一、ups不間斷電源的作用
當(dang)正(zheng)常交(jiao)流供(gong)(gong)(gong)電(dian)(dian)中斷(duan)(duan)時(shi)，將蓄電(dian)(dian)池輸出的(de)(de)直(zhi)流變換(huan)成交(jiao)流持續(xu)供(gong)(gong)(gong)電(dian)(dian)的(de)(de)電(dian)(dian)源設(she)備。主要用于給(gei)(gei)單臺計(ji)(ji)算機(ji)、計(ji)(ji)算機(ji)網絡系統或其(qi)它電(dian)(dian)力電(dian)(dian)子設(she)備提供(gong)(gong)(gong)不間斷(duan)(duan)的(de)(de)電(dian)(dian)力供(gong)(gong)(gong)應(ying)(ying)。當(dang)市(shi)電(dian)(dian)輸入正(zheng)常時(shi)，UPS 將市(shi)電(dian)(dian)穩壓后供(gong)(gong)(gong)應(ying)(ying)給(gei)(gei)負(fu)(fu)載(zai)使用，此時(shi)的(de)(de)UPS就是一臺交(jiao)流市(shi)電(dian)(dian)穩壓器，同時(shi)它還向機(ji)內電(dian)(dian)池充(chong)電(dian)(dian)；當(dang)市(shi)電(dian)(dian)中斷(duan)(duan)時(shi)， UPS 立即將機(ji)內電(dian)(dian)池的(de)(de)電(dian)(dian)能，通(tong)過逆變轉換(huan)的(de)(de)方法(fa)向負(fu)(fu)載(zai)繼續(xu)供(gong)(gong)(gong)應(ying)(ying)220V交(jiao)流電(dian)(dian)，使負(fu)(fu)載(zai)維持正(zheng)常工(gong)作并保護負(fu)(fu)載(zai)軟、硬(ying)件不受損壞。UPS 設(she)備通(tong)常對電(dian)(dian)壓過大和電(dian)(dian)壓太(tai)低都提供(gong)(gong)(gong)保護。
二、ups不間斷電源能供電多久
UPS不(bu)間斷電源產品(pin)可以使用的年限是多久，這(zhe)個根據不(bu)同的ups不間斷電源品牌，質量(liang)，售后服務(wu)，維(wei)保服務(wu)等因數決(jue)定，一般(ban)使用10年以上都有，質保期(qi)一般(ban)是(shi)3-4年，維(wei)保可(ke)以購買年限。
UPS不(bu)間斷(duan)電(dian)(dian)(dian)源可以供電(dian)(dian)(dian)多久，這個又分為(wei)外置(zhi)電(dian)(dian)(dian)池和內置(zhi)電(dian)(dian)(dian)池，內置(zhi)電(dian)(dian)(dian)池的(de)UPS電(dian)(dian)(dian)源一般(ban)是標準(zhun)機，標準(zhun)供電(dian)(dian)(dian)時間3分鐘左(zuo)右，外置(zhi)電(dian)(dian)(dian)池是根據(ju)您的(de)供電(dian)(dian)(dian)需求(qiu)，進(jin)行額外增(zeng)加(jia)，可以配置(zhi)供電(dian)(dian)(dian)時間達到23小時左(zuo)右。
另外(wai)，UPS不(bu)間斷電源能供電多(duo)這(zhe)取(qu)決(jue)于運行的環境，維護(hu)(hu)和(he)(he)保養的情(qing)況，公司對舊UPS的態(tai)度(du)，如(ru)果低效(xiao)、容量不(bu)夠，運行環境差，如(ru)溫度(du)過高、灰(hui)層太大(da)、潮濕等(deng)等(deng)都(dou)會(hui)減短UPS的壽命，維護(hu)(hu)和(he)(he)保養不(bu)到位，也會(hui)縮短UPS的壽命。
正常的(de)(de)來說，UPS電(dian)(dian)源的(de)(de)使用(yong)壽命一般都(dou)可以達到8-10年，而維護得當的(de)(de)UPS電(dian)(dian)源這可以使用(yong)15年以上，像美國很(hen)多(duo)地方的(de)(de)數據中心(xin)都(dou)用(yong)了20年上下，里面(mian)的(de)(de)UPS電(dian)(dian)源也從來沒有更換(huan)過。
小(xiao)(xiao)型家用電腦UPS不(bu)間斷電源(yuan)時(shi)間一(yi)般能維(wei)持(chi)20分(fen)鐘(zhong)。大型千瓦級別UPS可根據要求設置電池組，一(yi)般1個小(xiao)(xiao)時(shi)以上到10個小(xiao)(xiao)時(shi)。
三、ups不間斷電源維修
其余正(zheng)常(chang)(chang)，但是(shi)無(wu)逆變(bian)跡象，由此懷疑是(shi)某IC損(sun)壞，更(geng)換即(ji)可。開機(ji)不(bu)反(fan)應，不(bu)工作，最常(chang)(chang)見(jian)的原因是(shi)機(ji)內(nei)低壓電(dian)(dian)路的供電(dian)(dian)不(bu)正(zheng)常(chang)(chang)，而這種供電(dian)(dian)不(bu)正(zheng)常(chang)(chang)一般是(shi)因機(ji)內(nei)電(dian)(dian)瓶(ping)損(sun)壞、低壓保險絲損(sun)壞引起。電(dian)(dian)瓶(ping)兩端僅有不(bu)足5v的電(dian)(dian)壓，用新(xin)電(dian)(dian)瓶(ping)替(ti)換，將電(dian)(dian)源(yuan)插頭插入(ru)市電(dian)(dian)，開機(ji)后立刻(ke)正(zheng)常(chang)(chang)。說明是(shi)假性(xing)損(sun)壞，屬于(yu)自然放電(dian)(dian)導致。
