三相电容电感测试仪原理探秘

三相电容电感测试仪厂家—上海J9九游会AG电气有限公司,针对在进行电容电感试验时的现场的实际情况,经过不断的研究开发,*终研制出一种利用新试验方法进行测量的三相电容电感测试仪。

    那么,三相电容电感测试仪原理是什么?

 


    三相电容电感测试仪原理是什么?三相电容电感测试仪可以在不拆线的状态下,测量成组并联电容器的单相电容或各种组合连接类型的三相电容器,同时也能够测量各种电抗器的电感。 

    在被测(ce)电(dian)(dian)(dian)(dian)(dian)容支路有(you)对被测(ce)电(dian)(dian)(dian)(dian)(dian)容的(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)压、电(dian)(dian)(dian)(dian)(dian)流取(qu)样(yang)的(de)(de)(de)取(qu)样(yang)电(dian)(dian)(dian)(dian)(dian)路,取(qu)样(yang)电(dian)(dian)(dian)(dian)(dian)路的(de)(de)(de)输(shu)出端分(fen)别接放(fang)大电(dian)(dian)(dian)(dian)(dian)路,从(cong)电(dian)(dian)(dian)(dian)(dian)压放(fang)大电(dian)(dian)(dian)(dian)(dian)路输(shu)出的(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)压信(xin)号和从(cong)电(dian)(dian)(dian)(dian)(dian)流放(fang)大电(dian)(dian)(dian)(dian)(dian)路输(shu)出的(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)流信(xin)号通(tong)过鉴相器输(shu)出相位差信(xin)号,与电(dian)(dian)(dian)(dian)(dian)压信(xin)号和电(dian)(dian)(dian)(dian)(dian)流。

    信号通过A/D转换(huan)器后,输(shu)入CPU计算(suan)而(er)得(de)到(dao)被(bei)测电容(rong)(rong)值。因为(wei)采用了移动的电流取样单(dan)元,而(er)使得(de)无需(xu)拆(chai)除连接(jie)线就可以(yi)直接(jie)测量(liang)电容(rong)(rong)值         

    加之测量过程(cheng)档位是(shi)自动(dong)进行(xing)选择(ze),避免了(le)手动(dong)操作引起的误(wu)差,因此具有稳定性(xing)好(hao)、重复性(xing)好(hao),准(zhun)确可靠(kao)的特点(dian)。
