Kev ntsuas txoj cai ntawm AC / DC clamp Ammeter
Feem ntau, Hall sensors yog siv los ntsuas DC tam sim no. Vim tias AC clamp meters siv tsis tau electromagnetic induction txoj kev. Lub Hall sensor tau muab tso rau raws li qhia hauv daim duab hauv qab no. Lub generated magnetic flux yog proportional rau lub ntsiab DC thiab AC tam sim no nyob rau hauv lub taub hau clamp. Qhov no yog kuaj pom los ntawm Hall sensor thiab siv los ua qhov tso zis hluav taws xob kom dissipate cov sib nqus flux
Hall sensor: Nws yog ib qho semiconductor uas tuaj yeem tsim kom muaj qhov sib npaug ntawm qhov sib npaug rau qhov kev tsis ncaj ncees tam sim no tsim los ntawm cov khoom ntsuas thiab tsim cov khoom siv hluav taws xob sib nqus thaum qhov kev tsis ncaj ncees tam sim no siv rau lub davhlau ya nyob twg.
Yuav ua li cas khiav lub clamp Ammeter?
Feem ntau, kev ua haujlwm ntawm AC clamp Ammeter ua raws li CT hauv paus ntsiab lus, uas feem ntau yog siv kom tau txais cov hlau nplaum sib nqus thaum tam sim no dhau los ntawm tus neeg xyuas pib. Piv txwv tias tam sim no dhau los ntawm tus neeg xyuas pib yog qhov tseem ceeb tam sim no, peb tuaj yeem tau txais qhov sib npaug tam sim no rau lub ntsiab tam sim no los ntawm electromagnetic induction generated los ntawm ob kauj ruam ntawm lub clamp (uas yog txuas nrog lub voj voog ntawm cov khoom kuaj). Qhov no tso cai rau peb nyeem AC tam sim no (thaum siv digital clamp Ammeter)
Thov xa mus rau lub flowchart hauv qab no kom paub meej:
Kev sib piv muaj nuj nqi:
Xaiv thiab teeb tsa cov txheej txheem rwb thaiv tsev qhov tseem ceeb hauv ntau qhov ntsuas thiab sib piv nrog kev nyeem ntawv.
Tau txais cov txiaj ntsig los ntawm kev sib piv qhov tsis ua haujlwm lossis dhau cov cim qhia pom ntawm lub vijtsam thiab ua tib zoo mloog rau lub suab nrov
Lub beep ceeb toom tuaj yeem cuam tshuam nrog kev ua tsis tiav lossis hla raws li cov neeg siv khoom xav tau
