Tau paub qhov transformer clamp ammeter
Cov qauv thiab lub hauv paus ntsiab lus
Lub ntsuas hluav taws xob yog qhov tseem ceeb ntawm lub tshuab hluav taws xob tam sim no, lub tshuab hluav taws xob clamp, thiab lub tshuab hluav taws xob hluav taws xob hluav taws xob reactive quab yuam.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub clamp hom meter yog tib yam li ntawm transformer. Thawj kauj yog ib lub xaim uas dhau los ntawm lub clamp hom hlau core, uas yog sib npaug rau thawj kauj ntawm 1-tig transformer. Qhov no yog ib tug step-up transformer. Secondary coil thiab ammeter siv rau kev ntsuas daim ntawv thib ob Circuit Court. Thaum muaj AC tam sim no dhau los ntawm cov xaim, nws yog qhov sib txawv ntawm cov hlau nplaum uas tsim los ntawm cov kauj no, uas ua rau cov hluav taws xob tam sim no nyob rau hauv lub voj voog thib ob. Qhov loj ntawm qhov tam sim no yog proportional rau qhov kev faib ua feem ntawm cov thawj tam sim no, uas yog sib npaug rau qhov sib piv ntawm tus naj npawb ntawm cov lem nyob rau hauv thawj thiab thib ob coils. Lub clamp hom ammeter yog siv los ntsuas cov dej ntws loj. Yog tias qhov tam sim no tsis loj txaus, tus naj npawb ntawm cov lem ntawm ib lub xaim dhau los ntawm clamp hom ammeter tuaj yeem nce ntxiv, thiab ntsuas tam sim no tuaj yeem muab faib los ntawm tus lej ntawm cov lem.
Qhov thib ob winding ntawm cov tub ntxhais tam sim no transformer ntawm lub clamp ammeter yog qhov txhab nyob ib ncig ntawm cov tub ntxhais hlau thiab txuas nrog AC ammeter. Nws lub ntsiab winding yog ntsuas cov hlau hla los ntawm qhov chaw ntawm lub transformer. Lub pob qhov rooj yog qhov kev xaiv ntau yam, thiab kev ua haujlwm ntawm tus ciaj ntswj yog qhib thiab kaw qhov txav ntawm lub hauv paus ntawm cov tub ntxhais transformer, yog li txhawm rau txhawm rau txhawm rau ntsuas cov hlau.
Thaum ntsuas qhov tam sim no, nias lub ciaj ntswj, qhib cov pliers, thiab tso cov ntsuas tam sim no nqa cov hlau nyob hauv nruab nrab ntawm hom tam sim no transformer. Thaum muaj alternating tam sim no dhau los ntawm kev ntsuas cov hlau, qhov sib nqus flux ntawm cov alternating tam sim no induces ib tug tam sim no nyob rau hauv lub thib ob winding ntawm lub transformer. Qhov tam sim no dhau los ntawm lub kauj ntawm electromagnetic ammeter, ua rau lub pointer deflect thiab qhia txog qhov ntsuas tam sim no ntawm tus dial scale.
Tom qab tso cov hlau ntsuas rau hauv lub qhov rais los ntawm lub pob hlau tseem ceeb, nws yog ib qho tseem ceeb kom ntseeg tau tias ob sab ntawm lub clamp muaj qhov haum zoo thiab tsis muaj lwm yam khoom raug muab tso rau hauv nruab nrab;
Z-ntaus ntawm lub ntsuas ntsuas clamp yog 5A, thiab thaum ntsuas qhov me me tam sim no, qhov kev ua yuam kev yuav loj dua. Qhov no tuaj yeem ntsuas tau los ntawm winding lub zog xaim ntawm lub ntsuas hluav taws xob rau ob peb lub lem, thiab qhov tau txais kev nyeem ntawv yog muab faib los ntawm tus naj npawb ntawm lem kom tau txais qhov xav tau.
Kev siv
(1) Mechanical zeroing yuav tsum tau ua ntej ntsuas
(2) Xaiv qhov tsim nyog, ua ntej xaiv qhov loj, tom qab ntawd xaiv qhov me me lossis kwv yees tus nqi ntawm daim ntawv teev npe.
(3) Thaum siv qhov ntsuas me me nrog z, yog tias qhov kev nyeem ntawv tseem tsis tau meej meej, cov hlau ntsuas tuaj yeem raug mob ob peb zaug. Tus naj npawb ntawm cov lem yuav tsum yog nyob ntawm tus naj npawb ntawm tig nyob rau hauv nruab nrab ntawm lub clamp, thiab kev nyeem ntawv=qhia tus nqi x ntau / tag nrho qhov sib txawv x tus lej ntawm cov lem
(4) Tom qab qhov ntsuas tau ua tiav, tso qhov hloov pauv hloov mus rau ntau yam ntawm z.
(5) Thaum ntsuas, ntsuas cov hlau yuav tsum muab tso rau hauv nruab nrab ntawm lub clamp thiab lub clamp yuav tsum kaw kom nruj kom txo tau qhov yuam kev.
teeb meem xav tau kev saib xyuas
(1) Qhov hluav taws xob ntawm qhov ntsuas hluav taws xob yuav tsum qis dua qhov ntsuas hluav taws xob ntawm lub ntsuas hluav taws xob.
(2) Thaum ntsuas qhov tam sim no ntawm cov kab hluav taws xob siab, nws yog ib qho tsim nyog yuav tsum hnav cov hnab looj tes insulated, cov khau insulated, thiab sawv ntsug ntawm ib lub lev insulated.
(3) Lub puab tsaig yuav tsum kaw nruj nreem thiab tsis tuaj yeem hloov pauv nrog hluav taws xob.
