Vim li cas ntsuas tam sim no nrog lub clamp ammeter thaum txhim kho lub cev muaj zog?
Qhov tseeb tam sim no ntawm ib theem kab yog ntsuas siv lub clamp hom ammeter, vim hais tias lub clamp hom ammeter yog sib npaug rau CT nrog qhib rau hauv thawj winding. Tam sim no kuaj pom nyob rau hauv ib qho kev xeem yuav raug cuam tshuam rau hauv qhov kev sim thib ob, uas tsis cuam tshuam rau txoj kev sib txuas ntawm peb-theem lub cev muaj zog.
Kauj Ruam 1: Ntsuas cov theem sib cais, uas tuaj yeem ntsuas ncaj qha rau theem voltage ntawm ob sab ntawm lub tshuab hluav taws xob hluav taws xob (tib yam li saum toj no), theem voltage tuaj yeem ntsuas ncaj qha rau ntawm qhov kawg ntawm lub ntsuas hluav taws xob. Txawm li cas los xij, nws yuav tsum tau muab tso rau ntawm ib qho kev sojntsuam thiab xaiv qhov tsim nyog. Nws "bayonet" tsuas yog ntsuas AC tam sim no nrog lub ntsuas ntsuas tshwj xeeb. Khaws tus taw tes rau ntawm sab xis thiab siv tib txoj kev raws li ib txwm siv multimeter, maj mam hloov ntawm qhov siab mus rau qis iav hauv qhov tsis paub qhov voltage;
Kauj Ruam 2: Ntsuas qhov hluav taws xob los ntawm kev sib txuas ntawm cov kev sojntsuam. Lub clamp meter ntsuas qhov voltage los ntawm nws nrog multimeter. Lub clamp meter tsis tuaj yeem ncaj qha "clamp" qhov voltage thiab hloov pauv hloov pauv mus rau qhov tsim nyog.
Kev siv cov digital clamp saib
1. Mechanical zero adjustment yuav tsum tau ua ntej ntsuas
2. Xaiv qhov tsim nyog, ua ntej xaiv qhov loj, ces xaiv qhov me me, lossis kwv yees tus nqi ntawm daim ntawv teev npe
3. Thaum siv qhov ntsuas qhov tsawg kawg nkaus thiab qhov kev nyeem ntawv tseem tsis tau pom tseeb, cov xov hlau ntsuas tuaj yeem raug mob ob peb lub lem, thiab tus naj npawb ntawm lem yuav tsum yog raws li tus naj npawb ntawm lem nyob rau hauv nruab nrab ntawm lub clamp, ces qhov kev nyeem ntawv {{ 1}}tus nqi qhia × Ntau yam / tag nrho qhov sib txawv × Tus lej hloov
4. Tom qab kev ntsuas tiav, qhov hloov pauv yuav tsum tau muab tso rau ntawm qhov siab tshaj plaws
5. Thaum ntsuas, ntsuas cov hlau yuav tsum tau muab tso rau hauv nruab nrab ntawm lub clamp thiab lub clamp yuav tsum kaw kom nruj kom txo tau qhov yuam kev.
Kev ceev faj rau digital clamp watches
1. Qhov voltage ntawm qhov ntsuas hluav taws xob yuav tsum qis dua qhov ntsuas hluav taws xob ntawm lub ntsuas ntsuas clamp
2. Thaum ntsuas qhov tam sim no ntawm cov kab hluav taws xob siab, nws yog ib qho tsim nyog yuav tsum hnav cov hnab looj tes insulating, khau, thiab sawv ntsug ntawm ib lub txaj insulating.
3. Lub puab tsaig yuav tsum tau kaw kom nruj thiab tsis tuaj yeem hloov nrog lub zog
Siv lub clamp ammeter los ntsuas qhov tam sim no ntawm ib qho winding ntawm lub cev muaj zog yog theem tam sim no, tab sis nws yuav ua rau muaj teeb meem hauv kev ntsuas qhov tseeb. Ob leeg txuas tag nrho peb khub ntawm winding hlau rau sab nraud; Tam sim no ntawm cov kab hluav taws xob yog ib txwm yog kab tam sim no; Nws yog ib qho nyuaj thiab impractical los xam lub hwj chim ntawm ib tug tej yam lub cev muaj zog. Lub zog qhov tseem ceeb yog qhov tsis paub tseeb, tshwj tsis yog lub ntsuas hluav taws xob tseem txuas nrog, tab sis nws yuav tsum tau muab sau tseg tias vim yog vim li cas thauj khoom, lub zog hloov pauv.
