Clamp meter siv thiab saib xyuas qhov teeb meem
Clamp ammeter muab faib ua qhov siab thiab qis voltage ob hom, siv nyob rau hauv cov ntaub ntawv ntawm tsis dismantling 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 low-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, kev ntsuas cov neeg ua haujlwm tsis yog lub luag haujlwm yuav tsum tau sau daim pib ua haujlwm thib ob, kev ntsuas yuav tsum hnav cov hnab looj tes insulated, sawv ntawm insulating mats, yuav tsum tsis txhob kov lwm yam khoom siv los tiv thaiv luv luv- circuit lubhauv av.
2, soj ntsuam lub sij hawm, them tshwj xeeb mloog mus kom lub taub hau thiab cov nqi sector ntawm lubkev nyab xeebntawm lub sijhawm nruab nrab ntawm ib feem ntawm tib neeg lub cev thiab lub cev them nyiaj yuav tsum tsis pub tsawg tshaj li tag nrho qhov ntev ntawm lub clamp meter.
3, nyob rau hauv high-voltage Circuit Court ntsuas, txwv tsis pub siv cov xov hlau los ntawm lub clamp-on ammeter lwm meter ntsuas. Kev ntsuas ntawm high-voltage cable tam sim no ntawm txhua theem, lub cable headline ncua sij hawm yuav tsum yog ntau tshaj 300mm, thiab zoo rwb thaiv tsev, yuav tsum xav tias qhov ntsuas yog yooj yim, ua ntej mus.
4, ntsuas tsis tshua muaj hluav taws xob fusible fuse lossis kab rov tav teeb tsa tsis tshua muaj hluav taws xob tam sim no, yuav tsum ntsuas ua ntej theem fusible fuse lossis tsheb npav nrog cov ntaub ntawv insulating los tiv thaiv kev sib cais, thiaj li tsis ua rau luv luv Circuit Court ntawm theem.
5, thaum lub cable muaj ib theem grounded, nws yog nruj me ntsis txwv tsis pub ntsuas. Tiv thaiv qhov tshwm sim ntawm cov rwb thaiv tsev qis vim yog 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 rub mus rau qhov siab tshaj plaws ntau yam iav, thiaj li tsis txhob yuam kev overcurrent siv tom ntej; thiab yuav tsum tau khaws cia hauv chav qhuav!
