Daim ntawv thov ntau yam thiab ua haujlwm ntawm clamp ammeter
Thaum ntsuas ntsuas tam sim no nrog cov ammeter tsis tu ncua, feem ntau nws yog feem ntau yuav tsum tau txiav tawm ntawm Circuit Court thiab nres lub tshuab ua ntej txuas cov ammetering cov ammeter rau kev ntsuas. Qhov no yog qhov teeb meem heev, thiab qee zaum nws tsis raug tso cai ua li ntawd kom nquag khiav motors. Txij ntawm no, siv cov ammeter clamp dhau los ua tau yooj yim dua li nws tuaj yeem ntsuas tam sim no tsis muaj kev txiav tawm ntawm Circuit Court. Tus txheej txheem ua hauj lwm ntawm Clamp Ammeter muaj raws li hauv qab no:
Qhov kev kuaj mob hluav taws xob hlau hla dhau ntawm cov hlau core los ua thawj kauj ntawm cov hloov pauv tam sim no, thiab tam sim no yog ntxias hauv cov kauj theem nrab ntawm tam sim no. Yog li hais tias lub Ammeter txuas rau theem theem qub chev tuaj yeem qhia tau tam sim no ntawm kev sim ntsuas hluav taws xob. Lub duab clamp tuaj yeem hloov pauv rau cov nyom sib txawv los ntawm kev hloov chaw. Tab sis nws tsis raug tso cai rau kev lag luam nrog hluav taws xob thaum lub zog hloov. Clamp Gauges feem ntau muaj qhov tseeb qis, feem ntau xws li los ntawm 2.5 txog 5 qib. Rau qhov yooj yim ntawm kev siv, tseem muaj kev hloov dua siab tshiab nrog cov sib txawv hauv lub rooj rau ntsuas cov ntsuas sib txawv tam sim no thiab hluav taws xob sib txawv
Tus mnemonic
Siv ib lub clamp ammeter ntsuas me me ac txawm
Cov kev sim thauj cov xaim hluav taws xob cov xaim xaim yog qhov txhab ib ncig ntawm lub clamp hlau tub ntxhais.
Qhov kev nyeem ntawv faib los ntawm Pauv Ntxiv rau ib qho muab qhov tseeb tam sim no tus nqi.
piav
Thaum kuaj xyuas seb puas muaj peb-theem tam sim no (tsawg dua 5 amps) ntawm ib lub taub hau me me yog} amps, thiab qee cov metres} amps, thiab qee cov metres muaj ib daim phiaj ntawm 2 amps. Nws yog qhov tseem ua tsis tau yooj yim hauv qab 2 amperes lossis ob peb yog kaum ntawm ib qho. Ib qho ntxiv, Ammeters feem ntau muaj qhov yuam kev loj ntawm cov nyom tsawg, thiab nws yog qhov nyuaj rau kev nyeem ntawv thaum tus taw qhia deviates. Txhawm rau kom ntsuas cov nqi tam sim no, lub rwb thaiv rwb thaiv cov xaim hluav taws xob tuaj yeem raug mob ib ncig ntawm ammeter clamp rau 1 rau n lem. Ua raws li lub hauv paus ntsiab lus ntawm cov hloov pauv tam sim no los txhim kho cov teb sib nqus, txhawm rau nyeem cov nqi tam sim no. Kev nyeem ntawv tau nyob rau hauv txoj kev no yog nthuav dav, tab sis qhov tseeb tam sim no tus nqi yuav tsum rho tawm qhov chaw dav. Thaum ntxiv ib qho tig, nyeem ntawv yuav tsum tau faib los ntawm 2; Faib los ntawm 3 Thaum Wind dawb. Txoj cai yog tias nrog n tig, tam sim no tau nce los ntawm n +1 lub sij hawm muab sib npaug los ntawm (n {10}}). Ib qho ntxiv, txhawm rau tshem tawm cov cawv ntawm cov khoom siv hlau nplaum nyob rau hauv cov tub ntxhais Ammeter, yog tias tau muab qhib ntau tam sim no tom qab tshem tawm cov khoom siv hlau nplaum uas muaj cov hlau txheem.
