Yuav ua li cas siv clamp ammeter kom raug
1. 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 rusted, thiab lwm yam. Kwv yees qhov ntsuas tam sim no raws li qhov. lub cev muaj zog los xaiv qhov ntau ntawm lub 'meter'.
2. 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.
3. Vim yog qhov tsis tshua muaj siab ntawm clamp ammeter nws tus kheej, cov qauv hauv qab no tuaj yeem siv thaum ntsuas qhov 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.
4. 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 koom ua ke ntawm cov hlau nplaum puas yog du thiab huv. So huv.
5. 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 kuaj xyuas 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.
6. Qhov hluav taws xob ntawm qhov ntsuas hluav taws xob 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.
7. Ntsuas qhov ua haujlwm 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.
8. Thaum ntsuas, koj 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 hauv lub puab tsaig, lub 'meter' yuav tsum yog xoom. Tus nqi tso tawm rau sab saud 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). Seb puas muaj teeb meem nrog lub hwj chim mov voltage, uas yog, seb qhov peb-theem tam sim no tsis txaus siab tshaj qhov txwv ntawm 10 feem pua.
9. Ua ntej ntsuas nrog lub ntsuas ntsuas clamp, koj yuav tsum xub ntsuas qhov loj ntawm qhov ntsuas tam sim no, thiab tom qab ntawd txiav txim siab seb yuav siv qhov twg. Yog tias nws tsis tuaj yeem kwv yees, koj tuaj yeem ua ntej siv cov ntaub ntawv ntau tshaj plaws thiab tom qab ntawd hloov nws mus rau ib qho me me kom tau txais kev nyeem ntawv tseeb. Nws tsis tuaj yeem siv lub iav qis tam sim no los ntsuas cov dej ntws loj. tiv thaiv kev puas tsuaj rau lub 'meter'.
Cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau thaum siv lub clamp ammeter:
1. Thaum ntsuas ntawm lub high-voltage Circuit Court, nws yog txwv tsis pub siv cov xov hlau los txuas lub clamp ammeter mus rau lub ntsuas 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.
2. Thaum soj ntsuam lub sijhawm ntawm lub moos, yuav tsum tau them nyiaj tshwj xeeb rau kev tswj kom muaj kev nyab xeeb ntawm lub taub hau thiab qhov chaw nyob. Qhov kev ncua deb ntawm ib feem ntawm tib neeg lub cev thiab lub cev nyob yuav tsum tsis txhob tsawg tshaj li qhov ntev ntawm lub clamp saib.
3. Thaum ntsuas qhov tam sim no ntawm low-voltage fusible fuses lossis horizontally teem low-voltage busbars, lub fusible fuses los yog busbars ntawm txhua theem yuav tsum tau tiv thaiv thiab cais nrog insulating cov ntaub ntawv ua ntej ntsuas kom tsis txhob interphase luv luv Circuit Court.
4. Ua tib zoo saib xyuas qhov voltage ntawm lub clamp ammeter thaum siv lub high-voltage clamp ammeter, 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 rau hauv daim pib ua haujlwm thib ob thaum ntsuas. Lawv yuav tsum hnav cov hnab looj tes insulating thaum ntsuas, sawv ntawm cov ntaub pua tsev insulating, thiab tsis txhob kov lwm yam khoom siv los tiv thaiv luv luv lossis hauv av.
5. Rub lub hloov mus rau qhov siab tshaj plaws tom qab ntsuas lub clamp ammeter kom tsis txhob muaj kev sib tsoo overcurrent thaum siv tom ntej; thiab nws yuav tsum tau muab cia rau hauv chav qhuav
6. Thaum ib theem ntawm lub cable yog grounded, nws yog nruj me ntsis txwv tsis pub ntsuas. Tiv thaiv kev nyab xeeb ntawm tus kheej los ntawm kev raug punctured thiab tawg vim qhov hluav taws xob qis ntawm lub taub hau cable.
7. Thaum lub ntsuas ntsuas ntsuas ntsuas, qhov tam sim no ntawm cov xaim nyob ze yuav cuam tshuam rau nws, yog li nws tseem yuav tsum tau ua tib zoo saib xyuas qhov sib npaug ntawm cov xov hlau peb-theem.
8. Tsis txhob ua haujlwm nrog hluav taws xob thaum kho kom tsis txhob muaj hluav taws xob poob.
