功能介紹

1 電能(neng)計量

多用戶電(dian)能表可(ke)計(ji)量每一用戶總用電(dian)量（正(zheng)向+反向）、正(zheng)向用電(dian)量和(he)反向用電(dian)量。

2 繼電器控制（僅(jin)限預付費型(xing)）

2.1 無費(fei)關斷（預付費(fei)控制）

多(duo)用(yong)(yong)(yong)(yong)(yong)(yong)戶(hu)(hu)電(dian)(dian)(dian)(dian)能(neng)(neng)表可設(she)置(zhi)報警電(dian)(dian)(dian)(dian)量1和報警電(dian)(dian)(dian)(dian)量2。當用(yong)(yong)(yong)(yong)(yong)(yong)戶(hu)(hu)用(yong)(yong)(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)，遞增用(yong)(yong)(yong)(yong)(yong)(yong)戶(hu)(hu)總用(yong)(yong)(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)量，并遞減用(yong)(yong)(yong)(yong)(yong)(yong)戶(hu)(hu)剩(sheng)余電(dian)(dian)(dian)(dian)量。當用(yong)(yong)(yong)(yong)(yong)(yong)戶(hu)(hu)剩(sheng)余電(dian)(dian)(dian)(dian)量小于(yu)(yu)報警電(dian)(dian)(dian)(dian)量1時(shi)(shi)(shi)，LCD顯示“請購電(dian)(dian)(dian)(dian)”，剩(sheng)余電(dian)(dian)(dian)(dian)量小于(yu)(yu)報警電(dian)(dian)(dian)(dian)量2時(shi)(shi)(shi)，電(dian)(dian)(dian)(dian)能(neng)(neng)表自(zi)動拉閘斷電(dian)(dian)(dian)(dian)，一段時(shi)(shi)(shi)間后可恢復供電(dian)(dian)(dian)(dian)。恢復時(shi)(shi)(shi)間可設(she)為(wei)0-255s，值為(wei)0不斷電(dian)(dian)(dian)(dian)，若值為(wei)255，則斷電(dian)(dian)(dian)(dian)后不恢復供電(dian)(dian)(dian)(dian)。剩(sheng)余電(dian)(dian)(dian)(dian)量小于(yu)(yu)0后的用(yong)(yong)(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)量計(ji)入透支金額，當透支金額大于(yu)(yu)設(she)定值時(shi)(shi)(shi)，切斷該用(yong)(yong)(yong)(yong)(yong)(yong)戶(hu)(hu)供電(dian)(dian)(dian)(dian)，只(zhi)有用(yong)(yong)(yong)(yong)(yong)(yong)戶(hu)(hu)購電(dian)(dian)(dian)(dian)后才可恢復用(yong)(yong)(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)。

2.2 定時斷電（時控(kong)）

多用(yong)戶電(dian)能(neng)表可對(dui)用(yong)戶用(yong)電(dian)進(jin)行(xing)時(shi)間控制，電(dian)能(neng)表通(tong)過后臺管(guan)理(li)軟件，設定(ding)自動斷電(dian)、上電(dian)時(shi)間，方便(bian)對(dui)用(yong)戶的(de)用(yong)電(dian)管(guan)理(li)。

2.3 超負(fu)荷斷(duan)電（負(fu)控(kong)）

多用(yong)戶(hu)(hu)電能(neng)表(biao)可(ke)(ke)設置用(yong)戶(hu)(hu)的(de)最大負(fu)荷功率(lv)(lv)，當用(yong)戶(hu)(hu)的(de)實(shi)際(ji)功率(lv)(lv)大于設定值(zhi)(zhi)時，電能(neng)表(biao)自(zi)動(dong)切(qie)(qie)斷該戶(hu)(hu)供(gong)電電路，功率(lv)(lv)未(wei)超(chao)過最大負(fu)荷功率(lv)(lv)設定值(zhi)(zhi)，并(bing)且客戶(hu)(hu)有惡性(xing)負(fu)載識別需求，電能(neng)表(biao)可(ke)(ke)自(zi)動(dong)判斷，如判斷是惡性(xing)負(fu)載，則切(qie)(qie)斷該用(yong)戶(hu)(hu)供(gong)電，一段時間后(可(ke)(ke)設定)，可(ke)(ke)自(zi)動(dong)恢(hui)復(fu)供(gong)電，當恢(hui)復(fu)次(ci)數超(chao)過設定值(zhi)(zhi)時，不能(neng)自(zi)動(dong)恢(hui)復(fu)供(gong)電，用(yong)戶(hu)(hu)必須手動(dong)清零恢(hui)復(fu)次(ci)數方可(ke)(ke)供(gong)電。

2.4 強制斷電 (強控(kong))

多(duo)用(yong)戶(hu)電能表可由后臺(tai)管理(li)系(xi)統對用(yong)戶(hu)進行(xing)強制斷電、送電控(kong)制，使(shi)管理(li)中(zhong)心可以及時(shi)地(di)處理(li)突發(fa)事件。

注意(yi)：以上四種控制中，當強(qiang)控打(da)開時(shi)，其它(ta)控制均無效。
