo)(guo)有(you)(you)控制(zhi)信(xin)號輸出，則表(biao)示逆變(bian)器驅(qu)動電(dian)(dian)(dian)(dian)(dian)路(lu)故(gu)(gu)障(zhang)。④若(ruo)波形產(chan)生電(dian)(dian)(dian)(dian)(dian)路(lu)PWM如果(guo)(guo)控制(zhi)信(xin)號輸出，則檢(jian)查(cha)(cha)(cha)其(qi)輸出是否(fou)(fou)因保護電(dian)(dian)(dian)(dian)(dian)路(lu)工作(zuo)(zuo)而被封鎖(suo)，如果(guo)(guo)有(you)(you)，則查(cha)(cha)(cha)明保護原因；⑤如果(guo)(guo)保護電(dian)(dian)(dian)(dian)(dian)路(lu)不工作(zuo)(zuo)，工作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)正(zheng)(zheng)(zheng)常(chang)，波形電(dian)(dian)(dian)(dian)(dian)路(lu)不工作(zuo)(zuo)PWM波形輸出表(biao)明，波形造成電(dian)(dian)(dian)(dian)(dian)路(lu)損壞的排故(gu)(gu)順序也可(ke)(ke)以(yi)逆轉，有(you)(you)時故(gu)(gu)障(zhang)可(ke)(ke)以(yi)更快地發現。

分享常見問題二：

逆(ni)變器(qi)功率級(ji)一(yi)(yi)對(dui)功率放大器(qi)晶體管損壞(huai)。更換(huan)同型號晶體管后，運行一(yi)(yi)段時(shi)(shi)(shi)(shi)間后電(dian)流過大，電(dian)流過大的(de)原因有(you):①過流保護失效。逆(ni)變器(qi)輸(shu)出過電(dian)流時(shi)(shi)(shi)(shi)，過流保護電(dian)路不(bu)(bu)起作(zuo)用；②脈寬調制(zhi)(PWM)組件故障，輸(shu)出兩個(ge)互補波形(xing)不(bu)(bu)對(dui)稱(cheng)(cheng)，一(yi)(yi)個(ge)導(dao)通(tong)時(shi)(shi)(shi)(shi)間長，另(ling)一(yi)(yi)個(ge)導(dao)通(tong)時(shi)(shi)(shi)(shi)間短，使(shi)臂工作(zuo)不(bu)(bu)平衡(heng)，甚至(zhi)臂同時(shi)(shi)(shi)(shi)導(dao)通(tong)，造成兩管損壞(huai)；③功率管的(de)參數相(xiang)差很大。此(ci)時(shi)(shi)(shi)(shi)，即(ji)使(shi)輸(shu)入對(dui)稱(cheng)(cheng)波形(xing)，輸(shu)出也會(hui)不(bu)(bu)對(dui)稱(cheng)(cheng)。波形(xing)通(tong)過輸(shu)出變壓器(qi)引(yin)起偏磁，即(ji)磁通(tong)不(bu)(bu)平衡(heng)，導(dao)致(zhi)變壓器(qi)飽(bao)和，電(dian)流急劇增加，燃燒功率管，一(yi)(yi)個(ge)燃燒，另(ling)一(yi)(yi)個(ge)燃燒。

常見問題三：

電(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)壓低，但(dan)啟動充(chong)(chong)(chong)電(dian)(dian)(dian)10小時(shi)以上，電(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)壓仍不能充(chong)(chong)(chong)電(dian)(dian)(dian)。故(gu)障(zhang)分析：從(cong)現象判(pan)斷(duan)為電(dian)(dian)(dian)池(chi)(chi)(chi)或充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)路故(gu)障(zhang)，可按以下(xia)步(bu)驟(zou)檢查(cha)：①檢查(cha)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)路輸入(ru)輸出電(dian)(dian)(dian)壓是否(fou)正常；②如(ru)果充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)路輸入(ru)正常，輸出異常，斷(duan)開電(dian)(dian)(dian)池(chi)(chi)(chi)再量，若仍不正常則為充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)路故(gu)障(zhang)；③如(ru)果電(dian)(dian)(dian)池(chi)(chi)(chi)斷(duan)開后充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)路輸入(ru)，輸出正常，則電(dian)(dian)(dian)池(chi)(chi)(chi)因長(chang)期未充(chong)(chong)(chong)電(dian)(dian)(dian)、過度放電(dian)(dian)(dian)或已達到使用(yong)壽命而(er)損壞(huai)。

常見問題四：

UPS電(dian)(dian)(dian)(dian)(dian)源啟動(dong)后，面板(ban)上沒有顯示(shi)，UPS電(dian)(dian)(dian)(dian)(dian)源不(bu)工作(zuo)。故障(zhang)分(fen)析(xi)：從故障(zhang)現象判斷，故障(zhang)在市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)輸入、蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)及市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)檢(jian)(jian)測(ce)(ce)部分(fen)及蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓檢(jian)(jian)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)路：①檢(jian)(jian)查(cha)(cha)市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)輸入保險(xian)(xian)絲是否(fou)燒毀；②如(ru)果(guo)市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)輸入保險(xian)(xian)絲完好，檢(jian)(jian)查(cha)(cha)電(dian)(dian)(dian)(dian)(dian)池(chi)保險(xian)(xian)是否(fou)燒毀，因為(wei)有些電(dian)(dian)(dian)(dian)(dian)池(chi)保險(xian)(xian)因為(wei)UPS當自檢(jian)(jian)不(bu)到電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓時(shi)，會UPS所(suo)有輸出輸出和顯示(shi)；③如(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)池(chi)保險(xian)(xian)完好，檢(jian)(jian)查(cha)(cha)市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)檢(jian)(jian)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)路工作(zuo)是否(fou)正(zheng)常，如(ru)果(guo)市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)檢(jian)(jian)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)路工作(zuo)異常，UPS無市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)啟動(dong)功(gong)能(neng)時(shi)，UPS所(suo)有輸出和顯示(shi)也將(jiang)關閉。④如(ru)果(guo)城市(shi)(shi)檢(jian)(jian)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)路工作(zuo)正(zheng)常，檢(jian)(jian)查(cha)(cha)電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓檢(jian)(jian)測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)路是否(fou)正(zheng)常。以上是介紹給大(da)家的。UPS希望常見的問(wen)題和維修技巧能(neng)對大(da)家有所(suo)幫(bang)助，但(dan)為(wei)了保險(xian)(xian)起見，大(da)家都會遇到，UPS出現故障(zhang)時(shi)，還(huan)是要(yao)找專業的維修人員進(jin)行測(ce)(ce)試維修，以免發(fa)生(sheng)意(yi)外，損失嚴重。
