Kev sib tham luv luv ntawm qhov teeb meem ntawm kev xau thiab hluav taws xob tub sab nyiag nrog clamp ammeter
Hais txog kev siv lub clamp ammeter, siv lub clamp ammeter los xyuas seb puas muaj cov xau hauv cov kab hluav taws xob tsawg thiab seb puas muaj cov xau hauv kab. Cov haujlwm tseem ceeb suav nrog ntsuas cov dej xau tam sim no, txiav txim siab qhov chaw ntawm cov dej xau, thiab kuaj xyuas seb puas muaj cov dej xau hauv cov neeg siv cov khoom siv sab hauv thiab cov khoom siv, thiab lwm yam.
Clamp ammeter txhawm rau txheeb xyuas cov teeb meem xau thiab hluav taws xob tub sab nyiag
1. Txiav txim siab seb tus tiv thaiv kev tiv thaiv qhov seem seem puas zoo li qub
Nyob rau ntawm lub transformer faib, disconnect lub fuse ntawm theem kab ntawm lub qhov hluav taws xob sab ntawm AC contactor uas tswj cov kab hluav taws xob tsawg. Yog tias cov khoom tiv thaiv seem tam sim no tuaj yeem muab tso rau hauv kev ua haujlwm ib txwm nyob rau lub sijhawm no, nws txhais tau hais tias qhov seem tam sim no tus tiv thaiv yog qhov zoo; txwv tsis pub, qhov seem tam sim no tus tiv thaiv yuav tsum tau tshuaj xyuas thiab hloov.
2. Ntsuas cov dej ntws tam sim no
Ntawm lub tshuab hluav taws xob faib hluav taws xob, tshem tawm cov xaim nruab nrab ntawm qhov hluav taws xob sab ntawm AC contactor uas tswj cov kab hluav taws xob tsawg. Tom qab ntawd nruab lub fuse core tshem tawm ntawm ib qho ntawm cov theem thiab ntsuas theem nrog lub clamp ammeter. Qhov ntsuas tam sim no yog qhov xau tam sim no ntawm theem.
Thaum kawg, raws li tib txoj kev, ntsuas qhov xau tam sim no ntawm cov seem xau theem nyob rau hauv ib ntus.
Txhawm rau tiv thaiv cov theem xaim los ntawm kev ua hauv av ntawm txoj kab thiab ua rau tam sim no loj ua rau kev puas tsuaj rau lub ntsuas, lub clamp ammeter yuav tsum muab tso rau ntawm qhov loj tam sim no thaiv thaum kuaj; yog tias qhov kuaj pom tam sim no me me, maj mam txo cov iav.
3. Txheeb xyuas qhov chaw ntawm cov dej xau
Tom qab txiav txim siab txog theem kab nrog kev xau, koj tuaj yeem txiav txim siab ntxiv qhov chaw ntawm qhov to.
(1) Tshawb xyuas ntawm qhov sib faib transformer.
Nyob rau hauv lub transformer tis, ntxig rau lub fuse core mus rau theem kab yuav tsum tau soj ntsuam, disconnect lub fuses ntawm lub nruab nrab kab thiab lwm yam ob theem, thiab siv ib tug clamp meter ntawm tus ncej los xyuas cov nyob theem kab los txiav txim qhov chaw ntawm lub. leak.
Txhawm rau txhim kho kev ua haujlwm zoo, txoj haujlwm nce toj tuaj yeem xaiv tau nyob hauv nruab nrab ntawm txoj kab. Los ntawm kev kuaj pom, nws tuaj yeem txiav txim siab seb qhov dej xau yog nyob rau hauv thawj ib nrab lossis ib nrab ntawm kab thib ob, thiab tom qab ntawd cov kab uas pom tias qhov xau tau raug kuaj pom, thiab lwm yam, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau yog qhov tshwm sim, nws tuaj yeem txiav txim siab seb qhov kev xau tuaj yeem yog nyob rau hauv thawj ib nrab lossis ib nrab ntawm cov kab, thiab tom qab ntawd cov kab uas pom tias qhov xau tau raug kuaj pom, thiab lwm yam.
