Thaum txhim kho lub cev muaj zog, nws puas yuav tsum tau siv lub clamp ammeter?
Lub clamp ammeter yog siv los ntsuas qhov tseeb tam sim no ntawm ib theem kab, vim hais tias lub clamp ammeter yog sib npaug rau CT ntawm qhov qhib Circuit Court ntawm thawj winding, thiab tam sim no kuaj pom ib zaug yuav tshwm nyob rau hauv qhov kev xav thib ob, tsis hais txog kev sib txuas. ntawm peb-theem lub cev muaj zog.
Thawj kauj ruam yog ntsuas cov theem sib cais, uas tuaj yeem ntsuas qhov ntsuas hluav taws xob ncaj qha ntawm theem nrab ntawm qhov hluav taws xob hloov hluav taws xob (txoj kev yog tib yam li saum toj no) lossis ncaj qha ntsuas theem voltage (qhov kawg ntawm lub ntsuas hluav taws xob). Txawm li cas los xij, nws yog ib qho tsim nyog los ntxig ib qho kev sojntsuam thiab xaiv qhov ntsuas qhov tsim nyog. Nws "bayonet" tsuas yog ib qho tshwj xeeb clamp meter rau ntsuas AC tam sim no. Ua kom tus pointer nyob rau sab xis, thiab siv tib txoj kev raws li cov multimeter sib xyaw kom maj mam hloov ntawm qib siab mus rau qib qis thaum tsis paub qhov voltage;
Qhov thib ob kauj ruam yog ntsuas qhov voltage nyob rau hauv parallel nrog lub sojntsuam. Lub clamp meter tsis tuaj yeem ncaj qha "clamp" qhov voltage nrog nws txuas nrog multimeter thiab kho qhov hloov pauv mus rau qhov tsim nyog.
Kev siv cov digital clamp meter
1. Kev kho tshuab xoom yuav tsum tau ua ntej ntsuas.
2. Xaiv qhov tsim nyog, ua ntej xaiv ntau yam loj, tom qab ntawd xaiv ib qho me me los yog saib cov npe ntawm cov nqi kwv yees.
3. Thaum siv qhov ntsuas qhov tsawg kawg nkaus, thaum qhov kev nyeem ntawv tsis pom tseeb, cov hlau ntsuas tuaj yeem raug mob ob peb zaug, thiab tus naj npawb ntawm cov lem yuav tsum yog raws li tus naj npawb ntawm tig ntawm lub puab tsaig, yog li kev nyeem ntawv {{ 1}} qhia tus nqi × ntau yam / tag nrho qhov sib txawv × tus lej ntawm qhov hloov.
4. Tom qab ntsuas, muab qhov hloov pauv hloov mus rau qhov siab tshaj plaws.
5. Thaum ntsuas, cov hlau ntsuas yuav tsum nyob hauv nruab nrab ntawm lub puab tsaig, thiab lub puab tsaig yuav tsum raug kaw kom txo qhov yuam kev.
Cov teeb meem xav tau kev saib xyuas ntawm digital clip-on saib
1. Qhov voltage ntawm cov kab kuaj yuav tsum qis dua qhov ntsuas hluav taws xob ntawm lub ntsuas ntsuas clamp.
2. Thaum ntsuas cov kab hluav taws xob high-voltage tam sim no, hnav cov hnab looj tes insulating, khau thiab sawv ntsug ntawm insulating lev.
3. Lub puab tsaig yuav tsum raug kaw kom nruj, thiab qhov ntau yam tsis tuaj yeem hloov tau los ntawm hluav taws xob.
Kev ntsuas qhov tam sim no ntawm ib qho winding ntawm lub cev muaj zog nrog lub clamp ammeter yog theem tam sim no, tab sis nws yuav ua teeb meem rau qhov ntsuas qhov tseeb, lossis tag nrho peb khub ntawm cov xov hlau winding yuav raug txuas nrog 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 zog ntawm lub cev muaj zog. Lub hwj chim factor yog qhov tsis paub tseeb. Tshwj tsis yog tias koj txuas lub rooj fais fab fais fab, koj yuav tsum paub tias lub hwj chim yuav hloov nrog lub load.
