一、ups不間斷電源的作用

當正(zheng)常(chang)交(jiao)流供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)中斷時(shi)(shi)，將(jiang)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池輸(shu)出的(de)直流變換成交(jiao)流持(chi)續供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源設(she)備(bei)(bei)。主(zhu)要用于(yu)給(gei)單臺(tai)計算機、計算機網(wang)絡(luo)系統或其它(ta)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設(she)備(bei)(bei)提供不間斷的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)供應(ying)。當市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)輸(shu)入正(zheng)常(chang)時(shi)(shi)，UPS 將(jiang)市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)穩壓(ya)后供應(ying)給(gei)負載(zai)(zai)使(shi)用，此時(shi)(shi)的(de)UPS就是一臺(tai)交(jiao)流市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)穩壓(ya)器，同時(shi)(shi)它(ta)還向機內電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)；當市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)中斷時(shi)(shi)， UPS 立即將(jiang)機內電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能，通過逆變轉換的(de)方法向負載(zai)(zai)繼續供應(ying)220V交(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，使(shi)負載(zai)(zai)維(wei)持(chi)正(zheng)常(chang)工作并保護(hu)負載(zai)(zai)軟、硬(ying)件(jian)不受損(sun)壞(huai)。UPS 設(she)備(bei)(bei)通常(chang)對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)過大和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)太低都提供保護(hu)。

二、ups不間斷電源能供電多久

UPS不間斷電源產品可(ke)以使(shi)用的(de)年限(xian)是多久，這個根據不同的(de)ups不間斷電源品牌，質量，售后服(fu)務(wu)，維(wei)保服(fu)務(wu)等(deng)因數決定(ding)，一(yi)般使用(yong)10年以上都有(you)，質保期一(yi)般是3-4年，維(wei)保可以購(gou)買(mai)年限。

UPS不間斷電(dian)(dian)源可以供電(dian)(dian)多久，這個又分為(wei)外置電(dian)(dian)池(chi)和(he)內置電(dian)(dian)池(chi)，內置電(dian)(dian)池(chi)的UPS電(dian)(dian)源一般是標(biao)準機(ji)，標(biao)準供電(dian)(dian)時(shi)間3分鐘(zhong)左(zuo)右，外置電(dian)(dian)池(chi)是根據您的供電(dian)(dian)需求(qiu)，進行額外增加(jia)，可以配置供電(dian)(dian)時(shi)間達到23小(xiao)時(shi)左(zuo)右。

另外(wai)，UPS不(bu)間斷電源能(neng)供電多這(zhe)取決于運行的(de)環(huan)境(jing)，維護和保養的(de)情況，公司對舊UPS的(de)態(tai)度，如果低效、容(rong)量不(bu)夠(gou)，運行環(huan)境(jing)差，如溫度過高、灰(hui)層太大、潮(chao)濕等等都(dou)會減短UPS的(de)壽(shou)命，維護和保養不(bu)到位，也會縮(suo)短UPS的(de)壽(shou)命。

正常的來(lai)說，UPS電(dian)(dian)源(yuan)的使(shi)用壽命一般都可(ke)以(yi)達到(dao)8-10年(nian)，而(er)維護得當的UPS電(dian)(dian)源(yuan)這可(ke)以(yi)使(shi)用15年(nian)以(yi)上(shang)(shang)，像美國很多地方的數據中心都用了(le)20年(nian)上(shang)(shang)下，里面的UPS電(dian)(dian)源(yuan)也從來(lai)沒有(you)更換過。

小(xiao)型家用電(dian)(dian)腦UPS不間斷電(dian)(dian)源時間一(yi)般能(neng)維持20分鐘。大型千瓦級別UPS可根據要求設(she)置電(dian)(dian)池(chi)組(zu)，一(yi)般1個(ge)小(xiao)時以上到(dao)10個(ge)小(xiao)時。

三、ups不間斷電源維修

其(qi)余正常，但(dan)是(shi)(shi)無逆變跡象(xiang)，由此懷疑(yi)是(shi)(shi)某IC損(sun)壞(huai)(huai)，更換(huan)即(ji)可。開(kai)機(ji)不(bu)(bu)反應，不(bu)(bu)工作，最常見的(de)原因(yin)是(shi)(shi)機(ji)內(nei)低壓電(dian)路的(de)供電(dian)不(bu)(bu)正常，而這種供電(dian)不(bu)(bu)正常一般(ban)是(shi)(shi)因(yin)機(ji)內(nei)電(dian)瓶(ping)損(sun)壞(huai)(huai)、低壓保險(xian)絲損(sun)壞(huai)(huai)引起。電(dian)瓶(ping)兩(liang)端僅有(you)不(bu)(bu)足(zu)5v的(de)電(dian)壓，用(yong)新電(dian)瓶(ping)替(ti)換(huan)，將電(dian)源(yuan)插(cha)頭插(cha)入(ru)市(shi)電(dian)，開(kai)機(ji)后(hou)立刻正常。說明是(shi)(shi)假性損(sun)壞(huai)(huai)，屬于自然(ran)放電(dian)導(dao)致。
