1、電能計量

　　多用(yong)戶(hu)電(dian)能表可計量(liang)(liang)每一用(yong)戶(hu)總用(yong)電(dian)量(liang)(liang)(正向(xiang)+反向(xiang))、正向(xiang)用(yong)電(dian)量(liang)(liang)和反向(xiang)用(yong)電(dian)量(liang)(liang)。

2、繼電器控制(僅限預付(fu)費型)

　　2.1 無費關斷(duan)(預付費控制)

　　多用(yong)(yong)(yong)(yong)(yong)戶電(dian)能表可(ke)(ke)設(she)置報(bao)(bao)警電(dian)量(liang)(liang)1和報(bao)(bao)警電(dian)量(liang)(liang)2。當(dang)用(yong)(yong)(yong)(yong)(yong)戶用(yong)(yong)(yong)(yong)(yong)電(dian)時，遞(di)增(zeng)用(yong)(yong)(yong)(yong)(yong)戶總用(yong)(yong)(yong)(yong)(yong)電(dian)量(liang)(liang)，并遞(di)減(jian)用(yong)(yong)(yong)(yong)(yong)戶剩(sheng)余(yu)電(dian)量(liang)(liang)。當(dang)用(yong)(yong)(yong)(yong)(yong)戶剩(sheng)余(yu)電(dian)量(liang)(liang)小于(yu)(yu)報(bao)(bao)警電(dian)量(liang)(liang)1時，LCD顯示“請購電(dian)”，剩(sheng)余(yu)電(dian)量(liang)(liang)小于(yu)(yu)報(bao)(bao)警電(dian)量(liang)(liang)2時，電(dian)能表自動拉閘斷電(dian)，一段時間后可(ke)(ke)恢(hui)復供電(dian)。恢(hui)復時間可(ke)(ke)設(she)為0-255s，值為0不斷電(dian)，若值為255，則斷電(dian)后不恢(hui)復供電(dian)。剩(sheng)余(yu)電(dian)量(liang)(liang)小于(yu)(yu)0后的用(yong)(yong)(yong)(yong)(yong)電(dian)量(liang)(liang)計入透支(zhi)金額，當(dang)透支(zhi)金額大(da)于(yu)(yu)設(she)定(ding)值時，切斷該(gai)用(yong)(yong)(yong)(yong)(yong)戶供電(dian)，只有用(yong)(yong)(yong)(yong)(yong)戶購電(dian)后才可(ke)(ke)恢(hui)復用(yong)(yong)(yong)(yong)(yong)電(dian)。

　　2.2 定時(shi)斷電(dian)(時(shi)控)

　　多(duo)用(yong)(yong)戶(hu)電(dian)能(neng)表(biao)可(ke)對用(yong)(yong)戶(hu)用(yong)(yong)電(dian)進行時(shi)間控制，電(dian)能(neng)表(biao)通過后臺管(guan)(guan)理(li)軟件，設定自動斷電(dian)、上電(dian)時(shi)間，方便(bian)對用(yong)(yong)戶(hu)的用(yong)(yong)電(dian)管(guan)(guan)理(li)。

　　2.3 超(chao)負(fu)荷(he)斷電(負(fu)控)

　　多用(yong)(yong)(yong)戶電(dian)(dian)(dian)能(neng)表(biao)可(ke)設(she)(she)(she)置用(yong)(yong)(yong)戶的(de)z大負(fu)荷(he)功(gong)率(lv)(lv)，當用(yong)(yong)(yong)戶的(de)實際功(gong)率(lv)(lv)大于(yu)設(she)(she)(she)定(ding)(ding)值時，電(dian)(dian)(dian)能(neng)表(biao)自(zi)(zi)動(dong)(dong)切斷(duan)(duan)該(gai)戶供(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)路，功(gong)率(lv)(lv)未(wei)超過(guo)z大負(fu)荷(he)功(gong)率(lv)(lv)設(she)(she)(she)定(ding)(ding)值，并且客(ke)戶有(you)惡(e)性負(fu)載識別需求，電(dian)(dian)(dian)能(neng)表(biao)可(ke)自(zi)(zi)動(dong)(dong)判斷(duan)(duan)，如判斷(duan)(duan)是惡(e)性負(fu)載，則切斷(duan)(duan)該(gai)用(yong)(yong)(yong)戶供(gong)電(dian)(dian)(dian)，一段(duan)時間(jian)后(可(ke)設(she)(she)(she)定(ding)(ding))，可(ke)自(zi)(zi)動(dong)(dong)恢(hui)復(fu)(fu)(fu)供(gong)電(dian)(dian)(dian)，當恢(hui)復(fu)(fu)(fu)次數超過(guo)設(she)(she)(she)定(ding)(ding)值時，不能(neng)自(zi)(zi)動(dong)(dong)恢(hui)復(fu)(fu)(fu)供(gong)電(dian)(dian)(dian)，用(yong)(yong)(yong)戶必須手(shou)動(dong)(dong)清(qing)零恢(hui)復(fu)(fu)(fu)次數方可(ke)供(gong)電(dian)(dian)(dian)。

　　2.4 強(qiang)制斷(duan)電 (強(qiang)控)

　　多用戶電(dian)能表可由(you)后(hou)臺管理(li)系統對(dui)用戶進行強制(zhi)斷電(dian)、送(song)電(dian)控(kong)制(zhi)，使管理(li)中心可以及時地處理(li)突發(fa)事件。

　　注(zhu)意：以上四(si)種控(kong)制中，當(dang)強控(kong)打開時，其(qi)它控(kong)制均(jun)無效(xiao)。