Thaum kawg, cov theem kab pillar insulators nyob rau hauv ib qho kev txiav txim me me tau kuaj pom, thiab cov neeg siv cov kab theem kab txuas nrog rau theem kab hauv qhov ntau tau kuaj pom. Qhov no tuaj yeem ua rau hauv av, lossis tib lub sijhawm thaum cov insulators raug kuaj pom. Txhawm rau txiav txim siab qhov chaw tshwj xeeb ntawm qhov xau.
(2) Tshawb xyuas ntawm tus neeg siv xov tooj qhov chaw.
Thaum cov kab tsis tshua muaj hluav taws xob xa hluav taws xob, clamp meters kuj tuaj yeem siv los txheeb xyuas cov kab kev sib txuas ntawm cov kab hluav taws xob qis qis hauv qhov kev xav tsis thoob.
Thaum kuaj, cov kab hluav taws xob theem thiab cov kab nruab nrab ntawm cov neeg siv hluav taws xob ib leeg yuav tsum muab tso rau hauv lub puab tsaig ntawm lub clamp meter tib lub sijhawm, thiab peb theem xaim thiab nruab nrab ntawm peb-theem fais fab tuag yuav tsum tau muab tso rau hauv lub puab tsaig. tib lub sijhawm.
Yog tias tsis muaj qhov txhaum cai, qhov vector sum ntawm cov khoom thauj tam sim no sib nqus flux yog xoom, thiab qhov taw qhia clamp meter kuj yog xoom; Yog tias muaj cov dej xau tam sim no, lub clamp ammeter tuaj yeem ntes cov xau tam sim no.
4. Tshawb xyuas seb puas muaj cov dej xau hauv cov neeg siv khoom siv hluav taws xob sab hauv thiab cov khoom siv
Txoj kev tshwj xeeb yog siv lub ntsuas hluav taws xob los ntsuas qhov ntws tawm tam sim no ntawm tus neeg siv lub zog nkag, thiab tib lub sijhawm muab tus neeg siv cov khoom siv hluav taws xob thiab teeb nyob rau hauv thiab tawm ib qho los ntawm ib qho, thiab saib cov clamp meter txhawm rau txheeb xyuas cov kev hloov hauv cov xau tam sim no los nrhiav cov khoom siv xau. thiab cov teeb pom kev zoo.
Yog tias tag nrho cov khoom siv thiab cov teeb pom kev zoo, lossis cov khoom siv nrog cov dej xau tau raug tshem tawm, tab sis lub clamp ammeter qhia tau hais tias tus neeg siv tseem muaj cov xau tam sim no, nws muaj peev xwm hais tias tus neeg siv cov kab hluav taws xob tsawg tau xau, thiab yuav tsum tau nqa tawm. raws li qhov xwm txheej tshwj xeeb. deal nrog.
Rau cov dej xau hauv cov kav dej ua ntej faus thiab zais, qhov kev daws teeb meem nkaus xwb yog los hloov lossis rov ua dua lawv.
5. Cov teeb meem uas xav tau kev saib xyuas thaum kuaj xyuas qhov xau thiab hluav taws xob tub sab
Thaum nrhiav kev ua txhaum cai, AC contactor tswj cov kab hluav taws xob tsawg yuav tsum tau xa hluav taws xob rau lub sijhawm luv luv.
Thaum tab tom nrhiav kev ua txhaum cai, ua tib zoo saib xyuas kev nyab xeeb. Ib tug neeg yuav tsum saib xyuas thiab ua raws li kev tiv thaiv kev nyab xeeb. Nco ntsoov tias thaum nyeem cov ntaub ntawv clamp meter, nco ntsoov khaws qhov kev ncua deb ntawm tib neeg lub cev thiab qhov chaw nyob.
