Kev taw qhia luv luv thiab siv cov clamp ammeter
Nws yog ib nqi sau cia hais tias vim hais tias lub hauv paus ntsiab lus ntawm lub clamp ammeter yog siv lub hauv paus ntsiab lus ntawm lub transformer, seb lub hlau core yog kaw nruj nreem los yog seb puas muaj ib tug loj npaum li cas ntawm cov seem hlau nplaum muaj ib tug zoo kawg nkaus lub luag hauj lwm rau cov kev ntsuas. Thaum ntsuas qhov me me tam sim no, qhov ntsuas qhov yuam kev yuav nce ntxiv. . Lub sijhawm no, cov hlau ntsuas tuaj yeem raug mob ob peb zaug ntawm cov tub ntxhais hlau los hloov qhov sib piv tam sim no ntawm lub transformer kom nce qhov tam sim no.
Lub hauv paus ntsiab lus ntawm lub clamp ammeter yog ua raws li txoj hauv kev ua haujlwm ntawm tam sim no transformer. Thaum cov hlau tseem ceeb ntawm tus ciaj ntswj yog loosened thiab kaw, ib tug induced tam sim no yog generated nyob rau hauv lub thib ob winding raws li lub hauv paus ntsiab lus ntawm transformer, thiab lub pointer ntawm lub ammeter deflects, yog li qhia qhov ntsuas tus nqi ntawm tam sim no. Thaum lub clamp ammeter wrench yog tuav nruj, cov tub ntxhais hlau ntawm lub tam sim no transformer tuaj yeem qhib, thiab cov xaim ntawm cov ntsuas tam sim no nkag mus rau sab hauv lub puab tsaig raws li thawj winding ntawm tam sim no transformer.
Cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau thaum siv lub clamp ammeter:
Thaum soj ntsuam lub sijhawm ntawm lub moos, kev saib xyuas tshwj xeeb yuav tsum tau them rau kom qhov siab tshaj plaws nyob deb ntawm lub taub hau thiab qhov them nyiaj. Qhov kev ncua deb ntawm ib feem ntawm tib neeg lub cev thiab lub cev them nyiaj yuav tsum tsis txhob tsawg tshaj li tag nrho qhov ntev ntawm lub clamp meter.
Thaum ntsuas nyob rau hauv high-voltage Circuit Court, nws yog txwv tsis pub siv ib tug hlau los txuas lub clamp ammeter mus rau lwm lub 'meter' rau kev ntsuas. Thaum ntsuas qhov tam sim no ntawm txhua theem ntawm high-voltage cable, qhov kev ncua deb ntawm lub cable xaus yuav tsum ntau tshaj 300mm, thiab cov rwb thaiv tsev yuav tsum zoo, thiab kev ntsuas tsuas yog nqa tawm thaum nws pom tau tias yooj yim.
Thaum ntsuas qhov tam sim no ntawm cov hluav taws xob tsis tshua muaj hluav taws xob fusible fuses lossis kab rov tav txheej txheem qis-voltage busbars, fusible fuses lossis busbars ntawm txhua theem yuav tsum tau tiv thaiv thiab cais nrog cov ntaub ntawv insulating ua ntej ntsuas, thiaj li tsis ua rau luv luv Circuit Court ntawm theem.
Tom qab ntsuas lub clamp ammeter, rub lub hloov mus rau qhov siab tshaj plaws kom tsis txhob muaj kev sib tsoo overcurrent thaum siv tom ntej; thiab nws yuav tsum tau muab cia rau hauv chav qhuav
Nws yog nruj me ntsis txwv tsis pub ntsuas thaum ib theem ntawm lub cable yog grounded. Tiv thaiv kom tsis txhob muaj qhov tshwm sim hauv av tawg tawg vim qhov hluav taws xob qis ntawm lub taub hau cable thiab ua rau muaj kev phom sij rau tus kheej.
Thaum siv high-voltage clamp meter, yuav tsum tau them nyiaj mloog mus rau theem voltage ntawm lub clamp meter, thiab nws yog nruj me ntsis txwv tsis pub siv lub low-voltage clamp meter los ntsuas qhov tam sim no ntawm high-voltage circuit. Thaum ntsuas nrog high-voltage clamp meter, nws yuav tsum tau ua los ntawm ob tug neeg. Cov neeg ua haujlwm tsis ua haujlwm yuav tsum tau sau thawj hom ntawv ua haujlwm. Thaum ntsuas, lawv yuav tsum hnav cov hnab looj tes insulating, sawv ntsug ntawm cov ntaub thaiv npog, thiab tsis txhob kov lwm yam khoom siv los tiv thaiv luv luv los yog hauv av.
