Cov ntsiab lus tseem ceeb hauv kev ntsuas kev ua haujlwm ntawm clamp-on ammeter
1. Cov kev cai ntawm kev nyab xeeb
(1) Peb feem ntau yuav tsum ntsuas tus nqi tam sim no ntawm cov khoom siv hluav taws xob tsawg lossis cov khoom siv hauv kev xyaum. Hauv kev faib cov hluav taws xob qis thiab nws cov khoom siv hluav taws xob hauv kev ntsuas tam sim no, qhov dav dav-voltage busbar kab ntawm interline deb tsis loj txaus, qee qhov clamp-on ammeter lub cev loj dua, qhov ntsuas ntawm qhib lub puab tsaig yuav ua rau luv luv-circuit ntawm theem los yog hauv av, yog tias qhov ntsuas ntawm cov neeg ua haujlwm lub cev tsis ruaj khov los yog caj npab co, nws yuav tshwm sim ntau zaus. Yog li ntawd, raws li qhov tseeb ntawm qhov chaw, ua ntej kev ntsuas, kev siv cov ntaub ntawv insulating tsim nyog los cais cov busbar thiab cov khoom siv hluav taws xob mus rau theem, thiab yuav tsum tau xyuam xim kom tsis txhob kov lwm qhov chaw them nqi.
(2) nyob rau hauv kev ntsuas tam sim no ntawm cov xov hlau liab qab, yog tias qhov kev ncua deb ntawm cov theem sib txawv ntawm cov xov hlau thiab cov xov hlau thiab hauv av me me, yog tias lub puab tsaig ntawm cov rwb thaiv tsev tsis zoo los yog lub tes tsho rwb thaiv tsev tau puas lawm, nws yooj yim los ua rau theem-rau- theem thiab theem-rau-hauv av luv-circuit xwm txheej. Yog li ntawd, nws yog feem ntau tau teev tseg tias lub clamp ammeter tsis raug tso cai los ntsuas qhov tam sim no ntawm tus neeg xyuas pib liab qab, yog tias nws yuav tsum tau ntsuas, nws yuav tsum ua txoj haujlwm zoo ntawm insulating tus neeg xyuas pib liab qab kev sib cais ntawm kev npaj kev nyab xeeb kom tsis txhob muaj xwm txheej tshwm sim. .
(3) Rau ntau lub hom phiaj clamp ammeter, cov haujlwm yuav tsum tsis txhob siv tib lub sijhawm, piv txwv li, hauv kev ntsuas tam sim no, koj tsis tuaj yeem ntsuas qhov hluav taws xob tib lub sijhawm, vim kev nyab xeeb, cov kab xeem yuav tsum yog rub los ntawm lub clamp ammeter.
(4) nyob rau hauv qhov chaw ntsuas, ntau yam khoom siv yuav tsum nyob rau hauv kev txiav txim, qhov ntsuas ntawm txhua qhov ntawm lub cev ntawm cov neeg ua haujlwm thiab lub cev hluav taws xob yuav tsum tau khaws cia ntawm qhov deb txaus, yam tsawg kawg tsis tsawg tshaj li qhov kev nyab xeeb ( low-voltage system kev nyab xeeb nrug ntawm 0.1m-0.3m). Kev nyeem ntawv, feem ntau involuntarily txo lub taub hau los yog tshawb lub duav rov sauv, lub sij hawm no yuav tsum tau them tshwj xeeb mloog mus rau lub caj dab, tshwj xeeb tshaj yog lub taub hau thiab tus nqi ntawm qhov kev nyab xeeb nyob deb ntawm.
