UPS電源和EPS電源的區別

一、功能上的區別

這(zhe)兩者均有市(shi)電(dian)(dian)(dian)旁路(lu)及逆(ni)(ni)變(bian)電(dian)(dian)(dian)路(lu)，但EPS僅具有持續供(gong)(gong)電(dian)(dian)(dian)功能(neng)，一般(ban)(ban)對(dui)逆(ni)(ni)變(bian)切(qie)換時間要求(qiu)不高(gao)(gao)，可有多路(lu)輸出(chu)，有些EPS還配(pei)置蓄電(dian)(dian)(dian)池單體監測功能(neng)。EPS在(zai)(zai)(zai)市(shi)電(dian)(dian)(dian)正(zheng)(zheng)常(chang)(chang)時由(you)旁路(lu)供(gong)(gong)電(dian)(dian)(dian)。在(zai)(zai)(zai)市(shi)電(dian)(dian)(dian)中斷(duan)時才轉為(wei)逆(ni)(ni)變(bian)供(gong)(gong)電(dian)(dian)(dian)，電(dian)(dian)(dian)能(neng)利用率(lv)高(gao)(gao)，而UPS一般(ban)(ban)強調其三大功能(neng)：穩壓穩頻；對(dui)切(qie)換時間要求(qiu)極(ji)高(gao)(gao)的不問斷(duan)供(gong)(gong)電(dian)(dian)(dian)；凈化市(shi)電(dian)(dian)(dian)；在(zai)(zai)(zai)日常(chang)(chang)著重整流，逆(ni)(ni)變(bian)的雙變(bian)換電(dian)(dian)(dian)路(lu)供(gong)(gong)電(dian)(dian)(dian)，在(zai)(zai)(zai)逆(ni)(ni)變(bian)器故障或過載時才轉為(wei)旁路(lu)供(gong)(gong)電(dian)(dian)(dian)，電(dian)(dian)(dian)能(neng)利用率(lv)不高(gao)(gao)。UPS并不是僅在(zai)(zai)(zai)市(shi)電(dian)(dian)(dian)中斷(duan)時才發揮(hui)作用。當市(shi)電(dian)(dian)(dian)出(chu)現電(dian)(dian)(dian)壓過低(di)、過高(gao)(gao)，線路(lu)出(chu)現浪涌等異常(chang)(chang)情況，UPS能(neng)輸出(chu)高(gao)(gao)質量電(dian)(dian)(dian)源，確保用電(dian)(dian)(dian)設(she)備正(zheng)(zheng)常(chang)(chang)運行；

二、輸出上的區別

UPS的(de)供(gong)電(dian)(dian)對象是(shi)計算機及網絡設備(bei)。負載(zai)性(xing)質(zhi)差(cha)別不大(da)，所以(yi)國標規定(ding)UPS輸(shu)出(chu)功(gong)率因數為(wei)(wei)0.8。而(er)EPS主要(yao)是(shi)作(zuo)為(wei)(wei)電(dian)(dian)源(yuan)應急保(bao)(bao)障(zhang)，負載(zai)性(xing)質(zhi)為(wei)(wei)感性(xing)、容性(xing)及整流(liu)性(xing)負載(zai)兼而(er)有之。有些負載(zai)是(shi)市(shi)電(dian)(dian)停電(dian)(dian)后(hou)才(cai)投入工作(zuo)的(de)。因而(er)要(yao)求(qiu)EPS能(neng)提供(gong)很大(da)的(de)沖(chong)擊(ji)電(dian)(dian)流(liu)，一般要(yao)求(qiu)120%額定(ding)負載(zai)下仍能(neng)正(zheng)常運行(xing)10rain以(yi)上(shang)，所以(yi)EPS需(xu)要(yao)輸(shu)出(chu)動態特性(xing)要(yao)好，抗(kang)過載(zai)能(neng)力要(yao)強。UPS額定(ding)容量以(yi)視在功(gong)率（kv·A）為(wei)(wei)單(dan)位，EPS額定(ding)容量以(yi)有功(gong)功(gong)率（kW）為(wei)(wei)單(dan)位。在線式UPS為(wei)(wei)保(bao)(bao)證(zheng)輸(shu)出(chu)供(gong)電(dian)(dian)不間斷(duan)和優(you)質(zhi)供(gong)電(dian)(dian)，選擇逆(ni)變(bian)優(you)先。而(er)EPS電(dian)(dian)源(yuan)為(wei)(wei)保(bao)(bao)證(zheng)應急使(shi)用，是(shi)選擇市(shi)電(dian)(dian)優(you)先；

三、安全性能上的區別

EPS消防應(ying)急電源由于對消防設備特殊(shu)的人身安(an)全(quan)要求，EPS應(ying)急電源需(xu)配有隔離變(bian)壓(ya)器(qi)，以保證人身安(an)全(quan)；UPS不間斷電源沒有配置隔離變(bian)壓(ya)器(qi)，如用于消防設備供(gong)電，存(cun)在觸電隱患。

四、應用領域上的區別

在我國EPS主(zhu)要用(yong)于(yu)消防類負(fu)荷及一(yi)些對供電(dian)(dian)(dian)質(zhi)量(liang)要求不(bu)太高(gao)，但需保證(zheng)連(lian)續(xu)供電(dian)(dian)(dian)的(de)(de)用(yong)電(dian)(dian)(dian)設備。僅(jin)強調能(neng)持續(xu)供電(dian)(dian)(dian)這(zhe)一(yi)功能(neng)。EPS用(yong)于(yu)消防負(fu)荷時，其產品技術受公安部消防認證(zheng)。UPS一(yi)般用(yong)于(yu)計(ji)算機及數(shu)字信息系(xi)統等場合。要求供電(dian)(dian)(dian)質(zhi)量(liang)較高(gao)的(de)(de)負(fu)載，主(zhu)要強調逆變切換時間(jian)、輸出電(dian)(dian)(dian)壓、頻率穩(wen)定性、輸出波形的(de)(de)純正(zheng)、無(wu)各種(zhong)干擾等。
