WL-J型(xing)多用戶預付(fu)費智能電能表(biao)(Jx型(xing)預付(fu)費控(kong)制型(xing)電能表(biao) 復費率電能表(biao)) 〉〉〉
技術特點
◆電(dian)表(biao)采用先進的計(ji)量和控制芯片(pian)(工業級),模塊化結構設計(ji),抗干擾能力(li)強。
◆表箱體積小(xiao),內部走線規則(ze)、整(zheng)齊(qi),符(fu)合配(pei)電(dian)要求,安裝、維(wei)護、升級方便。
◆電(dian)(dian)(dian)(dian)表(biao)通訊電(dian)(dian)(dian)(dian)路(lu)采(cai)用(yong)防雷(lei)電(dian)(dian)(dian)(dian)路(lu),信(xin)號采(cai)用(yong)光電(dian)(dian)(dian)(dian)隔離,通訊電(dian)(dian)(dian)(dian)路(lu)與電(dian)(dian)(dian)(dian)表(biao)其它電(dian)(dian)(dian)(dian)路(lu)進行分離處理,可(ke)很(hen)大程(cheng)度減輕雷(lei)擊對電(dian)(dian)(dian)(dian)表(biao)的傷害(hai)。
◆電能信號采集模塊接口采用電腦專用接口,經(jing)過特殊處理,信號傳輸可靠。
◆計量電路與(yu)通(tong)訊、顯(xian)示(shi)電路采用雙(shuang)CPU結構(gou),一個CPU主管(guan)計量,一個CPU主管(guan)通(tong)訊、顯(xian)示(shi)和指示(shi),通(tong)訊時不影響計量。
◆內部強電(dian)(dian)與弱(ruo)電(dian)(dian)間采用(yong)鍍(du)鋅屏蔽(bi)板(ban)隔離(li),可減輕強電(dian)(dian)對弱(ruo)電(dian)(dian)信號的干(gan)擾。
◆內部電源三相(xiang)(xiang)供(gong)電,電源缺相(xiang)(xiang),電表照常工作(zuo);
◆電表進線(xian)(xian)端(duan)采用專用接線(xian)(xian)端(duan)子,電流承載能(neng)力強,便于現場(chang)施工。
◆數(shu)(shu)據安全:電表各(ge)種數(shu)(shu)據參數(shu)(shu)采用(yong)加密算法,保證數(shu)(shu)據安全。
◆可(ke)同時(shi)計量與檢測36戶(hu)(39戶(hu))單相或12戶(hu)(13戶(hu))三相及36戶(hu)(39戶(hu))以(yi)下(xia)單三相任意組(zu)合。
◆具有電源缺相指示功能;
功能描述
◆預付(fu)費(fei)(fei)(倒計(ji)數)功能;用戶須(xu)先購電(dian)后用電(dian),欠費(fei)(fei)斷電(dian),繳費(fei)(fei)方(fang)式多樣(yang);
◆過載保護(hu)(限(xian)流)功能:當用(yong)戶負載超過允用(yong)負載時,該用(yong)戶自動斷電保護(hu)。
◆斷(duan)(duan)電自動(dong)恢復功能:用(yong)戶(hu)過(guo)載(zai)斷(duan)(duan)電保護后,在規定的(de)斷(duan)(duan)電次數內,用(yong)戶(hu)使用(yong)的(de)功率降至允許使用(yong)范圍內,系統可以自動(dong)恢復供電。
◆允許透(tou)支電(dian)(dian)量功能(neng),根據用戶信譽不同(tong)可設置相應的允用透(tou)支電(dian)(dian)量,超過設置參數后欠費斷電(dian)(dian)。
◆設置(zhi)階(jie)梯電(dian)量(liang)及階(jie)梯單(dan)(dan)價(jia)(jia)功能:可將每月用(yong)電(dian)量(liang)劃分為多個階(jie)段(至多4個),對應(ying)設置(zhi)相(xiang)應(ying)單(dan)(dan)價(jia)(jia);用(yong)電(dian)量(liang)越(yue)大,單(dan)(dan)價(jia)(jia)越(yue)高,引導用(yong)戶節約(yue)用(yong)電(dian)。
◆可設四種(zhong)費率單價,實行(xing)尖、峰、平、谷(gu)時(shi)段用(yong)電(dian)計費。
◆用(yong)電記(ji)錄(lu)保(bao)存功(gong)能,能夠(gou)保(bao)存連續3個(ge)月(yue)(yue)的(de)用(yong)戶用(yong)電歷史記(ji)錄(lu),月(yue)(yue)結時(shi)(shi)間可以設(she)置(1日—28日);月(yue)(yue)結內容包括:用(yong)電時(shi)(shi)間范(fan)圍、階段累計用(yong)電量(liang)、各階段執行的(de)階梯電量(liang)及電價設(she)定值、各階段的(de)使(shi)用(yong)電費。
