功能介紹

1 電能(neng)計量

多用(yong)(yong)戶(hu)電能(neng)表可計(ji)量(liang)每(mei)一用(yong)(yong)戶(hu)總(zong)用(yong)(yong)電量(liang)（正(zheng)向+反(fan)向）、正(zheng)向用(yong)(yong)電量(liang)和(he)反(fan)向用(yong)(yong)電量(liang)。

2 繼電器控(kong)制（僅限預付費型(xing)）

2.1 無(wu)費(fei)關(guan)斷（預付費(fei)控制）

多用戶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)表可設(she)置報警電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)1和報警電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)2。當用戶用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)，遞增用戶總用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)，并(bing)遞減用戶剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)。當用戶剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)小(xiao)于報警電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)1時(shi)，LCD顯示(shi)“請(qing)購電(dian)(dian)(dian)(dian)(dian)(dian)(dian)”，剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)小(xiao)于報警電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)2時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)表自動拉閘斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，一段(duan)時(shi)間(jian)(jian)后可恢(hui)復(fu)(fu)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。恢(hui)復(fu)(fu)時(shi)間(jian)(jian)可設(she)為0-255s，值(zhi)為0不斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，若(ruo)值(zhi)為255，則(ze)斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后不恢(hui)復(fu)(fu)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。剩余(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)小(xiao)于0后的用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)(liang)計入透支金額，當透支金額大于設(she)定(ding)值(zhi)時(shi)，切(qie)斷(duan)該用戶供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，只(zhi)有用戶購電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后才可恢(hui)復(fu)(fu)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

2.2 定(ding)時斷電（時控(kong)）

多用(yong)戶電能表可對用(yong)戶用(yong)電進行(xing)時間控制，電能表通(tong)過后臺(tai)管理(li)(li)軟件，設定自動(dong)斷電、上電時間，方便(bian)對用(yong)戶的用(yong)電管理(li)(li)。

2.3 超負(fu)荷(he)斷電（負(fu)控）

多用(yong)戶(hu)(hu)電(dian)(dian)能表(biao)(biao)可設置(zhi)用(yong)戶(hu)(hu)的最(zui)大負荷(he)功(gong)(gong)率(lv)，當用(yong)戶(hu)(hu)的實際(ji)功(gong)(gong)率(lv)大于設定值(zhi)時(shi)(shi)，電(dian)(dian)能表(biao)(biao)自(zi)動切斷該戶(hu)(hu)供(gong)電(dian)(dian)電(dian)(dian)路，功(gong)(gong)率(lv)未超(chao)過最(zui)大負荷(he)功(gong)(gong)率(lv)設定值(zhi)，并且客戶(hu)(hu)有惡(e)性(xing)負載識別(bie)需求(qiu)，電(dian)(dian)能表(biao)(biao)可自(zi)動判斷，如判斷是惡(e)性(xing)負載，則切斷該用(yong)戶(hu)(hu)供(gong)電(dian)(dian)，一段時(shi)(shi)間(jian)后(可設定)，可自(zi)動恢復(fu)供(gong)電(dian)(dian)，當恢復(fu)次數超(chao)過設定值(zhi)時(shi)(shi)，不能自(zi)動恢復(fu)供(gong)電(dian)(dian)，用(yong)戶(hu)(hu)必須手動清零恢復(fu)次數方(fang)可供(gong)電(dian)(dian)。

2.4 強制斷電 (強控)

多用戶電(dian)能表可(ke)由(you)后臺管(guan)理(li)系統對用戶進行強制(zhi)斷電(dian)、送電(dian)控制(zhi)，使管(guan)理(li)中心可(ke)以及時(shi)地處理(li)突發(fa)事件。

注意：以(yi)上四(si)種(zhong)控(kong)制(zhi)中，當(dang)強(qiang)控(kong)打(da)開(kai)時(shi)，其(qi)它控(kong)制(zhi)均無效。
