Dab tsi yog Transformer Clamp Ammeter
Lub clamp 'meter' yog qhov tseem ceeb ntawm kev hloov pauv tam sim no, lub tshuab hluav taws xob clamp thiab cov txheej txheem magnetoelectric 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 cov ntsuas xaim dhau los ntawm qhov nruab nrab ntawm lub transformer. Lub pob qhov rooj yog qhov kev xaiv ntau yam, thiab qhov kev ua haujlwm ntawm tus ciaj ntswj yog qhib thiab kaw qhov txav tau ntawm cov tub ntxhais ntawm cov khoom siv los ntawm kev 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 nruab nrab ntawm cov khoom noj tam sim no. Ib tug tam sim no yog induced nyob rau hauv sab winding, thiab tam sim no dhau los ntawm lub kauj ntawm lub electromagnetic ammeter, ua rau lub pointer deflect, thiab ntsuas tam sim no tus nqi yog qhia nyob rau hauv dial scale.
Tom qab muab cov xaim nyob rau hauv kev sim rau hauv lub qhov rais los ntawm lub pob tseem ceeb, xyuam xim rau qhov zoo haum ntawm ob sab ntawm lub puab tsaig, thiab tsis txhob cia lwm yam khoom nyob rau hauv nruab nrab;
Qhov tsawg kawg nkaus ntawm lub ntsuas ntsuas clamp yog 5A, thiab qhov yuam kev ntawm cov zaub yuav loj dua thaum ntsuas qhov me me tam sim no. Qhov no yog qhov tshwm sim uas tuaj yeem ntsuas tau tom qab winding lub zog hluav taws xob ntawm lub ntsuas hluav taws xob clamp rau ob peb lub lis piam, thiab faib cov txiaj ntsig tau txais los ntawm tus lej ntawm kev tig.
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 z me me ntsuas ntsuas, kev nyeem ntawv tsis pom tseeb, koj tuaj yeem cua ntsuas cov hlau ob peb tig, tus lej hloov yuav tsum yog raws li tus naj npawb ntawm tig hauv nruab nrab ntawm lub puab tsaig, tom qab ntawv nyeem {{ 1}} qhov taw qhia tus nqi × ntau yam / tag nrho qhov sib txawv × Tus lej hloov
(4) Tom qab kev ntsuas tiav, qhov hloov pauv yuav tsum tau muab tso rau ntawm qhov siab tshaj plaws.
(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.
Cov kev ceev faj
(1) Qhov voltage ntawm kab nyob rau hauv kev ntsuam xyuas yuav tsum qis dua qhov ntsuas voltage ntawm lub ntsuas clamp.
(2) Thaum ntsuas qhov tam sim no ntawm cov kab hluav taws xob siab, hnav cov hnab looj tes insulating, hnav cov khau insulating, thiab sawv ntsug ntawm ib lub lev insulating.
(3) Lub puab tsaig yuav tsum raug kaw kom nruj thiab tsis tuaj yeem hloov pauv nrog lub hwj chim.
