眾所周知，EPS消防(fang)應(ying)(ying)急電(dian)(dian)(dian)(dian)源(yuan)(yuan)與UPS不間(jian)斷(duan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)都(dou)(dou)是(shi)備用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)設(she)備，都(dou)(dou)是(shi)在(zai)市電(dian)(dian)(dian)(dian)斷(duan)電(dian)(dian)(dian)(dian)情(qing)況下給負載提供(gong)備用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)應(ying)(ying)急電(dian)(dian)(dian)(dian)源(yuan)(yuan)設(she)備，雖然(ran)這(zhe)兩(liang)種(zhong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)設(she)備作用(yong)(yong)(yong)差不多，但(dan)是(shi)由于使用(yong)(yong)(yong)環境不同，需要用(yong)(yong)(yong)的(de)應(ying)(ying)急電(dian)(dian)(dian)(dian)源(yuan)(yuan)類型(xing)也(ye)不一(yi)樣。EPS消防(fang)應(ying)(ying)急電(dian)(dian)(dian)(dian)源(yuan)(yuan)和(he)UPS不間(jian)斷(duan)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)區別(bie)，主要體(ti)現在(zai)工(gong)作方式、應(ying)(ying)用(yong)(yong)(yong)場合，部(bu)件構(gou)造，負載類型(xing)，選型(xing)配置(zhi)、元器件選用(yong)(yong)(yong)要求(qiu)、消防(fang)特(te)性、安(an)全性能和(he)消防(fang)驗(yan)收等方面，今天本文針對UPS電(dian)(dian)(dian)(dian)源(yuan)(yuan)和(he)EPS電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)區別(bie)做出(chu)具體(ti)分析，希望能讓大家對此有(you)所了解。

UPS電源和EPS電源的區別

一、功能上的區別

這兩(liang)者均有(you)市(shi)電(dian)(dian)(dian)旁(pang)路(lu)(lu)及逆(ni)變(bian)(bian)電(dian)(dian)(dian)路(lu)(lu)，但EPS僅具有(you)持(chi)續供(gong)電(dian)(dian)(dian)功(gong)能，一般(ban)對逆(ni)變(bian)(bian)切(qie)換(huan)時(shi)(shi)間要(yao)求不(bu)高(gao)(gao)，可有(you)多路(lu)(lu)輸(shu)出(chu)(chu)，有(you)些(xie)EPS還配(pei)置蓄電(dian)(dian)(dian)池單體監測功(gong)能。EPS在(zai)(zai)市(shi)電(dian)(dian)(dian)正常(chang)時(shi)(shi)由(you)旁(pang)路(lu)(lu)供(gong)電(dian)(dian)(dian)。在(zai)(zai)市(shi)電(dian)(dian)(dian)中(zhong)斷時(shi)(shi)才(cai)轉(zhuan)為逆(ni)變(bian)(bian)供(gong)電(dian)(dian)(dian)，電(dian)(dian)(dian)能利用(yong)率高(gao)(gao)，而UPS一般(ban)強調(diao)其三(san)大(da)功(gong)能：穩壓(ya)穩頻；對切(qie)換(huan)時(shi)(shi)間要(yao)求極高(gao)(gao)的不(bu)問斷供(gong)電(dian)(dian)(dian)；凈化(hua)市(shi)電(dian)(dian)(dian)；在(zai)(zai)日常(chang)著重整流(liu)，逆(ni)變(bian)(bian)的雙變(bian)(bian)換(huan)電(dian)(dian)(dian)路(lu)(lu)供(gong)電(dian)(dian)(dian)，在(zai)(zai)逆(ni)變(bian)(bian)器故障或過載時(shi)(shi)才(cai)轉(zhuan)為旁(pang)路(lu)(lu)供(gong)電(dian)(dian)(dian)，電(dian)(dian)(dian)能利用(yong)率不(bu)高(gao)(gao)。UPS并不(bu)是僅在(zai)(zai)市(shi)電(dian)(dian)(dian)中(zhong)斷時(shi)(shi)才(cai)發揮(hui)作用(yong)。當(dang)市(shi)電(dian)(dian)(dian)出(chu)(chu)現電(dian)(dian)(dian)壓(ya)過低、過高(gao)(gao)，線(xian)路(lu)(lu)出(chu)(chu)現浪(lang)涌等異常(chang)情(qing)況，UPS能輸(shu)出(chu)(chu)高(gao)(gao)質量電(dian)(dian)(dian)源(yuan)，確保用(yong)電(dian)(dian)(dian)設(she)備正常(chang)運(yun)行(xing)；

