一、ups不間斷電源的作用
當(dang)正常(chang)交流(liu)供(gong)電(dian)(dian)中(zhong)斷時,將(jiang)蓄(xu)電(dian)(dian)池(chi)輸出的直流(liu)變(bian)換成交流(liu)持續(xu)供(gong)電(dian)(dian)的電(dian)(dian)源設(she)備。主(zhu)要用(yong)于給(gei)單臺計算(suan)機(ji)(ji)(ji)、計算(suan)機(ji)(ji)(ji)網絡系統或其(qi)它(ta)(ta)電(dian)(dian)力電(dian)(dian)子設(she)備提(ti)供(gong)不間斷的電(dian)(dian)力供(gong)應(ying)(ying)。當(dang)市電(dian)(dian)輸入正常(chang)時,UPS 將(jiang)市電(dian)(dian)穩(wen)壓(ya)(ya)后供(gong)應(ying)(ying)給(gei)負(fu)載(zai)使(shi)(shi)用(yong),此時的UPS就是(shi)一臺交流(liu)市電(dian)(dian)穩(wen)壓(ya)(ya)器,同時它(ta)(ta)還向(xiang)機(ji)(ji)(ji)內(nei)(nei)電(dian)(dian)池(chi)充電(dian)(dian);當(dang)市電(dian)(dian)中(zhong)斷時, UPS 立即將(jiang)機(ji)(ji)(ji)內(nei)(nei)電(dian)(dian)池(chi)的電(dian)(dian)能,通(tong)過逆變(bian)轉換的方法向(xiang)負(fu)載(zai)繼續(xu)供(gong)應(ying)(ying)220V交流(liu)電(dian)(dian),使(shi)(shi)負(fu)載(zai)維(wei)持正常(chang)工作并保(bao)護負(fu)載(zai)軟、硬件不受損壞。UPS 設(she)備通(tong)常(chang)對電(dian)(dian)壓(ya)(ya)過大和電(dian)(dian)壓(ya)(ya)太低都提(ti)供(gong)保(bao)護。
二、ups不間斷電源能供電多久
UPS不間斷(duan)電源(yuan)產(chan)品(pin)可以(yi)使用的年限是多久(jiu),這(zhe)個(ge)根據(ju)不同的ups不間斷電源品牌,質(zhi)量,售后服(fu)務,維保服(fu)務等因(yin)數決定,一(yi)般(ban)使(shi)用10年以上都有,質(zhi)保期一(yi)般(ban)是(shi)3-4年,維保可以購買年限(xian)。
UPS不(bu)間斷電(dian)(dian)源(yuan)(yuan)可以供(gong)電(dian)(dian)多(duo)久,這(zhe)個(ge)又分(fen)為外(wai)置(zhi)電(dian)(dian)池和內置(zhi)電(dian)(dian)池,內置(zhi)電(dian)(dian)池的UPS電(dian)(dian)源(yuan)(yuan)一(yi)般是標準機,標準供(gong)電(dian)(dian)時(shi)間3分(fen)鐘左(zuo)右(you),外(wai)置(zhi)電(dian)(dian)池是根據您的供(gong)電(dian)(dian)需求,進行(xing)額外(wai)增加,可以配置(zhi)供(gong)電(dian)(dian)時(shi)間達到23小時(shi)左(zuo)右(you)。
另外(wai),UPS不(bu)間斷電源能供(gong)電多這取決于運行的(de)(de)環境,維(wei)護和保養的(de)(de)情況(kuang),公(gong)司對舊UPS的(de)(de)態度(du),如果低效、容量不(bu)夠,運行環境差,如溫度(du)過高、灰層太大、潮濕(shi)等等都會減短UPS的(de)(de)壽命,維(wei)護和保養不(bu)到(dao)位,也會縮(suo)短UPS的(de)(de)壽命。
正常的(de)(de)來(lai)說(shuo),UPS電(dian)源的(de)(de)使(shi)用(yong)壽命一般都(dou)可以達到8-10年(nian),而(er)維(wei)護得當的(de)(de)UPS電(dian)源這(zhe)可以使(shi)用(yong)15年(nian)以上,像美國(guo)很(hen)多地方的(de)(de)數據中(zhong)心(xin)都(dou)用(yong)了20年(nian)上下,里面的(de)(de)UPS電(dian)源也從來(lai)沒有更換過。
小(xiao)型家用(yong)電腦(nao)UPS不間(jian)(jian)斷電源時(shi)間(jian)(jian)一(yi)般(ban)能維(wei)持(chi)20分鐘。大型千瓦(wa)級別(bie)UPS可根據(ju)要求設置電池組,一(yi)般(ban)1個(ge)小(xiao)時(shi)以上到10個(ge)小(xiao)時(shi)。
三、ups不間斷電源維修
其余正常(chang),但是(shi)無逆變(bian)跡象,由此懷疑(yi)是(shi)某IC損(sun)(sun)壞,更換即可。開(kai)機(ji)不(bu)(bu)反(fan)應,不(bu)(bu)工作(zuo),最(zui)常(chang)見的原因是(shi)機(ji)內低(di)壓(ya)(ya)電(dian)(dian)路的供(gong)電(dian)(dian)不(bu)(bu)正常(chang),而這種供(gong)電(dian)(dian)不(bu)(bu)正常(chang)一般是(shi)因機(ji)內電(dian)(dian)瓶(ping)損(sun)(sun)壞、低(di)壓(ya)(ya)保險絲損(sun)(sun)壞引起(qi)。電(dian)(dian)瓶(ping)兩(liang)端僅(jin)有不(bu)(bu)足5v的電(dian)(dian)壓(ya)(ya),用新電(dian)(dian)瓶(ping)替換,將電(dian)(dian)源插頭插入(ru)市電(dian)(dian),開(kai)機(ji)后立刻正常(chang)。說明是(shi)假性損(sun)(sun)壞,屬于自然放電(dian)(dian)導致。
