結構原理

儀表采用(yong)相(xiang)位(wei)差轉換(huan)成電壓信號(hao).將U-I相(xiang)位(wei)差變換(huan) 為：DC 0～3號(hao),驅動(dong)測量機構，指示相(xiang)應的功(gong)率(lv)因數。

被測電(dian)(dian)(dian)(dian)壓(ya)由電(dian)(dian)(dian)(dian)阻分壓(ya)，斬(zhan)波(bo)(bo)器變為(wei)矩形(xing)波(bo)(bo),被測電(dian)(dian)(dian)(dian)流及 互感器,取樣(yang)電(dian)(dian)(dian)(dian)阻后，經移(yi)相(xiang)，斬(zhan)波(bo)(bo)后也變為(wei)矩形(xing)波(bo)(bo),兩(liang)信(xin)號 U、I送人異或門(men)，使脈沖(chong)寬(kuan)度與(yu)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流相(xiang)位(wei)差成(cheng)比例，此 信(xin)號經積分，放大和線性調整電(dian)(dian)(dian)(dian)絡(luo)輸(shu)出DC 0 ～3號，供 測量機構指(zhi)示。穩壓(ya)電(dian)(dian)(dian)(dian)路取自被測電(dian)(dian)(dian)(dian)壓(ya).經整流濾(lv)波(bo)(bo)穩壓(ya) 后,輸(shu)出± 12V,供各電(dian)(dian)(dian)(dian)路工(gong)作。
