EPS電源是什么意思?

　　EPS電(dian)源是，當今重要建筑物中為了電(dian)(dian)(dian)力(li)保障和消(xiao)防安全，而采用的一種應(ying)急電(dian)(dian)(dian)源(yuan)。它主要由輸入輸出單元、充(chong)電(dian)(dian)(dian)模塊、電(dian)(dian)(dian)池組、逆變器(qi)、監控器(qi)、輸出切換裝置等(deng)部分組成。廣泛應(ying)用于節(jie)能(neng)供電(dian)(dian)(dian)、大樓照明、道(dao)路交(jiao)通照明、隧(sui)道(dao)照明、電(dian)(dian)(dian)力(li)、工礦企業、消(xiao)防電(dian)(dian)(dian)梯等(deng)。

　　UPS是什么意思?

　　UPS是不(bu)間(jian)斷電源(Uninterruptible Power Supply)的縮寫。

　　UPS不間(jian)斷(duan)電(dian)(dian)源是一種保障設(she)備在電(dian)(dian)網(wang)停(ting)電(dian)(dian)或電(dian)(dian)壓不穩定時繼續供電(dian)(dian)的設(she)備,它具有電(dian)(dian)池作為備用電(dian)(dian)源，當電(dian)(dian)網(wang)停(ting)電(dian)(dian)時，它可(ke)以立即切換供電(dian)(dian)，確保設(she)備的穩定運行。

　　UPS的作用主要有(you)兩個(ge)方面：一是提供(gong)電(dian)(dian)源的穩定(ding)性和連(lian)續性，避免設(she)(she)備(bei)(bei)因電(dian)(dian)力故障引(yin)起的中斷，保(bao)護設(she)(she)備(bei)(bei)的正(zheng)常運行;二是在停(ting)電(dian)(dian)后，給予用戶(hu)足夠的時(shi)間來保(bao)存數(shu)據并(bing)有(you)序關(guan)閉設(she)(she)備(bei)(bei)，保(bao)護數(shu)據的完整(zheng)性;UPS廣泛應用于各(ge)種關(guan)鍵設(she)(she)備(bei)(bei)，如計(ji)算機、服(fu)務器(qi)、通(tong)信設(she)(she)備(bei)(bei)、醫療設(she)(she)備(bei)(bei)等，可(ke)以在電(dian)(dian)網故障或(huo)停(ting)電(dian)(dian)時(shi)提供(gong)穩定(ding)可(ke)靠的電(dian)(dian)源，確保(bao)設(she)(she)備(bei)(bei)正(zheng)常運行，并(bing)保(bao)護數(shu)據和設(she)(she)備(bei)(bei)的安全。

　　EPS電源和UPS的區別是什么?

　　EPS電(dian)源與UPS電(dian)源(Uninterruptible Power Supply，即不間斷(duan)電(dian)源)在功能(neng)上有一定(ding)的相似性，都是(shi)為了在市電(dian)斷(duan)電(dian)時，為關鍵負載提供持(chi)續、穩定(ding)的電(dian)力(li)。但它們在應用場景、工作原理、性能(neng)要求(qiu)等方面，存在較大的差異，那EPS電(dian)源和UPS的區別(bie)是(shi)什么?

　　1、首先EPS電(dian)(dian)(dian)源主要應用于消防(fang)、安(an)全(quan)等關鍵(jian)領域(yu)，它強(qiang)調的(de)是(shi)在市電(dian)(dian)(dian)斷電(dian)(dian)(dian)時(shi)，能(neng)夠迅速(su)、可靠地(di)切換(huan)至蓄(xu)電(dian)(dian)(dian)池供電(dian)(dian)(dian)，保(bao)證消防(fang)設備、安(an)全(quan)系統的(de)正常運(yun)行。而UPS電(dian)(dian)(dian)源則廣泛應用于計(ji)算(suan)機、通信、精(jing)密儀器(qi)等領域(yu)，它強(qiang)調的(de)是(shi)在任(ren)何情況下，都能(neng)夠為負載提供高質量、穩定的(de)電(dian)(dian)(dian)力，保(bao)證負載的(de)正常運(yun)行。

