Yuav nyeem li cas thaum clamp ammeter ntsuas tam sim no
1. Xaiv cov iav thiab ntau yam. Tig lub ntsuas hluav taws xob mus rau txoj hauj lwm ntawm DC tam sim no "mA", thiab xaiv qhov tseeb raws li qhov ntsuas tam sim no. Yog tias qhov tam sim no tsis paub, txhawm rau kom tsis txhob muaj qhov tam sim no loj dhau thiab dhau qhov ntau, koj tuaj yeem ua ntej tso DC tam sim no ntawm lub iav siab tshaj plaws rau kev sim. Yog tias qhov ntau ntau dhau lawm, ces txo qhov ntau kom txog thaum qhov ntau yam haum.
2. Txuas lub voj voog hauv series. Thaum lub multimeter ntsuas qhov tam sim no, cov hlau lead xeem yuav tsum tau txuas nrog tam sim no nyob rau hauv series, thiab cov hlau kuaj liab txuas nrog lub siab muaj peev xwm kawg ntawm Circuit Court, thiab cov hlau lead kuaj dub txuas nrog rau qhov tsawg kawg nkaus ntawm qhov tam sim no. .
3. Kev nyeem ntawv:
(1) Xaiv cov kab teev kom raug rau kev nyeem ntawv.
(2) Hloov tus nqi tam sim no: Tus nqi tam sim no=tus naj npawb ntawm cov nplai taw qhia los ntawm tus taw tes × qhov loj ntawm qhov ntau / tus nqi siab tshaj plaws ntawm cov nplai xaiv.
Qhov thib ob, kev siv cov clamp ammeter yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:
1. Thaum ntsuas ntawm high-voltage Circuit Court, nws yog txwv tsis pub siv cov xov hlau los txuas lub clamp ammeter 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 saib xyuas 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 cov hluav taws xob qis fusible fuses lossis kab rov tav txheej txheem qis-voltage busbars, lub fusible fuses lossis busbars ntawm txhua theem yuav tsum tau tiv thaiv thiab cais nrog cov ntaub ntawv insulating ua ntej ntsuas kom tsis txhob muaj kev cuam tshuam luv luv.
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 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 tus kheej kev nyab xeeb los ntawm kev raug punctured thiab tawg vim tsis muaj rwb thaiv tsev 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.
