交流電流變送器

1 概述

    交流(liu)(liu)電流(liu)(liu)變送器應用電磁感應原理，對電網中(zhong)的交流(liu)(liu)電流(liu)(liu)進行實時測量，采用恒(heng)流(liu)(liu)技術和線性(xing)溫度補償(chang)技術，將(jiang)其隔(ge)(ge)離變換為(wei)標準(zhun)的直流(liu)(liu)信號輸(shu)出。采用24伏或12伏安(an)全電壓供電，具有過(guo)載能力強、高精度、高隔(ge)(ge)離、高安(an)全性(xing)、低功耗等特點(dian)，可廣泛用于工(gong)業自動(dong)化領域。

    BA系列中(zhong)剩余電(dian)(dian)(dian)流傳感器于漏(lou)電(dian)(dian)(dian)監(jian)控，監(jian)測電(dian)(dian)(dian)氣(qi)(qi)線路或(huo)(huo)電(dian)(dian)(dian)氣(qi)(qi)設備(bei)絕緣(yuan)狀態，避免(mian)電(dian)(dian)(dian)氣(qi)(qi)線路或(huo)(huo)電(dian)(dian)(dian)氣(qi)(qi)設備(bei)絕緣(yuan)性能降低引起的事故。產品符合GB/T 13850-1998、GB 1208-2006
