1、電能計量

　　多(duo)用(yong)戶(hu)電(dian)(dian)能(neng)表可計(ji)量每(mei)一用(yong)戶(hu)總用(yong)電(dian)(dian)量(正(zheng)(zheng)向(xiang)+反(fan)向(xiang))、正(zheng)(zheng)向(xiang)用(yong)電(dian)(dian)量和反(fan)向(xiang)用(yong)電(dian)(dian)量。

2、繼電器控制(僅限預付(fu)費(fei)型)

　　2.1 無費(fei)關斷(預(yu)付費(fei)控制)

　　多用(yong)(yong)(yong)(yong)戶電(dian)(dian)(dian)(dian)能(neng)表可(ke)(ke)設置報(bao)警電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)1和報(bao)警電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)2。當(dang)用(yong)(yong)(yong)(yong)戶用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)時(shi)，遞增(zeng)用(yong)(yong)(yong)(yong)戶總用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)，并遞減用(yong)(yong)(yong)(yong)戶剩(sheng)余(yu)電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)。當(dang)用(yong)(yong)(yong)(yong)戶剩(sheng)余(yu)電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)小(xiao)(xiao)于(yu)報(bao)警電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)1時(shi)，LCD顯示“請購電(dian)(dian)(dian)(dian)”，剩(sheng)余(yu)電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)小(xiao)(xiao)于(yu)報(bao)警電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)2時(shi)，電(dian)(dian)(dian)(dian)能(neng)表自動拉閘(zha)斷(duan)(duan)電(dian)(dian)(dian)(dian)，一段時(shi)間(jian)后(hou)(hou)可(ke)(ke)恢復(fu)(fu)供(gong)電(dian)(dian)(dian)(dian)。恢復(fu)(fu)時(shi)間(jian)可(ke)(ke)設為(wei)0-255s，值(zhi)為(wei)0不斷(duan)(duan)電(dian)(dian)(dian)(dian)，若(ruo)值(zhi)為(wei)255，則斷(duan)(duan)電(dian)(dian)(dian)(dian)后(hou)(hou)不恢復(fu)(fu)供(gong)電(dian)(dian)(dian)(dian)。剩(sheng)余(yu)電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)小(xiao)(xiao)于(yu)0后(hou)(hou)的用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)計(ji)入透支金(jin)(jin)額，當(dang)透支金(jin)(jin)額大于(yu)設定值(zhi)時(shi)，切(qie)斷(duan)(duan)該用(yong)(yong)(yong)(yong)戶供(gong)電(dian)(dian)(dian)(dian)，只有(you)用(yong)(yong)(yong)(yong)戶購電(dian)(dian)(dian)(dian)后(hou)(hou)才(cai)可(ke)(ke)恢復(fu)(fu)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)。

　　2.2 定(ding)時斷電(時控(kong))

　　多(duo)用(yong)戶電(dian)(dian)能(neng)表可對用(yong)戶用(yong)電(dian)(dian)進行時(shi)間控(kong)制，電(dian)(dian)能(neng)表通過后臺管理(li)軟(ruan)件，設(she)定自動斷(duan)電(dian)(dian)、上(shang)電(dian)(dian)時(shi)間，方便(bian)對用(yong)戶的用(yong)電(dian)(dian)管理(li)。

　　2.3 超負荷斷電(負控)

　　多用(yong)戶(hu)電(dian)(dian)能表可設置用(yong)戶(hu)的(de)z大負(fu)荷功(gong)(gong)率(lv)，當用(yong)戶(hu)的(de)實際功(gong)(gong)率(lv)大于設定值(zhi)時(shi)，電(dian)(dian)能表自(zi)動(dong)切(qie)斷該(gai)戶(hu)供電(dian)(dian)電(dian)(dian)路，功(gong)(gong)率(lv)未(wei)超(chao)過(guo)z大負(fu)荷功(gong)(gong)率(lv)設定值(zhi)，并且客(ke)戶(hu)有惡(e)性負(fu)載識別需求，電(dian)(dian)能表可自(zi)動(dong)判斷，如判斷是惡(e)性負(fu)載，則(ze)切(qie)斷該(gai)用(yong)戶(hu)供電(dian)(dian)，一段(duan)時(shi)間后(可設定)，可自(zi)動(dong)恢(hui)復(fu)(fu)供電(dian)(dian)，當恢(hui)復(fu)(fu)次數(shu)超(chao)過(guo)設定值(zhi)時(shi)，不能自(zi)動(dong)恢(hui)復(fu)(fu)供電(dian)(dian)，用(yong)戶(hu)必須(xu)手(shou)動(dong)清零(ling)恢(hui)復(fu)(fu)次數(shu)方(fang)可供電(dian)(dian)。

　　2.4 強(qiang)制斷(duan)電(dian) (強(qiang)控)

　　多用(yong)戶電能表可由(you)后臺(tai)管(guan)理系統對(dui)用(yong)戶進行強制斷電、送電控制，使管(guan)理中心可以(yi)及(ji)時地處理突發事件(jian)。

　　注意：以上(shang)四(si)種(zhong)控制中(zhong)，當強控打開時，其它控制均(jun)無效。
