Ua tib zoo saib peb cov ntsiab lus no thaum siv clamp Ammeter kom raug
Txij li thaum lub clamp Ammeter tuaj yeem ntsuas qhov tam sim no hauv Circuit Court yam tsis tau txiav tawm hauv Circuit Court, nws yog dav siv. Kev siv kom raug ntawm clamp Ammeter feem ntau yuav tsum tau them sai sai rau cov hauv qab no:
(1) Xaiv lub iav kom raug.
Ua ntej ntsuas qhov tam sim no, nws yuav tsum tau kwv yees kwv yees qhov loj ntawm qhov ntsuas tam sim no raws li qhov loj ntawm cov khoom thauj thiab xaiv qhov tsim nyog. Thaum nws tsis tuaj yeem kwv yees, qhov loj dua tuaj yeem siv ua ntej, thiab tom qab ntawd ib qho kev tsim nyog tuaj yeem hloov pauv raws li qhov loj ntawm qhov ntsuas tam sim no. Txawm li cas los xij, cov hlau ntsuas yuav tsum muab tso rau sab nraum lub bayonet ntawm lub clamp Ammeter thaum hloov.
(2) Qhov chaw tso ntawm qhov ntsuas hlau yuav tsum raug.
Thaum ntsuas qhov tam sim no ntawm cov hlau, qhov ntsuas tam sim no nqa cov hlau yuav tsum muab tso rau hauv qhov chaw nruab nrab hauv qhov clamp; Thaum ntsuas qhov tam sim no, tshem tawm cov hlau nplaum txav tau los ntawm lub puab tsaig thiab muab ib lub xaim ntawm lub cev muaj zog rau hauv nruab nrab ntawm lub puab tsaig.
(3) Kev siv ib puag ncig.
Khaws kom deb ntawm qhov chaw sib nqus muaj zog (xws li hluav taws xob tsis siv neeg siab tswj, hlau nplaum, thiab lwm yam) kom deb li deb tau, thiab siv clamp Ammeter kom txo tau qhov cuam tshuam ntawm magnetic teb ntawm clamp Ammeter.
Nws txoj haujlwm ua haujlwm yog raws li hauv qab no: clamp Ammeter muaj tam sim no transformer thiab Ammeter. Cov tub ntxhais hlau ntawm lub transformer muaj qhov txav tau thiab txuas nrog tus kov. Thaum siv, nias lub kov kom qhib lub cev hlau txav tau. Muab cov hlau ntawm qhov ntsuas tam sim no rau hauv lub clamp, tso tus kov, thiab kaw cov tub ntxhais hlau. Nyob rau ntawm lub sijhawm no, cov xaim dhau los ntawm qhov tam sim no sib npaug rau thawj winding ntawm lub transformer, thiab lub 'meter' tam sim no txuas nrog rau ob qho kawg ntawm qhov thib ob winding. Yog li ntawd, tam sim no qhia los ntawm nws yog tam sim no nyob rau hauv lub thib ob winding, uas yog proportional rau tam sim no nyob rau hauv lub lag luam. Yog li ntawd, qhov txo qhov ntsuas yog coj raws li qhov tam sim no kom muaj nuj nqis cuam tshuam rau thawj sab. Thaum muaj tam sim no nyob rau hauv tus neeg xyuas pib, tus pointer ntawm lub Ammeter txuas nrog rau qhov thib ob winding yuav deflect proportionally los qhia tus nqi ntawm qhov ntsuas tam sim no.
Lub clamp meter zoo ib yam li cov clamp hauv qhov tsos. Thaum siv, tus neeg xyuas pib hla lub clamp hlau tseem ceeb, yog li nws yog hu ua clamp meter lossis clamp Ammeter, uas yog hom Ammeter feem ntau siv los ntawm cov neeg ua haujlwm hluav taws xob. Thaum ntsuas qhov tam sim no ntawm Circuit Court nrog Ammeter zoo tib yam, Circuit Court yuav tsum raug txiav tawm thiab txuas nrog Ammeter. Lub clamp 'meter' tuaj yeem ntsuas qhov tam sim no yam tsis tau txiav tawm Circuit Court, uas yog qhov loj tshaj ntawm clamp Ammeter. Vim qhov yooj yim ntawm kev ntsuas tam sim no, nws yog dav siv.
Clamp Ammeter feem ntau tuaj yeem muab faib ua hom magnetoelectric thiab hom electromagnetic. Hom hlau nplaum yog siv los ntsuas lub zog zaus AC lub zog, thaum lub tshuab electromagnetic yog ob lub hom phiaj AC thiab DC. Tsis tas li ntawd, muaj cov digital clamp Ammeter, uas muaj qhov zoo ntawm kev nyeem ntawv intuitive, raug siab, siv tau yooj yim, thiab lwm yam, thiab nws kuj muaj qhov ntsuas kev ua haujlwm ntawm AC thiab DC voltage, tsis kam, diode ntawm digital multimeter.
