技術要求(qiu)

????????超(chao)級電容智(zhi)能(neng)監(jian)(jian)控管理模(mo)(mo)塊(kuai)須(xu)對超(chao)級電容器(qi)模(mo)(mo)組進行實時監(jian)(jian)測并(bing)提供全方位的保護。須(xu)對每個超(chao)級電容器(qi)模(mo)(mo)組的電壓，溫(wen)度等信(xin)息實時監(jian)(jian)測并(bing)顯示(shi)在(zai)主(zhu)監(jian)(jian)控屏上。當檢測到(dao)超(chao)級電容器(qi)模(mo)(mo)組過(guo)壓，過(guo)流及過(guo)溫(wen)時應能(neng)實時切斷輸(shu)入或輸(shu)出。

????????當(dang)交流電(dian)(dian)失(shi)電(dian)(dian)時（超級(ji)電(dian)(dian)容(rong)器(qi)已(yi)充滿電(dian)(dian)），超級(ji)電(dian)(dian)容(rong)器(qi)應保證分合(he)閘操作(zuo)15次(ci)后，維持配電(dian)(dian)終端，15套保護裝置及通訊模塊至少運行90分鐘。超級(ji)電(dian)(dian)容(rong)器(qi)完全放完電(dian)(dian)的(de)情況下，充電(dian)(dian)60s內(nei)，系(xi)統(tong)應能正(zheng)常工作(zuo)（即此時可(ke)以(yi)進行分合(he)閘操作(zuo)并(bing)維持配電(dian)(dian)終端，15套保護裝置及通訊模塊的(de)正(zheng)常運行）。

????????當交流電(dian)(dian)(dian)(dian)(dian)失電(dian)(dian)(dian)(dian)(dian)時，超(chao)(chao)級(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)容器開始放(fang)電(dian)(dian)(dian)(dian)(dian)，放(fang)電(dian)(dian)(dian)(dian)(dian)至185VDC±5V時應啟用穩(wen)(wen)壓模(mo)塊(kuai)，使直流負(fu)載輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓穩(wen)(wen)定在(zai)230VDC±2V,且超(chao)(chao)級(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)容器放(fang)電(dian)(dian)(dian)(dian)(dian)至40V±2V時，穩(wen)(wen)壓模(mo)塊(kuai)仍能正常輸(shu)出230VDC±2V。因(yin)前端(duan)交流供(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源(yuan)輸(shu)出功率的(de)(de)限(xian)制，為盡量縮短(duan)超(chao)(chao)級(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)容器的(de)(de)充電(dian)(dian)(dian)(dian)(dian)時間，須采(cai)用分(fen)段充電(dian)(dian)(dian)(dian)(dian)控制技術，且分(fen)段電(dian)(dian)(dian)(dian)(dian)壓及充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流可設。如(ru)：交流輸(shu)入電(dian)(dian)(dian)(dian)(dian)源(yuan)功率5KVA,則(ze)超(chao)(chao)級(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)容器電(dian)(dian)(dian)(dian)(dian)壓從0V充到100V時，充電(dian)電(dian)流可放開至(zhi)40A。

????超(chao)級電(dian)容，超(chao)級電(dian)容智能監控管理模(mo)(mo)塊，充電(dian)模(mo)(mo)塊，穩壓模(mo)(mo)塊，放電(dian)模(mo)(mo)塊等均(jun)安裝在一面超(chao)級電(dian)容儲能(neng)柜中。且整面屏中不能(neng)出現鉛酸蓄電(dian)池或鋰電(dian)池（監控板上的鈕(niu)扣電(dian)池除外(wai)）。

工作溫度范圍：-40度~65度。