　　2、其次在工作(zuo)原理上，EPS電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)在市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)正常(chang)時，負(fu)載直(zhi)接由(you)市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，逆(ni)(ni)變(bian)器(qi)(qi)處(chu)于待(dai)機狀(zhuang)態(tai)(tai);當市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)斷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時，切(qie)換至蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，由(you)逆(ni)(ni)變(bian)器(qi)(qi)向負(fu)載供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。而UPS電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)則是在市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)正常(chang)時，由(you)市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)提供(gong)(gong)(gong)(gong)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，經(jing)(jing)過(guo)逆(ni)(ni)變(bian)器(qi)(qi)轉換為(wei)(wei)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，為(wei)(wei)負(fu)載供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian);當市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)斷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時，由(you)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)提供(gong)(gong)(gong)(gong)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，經(jing)(jing)過(guo)逆(ni)(ni)變(bian)器(qi)(qi)轉換為(wei)(wei)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，為(wei)(wei)負(fu)載供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。UPS電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)在任何情況下，逆(ni)(ni)變(bian)器(qi)(qi)都處(chu)于工作(zuo)狀(zhuang)態(tai)(tai)，保證負(fu)載的無間斷供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

　　3、再次在(zai)性能要求(qiu)上，EPS電(dian)(dian)源強調的是切換(huan)速(su)度、可靠性，以保證(zheng)在(zai)市(shi)電(dian)(dian)斷電(dian)(dian)時，能夠(gou)迅速(su)、可靠地切換(huan)至蓄電(dian)(dian)池供電(dian)(dian)。而UPS電(dian)(dian)源則強調的是輸出電(dian)(dian)壓(ya)、頻率(lv)的穩定性，以及(ji)輸出波(bo)形的純正性，以保證(zheng)負載(zai)在(zai)任何情況下，都能夠(gou)獲得(de)高質量(liang)、穩定的電(dian)(dian)力(li)。

　　4、此外(wai)EPS電(dian)(dian)源和UPS電(dian)(dian)源在(zai)設(she)備組(zu)成、技術要(yao)求(qiu)(qiu)、應(ying)用(yong)標準等(deng)(deng)方面，也存在(zai)較大的差異。EPS電(dian)(dian)源通常由整流器(qi)、逆(ni)變器(qi)、蓄電(dian)(dian)池(chi)、控(kong)(kong)制系(xi)統等(deng)(deng)部分(fen)(fen)組(zu)成，技術要(yao)求(qiu)(qiu)相對較低(di)，應(ying)用(yong)標準主(zhu)要(yao)是(shi)滿(man)足消(xiao)防、安全等(deng)(deng)領域的特殊要(yao)求(qiu)(qiu)。而UPS電(dian)(dian)源則由整流器(qi)、逆(ni)變器(qi)、蓄電(dian)(dian)池(chi)、控(kong)(kong)制系(xi)統、濾波器(qi)等(deng)(deng)部分(fen)(fen)組(zu)成，技術要(yao)求(qiu)(qiu)較高，應(ying)用(yong)標準主(zhu)要(yao)是(shi)滿(man)足計(ji)算機、通信、精密儀器(qi)等(deng)(deng)領域的高質量電(dian)(dian)力需求(qiu)(qiu)。

　　5、安全規范不(bu)(bu)同：UPS不(bu)(bu)間斷(duan)電(dian)源(yuan)主要用(yong)(yong)來(lai)保(bao)護用(yong)(yong)戶設備或業(ye)務免(mian)受(shou)經濟(ji)損失，其產(chan)(chan)品技術(shu)認證(zheng)主要有泰爾認證(zheng)，CQC認證(zheng)等。而EPS電(dian)源(yuan)的發展是起(qi)源(yuan)于電(dian)網突發故障(zhang)時，為(wei)確(que)保(bao)電(dian)力保(bao)障(zhang)和(he)消防聯動的需要，它(ta)能即時提供逃生照明(ming)和(he)消防應急，保(bao)護用(yong)(yong)戶生命或身(shen)體免(mian)受(shou)傷害，其產(chan)(chan)品技術(shu)要求受(shou)公(gong)安部(bu)消防認證(zheng)監督(du)，并接受(shou)安裝現場消防驗(yan)收。兩者適用(yong)(yong)的安全規范明(ming)顯不(bu)(bu)同，因(yin)而具有不(bu)(bu)同的價值觀。

