一、ups不間斷電源的作用

當正(zheng)常交(jiao)流(liu)供(gong)(gong)(gong)電(dian)(dian)(dian)中斷(duan)時(shi)，將(jiang)蓄電(dian)(dian)(dian)池輸(shu)出的直(zhi)流(liu)變換(huan)成交(jiao)流(liu)持續(xu)供(gong)(gong)(gong)電(dian)(dian)(dian)的電(dian)(dian)(dian)源設備(bei)。主(zhu)要(yao)用(yong)于給單臺(tai)計算機、計算機網絡系統或其它(ta)電(dian)(dian)(dian)力電(dian)(dian)(dian)子(zi)設備(bei)提(ti)(ti)供(gong)(gong)(gong)不間斷(duan)的電(dian)(dian)(dian)力供(gong)(gong)(gong)應。當市電(dian)(dian)(dian)輸(shu)入正(zheng)常時(shi)，UPS 將(jiang)市電(dian)(dian)(dian)穩壓(ya)(ya)后供(gong)(gong)(gong)應給負(fu)載(zai)使用(yong)，此(ci)時(shi)的UPS就是一臺(tai)交(jiao)流(liu)市電(dian)(dian)(dian)穩壓(ya)(ya)器，同時(shi)它(ta)還向機內(nei)(nei)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)；當市電(dian)(dian)(dian)中斷(duan)時(shi)， UPS 立即將(jiang)機內(nei)(nei)電(dian)(dian)(dian)池的電(dian)(dian)(dian)能，通過逆(ni)變轉換(huan)的方法向負(fu)載(zai)繼(ji)續(xu)供(gong)(gong)(gong)應220V交(jiao)流(liu)電(dian)(dian)(dian)，使負(fu)載(zai)維持正(zheng)常工作并保護(hu)負(fu)載(zai)軟、硬(ying)件不受損(sun)壞。UPS 設備(bei)通常對電(dian)(dian)(dian)壓(ya)(ya)過大和電(dian)(dian)(dian)壓(ya)(ya)太(tai)低都(dou)提(ti)(ti)供(gong)(gong)(gong)保護(hu)。

二、ups不間斷電源能供電多久

UPS不(bu)間斷(duan)電(dian)源產(chan)品(pin)可以使用的年限是(shi)多久，這個根據不(bu)同的ups不間斷電源品牌，質(zhi)量(liang)，售后服務(wu)，維保(bao)服務(wu)等因數(shu)決定，一(yi)般(ban)使用10年(nian)以(yi)上都有，質(zhi)保(bao)期一(yi)般(ban)是3-4年(nian)，維保(bao)可以(yi)購買年(nian)限(xian)。

UPS不間斷電(dian)(dian)源(yuan)(yuan)可以供電(dian)(dian)多久，這個又分(fen)(fen)為(wei)外(wai)(wai)置電(dian)(dian)池和內(nei)置電(dian)(dian)池，內(nei)置電(dian)(dian)池的UPS電(dian)(dian)源(yuan)(yuan)一般是標準機，標準供電(dian)(dian)時(shi)(shi)間3分(fen)(fen)鐘(zhong)左右(you)，外(wai)(wai)置電(dian)(dian)池是根據您的供電(dian)(dian)需(xu)求(qiu)，進行額外(wai)(wai)增加，可以配置供電(dian)(dian)時(shi)(shi)間達(da)到23小時(shi)(shi)左右(you)。

另外，UPS不間斷電源能供電多(duo)這取決于運行的環境，維(wei)(wei)護(hu)和保養的情況，公(gong)司(si)對舊UPS的態度(du)，如果(guo)低效(xiao)、容量不夠(gou)，運行環境差，如溫度(du)過高、灰層(ceng)太大、潮濕等等都(dou)會減短UPS的壽命，維(wei)(wei)護(hu)和保養不到(dao)位，也會縮短UPS的壽命。

正(zheng)常的(de)(de)來說(shuo)，UPS電源的(de)(de)使(shi)用(yong)壽命一般都可以達(da)到8-10年，而維護得當的(de)(de)UPS電源這可以使(shi)用(yong)15年以上，像(xiang)美國很多地(di)方(fang)的(de)(de)數(shu)據中心都用(yong)了20年上下(xia)，里面的(de)(de)UPS電源也從來沒有更換過。

小(xiao)型家用電腦UPS不(bu)間斷電源時(shi)(shi)間一(yi)般能維持20分鐘。大型千瓦級別UPS可根據(ju)要(yao)求(qiu)設置電池組(zu)，一(yi)般1個小(xiao)時(shi)(shi)以(yi)上到10個小(xiao)時(shi)(shi)。

三、ups不間斷電源維修

其(qi)余正(zheng)(zheng)常(chang)，但是(shi)(shi)無(wu)逆變(bian)跡象(xiang)，由此懷疑是(shi)(shi)某IC損(sun)壞(huai)，更換(huan)即(ji)可。開(kai)機(ji)(ji)不(bu)反應，不(bu)工作，最(zui)常(chang)見的原因是(shi)(shi)機(ji)(ji)內低壓電(dian)(dian)路的供電(dian)(dian)不(bu)正(zheng)(zheng)常(chang)，而這種供電(dian)(dian)不(bu)正(zheng)(zheng)常(chang)一(yi)般是(shi)(shi)因機(ji)(ji)內電(dian)(dian)瓶損(sun)壞(huai)、低壓保(bao)險絲損(sun)壞(huai)引起。電(dian)(dian)瓶兩(liang)端僅有不(bu)足5v的電(dian)(dian)壓，用新電(dian)(dian)瓶替(ti)換(huan)，將電(dian)(dian)源插頭插入市電(dian)(dian)，開(kai)機(ji)(ji)后立刻正(zheng)(zheng)常(chang)。說明(ming)是(shi)(shi)假(jia)性損(sun)壞(huai)，屬于自然放電(dian)(dian)導致。
