Yuav siv li cas thiab ceev faj rau kev ntsuas clamp meters nrog cov neeg siv 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 rau hauv daim pib ua haujlwm thib ob thaum ntsuas. Lawv yuav tsum hnav cov hnab looj tes insulating thiab sawv ntawm cov ntaub qhwv insulating thaum ntsuas. Lawv yuav tsum tsis txhob kov lwm yam khoom siv los tiv thaiv luv luv lossis hauv av.
(2) Thaum soj ntsuam lub sij hawm ntawm lub 'meter', yuav tsum tau saib xyuas tshwj xeeb 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 luv luv Circuit Court ntawm theem.
(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 muab cia rau hauv chav qhuav.
