主(zhu)要特點:應用(yong)計算機管(guan)理,先購電(dian)(dian)(dian)后(hou)用(yong)電(dian)(dian)(dian);在額(e)定(ding)電(dian)(dian)(dian)流(liu)范圍(wei)內能限制(zhi)使用(yong)功率(由供電(dian)(dian)(dian)部(bu)門限定(ding));一表一卡(ka),專(zhuan)卡(ka)專(zhuan)用(yong),失卡(ka)不(bu)失電(dian)(dian)(dian),補卡(ka)再(zai)用(yong);電(dian)(dian)(dian)卡(ka)能雙(shuang)向傳遞(di)數據,能自(zi)動斷電(dian)(dian)(dian)告警用(yong)戶購電(dian)(dian)(dian);電(dian)(dian)(dian)量為零時,自(zi)動拉閘(zha)斷電(dian)(dian)(dian);并具有(you)一定(ding)的(de)防竊(qie)電(dian)(dian)(dian)軟件設計等。
二、工作(zuo)原理
1、工作原(yuan)理圖
電(dian)(dian)(dian)(dian)能(neng)表由(you)分壓器(qi)取得電(dian)(dian)(dian)(dian)壓采樣信號(hao),分流(liu)器(qi)取得電(dian)(dian)(dian)(dian)流(liu)采樣信號(hao),經乘(cheng)法器(qi)得到電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)流(liu)乘(cheng)積信號(hao),再(zai)經頻(pin)率變換產(chan)生一(yi)個(ge)頻(pin)率與電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)流(liu)乘(cheng)積成正比(bi)的計(ji)數(shu)脈沖,通(tong)過分頻(pin),驅動步進電(dian)(dian)(dian)(dian)機(ji)計(ji)量電(dian)(dian)(dian)(dian)度(du)。
2、數據處理
電能計(ji)(ji)量脈經光電耦合器(qi)(qi)(qi)送CPU處理,運算(suan)后存儲于存儲器(qi)(qi)(qi)中。由(you)計(ji)(ji)算(suan)機管理信息系(xi)統,通過IC卡讀(du)寫(xie)器(qi)(qi)(qi),寫(xie)入一定電量和(he)監(jian)控要求(qiu)的IC卡輸入表內微處理器(qi)(qi)(qi)系(xi)統,經CPU運算(suan)后,提(ti)供顯示、報警狀態信號。

四、安裝與使用
1、電表在(zai)出廠時(shi)經檢驗(yan)合格,并(bing)加(jia)封鉛印,可安(an)(an)裝使用,如(ru)無鉛封或貯存過(guo)久,應請(qing)有關部門重新校驗(yan)加(jia)封,方(fang)可安(an)(an)裝使用。
2、電表(biao)(biao)應(ying)安(an)裝在(zai)干燥通(tong)風的地方,安(an)裝電表(biao)(biao)的底板應(ying)固(gu)定在(zai)堅固(gu)耐火(huo),不(bu)易振動(dong)的墻上(shang),電表(biao)(biao)高度約1.8m左右。
3、按(an)圖(tu)一、圖(tu)二安(an)裝和接線,擰緊(jin)接線螺釘,并緊(jin)固端(duan)鈕盒內連接板。
4、經互感器(qi)接入式(shi)電表(biao)其示數(shu)須乘(cheng)以變比后,才(cai)是實際電能(neng)數(shu)。
5、一(yi)表一(yi)卡(ka):用戶持有的IC卡(ka)不能互換,遺失時(shi)應到供電部(bu)門(售(shou)電處)補購一(yi)張。
6、購(gou)電(dian)準(zhun)備:購(gou)電(dian)前,用戶(hu)須將IC卡(ka)插(cha)入卡(ka)座一次,便于將表內數(shu)據送回計算機數(shu)據庫。
7、購電(dian)方式:售電(dian)時,將(jiang)IC卡(ka)插入IC卡(ka)讀寫(xie)器,同(tong)時操(cao)作計算(suan)機(ji),將(jiang)用(yong)戶編號、預購電(dian)量(liang)(liang)、報警電(dian)量(liang)(liang)、限(xian)容(rong)方式及(ji)限(xian)容(rong)功率(lv)等加密寫(xie)入IC卡(ka)。
