一、ups不間斷電源的作用

當正常(chang)交流供(gong)電(dian)(dian)(dian)中斷(duan)(duan)(duan)時(shi)(shi)，將蓄電(dian)(dian)(dian)池(chi)(chi)輸出(chu)的(de)直流變換成交流持續供(gong)電(dian)(dian)(dian)的(de)電(dian)(dian)(dian)源(yuan)設(she)備(bei)。主要(yao)用(yong)于給單(dan)臺(tai)計(ji)算機(ji)、計(ji)算機(ji)網絡系統(tong)或其它電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)子設(she)備(bei)提(ti)供(gong)不間斷(duan)(duan)(duan)的(de)電(dian)(dian)(dian)力(li)供(gong)應。當市電(dian)(dian)(dian)輸入(ru)正常(chang)時(shi)(shi)，UPS 將市電(dian)(dian)(dian)穩壓(ya)(ya)后供(gong)應給負(fu)(fu)載(zai)(zai)(zai)使用(yong)，此時(shi)(shi)的(de)UPS就是一臺(tai)交流市電(dian)(dian)(dian)穩壓(ya)(ya)器，同時(shi)(shi)它還向機(ji)內電(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)；當市電(dian)(dian)(dian)中斷(duan)(duan)(duan)時(shi)(shi)， UPS 立即(ji)將機(ji)內電(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)能(neng)，通過逆(ni)變轉換的(de)方(fang)法(fa)向負(fu)(fu)載(zai)(zai)(zai)繼續供(gong)應220V交流電(dian)(dian)(dian)，使負(fu)(fu)載(zai)(zai)(zai)維持正常(chang)工作并(bing)保護負(fu)(fu)載(zai)(zai)(zai)軟、硬件(jian)不受損壞。UPS 設(she)備(bei)通常(chang)對電(dian)(dian)(dian)壓(ya)(ya)過大和電(dian)(dian)(dian)壓(ya)(ya)太低都提(ti)供(gong)保護。

二、ups不間斷電源能供電多久

UPS不(bu)間斷電源產(chan)品(pin)可(ke)以(yi)使(shi)用的(de)年限是多(duo)久(jiu)，這(zhe)個根據不(bu)同的(de)ups不間斷電源品牌，質量(liang)，售后服(fu)務，維(wei)保服(fu)務等因數決定，一(yi)般(ban)使(shi)用10年以(yi)上都有，質保期(qi)一(yi)般(ban)是3-4年，維(wei)保可以(yi)購買(mai)年限。

UPS不(bu)間(jian)斷(duan)電(dian)源(yuan)可以(yi)供(gong)電(dian)多久，這(zhe)個又分為(wei)外置(zhi)電(dian)池(chi)和內置(zhi)電(dian)池(chi)，內置(zhi)電(dian)池(chi)的UPS電(dian)源(yuan)一(yi)般是標準(zhun)(zhun)機，標準(zhun)(zhun)供(gong)電(dian)時(shi)間(jian)3分鐘左(zuo)(zuo)右(you)，外置(zhi)電(dian)池(chi)是根據(ju)您的供(gong)電(dian)需求(qiu)，進行(xing)額外增加，可以(yi)配(pei)置(zhi)供(gong)電(dian)時(shi)間(jian)達到23小時(shi)左(zuo)(zuo)右(you)。

另外(wai)，UPS不(bu)間(jian)斷電(dian)源能供電(dian)多這取決(jue)于運(yun)行的(de)環(huan)境，維護(hu)和保養的(de)情況，公司對舊UPS的(de)態度(du)，如(ru)果低(di)效、容量(liang)不(bu)夠(gou)，運(yun)行環(huan)境差，如(ru)溫度(du)過高、灰層太大、潮(chao)濕等等都會減(jian)短UPS的(de)壽命(ming)，維護(hu)和保養不(bu)到位，也會縮短UPS的(de)壽命(ming)。

正常的(de)(de)來說，UPS電(dian)(dian)源的(de)(de)使用壽命一般都(dou)可以(yi)達到8-10年(nian)，而維(wei)護得當的(de)(de)UPS電(dian)(dian)源這可以(yi)使用15年(nian)以(yi)上，像美國很多(duo)地方的(de)(de)數據中(zhong)心(xin)都(dou)用了20年(nian)上下(xia)，里面的(de)(de)UPS電(dian)(dian)源也從來沒有更換(huan)過(guo)。

小型家用電(dian)腦(nao)UPS不(bu)間(jian)斷電(dian)源時間(jian)一(yi)般(ban)能維持(chi)20分(fen)鐘。大型千(qian)瓦級別(bie)UPS可根(gen)據要求設置電(dian)池組(zu)，一(yi)般(ban)1個(ge)小時以上到10個(ge)小時。

三、ups不間斷電源維修

其余正常(chang)(chang)，但(dan)是無(wu)逆變跡象，由此(ci)懷疑是某IC損壞，更換即可。開機不(bu)(bu)反應，不(bu)(bu)工作，最常(chang)(chang)見的原因是機內低壓電(dian)(dian)(dian)路的供電(dian)(dian)(dian)不(bu)(bu)正常(chang)(chang)，而這種(zhong)供電(dian)(dian)(dian)不(bu)(bu)正常(chang)(chang)一(yi)般(ban)是因機內電(dian)(dian)(dian)瓶(ping)(ping)損壞、低壓保險(xian)絲損壞引起。電(dian)(dian)(dian)瓶(ping)(ping)兩端僅有不(bu)(bu)足5v的電(dian)(dian)(dian)壓，用新電(dian)(dian)(dian)瓶(ping)(ping)替(ti)換，將電(dian)(dian)(dian)源插頭(tou)插入(ru)市電(dian)(dian)(dian)，開機后立(li)刻(ke)正常(chang)(chang)。說明是假性(xing)損壞，屬于自然放電(dian)(dian)(dian)導致。
