功能介紹

1 電(dian)能計量

多(duo)用戶電(dian)(dian)能表(biao)可計量每一用戶總用電(dian)(dian)量（正向+反向）、正向用電(dian)(dian)量和反向用電(dian)(dian)量。

2 繼電(dian)器控制（僅限預付費型）

2.1 無(wu)費關斷（預付費控制(zhi)）

多用(yong)(yong)戶(hu)電(dian)(dian)(dian)(dian)(dian)(dian)能表(biao)可(ke)設置報警(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)1和報警(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)2。當(dang)(dang)(dang)用(yong)(yong)戶(hu)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)時，遞增用(yong)(yong)戶(hu)總用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)，并(bing)遞減用(yong)(yong)戶(hu)剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)。當(dang)(dang)(dang)用(yong)(yong)戶(hu)剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)小(xiao)于報警(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)1時，LCD顯示“請(qing)購電(dian)(dian)(dian)(dian)(dian)(dian)”，剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)小(xiao)于報警(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)2時，電(dian)(dian)(dian)(dian)(dian)(dian)能表(biao)自動(dong)拉閘(zha)斷電(dian)(dian)(dian)(dian)(dian)(dian)，一段(duan)時間后(hou)(hou)可(ke)恢(hui)復(fu)供電(dian)(dian)(dian)(dian)(dian)(dian)。恢(hui)復(fu)時間可(ke)設為(wei)0-255s，值為(wei)0不斷電(dian)(dian)(dian)(dian)(dian)(dian)，若值為(wei)255，則斷電(dian)(dian)(dian)(dian)(dian)(dian)后(hou)(hou)不恢(hui)復(fu)供電(dian)(dian)(dian)(dian)(dian)(dian)。剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)小(xiao)于0后(hou)(hou)的(de)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)計入透支金額，當(dang)(dang)(dang)透支金額大于設定值時，切斷該(gai)用(yong)(yong)戶(hu)供電(dian)(dian)(dian)(dian)(dian)(dian)，只有用(yong)(yong)戶(hu)購電(dian)(dian)(dian)(dian)(dian)(dian)后(hou)(hou)才可(ke)恢(hui)復(fu)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)。

2.2 定時斷電(dian)（時控）

多用(yong)(yong)(yong)(yong)戶電能表可對用(yong)(yong)(yong)(yong)戶用(yong)(yong)(yong)(yong)電進(jin)行時間控制，電能表通過(guo)后臺管(guan)理軟件(jian)，設定自動斷電、上電時間，方便對用(yong)(yong)(yong)(yong)戶的用(yong)(yong)(yong)(yong)電管(guan)理。

2.3 超負荷斷電（負控）

多用(yong)(yong)戶(hu)(hu)電能(neng)(neng)表(biao)可(ke)設(she)置用(yong)(yong)戶(hu)(hu)的最(zui)大(da)(da)負(fu)荷功(gong)率，當用(yong)(yong)戶(hu)(hu)的實際功(gong)率大(da)(da)于設(she)定值時，電能(neng)(neng)表(biao)自動(dong)切斷該戶(hu)(hu)供(gong)電電路，功(gong)率未(wei)超過(guo)最(zui)大(da)(da)負(fu)荷功(gong)率設(she)定值，并且客戶(hu)(hu)有惡(e)性(xing)負(fu)載識別需求，電能(neng)(neng)表(biao)可(ke)自動(dong)判斷，如判斷是惡(e)性(xing)負(fu)載，則切斷該用(yong)(yong)戶(hu)(hu)供(gong)電，一(yi)段(duan)時間(jian)后(可(ke)設(she)定)，可(ke)自動(dong)恢(hui)復(fu)供(gong)電，當恢(hui)復(fu)次數(shu)超過(guo)設(she)定值時，不(bu)能(neng)(neng)自動(dong)恢(hui)復(fu)供(gong)電，用(yong)(yong)戶(hu)(hu)必(bi)須手動(dong)清零恢(hui)復(fu)次數(shu)方可(ke)供(gong)電。

2.4 強(qiang)制(zhi)斷(duan)電 (強(qiang)控)

多用戶(hu)電能(neng)表可(ke)(ke)由后臺管理系統對用戶(hu)進(jin)行強制(zhi)斷(duan)電、送電控制(zhi)，使管理中心可(ke)(ke)以及時地處理突發(fa)事(shi)件。

注(zhu)意(yi)：以(yi)上四種控制中(zhong)，當(dang)強控打開時(shi)，其它控制均無效(xiao)。
