一、EPS應急電源供電持續多長時間

EPS應急電源是一種用于應(ying)對突發停電(dian)(dian)情況(kuang)的(de)(de)重要設(she)(she)備(bei)，它在供(gong)電(dian)(dian)中(zhong)斷時(shi)(shi)能夠(gou)提(ti)供(gong)繼續(xu)供(gong)電(dian)(dian)的(de)(de)功能，確(que)保關鍵設(she)(she)備(bei)的(de)(de)正常運(yun)行。EPS消防(fang)應(ying)急(ji)電(dian)(dian)源(yuan)可(ke)以為(wei)消防(fang)逃生提(ti)供(gong)應(ying)急(ji)照明。那(nei)么EPS應(ying)急(ji)電(dian)(dian)源(yuan)供(gong)電(dian)(dian)持續(xu)多長時(shi)(shi)間(jian)？

EPS應急電源(yuan)持續供(gong)電時間需(xu)要(yao)(yao)視具體情況而定(ding)。根據(ju)《消防應急照明(ming)和疏散(san)指示系統 GB17945-2010》規定(ding)，在市電中斷時，EPS應急電源(yuan)可(ke)以持續供(gong)電不能低于90分(fen)鐘，這不僅滿足在發生(sheng)火(huo)災(zai)疏散(san)時的應急照明(ming)，也要(yao)(yao)為消防人員的救援照明(ming)等需(xu)要(yao)(yao)。

一般情況下(xia)，普通照明燈(deng)的EPS應(ying)(ying)(ying)急(ji)電(dian)(dian)源(yuan)的供(gong)電(dian)(dian)中斷時間(jian)不(bu)(bu)(bu)能(neng)(neng)超過5秒(miao)。對于高危險工(gong)作區及關鍵(jian)工(gong)作區的應(ying)(ying)(ying)急(ji)照明，EPS應(ying)(ying)(ying)急(ji)電(dian)(dian)源(yuan)的供(gong)電(dian)(dian)中斷時間(jian)不(bu)(bu)(bu)能(neng)(neng)超過0.25秒(miao)。EPS應(ying)(ying)(ying)急(ji)電(dian)(dian)源(yuan)的最長(chang)充(chong)電(dian)(dian)時間(jian)不(bu)(bu)(bu)能(neng)(neng)超過24小時，且連續過充(chong)電(dian)(dian)電(dian)(dian)流不(bu)(bu)(bu)能(neng)(neng)超過0.05C5A。

根據《民(min)用建筑電(dian)氣設計標準(zhun) GB51348-2019》規定，部(bu)分消防設備對EPS應急電(dian)源(yuan)也有著不(bu)同的供電(dian)時間(jian)要求(qiu)：

火災自動報警裝置不能低于180（120）分鐘。

消火栓、消防泵及水幕泵不能低于(yu)180（120）分鐘。

自動(dong)噴水系統不能(neng)低于60分(fen)鐘。

水噴霧(wu)和(he)泡沫滅火系統不能低于30分鐘。

滅火和干粉滅火系統不能低于30分鐘(zhong)。

防、排煙設(she)備不能(neng)低(di)于90、60、30分(fen)鐘。

火災(zai)應急廣播不能低于90、60、30分鐘。

消防電梯不能低于(yu)180（120）分鐘。

由此可(ke)見(jian)，EPS應(ying)急(ji)電(dian)源(yuan)持續(xu)供電(dian)時間(jian)對(dui)不同的消(xiao)防設備(bei)也(ye)有(you)著不一樣的要(yao)(yao)求，所(suo)以(yi)在采購EPS消(xiao)防應(ying)急(ji)電(dian)源(yuan)時，一定要(yao)(yao)弄清楚(chu)其使(shi)用(yong)場(chang)所(suo)及(ji)相(xiang)關(guan)的要(yao)(yao)求規定。此外(wai)，定期檢查和(he)維護EPS應(ying)急(ji)電(dian)源(yuan)也(ye)是確(que)保其正常工作和(he)延長供電(dian)時間(jian)的重要(yao)(yao)措施。

二、EPS消防應急電源標準新要求

8、應急照明集中EPS電源在下(xia)述情況下(xia)應(ying)(ying)(ying)發出故(gu)障(zhang)(zhang)(zhang)(zhang)聲、光(guang)信(xin)號(hao)，并指示故(gu)障(zhang)(zhang)(zhang)(zhang)的類型；故(gu)障(zhang)(zhang)(zhang)(zhang)聲信(xin)號(hao)應(ying)(ying)(ying)能手動消除(chu)，當(dang)有新(xin)的故(gu)障(zhang)(zhang)(zhang)(zhang)信(xin)號(hao)時，故(gu)障(zhang)(zhang)(zhang)(zhang)聲信(xin)號(hao)應(ying)(ying)(ying)再啟動；故(gu)障(zhang)(zhang)(zhang)(zhang)光(guang)信(xin)號(hao)在故(gu)障(zhang)(zhang)(zhang)(zhang)排(pai)除(chu)前應(ying)(ying)(ying)保持。故(gu)障(zhang)(zhang)(zhang)(zhang)條件如下(xia)所述：
