一、ups不間斷電源的作用

當正常(chang)交流(liu)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)中(zhong)斷(duan)(duan)時(shi)，將(jiang)蓄電(dian)(dian)(dian)(dian)(dian)池(chi)輸(shu)出的直流(liu)變換成交流(liu)持(chi)續(xu)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)源設(she)備。主要用(yong)于給單臺(tai)計(ji)算機、計(ji)算機網絡系統或其它電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)子設(she)備提供(gong)(gong)(gong)(gong)不間斷(duan)(duan)的電(dian)(dian)(dian)(dian)(dian)力(li)供(gong)(gong)(gong)(gong)應(ying)。當市電(dian)(dian)(dian)(dian)(dian)輸(shu)入正常(chang)時(shi)，UPS 將(jiang)市電(dian)(dian)(dian)(dian)(dian)穩壓后供(gong)(gong)(gong)(gong)應(ying)給負(fu)(fu)載(zai)使(shi)用(yong)，此時(shi)的UPS就是(shi)一臺(tai)交流(liu)市電(dian)(dian)(dian)(dian)(dian)穩壓器(qi)，同時(shi)它還向(xiang)機內電(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)；當市電(dian)(dian)(dian)(dian)(dian)中(zhong)斷(duan)(duan)時(shi)， UPS 立(li)即將(jiang)機內電(dian)(dian)(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)(dian)(dian)能，通過(guo)逆變轉換的方法向(xiang)負(fu)(fu)載(zai)繼續(xu)供(gong)(gong)(gong)(gong)應(ying)220V交流(liu)電(dian)(dian)(dian)(dian)(dian)，使(shi)負(fu)(fu)載(zai)維持(chi)正常(chang)工作并保護負(fu)(fu)載(zai)軟、硬件不受(shou)損壞。UPS 設(she)備通常(chang)對電(dian)(dian)(dian)(dian)(dian)壓過(guo)大和電(dian)(dian)(dian)(dian)(dian)壓太低都提供(gong)(gong)(gong)(gong)保護。

二、ups不間斷電源能供電多久

UPS不間斷電源產品(pin)可以(yi)使用的年(nian)限是多久(jiu)，這個根據不同的ups不間斷電源品牌，質量，售后服務(wu)，維(wei)(wei)保服務(wu)等因(yin)數決(jue)定，一(yi)般使用10年以上都有，質保期一(yi)般是3-4年，維(wei)(wei)保可以購買年限。

UPS不間斷電(dian)源(yuan)(yuan)可以(yi)供(gong)電(dian)多久，這(zhe)個(ge)又分(fen)為外(wai)置(zhi)電(dian)池(chi)和內置(zhi)電(dian)池(chi)，內置(zhi)電(dian)池(chi)的UPS電(dian)源(yuan)(yuan)一般是標準機(ji)，標準供(gong)電(dian)時(shi)間3分(fen)鐘左右(you)，外(wai)置(zhi)電(dian)池(chi)是根據您的供(gong)電(dian)需(xu)求，進(jin)行額外(wai)增加(jia)，可以(yi)配置(zhi)供(gong)電(dian)時(shi)間達(da)到23小時(shi)左右(you)。

另外，UPS不(bu)間(jian)斷電源能(neng)供電多這(zhe)取決于運行的環境(jing)，維(wei)護(hu)和(he)保養的情況，公司對(dui)舊UPS的態度，如(ru)果(guo)低效、容量不(bu)夠，運行環境(jing)差，如(ru)溫度過高、灰(hui)層(ceng)太大(da)、潮濕等(deng)(deng)等(deng)(deng)都會減短UPS的壽(shou)命，維(wei)護(hu)和(he)保養不(bu)到位，也會縮短UPS的壽(shou)命。

正常的(de)來說，UPS電(dian)源(yuan)的(de)使用(yong)壽(shou)命一般都(dou)可(ke)以(yi)達(da)到8-10年，而維護得(de)當的(de)UPS電(dian)源(yuan)這可(ke)以(yi)使用(yong)15年以(yi)上(shang)，像(xiang)美國很(hen)多地方的(de)數據(ju)中心都(dou)用(yong)了20年上(shang)下，里(li)面的(de)UPS電(dian)源(yuan)也從來沒有更(geng)換過。

小型(xing)家用電腦UPS不(bu)間(jian)斷(duan)電源時(shi)(shi)間(jian)一般能維持20分鐘。大(da)型(xing)千瓦級(ji)別(bie)UPS可(ke)根據要求(qiu)設置電池組，一般1個小時(shi)(shi)以上(shang)到10個小時(shi)(shi)。

三、ups不間斷電源維修

其余正常(chang)(chang)，但(dan)是(shi)無(wu)逆變(bian)跡象，由(you)此懷疑(yi)是(shi)某IC損(sun)(sun)壞，更換即可。開(kai)機(ji)不反應，不工作，最常(chang)(chang)見的原(yuan)因是(shi)機(ji)內低壓(ya)電(dian)(dian)路的供(gong)電(dian)(dian)不正常(chang)(chang)，而這種(zhong)供(gong)電(dian)(dian)不正常(chang)(chang)一般是(shi)因機(ji)內電(dian)(dian)瓶(ping)(ping)(ping)損(sun)(sun)壞、低壓(ya)保(bao)險(xian)絲(si)損(sun)(sun)壞引起。電(dian)(dian)瓶(ping)(ping)(ping)兩(liang)端僅有不足(zu)5v的電(dian)(dian)壓(ya)，用(yong)新電(dian)(dian)瓶(ping)(ping)(ping)替換，將(jiang)電(dian)(dian)源插頭插入市(shi)電(dian)(dian)，開(kai)機(ji)后立刻正常(chang)(chang)。說明是(shi)假性損(sun)(sun)壞，屬于(yu)自然放電(dian)(dian)導致。
