Dab tsi yog qhov sib txawv ntawm switchgear thiab hluav taws xob faib txee?
Jul 21, 2020
Ntxiv rau cov kev ua haujlwm sib txawv, cov chaw ib puag ncig, cov qauv sab hauv, cov khoom tswj tau, thiab lwm yam, cov thawv hluav taws xob faib hluav taws xob thiab cov hloov hluav taws xob tau pom qhov txawv los ntawm qhov sib txawv thiab qhov loj me, uas tuaj yeem muab zais hauv phab ntsa lossis sawv rau hauv av. Txawm li cas los xij, chav hloov hluav taws xob yog qhov loj hauv qhov loj thiab tsuas yog ntsia tau rau hauv chav faib khoom faib thiab fais fab.
Switchgear yog ib hom khoom siv hluav taws xob. Qhov kab sab nraud ntawm lub pob hluav taws xob nkag mus rau lub ntsiab tswj hluav taws xob hauv lub txee ua ntej, thiab tom qab ntawd nkag mus rau qhov sub-control hloov, thiab txhua ceg tau teeb tsa raws li nws xav tau. Xws li kev ntsuas khoom, kev tswj tsis siv neeg, lub tshuab hluav taws xob hloov pauv, ntau yam AC contactors, thiab lwm yam. Ib txhia yog nruab nrog chav ntsuas hluav taws xob ntau thiab chav hloov hluav taws xob tsawg, nrog cov kab hluav taws xob siab, xws li cov chaw tsim hluav taws xob, thiab qee qhov kuj tau nruab nrog kev tiv thaiv tsawg-tsawg rau cov cuab yeej tseem ceeb Thauj khoom.
Lub luag haujlwm tseem ceeb ntawm switchgear yog qhib thiab kaw, tswj thiab tiv thaiv cov khoom siv hluav taws xob thaum lub sijhawm txheej txheem ntawm lub zog hluav taws xob, kev xa mus, kev faib hluav taws xob thiab kev hloov hluav taws xob hauv lub zog. Cov Cheebtsam hauv lub txee hloov hluav taws xob yog tsuas yog tsim ntawm cov hluav taws xob sib txuas, cais cov hloov mus, load hloov mus, kev ua haujlwm ua haujlwm, sib nrig sib xyaw thiab ntau yam kev tiv thaiv. Muaj ntau ntau txoj kev faib rau cov khoom siv hloov chaw. Piv txwv li, txoj kev teeb tsa ntawm cov hluav taws xob hauv Circuit Court tuaj yeem muab faib mus rau hauv cov txee hluav taws xob tshem tau thiab lub thawv hloov hluav taws xob hloov chaw; los yog raws li cov qauv txee sib txawv, lawv muaj peev xwm muab faib ua cov khoom siv hluav taws xob qhib lub thawv, cov hlau thaiv hluav taws xob cov txee hluav taws xob, thiab cov hlau thaiv lub thawv muaj qhov hloov pauv; raws li qib voltage sib txawv, nws muaj peev xwm raug faib ua hluav taws xob ntau hluav taws xob, hloov hluav taws xob nruab nrab thiab hloov hluav taws xob tsawg. Nws yog qhov tsim nyog rau ntau lub sijhawm xws li cov chaw tsim hluav taws xob, cov chaw hloov pauv, petrochemicals, cov xim hlau ua kom yob, lub teeb pom kev lag luam thiab cov ntaub, cov chaw ua haujlwm thiab cov tuam txhab tsuas, thaj chaw nyob, thiab cov tsev siab.
Lub thawv faib hluav taws xob (lub thawv) tau muab faib ua lub thawv faib hluav taws xob (lub thawv), lub teeb xa hluav taws xob faib tawm (lub thawv), thiab metering txee (thawv). Nws yog cov khoom siv zaum kawg ntawm lub zog hluav taws xob. Lub tshuab hluav taws xob faib tawm yog cov lus dav dav rau lub chaw tswj lub cev muaj zog. Lub thawv faib fais fab siv nyob rau qee kis uas lub nra sib kis thiab cov kab sib kis tsawg dua; lub chaw tswj lub cev muaj zog yog siv nyob rau hauv zaus thaum lub luag haujlwm thauj khoom thiab muaj ntau lub voj voog. Lawv faib hluav taws xob lub zog ntawm qee qhov kev sib kis ntawm cov qib siab ntawm lub zog faib cov khoom hluav taws xob rau cov thau nyob ze. Qeb qib ntawm cov khoom no yuav tsum muaj kev tiv thaiv, soj ntsuam thiab tswj ntawm lub nra.
