Clamp meter ua hauj lwm hauv paus ntsiab lus Clamp meter classification
Clamp ammeter hu ua clamp meter, yog ib txheej ntawm tam sim no transformer thiab ammeter nyob rau hauv ib qho cuab yeej, nws txoj kev ua hauj lwm thiab tam sim no transformer tam sim no ntsuas yog tib yam. Nws qhov ua haujlwm feem ntau yog siv lub tshuab hluav taws xob electromagnetic thiab los ntawm-centre hom tam sim no transformer. Los ntawm lub plawv hom tam sim no transformer core ua los ntawm movable qhib, thiab mus rau hauv ib tug clamp, yog li lub npe clamp ammeter. Tsis tas yuav tsum tau txiav tawm Circuit Court tuaj yeem ntsuas ncaj qha Circuit Court AC tam sim no portable instrumentation, hluav taws xob tu hauv kev siv yooj yim heev, dav siv.
Clamp meter ua haujlwm txoj cai
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub clamp meter yog tib yam li ntawm lub transformer. Thawj kauj yog los ntawm lub clamp tub ntxhais hlau, sib npaug rau 1 tig ntawm thawj kauj ntawm lub transformer, uas yog ib kauj ruam-up transformer. Secondary coil thiab ammeter siv rau kev ntsuas daim ntawv thib ob Circuit Court. Thaum cov hlau muaj qhov hloov pauv tam sim no los ntawm, nws yog qhov tig ntawm lub kauj ua ib qho chaw sib nqus sib nqus, nyob rau hauv qhov thib ob Circuit Court tsim ib qho induced tam sim no, qhov loj ntawm qhov tam sim no thiab qhov piv ntawm cov thawj tam sim no, uas yog sib npaug rau inverse. ratio ntawm tus naj npawb ntawm lem ntawm lub hauv paus thiab theem nrab coils. Clamp ammeter yog siv los ntsuas qhov loj tam sim no, yog tias qhov tam sim no tsis loj txaus, koj tuaj yeem nce tus naj npawb ntawm cov neeg xyuas pib nyob rau hauv los ntawm clamp meter, tib lub sij hawm tus naj npawb ntawm ntsuas tam sim no muab faib los ntawm tus lej ntawm cov lem. Clamp ammeter los ntawm cov tub ntxhais ntawm tam sim no transformer winding nyob rau sab thib ob ntawm cov tub ntxhais thiab txuas nrog AC ammeter, nws thawj winding uas yog los ntawm qhov chaw ntawm transformer ntsuas hlau. Lub pob qhov rooj yog qhov hloov pauv ntau yam, thiab lub luag haujlwm ntawm lub spanner yog qhib thiab kaw qhov txav ntawm lub hauv paus ntawm cov tub ntxhais transformer txhawm rau ua kom nws clamp cov hlau ntsuas. Kev ntsuas tam sim no, nias lub spanner, qhib lub puab tsaig, ntsuas tam sim no-nqa tus neeg xyuas pib muab tso rau hauv nruab nrab ntawm qhov hnav-centred tam sim no transformer, thaum ntsuas tus neeg xyuas pib muaj qhov hloov pauv tam sim no los ntawm kev hloov pauv tam sim no hauv lub transformer lwm sab ntawm lub winding induces ib tug tam sim no, uas dhau los ntawm lub kauj ntawm lub electromagnetic ammeter, thiaj li hais tias tus pointer yog deflected nyob rau hauv lub dial scale taw qhia tias qhov ntsuas tam sim no tus nqi.
Clamp meter classification
Raws li nws cov qauv thiab kev siv yog muab faib ua ob hom inductor thiab electromagnetic system. Feem ntau siv yog transformer hom clamp ammeter, los ntawm tam sim no transformer thiab rectifier system instrumentation. 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.
Clamp Meter nta
Clamp meter tuaj yeem hloov mus rau ntau qhov sib txawv los ntawm kev hloov lub zog. Txawm li cas los xij, kev hu xov tooj tsis raug tso cai ua haujlwm nrog hluav taws xob. Clamp meter dav dav tsis siab, feem ntau 2.5 ~ 5 qib. Txhawm rau kom yooj yim rau kev siv lub rooj, muaj ntau qhov sib txawv ntawm kev hloov pauv rau kev ntsuas qhov sib txawv ntawm qhov ntsuas tam sim no thiab qhov ntsuas hluav taws xob muaj nuj nqi. Clamp meter tau pib siv los ntsuas AC tam sim no, tab sis tam sim no lub multimeter muaj cov haujlwm nws kuj muaj, tuaj yeem ntsuas AC thiab DC voltage, tam sim no, capacitance, diode, transistor, tsis kam, kub, zaus thiab lwm yam.
