一、ups不間斷電源的作用

當正常(chang)交(jiao)流供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)中斷時，將(jiang)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)輸出的直流變換(huan)成(cheng)交(jiao)流持續供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源設備。主(zhu)要用于(yu)給單(dan)臺(tai)計(ji)算(suan)機、計(ji)算(suan)機網(wang)絡系統或其它電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設備提(ti)供(gong)(gong)不間斷的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力供(gong)(gong)應。當市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)輸入正常(chang)時，UPS 將(jiang)市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)穩(wen)壓后供(gong)(gong)應給負(fu)載使用，此時的UPS就是一臺(tai)交(jiao)流市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)穩(wen)壓器，同時它還向(xiang)機內電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)；當市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)中斷時， UPS 立即(ji)將(jiang)機內電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)，通過(guo)逆變轉換(huan)的方法向(xiang)負(fu)載繼續供(gong)(gong)應220V交(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，使負(fu)載維持正常(chang)工作(zuo)并保護(hu)負(fu)載軟、硬件不受損壞。UPS 設備通常(chang)對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓過(guo)大和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓太低都提(ti)供(gong)(gong)保護(hu)。

二、ups不間斷電源能供電多久

UPS不(bu)間斷電(dian)源(yuan)產品可以使用的(de)(de)年限(xian)是多久，這(zhe)個根(gen)據不(bu)同的(de)(de)ups不間斷電源品牌，質量，售(shou)后服務，維保(bao)服務等因數決定(ding)，一般(ban)使用10年(nian)(nian)以上都(dou)有，質保(bao)期一般(ban)是3-4年(nian)(nian)，維保(bao)可以購買年(nian)(nian)限(xian)。

UPS不間斷電源可(ke)以(yi)供(gong)電多久，這個又(you)分(fen)(fen)為外置(zhi)電池(chi)(chi)和內置(zhi)電池(chi)(chi)，內置(zhi)電池(chi)(chi)的UPS電源一般(ban)是標準(zhun)機(ji)，標準(zhun)供(gong)電時(shi)間3分(fen)(fen)鐘左右(you)，外置(zhi)電池(chi)(chi)是根據您的供(gong)電需求(qiu)，進行額外增加，可(ke)以(yi)配置(zhi)供(gong)電時(shi)間達到23小時(shi)左右(you)。

另外，UPS不(bu)(bu)間斷電源能供電多(duo)這(zhe)取決于運行的(de)環境，維護(hu)和(he)保養(yang)的(de)情況，公司對(dui)舊UPS的(de)態度(du)，如果低效、容量不(bu)(bu)夠，運行環境差，如溫度(du)過高、灰層(ceng)太大、潮濕等等都會(hui)減短UPS的(de)壽(shou)命(ming)(ming)，維護(hu)和(he)保養(yang)不(bu)(bu)到位，也會(hui)縮(suo)短UPS的(de)壽(shou)命(ming)(ming)。

正(zheng)常的來說，UPS電源的使用(yong)壽命一般(ban)都(dou)可(ke)以達(da)到(dao)8-10年，而維護得當的UPS電源這可(ke)以使用(yong)15年以上，像(xiang)美國(guo)很多地方的數據中心都(dou)用(yong)了20年上下，里面的UPS電源也從(cong)來沒有更換過(guo)。

小型家(jia)用(yong)電腦UPS不間(jian)斷電源時(shi)間(jian)一(yi)般能維持20分(fen)鐘。大型千(qian)瓦級別UPS可根據要求(qiu)設(she)置電池組，一(yi)般1個(ge)小時(shi)以上到(dao)10個(ge)小時(shi)。

三、ups不間斷電源維修

其(qi)余正常(chang)，但是無逆(ni)變(bian)跡(ji)象，由此懷疑是某IC損(sun)壞(huai)，更換(huan)即可。開機不(bu)反應，不(bu)工作，最常(chang)見的(de)原因是機內低(di)(di)壓(ya)電(dian)(dian)(dian)(dian)路(lu)的(de)供(gong)電(dian)(dian)(dian)(dian)不(bu)正常(chang)，而(er)這種供(gong)電(dian)(dian)(dian)(dian)不(bu)正常(chang)一般是因機內電(dian)(dian)(dian)(dian)瓶損(sun)壞(huai)、低(di)(di)壓(ya)保險絲損(sun)壞(huai)引起。電(dian)(dian)(dian)(dian)瓶兩端僅有不(bu)足(zu)5v的(de)電(dian)(dian)(dian)(dian)壓(ya)，用新(xin)電(dian)(dian)(dian)(dian)瓶替換(huan)，將電(dian)(dian)(dian)(dian)源插頭插入市電(dian)(dian)(dian)(dian)，開機后(hou)立(li)刻正常(chang)。說明是假性損(sun)壞(huai)，屬于自(zi)然(ran)放電(dian)(dian)(dian)(dian)導致(zhi)。
