　　7.2 繼電器控(kong)制(僅限預(yu)付費型)

　　7.2.1 無費關斷(duan)(預付費控制)

　　多用(yong)戶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)可設(she)置(zhi)報警(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)1和報警(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)2。當用(yong)戶用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時，遞增(zeng)用(yong)戶總用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)，并(bing)遞減用(yong)戶剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)。當用(yong)戶剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)小(xiao)于報警(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)1時，LCD顯示“請購電(dian)(dian)(dian)(dian)(dian)(dian)(dian)”，剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)小(xiao)于報警(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)2時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)表(biao)自動拉閘斷(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，一段時間后(hou)可恢復(fu)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。恢復(fu)時間可設(she)為0-255s，值為0不斷(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，若值為255，則斷(duan)(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)不恢復(fu)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)小(xiao)于0后(hou)的用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)計入透支(zhi)(zhi)金(jin)額(e)，當透支(zhi)(zhi)金(jin)額(e)大于設(she)定值時，切斷(duan)(duan)該(gai)用(yong)戶供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，只有用(yong)戶購電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)才可恢復(fu)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

　　7.2.2 定時斷(duan)電(時控(kong))

　　多(duo)用(yong)戶電(dian)(dian)能表可對(dui)用(yong)戶用(yong)電(dian)(dian)進行時間(jian)控制，電(dian)(dian)能表通過后臺管理軟件，設定自動斷電(dian)(dian)、上(shang)電(dian)(dian)時間(jian)，方便對(dui)用(yong)戶的用(yong)電(dian)(dian)管理。

　　7.2.3 超負荷斷電(負控)

　　多用戶(hu)電(dian)(dian)(dian)(dian)能(neng)表可(ke)設置用戶(hu)的(de)(de)z大(da)負荷(he)(he)功率(lv)，當用戶(hu)的(de)(de)實際(ji)功率(lv)大(da)于設定(ding)(ding)值時(shi)，電(dian)(dian)(dian)(dian)能(neng)表自動(dong)切(qie)斷(duan)該(gai)戶(hu)供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)路(lu)，功率(lv)未超過(guo)z大(da)負荷(he)(he)功率(lv)設定(ding)(ding)值，并且(qie)客戶(hu)有惡性負載識(shi)別需求，電(dian)(dian)(dian)(dian)能(neng)表可(ke)自動(dong)判斷(duan)，如判斷(duan)是(shi)惡性負載，則切(qie)斷(duan)該(gai)用戶(hu)供電(dian)(dian)(dian)(dian)，一段時(shi)間后(可(ke)設定(ding)(ding))，可(ke)自動(dong)恢(hui)(hui)復供電(dian)(dian)(dian)(dian)，當恢(hui)(hui)復次數(shu)超過(guo)設定(ding)(ding)值時(shi)，不能(neng)自動(dong)恢(hui)(hui)復供電(dian)(dian)(dian)(dian)，用戶(hu)必須手(shou)動(dong)清(qing)零恢(hui)(hui)復次數(shu)方可(ke)供電(dian)(dian)(dian)(dian)。

　　7.2.4 強制(zhi)斷電 (強控)

　　多用戶電能(neng)表(biao)可由后臺管理(li)系統(tong)對用戶進行強制斷電、送電控制，使管理(li)中(zhong)心可以及(ji)時地(di)處理(li)突發事(shi)件。

　　注(zhu)意：以上四種控制中，當強控打開時，其它控制均無效。
