單相(xiang)電子式預付費電能表是(shi)我公(gong)司采用(yong)(yong)的(de)微電(dian)(dian)(dian)子技(ji)術，以(yi)電(dian)(dian)(dian)子IC卡為購電(dian)(dian)(dian)媒介并輔以(yi)電(dian)(dian)(dian)費收繳(jiao)微機管(guan)理(li)自動化(hua)軟(ruan)硬件(jian)技(ji)術，而研制開(kai)發(fa)的(de)新型電(dian)(dian)(dian)度表。該表具(ju)有電(dian)(dian)(dian)能(neng)計(ji)量(liang)，負荷控制，用(yong)(yong)電(dian)(dian)(dian)信息的(de)管(guan)理(li)等多種功(gong)能(neng)，同時實現先購電(dian)(dian)(dian)后用(yong)(yong)電(dian)(dian)(dian)的(de)用(yong)(yong)電(dian)(dian)(dian)管(guan)理(li)制度，是(shi)改革用(yong)(yong)電(dian)(dian)(dian)體制，實現電(dian)(dian)(dian)能(neng)商品化(hua)，解決電(dian)(dian)(dian)力用(yong)(yong)電(dian)(dian)(dian)收費難(nan)及調節電(dian)(dian)(dian)網負荷的(de)理(li)想產品。其技(ji)術性能(neng)完全符合GB/T17215-2002標準和(he)GB/T 18460.3-2001《預付費電(dian)(dian)(dian)度表》的(de)要求(qiu)，適用(yong)(yong)于計(ji)量(liang)額定頻(pin)率(lv)為50Hz或60Hz單(dan)相交(jiao)流有功(gong)電(dian)(dian)(dian)能(neng)。

單相電子式預付費電能表功能特點

主(zhu)要功能特點

準確度(du)高：選(xuan)用(yong)(yong)進口專用(yong)(yong)計量芯片，誤差穩(wen)定，線性好，在低負載時精度(du)高，長期使(shi)用(yong)(yong)無須調校(xiao)。

穩定可靠：抗干擾性和過載能力強，選用磁保繼電器，通斷電有效(xiao)控制。

長(chang)(chang)壽命：運用(yong)SMT先(xian)進工藝制造，主要元(yuan)器(qi)件選用(yong)長(chang)(chang)壽命器(qi)件。

功耗低(di)：采用優(you)結構(gou)設計，自身功耗低(di)。

數據(ju)回傳(chuan)：IC卡(ka)能(neng)將表總用(yong)（購）電量等(deng)信息回傳(chuan)到管理機，及時掌握用(yong)電情況。

報警功能：剩(sheng)余電量不足，先后報警燈(deng)閃爍(shuo)和斷(duan)電提醒購電。

自(zi)動斷電：剩余電量為零斷電，插卡不能恢復供電，直到再次購電。

電(dian)(dian)量(liang)查詢：插卡后循環(huan)顯示累(lei)計電(dian)(dian)量(liang)、總購電(dian)(dian)量(liang)及(ji)剩余電(dian)(dian)量(liang)。

抗破(po)壞能力強(qiang)：卡座(zuo)受到人為破(po)壞，內部(bu)計(ji)量(liang)，控制不受影響。

一表一卡：電(dian)(dian)卡經特殊的加(jia)密(mi)算法僅用于(yu)一塊表，防止(zhi)技術性竊電(dian)(dian)。
