一、ups不間斷電源的作用
當正(zheng)常(chang)交流(liu)(liu)(liu)供(gong)電(dian)(dian)(dian)(dian)(dian)中斷時(shi)，將(jiang)蓄電(dian)(dian)(dian)(dian)(dian)池輸出的直(zhi)流(liu)(liu)(liu)變換(huan)成(cheng)交流(liu)(liu)(liu)持(chi)續(xu)供(gong)電(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)源(yuan)設備。主(zhu)要用于給單臺(tai)計(ji)算(suan)機(ji)、計(ji)算(suan)機(ji)網絡系(xi)統或其它電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)子設備提供(gong)不間斷的電(dian)(dian)(dian)(dian)(dian)力(li)供(gong)應(ying)。當市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)輸入正(zheng)常(chang)時(shi)，UPS 將(jiang)市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)穩壓(ya)(ya)后供(gong)應(ying)給負(fu)載(zai)使用，此時(shi)的UPS就是(shi)一臺(tai)交流(liu)(liu)(liu)市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)穩壓(ya)(ya)器，同時(shi)它還(huan)向(xiang)機(ji)內(nei)電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)；當市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)中斷時(shi)， UPS 立即將(jiang)機(ji)內(nei)電(dian)(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(dian)(dian)能，通過逆變轉換(huan)的方法向(xiang)負(fu)載(zai)繼續(xu)供(gong)應(ying)220V交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，使負(fu)載(zai)維持(chi)正(zheng)常(chang)工作并保護負(fu)載(zai)軟、硬件不受損(sun)壞。UPS 設備通常(chang)對(dui)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)過大和(he)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)太(tai)低都(dou)提供(gong)保護。
二、ups不間斷電源能供電多久
UPS不間斷(duan)電源產品可以(yi)使用的年限(xian)是多久(jiu)，這個根(gen)據不同(tong)的ups不間斷電源品牌，質(zhi)量(liang)，售(shou)后(hou)服務，維保(bao)服務等因(yin)數決定，一般使用10年(nian)以(yi)上都有，質(zhi)保(bao)期一般是3-4年(nian)，維保(bao)可以(yi)購(gou)買年(nian)限。
UPS不間斷(duan)電(dian)(dian)源(yuan)可以供電(dian)(dian)多久，這個(ge)又分(fen)為外置(zhi)電(dian)(dian)池(chi)和(he)內置(zhi)電(dian)(dian)池(chi)，內置(zhi)電(dian)(dian)池(chi)的UPS電(dian)(dian)源(yuan)一般是(shi)標準機，標準供電(dian)(dian)時(shi)間3分(fen)鐘左右(you)，外置(zhi)電(dian)(dian)池(chi)是(shi)根據您的供電(dian)(dian)需求，進行額(e)外增(zeng)加，可以配置(zhi)供電(dian)(dian)時(shi)間達到23小時(shi)左右(you)。
另外，UPS不(bu)間斷(duan)電源能供電多(duo)這(zhe)取決(jue)于運行(xing)的(de)環(huan)境(jing)，維(wei)護和保(bao)養的(de)情況，公(gong)司對舊UPS的(de)態度，如果低效(xiao)、容量不(bu)夠，運行(xing)環(huan)境(jing)差，如溫度過高、灰層太(tai)大、潮濕(shi)等等都(dou)會(hui)減(jian)短UPS的(de)壽命(ming)，維(wei)護和保(bao)養不(bu)到位，也(ye)會(hui)縮短UPS的(de)壽命(ming)。
正(zheng)常(chang)的(de)(de)來說，UPS電(dian)(dian)源的(de)(de)使(shi)用壽命一般都可(ke)以達到8-10年，而(er)維護得當的(de)(de)UPS電(dian)(dian)源這可(ke)以使(shi)用15年以上，像美(mei)國(guo)很(hen)多(duo)地方的(de)(de)數(shu)據中心(xin)都用了20年上下，里(li)面的(de)(de)UPS電(dian)(dian)源也(ye)從來沒有更換過。
小型(xing)家用(yong)電腦UPS不間斷電源時(shi)間一般能維持(chi)20分(fen)鐘。大型(xing)千瓦級別UPS可(ke)根據(ju)要求設(she)置電池組(zu)，一般1個(ge)小時(shi)以上到10個(ge)小時(shi)。
三、ups不間斷電源維修
其余正(zheng)(zheng)常(chang)(chang)(chang)，但是無逆變(bian)跡象，由此懷疑是某IC損(sun)壞(huai)(huai)，更換即可。開機(ji)不(bu)反應，不(bu)工作，最常(chang)(chang)(chang)見(jian)的原因是機(ji)內低壓(ya)電(dian)(dian)路的供(gong)電(dian)(dian)不(bu)正(zheng)(zheng)常(chang)(chang)(chang)，而這種供(gong)電(dian)(dian)不(bu)正(zheng)(zheng)常(chang)(chang)(chang)一般是因機(ji)內電(dian)(dian)瓶(ping)損(sun)壞(huai)(huai)、低壓(ya)保險絲損(sun)壞(huai)(huai)引起。電(dian)(dian)瓶(ping)兩端(duan)僅(jin)有不(bu)足5v的電(dian)(dian)壓(ya)，用新電(dian)(dian)瓶(ping)替換，將電(dian)(dian)源(yuan)插頭插入市電(dian)(dian)，開機(ji)后(hou)立刻(ke)正(zheng)(zheng)常(chang)(chang)(chang)。說(shuo)明(ming)是假性損(sun)壞(huai)(huai)，屬于自然放電(dian)(dian)導致(zhi)。
