Txhim kho qhov ntau ntawm qhov tam sim no ntau yam ntawm lub clamp ammeter
Yog tias qhov tam sim no ntawm Circuit Court yuav tsum tau kuaj yog tsawg dua qhov tam sim no ntawm qhov tsawg kawg nkaus ntawm lub clamp ammeter (xws li<5A), and the measured value cannot be read out, the wire of the circuit to be tested can be wound several times in the jaw (set as N circles). At this time Divide the current value indicated by the meter head by the number of turns N, which is the current value to be measured.
Yog hais tias qhov tam sim no yuav tsum tau ntsuas yog ntau tshaj qhov siab tshaj plaws tam sim no transformer. Txoj kev yog: txuas lub sij hawm ntawm lub tam sim no transformer nyob rau hauv lub load Circuit Court nyob rau hauv ib tug luv luv Circuit Court, clamp lub puab tsaig ntawm lub clamp ammeter rau hauv lub luv luv-circuit wire ntawm tus ncej thib ob, thiab muab cov ntsuas tam sim no los ntawm kev hloov pauv tam sim no. , uas yog ntsuas load tam sim no. tus nqi.
Cov teeb meem hauv qab no yuav tsum tau them sai sai rau thaum siv lub clamp ammeter:
Thaum ntsuas tam sim no me me, cov xaim nqa tam sim no tuaj yeem raug mob ob peb zaug thiab muab tso rau hauv lub puab tsaig rau kev ntsuas. Txawm li cas los xij, tus nqi tam sim no tuaj yeem tau txais los ntawm kev faib cov ntawv nyeem los ntawm tus lej ntawm cov coils. Tom qab kev ntsuas tiav lawm, muab qhov hloov pauv hloov mus rau qhov siab tshaj plaws ntawm txoj haujlwm (lossis tawm txoj haujlwm) kom muaj kev nyab xeeb rau lwm zaus.
Tsis txhob hloov lub zog thaum ntsuas.
Nco ntsoov tias qhov hluav taws xob ntawm lub voj voog yuav tsum qis dua qhov ntsuas tus nqi ntawm lub clamp ammeter, thiab qhov tam sim no ntawm high-voltage circuit tsis tuaj yeem ntsuas nrog lub clamp ammeter, txwv tsis pub muaj xwm txheej lossis hluav taws xob poob siab tuaj yeem tshwm sim tau yooj yim.
Yuav ua li cas siv lub clamp ammeter
Thaum ntsuas tam sim no, koj tsuas yog yuav tsum tau clamp cov hlau los ntsuas hauv cov tub ntxhais ntawm clip-on ammeter, thiab tom qab ntawd nyeem cov ntawv nyeem ntawm cov duab digital lossis cov cim qhia. Nws yog ib qho yooj yim mus use. Tsuas yog clamp cov xov hlau ntsuas kom nruj. Txawm li cas los xij, nrog kev siv dav dav ntawm digital clamp ammeters, ntau lub zog tau ntxiv rau lub clamp ammeter, xws li voltage, kub, tsis kam, thiab lwm yam. ) Cov haujlwm sib txawv tuaj yeem xaiv tau los ntawm kev tig lub pob, thiab txoj kev siv yog zoo ib yam li cov khoom siv digital multimeter. Rau lub ntsiab lus ntawm qee cov nyees khawm tshwj xeeb, thov saib cov lus qhia sib xws.