二、輸出上的區別

UPS的(de)供電(dian)對象是計算(suan)機及網絡設備。負(fu)載(zai)(zai)(zai)性(xing)質(zhi)差別不(bu)大(da)，所以(yi)國(guo)標(biao)規定(ding)UPS輸出(chu)功(gong)(gong)率(lv)因(yin)數為(wei)0.8。而(er)(er)EPS主要是作為(wei)電(dian)源應急保障，負(fu)載(zai)(zai)(zai)性(xing)質(zhi)為(wei)感(gan)性(xing)、容性(xing)及整(zheng)流性(xing)負(fu)載(zai)(zai)(zai)兼而(er)(er)有之。有些負(fu)載(zai)(zai)(zai)是市電(dian)停(ting)電(dian)后才投入工作的(de)。因(yin)而(er)(er)要求(qiu)EPS能提供很大(da)的(de)沖擊電(dian)流，一般要求(qiu)120%額(e)(e)定(ding)負(fu)載(zai)(zai)(zai)下仍能正(zheng)常運行(xing)10rain以(yi)上(shang)，所以(yi)EPS需要輸出(chu)動態特性(xing)要好，抗過載(zai)(zai)(zai)能力要強。UPS額(e)(e)定(ding)容量以(yi)視在功(gong)(gong)率(lv)（kv·A）為(wei)單位(wei)，EPS額(e)(e)定(ding)容量以(yi)有功(gong)(gong)功(gong)(gong)率(lv)（kW）為(wei)單位(wei)。在線式UPS為(wei)保證(zheng)輸出(chu)供電(dian)不(bu)間斷和優質(zhi)供電(dian)，選(xuan)擇逆變(bian)優先。而(er)(er)EPS電(dian)源為(wei)保證(zheng)應急使用，是選(xuan)擇市電(dian)優先；

三、安全性能上的區別

EPS消(xiao)防(fang)應(ying)急(ji)電(dian)源(yuan)由于對消(xiao)防(fang)設(she)備特殊(shu)的人身安全(quan)要求，EPS應(ying)急(ji)電(dian)源(yuan)需配有隔離變壓器，以(yi)保證人身安全(quan)；UPS不間斷電(dian)源(yuan)沒有配置隔離變壓器，如用于消(xiao)防(fang)設(she)備供電(dian)，存在觸電(dian)隱患。

四、應用領域上的區別

在我國EPS主要(yao)用(yong)于消(xiao)防(fang)類負荷及一(yi)(yi)些(xie)對供(gong)電質量要(yao)求不太高，但需(xu)保證(zheng)連(lian)續供(gong)電的用(yong)電設備。僅強(qiang)調(diao)能持續供(gong)電這一(yi)(yi)功能。EPS用(yong)于消(xiao)防(fang)負荷時，其產品技術受公安部消(xiao)防(fang)認證(zheng)。UPS一(yi)(yi)般用(yong)于計(ji)算機及數字(zi)信息系統等場合。要(yao)求供(gong)電質量較高的負載，主要(yao)強(qiang)調(diao)逆變切換時間、輸出電壓(ya)、頻率穩(wen)定性、輸出波形的純正(zheng)、無(wu)各種(zhong)干(gan)擾等。
