功(gong)能介紹

1 電能計量

多用戶電能表可計(ji)量(liang)每一用戶總用電量(liang)（正(zheng)向(xiang)(xiang)+反(fan)向(xiang)(xiang)）、正(zheng)向(xiang)(xiang)用電量(liang)和反(fan)向(xiang)(xiang)用電量(liang)。

2 繼電器控制（僅限預付費型）

2.1 無費(fei)關斷（預付費(fei)控制）

多用(yong)(yong)(yong)(yong)戶(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)表可設(she)置報(bao)警(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)1和報(bao)警(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)2。當(dang)用(yong)(yong)(yong)(yong)戶(hu)(hu)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)，遞增(zeng)用(yong)(yong)(yong)(yong)戶(hu)(hu)總用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)，并遞減用(yong)(yong)(yong)(yong)戶(hu)(hu)剩(sheng)余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)。當(dang)用(yong)(yong)(yong)(yong)戶(hu)(hu)剩(sheng)余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)小于(yu)報(bao)警(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)1時(shi)(shi)(shi)，LCD顯示“請購電(dian)(dian)(dian)(dian)(dian)(dian)”，剩(sheng)余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)小于(yu)報(bao)警(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)2時(shi)(shi)(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)表自動拉(la)閘斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)，一段時(shi)(shi)(shi)間(jian)(jian)后可恢(hui)復供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)。恢(hui)復時(shi)(shi)(shi)間(jian)(jian)可設(she)為(wei)(wei)0-255s，值為(wei)(wei)0不(bu)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)，若值為(wei)(wei)255，則斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)后不(bu)恢(hui)復供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)。剩(sheng)余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)小于(yu)0后的用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)計入透支金(jin)額(e)，當(dang)透支金(jin)額(e)大于(yu)設(she)定值時(shi)(shi)(shi)，切斷(duan)該用(yong)(yong)(yong)(yong)戶(hu)(hu)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)，只有(you)用(yong)(yong)(yong)(yong)戶(hu)(hu)購電(dian)(dian)(dian)(dian)(dian)(dian)后才(cai)可恢(hui)復用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)。

2.2 定(ding)時斷電（時控）

多(duo)用(yong)(yong)戶電(dian)(dian)(dian)能(neng)表可對用(yong)(yong)戶用(yong)(yong)電(dian)(dian)(dian)進(jin)行(xing)時(shi)間(jian)控(kong)制，電(dian)(dian)(dian)能(neng)表通(tong)過后臺管(guan)理軟(ruan)件，設定自動斷電(dian)(dian)(dian)、上(shang)電(dian)(dian)(dian)時(shi)間(jian)，方便對用(yong)(yong)戶的用(yong)(yong)電(dian)(dian)(dian)管(guan)理。

2.3 超負荷斷(duan)電（負控）

多用(yong)(yong)戶(hu)(hu)電(dian)(dian)能表(biao)可設(she)置用(yong)(yong)戶(hu)(hu)的最(zui)大(da)負荷功率(lv)(lv)，當用(yong)(yong)戶(hu)(hu)的實際功率(lv)(lv)大(da)于設(she)定(ding)值時，電(dian)(dian)能表(biao)自動(dong)切斷(duan)該(gai)戶(hu)(hu)供(gong)(gong)電(dian)(dian)電(dian)(dian)路，功率(lv)(lv)未超過(guo)最(zui)大(da)負荷功率(lv)(lv)設(she)定(ding)值，并且(qie)客(ke)戶(hu)(hu)有惡性負載識別需求，電(dian)(dian)能表(biao)可自動(dong)判(pan)斷(duan)，如判(pan)斷(duan)是(shi)惡性負載，則切斷(duan)該(gai)用(yong)(yong)戶(hu)(hu)供(gong)(gong)電(dian)(dian)，一段時間后(可設(she)定(ding))，可自動(dong)恢(hui)復(fu)供(gong)(gong)電(dian)(dian)，當恢(hui)復(fu)次(ci)數超過(guo)設(she)定(ding)值時，不能自動(dong)恢(hui)復(fu)供(gong)(gong)電(dian)(dian)，用(yong)(yong)戶(hu)(hu)必(bi)須手動(dong)清零恢(hui)復(fu)次(ci)數方可供(gong)(gong)電(dian)(dian)。

2.4 強(qiang)制斷電 (強(qiang)控(kong))

多用(yong)戶電(dian)能(neng)表可(ke)(ke)由(you)后臺管理(li)系統(tong)對用(yong)戶進行(xing)強制(zhi)斷(duan)電(dian)、送電(dian)控制(zhi)，使管理(li)中心可(ke)(ke)以(yi)及時地處理(li)突發(fa)事(shi)件。

注意：以(yi)上(shang)四種控制中，當(dang)強控打開時，其它控制均(jun)無效。
