Tshawb xyuas cov kab hluav taws xob qis qis thiab hluav taws xob tub sab nrog Clamp Ammeter
1, txiav txim qhov seem tam sim no tus tiv thaiv nws tus kheej seb puas muaj teeb meem
Cov txheej txheem yog: nyob rau hauv lub transformer tis, kev tswj ntawm tsawg-voltage kab AC contactor tawm ntawm theem kab nyob rau sab ntawm lub fuse yog disconnected, yog hais tias tus residual tam sim no tus tiv thaiv yuav muab tso rau hauv lub lag luam ib txwm nyob rau lub sij hawm no, nws proves tias qhov seem tam sim no ua haujlwm tiv thaiv zoo. Txwv tsis pub, qhov seem tam sim no tus tiv thaiv yuav tsum tau kho dua thiab hloov.
2, xyuas seb cov theem twg yog theem kab xau
Cov txheej txheem yog: nyob rau hauv lub tis transformer, kev tswj ntawm low-voltage kab AC contactor qhov hluav taws xob sab ntawm lub nruab nrab kab disconnected, thiab ces tau raug tshem tawm los ntawm lub fuse core ntsia nyob rau hauv ib tug ntawm cov theem, nrog ib tug clamp-on ammeter los ntsuas. theem, qhov ntsuas tam sim no yog qhov xau tam sim no ntawm theem. Raws li tib txoj kev nyob rau hauv lem ntsuas qhov to tam sim no ntawm cov seem to.
Txhawm rau tiv thaiv qhov muaj nyob ntawm theem grounding ntawm kab (xws li ib txoj kab ntawm cov neeg siv hauv av txoj kev ntawm hluav taws xob tub sab, thiab lwm yam) tshwm sim loj tam sim no kev puas tsuaj rau lub twj paj nruag, qhov kev tshawb pom ntawm thawj clamp-on ammeter block ntawm lub loj tam sim no thaiv; yog tias tus nqi nrhiav tau tsawg heev, thiab tom qab ntawd lub clamp-on ammeter block hloov mus rau milliampere thaiv kev tshawb nrhiav.
3, tom qab txiav txim siab qhov muaj nyob ntawm cov kab xau, txiav txim siab qhov chaw ntawm qhov xau
Txoj kev yog: nyob rau hauv lub tis transformer, cov theem kab yuav tsum tau soj ntsuam ntxig fuse core, nruab nrab kab thiab cov seem ob theem ntawm lub fuse yog disconnected, boarding ncej nrog ib tug clamp-on ammeter mus ntes tus them theem kab los txiav txim qhov chaw ntawm. qhov to. Txhawm rau txhim kho kev ua haujlwm tau zoo, txoj haujlwm nce qib tuaj yeem xaiv nyob rau hauv nruab nrab ntawm txoj kab, los ntawm kev tshawb pom cov khoom xau nyob rau hauv thawj ib nrab ntawm txoj kab lossis thib ob ntawm kab, thiab tom qab ntawd mus rau qhov xav tias xau ntawm kab. kuaj pom. Thiab yog li ntawd, kom nqaim qhov nrhiav kom tau ntau yam. Thaum kawg, lub insulator ntawm tus ncej ntawm theem kab nyob rau hauv qhov me me tau txiav txim siab yog kuaj, thiab cov theem kab ntawm tus neeg siv khoom txoj kab txuas txuas nrog rau theem kab nyob rau hauv qhov ntau yog sim (uas tuaj yeem ua rau hauv av lossis tib yam. lub sij hawm thaum lub insulator raug kuaj), txhawm rau txiav txim siab qhov tshwj xeeb ntawm cov xau.
Nyob rau hauv cov ntaub ntawv ntawm tsawg-voltage kab fais fab mov, kuj yuav raug txheeb xyuas nyob rau hauv lub Scope ntawm kev poob siab ntawm cov neeg siv tsawg-voltage txuas nrog tsev neeg kab nrog ib tug clamp-on ammeter rau nrhiav kom tau. Kev kuaj pom, cov neeg siv ib theem ntawm cov kab theem thiab cov kab nruab nrab yuav tsum muab tso rau hauv lub puab tsaig ntawm lub clamp-on ammeter tib lub sijhawm, cov neeg siv hluav taws xob peb theem ntawm peb theem kab thiab cov kab nruab nrab yuav tsum tau muab tso rau hauv. lub puab tsaig tib lub sijhawm. Yog tias tsis muaj qhov txhaum cai, qhov load tam sim no flux ntawm theem thiab xoom, clamp ammeter qhia kuj yog xoom; xws li to tam sim no, clamp ammeter tuaj yeem ntes tam sim no to.
4, xyuas cov neeg siv cov kab thiab cov khoom siv nrog los yog tsis muaj to
Txoj kev: tus neeg siv lub zog xa mus rau hauv lub tsev kab nrog lub clamp-on ammeter los ntsuas qhov ntws tawm tam sim no, thaum tus neeg siv khoom siv hluav taws xob, teeb thiab teeb ci ib qho los ntawm ib qho mus rau hauv kev tawm, los ntawm kev saib lub clamp-on ammeter kom pom cov kev hloov hauv cov dej xau tam sim no txhawm rau nrhiav cov khoom siv hluav taws xob thiab cov teeb ci thiab teeb ci. Yog tias tag nrho cov khoom siv teeb thiab teeb pom kev zoo, los yog muaj cov khoom xau tau raug tshem tawm, tab sis lub clamp-on ammeter qhia tau hais tias tus neeg siv tseem muaj cov xau tam sim no, nws yuav yog tus neeg siv cov kab hluav taws xob tsawg tsawg, yuav tsum yog. dealt nrog rau ntawm rooj plaub ntawm rooj plaub. Rau qhov ua ntej faus cov kav dej xau qhov txhaum, tsuas yog tuaj yeem hloov txoj kab lossis rov ua dua ntawm txoj kev kho.
