  EPS應急電(dian)(dian)(dian)源是根據消防設(she)(she)施、應急照明(ming)、事故照明(ming)等一(yi)級負(fu)荷供(gong)(gong)電(dian)(dian)(dian)設(she)(she)備(bei)需要(yao)而組成的(de)電(dian)(dian)(dian)源設(she)(she)備(bei)。產(chan)品(pin)由互(hu)(hu)投(tou)裝置(zhi)(zhi)、自動(dong)充電(dian)(dian)(dian)機、逆(ni)變(bian)(bian)器及(ji)蓄電(dian)(dian)(dian)池組等組成。在交流電(dian)(dian)(dian)網(wang)正常時逆(ni)變(bian)(bian)器不(bu)工作,經過互(hu)(hu)投(tou)裝置(zhi)(zhi)給重(zhong)要(yao)負(fu)載供(gong)(gong)電(dian)(dian)(dian)。當(dang)交流電(dian)(dian)(dian)網(wang)斷電(dian)(dian)(dian)后,互(hu)(hu)投(tou)裝置(zhi)(zhi)將會(hui)立即投(tou)切至逆(ni)變(bian)(bian)電(dian)(dian)(dian)源供(gong)(gong)電(dian)(dian)(dian)。當(dang)電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)壓(ya)恢(hui)復時,互(hu)(hu)投(tou)裝置(zhi)(zhi)將會(hui)投(tou)切至交流電(dian)(dian)(dian)網(wang)供(gong)(gong)電(dian)(dian)(dian)。

 

  UPS不間(jian)斷電(dian)(dian)(dian)源(yuan)是將(jiang)電(dian)(dian)(dian)池(大(da)多數免(mian)維護(hu)鉛蓄電(dian)(dian)(dian)池)連(lian)接到(dao)主(zhu)機,并通過(guo)主(zhu)機逆變等模塊電(dian)(dian)(dian)路(lu)將(jiang)直流(liu)轉換為主(zhu)電(dian)(dian)(dian)流(liu)的系(xi)統設備(bei)。主(zhu)要用于為單臺計算機、計算機網絡(luo)系(xi)統或其他電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)子(zi)設備(bei)(例如(ru)電(dian)(dian)(dian)磁閥、壓力(li)變送器等)提供(gong)穩定、不間(jian)斷的電(dian)(dian)(dian)力(li)供(gong)應。當電(dian)(dian)(dian)源(yuan)輸入正常(chang)時,UPS將(jiang)電(dian)(dian)(dian)源(yuan)供(gong)應給負(fu)載。

 

  此(ci)時(shi),UPS是交(jiao)流電(dian)(dian)源(yuan)電(dian)(dian)壓調節器,為內部(bu)電(dian)(dian)池(chi)(chi)充電(dian)(dian)。UPS可在停(ting)電(dian)(dian)時(shi)立(li)即啟動(dong)電(dian)(dian)池(chi)(chi)的直流電(dian)(dian)源(yuan),通過(guo)(guo)逆(ni)變零切(qie)換(huan)繼續向負載提供220V交(jiao)流電(dian)(dian),保(bao)持負載正常(chang)運行,并保(bao)護(hu)軟負載不受硬件損壞的影響。UPS設備通常(chang)可以在電(dian)(dian)壓過(guo)(guo)高或過(guo)(guo)低的情(qing)況下(xia)進行保(bao)護(hu)。

 

  那么EPS應急電(dian)源(yuan)與(yu)UPS電(dian)源(yuan)有什么與(yu)眾不同呢?下面(mian)大(da)成智(zhi)慧(hui)小編來給(gei)大(da)家(jia)介紹下EPS應急電(dian)源(yuan)與(yu)UPS電(dian)源(yuan)的區別。



   EPS應急電源與UPS電源區別:

 

  1、與應(ying)用不同,EPS應(ying)急電(dian)源(yuan)主(zhu)要(yao)用于消(xiao)防行業(ye)電(dian)氣設備(bei),強調持(chi)續電(dian)源(yuan)功能。UPS不間斷電(dian)源(yuan)通(tong)常(chang)用于計(ji)算機、服務器(qi)等IT行業(ye)設備(bei)等精密儀器(qi)負載,要(yao)求高(gao)供電(dian)質量,強調逆變開關時(shi)間、輸出電(dian)壓、頻率穩定性(xing)、輸出波形的純粹性(xing)。

 

