EPS應急(ji)電(dian)(dian)源(yuan)(yuan)是根據消防設(she)施、應急(ji)照明(ming)、事故(gu)照明(ming)等(deng)一級負荷(he)供(gong)電(dian)(dian)設(she)備需要而組成的電(dian)(dian)源(yuan)(yuan)設(she)備。產品由互投裝(zhuang)(zhuang)(zhuang)置(zhi)、自(zi)動(dong)充電(dian)(dian)機、逆變器及蓄電(dian)(dian)池組等(deng)組成。在交(jiao)(jiao)流(liu)電(dian)(dian)網(wang)正常(chang)時逆變器不工作，經過互投裝(zhuang)(zhuang)(zhuang)置(zhi)給重要負載供(gong)電(dian)(dian)。當(dang)交(jiao)(jiao)流(liu)電(dian)(dian)網(wang)斷電(dian)(dian)后，互投裝(zhuang)(zhuang)(zhuang)置(zhi)將會(hui)立即(ji)投切至逆變電(dian)(dian)源(yuan)(yuan)供(gong)電(dian)(dian)。當(dang)電(dian)(dian)網(wang)電(dian)(dian)壓(ya)恢復時，互投裝(zhuang)(zhuang)(zhuang)置(zhi)將會(hui)投切至交(jiao)(jiao)流(liu)電(dian)(dian)網(wang)供(gong)電(dian)(dian)。

　　UPS不間斷(duan)電(dian)(dian)(dian)(dian)(dian)源(yuan)是將電(dian)(dian)(dian)(dian)(dian)池(chi)(大多(duo)數免維護鉛蓄電(dian)(dian)(dian)(dian)(dian)池(chi))連接到(dao)主(zhu)機(ji)，并通過主(zhu)機(ji)逆變等模塊電(dian)(dian)(dian)(dian)(dian)路將直流(liu)轉換為(wei)主(zhu)電(dian)(dian)(dian)(dian)(dian)流(liu)的系(xi)統設備(bei)。主(zhu)要用于(yu)為(wei)單(dan)臺計算(suan)機(ji)、計算(suan)機(ji)網(wang)絡系(xi)統或其(qi)他(ta)電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)子設備(bei)(例如電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、壓(ya)力變送器等)提供(gong)(gong)穩定(ding)、不間斷(duan)的電(dian)(dian)(dian)(dian)(dian)力供(gong)(gong)應。當電(dian)(dian)(dian)(dian)(dian)源(yuan)輸入正常時，UPS將電(dian)(dian)(dian)(dian)(dian)源(yuan)供(gong)(gong)應給負載。

　　此時，UPS是交(jiao)(jiao)流(liu)電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)壓(ya)調節(jie)器(qi)，為內部電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)。UPS可在(zai)停(ting)電(dian)(dian)(dian)(dian)時立即啟動(dong)電(dian)(dian)(dian)(dian)池的直(zhi)流(liu)電(dian)(dian)(dian)(dian)源(yuan)，通(tong)過逆(ni)變零切換繼續向(xiang)負(fu)載提供220V交(jiao)(jiao)流(liu)電(dian)(dian)(dian)(dian)，保持(chi)負(fu)載正常(chang)運(yun)行(xing)，并保護軟負(fu)載不受硬件損壞(huai)的影響。UPS設備通(tong)常(chang)可以(yi)在(zai)電(dian)(dian)(dian)(dian)壓(ya)過高(gao)或過低(di)的情(qing)況下進行(xing)保護。

　　那么(me)EPS應急電源與UPS電源有什么(me)與眾(zhong)不同呢?下(xia)面大(da)成(cheng)智慧(hui)小(xiao)編來(lai)給(gei)大(da)家(jia)介紹下(xia)EPS應急電源與UPS電源的(de)區別(bie)。

 　　EPS應急電源與UPS電源區別：

　　1、與應(ying)用(yong)不同(tong)，EPS應(ying)急(ji)電源(yuan)主要用(yong)于(yu)消防行(xing)業電氣設備(bei)，強調持續電源(yuan)功能。UPS不間(jian)斷電源(yuan)通常(chang)用(yong)于(yu)計算機、服務(wu)器(qi)等IT行(xing)業設備(bei)等精密儀器(qi)負載，要求(qiu)高供電質量，強調逆變開關時間(jian)、輸(shu)出(chu)電壓、頻率穩定性、輸(shu)出(chu)波(bo)形(xing)的純粹(cui)性。

