電(dian)能表正常(chang)工作后出(chu)現自動(dong)斷電(dian)現象主(zhu)要有以(yi)下(xia)五(wu)種(zhong)功能決定。

1、?拉閘報(bao)警(jing)斷電

拉閘(zha)報警斷(duan)電(dian)的目的主要是提醒用戶及時(shi)(shi)買(mai)電(dian)，例如拉閘(zha)報警斷(duan)電(dian)值設置為(wei)10度(du)(du)，當電(dian)能(neng)表(biao)顯示用戶購(gou)電(dian)量剩余(yu)為(wei)10度(du)(du)時(shi)(shi)，該(gai)戶的繼電(dian)器自(zi)動斷(duan)電(dian)，提醒用戶及時(shi)(shi)買(mai)電(dian)，這(zhe)時(shi)(shi)該(gai)戶的戶號閃爍。拉閘(zha)報(bao)警斷電(dian)值(zhi)可(ke)以(yi)通過計算機聯網系統來(lai)設置，也(ye)可(ke)以(yi)由(you)IC卡(ka)售(shou)電(dian)管理系統來(lai)設定。

當(dang)出現拉閘報警斷電(dian)(dian)(dian)時，可采取三種方(fang)法使電(dian)(dian)(dian)能表正常供電(dian)(dian)(dian)：

（1） 在電(dian)能表顯示到該(gai)戶時(shi)按(an)一下(xia)(xia)電(dian)表下(xia)(xia)邊的上電(dian)按(an)鈕(niu)，這時(shi)該(gai)戶即(ji)可正(zheng)常用電(dian)，該(gai)戶的戶號也不再閃爍。

（2） 通過IC卡(ka)售電的用(yong)戶(hu)可把(ba)該(gai)戶(hu)的IC卡(ka)在射頻卡(ka)讀(du)卡(ka)器上刷(shua)卡(ka)，這時該(gai)戶(hu)即可正常用(yong)電，該(gai)戶(hu)的戶(hu)號也不再閃爍。

（3） 通(tong)過計算機(ji)聯(lian)網售電(dian)的用戶(hu)可通(tong)過計算機(ji)軟件(jian)系統(tong)對(dui)該用戶(hu)進行上電(dian)，這時(shi)該戶(hu)即(ji)可正常用電(dian)，該戶(hu)的戶(hu)號也不再閃爍。

當出現拉(la)閘報警斷電后，用(yong)戶(hu)應盡快到售電中心購(gou)買電量輸(shu)入電能表，否則，用(yong)戶(hu)用(yong)完拉(la)閘報警斷電值后，電能表將進行余額為零斷電。

2、?余額為零斷(duan)電

余額為(wei)零斷電(dian)是電(dian)能表顯示(shi)用戶購電(dian)量為(wei)0度時，該戶的繼電(dian)器自動斷電(dian)，提醒用戶必(bi)須買電(dian)，這時該戶的戶號(hao)閃爍(shuo)，用電(dian)量顯(xian)示為(wei)—0000.0。此時(shi)用戶應盡快到售電(dian)中心購買(mai)電(dian)量輸入電(dian)能表。

3、 惡性負載斷電

當用(yong)戶使用(yong)電熱(re)爐、電熱(re)杯、電暖氣、熱(re)得快等“惡性負載(zai)”時(shi)，電能(neng)(neng)表可(ke)自(zi)動(dong)識別并斷電，當此類(lei)負載(zai)去掉后自(zi)動(dong)上電。（此功能(neng)(neng)適用(yong)于公(gong)寓(yu)用(yong)電管理，須(xu)定制(zhi)）

4、 超負荷斷電

電(dian)(dian)(dian)能(neng)(neng)(neng)表(biao)可(ke)設定用(yong)(yong)(yong)戶(hu)的(de)負(fu)荷電(dian)(dian)(dian)流(liu)，當用(yong)(yong)(yong)戶(hu)的(de)用(yong)(yong)(yong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)超(chao)過(guo)限(xian)額電(dian)(dian)(dian)流(liu)時，電(dian)(dian)(dian)能(neng)(neng)(neng)表(biao)自(zi)動(dong)切(qie)斷該供電(dian)(dian)(dian)電(dian)(dian)(dian)路，待5分鐘后自(zi)動(dong)上(shang)電(dian)(dian)(dian)，若用(yong)(yong)(yong)戶(hu)的(de)用(yong)(yong)(yong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)仍超(chao)過(guo)限(xian)額電(dian)(dian)(dian)流(liu)，電(dian)(dian)(dian)能(neng)(neng)(neng)表(biao)將(jiang)再(zai)次斷電(dian)(dian)(dian)。

5、定時控制斷電

電(dian)能表(biao)可對用(yong)戶(hu)用(yong)電(dian)進(jin)行時(shi)間(jian)控制，電(dian)能表(biao)通過(guo)IC卡(ka)售電(dian)系統(tong)或計算機聯(lian)網系統(tong)，設定自(zi)動斷(duan)電(dian)、自(zi)動上電(dian)時(shi)間(jian)，方便對用(yong)戶(hu)的用(yong)電(dian)管理。（此功(gong)能適用(yong)于公寓管理，須定制）
