一、ups不間斷電源的作用

當正(zheng)常交(jiao)流(liu)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)中(zhong)斷時(shi)(shi)，將(jiang)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池輸(shu)出的直流(liu)變換成交(jiao)流(liu)持續供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)源(yuan)設備(bei)。主要用(yong)于給單臺計(ji)算(suan)機(ji)、計(ji)算(suan)機(ji)網(wang)絡系統(tong)或其它電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)子設備(bei)提供(gong)(gong)不(bu)間斷的電(dian)(dian)(dian)(dian)(dian)力(li)供(gong)(gong)應。當市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)輸(shu)入正(zheng)常時(shi)(shi)，UPS 將(jiang)市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)穩壓(ya)(ya)后供(gong)(gong)應給負載使用(yong)，此時(shi)(shi)的UPS就是(shi)一臺交(jiao)流(liu)市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)穩壓(ya)(ya)器(qi)，同(tong)時(shi)(shi)它還(huan)向機(ji)內電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)；當市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)中(zhong)斷時(shi)(shi)， UPS 立即將(jiang)機(ji)內電(dian)(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(dian)(dian)能，通過(guo)逆變轉(zhuan)換的方法向負載繼續供(gong)(gong)應220V交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)，使負載維持正(zheng)常工(gong)作(zuo)并保(bao)護負載軟(ruan)、硬件(jian)不(bu)受損壞。UPS 設備(bei)通常對電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)過(guo)大和電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)太低都提供(gong)(gong)保(bao)護。

二、ups不間斷電源能供電多久

UPS不(bu)(bu)間(jian)斷電源產品可以(yi)使用的(de)(de)年(nian)限(xian)是多久，這個根據不(bu)(bu)同的(de)(de)ups不間斷電源品牌，質(zhi)(zhi)量，售后服務，維(wei)保(bao)服務等因數決定(ding)，一般使用10年以上都有，質(zhi)(zhi)保(bao)期一般是3-4年，維(wei)保(bao)可以購買年限(xian)。

UPS不(bu)間斷電(dian)(dian)源(yuan)可以供電(dian)(dian)多久，這個又分(fen)為外(wai)置(zhi)電(dian)(dian)池(chi)和內(nei)置(zhi)電(dian)(dian)池(chi)，內(nei)置(zhi)電(dian)(dian)池(chi)的UPS電(dian)(dian)源(yuan)一般是(shi)標準(zhun)機，標準(zhun)供電(dian)(dian)時間3分(fen)鐘(zhong)左右，外(wai)置(zhi)電(dian)(dian)池(chi)是(shi)根據您的供電(dian)(dian)需求，進(jin)行額(e)外(wai)增加，可以配(pei)置(zhi)供電(dian)(dian)時間達到23小(xiao)時左右。

另外，UPS不間(jian)斷電(dian)源能(neng)供電(dian)多這取(qu)決于運(yun)行的環境，維護和保養(yang)的情(qing)況，公司(si)對舊UPS的態度(du)，如果低(di)效、容(rong)量(liang)不夠，運(yun)行環境差(cha)，如溫度(du)過高、灰層太大、潮濕等(deng)等(deng)都會減短UPS的壽(shou)(shou)命，維護和保養(yang)不到位，也會縮(suo)短UPS的壽(shou)(shou)命。

正常的來(lai)(lai)說，UPS電(dian)(dian)源的使(shi)用(yong)(yong)(yong)壽命一般(ban)都可以達到(dao)8-10年(nian)，而(er)維(wei)護(hu)得當的UPS電(dian)(dian)源這可以使(shi)用(yong)(yong)(yong)15年(nian)以上(shang)，像美國很多(duo)地方的數據中心都用(yong)(yong)(yong)了20年(nian)上(shang)下，里面的UPS電(dian)(dian)源也從來(lai)(lai)沒有(you)更換過。

小型(xing)家用電(dian)(dian)腦UPS不間(jian)斷電(dian)(dian)源時(shi)間(jian)一般能維持20分鐘(zhong)。大型(xing)千瓦級別UPS可(ke)根據(ju)要求設置電(dian)(dian)池組(zu)，一般1個小時(shi)以上(shang)到10個小時(shi)。

三、ups不間斷電源維修

其余正(zheng)常(chang)(chang)，但是(shi)(shi)無(wu)逆變跡(ji)象，由(you)此(ci)懷疑是(shi)(shi)某(mou)IC損(sun)壞(huai)(huai)，更換即可。開機(ji)不反應(ying)，不工(gong)作(zuo)，最(zui)常(chang)(chang)見的原因(yin)是(shi)(shi)機(ji)內(nei)低壓電(dian)路(lu)的供(gong)(gong)電(dian)不正(zheng)常(chang)(chang)，而這種供(gong)(gong)電(dian)不正(zheng)常(chang)(chang)一般是(shi)(shi)因(yin)機(ji)內(nei)電(dian)瓶(ping)損(sun)壞(huai)(huai)、低壓保險絲損(sun)壞(huai)(huai)引(yin)起。電(dian)瓶(ping)兩端僅(jin)有不足5v的電(dian)壓，用(yong)新電(dian)瓶(ping)替換，將(jiang)電(dian)源插(cha)頭(tou)插(cha)入(ru)市電(dian)，開機(ji)后立刻(ke)正(zheng)常(chang)(chang)。說明是(shi)(shi)假性損(sun)壞(huai)(huai)，屬于自然(ran)放電(dian)導致(zhi)。
