一、ups不間斷電源的作用
當(dang)正(zheng)常交(jiao)(jiao)流(liu)(liu)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)中斷時(shi)(shi)，將蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池輸(shu)出的(de)(de)(de)直流(liu)(liu)變(bian)(bian)換成交(jiao)(jiao)流(liu)(liu)持(chi)續(xu)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源設(she)(she)備。主要用于給(gei)單臺計算機、計算機網絡(luo)系統(tong)或其(qi)它(ta)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設(she)(she)備提供(gong)(gong)(gong)不間斷的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)供(gong)(gong)(gong)應。當(dang)市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)輸(shu)入正(zheng)常時(shi)(shi)，UPS 將市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)穩(wen)壓(ya)后供(gong)(gong)(gong)應給(gei)負(fu)載(zai)使用，此(ci)時(shi)(shi)的(de)(de)(de)UPS就(jiu)是一臺交(jiao)(jiao)流(liu)(liu)市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)穩(wen)壓(ya)器，同時(shi)(shi)它(ta)還向(xiang)機內電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)；當(dang)市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)中斷時(shi)(shi)， UPS 立即將機內電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能，通過(guo)逆(ni)變(bian)(bian)轉換的(de)(de)(de)方法向(xiang)負(fu)載(zai)繼續(xu)供(gong)(gong)(gong)應220V交(jiao)(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，使負(fu)載(zai)維持(chi)正(zheng)常工作并(bing)保護(hu)(hu)負(fu)載(zai)軟、硬件不受損壞。UPS 設(she)(she)備通常對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)過(guo)大和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)太(tai)低都提供(gong)(gong)(gong)保護(hu)(hu)。
二、ups不間斷電源能供電多久
UPS不間斷電源產品可以使用的年(nian)限是多久，這個(ge)根據不同的ups不間斷電源品牌，質量，售后服(fu)務，維保(bao)服(fu)務等因數決定(ding)，一(yi)般使用10年以上都有，質保(bao)期一(yi)般是(shi)3-4年，維保(bao)可以購買年限。
UPS不間斷電(dian)源(yuan)(yuan)可(ke)以(yi)供電(dian)多(duo)久，這(zhe)個(ge)又分(fen)為外置(zhi)電(dian)池和內置(zhi)電(dian)池，內置(zhi)電(dian)池的UPS電(dian)源(yuan)(yuan)一般是(shi)標準機，標準供電(dian)時間3分(fen)鐘左右，外置(zhi)電(dian)池是(shi)根據(ju)您的供電(dian)需求，進行額外增加(jia)，可(ke)以(yi)配置(zhi)供電(dian)時間達(da)到23小時左右。
另外，UPS不間斷電源能(neng)供電多(duo)這取決(jue)于運行的環境，維護和保養的情況，公(gong)司(si)對(dui)舊UPS的態度，如(ru)果(guo)低效、容量不夠(gou)，運行環境差，如(ru)溫度過高(gao)、灰層太大、潮濕等(deng)等(deng)都會(hui)減短(duan)UPS的壽命，維護和保養不到位，也會(hui)縮短(duan)UPS的壽命。
正常(chang)的來(lai)說，UPS電源(yuan)(yuan)的使用(yong)壽命(ming)一般都可以達到8-10年，而(er)維護(hu)得(de)當的UPS電源(yuan)(yuan)這可以使用(yong)15年以上(shang)，像美國很多地方的數據(ju)中心(xin)都用(yong)了20年上(shang)下(xia)，里面的UPS電源(yuan)(yuan)也(ye)從(cong)來(lai)沒有更換(huan)過。
小(xiao)型(xing)家用電(dian)腦UPS不(bu)間斷電(dian)源時間一(yi)般能維持(chi)20分鐘。大型(xing)千瓦(wa)級別UPS可根據要求設(she)置電(dian)池組(zu)，一(yi)般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)常(chang)(chang)，但是(shi)無逆變跡(ji)象，由(you)此懷(huai)疑是(shi)某IC損(sun)壞(huai)，更(geng)換即可。開(kai)(kai)機不(bu)反應，不(bu)工作，最常(chang)(chang)見的原因(yin)是(shi)機內低(di)壓(ya)(ya)(ya)電(dian)路的供(gong)電(dian)不(bu)正(zheng)常(chang)(chang)，而這種供(gong)電(dian)不(bu)正(zheng)常(chang)(chang)一般是(shi)因(yin)機內電(dian)瓶(ping)損(sun)壞(huai)、低(di)壓(ya)(ya)(ya)保險絲損(sun)壞(huai)引起(qi)。電(dian)瓶(ping)兩端僅有不(bu)足5v的電(dian)壓(ya)(ya)(ya)，用新電(dian)瓶(ping)替換，將(jiang)電(dian)源插頭插入市電(dian)，開(kai)(kai)機后立刻正(zheng)常(chang)(chang)。說明是(shi)假(jia)性(xing)損(sun)壞(huai)，屬于自然放(fang)電(dian)導致。
