一、ups不間斷電源的作用

當(dang)正(zheng)常(chang)(chang)交流(liu)(liu)供(gong)(gong)(gong)(gong)電(dian)中(zhong)斷時(shi)，將蓄電(dian)池輸出(chu)的(de)(de)直流(liu)(liu)變換成交流(liu)(liu)持續(xu)供(gong)(gong)(gong)(gong)電(dian)的(de)(de)電(dian)源設(she)備(bei)。主要用(yong)于給單臺計算(suan)機、計算(suan)機網絡系統或其它電(dian)力電(dian)子設(she)備(bei)提(ti)供(gong)(gong)(gong)(gong)不(bu)間斷的(de)(de)電(dian)力供(gong)(gong)(gong)(gong)應(ying)。當(dang)市(shi)電(dian)輸入(ru)正(zheng)常(chang)(chang)時(shi)，UPS 將市(shi)電(dian)穩壓后供(gong)(gong)(gong)(gong)應(ying)給負(fu)載使用(yong)，此時(shi)的(de)(de)UPS就是一臺交流(liu)(liu)市(shi)電(dian)穩壓器(qi)，同時(shi)它還向機內電(dian)池充電(dian)；當(dang)市(shi)電(dian)中(zhong)斷時(shi)， UPS 立即將機內電(dian)池的(de)(de)電(dian)能，通(tong)過逆變轉(zhuan)換的(de)(de)方法向負(fu)載繼續(xu)供(gong)(gong)(gong)(gong)應(ying)220V交流(liu)(liu)電(dian)，使負(fu)載維持正(zheng)常(chang)(chang)工作并保(bao)護(hu)(hu)負(fu)載軟、硬(ying)件(jian)不(bu)受損壞。UPS 設(she)備(bei)通(tong)常(chang)(chang)對電(dian)壓過大和電(dian)壓太低都提(ti)供(gong)(gong)(gong)(gong)保(bao)護(hu)(hu)。

二、ups不間斷電源能供電多久

UPS不(bu)間斷電源產品可以使(shi)用的年限是多久，這個根據不(bu)同的ups不間斷電源品牌，質量，售后服(fu)務(wu)，維保(bao)服(fu)務(wu)等因(yin)數決定(ding)，一般使用(yong)10年以上都(dou)有，質保(bao)期一般是(shi)3-4年，維保(bao)可以購(gou)買年限。

UPS不(bu)間斷(duan)電(dian)(dian)(dian)源(yuan)可以供(gong)(gong)(gong)電(dian)(dian)(dian)多久，這(zhe)個(ge)又分為外置電(dian)(dian)(dian)池(chi)和內(nei)置電(dian)(dian)(dian)池(chi)，內(nei)置電(dian)(dian)(dian)池(chi)的UPS電(dian)(dian)(dian)源(yuan)一般是標準機(ji)，標準供(gong)(gong)(gong)電(dian)(dian)(dian)時間3分鐘左右，外置電(dian)(dian)(dian)池(chi)是根據您(nin)的供(gong)(gong)(gong)電(dian)(dian)(dian)需求，進行額外增(zeng)加，可以配置供(gong)(gong)(gong)電(dian)(dian)(dian)時間達到23小時左右。

另外，UPS不(bu)間斷電源能供電多這(zhe)取決(jue)于(yu)運(yun)行的環(huan)(huan)境(jing)，維(wei)護和保(bao)養的情況，公司對舊UPS的態度(du)，如果低(di)效(xiao)、容量不(bu)夠，運(yun)行環(huan)(huan)境(jing)差，如溫度(du)過高、灰層太大、潮濕等等都會(hui)減短UPS的壽(shou)命(ming)，維(wei)護和保(bao)養不(bu)到位，也會(hui)縮短UPS的壽(shou)命(ming)。

正(zheng)常的(de)來說，UPS電源(yuan)的(de)使用(yong)(yong)壽命一般都(dou)可以(yi)達到8-10年(nian)，而維護得當(dang)的(de)UPS電源(yuan)這(zhe)可以(yi)使用(yong)(yong)15年(nian)以(yi)上(shang)，像美國很多地方的(de)數據中心都(dou)用(yong)(yong)了20年(nian)上(shang)下，里面(mian)的(de)UPS電源(yuan)也從(cong)來沒有更換過。

小(xiao)型家用(yong)電(dian)腦UPS不間斷電(dian)源時間一般能維持(chi)20分(fen)鐘。大型千瓦(wa)級別UPS可根據要求設置電(dian)池組，一般1個小(xiao)時以上(shang)到10個小(xiao)時。

三、ups不間斷電源維修

其余正常，但是(shi)(shi)(shi)無逆變(bian)跡象，由(you)此懷(huai)疑是(shi)(shi)(shi)某IC損(sun)壞(huai)(huai)，更換即(ji)可。開機不反(fan)應，不工作，最常見的原因(yin)是(shi)(shi)(shi)機內低(di)壓(ya)(ya)電(dian)(dian)(dian)路(lu)的供電(dian)(dian)(dian)不正常，而這種(zhong)供電(dian)(dian)(dian)不正常一般(ban)是(shi)(shi)(shi)因(yin)機內電(dian)(dian)(dian)瓶損(sun)壞(huai)(huai)、低(di)壓(ya)(ya)保險絲損(sun)壞(huai)(huai)引起。電(dian)(dian)(dian)瓶兩端僅有不足(zu)5v的電(dian)(dian)(dian)壓(ya)(ya)，用新電(dian)(dian)(dian)瓶替換，將電(dian)(dian)(dian)源插頭插入(ru)市(shi)電(dian)(dian)(dian)，開機后立刻正常。說明是(shi)(shi)(shi)假性損(sun)壞(huai)(huai)，屬于自然放電(dian)(dian)(dian)導致。
