Classification ntawm clamp ammeter
Clamp ammeters tuaj yeem muab faib ua hom pointer thiab hom digital raws li cov qauv sib txawv ntawm qhov ntsuas ntsuas; los ntawm kev ntsuas voltage, muaj cov high-voltage clamp ammeters thiab low-voltage clamp ammeters; los ntawm kev ua haujlwm, muaj AC-DC clamp meters, AC clamp meter, clamp multimeter, thiab to tam sim no clamp meter; Raws li cov qauv thiab cov hauv paus ntsiab lus ntawm kev ua haujlwm, lawv tau muab faib ua cov txheej txheem rectification thiab electromagnetic system. Lub rectifier clamp ammeter tsuas yog siv tau rau kev ntsuas ntawm AC tam sim no, thaum lub tshuab hluav taws xob clamp ammeter tuaj yeem paub txog AC thiab DC ntsuas. Lub tshuab electromagnetic clamp ammeter feem ntau yog tsim los ntawm kev hloov pauv tam sim no, magnetoelectric ammeter, rectifier circuit, ntau yam hloov pauv hloov thiab ntsuas Circuit Court. Cov tub ntxhais hlau ntawm lub tam sim no transformer yog ib tug clamp-zoo li tus qauv, uas yog muab faib mus rau hauv ib tug taag ib feem thiab ib tug movable ib feem, thiab muab tso rau pem hauv ntej kawg ntawm lub tam sim no transformer. Qhov chaw txav tau yog txuas nrog lub ciaj ntswj; Thaum lub ntswj ntsia hlau, cov tub ntxhais hlau ntawm lub tshuab hloov tam sim no yuav qhib tau, kom cov hlau ntawm qhov ntsuas tam sim no tuaj yeem dhau los ntawm qhov sib txawv ntawm cov tub ntxhais hlau yam tsis tau txiav tawm, thiab tom qab ntawd so tes kom kaw cov tub ntxhais hlau. . Nyob rau lub sijhawm no, cov xaim hla tam sim no sib npaug rau thawj kauj ntawm lub tshuab hloov tam sim no, thiab cov kauj ruam thib ob yuav muaj qhov cuam tshuam tam sim no, thiab tus taw tes ntawm ammeter txuas nrog lub kauj kauj ruam thib ob yuav ua rau pom tus nqi. ntawm qhov ntsuas tam sim no. Qhov kev hloov pauv hloov pauv thiab hloov pauv hloov tau tuaj yeem paub txog ntau qhov kev ntsuas tam sim no ntawm lub clamp ammeter.
Xaiv Phau Ntawv Qhia rau Clamp Meters
(1) Ua ntej tshaj plaws, nws yuav tsum paub meej tias qhov ntsuas tam sim no yog AC lossis DC. Lub rectifier clamp ammeter tsuas yog tsim nyog rau kev ntsuas lub zog zaus tam sim no nrog qis waveform distortion thiab hloov zaus me ntsis, txwv tsis pub, kev ntsuas loj yuav tshwm sim. Rau lub tshuab electromagnetic clamp ammeter, txij li cov khoom deflection ntawm qhov txav ntawm qhov ntsuas mechanism tsis muaj dab tsi cuam tshuam nrog lub polarity ntawm tam sim no, nws tuaj yeem siv los ntsuas ob qho tib si AC tam sim no thiab DC tam sim no, tab sis qhov tseeb feem ntau kuj qis. Qhov tseeb ntawm lub clamp ammeter feem ntau suav nrog 2.5 qib, 3 qib, 5 qib, thiab lwm yam, thiab yuav tsum tau xaiv raws li kev ntsuas kev ntsuas thiab cov xwm txheej tiag tiag.
(2) Rau digital clamp ammeters, qhov kev nyeem ntawm qhov ntsuas ntsuas yog qhov yooj yim thiab yooj yim, thiab kev ntsuas kev ua haujlwm kuj tau nthuav dav ntau, xws li tuaj yeem ntsuas qhov tsis kam, diodes, qhov hluav taws xob, lub zog ua haujlwm, lub zog muaj zog, lub zog muaj zog. , parameters xws li zaus. Txawm li cas los xij, digital clamp ammeter tsis zoo tag nrho. Thaum lub electromagnetic cuam tshuam nyob rau hauv lub sij hawm ntsuas yog loj, cov kev ntsuas tso tawm yuav muaj discrete jumps, ua rau nws nyuaj rau paub meej tias tus nqi tam sim no; Yog hais tias tus pointer clamp ammeter yog siv, vim Lub damping nyhuv ntawm lub magnetoelectric mechanical meter nws tus kheej ua rau nws kuj qeeb teb rau muaj zog electromagnetic teb cuam tshuam. Qhov zoo tshaj plaws, ob txhais tes tsim lub viav vias me me, thiab nws qhov kev taw qhia ntau yog qhov nkag siab zoo. Hais txog kev nyeem ntawv tsis nyuaj dhau. .
