Switchgear vs Switchboard
Dab tsi yog qhov txawv ntawm switchboard thiab switchgear?
Ntxiv nrog rau kev ua haujlwm sib txawv, ib puag ncig kev teeb tsa, cov qauv sab hauv thiab cov khoom tswj, lub thawv xa khoom thiab lub tshuab hloov pauv yog yam ntxwv ntawm qhov sib txawv. Lub thawv faib yog me me thiab tuaj yeem muab zais rau hauv phab ntsa lossis sawv hauv av. Lub switchgear yog loj thiab tsuas yog ntsia tau rau hauv substations thiab faib chav.
Lub switchgear yog ib qho 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. Txhua ceg tau teeb tsa raws li kev xav tau, xws li ntsuas ntsuas, tsis siv neeg tswj, lub cev muaj zog sib nqus hloov, ntau yam AC contactors, thiab lwm yam. Qee qhov ntawm lawv kuj muaj chav faib hluav taws xob, chav faib hluav taws xob tsawg, thiab cov busbars.
Lub luag haujlwm tseem ceeb ntawm switchgear yog qhib thiab tawm, 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. Lub Cheebtsam nyob rau hauv lub switchgear feem ntau muaj xws li Circuit Court breakers, disconnectors, load keyboards, kev khiav hauj lwm mechanisms, transformers thiab ntau yam kev tiv thaiv pab kiag li lawm. Muaj ntau txoj hauv kev los faib cov khoom siv hluav taws xob, xws li detachable switchgear thiab tsau switchgear ntsia raws li lub Circuit Court breaker; los yog raws li tus qauv ntawm lub txee, nws muaj peev xwm muab faib ua qhib switchgear, hlau-pob switchgear thiab hlau-pob armored Install switchgear. Raws li qib voltage sib txawv, nws tuaj yeem muab faib ua switchgear, nruab nrab voltage switchgear thiab low voltage switchgear. Feem ntau yog siv nyob rau hauv ntau zaus xws li fais fab nroj tsuag, substations, petrochemicals, metallurgical steel dov, lub teeb kev lag luam textiles, factories thiab mines, nyob rau hauv lub quarters, high-sawv vaj tse, thiab lwm yam.
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 rau lub tshuab hluav taws xob. Lub hwj chim faib txee yog lub ntsiab lus dav dav rau lub chaw tswj lub cev muaj zog. Lub hwj chim faib txee yog siv nyob rau hauv lub sij hawm uas lub load yog tawg thiab muaj ob peb kab; lub chaw tswj lub cev muaj zog yog siv nyob rau hauv lub sij hawm uas lub load yog concentrated thiab muaj ntau yam circuits. Lawv faib hluav taws xob hluav taws xob los ntawm cov khoom siv hluav taws xob sab saud mus rau cov khoom nyob ze. Cov cuab yeej zoo li no yuav tsum tau muab kev tiv thaiv thiab kev tswj xyuas lub nra. Lawv xa mus rau cov khoom siv hluav taws xob faib hluav taws xob xws li hluav taws xob faib hluav taws xob, hluav taws xob faib hluav taws xob thiab lub ntsuas hluav taws xob.
