一、ups不間斷電源的作用

當(dang)正(zheng)(zheng)(zheng)常(chang)(chang)交(jiao)(jiao)流(liu)供(gong)(gong)電(dian)(dian)(dian)(dian)中斷(duan)(duan)(duan)時(shi)(shi)，將蓄電(dian)(dian)(dian)(dian)池(chi)輸(shu)出的(de)直(zhi)流(liu)變(bian)換(huan)成(cheng)交(jiao)(jiao)流(liu)持續(xu)(xu)供(gong)(gong)電(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)源設備。主要用于給單臺計算機、計算機網(wang)絡系統或其它(ta)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)子(zi)設備提供(gong)(gong)不(bu)(bu)間斷(duan)(duan)(duan)的(de)電(dian)(dian)(dian)(dian)力(li)供(gong)(gong)應(ying)(ying)。當(dang)市(shi)電(dian)(dian)(dian)(dian)輸(shu)入正(zheng)(zheng)(zheng)常(chang)(chang)時(shi)(shi)，UPS 將市(shi)電(dian)(dian)(dian)(dian)穩(wen)壓(ya)(ya)后供(gong)(gong)應(ying)(ying)給負載使用，此(ci)時(shi)(shi)的(de)UPS就是一臺交(jiao)(jiao)流(liu)市(shi)電(dian)(dian)(dian)(dian)穩(wen)壓(ya)(ya)器，同時(shi)(shi)它(ta)還向機內電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)；當(dang)市(shi)電(dian)(dian)(dian)(dian)中斷(duan)(duan)(duan)時(shi)(shi)， UPS 立(li)即將機內電(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)能，通過逆變(bian)轉換(huan)的(de)方法(fa)向負載繼續(xu)(xu)供(gong)(gong)應(ying)(ying)220V交(jiao)(jiao)流(liu)電(dian)(dian)(dian)(dian)，使負載維持正(zheng)(zheng)(zheng)常(chang)(chang)工作(zuo)并保護(hu)(hu)負載軟、硬件不(bu)(bu)受損壞。UPS 設備通常(chang)(chang)對電(dian)(dian)(dian)(dian)壓(ya)(ya)過大(da)和電(dian)(dian)(dian)(dian)壓(ya)(ya)太低都(dou)提供(gong)(gong)保護(hu)(hu)。

二、ups不間斷電源能供電多久

UPS不(bu)間斷電源產品可(ke)以使(shi)用的(de)年限是多(duo)久(jiu)，這個根據不(bu)同的(de)ups不間斷電源品牌，質量，售(shou)后服務，維保服務等因數(shu)決定，一般(ban)(ban)使用10年以上都(dou)有，質保期一般(ban)(ban)是3-4年，維保可以購(gou)買年限(xian)。

UPS不間(jian)斷電(dian)源可以(yi)供電(dian)多久(jiu)，這個(ge)又分為外置電(dian)池和(he)內(nei)置電(dian)池，內(nei)置電(dian)池的UPS電(dian)源一般是標(biao)準機，標(biao)準供電(dian)時間(jian)3分鐘(zhong)左右，外置電(dian)池是根據(ju)您的供電(dian)需求，進行(xing)額外增加，可以(yi)配置供電(dian)時間(jian)達到23小時左右。

另外(wai)，UPS不間斷電(dian)源能供電(dian)多(duo)這取決于(yu)運行的環(huan)境(jing)(jing)，維護和保(bao)養的情況(kuang)，公司(si)對舊UPS的態度，如(ru)果低效、容量不夠(gou)，運行環(huan)境(jing)(jing)差，如(ru)溫度過高(gao)、灰層太大、潮濕等等都會(hui)減短UPS的壽(shou)命，維護和保(bao)養不到位，也會(hui)縮短UPS的壽(shou)命。

正常的(de)來(lai)說，UPS電源的(de)使(shi)用(yong)壽命一般都可以達到8-10年(nian)，而維(wei)護得(de)當的(de)UPS電源這可以使(shi)用(yong)15年(nian)以上，像美國很多地方的(de)數據中心(xin)都用(yong)了(le)20年(nian)上下，里面的(de)UPS電源也(ye)從來(lai)沒有更換過。

小(xiao)型(xing)家(jia)用電(dian)腦UPS不(bu)間斷電(dian)源時(shi)間一般能維持20分鐘。大型(xing)千瓦級(ji)別UPS可根據(ju)要(yao)求(qiu)設置電(dian)池組，一般1個(ge)小(xiao)時(shi)以上(shang)到10個(ge)小(xiao)時(shi)。

三、ups不間斷電源維修

其余正(zheng)常，但是(shi)無逆(ni)變跡象，由此(ci)懷(huai)疑是(shi)某IC損壞(huai)，更換即可(ke)。開機不反應(ying)，不工(gong)作，最常見的(de)原因是(shi)機內低壓電(dian)路(lu)的(de)供電(dian)不正(zheng)常，而這種供電(dian)不正(zheng)常一(yi)般是(shi)因機內電(dian)瓶損壞(huai)、低壓保險(xian)絲(si)損壞(huai)引起。電(dian)瓶兩(liang)端僅(jin)有不足5v的(de)電(dian)壓，用新(xin)電(dian)瓶替換，將(jiang)電(dian)源(yuan)插頭插入(ru)市電(dian)，開機后立刻正(zheng)常。說明是(shi)假(jia)性(xing)損壞(huai)，屬于(yu)自然(ran)放電(dian)導(dao)致。