8、電(dian)(dian)卡(ka)使用:將購(gou)電(dian)(dian)卡(ka)插(cha)入卡(ka)座內,如是(shi)有效購(gou)電(dian)(dian)卡(ka),則電(dian)(dian)表(biao)自動將數(shu)(shu)據讀(du)入表(biao)內,LCD(LED)表(biao)顯(xian)示屏依次顯(xian)示:購(gou)電(dian)(dian)量(liang)(liang)(P0== XXXX)、總購(gou)電(dian)(dian)量(liang)(liang)(P=XX XXXX)、購(gou)電(dian)(dian)次數(shu)(shu)(PC== XXXX)、報警電(dian)(dian)量(liang)(liang)(P1==XXXX)、賒欠(qian)限量(liang)(liang)(P2== XXXX)、限容功率(F0X= XX:XX)。拔卡(ka)請妥善保存。
9、運行(xing)顯示:電表運行(xing)過程(cheng)中,輪流顯示表內剩(sheng)余電量(liang)、總用電量(liang)。
10、超(chao)容(rong)(rong)報警(jing):電(dian)(dian)(dian)表(biao)運行(xing)過(guo)程中,如果(guo)“報警(jing)指示(shi)(shi)燈”快速閃爍顯示(shi)(shi),則(ze)警(jing)告用戶已超(chao)容(rong)(rong)用電(dian)(dian)(dian)。如該電(dian)(dian)(dian)表(biao)被設(she)置(zhi)為超(chao)容(rong)(rong)斷電(dian)(dian)(dian)限容(rong)(rong)方(fang)式,則(ze)超(chao)容(rong)(rong)用電(dian)(dian)(dian)30秒后,將拉閘3分鐘,并倒計時(shi)顯(xian)示(180秒(miao))恢復供(gong)(gong)電時間;如用戶插卡響應可立(li)即恢復供(gong)(gong)電。
11、 囤積限量(liang)(liang):如果購電(dian)量(liang)(liang)+剩余(yu)電(dian)量(liang)(liang)>囤積限量(liang)(liang)(10000kWh),則(ze)購電(dian)量(liang)(liang)不讀(du)入,顯示器顯示“剩余(yu)限量(liang)(liang)”提示,卡內(nei)電(dian)量(liang)(liang)仍(reng)有效。
12、 預警提(ti)醒:當(dang)表(biao)內剩余(yu)電(dian)量小(xiao)于“報(bao)警電(dian)量”的(de)2倍(bei)時(shi)(shi),“報(bao)警指示(shi)燈”將閃(shan)(shan)爍(shuo)(間(jian)隔(ge)為1秒(miao))顯示(shi)提(ti)醒用戶購電(dian),此時(shi)(shi)如用戶插卡響應(ying),“報(bao)警指示(shi)燈”閃(shan)(shan)爍(shuo)間(jian)隔(ge)變為2秒(miao),可(ke)以避免斷電(dian)警告。
13、 斷電警(jing)告:如在預(yu)警(jing)提醒時用(yong)戶未(wei)插(cha)卡(ka)(ka)響應,且設(she)置(zhi)超容報(bao)警(jing),則當剩(sheng)余電量(liang)為(wei)用(yong)戶約定的報(bao)警(jing)電量(liang)(或本(ben)(ben)次(ci)購電量(liang)的10%)時,電表(biao)(biao)拉(la)閘斷電警(jing)告,顯示“拉(la)閘”提示符,此時將(jiang)IC卡(ka)(ka)在卡(ka)(ka)座上插(cha)一(yi)次(ci)即恢復供電。如果拉(la)閘后找不到本(ben)(ben)表(biao)(biao)IC卡(ka)(ka),可(ke)借用(yong)鄰(lin)居(ju)IC卡(ka)(ka)插(cha)入,以恢復供電。
14、 購(gou)電提醒:當表內剩余電量小于(yu)“報(bao)警電量”時,“報(bao)警指示燈”將(jiang)常(chang)亮(liang)提醒。
15、 故障申報:剩余電量顯(xian)示為零或負值時,顯(xian)示“拉閘”提示符,如電表仍繼續運行,用戶應立即(ji)購電,并主動向(xiang)供電部門反映情(qing)況。

五、運輸與(yu)貯(zhu)存
1、表在運輸(shu)和拆(chai)封時(shi)不(bu)應受到劇烈沖擊。
2、 能表(biao)應保存在原包裝內,環境溫(wen)度(du)(du)為-25℃ ~ +55℃,相對濕度(du)(du)不(bu)超(chao)過(guo)(guo)85%,空氣中無腐蝕性氣體的(de)(de)環境中。電(dian)能表(biao)在貨架上(shang)貯存時,整箱(xiang)疊放高(gao)度(du)(du)不(bu)超(chao)過(guo)(guo)5箱(xiang),拆箱(xiang)后(hou)單只包裝的(de)(de)電(dian)能表(biao)疊放高(gao)度(du)(du)不(bu)超(chao)過(guo)(guo)10只。
