一、ups不間斷電源的作用

當(dang)正(zheng)(zheng)常交(jiao)流供(gong)電(dian)(dian)(dian)(dian)(dian)中斷時(shi)(shi)，將蓄電(dian)(dian)(dian)(dian)(dian)池輸(shu)出的(de)直流變換成交(jiao)流持續(xu)供(gong)電(dian)(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)(dian)源設(she)(she)備(bei)(bei)。主要用于(yu)給單臺計算機(ji)、計算機(ji)網絡系統(tong)或其它電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)子設(she)(she)備(bei)(bei)提供(gong)不間斷的(de)電(dian)(dian)(dian)(dian)(dian)力供(gong)應(ying)。當(dang)市(shi)電(dian)(dian)(dian)(dian)(dian)輸(shu)入正(zheng)(zheng)常時(shi)(shi)，UPS 將市(shi)電(dian)(dian)(dian)(dian)(dian)穩壓后供(gong)應(ying)給負載(zai)使用，此時(shi)(shi)的(de)UPS就(jiu)是一臺交(jiao)流市(shi)電(dian)(dian)(dian)(dian)(dian)穩壓器(qi)，同時(shi)(shi)它還向機(ji)內(nei)電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)；當(dang)市(shi)電(dian)(dian)(dian)(dian)(dian)中斷時(shi)(shi)， UPS 立(li)即將機(ji)內(nei)電(dian)(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)(dian)能，通(tong)過(guo)逆變轉換的(de)方法向負載(zai)繼續(xu)供(gong)應(ying)220V交(jiao)流電(dian)(dian)(dian)(dian)(dian)，使負載(zai)維持正(zheng)(zheng)常工作(zuo)并(bing)保(bao)護負載(zai)軟、硬(ying)件不受損壞。UPS 設(she)(she)備(bei)(bei)通(tong)常對電(dian)(dian)(dian)(dian)(dian)壓過(guo)大和電(dian)(dian)(dian)(dian)(dian)壓太低都(dou)提供(gong)保(bao)護。

二、ups不間斷電源能供電多久

UPS不間斷電(dian)源產(chan)品(pin)可(ke)以(yi)使用的(de)年(nian)限是多久(jiu)，這個根據不同的(de)ups不間斷電源品牌，質(zhi)量，售后服務(wu)，維保(bao)(bao)(bao)服務(wu)等因數(shu)決定，一般使用10年(nian)以(yi)上都有，質(zhi)保(bao)(bao)(bao)期一般是3-4年(nian)，維保(bao)(bao)(bao)可(ke)以(yi)購(gou)買年(nian)限。

UPS不間斷電(dian)(dian)(dian)(dian)源可以供(gong)(gong)電(dian)(dian)(dian)(dian)多(duo)久，這個又分為外(wai)置(zhi)電(dian)(dian)(dian)(dian)池和內置(zhi)電(dian)(dian)(dian)(dian)池，內置(zhi)電(dian)(dian)(dian)(dian)池的UPS電(dian)(dian)(dian)(dian)源一般是標(biao)準機，標(biao)準供(gong)(gong)電(dian)(dian)(dian)(dian)時(shi)間3分鐘左(zuo)右，外(wai)置(zhi)電(dian)(dian)(dian)(dian)池是根據您的供(gong)(gong)電(dian)(dian)(dian)(dian)需求，進(jin)行額外(wai)增加(jia)，可以配置(zhi)供(gong)(gong)電(dian)(dian)(dian)(dian)時(shi)間達到23小時(shi)左(zuo)右。

另(ling)外，UPS不(bu)間斷電源能供電多這取決于(yu)運(yun)行(xing)的環(huan)境，維護和保養的情(qing)況，公司對舊UPS的態(tai)度，如果低效、容量不(bu)夠，運(yun)行(xing)環(huan)境差，如溫度過(guo)高、灰層太大、潮濕等(deng)等(deng)都會減短UPS的壽命，維護和保養不(bu)到位，也會縮(suo)短UPS的壽命。

正常(chang)的(de)來說，UPS電源的(de)使(shi)用(yong)壽命一(yi)般都可(ke)以達到8-10年，而維(wei)護得當的(de)UPS電源這可(ke)以使(shi)用(yong)15年以上(shang)，像美國(guo)很多地方(fang)的(de)數據中心都用(yong)了20年上(shang)下，里(li)面的(de)UPS電源也從來沒有更(geng)換過(guo)。

小(xiao)型家用電腦(nao)UPS不(bu)間(jian)斷電源時間(jian)一(yi)般(ban)能維(wei)持20分鐘。大型千(qian)瓦(wa)級別UPS可根(gen)據要求設置電池組(zu)，一(yi)般(ban)1個小(xiao)時以上到10個小(xiao)時。

三、ups不間斷電源維修

其余正(zheng)(zheng)常，但是(shi)無逆(ni)變跡(ji)象(xiang)，由(you)此懷疑是(shi)某IC損壞(huai)，更(geng)換(huan)即可(ke)。開機(ji)(ji)不(bu)反應，不(bu)工作，最常見(jian)的(de)原因是(shi)機(ji)(ji)內(nei)低壓(ya)電(dian)(dian)(dian)(dian)路的(de)供電(dian)(dian)(dian)(dian)不(bu)正(zheng)(zheng)常，而(er)這種(zhong)供電(dian)(dian)(dian)(dian)不(bu)正(zheng)(zheng)常一般是(shi)因機(ji)(ji)內(nei)電(dian)(dian)(dian)(dian)瓶(ping)損壞(huai)、低壓(ya)保險絲損壞(huai)引起。電(dian)(dian)(dian)(dian)瓶(ping)兩端僅(jin)有不(bu)足(zu)5v的(de)電(dian)(dian)(dian)(dian)壓(ya)，用新電(dian)(dian)(dian)(dian)瓶(ping)替換(huan)，將電(dian)(dian)(dian)(dian)源(yuan)插(cha)頭插(cha)入市(shi)電(dian)(dian)(dian)(dian)，開機(ji)(ji)后立刻正(zheng)(zheng)常。說明是(shi)假性(xing)損壞(huai)，屬于自然放電(dian)(dian)(dian)(dian)導(dao)致。