Yuav ua li cas siv clamp ammeter:
Ua ntej ntawm tag nrho cov, xaiv qhov voltage theem ntawm lub clamp ammeter, xyuas seb nws zoo li rwb thaiv tsev puas zoo, seb nws puas puas, seb lub pointer swings flexibly, seb lub puab tsaig yog xeb, thiab lwm yam. Kwv yees qhov ntsuas tam sim no raws li lub zog lub cev muaj zog. xaiv qhov ntau ntawm qhov ntsuas.
Lub puab tsaig ntawm lub clamp meter yuav tsum kaw kom nruj thaum ntsuas. Yog tias muaj suab nrov tom qab kaw, koj tuaj yeem qhib lub puab tsaig thiab rov ua dua. Yog tias lub suab nrov tseem tsis tuaj yeem raug tshem tawm, koj yuav tsum xyuas seb qhov sib txuas ntawm qhov sib nqus ntawm cov hlau nplaum puas yog du thiab huv, thiab so kom huv si yog tias muaj plua plav. .
Lub clamp meter tsuas tuaj yeem ntsuas qhov tam sim no ntawm ib theem xaim ntawm ib lub sijhawm, thiab cov xaim yuav tsum tau sim yuav tsum muab tso rau hauv nruab nrab ntawm lub qhov rais clamp, thiab cov xov hlau ntau theem tsis tuaj yeem clamped rau hauv lub qhov rais rau kev ntsuas.
Qhov hluav taws xob ntawm lub voj voog nyob rau hauv kev sim tsis tuaj yeem tshaj tus nqi cim ntawm lub ntsuas ntsuas, txwv tsis pub nws yuav yooj yim ua rau muaj kev sib tsoo hauv av lossis ua rau muaj kev phom sij rau hluav taws xob.
Ua ntej siv lub clamp ammeter, koj yuav tsum nyeem cov lus qhia kom zoo kom paub seb nws puas yog AC lossis AC-DC dual-purpose clamp meter.
Vim tias qhov tseeb qis ntawm lub clamp ammeter nws tus kheej, cov qauv hauv qab no tuaj yeem siv tau thaum ntsuas me me tam sim no: thawj cua cov hlau ntawm lub voj voog nyob rau hauv kev sim ob peb zaug, thiab tom qab ntawd muab tso rau hauv lub puab tsaig ntawm lub clamp meter rau kev ntsuas. Lub sijhawm no, tus nqi tam sim no qhia los ntawm clamp meter tsis yog tus nqi tiag tiag raug ntsuas. Qhov tseeb tam sim no yuav tsum yog qhov kev nyeem ntawv ntawm lub clamp meter muab faib los ntawm tus lej ntawm cov xov hlau.
Ntsuas qhov kev khiav hauj lwm tam sim no ntawm lub tawb-hom asynchronous lub cev muaj zog hauv kev ua haujlwm. Raws li qhov loj ntawm qhov tam sim no, nws tuaj yeem kuaj xyuas seb lub cev muaj zog puas ua haujlwm li qub, thiaj li ua kom lub cev muaj kev nyab xeeb thiab ua haujlwm ntev.
Thaum ntsuas, nws tuaj yeem ntsuas ib zaug rau txhua theem lossis ib zaug rau peb theem. Lub sijhawm no, tus lej ntawm lub 'meter' yuav tsum yog xoom (vim tias phasor sum ntawm peb theem tam sim no yog xoom). Thaum muaj ob theem xaim nyob rau hauv lub puab tsaig, lub meter yuav tso saib Tus nqi yog tus nqi tam sim no ntawm theem peb. Los ntawm kev ntsuas qhov tam sim no ntawm txhua theem, nws tuaj yeem txiav txim siab seb lub cev muaj zog yog overloaded (qhov ntsuas tam sim no tshaj qhov ntsuas tam sim no). Puas muaj teeb meem, uas yog, seb qhov peb-theem tam sim no tsis txaus siab tshaj qhov txwv ntawm 10 feem pua.