　　6、性能(neng)優(you)(you)先不同：UPS電(dian)(dian)(dian)(dian)源和EPS電(dian)(dian)(dian)(dian)源均能(neng)提(ti)供兩路選擇輸出供電(dian)(dian)(dian)(dian)，UPS電(dian)(dian)(dian)(dian)源為保證供電(dian)(dian)(dian)(dian)優(you)(you)質，在(zai)線(xian)式UPS選擇逆(ni)變(bian)(bian)優(you)(you)先; 而EPS電(dian)(dian)(dian)(dian)源是(shi)為保證安全，日常使用(yong)考慮節能(neng)性，是(shi)選擇市(shi)電(dian)(dian)(dian)(dian)優(you)(you)先。當然兩者在(zai)整流/充電(dian)(dian)(dian)(dian)器和逆(ni)變(bian)(bian)器的設計(ji)指標上是(shi)有差異的。

　　7、使用(yong)方式不(bu)同：UPS電(dian)源(yuan)由于(yu)是(shi)在(zai)線(xian)式使用(yong)，出現故(gu)(gu)障可以及時(shi)報(bao)警，并有市電(dian)作后(hou)備保障，使用(yong)者能及時(shi)掌握故(gu)(gu)障并排除故(gu)(gu)障，不(bu)會對事故(gu)(gu)造成更(geng)大的損(sun)失。而EPS電(dian)源(yuan)是(shi)離線(xian)式使用(yong)，是(shi)最后(hou)一(yi)道供電(dian)保障，因而其可靠性(xing)設計要(yao)求更(geng)高，不(bu)能簡單理解為后(hou)備式UPS，否則就把EPS電(dian)源(yuan)的重要(yao)性(xing)一(yi)筆勾(gou)銷了。如果EPS在(zai)市電(dian)故(gu)(gu)障時(shi)，不(bu)能通(tong)過蓄電(dian)池應急(ji)供電(dian)，則EPS如同虛設，造成的后(hou)果將不(bu)堪設想。

　　8、供(gong)電(dian)(dian)(dian)對(dui)(dui)象不(bu)同：UPS電(dian)(dian)(dian)源(yuan)(yuan)供(gong)電(dian)(dian)(dian)對(dui)(dui)象是(shi)計(ji)(ji)算機及(ji)網絡(luo)設(she)備，負載(zai)(zai)(zai)性質(輸(shu)(shu)入功率因(yin)數)差別不(bu)大，所以(yi)國標規定(ding)UPS電(dian)(dian)(dian)源(yuan)(yuan)輸(shu)(shu)出功因(yin)為0.8。而EPS供(gong)電(dian)(dian)(dian)對(dui)(dui)象則是(shi)電(dian)(dian)(dian)力(li)保障及(ji)消防安全，負載(zai)(zai)(zai)性質為感性、容(rong)性及(ji)整流(liu)式非(fei)線性負載(zai)(zai)(zai)兼而有之，其輸(shu)(shu)出功率因(yin)數就不(bu)能(neng)設(she)定(ding)為0.8(EPS國標將規定(ding)其數值)，而且(qie)有些負載(zai)(zai)(zai)是(shi)停市(shi)電(dian)(dian)(dian)后(hou)才投入工作的，因(yin)而要求EPS能(neng)提供(gong)很大的沖擊(ji)電(dian)(dian)(dian)流(liu)，EPS電(dian)(dian)(dian)源(yuan)(yuan)需要輸(shu)(shu)出動態特性要好，抗(kang)過載(zai)(zai)(zai)能(neng)力(li)更強。因(yin)此EPS電(dian)(dian)(dian)源(yuan)(yuan)與UPS電(dian)(dian)(dian)源(yuan)(yuan)各(ge)組成部(bu)分(fen)(fen)的技術設(she)計(ji)(ji)指標分(fen)(fen)配是(shi)不(bu)同的。

　　以上就(jiu)是(shi)EPS電(dian)(dian)源是(shi)什(shen)么意(yi)思，EPS電(dian)(dian)源和UPS的(de)(de)區別是(shi)什(shen)么的(de)(de)介(jie)紹(shao),EPS電(dian)(dian)源和UPS電(dian)(dian)源雖然都是(shi)為了在(zai)市電(dian)(dian)斷電(dian)(dian)時，為關鍵負(fu)載提供(gong)持續、穩定的(de)(de)電(dian)(dian)力，但它們(men)在(zai)應用(yong)場(chang)景、工作原理、性能要(yao)求(qiu)、設備組成(cheng)、技(ji)術要(yao)求(qiu)、應用(yong)標準等方面，存(cun)在(zai)較大的(de)(de)差異。因此，在(zai)實際(ji)應用(yong)中，應根據具(ju)體的(de)(de)需求(qiu)，選擇合(he)適的(de)(de)電(dian)(dian)源設備。
