Taw qhia rau Transformer Clamp Ammeter's Structure and Operating Principple
Shape meter (clamp meter) yog ib qho cuab yeej uas ua ke nrog tam sim no transformer thiab ammeter, thiab yog ib ceg tseem ceeb ntawm digital multimeter; Nws yog ib qho khoom siv portable uas tuaj yeem ntsuas ncaj qha rau AC tam sim no ntawm ib lub voj voog yam tsis muaj kev cuam tshuam lub voj voog.
Cov qauv thiab lub hauv paus ntsiab lus
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 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 qhov 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.