  2、與(yu)EPS應(ying)(ying)急(ji)電源(yuan)和(he)UPS不(bu)(bu)間斷(duan)電源(yuan)區(qu)別結構不(bu)(bu)同,EPS應(ying)(ying)急(ji)電源(yuan)逆變器冗馀(yu)、輸入機(ji)柜和(he)插座均位于EPS內(nei)部,電動機(ji)負載有變頻啟動。外(wai)殼(ke)和(he)導線具(ju)有阻燃性,可(ke)與(yu)防火聯系,具(ju)有多通道互投資(zi)功能。UPS不(bu)(bu)間斷(duan)電源(yuan)的逆變器冗馀(yu)與(yu)火災無關(guan),沒有互投資(zi)功能。

 

  EPS應急電源負載(zai)通常(chang)(chang)是具有(you)電動機、照明(ming)、風扇、泵等設備的官(guan)能、電阻、應急消防(fang)產品,是用于(yu)中央應急電源的專用應急消防(fang)照明(ming)電源。UPS不(bu)間斷電源負載(zai)屬于(yu)電容式負載(zai),主皮帶裝置通常(chang)(chang)主要用于(yu)大型機房,確保(bao)不(bu)間斷電源和(he)電壓(ya)調(diao)節(jie)器。

 

  3、功能(neng)EPS應急電源和UPS不間斷電源均(jun)為城(cheng)市(shi)具有旁路(lu)和逆變電路(lu)。功能(neng)上的差異是,EPS應急電源具有持續(xu)電源功能(neng),一(yi)般(ban)對逆變開(kai)關時間要求不高,對于特定應用(yong)(yong)程序,必須(xu)具有多輸出(chu)、每個(ge)輸出(chu)和單個(ge)電池的監控和檢(jian)測(ce)功能(neng)。日常注重旁路(lu)功率(lv),只有當市(shi)外電力中斷時,才(cai)能(neng)轉換(huan)到逆變器,電力利(li)用(yong)(yong)率(lv)高。

 

  UPS電(dian)(dian)(dian)源(yuan)(yuan)通(tong)常(chang)強調(diao)三個(ge)主要功能:(a)電(dian)(dian)(dian)壓調(diao)節(jie);(b)不間(jian)(jian)斷電(dian)(dian)(dian)源(yuan)(yuan);(c)在切換(huan)(huan)時間(jian)(jian)要求極高的(de)(de)情況下,能夠一次性(xing)完成全部輸(shu)出(chu)(例如聯機),以及凈化主電(dian)(dian)(dian)源(yuan)(yuan)。以整流/逆變器為(wei)重點的(de)(de)雙轉換(huan)(huan)電(dian)(dian)(dian)路電(dian)(dian)(dian)源(yuan)(yuan),發生逆變故障或過載(zai)時,轉換(huan)(huan)為(wei)旁路電(dian)(dian)(dian)源(yuan)(yuan),因此功率利用率不高(一般為(wei)80%-90%)。但(dan)是(shi),在國外(wai)電(dian)(dian)(dian)力(li)較好的(de)(de)國家,為(wei)了節(jie)約能源(yuan)(yuan),部分UPS使用場(chang)所已被(bei)逆變開關時間(jian)(jian)很短(小于10毫(hao)秒)的(de)(de)EPS所取代。

 

  以上(shang)內容就是對(dui)(dui)EPS應(ying)急(ji)(ji)電(dian)(dian)源與UPS電(dian)(dian)源有(you)什么(me)與眾不同的(de)介紹(shao)了,EPS消(xiao)防應(ying)急(ji)(ji)電(dian)(dian)源與UPS不間(jian)斷(duan)電(dian)(dian)源有(you)著明顯的(de)區別,加(jia)上(shang)EPS應(ying)急(ji)(ji)電(dian)(dian)源會有(you)幾秒的(de)切(qie)換(huan),而UPS不間(jian)斷(duan)電(dian)(dian)源則是零切(qie)換(huan)的(de),因此對(dui)(dui)于使用(yong)場(chang)所(suo)比較嚴的(de)設備(bei),必須用(yong)UPS而不是EPS,比如醫院ICU重癥(zheng)監護室設備(bei),機房服務器,計算(suan)機等(deng)設備(bei)或者其他需(xu)要用(yong)到(dao)UPS不間(jian)斷(duan)電(dian)(dian)源的(de)場(chang)所(suo)。因此大家在選擇應(ying)急(ji)(ji)電(dian)(dian)源時,針對(dui)(dui)所(suo)需(xu)環(huan)境的(de)要求給出合理的(de)配置,使得設備(bei)發揮更(geng)加(jia)的(de)效(xiao)能。