　　2、與(yu)EPS應(ying)急電源(yuan)和(he)UPS不間斷電源(yuan)區別結構不同，EPS應(ying)急電源(yuan)逆變器冗馀、輸入機柜和(he)插座均位于EPS內(nei)部，電動(dong)(dong)機負載有變頻啟動(dong)(dong)。外殼(ke)和(he)導線具有阻(zu)燃性(xing)，可與(yu)防火(huo)聯(lian)系，具有多通道互投資功(gong)能(neng)。UPS不間斷電源(yuan)的逆變器冗馀與(yu)火(huo)災無(wu)關，沒有互投資功(gong)能(neng)。

　　EPS應(ying)急(ji)電(dian)源負(fu)載通常是具有電(dian)動(dong)機(ji)、照明、風扇、泵等(deng)設備的官(guan)能、電(dian)阻、應(ying)急(ji)消(xiao)防(fang)產品，是用于中央應(ying)急(ji)電(dian)源的專用應(ying)急(ji)消(xiao)防(fang)照明電(dian)源。UPS不(bu)間(jian)斷電(dian)源負(fu)載屬于電(dian)容式負(fu)載，主皮帶裝置(zhi)通常主要(yao)用于大(da)型機(ji)房，確保不(bu)間(jian)斷電(dian)源和電(dian)壓(ya)調(diao)節器。

　　3、功(gong)(gong)能(neng)(neng)EPS應(ying)急電(dian)源和(he)UPS不間斷電(dian)源均(jun)為城市具(ju)有(you)旁路(lu)和(he)逆變電(dian)路(lu)。功(gong)(gong)能(neng)(neng)上的差異(yi)是(shi)，EPS應(ying)急電(dian)源具(ju)有(you)持續電(dian)源功(gong)(gong)能(neng)(neng)，一般(ban)對(dui)(dui)逆變開(kai)關時(shi)間要求不高，對(dui)(dui)于特定應(ying)用(yong)程序，必須具(ju)有(you)多(duo)輸出、每個(ge)輸出和(he)單個(ge)電(dian)池的監控和(he)檢(jian)測功(gong)(gong)能(neng)(neng)。日(ri)常(chang)注(zhu)重旁路(lu)功(gong)(gong)率，只有(you)當市外電(dian)力中斷時(shi)，才(cai)能(neng)(neng)轉換到(dao)逆變器，電(dian)力利(li)用(yong)率高。

　　UPS電源(yuan)通常(chang)強(qiang)調三(san)個主要功能：(a)電壓調節(jie)；(b)不間(jian)斷電源(yuan)；(c)在(zai)切(qie)換時間(jian)要求極高(gao)的情況下，能夠一(yi)次性完(wan)成(cheng)全部(bu)輸出(例如聯機(ji))，以(yi)及(ji)凈化(hua)主電源(yuan)。以(yi)整流/逆變器為(wei)重(zhong)點(dian)的雙轉換電路(lu)電源(yuan)，發生逆變故障(zhang)或(huo)過載時，轉換為(wei)旁(pang)路(lu)電源(yuan)，因此功率利用(yong)率不高(gao)(一(yi)般為(wei)80%-90%)。但(dan)是(shi)，在(zai)國(guo)外(wai)電力(li)較好的國(guo)家，為(wei)了節(jie)約能源(yuan)，部(bu)分UPS使用(yong)場所(suo)已被逆變開關時間(jian)很(hen)短(小于10毫秒)的EPS所(suo)取代。

　　以上內容就是對(dui)EPS應(ying)急電(dian)源(yuan)(yuan)與UPS電(dian)源(yuan)(yuan)有什么(me)與眾不(bu)(bu)同的介紹了(le)，EPS消防應(ying)急電(dian)源(yuan)(yuan)與UPS不(bu)(bu)間斷(duan)電(dian)源(yuan)(yuan)有著明顯(xian)的區別(bie)，加上EPS應(ying)急電(dian)源(yuan)(yuan)會有幾秒的切換(huan)，而UPS不(bu)(bu)間斷(duan)電(dian)源(yuan)(yuan)則是零(ling)切換(huan)的，因此對(dui)于(yu)使用場所比(bi)較嚴的設備(bei)，必須用UPS而不(bu)(bu)是EPS，比(bi)如醫院ICU重(zhong)癥監(jian)護室設備(bei)，機房服(fu)務器，計算機等設備(bei)或者(zhe)其他需(xu)要(yao)用到UPS不(bu)(bu)間斷(duan)電(dian)源(yuan)(yuan)的場所。因此大家在選擇應(ying)急電(dian)源(yuan)(yuan)時(shi)，針對(dui)所需(xu)環境的要(yao)求給出合理的配(pei)置，使得設備(bei)發揮(hui)更(geng)加的效(xiao)能。
