眾(zhong)所(suo)周知(zhi)，EPS消(xiao)防(fang)應(ying)急(ji)電(dian)源(yuan)(yuan)與UPS不(bu)間(jian)斷(duan)電(dian)源(yuan)(yuan)都是備(bei)用(yong)(yong)電(dian)源(yuan)(yuan)設備(bei)，都是在(zai)市(shi)電(dian)斷(duan)電(dian)情況下給負載(zai)提供備(bei)用(yong)(yong)電(dian)源(yuan)(yuan)的應(ying)急(ji)電(dian)源(yuan)(yuan)設備(bei)，雖然這兩(liang)種電(dian)源(yuan)(yuan)設備(bei)作用(yong)(yong)差不(bu)多，但是由于(yu)使用(yong)(yong)環境不(bu)同，需要用(yong)(yong)的應(ying)急(ji)電(dian)源(yuan)(yuan)類型也不(bu)一(yi)樣。EPS消(xiao)防(fang)應(ying)急(ji)電(dian)源(yuan)(yuan)和(he)UPS不(bu)間(jian)斷(duan)電(dian)源(yuan)(yuan)的區別(bie)，主要體現在(zai)工作方式、應(ying)用(yong)(yong)場合，部(bu)件構造，負載(zai)類型，選型配置、元器件選用(yong)(yong)要求、消(xiao)防(fang)特性、安全性能和(he)消(xiao)防(fang)驗收(shou)等(deng)方面，今天(tian)本(ben)文針對(dui)UPS電(dian)源(yuan)(yuan)和(he)EPS電(dian)源(yuan)(yuan)的區別(bie)做(zuo)出具體分(fen)析，希(xi)望(wang)能讓大家(jia)對(dui)此有所(suo)了解。

UPS電源和EPS電源的區別

一、功能上的區別

這兩者均有(you)市電(dian)(dian)(dian)旁(pang)路(lu)(lu)(lu)(lu)及逆變(bian)(bian)(bian)電(dian)(dian)(dian)路(lu)(lu)(lu)(lu)，但(dan)EPS僅具有(you)持續供(gong)電(dian)(dian)(dian)功能(neng)(neng)(neng)，一(yi)般對逆變(bian)(bian)(bian)切(qie)換(huan)時間(jian)要求不高(gao)(gao)，可(ke)有(you)多路(lu)(lu)(lu)(lu)輸(shu)(shu)出(chu)，有(you)些(xie)EPS還配置(zhi)蓄電(dian)(dian)(dian)池單體(ti)監(jian)測功能(neng)(neng)(neng)。EPS在市電(dian)(dian)(dian)正(zheng)常(chang)時由旁(pang)路(lu)(lu)(lu)(lu)供(gong)電(dian)(dian)(dian)。在市電(dian)(dian)(dian)中斷時才轉為逆變(bian)(bian)(bian)供(gong)電(dian)(dian)(dian)，電(dian)(dian)(dian)能(neng)(neng)(neng)利(li)用(yong)率(lv)高(gao)(gao)，而UPS一(yi)般強調其(qi)三大功能(neng)(neng)(neng)：穩壓(ya)穩頻；對切(qie)換(huan)時間(jian)要求極高(gao)(gao)的不問斷供(gong)電(dian)(dian)(dian)；凈化市電(dian)(dian)(dian)；在日常(chang)著(zhu)重整流，逆變(bian)(bian)(bian)的雙(shuang)變(bian)(bian)(bian)換(huan)電(dian)(dian)(dian)路(lu)(lu)(lu)(lu)供(gong)電(dian)(dian)(dian)，在逆變(bian)(bian)(bian)器故障或過載時才轉為旁(pang)路(lu)(lu)(lu)(lu)供(gong)電(dian)(dian)(dian)，電(dian)(dian)(dian)能(neng)(neng)(neng)利(li)用(yong)率(lv)不高(gao)(gao)。UPS并不是(shi)僅在市電(dian)(dian)(dian)中斷時才發揮作用(yong)。當市電(dian)(dian)(dian)出(chu)現電(dian)(dian)(dian)壓(ya)過低、過高(gao)(gao)，線路(lu)(lu)(lu)(lu)出(chu)現浪涌等異常(chang)情況，UPS能(neng)(neng)(neng)輸(shu)(shu)出(chu)高(gao)(gao)質量(liang)電(dian)(dian)(dian)源，確保用(yong)電(dian)(dian)(dian)設備正(zheng)常(chang)運行；

