Yuav ua li cas kom raug siv Clamp Ammeter los ntsuas Load Tam sim no
1. Xaiv lub iav tsim nyog. Cov ntsiab cai ntawm kev xaiv cov ntaub ntawv yog:
(1) Thaum ntsuas qhov ntsuas tam sim no paub: xaiv lub iav uas loj dua qhov ntsuas tus nqi tab sis ze tshaj rau nws.
(2) Yog tias koj tsis paub qhov ntau ntawm qhov tam sim no yuav tsum tau sim: koj tuaj yeem ua ntej teeb tsa tam sim no mus rau qib siab tshaj plaws rau kev sim.
2. Tus neeg kuaj xyuas yuav tsum hnav hnab looj tes, muab lub ntsuas ntsuas ntawm qhov kawg ntawm lub tiaj tiaj, qhib lub puab tsaig, cia cov hlau hauv qab ntsuas nkag mus rau lub puab tsaig thiab tom qab ntawd kaw lub puab tsaig. Cov hlau nyob rau hauv kev sim yuav tsum nyob rau hauv nruab nrab ntawm qhov chaw nyob rau hauv lub puab tsaig.
3. Kev nyeem ntawv kom raug: Raws li cov iav siv, nyeem cov ntawv nyeem ntawm cov kab sib txuas.
4. Thaum ntsuas me me tam sim no, yog tias koj ntsuas ntawm lub iav qis tshaj plaws, lub kaum sab xis ntawm lub koob tseem me me (lub kaum sab xis deflection ntawm rab koob yog me me, uas txhais tau hais tias tus txheeb ze yuam kev ntawm nws qhov ntsuas yog loj), thiab Qhov qis tshaj ntawm cov iav ntawm lub 'meter' yog qis dua 10 feem pua ntawm tag nrho cov nqi teev, cia cov hlau yuav raug mob nyob ib ncig ntawm lub puab tsaig rau ob peb lem, thiab tom qab lub puab tsaig raug kaw, nyeem cov ntawv nyeem. Lub sijhawm no: tus nqi tam sim no ntawm cov xaim=nyeem ntawv / tus lej hloov (xws li cov lej hloov: pes tsawg cov xov hlau nyob hauv lub puab tsaig, suav nrog pes tsawg zaus).
5. Tom qab ntsuas qhov tam sim no loj, ua ntej ntsuas qhov me me tam sim no, lub puab tsaig yuav tsum qhib thiab kaw ob peb zaug rau demagnetization;
Kev siv cov clamp ammeter
(1) Cov teeb meem xav tau kev saib xyuas thaum siv clamp ammeter
① Kwv yees qhov loj me ntawm qhov ntsuas tam sim no ua ntej ntsuas, thiab xaiv qhov tsim nyog.
② Thaum ntsuas, cov xaim nqa tam sim no yuav tsum tau muab tso rau hauv nruab nrab ntawm lub puab tsaig kom tsis txhob muaj qhov yuam kev. Rau kev ntsuas ntawm cov hlau tsis tshua muaj tam sim no, txhawm rau txhim kho qhov tseeb, yog tias cov xwm txheej tso cai, koj tuaj yeem ua kom cov hlau nyob hauv kev sim ob peb zaug, thiab muab tso rau hauv lub puab tsaig rau kev ntsuas. Tus nqi tam sim no yog sib npaug ntawm kev nyeem cov ' meter ' muab faib los ntawm cov xov tooj ntawm cov hlau coils.
③ Yog tias muaj suab nrov thaum ntsuas, nws txhais tau hais tias lub puab tsaig tsis zoo nrog cov xov hlau. Koj tuaj yeem qhib thiab kaw lub puab tsaig dua. Yog tias tseem muaj suab nrov, koj tuaj yeem siv roj av los ntxuav lub puab tsaig ua ntej ntsuas.
(2) Kev ntsuas kev ua haujlwm
① AC zog ntsuas. Tig qhov hloov mus rau ACA1000A iav. Tawm ntawm qhov hloov mus rau qhov chaw so. Nias lub khawm kom qhib lub puab tsaig, tuav ib lub xaim, thiab nyeem tus nqi. Yog tias qhov kev nyeem ntawv tsawg dua 200A, tig mus rau ACA200A txhawm rau txhim kho qhov tseeb ntawm kev nyeem ntawv.
② AC thiab DC voltage ntsuas. Thaum ntsuas DC voltage, tig mus rau DCV1000; Thaum ntsuas AC voltage, tig qhov hloov mus rau ACV750V, thiab khaws lub hloov mus rau hauv lub xeev so. Txuas cov liab xeem coj mus rau "VΩ" davhlau ya nyob twg, qhov kev xeem dub coj mus rau "COM" davhlau ya nyob twg, ces txuas cov liab thiab dub xeem coj mus rau lub Circuit Court nyob rau hauv kev xeem nyob rau hauv parallel, thiab tus nqi nyeem ntawv yog qhov tseeb voltage ntawm lub Circuit Court. .
③ Kev ntsuas kev tiv thaiv. Tig qhov hloov mus rau qhov hluav taws xob tsis kam ntawm qhov tsim nyog. Tawm ntawm qhov hloov mus rau qhov chaw so. Cov hlau kuaj liab txuas nrog "VΩ" davhlau ya nyob twg, thiab cov hlau kuaj dub txuas nrog lub davhlau ya nyob twg "COM". Txuas qhov kev xeem liab thiab dub ua rau ob qho kawg ntawm qhov ntsuas tsis kam, thiab tus nqi nyeem ntawv yog qhov tseeb tsis kam ntawm qhov ntsuas tsis kam.
Nco tseg: Thaum ntsuas kev tiv thaiv hauv online, cov kab yuav tsum raug kaw thiab lub capacitor txuas nrog lub resistor yuav tsum raug tso tawm.
④ Kev ntsuas txuas ntxiv. Tig qhov hloov mus rau 200Ω, txuas cov kev xeem liab coj mus rau "VΩ" davhlau ya nyob twg, thiab qhov kev sim dub coj mus rau "COM" davhlau ya nyob twg. Yog hais tias lub buzzer nyob rau hauv lub 'meter' suab, nws txhais tau hais tias qhov kev tiv thaiv ntawm cov liab thiab dub xeem leads yog tsawg tshaj li 50 ± 2.5Ω.
