1、電能計量

　　多用(yong)(yong)戶(hu)電(dian)能(neng)表可計量每(mei)一(yi)用(yong)(yong)戶(hu)總用(yong)(yong)電(dian)量(正(zheng)向+反向)、正(zheng)向用(yong)(yong)電(dian)量和反向用(yong)(yong)電(dian)量。

2、繼電器控制(zhi)(僅限(xian)預付費型)

　　2.1 無費(fei)關斷(預付費(fei)控制)

　　多用(yong)(yong)(yong)戶(hu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能表可(ke)設置(zhi)報警(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)1和報警(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)2。當用(yong)(yong)(yong)戶(hu)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)，遞增(zeng)用(yong)(yong)(yong)戶(hu)總(zong)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)，并遞減用(yong)(yong)(yong)戶(hu)剩(sheng)余電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)。當用(yong)(yong)(yong)戶(hu)剩(sheng)余電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)小于(yu)(yu)報警(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)1時(shi)，LCD顯示(shi)“請購(gou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)”，剩(sheng)余電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)小于(yu)(yu)報警(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)2時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能表自動拉(la)閘(zha)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，一段(duan)時(shi)間后(hou)可(ke)恢(hui)復供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。恢(hui)復時(shi)間可(ke)設為0-255s，值(zhi)為0不斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，若值(zhi)為255，則斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)不恢(hui)復供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。剩(sheng)余電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)小于(yu)(yu)0后(hou)的用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)計入透支金(jin)額，當透支金(jin)額大(da)于(yu)(yu)設定值(zhi)時(shi)，切(qie)斷(duan)該用(yong)(yong)(yong)戶(hu)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，只有(you)用(yong)(yong)(yong)戶(hu)購(gou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)才可(ke)恢(hui)復用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

　　2.2 定時斷(duan)電(時控(kong))

　　多用(yong)戶(hu)電能表可(ke)對用(yong)戶(hu)用(yong)電進行時(shi)間控(kong)制，電能表通(tong)過后臺管理軟件，設定自動斷(duan)電、上電時(shi)間，方便對用(yong)戶(hu)的用(yong)電管理。

　　2.3 超負(fu)荷(he)斷電(負(fu)控)

　　多(duo)用戶(hu)電(dian)(dian)能表可(ke)(ke)設置用戶(hu)的(de)z大(da)負荷(he)功率(lv)，當用戶(hu)的(de)實(shi)際功率(lv)大(da)于(yu)設定(ding)值(zhi)時，電(dian)(dian)能表自動(dong)切斷(duan)該戶(hu)供(gong)電(dian)(dian)電(dian)(dian)路，功率(lv)未超過z大(da)負荷(he)功率(lv)設定(ding)值(zhi)，并(bing)且客(ke)戶(hu)有惡(e)性負載(zai)(zai)識(shi)別需求，電(dian)(dian)能表可(ke)(ke)自動(dong)判斷(duan)，如判斷(duan)是惡(e)性負載(zai)(zai)，則切斷(duan)該用戶(hu)供(gong)電(dian)(dian)，一段時間后(可(ke)(ke)設定(ding))，可(ke)(ke)自動(dong)恢(hui)復供(gong)電(dian)(dian)，當恢(hui)復次(ci)數超過設定(ding)值(zhi)時，不能自動(dong)恢(hui)復供(gong)電(dian)(dian)，用戶(hu)必須手動(dong)清零恢(hui)復次(ci)數方(fang)可(ke)(ke)供(gong)電(dian)(dian)。

　　2.4 強制斷電 (強控(kong))

　　多用(yong)戶(hu)(hu)電能表可由后(hou)臺(tai)管理(li)系統對用(yong)戶(hu)(hu)進行(xing)強制斷電、送(song)電控制，使管理(li)中心可以及時(shi)地(di)處理(li)突發事件(jian)。

　　注意：以(yi)上四(si)種(zhong)控(kong)制中，當強控(kong)打(da)開(kai)時，其(qi)它控(kong)制均無效。