二、輸出上的區別

UPS的供電(dian)(dian)對(dui)象是(shi)(shi)計算(suan)機及網絡設備。負(fu)載(zai)性(xing)(xing)質差(cha)別不大(da)，所(suo)以(yi)(yi)(yi)國(guo)標規定UPS輸出功(gong)率因數為(wei)(wei)0.8。而(er)EPS主要(yao)(yao)(yao)(yao)是(shi)(shi)作為(wei)(wei)電(dian)(dian)源(yuan)應急(ji)保(bao)障，負(fu)載(zai)性(xing)(xing)質為(wei)(wei)感性(xing)(xing)、容(rong)性(xing)(xing)及整流(liu)性(xing)(xing)負(fu)載(zai)兼(jian)而(er)有之。有些負(fu)載(zai)是(shi)(shi)市電(dian)(dian)停電(dian)(dian)后才投入工作的。因而(er)要(yao)(yao)(yao)(yao)求(qiu)EPS能提(ti)供很大(da)的沖(chong)擊電(dian)(dian)流(liu)，一般(ban)要(yao)(yao)(yao)(yao)求(qiu)120%額定負(fu)載(zai)下(xia)仍能正常運行10rain以(yi)(yi)(yi)上，所(suo)以(yi)(yi)(yi)EPS需要(yao)(yao)(yao)(yao)輸出動態特性(xing)(xing)要(yao)(yao)(yao)(yao)好，抗過(guo)載(zai)能力要(yao)(yao)(yao)(yao)強。UPS額定容(rong)量以(yi)(yi)(yi)視在(zai)功(gong)率（kv·A）為(wei)(wei)單位，EPS額定容(rong)量以(yi)(yi)(yi)有功(gong)功(gong)率（kW）為(wei)(wei)單位。在(zai)線式UPS為(wei)(wei)保(bao)證(zheng)輸出供電(dian)(dian)不間斷和優(you)質供電(dian)(dian)，選擇逆變優(you)先(xian)。而(er)EPS電(dian)(dian)源(yuan)為(wei)(wei)保(bao)證(zheng)應急(ji)使用，是(shi)(shi)選擇市電(dian)(dian)優(you)先(xian)；

三、安全性能上的區別

EPS消防(fang)應急(ji)電(dian)(dian)源由于對消防(fang)設備特殊(shu)的人(ren)(ren)身(shen)安(an)全要(yao)求，EPS應急(ji)電(dian)(dian)源需配(pei)有隔離變壓(ya)器，以保證人(ren)(ren)身(shen)安(an)全；UPS不間斷電(dian)(dian)源沒有配(pei)置隔離變壓(ya)器，如用于消防(fang)設備供電(dian)(dian)，存在(zai)觸電(dian)(dian)隱患。

四、應用領域上的區別

在(zai)我國EPS主要(yao)用于(yu)消防(fang)類負(fu)荷及一些對(dui)供(gong)電(dian)(dian)質量要(yao)求不太高(gao)，但需保證連續供(gong)電(dian)(dian)的(de)用電(dian)(dian)設備。僅強調能(neng)持續供(gong)電(dian)(dian)這一功能(neng)。EPS用于(yu)消防(fang)負(fu)荷時，其產品技(ji)術受(shou)公安部(bu)消防(fang)認證。UPS一般用于(yu)計算機及數字(zi)信息系統等(deng)場(chang)合。要(yao)求供(gong)電(dian)(dian)質量較(jiao)高(gao)的(de)負(fu)載(zai)，主要(yao)強調逆變切(qie)換時間、輸出電(dian)(dian)壓、頻率穩定性、輸出波形的(de)純正(zheng)、無各(ge)種干擾等(deng)。
