Yuav siv li cas thiab xyuam xim rau lub clamp meter thaum ntsuas nrog ib tug hluav taws xob
Muaj ob hom clamp ammeters, high voltage thiab low voltage, uas yog siv los ntsuas qhov tam sim no hauv kab yam tsis muaj kev cuam tshuam cov kab. Yuav siv li cas:
(1) Thaum siv high-voltage clamp meter, them sai sai rau qhov voltage ntawm lub clamp ammeter. Nws yog txwv tsis pub siv lub ntsuas hluav taws xob tsawg-voltage 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 thiab sawv ntawm ib lub hnab insulating thaum ntsuas. Lawv yuav tsum tsis txhob kov lwm yam khoom siv kom tsis txhob luv luv Circuit Court lossis grounding.
(2) Thaum soj ntsuam lub sij hawm ntawm lub 'meter', tshwj xeeb yuav tsum tau them nyiaj 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 meter.
(3) Thaum ntsuas ntawm lub high-voltage Circuit Court, nws yog txwv tsis pub siv cov xov hlau los ntawm clamp-hom 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 taub hau cable yuav tsum yog ntau tshaj 300mm thiab cov rwb thaiv tsev yuav tsum zoo. Kev ntsuas tsuas yog ua tau thaum nws pom tau tias yooj yim.
(4) Thaum ntsuas qhov tam sim no ntawm cov hluav taws xob qis fusible fuses lossis kab rov tav txheej txheem qis-voltage busbars, txhua theem fusible fuse lossis busbar yuav tsum tau tiv thaiv thiab cais nrog cov ntaub ntawv insulating ua ntej ntsuas kom tsis txhob muaj kev cuam tshuam luv luv.
(5) Thaum ib theem ntawm cable yog grounded, kev ntsuas yog nruj me ntsis txwv. Tiv thaiv kom tsis txhob muaj qhov tshwm sim ntawm qhov tawg tawg vim qhov hluav taws xob qis ntawm lub taub hau cable, uas yuav ua rau muaj kev phom sij rau tus kheej.
(6) Tom qab kev ntsuas ntawm lub clamp ammeter tiav lawm, rub lub hloov mus rau qhov siab tshaj plaws kom tsis txhob muaj kev cuam tshuam tsis zoo rau lwm zaus nws siv; thiab nws yuav tsum tau khaws cia hauv chav qhuav.
Yuav siv cov digital clamp meter li cas:
1. Kho tshuab xoom yuav tsum tau ua ua ntej ntsuas;
2. Tom ntej no, koj yuav tsum xaiv qhov tsim nyog. Xaiv qhov loj ua ntej thiab tom qab ntawd qhov me me. Koj tuaj yeem kwv yees nws raws li daim ntawv teev npe ntawm cov khoom siv hluav taws xob;
3. Thaum siv qhov tsawg kawg nkaus rau kev ntsuas, kev nyeem ntawv yuav tsis pom tseeb. Nyob rau hauv rooj plaub no, nws yog ib qho tsim nyog yuav tsum tau cua cov hlau yuav tsum tau ntsuas ob peb lub lem, thiab tus naj npawb ntawm tig yuav tsum yog raws li tus naj npawb ntawm cov lem nyob rau hauv nruab nrab ntawm lub puab tsaig. Nyob rau hauv cov ntaub ntawv no Qhov kev nyeem ntawv yog: nyeem=qhia tus nqi × ntau / tag nrho sib txawv × tus naj npawb ntawm lem;
4. Thaum ntsuas, cov hlau yuav tsum ntsuas yuav tsum nyob hauv nruab nrab ntawm lub puab tsaig, thiab lub puab tsaig yuav tsum tau kaw kom nruj, uas tuaj yeem txo qhov yuam kev;
5. Thaum qhov ntsuas tau ua tiav, hloov lub installation mus rau qhov siab tshaj plaws.
