一、ups不間斷電源的作用

當(dang)(dang)正常(chang)交流(liu)供(gong)電(dian)(dian)(dian)(dian)中斷時(shi)，將蓄電(dian)(dian)(dian)(dian)池輸出的直(zhi)流(liu)變換成交流(liu)持(chi)續供(gong)電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)源設(she)備(bei)。主要用(yong)于給(gei)單(dan)臺計算(suan)機(ji)(ji)(ji)、計算(suan)機(ji)(ji)(ji)網絡系統(tong)或其它(ta)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)子設(she)備(bei)提供(gong)不間斷的電(dian)(dian)(dian)(dian)力供(gong)應(ying)。當(dang)(dang)市(shi)(shi)電(dian)(dian)(dian)(dian)輸入正常(chang)時(shi)，UPS 將市(shi)(shi)電(dian)(dian)(dian)(dian)穩壓(ya)后(hou)供(gong)應(ying)給(gei)負(fu)載(zai)(zai)使用(yong)，此時(shi)的UPS就是(shi)一臺交流(liu)市(shi)(shi)電(dian)(dian)(dian)(dian)穩壓(ya)器，同(tong)時(shi)它(ta)還向(xiang)機(ji)(ji)(ji)內(nei)電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)；當(dang)(dang)市(shi)(shi)電(dian)(dian)(dian)(dian)中斷時(shi)， UPS 立即將機(ji)(ji)(ji)內(nei)電(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(dian)能，通過逆變轉換的方(fang)法向(xiang)負(fu)載(zai)(zai)繼續供(gong)應(ying)220V交流(liu)電(dian)(dian)(dian)(dian)，使負(fu)載(zai)(zai)維持(chi)正常(chang)工作并保護負(fu)載(zai)(zai)軟、硬件不受損壞。UPS 設(she)備(bei)通常(chang)對電(dian)(dian)(dian)(dian)壓(ya)過大和電(dian)(dian)(dian)(dian)壓(ya)太低都提供(gong)保護。

二、ups不間斷電源能供電多久

UPS不間斷電源產品可(ke)以使用的年限是多久，這個根據不同的ups不間斷電源品牌，質(zhi)量，售后服務，維保(bao)服務等因數(shu)決定，一般使用10年以上都有，質(zhi)保(bao)期(qi)一般是3-4年，維保(bao)可以購(gou)買年限。

UPS不間(jian)斷(duan)電(dian)(dian)(dian)源(yuan)可(ke)以供(gong)電(dian)(dian)(dian)多久，這個(ge)又分(fen)為外置(zhi)電(dian)(dian)(dian)池(chi)和內置(zhi)電(dian)(dian)(dian)池(chi)，內置(zhi)電(dian)(dian)(dian)池(chi)的UPS電(dian)(dian)(dian)源(yuan)一般是(shi)標準機，標準供(gong)電(dian)(dian)(dian)時(shi)(shi)間(jian)3分(fen)鐘左右，外置(zhi)電(dian)(dian)(dian)池(chi)是(shi)根據(ju)您的供(gong)電(dian)(dian)(dian)需求，進行(xing)額外增加，可(ke)以配(pei)置(zhi)供(gong)電(dian)(dian)(dian)時(shi)(shi)間(jian)達到23小時(shi)(shi)左右。

另外，UPS不(bu)間斷(duan)電源能供電多這(zhe)取(qu)決(jue)于運行的(de)環(huan)境(jing)，維護(hu)和(he)保養(yang)的(de)情況(kuang)，公司(si)對舊(jiu)UPS的(de)態度(du)，如果低效、容量不(bu)夠，運行環(huan)境(jing)差，如溫(wen)度(du)過高、灰層太(tai)大、潮濕等等都會減(jian)短UPS的(de)壽命，維護(hu)和(he)保養(yang)不(bu)到位，也會縮短UPS的(de)壽命。

正常(chang)的來說，UPS電(dian)源(yuan)的使(shi)用(yong)壽命一般(ban)都可以達到8-10年(nian)，而維(wei)護得當的UPS電(dian)源(yuan)這(zhe)可以使(shi)用(yong)15年(nian)以上(shang)，像美國(guo)很多地(di)方(fang)的數據(ju)中心(xin)都用(yong)了20年(nian)上(shang)下，里(li)面的UPS電(dian)源(yuan)也從來沒有更換過。

小(xiao)(xiao)型家用電(dian)腦(nao)UPS不(bu)間斷電(dian)源(yuan)時間一(yi)般能維(wei)持20分鐘(zhong)。大型千瓦級別UPS可根據要求設(she)置(zhi)電(dian)池組，一(yi)般1個小(xiao)(xiao)時以上到10個小(xiao)(xiao)時。

三、ups不間斷電源維修

其余正(zheng)(zheng)常，但(dan)是(shi)(shi)無逆變跡(ji)象，由此懷疑是(shi)(shi)某IC損壞，更換(huan)即(ji)可。開(kai)機(ji)不(bu)反應，不(bu)工作，最常見的(de)原因是(shi)(shi)機(ji)內(nei)低(di)壓電(dian)路的(de)供(gong)電(dian)不(bu)正(zheng)(zheng)常，而這(zhe)種供(gong)電(dian)不(bu)正(zheng)(zheng)常一般是(shi)(shi)因機(ji)內(nei)電(dian)瓶(ping)損壞、低(di)壓保(bao)險絲損壞引起。電(dian)瓶(ping)兩端僅有不(bu)足5v的(de)電(dian)壓，用新電(dian)瓶(ping)替換(huan)，將電(dian)源插頭插入市電(dian)，開(kai)機(ji)后立(li)刻正(zheng)(zheng)常。說明是(shi)(shi)假(jia)性損壞，屬(shu)于自然放電(dian)導致。
