一、EPS應急電源有哪些組成部分

EPS應急電源主要(yao)由整流充電(dian)(dian)器(qi)(qi)(qi)、蓄電(dian)(dian)池組(zu)、逆(ni)變(bian)器(qi)(qi)(qi)、互投裝置和系(xi)統(tong)(tong)控(kong)(kong)制器(qi)(qi)(qi)等部分組(zu)成(cheng)。其中(zhong)，逆(ni)變(bian)器(qi)(qi)(qi)是(shi)(shi)核心部分，作用(yong)(yong)是(shi)(shi)將蓄電(dian)(dian)池組(zu)存儲(chu)的(de)直(zhi)流電(dian)(dian)能(neng)變(bian)換成(cheng)交流電(dian)(dian)輸(shu)(shu)出(chu)，供(gong)給負載設備穩定(ding)持續的(de)電(dian)(dian)力。整流充電(dian)(dian)器(qi)(qi)(qi)的(de)作用(yong)(yong)是(shi)(shi)在(zai)市電(dian)(dian)輸(shu)(shu)入正(zheng)常時(shi)(shi)，對蓄電(dian)(dian)池組(zu)進行適時(shi)(shi)充電(dian)(dian)。互投裝置則保(bao)證負載在(zai)市電(dian)(dian)及逆(ni)變(bian)器(qi)(qi)(qi)輸(shu)(shu)出(chu)間的(de)順利切換。系(xi)統(tong)(tong)控(kong)(kong)制器(qi)(qi)(qi)負責整個系(xi)統(tong)(tong)的(de)實時(shi)(shi)控(kong)(kong)制，可(ke)以發出(chu)故障告警信號(hao)和接(jie)收遠(yuan)程聯動控(kong)(kong)制信號(hao)，同(tong)時(shi)(shi)還可(ke)通過標(biao)準通訊(xun)接(jie)口實現EPS系(xi)統(tong)(tong)的(de)遠(yuan)程監控(kong)(kong)。

除了以(yi)(yi)上核(he)心部分(fen)，EPS應急(ji)電(dian)(dian)源(yuan)(yuan)還包(bao)括輸(shu)(shu)(shu)入(ru)(ru)輸(shu)(shu)(shu)出(chu)(chu)單(dan)元、充(chong)電(dian)(dian)模塊(kuai)、電(dian)(dian)池(chi)組(zu)、監控(kong)器(qi)等組(zu)成部分(fen)。其中，輸(shu)(shu)(shu)入(ru)(ru)輸(shu)(shu)(shu)出(chu)(chu)單(dan)元負(fu)責(ze)市電(dian)(dian)與EPS應急(ji)電(dian)(dian)源(yuan)(yuan)之間的(de)(de)輸(shu)(shu)(shu)入(ru)(ru)輸(shu)(shu)(shu)出(chu)(chu)切換，電(dian)(dian)池(chi)組(zu)則(ze)是(shi)(shi)存儲直流電(dian)(dian)能的(de)(de)裝(zhuang)置，為逆變器(qi)提供直流電(dian)(dian)源(yuan)(yuan)。充(chong)電(dian)(dian)模塊(kuai)則(ze)是(shi)(shi)對電(dian)(dian)池(chi)組(zu)進行(xing)充(chong)電(dian)(dian)的(de)(de)設(she)備，監控(kong)器(qi)則(ze)是(shi)(shi)對整個EPS應急(ji)電(dian)(dian)源(yuan)(yuan)進行(xing)監控(kong)和管理的(de)(de)設(she)備，可以(yi)(yi)實時監測(ce)電(dian)(dian)源(yuan)(yuan)狀(zhuang)態、電(dian)(dian)池(chi)電(dian)(dian)量、負(fu)載情(qing)況等信息，并通(tong)過人機界面(mian)進行(xing)顯示(shi)和設(she)置。

