Yuav siv li cas thiab ceev faj rau kev ntsuas hluav taws xob ntsuas clamp meters
(1) Thaum siv high-voltage clamp meter, xyuam xim rau qib voltage ntawm lub clamp meter. Nws yog nruj me ntsis 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, ob tus neeg yuav tsum tau ua haujlwm. Cov neeg ua haujlwm tsis ua haujlwm yuav tsum tau sau daim pib ua haujlwm thib ob. Thaum ntsuas, lawv yuav tsum hnav cov hnab looj tes insulating thiab sawv ntawm cov ntaub qhwv insulating. Lawv yuav tsum tsis txhob kov lwm yam khoom siv los tiv thaiv luv luv los yog hauv av.
(2) Thaum soj ntsuam lub sijhawm ntsuas lub sijhawm, ua tib zoo saib xyuas 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 tag nrho qhov ntev ntawm lub clamp meter.
(3) Thaum ntsuas ntawm qhov hluav taws xob hluav taws xob siab, nws yog txwv tsis pub siv cov xaim txuas mus rau lwm lub 'meter' los ntawm lub ntsuas ntsuas clamp. 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 qhov hluav taws xob qis fusible fuse lossis kab rov tav txheej txheem qis-voltage busbar, 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 ua rau theem-rau-theem luv. circuits.
(5) Thaum ib theem ntawm lub cable yog grounded, ntsuas yog nruj me ntsis txwv tsis pub. Qhov no yog txhawm rau tiv thaiv lub taub hau cable los ntawm kev tawg hauv av thiab tawg vim tsis muaj qhov rwb thaiv tsev, uas yuav ua rau muaj kev phom sij rau tus kheej.
(6) Tom qab ntsuas, lub clamp ammeter yuav tsum tau hloov mus rau qhov siab tshaj plaws kom tsis txhob muaj kev sib tsoo overcurrent thaum siv tom ntej; nws yuav tsum tau muab cia rau hauv ib chav qhuav.
