Cov ntsiab lus tseem ceeb ntawm kev siv clamp ammeter
Clamp meter (clamp meter) yog ib qho cuab yeej uas sib xyaw ua ke tam sim no transformer thiab ammeter. Nws yog ib ceg tseem ceeb ntawm digital multimeter. Nws txoj hauv kev ua haujlwm yog tib yam li qhov tam sim no transformer rau ntsuas tam sim no. Lub clamp meter yog ib qho kev sib txuas ntawm lub tam sim no transformer thiab ammeter. Cov tub ntxhais hlau ntawm qhov tam sim no transformer tuaj yeem qhib thaum lub qhov ciaj ntswj nruj; cov hlau los ntawm kev ntsuas tam sim no tuaj yeem dhau los ntawm qhov sib txawv uas qhib los ntawm cov tub ntxhais hlau tsis raug txiav tawm, thiab cov tub ntxhais hlau raug kaw thaum lub qhov ciaj ntswj raug tso tawm. Lub ntsuas hluav taws xob ntsuas hluav taws xob dhau los ntawm cov tub ntxhais hlau ua lub hauv paus kauj ntawm lub tam sim no transformer, thiab tam sim no yog induced nyob rau hauv lub thib ob kauj los ntawm hla lub tam sim no. Yog li ntawd lub ammeter txuas nrog lub kauj thib ob muaj qhov taw qhia ----- ntsuas qhov tam sim no ntawm kab nyob rau hauv kev sim.
Lub clamp meter tuaj yeem hloov mus rau ntau qhov sib txawv los ntawm kev hloov lub iav ntawm qhov hloov. Tab sis nws tsis raug tso cai ua haujlwm nrog hluav taws xob thaum hloov cov iav. Lub clamp meter feem ntau tsis siab rau qhov tseeb, feem ntau yog nyob rau hauv thaj tsam ntawm 2.5 mus rau 5. Rau qhov yooj yim ntawm kev siv, muaj cov keyboards sib txawv ntawm cov 'meter' rau kev ua haujlwm ntawm kev ntsuas qhov sib txawv ntawm qhov tam sim no thiab ntsuas qhov voltage.
Lub clamp meter z yog Ameslikas siv los ntsuas AC tam sim no, tab sis tam sim no nws kuj muaj qee qhov haujlwm ntawm multimeter, uas tuaj yeem ntsuas AC thiab DC voltage, tam sim no, capacitance, diode, transistor, tsis kam, kub, zaus thiab lwm yam.
Lub clamp meter yog ib lub 'meter' siv los ntsuas qhov loj ntawm qhov tam sim no nyob rau hauv ib qho hluav taws xob khiav hluav taws xob, thiab nws tuaj yeem ntsuas qhov tam sim no yam tsis muaj kev cuam tshuam ntawm lub zog. Nws yog ib qho khoom siv hluav taws xob tshwj xeeb tsim los ntsuas AC loj tam sim no.
Clamp ammeter tseem hu ua clamp meter, Taiwan yog hu ua nuv meter.
Lub clamp ammeter yog ib qho yooj yim ntsuas ntsuas (tseem hu ua kev ntsuas tsis muaj kev puas tsuaj) uas clamps cov xaim thiab kuaj xyuas qhov tam sim no yam tsis tau txiav tawm hauv Circuit Court.
Analog pointer multimeters thiab digital multimeters txiav tawm Circuit Court kom paub qhov tam sim no, thaum lub clamp ammeter tsuas yog clamped ntawm lub sheath ntawm lub zog hlau los xyuas qhov tam sim no. Kev ua haujlwm yog yooj yim, thiab nws tuaj yeem kuaj xyuas cov dej ntws loj yam tsis muaj kev sib txuas ncaj qha.
Muaj ob hom clamp meters, multimeters thiab rwb thaiv tsev ntsuas ntsuas, analog pointer thiab digital.
Kev tshawb nrhiav ntau yam ntawm cov qauv qauv: AC thiab DC nyob ib puag ncig 2A txog 200A lossis 400A, thiab tseem muaj cov khoom lag luam uas tuaj yeem ntes cov tam sim no siab ntawm 2000A;
Kuj tseem muaj cov khoom siv hluav taws xob uas tuaj yeem kuaj xyuas me me tam sim no ntawm ob peb mA, thiab cov khoom lag luam uas tuaj yeem txheeb xyuas qhov muaj txiaj ntsig zoo (True RMS) ntawm cov nthwv dej uas tsis yog sine nthwv dej xws li cov khoom siv hluav taws xob hloov pauv thiab hloov cov khoom siv hluav taws xob.
Clamp Meter Qhov tseem ceeb
1: detection object
Xaiv cov qauv raws li cov khoom sib txawv, AC tam sim no, DC tam sim no, lossis tam sim no to;
2: Ntes tau z loj tshaj tus neeg xyuas pib specification
Raws li qhov chaw sim, muaj qhov sib txawv ntawm 21mm txoj kab uas hla mus rau 53mm txoj kab uas hla.
3: Puas yog qhov tseeb tus nqi nrhiav kom pom?
Lub clamp ammeter siv qhov nruab nrab tus nqi hom tsis tuaj yeem txheeb xyuas qhov tsis yog-sinusoidal Circuit Court xws li lub cev muaj zog thiab Circuit Court ntawm transformer. Lub clamp ammeter ntawm qhov tseeb tus nqi hom yuav tsum tau siv los xyuas qhov Circuit Court no.
4: Lwm cov haujlwm
Tsis tsuas yog tuaj yeem ntes tau qhov tam sim no, tab sis kuj yog ib qho qauv uas sib koom ua ke ntawm kev tshawb pom muaj nuj nqi thiab cov ntaub ntawv tso tawm.
Clamp Meter Classification
Raws li nws cov qauv thiab kev siv, nws muab faib ua ob hom: transformer hom thiab electromagnetic system.
Feem ntau siv yog transformer-hom clamp ammeter, uas yog tsim los ntawm ib tug tam sim no transformer thiab ib tug rectifier system ntsuas. Nws tsuas tuaj yeem ntsuas AC tam sim no. Lub deflection ntawm qhov txav ntawm qhov ntsuas hluav taws xob tsis muaj dab tsi cuam tshuam nrog lub polarity ntawm tam sim no, yog li nws tuaj yeem siv rau AC thiab DC.
