一、ups不間斷電源的作用

當正常(chang)交(jiao)(jiao)流供(gong)電(dian)(dian)(dian)(dian)(dian)中(zhong)斷時(shi)，將(jiang)(jiang)蓄電(dian)(dian)(dian)(dian)(dian)池(chi)輸出的(de)(de)直流變換成交(jiao)(jiao)流持續供(gong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源設(she)備(bei)。主要用于給(gei)單(dan)臺計(ji)(ji)算(suan)機(ji)、計(ji)(ji)算(suan)機(ji)網絡系統或其它(ta)電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)子設(she)備(bei)提供(gong)不間斷的(de)(de)電(dian)(dian)(dian)(dian)(dian)力供(gong)應。當市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)輸入正常(chang)時(shi)，UPS 將(jiang)(jiang)市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)穩壓(ya)后供(gong)應給(gei)負載(zai)使(shi)用，此時(shi)的(de)(de)UPS就是一臺交(jiao)(jiao)流市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)穩壓(ya)器(qi)，同時(shi)它(ta)還向(xiang)機(ji)內電(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)；當市(shi)(shi)電(dian)(dian)(dian)(dian)(dian)中(zhong)斷時(shi)， UPS 立即將(jiang)(jiang)機(ji)內電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)能，通過逆變轉換的(de)(de)方法(fa)向(xiang)負載(zai)繼(ji)續供(gong)應220V交(jiao)(jiao)流電(dian)(dian)(dian)(dian)(dian)，使(shi)負載(zai)維持正常(chang)工(gong)作并保護(hu)負載(zai)軟、硬件(jian)不受損壞。UPS 設(she)備(bei)通常(chang)對電(dian)(dian)(dian)(dian)(dian)壓(ya)過大(da)和電(dian)(dian)(dian)(dian)(dian)壓(ya)太(tai)低都提供(gong)保護(hu)。

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(de)年限是多久，這個根據不(bu)同的(de)ups不間斷電源品牌，質量，售后服務，維(wei)保服務等因數決(jue)定，一般使用10年(nian)以(yi)上都(dou)有(you)，質保期一般是3-4年(nian)，維(wei)保可(ke)以(yi)購買(mai)年(nian)限。

UPS不間(jian)斷(duan)電(dian)源可(ke)以供(gong)電(dian)多(duo)久(jiu)，這個又分(fen)為外置電(dian)池和內置電(dian)池，內置電(dian)池的UPS電(dian)源一般是標準(zhun)機(ji)，標準(zhun)供(gong)電(dian)時間(jian)3分(fen)鐘左右，外置電(dian)池是根據您的供(gong)電(dian)需求，進(jin)行額(e)外增加，可(ke)以配置供(gong)電(dian)時間(jian)達到23小(xiao)時左右。

另(ling)外，UPS不(bu)間斷電源能(neng)供電多這取決于運行的環境，維(wei)護(hu)和保養(yang)的情況(kuang)，公司對舊UPS的態(tai)度，如果(guo)低效、容量不(bu)夠，運行環境差，如溫度過高(gao)、灰層太(tai)大、潮濕(shi)等等都會減短(duan)UPS的壽(shou)(shou)命(ming)，維(wei)護(hu)和保養(yang)不(bu)到位，也會縮短(duan)UPS的壽(shou)(shou)命(ming)。

正常的來說(shuo)，UPS電源(yuan)的使(shi)用(yong)壽命一(yi)般都可(ke)以達到8-10年(nian)，而維護(hu)得當(dang)的UPS電源(yuan)這可(ke)以使(shi)用(yong)15年(nian)以上，像美(mei)國(guo)很多(duo)地方的數據中心都用(yong)了20年(nian)上下，里面(mian)的UPS電源(yuan)也從來沒有(you)更(geng)換(huan)過。

小(xiao)型家用電(dian)(dian)腦UPS不間(jian)(jian)斷電(dian)(dian)源時(shi)間(jian)(jian)一般能維持20分鐘(zhong)。大型千瓦級(ji)別UPS可根據要求設置電(dian)(dian)池組，一般1個小(xiao)時(shi)以上(shang)到10個小(xiao)時(shi)。

三、ups不間斷電源維修

其(qi)余正(zheng)(zheng)(zheng)常，但是無逆變跡象，由此懷(huai)疑是某IC損(sun)壞(huai)，更換即可(ke)。開(kai)機不(bu)反應，不(bu)工作，最(zui)常見的原因(yin)是機內低壓電(dian)路的供電(dian)不(bu)正(zheng)(zheng)(zheng)常，而這種供電(dian)不(bu)正(zheng)(zheng)(zheng)常一般是因(yin)機內電(dian)瓶損(sun)壞(huai)、低壓保險絲損(sun)壞(huai)引起(qi)。電(dian)瓶兩(liang)端僅有不(bu)足5v的電(dian)壓，用新(xin)電(dian)瓶替(ti)換，將(jiang)電(dian)源插頭(tou)插入市(shi)電(dian)，開(kai)機后(hou)立刻正(zheng)(zheng)(zheng)常。說(shuo)明是假性損(sun)壞(huai)，屬于自然放電(dian)導致。
