2、1 電能計量單元工作原理

電(dian)能計(ji)量單元(yuan)工作原理

   被(bei)計量(liang)的(de)(de)每一(yi)相(xiang)電(dian)(dian)能(neng)的(de)(de)電(dian)(dian)流通(tong)過(guo)互感器采(cai)樣得(de)到電(dian)(dian)壓信(xin)號(hao)(hao),再通(tong)過(guo)ATT7026A芯片(pian)內(nei)部的(de)(de)差放(fang)電(dian)(dian)路將電(dian)(dian)壓信(xin)號(hao)(hao)放(fang)大,放(fang)大的(de)(de)信(xin)號(hao)(hao)經過(guo)A/D轉(zhuan)換成與(yu)其成比例的(de)(de)數字信(xin)號(hao)(hao),再經過(guo)高通(tong)濾(lv)波去(qu)除信(xin)號(hao)(hao)中(zhong)的(de)(de)直(zhi)流分量(liang)后進入數字乘法器的(de)(de)一(yi)個輸(shu)入端。被(bei)計量(liang)的(de)(de)電(dian)(dian)能(neng)電(dian)(dian)壓信(xin)號(hao)(hao)經過(guo)電(dian)(dian)阻分壓取(qu)樣，通(tong)過(guo)

 ATT7026A芯片內部的差放(fang)電(dian)路將信號放(fang)大(da)，再經過A/D轉(zhuan)換(huan)成與(yu)其成比例(li)的數字信號，進入數字乘法(fa)器的另一個(ge)輸入端與(yu)電(dian)流通道的信號進行乘法(fa)運

算，完成被計量電(dian)能的瞬時功率測量。每(mei)相輸出瞬時功率通(tong)過數(shu)字低(di)通(tong)濾波器,進行(xing)積分(fen)(fen)處理，然后進行(xing)絕(jue)對值累(lei)加(jia)后進入"數(shu)字/頻率"轉換器，經過分(fen)(fen)頻電(dian)路輸出的脈沖經過隔(ge)離后送入CPU單元進行(xing)處理，分(fen)(fen)別記錄有功和無功的總電(dian)量及(ji)有功反向(xiang)電(dian)量。
