Yuav ua li cas siv ib qho xau ntxab tes taw qhia tam sim no
Lub tofile tam sim no nthuav qhia hloov dua siab tshiab, kev hloov dua siab tshiab, AC / DC hloov dua siab tshiab, kev hloov kho cov khoom siv. Ib txhia tseem tau tiv thaiv dhau los, lub suab thiab lub teeb pom kev zoo, thiab lawv cov khoom siv hluav taws xob tau muab faib ua cov analog thiab digital hom. Raws li UL cov qauv hauv Tebchaws Meskas, kev so tam sim no yog hais txog qhov tam sim no uas tuaj yeem ua tau los ntawm cov khoom siv hauv tsev, suav nrog capactrate conchaning tam sim no. Cov to tam sim no suav nrog ob ntu, ib qho yog qhov ua rau I1 tam sim no los ntawm cov rwb thaiv tsev tsis kam; Lwm qhov yog los ntawm kev xa khoom Tus muab faib tau cov captibration tam sim no nce nrog ntau zaus, yog li cov xau dej nce nrog qhov nce ntawm lub zog zaus. Piv txwv li, thaum siv lub zog thyristor, nws cov harmonic Cheebtsam nce ntxiv cov toast tam sim no.
Yog tias qhov kev ntsuam xyuas yog nyob ntawm kev ua haujlwm rwb thaiv tsev ntawm lub ntiaj teb (lossis cov khoom siv hluav taws xob sab nraud) los ntawm cov khoom siv insulting rau hauv lub ntiaj teb Ntev ntev tuaj yeem ua rau muaj peev xwm muab tau muaj peev xwm muab tau muaj peev xwm loj dua thiab ua kom muaj xau dej tam sim no, uas yuav tsum tau sau tshwj xeeb hauv cov cheeb tsam.
Kev ceev faj rau to furnage clampage ammeter:
Lub hauv paus ntsiab lus ntawm kev ntsuas xau xau tam sim no yog qhov zoo tib yam li ntsuas rwb thaiv tsev tsis kam. Kev ntsuas rwb thaiv tsev tsis kam yog qhov tseeb ib hom tople to tam sim no, tab sis nws tau qhia nyob rau hauv daim ntawv ntawm kev tiv thaiv. Txawm li cas los xij, ntsuas ntsuas ntawm kev xau tam sim no siv tau siv voltage, yog li cov khoom sib xyaw muaj xws li muaj peev xwm tam sim no.
2. Lub sijhawm tiv thaiv voltage, txhawm rau tiv thaiv cov khoom kuaj thiab ntsuas kom tau cov khoom siv cov kev ntsuas (cov hluav taws xob cov hluav taws xob lub zog yam tsis muaj kev ua phem. Qhov tam sim no feem ntau hu ua toast tam sim no, tab sis cov ntsiab cai no tsuas yog siv nyob rau hauv cov xwm txheej tshwj xeeb uas tau hais los saud. Thov mloog rau qhov sib txawv.
3. Tam sim no yog qhov tam sim no yog qhov tam sim no uas ntws los ntawm cov rwb thaiv tsev feem ntawm hluav taws xob lossis khoom siv yam tsis muaj kev ua txhaum lossis siv voltage. Yog li ntawd, nws yog ib qho ntawm cov ntsuas tseem ceeb los ntsuas cov rwb thaiv tsev kev ua tau zoo ntawm cov khoom siv hluav taws xob thiab yog qhov ua tau zoo tshaj plaws ntawm cov khoom lag luam.
4. Kev sim ua haujlwm tam sim no tau siv los ntsuas cov toaster muab tam sim no los ntawm rwb thaiv tsev lossis faib cov tsis cuam tshuam nrog kev ua haujlwm. Nws cov tswv yim impedance simulates lub impedance ntawm tib neeg lub cev.
