Dab tsi yog qhov clamp meter txoj kev taw qhia?
Lub clamp 'meter' yog qhov tseem ceeb ntawm kev hloov pauv tam sim no, lub tshuab hluav taws xob clamp thiab lub tshuab magnetic rectifying nrog cov tshuaj tiv thaiv quab yuam.
Lub clamp meter ua haujlwm ntawm tib lub hauv paus ntsiab lus xws li transformer.
Thawj kauj yog cov xaim uas dhau los ntawm lub clamp-hom hlau core, uas yog sib npaug rau cov kauj ruam tseem ceeb ntawm 1-tig transformer, uas yog ib kauj ruam-up transformer. Secondary coil thiab ammeter rau kev ntsuas yog lub voj thib ob.
Thaum cov hlau muaj qhov hloov pauv tam sim no dhau los ntawm nws, nws yog qhov tig ntawm lub kauj uas ua kom muaj qhov sib nqus sib nqus, thiab qhov cuam tshuam tam sim no yog tsim nyob rau hauv lub voj voog thib ob. Qhov sib piv ntawm qhov loj ntawm qhov tam sim no mus rau lub hauv paus tam sim no yog sib npaug rau qhov sib piv ntawm cov lem ntawm lub hauv paus thiab theem nrab coils. .
Lub clamp ammeter yog siv los ntsuas cov dej ntws loj. Yog tias qhov tam sim no tsis loj txaus, thawj cov xaim tuaj yeem dhau los ntawm lub ntsuas hluav taws xob kom nce tus naj npawb ntawm cov lem, thiab tib lub sij hawm faib cov ntsuas tam sim no los ntawm tus lej ntawm cov lem.
Qhov thib ob winding ntawm feedthrough tam sim no transformer ntawm lub clamp ammeter yog qhov txhab ntawm cov tub ntxhais hlau thiab txuas nrog AC ammeter, thiab nws cov thawj winding yog ntsuas cov hlau hla dhau qhov nruab nrab ntawm lub transformer.
Lub pob qhov rooj yog qhov kev xaiv ntau yam hloov pauv, thiab qhov ua haujlwm ntawm tus ciaj ntswj yog qhib thiab kaw qhov txav tau ntawm cov tub ntxhais ntawm cov hloov pauv hloov pauv kom nws tuaj yeem clamp cov hlau hauv kev sim.
Thaum ntsuas tam sim no, nias lub ciaj ntswj, qhib lub puab tsaig, thiab muab cov xaim nqa tam sim no nyob rau hauv kev sim nyob rau hauv nruab nrab ntawm cov khoom noj tam sim no transformer, thaum muaj qhov hloov pauv tam sim no dhau los ntawm cov hlau hauv kev sim;
Qhov sib nqus flux ntawm qhov hloov tam sim no induces ib tug tam sim no nyob rau hauv lub thib ob winding ntawm lub transformer, thiab tam sim no dhau los ntawm lub kauj ntawm lub electromagnetic ammeter mus deflect lub pointer thiab qhia qhov ntsuas tam sim no tus nqi ntawm lub dial scale.
Hais txog tus qauv thiab lub hauv paus ntsiab lus ntawm clamp meter
Cov lus qhia
(1) Kev kho tshuab xoom yuav tsum tau ua ntej ntsuas
(2) Xaiv qhov tsim nyog, xaiv qhov loj ua ntej, thiab tom qab ntawd xaiv qhov me me lossis saib daim ntawv teev npe rau kev kwv yees.
(3) Thaum siv qhov ntsuas qhov ntau thiab qhov kev nyeem ntawv tsis pom tseeb, cov hlau ntsuas tuaj yeem raug mob ob peb zaug, thiab tus lej ntawm qhov kev hloov yuav tsum yog raws li tus naj npawb ntawm tig hauv nruab nrab ntawm lub puab tsaig, tom qab ntawv nyeem {{ 1}} qhia tus nqi × ntau yam / tag nrho sib txawv × tus naj npawb ntawm cov lem
(4) Tom qab kev ntsuas tiav, qhov hloov pauv hloov yuav tsum muab tso rau ntawm qhov ntau.
(5) Thaum ntsuas, cov hlau nyob hauv kev sim yuav tsum nyob hauv nruab nrab ntawm lub puab tsaig, thiab lub puab tsaig yuav tsum raug kaw kom nruj kom txo tau qhov yuam kev.
