結構原理

儀容儀表將U-I相位差切換為DC 0?3V電壓降網絡信號，驅動軟件 檢測的平臺,指示箭頭某些的熱效率質因數。相位差-相電壓調節用電線路用于內附或外附，其方框圖下面的。

被測(ce)(ce)電(dian)(dian)(dian)(dian)壓(ya)(ya)由電(dian)(dian)(dian)(dian)阻(zu)分(fen)壓(ya)(ya)、斬(zhan)波器變為矩形波，被測(ce)(ce)電(dian)(dian)(dian)(dian)流(liu)經 互感(gan)器，取樣電(dian)(dian)(dian)(dian)阻(zu)后(hou)(hou),經移相、斬(zhan)波后(hou)(hou)也變為矩形波，兩信(xin)號(hao) U、I送人異或門，使脈沖寬(kuan)度與電(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)流(liu)相位差(cha)成比例(li)，此 信(xin)號(hao)經積分(fen)、放大(da)和(he)線性調整電(dian)(dian)(dian)(dian)路輸出DC 0?3號(hao)，供(gong) 測(ce)(ce)量(liang)機構指(zhi)示。穩壓(ya)(ya)電(dian)(dian)(dian)(dian)路取自被測(ce)(ce)電(dian)(dian)(dian)(dian)壓(ya)(ya)，經整流(liu)濾波穩壓(ya)(ya) 后(hou)(hou)，輸出±12V,以供(gong)各電(dian)(dian)(dian)(dian)路工(gong)作。
