Yuav ua li cas siv lub clamp meter thiab ceev faj
Clamp ammeters tau muab faib ua qhov siab thiab tsis tshua muaj hluav taws xob, uas yog siv los ntsuas qhov tam sim no hauv kab yam tsis muaj kev cuam tshuam cov kab. Nws txoj kev siv yog raws li nram no:
(1) Thaum siv high-voltage clamp meter, yuav tsum tau them nyiaj mloog mus rau theem voltage ntawm lub 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.
(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 meter.
(3) Thaum ntsuas ntawm lub high-voltage Circuit Court, nws yog txwv tsis pub siv cov xov 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.
(4) Thaum ntsuas qhov tam sim no ntawm qhov 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 luv luv ntawm cov theem.
(5) Nws yog nruj me ntsis txwv tsis pub ntsuas thaum ib theem ntawm cable yog grounded. 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.
(6) Tom qab ntsuas ntawm lub clamp ammeter, rub lub hloov mus rau qhov chaw txwv kom tsis txhob muaj kev sib tsoo overcurrent thaum siv tom ntej; thiab nws yuav tsum tau muab cia rau hauv chav qhuav.
