Ntxiv nrog rau qhov sib txawv ntawm kev ua haujlwm, ib puag ncig kev teeb tsa, cov qauv sab hauv, thiab cov khoom tswj hwm, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob muaj qhov sib txawv ntawm qhov sib txawv.Lub hwj chim faib txee yog me me thiab tuaj yeem muab zais rau hauv phab ntsa lossis sawv hauv av.Lub switchgear yog loj, thiab nws tsuas yog ntsia nyob rau hauv lub substation thiab lub hwj chim faib chav tsev. Switchgear yog ib yam khoom siv hluav taws xob.Cov kab sab nraud ntawm lub txee hloov ua ntej nkag mus rau qhov hloov pauv tseem ceeb hauv lub txee, thiab tom qab ntawd nkag mus rau qhov hloov pauv hloov, thiab txhua ceg tau teeb tsa raws li nws xav tau, xws li cov twj paj nruag, tsis siv neeg tswj, lub cev muaj zog sib nqus, ntau yam AC contactors , thiab lwm yam. Ib txhia kuj tau nruab nrog high-voltage chav thiab low-voltage chav switchgear, nrog high-voltage busbars, xws li fais fab nroj tsuag, thiab lwm yam. Thiab ib co kuj nruab nrog tsawg-cycle load shedding los tiv thaiv cov khoom tseem ceeb. Lub luag haujlwm tseem ceeb ntawm lub switchgear yog qhib thiab kaw, tswj thiab tiv thaiv cov khoom siv hluav taws xob hauv cov txheej txheem ntawm kev tsim hluav taws xob, kev xa tawm, kev faib tawm thiab kev hloov hluav taws xob hauv lub zog hluav taws xob.Cov khoom nyob rau hauv lub txee hloov yog tsuas yog tsim los ntawm Circuit Court breakers, disconnect keyboards (insolator hloov), load keyboards, kev khiav hauj lwm mechanisms, transformers thiab ntau yam kev tiv thaiv pab kiag li lawm.Muaj ntau txoj kev faib tawm ntawm switchgear, xws li kev teeb tsa ntawm Circuit Court breakers tuaj yeem muab faib ua cov hloov pauv hloov tau thiab cov hloov pauv ruaj khov.Los yog raws li tus qauv ntawm lub txee, nws tuaj yeem muab faib ua qhov qhib switchgear, hlau-cuam tshuam switchgear, thiab hlau-pob armored switchgear.Raws li qhov sib txawv voltage theem, nws tuaj yeem muab faib ua high-voltage switchgear, nruab nrab-voltage switchgear thiab low-voltage switchgear.Feem ntau yog siv rau hauv cov chaw tsim hluav taws xob, cov chaw tso hluav taws xob, cov khoom siv petrochemical, metallurgical steel dov, lub teeb kev lag luam thiab textiles, factories thiab mines, cov tsev nyob, cov tsev siab thiab lwm yam sib txawv. Cov khoom siv hluav taws xob faib hluav taws xob (lub thawv) tau muab faib ua cov khoom siv hluav taws xob faib hluav taws xob (cov thawv), cov khoom siv hluav taws xob faib hluav taws xob (lub thawv), thiab cov khoom ntsuas ntsuas (lub thawv), uas yog cov khoom siv kawg ntawm lub zog faib hluav taws xob.Fais fab faib txee yog ib lo lus dav dav rau lub cev muaj zog tswj chaw.Cov khoom siv hluav taws xob faib hluav taws xob yog siv nyob rau hauv cov xwm txheej uas cov khoom tawg tau tawg thiab muaj ob peb lub voj voog.Nyob rau hauv lub chaw tswj lub cev muaj zog, lub hwj chim faib txee yog siv rau lub sij hawm uas lub load yog concentrated thiab muaj ntau yam circuits.Lawv faib cov hluav taws xob hluav taws xob ntawm qee qhov hluav taws xob ntawm cov khoom siv hluav taws xob sab saud mus rau qhov ze tshaj plaws.Cov khoom siv qib no yuav tsum muaj kev tiv thaiv, kev saib xyuas thiab tswj cov khoom thauj.
