結構原理

儀表采用(yong)相位差(cha)(cha)轉換成(cheng)電壓信(xin)號(hao).將U-I相位差(cha)(cha)變換 為：DC 0～3號(hao),驅動測(ce)量機構(gou)，指(zhi)示相應的功(gong)率(lv)因數。

被(bei)測電(dian)(dian)(dian)(dian)(dian)壓由(you)電(dian)(dian)(dian)(dian)(dian)阻分壓，斬(zhan)波(bo)(bo)器變為(wei)矩(ju)(ju)形波(bo)(bo),被(bei)測電(dian)(dian)(dian)(dian)(dian)流及(ji) 互感(gan)器,取(qu)(qu)樣電(dian)(dian)(dian)(dian)(dian)阻后，經(jing)移(yi)相，斬(zhan)波(bo)(bo)后也變為(wei)矩(ju)(ju)形波(bo)(bo),兩信(xin)號 U、I送人異或門(men)，使脈沖(chong)寬度與(yu)電(dian)(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)(dian)流相位(wei)差成比例，此 信(xin)號經(jing)積(ji)分，放大(da)和線性調(diao)整電(dian)(dian)(dian)(dian)(dian)絡輸出DC 0 ～3號，供 測量機構指示。穩壓電(dian)(dian)(dian)(dian)(dian)路取(qu)(qu)自(zi)被(bei)測電(dian)(dian)(dian)(dian)(dian)壓.經(jing)整流濾(lv)波(bo)(bo)穩壓 后,輸出± 12V,供各電(dian)(dian)(dian)(dian)(dian)路工作。

測量(liang)機構采(cai)用磁電系結構。
