Contraindications thiab Countermeasures rau Siv Clamp Ammeter
1. Tsis txhob kuaj lossis xyuas ua ntej siv
Txhawm rau kom ntseeg tau qhov tseeb ntawm kev ntsuas, xyuas kom muaj kev nyab xeeb ntawm tus kheej ntawm tus neeg teb xov tooj ntsuas, thiab xyuas kom muaj kev ua haujlwm zoo ntawm cov hluav taws xob hauv kev sim, nws yuav tsum tau kuaj xyuas ua ntej siv lub clamp ammeter. Cov ntsiab lus tseem ceeb ntawm kev tshuaj xyuas yog: seb lub rooj plaub thiab lub taub hau iav puas puas thiab tawg; seb cov khoom siv insulating ntawm lub puab tsaig hlau tseem ceeb thiab tus kov tsis zoo; seb tus pointer ntawm lub meter lub taub hau yog hloov tau thiab seb nws nyob ntawm xoom txoj hauj lwm. Yog tias tsis yog, koj tuaj yeem tig lub tshuab xoom txoj hauj lwm mechanism los kho rau xoom txoj hauj lwm. Lub moos yog siv los ua lub moos zoo. Ntxiv rau qhov kev soj ntsuam pom saum toj no, yuav tsum tau ua qhov kev ntsuam xyuas los ntawm kev siv lub ntsuas hluav taws xob kom paub meej tias muaj cov dej ntws tam sim no, ntawm tib hom uas yuav tsum tau siv lub 'meter', thiab nyob rau. conductors paub txog tus naj npawb ntawm cov tam sim no. Kuaj thiab paub meej tias nws yog qhov qub raws li qhov ntsuas ntsuas ua ntej nws tuaj yeem muab tso rau hauv kev siv.
2. Tsis quav ntsej txog hom ntsuas tam sim no thiab xaiv qhov phenotype ntawm qhov xav tau
Hom clamp ammeter siv rau kev ntsuas yuav tsum sib haum nrog hom tam sim no los ntsuas. Yog hais tias qhov zaus thiab waveform ntawm qhov ntsuas tam sim no yog tus qauv siv hluav taws xob zaus tam sim no, lub dav hlau clamp ammeter tuaj yeem ua haujlwm. Yog tias muaj qhov yuav tsum tau ua rau kev ntsuas qhov tseeb, nws yog qhov tsim nyog los xaiv lub transformer clamp ammeter, vim hais tias nws qhov tseeb theem yog me ntsis siab dua li ntawm electromagnetic clamp ammeter; Yog hais tias qhov ntsuas DC tam sim no, lub zog zaus tam sim no nrog qhov loj waveform distortion, tsis tshua muaj zaus lossis loj hloov pauv rotor tam sim no), nws yog ib qho tsim nyog los xaiv lub electromagnetic clamp ammeter. Txwv tsis pub, qhov tam sim no yuav tsis raug ntsuas, lossis yuav ntsuas tau, tab sis qhov ntsuas qhov ntsuas tsis tuaj yeem ntseeg tau.
3. Siv cov clamp ammeter zoo tib yam los ntsuas qhov hluav taws xob siab tam sim no
Ordinary clamp ammeters tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb rau kev ntsuas cov hluav taws xob hluav taws xob vim lawv cov qauv thiab cov ntaub ntawv insulating. Tsis tas li ntawd, feem ntau ntawm cov xaim hluav taws xob siab yog cov xov hlau liab qab. Nws yog ib qho nyuaj heev thiab txaus ntshai rau insulate qhov ntsuas nyob rau hauv lub xeev them. Thaum cov hlau tsoo cov hlau tseem ceeb ntawm lub puab tsaig, los yog qhov hluav taws xob siab ncaj qha tawm ntawm qhov ntsuas thiab tus neeg, qhov tshwm sim yuav muaj kev puas tsuaj. Yog li ntawd, qhov zoo tib yam clamp ammeters tsuas yog siv tau rau kev ntsuas tam sim no ntawm 380V thiab hauv qab circuits, thiab raug txwv nruj rau kev ntsuas tam sim no ntawm high-voltage circuits.
4. Kev xaiv tsis zoo thiab tuav cov ntsiab lus ntsuas
Kev xaiv thiab tuav cov ntsiab lus ntsuas yuav tsum tau kho nrog ceev faj, uas cuam tshuam nrog kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv hluav taws xob. Nws yuav tsum tau xaiv ntawm cov hlau nrog insulating sheath kom ntau li ntau tau, thiab nws yog qhov zoo tshaj plaws los xaiv ntawm cov kab nrog cov rwb thaiv tsev zoo; Thaum ntsuas qhov tam sim no ntawm cov hluav taws xob tsawg-voltage fuse lossis low-voltage busbar teem horizontally, nws yog ib qho tsim nyog yuav tsum tau siv lub insulating board nrog zoo rwb thaiv tsev kev ua tau zoo los txuas lub fuse los yog busbar. Kev rho tawm theem yog nqa tawm kom tsis txhob muaj luv luv Circuit Court thiab hluav taws xob poob siab.
5. Kev paub txog kev ruaj ntseg tsis muaj zog thiab kev tiv thaiv tsis txaus
Qee cov kws tshawb fawb muaj kev paub txog kev nyab xeeb tsis muaj zog, ntseeg tau qee qhov kev paub dhau los, tsis muaj kev tiv thaiv zoo, thiab muaj lub siab tsis zoo. Tus cwj pwm no yog qhov txaus ntshai heev. Thaum lub sijhawm ntsuas kev ua haujlwm, cov khau insulated thiab hnab looj tes yuav tsum hnav. Cov khau insulated, cov hnab looj tes insulated thiab cov khaub ncaws ua haujlwm yuav tsum nyob hauv lub xeev qhuav, thiab lub cev lub cev yuav tsum ruaj khov. Tib neeg lub cev yuav tsum nyob deb txaus los ntawm lwm lub cev raug them.