此(ci)外，針對不同(tong)負載和(he)應(ying)用場景(jing)，EPS應(ying)急(ji)電源(yuan)還可以(yi)配(pei)備(bei)不同(tong)的功能模塊，如消防(fang)聯動接口、智能電池管理、防(fang)雷保(bao)護等，以(yi)滿足更(geng)為復雜和(he)精(jing)細的電力保(bao)障需(xu)求(qiu)。需(xu)要(yao)注(zhu)意的是，在選擇(ze)和(he)使用EPS應(ying)急(ji)電源(yuan)時，需(xu)要(yao)遵循負載容量選型原則(ze)，同(tong)時要(yao)考慮EPS應(ying)急(ji)電源(yuan)的備(bei)用時間等因素，以(yi)確(que)保(bao)其能夠滿足應(ying)急(ji)情況下的電力需(xu)求(qiu)。

二、eps電源的工作原理

1、當市電正常時，由市電經過互投裝置給重要負載供電，同時進行市電檢測及蓄電池充電管理，然后再由電池組向逆變器提供直流能源。在這里，充電器是一個僅需向蓄電池組提供相當于10%蓄電池組容量（Ah）的充電電流的小功率直流電源，它并不具備直接向逆變器提供直流電源的能力。此時，市電經由EPS的交流旁路和轉換開關所組成的供電系統向用戶的各種應急負載供電。與此同時，在EPS的邏輯控制板的調控下，逆變器停止工作處于自動關機狀態。在此條件下，用戶負載實際使用的電源是來自電網的市電，因此，EPS應急電源也(ye)是通常(chang)說(shuo)的一直工作在(zai)睡眠(mian)狀態，可以有效的達到節(jie)能的效果。

2、當市電(dian)(dian)供電(dian)(dian)中斷或市電(dian)(dian)電(dian)(dian)壓超限（±15%或±20%額(e)定輸入(ru)電(dian)(dian)壓）時，互投(tou)裝(zhuang)置(zhi)將立即投(tou)切至逆變(bian)器(qi)供電(dian)(dian)，在電(dian)(dian)池組所(suo)提供的直流(liu)能源的支持下，此時，用(yong)戶負載所(suo)使(shi)用(yong)的電(dian)(dian)源是通(tong)過EPS的逆變(bian)器(qi)轉換(huan)的交流(liu)電(dian)(dian)源，而(er)不是來(lai)自市電(dian)(dian)。

3、當(dang)市電(dian)(dian)電(dian)(dian)壓恢復正(zheng)常工(gong)作時，EPS的(de)(de)控(kong)制中心發出信號(hao)對逆變(bian)器執行自動關(guan)(guan)機(ji)操(cao)作，同(tong)時還通(tong)過它的(de)(de)轉換開關(guan)(guan)執行從(cong)逆變(bian)器供(gong)電(dian)(dian)向(xiang)交流(liu)旁路(lu)供(gong)電(dian)(dian)的(de)(de)切換操(cao)作。此后，EPS在經(jing)交流(liu)旁路(lu)供(gong)電(dian)(dian)通(tong)路(lu)向(xiang)負(fu)載提(ti)供(gong)市電(dian)(dian)的(de)(de)同(tong)時，還通(tong)過充電(dian)(dian)器向(xiang)電(dian)(dian)池組充電(dian)(dian)。

4、除(chu)用于(yu)應急照明系統(tong)外，其中(zhong)三相智(zhi)能化變頻應急電(dian)源(yuan)主要是為一(yi)級負荷(he)中(zhong)的電(dian)動(dong)(dong)機提供一(yi)種(zhong)可(ke)變頻的應急電(dian)源(yuan)系統(tong)，該(gai)產品方便解決了電(dian)動(dong)(dong)機的應急供電(dian)及其啟動(dong)(dong)過程中(zhong)對供電(dian)設備的沖擊影響。智(zhi)能化應急電(dian)源(yuan)可(ke)接受消(xiao)防(fang)聯動(dong)(dong)信號(hao)、建筑智(zhi)能總線信號(hao)控(kong)制，并(bing)可(ke)設定優(you)先級，防(fang)止越級控(kong)制。
