一、ups不間斷電源的作用

當(dang)正(zheng)常交流(liu)供(gong)(gong)電(dian)(dian)(dian)(dian)中(zhong)斷時(shi)，將蓄(xu)電(dian)(dian)(dian)(dian)池輸出的直流(liu)變換(huan)成(cheng)交流(liu)持續供(gong)(gong)電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)源設備(bei)(bei)。主要用于給單(dan)臺計(ji)算機(ji)(ji)、計(ji)算機(ji)(ji)網絡系統或其它(ta)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)子設備(bei)(bei)提(ti)供(gong)(gong)不間斷的電(dian)(dian)(dian)(dian)力供(gong)(gong)應。當(dang)市電(dian)(dian)(dian)(dian)輸入正(zheng)常時(shi)，UPS 將市電(dian)(dian)(dian)(dian)穩壓(ya)(ya)(ya)后供(gong)(gong)應給負(fu)(fu)載(zai)使用，此時(shi)的UPS就是一臺交流(liu)市電(dian)(dian)(dian)(dian)穩壓(ya)(ya)(ya)器，同時(shi)它(ta)還向機(ji)(ji)內(nei)電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)；當(dang)市電(dian)(dian)(dian)(dian)中(zhong)斷時(shi)， UPS 立即將機(ji)(ji)內(nei)電(dian)(dian)(dian)(dian)池的電(dian)(dian)(dian)(dian)能，通過逆(ni)變轉換(huan)的方法向負(fu)(fu)載(zai)繼續供(gong)(gong)應220V交流(liu)電(dian)(dian)(dian)(dian)，使負(fu)(fu)載(zai)維(wei)持正(zheng)常工作(zuo)并保(bao)護負(fu)(fu)載(zai)軟(ruan)、硬件不受損壞。UPS 設備(bei)(bei)通常對電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)過大和電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)太低(di)都提(ti)供(gong)(gong)保(bao)護。

二、ups不間斷電源能供電多久

UPS不間斷電源產品可以使(shi)用的年(nian)限是多久，這個根據不同的ups不間斷電源品牌，質(zhi)量(liang)，售(shou)后(hou)服務，維保(bao)服務等(deng)因數決定，一般使(shi)用(yong)10年以(yi)(yi)上都有，質(zhi)保(bao)期(qi)一般是(shi)3-4年，維保(bao)可以(yi)(yi)購買年限。

UPS不(bu)間斷(duan)電源(yuan)可以供(gong)電多久，這(zhe)個又分為外(wai)(wai)置(zhi)(zhi)電池(chi)和內置(zhi)(zhi)電池(chi)，內置(zhi)(zhi)電池(chi)的UPS電源(yuan)一般是標準(zhun)機，標準(zhun)供(gong)電時間3分鐘左右，外(wai)(wai)置(zhi)(zhi)電池(chi)是根據(ju)您的供(gong)電需求，進行額(e)外(wai)(wai)增加，可以配置(zhi)(zhi)供(gong)電時間達到(dao)23小時左右。

另外，UPS不間斷電源(yuan)能(neng)供(gong)電多這取決于運(yun)(yun)行的環境(jing)，維(wei)護和保(bao)養(yang)的情(qing)況，公(gong)司對(dui)舊UPS的態度，如果(guo)低效、容量不夠，運(yun)(yun)行環境(jing)差，如溫度過(guo)高、灰層太(tai)大、潮濕等(deng)等(deng)都會減短UPS的壽命(ming)，維(wei)護和保(bao)養(yang)不到位，也會縮短UPS的壽命(ming)。

正常的來(lai)說，UPS電源的使用(yong)壽命一般都可以(yi)達到8-10年，而維護得當的UPS電源這(zhe)可以(yi)使用(yong)15年以(yi)上，像美國很多(duo)地方(fang)的數據中心都用(yong)了20年上下，里面的UPS電源也從來(lai)沒有更換過。

小(xiao)型(xing)家(jia)用電腦UPS不間斷電源時(shi)間一(yi)般(ban)能維持20分鐘。大型(xing)千瓦級別UPS可根據要求設(she)置電池組，一(yi)般(ban)1個小(xiao)時(shi)以上到10個小(xiao)時(shi)。

三、ups不間斷電源維修

其余正(zheng)常(chang)(chang)(chang)，但是(shi)無逆變跡象，由此(ci)懷疑是(shi)某IC損(sun)(sun)壞，更換即可。開機不(bu)反(fan)應，不(bu)工作，最(zui)常(chang)(chang)(chang)見的原因(yin)是(shi)機內低壓電(dian)路的供(gong)電(dian)不(bu)正(zheng)常(chang)(chang)(chang)，而這種供(gong)電(dian)不(bu)正(zheng)常(chang)(chang)(chang)一般是(shi)因(yin)機內電(dian)瓶損(sun)(sun)壞、低壓保險(xian)絲損(sun)(sun)壞引起。電(dian)瓶兩端僅有不(bu)足5v的電(dian)壓，用新(xin)電(dian)瓶替換，將電(dian)源插頭插入(ru)市電(dian)，開機后立刻正(zheng)常(chang)(chang)(chang)。說明是(shi)假性損(sun)(sun)壞，屬(shu)于自然(ran)放電(dian)導(dao)致。
