Siv lub clamp ammeter los xyuas qhov tsis tshua muaj hluav taws xob xau thiab hluav taws xob tub sab
1, los txiav txim seb qhov seem tam sim no tus tiv thaiv nws tus kheej puas muaj teeb meem
Cov txheej txheem yog: nyob rau hauv lub transformer tis, kev tswj ntawm low-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, nws ua pov thawj tias cov residual. tam sim no kev tiv thaiv kev tiv thaiv yog qhov zoo. Txwv tsis pub, qhov seem tam sim no tus tiv thaiv yuav tsum tau kho dua thiab hloov.
2, xyuas seb qhov twg theem ntawm cov 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 cov 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 them theem kab los txiav txim qhov chaw ntawm lub leak. Txhawm rau txhim kho kev ua haujlwm tau zoo, txoj haujlwm nce qib tuaj yeem xaiv tau nyob rau hauv nruab nrab ntawm txoj kab, los ntawm kev tshawb pom ntawm cov khoom xau hauv thawj ib nrab ntawm kab lossis thib ob ib nrab, thiab tom qab ntawd mus rau qhov xav tias qhov xau ntawm cov kab seem nrhiav pom. Thiab yog li ntawd, kom nqaim qhov nrhiav kom tau ntau yam. * Tom qab ntawd, 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 cov neeg siv cov kab txuas txuas nrog rau theem kab hauv qhov ntau yog kuaj (txawm hauv av lossis tib lub sijhawm thaum cov insulator raug kuaj), txhawm rau txiav txim siab qhov tshwj xeeb ntawm cov dej 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 tau 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 yog: tus neeg siv lub hwj chim muab tso rau hauv lub tsev kab nrog ib tug clamp-on ammeter los ntsuas tam sim no ntws, thaum tus neeg siv lub hwj chim khoom, teeb thiab teeb ib tug los ntawm ib tug mus rau hauv lub tawm, los ntawm saib lub clamp-on ammeter los xyuas cov kev hloov hauv leakage tam sim no los nrhiav cov khoom xau thiab cov teeb thiab teeb ci. Yog tias tag nrho cov khoom siv teeb pom kev zoo thiab teeb pom kev zoo, lossis 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 qis qis, yuav tsum tau daws. 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.
