AC clamp ammeter ntsuas tam sim no tus qauv
Nyob rau hauv txoj kab nrog loj tam sim no, nws yog feem ntau muaj kev ruaj ntseg siv clamp ammeter los ntsuas;
Ua ntej teeb tsa lub multimeter rau lub iav tam sim no, thiab tom qab ntawd txuas nws hauv series hauv Circuit Court ntawm qhov tam sim no ntsuas. Nws yuav tsum raug sau tseg tias yog tias nws yog DC Circuit Court, xyuam xim rau qhov polarity. Txawm hais tias ntsuas tam sim no lossis qhov hluav taws xob, lub ammeter yuav tsum tau hloov kho rau cov iav sib thooj, uas yog, lub iav ntawm lub ntsuas yuav tsum siab dua qhov voltage lossis tam sim no tus nqi ntawm cov khoom ntsuas. Kho kom siab tshaj tus nqi thaum tsis paub.
Thaum ntsuas tam sim no, lub ammeter yuav tsum tau txuas nrog hauv series nrog lub load, vim hais tias tam sim no nyob rau hauv series Circuit Court yog sib npaug rau txhua qhov chaw, yog li tam sim no dhau los ntawm ammeter yog qhov load tam sim no. Yog tias nws tsis raug txuas nrog, nws txuas nrog rau qhov sib npaug nrog lub nra, vim tias qhov kev tiv thaiv sab hauv ntawm lub ammeter yog me me, thiab nyob rau hauv qhov hluav taws xob ntawm qhov load, cov tam sim no loj yuav dhau los ntawm nws, uas yuav ua rau lub ammeter puas.
Thaum ntsuas qhov hluav taws xob, nws yuav tsum tau txuas lub voltmeter nyob rau hauv parallel nrog lub load, vim hais tias nyob rau hauv lub parallel Circuit Court, qhov voltage nyob rau hauv tej ceg yog sib npaug zos, uas yog, qhov voltage ntawm ob kawg ntawm lub voltmeter yog qhov tseeb voltage ntawm lub load, Yog hais tias lub 'meter' tau muab tso rau hauv lub load Circuit Court, nws tsis tuaj yeem ntsuas qhov tseeb voltage.
Tus qauv ntawm lub clamp ammeter yog qhov tseeb AC tam sim no transformer. Nws yog sib npaug rau lub transformer nrog tsuas yog ib tug thawj tig thiab ntau theem nrab lem, thiab lub thib ob load yog yav dhau los AC ammeter.
Thaum lub clamp ammeter clamps ib theem kab, nws yog sib npaug rau muaj thawj winding. Lub sijhawm no, kev ua haujlwm tam sim no ua rau cov hlau nplaum sib nqus hauv cov hlau nplaum ntawm lub clamp ammeter, thiab cov hlau nplaum sib nqus hla dhau los ntawm cov cua ntsawj ntshab thib ob kom ua rau cov hluav taws xob theem nrab thiab tsim ib qho tam sim no hauv cov khoom nruab nrab. Qhov loj ntawm qhov nruab nrab tam sim no yog ncaj qha proportional rau thawj tam sim no, yog li tus nqi qhia los ntawm lub ntsuas lub taub hau tuaj yeem cuam tshuam ncaj qha rau qhov loj ntawm thawj qhov chaw ua haujlwm tam sim no. Yog li nws tsis tas yuav tawg lub Circuit Court los ntsuas tam sim no.
