Kev ceev faj rau kev ntsuas tam sim no nrog lub clamp-on meter
Clamp hom ammeters tau muab faib ua qhov siab thiab tsis tshua muaj hluav taws xob, siv ncaj qha ntsuas qhov tam sim no hauv Circuit Court yam tsis muaj kev cuam tshuam hauv Circuit Court. 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. Nws yog txwv tsis pub siv lub ntsuas hluav taws xob tsawg-voltage los ntsuas qhov tam sim no ntawm high-voltage circuit. Thaum siv lub high-voltage clamp meter rau kev ntsuas, nws yuav tsum tau ua los ntawm ob tug neeg. Cov neeg ua haujlwm tsis ua haujlwm yuav tsum tau ua daim ntawv tso cai ua haujlwm thib ob. Thaum ntsuas, lawv yuav tsum hnav cov hnab looj tes insulated, sawv ntawm cov ntaub thaiv npog, thiab tsis txhob kov lwm yam khoom siv los tiv thaiv luv luv los yog hauv av.
(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 them nyiaj. Qhov kev ncua deb ntawm ib feem ntawm tib neeg lub cev thiab qhov them nyiaj yuav tsum tsis txhob tsawg tshaj li qhov ntev ntawm lub clamp saib.
(3) Thaum ntsuas ntawm high-voltage Circuit Court, nws yog txwv tsis pub txuas cov xov hlau los ntawm lub clamp ammeter mus rau lwm lub 'meter' rau kev ntsuas. Thaum ntsuas qhov tam sim no ntawm txhua theem ntawm high-voltage cables, qhov kev ncua deb ntawm cable taub hau yuav tsum yog tsawg kawg yog 300 hli, thiab cov rwb thaiv tsev yuav tsum zoo. Nws tsuas yog ua tau thaum nws pom tau tias yooj yim rau kev ntsuas.
(4) Thaum ntsuas qhov tam sim no ntawm cov hluav taws xob tsis tshua muaj hluav taws xob fusible los yog kab rov tav txheej txheem qis-voltage busbars, txhua theem ntawm fusible fuse los yog busbar yuav tsum tau tiv thaiv thiab cais cov ntaub ntawv rwb thaiv tsev ua ntej ntsuas kom tsis txhob ua rau theem luv luv Circuit Court.
(5) Nws yog nruj me ntsis txwv tsis pub ntsuas thaum ib theem ntawm cable yog grounded. Txhawm rau tiv thaiv kev tawg hauv av thiab tawg los ntawm kev rwb thaiv tsev qis ntawm lub taub hau cable, uas yuav ua rau muaj kev phom sij rau tus kheej.
(6) Tom qab qhov kev ntsuas clamp ammeter tiav, tig qhov hloov mus rau qhov siab tshaj plaws kom tsis txhob overcurrent thaum siv tom ntej; Thiab yuav tsum tau muab cia rau hauv tsev hauv qhov chaw qhuav.
