每經AI快訊，11月20日(ri)，記者(zhe)從中(zhong)國電(dian)(dian)(dian)(dian)(dian)科(ke)院武漢分(fen)院獲悉(xi)，經過兩年的(de)技(ji)術攻關，該院成功(gong)研發(fa)(fa)出帶電(dian)(dian)(dian)(dian)(dian)條(tiao)件下低壓(ya)電(dian)(dian)(dian)(dian)(dian)流互(hu)(hu)感器(qi)（即CT）全量程(cheng)校準(zhun)(zhun)設備(bei)，首次具備(bei)不(bu)停電(dian)(dian)(dian)(dian)(dian)狀態下對低壓(ya)電(dian)(dian)(dian)(dian)(dian)流互(hu)(hu)感器(qi)開展周期性(xing)檢定能力(li)。目前(qian)，該裝置已在國網上海(hai)市電(dian)(dian)(dian)(dian)(dian)力(li)公司等(deng)單(dan)位試點應(ying)用(yong)(yong)(yong)，后(hou)續將在全國多地開展掛(gua)網運行(xing)工(gong)作(zuo)。帶電(dian)(dian)(dian)(dian)(dian)校準(zhun)(zhun)是帶電(dian)(dian)(dian)(dian)(dian)作(zuo)業中(zhong)應(ying)用(yong)(yong)(yong)最廣的(de)技(ji)術之(zhi)一，能夠精準(zhun)(zhun)診斷(duan)故障(zhang)設備(bei)和(he)有效(xiao)發(fa)(fa)現運行(xing)安全隱(yin)患。此前(qian)常用(yong)(yong)(yong)的(de)方法是依賴于(yu)停電(dian)(dian)(dian)(dian)(dian)的(de)傳統(tong)檢測(ce)技(ji)術，停電(dian)(dian)(dian)(dian)(dian)檢測(ce)時間窗口較難協調(diao)，不(bu)利于(yu)營商環境和(he)供電(dian)(dian)(dian)(dian)(dian)可靠(kao)性(xing)；此外，采(cai)用(yong)(yong)(yong)帶電(dian)(dian)(dian)(dian)(dian)檢測(ce)手段僅能檢測(ce)用(yong)(yong)(yong)戶當(dang)前(qian)負載點的(de)誤差(cha)情況，不(bu)能全面反映用(yong)(yong)(yong)戶運行(xing)過程(cheng)中(zhong)所有實(shi)際誤差(cha)，準(zhun)(zhun)確度難以保證。（科(ke)技(ji)日(ri)報）
