一、ups不間斷電源的作用

當正常交流(liu)供(gong)(gong)電(dian)(dian)(dian)中斷(duan)時(shi)，將蓄(xu)電(dian)(dian)(dian)池(chi)輸出的(de)直流(liu)變換成(cheng)交流(liu)持(chi)續供(gong)(gong)電(dian)(dian)(dian)的(de)電(dian)(dian)(dian)源設備。主要用(yong)于(yu)給單臺(tai)計算機(ji)、計算機(ji)網絡系(xi)統或其它電(dian)(dian)(dian)力電(dian)(dian)(dian)子設備提(ti)供(gong)(gong)不(bu)間斷(duan)的(de)電(dian)(dian)(dian)力供(gong)(gong)應。當市電(dian)(dian)(dian)輸入(ru)正常時(shi)，UPS 將市電(dian)(dian)(dian)穩(wen)壓(ya)(ya)后供(gong)(gong)應給負載(zai)使用(yong)，此(ci)時(shi)的(de)UPS就是一臺(tai)交流(liu)市電(dian)(dian)(dian)穩(wen)壓(ya)(ya)器，同時(shi)它還向(xiang)機(ji)內(nei)電(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)；當市電(dian)(dian)(dian)中斷(duan)時(shi)， UPS 立(li)即將機(ji)內(nei)電(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)能，通過逆變轉(zhuan)換的(de)方法向(xiang)負載(zai)繼(ji)續供(gong)(gong)應220V交流(liu)電(dian)(dian)(dian)，使負載(zai)維持(chi)正常工作并保護(hu)負載(zai)軟、硬件不(bu)受(shou)損壞(huai)。UPS 設備通常對(dui)電(dian)(dian)(dian)壓(ya)(ya)過大(da)和電(dian)(dian)(dian)壓(ya)(ya)太(tai)低(di)都提(ti)供(gong)(gong)保護(hu)。

二、ups不間斷電源能供電多久

UPS不(bu)間斷(duan)電源產品可以使用的年限是(shi)多久(jiu)，這個(ge)根據不(bu)同(tong)的ups不間斷電源品牌，質量，售后服務，維保服務等因數決定，一般使用10年(nian)以上都有，質保期一般是3-4年(nian)，維保可以購(gou)買年(nian)限。

UPS不間(jian)斷電(dian)(dian)(dian)(dian)源可以供電(dian)(dian)(dian)(dian)多久，這個又分(fen)為外置(zhi)(zhi)電(dian)(dian)(dian)(dian)池(chi)(chi)和(he)內置(zhi)(zhi)電(dian)(dian)(dian)(dian)池(chi)(chi)，內置(zhi)(zhi)電(dian)(dian)(dian)(dian)池(chi)(chi)的UPS電(dian)(dian)(dian)(dian)源一(yi)般是標(biao)準(zhun)機，標(biao)準(zhun)供電(dian)(dian)(dian)(dian)時間(jian)3分(fen)鐘左(zuo)右，外置(zhi)(zhi)電(dian)(dian)(dian)(dian)池(chi)(chi)是根據您的供電(dian)(dian)(dian)(dian)需求，進行額外增(zeng)加(jia)，可以配置(zhi)(zhi)供電(dian)(dian)(dian)(dian)時間(jian)達到23小時左(zuo)右。

另外，UPS不間(jian)斷電(dian)源能(neng)供電(dian)多這取決于運行(xing)的(de)(de)環境，維護和(he)保養的(de)(de)情況，公司對舊UPS的(de)(de)態度，如(ru)果低效(xiao)、容量不夠(gou)，運行(xing)環境差，如(ru)溫度過(guo)高、灰層太大、潮濕(shi)等等都會(hui)減短UPS的(de)(de)壽命(ming)，維護和(he)保養不到位，也會(hui)縮短UPS的(de)(de)壽命(ming)。

正常(chang)的(de)來(lai)(lai)說，UPS電(dian)源的(de)使(shi)用壽命(ming)一般都可以達到8-10年，而維(wei)護得當的(de)UPS電(dian)源這可以使(shi)用15年以上，像美國(guo)很多地方的(de)數據中心(xin)都用了20年上下，里面的(de)UPS電(dian)源也從(cong)來(lai)(lai)沒有更換過。

小型家用電(dian)腦UPS不間(jian)斷(duan)電(dian)源時(shi)間(jian)一般能維持20分鐘。大型千瓦(wa)級別UPS可根據要求設置電(dian)池組(zu)，一般1個小時(shi)以(yi)上到10個小時(shi)。

三、ups不間斷電源維修

其余正(zheng)常(chang)(chang)，但(dan)是(shi)無(wu)逆變跡象，由此懷疑是(shi)某IC損壞(huai)(huai)，更換(huan)即可(ke)。開機不(bu)(bu)(bu)反應，不(bu)(bu)(bu)工(gong)作(zuo)，最常(chang)(chang)見的原因(yin)是(shi)機內(nei)低壓(ya)電(dian)路的供(gong)電(dian)不(bu)(bu)(bu)正(zheng)常(chang)(chang)，而(er)這(zhe)種供(gong)電(dian)不(bu)(bu)(bu)正(zheng)常(chang)(chang)一般(ban)是(shi)因(yin)機內(nei)電(dian)瓶損壞(huai)(huai)、低壓(ya)保險絲損壞(huai)(huai)引起。電(dian)瓶兩端(duan)僅有不(bu)(bu)(bu)足(zu)5v的電(dian)壓(ya)，用新電(dian)瓶替換(huan)，將電(dian)源(yuan)插頭插入市(shi)電(dian)，開機后立刻(ke)正(zheng)常(chang)(chang)。說明是(shi)假(jia)性(xing)損壞(huai)(huai)，屬于自然(ran)放電(dian)導致。
