Kev ntsuas nrog hluav taws xob clamp meter siv thiab ceev faj
Clamp ammeter muab faib ua qhov siab thiab qis voltage ob hom, siv nyob rau hauv cov ntaub ntawv ntawm tsis dismantling txoj kab ncaj qha ntsuas qhov tam sim no nyob rau hauv txoj kab. Nws txoj kev siv yog raws li nram no:
(1) kev siv high-voltage clamp meter yuav tsum tau them sai sai rau qhov voltage theem ntawm lub clamp ammeter, yog nruj me ntsis txwv tsis pub siv tsawg-voltage clamp meter los ntsuas qhov tam sim no ntawm high-voltage circuit. Kev ntsuas nrog high-voltage clamp meter, yuav tsum tau ua los ntawm ob tus neeg, cov neeg ua haujlwm tsis yog lub luag haujlwm los ntsuas yuav tsum tau sau cov ** hom daim pib ua haujlwm, ntsuas yuav tsum hnav cov hnab looj tes insulated, sawv ntawm insulating mats, thiab yuav tsum tsis txhob kov. lwm yam khoom siv los tiv thaiv luv luv lossis hauv av.
(2) Saib xyuas lub sijhawm ntsuas lub sijhawm, ua tib zoo saib xyuas lub taub hau thiab qhov chaw them nyiaj ntawm ** nrug, qhov kev ncua deb ntawm ib feem ntawm tib neeg lub cev thiab lub cev them nyiaj yuav tsum tsis pub tsawg dua qhov ntev ntawm lub ntsuas clamp. .
(3) Thaum ntsuas ntawm lub high-voltage Circuit Court, nws yog txwv tsis pub siv ib tug hlau mus txuas rau lwm meter los ntawm lub clamp-on ammeter los ntsuas. Kev ntsuas ntawm high-voltage cable tam sim no ntawm txhua theem, qhov kev ncua deb ntawm lub cable taub hau kab yuav tsum ntau tshaj 300mm, thiab zoo rwb thaiv tsev, yuav tsum tau txiav txim siab yooj yim rau kev ntsuas ua ntej.
(4) Kev ntsuas qhov hluav taws xob qis fusible fuse lossis kab rov tav txheej txheem qis-voltage busbar tam sim no, yuav tsum tau ntsuas ua ntej cov theem ntawm fusible fuse lossis busbar nrog cov ntaub ntawv insulating los tiv thaiv kev sib cais, thiaj li tsis ua rau theem-rau-theem luv luv Circuit Court. .
(5) Kev ntsuas yog nruj me ntsis txwv tsis pub thaum ib theem ntawm cable yog grounded. Tiv thaiv qhov tshwm sim ntawm cov rwb thaiv tsev qis vim lub taub hau cable rau hauv av tawg tawg thiab ua rau muaj kev phom sij rau tus kheej.
(6) Clamp ammeter ntsuas tom qab qhov kawg ntawm kev hloov mus rau * ntau yam iav, thiaj li tsis txhob yuam kev overcurrent siv tom ntej; thiab yuav tsum tau khaws cia hauv chav qhuav
