EPS消防(fang)應急電源是什么?

  EPS(EmergencyPowerSupply)它是(shi)一種應急(ji)電(dian)源(yuan)(yuan)(yuan)，EPS應急(ji)電(dian)源(yuan)(yuan)(yuan)是(shi)一種由(you)消防設施、應急(ji)照明、事故照明等一級(ji)負(fu)(fu)載供(gong)電(dian)設備組成(cheng)(cheng)的電(dian)源(yuan)(yuan)(yuan)設備。該產品由(you)互(hu)投(tou)(tou)裝(zhuang)置(zhi)(zhi)、自動(dong)充電(dian)器、逆變器和電(dian)池組組成(cheng)(cheng)。當(dang)交流電(dian)網正常時(shi)，逆變器不工(gong)作(zuo)，通過互(hu)投(tou)(tou)裝(zhuang)置(zhi)(zhi)向重要(yao)負(fu)(fu)載供(gong)電(dian)。當(dang)交流電(dian)網斷電(dian)時(shi)，互(hu)投(tou)(tou)裝(zhuang)置(zhi)(zhi)將立(li)即切入逆變電(dian)源(yuan)(yuan)(yuan)供(gong)電(dian)。當(dang)電(dian)網電(dian)壓恢復時(shi)，互(hu)投(tou)(tou)裝(zhuang)置(zhi)(zhi)將切入交流電(dian)網供(gong)電(dian)。EPS電(dian)源(yuan)(yuan)(yuan)可分(fen)為三類:應急(ji)照明、動(dong)力和動(dong)力變頻。

  UPS不間斷(duan)電源是什么?

  UPS(uninterruptiblepowersystem)它是一種系統(tong)設備，通過主機逆變器(qi)等(deng)模塊電(dian)(dian)路(lu)將(jiang)電(dian)(dian)池(多(duo)為(wei)鉛酸免(mian)維護電(dian)(dian)池)與主機連接，將(jiang)DC電(dian)(dian)路(lu)轉換為(wei)市電(dian)(dian)。主要用于為(wei)電(dian)(dian)磁閥、壓力(li)變送器(qi)等(deng)單臺計算機、計算機網絡系統(tong)或其他電(dian)(dian)力(li)電(dian)(dian)子(zi)設備提(ti)供穩定不(bu)間(jian)斷(duan)的電(dian)(dian)力(li)供應。根據工作原理，UPS可分(fen)為(wei)三類:后備式、在(zai)線(xian)式和在(zai)線(xian)互動式。

  EPS電(dian)源與UPS電(dian)源使用場合的區別(bie)

  EPS被稱為“城市生(sheng)命(ming)線系統”的重(zhong)要(yao)組(zu)成(cheng)部(bu)分，廣(guang)泛應(ying)(ying)用(yong)于建(jian)筑電(dian)氣(qi)領域、應(ying)(ying)急照明(ming)、消防等需(xu)要(yao)應(ying)(ying)急供電(dian)的場合。從機關、企業(ye)、事業(ye)單位和民用(yong)建(jian)筑的使用(yong)來看，僅僅依靠(kao)市電(dian)供電(dian)是遠(yuan)遠(yuan)不夠的。必須有應(ying)(ying)急供電(dian)系統EPS。其重(zhong)要(yao)性在于確保(bao)事故發(fa)生(sheng)時提供所需(xu)的應(ying)(ying)急電(dian)力，有效減少斷電(dian)造成(cheng)的損失，保(bao)證人們(men)的生(sheng)產和生(sheng)活安(an)全。UPS廣(guang)泛應(ying)(ying)用(yong)于IT行(xing)業(ye)和特(te)殊精密設備(bei)，從信息采集、傳(chuan)輸、處理、存儲(chu)和應(ying)(ying)用(yong)的重(zhong)要(yao)環節遍(bian)布。

  EPS應(ying)急電源與UPS電源的(de)區別

  當市(shi)電正常時(shi)(shi)，各種EPS電源通(tong)過(guo)(guo)旁路直接為(wei)(wei)負載提(ti)供(gong)市(shi)電。UPS電源中的后(hou)備(bei)UPS和(he)(he)在線(xian)互動(dong)UPS通(tong)過(guo)(guo)旁路為(wei)(wei)負載提(ti)供(gong)調節和(he)(he)凈化的市(shi)電，而UPS電源中的在線(xian)UPS總是(沒有時(shi)(shi)間間隔)為(wei)(wei)負載提(ti)供(gong)與市(shi)電同(tong)頻、相同(tong)、誤(wu)差小的純逆(ni)變交流電。當市(shi)電中斷時(shi)(shi)，EPS和(he)(he)UPS為(wei)(wei)負載提(ti)供(gong)逆(ni)變交流電。為(wei)(wei)了(le)更好地保(bao)護信息和(he)(he)設備(bei)，當市(shi)電異(yi)常時(shi)(shi)，UPS將提(ti)供(gong)更多(duo)的逆(ni)變交流電，包括電涌、高壓(ya)尖脈沖、暫時(shi)(shi)過(guo)(guo)壓(ya)、電壓(ya)下沉、電線(xian)噪聲(sheng)和(he)(he)其他電線(xian)頻率(lv)。
