Qhov sib txawv ntawm ob lub zog hloov pauv tsis siv neeg cb thiab pc (2)

ATS (Kev Hloov Pauv Hloov Tsis Siv Neeg) yog ib qho tseem ceeb hauv txhua lub tshuab fais fab uas muaj ntau lub zog fais fab. Yog tias muaj hluav taws xob tsis ua haujlwm lossis lwm yam kev cuam tshuam, nws tso cai rau kev xa hluav taws xob mus rau lwm qhov ntawm cov chaw fais fab no yam tsis muaj teeb meem. Ob hom ATS uas siv ntau yog CB-class thiab PC-class dual power automatic transfer switches. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov zoo, qhov tsis zoo, thiab qhov sib txawv ntawm ob hom no.

Muaj qee qhov sib txawv ntawm CB-level dual power automatic transfer switches thiab PC-level. Ib qho txawv tseem ceeb yog qhov siab ntawm qhov sib cuag. Circuit breakers (MCCB) siv rau hauv CB-level switches feem ntau tsis tuaj yeem tiv taus lub sijhawm luv luv uas tiv taus tam sim no, ua rau lub zog sib cuag qis dua thiab yooj yim dua rau kev thawb lossis thawb tawm. PC-grade switches, ntawm qhov tod tes, tuaj yeem tiv taus lub zog overload ntawm 20Ie thiab siab dua thiab xav tau lub zog sib cuag ntau dua, ua rau lawv tsis tshua muaj feem yuav raug thawb tawm.

Lwm qhov txawv yog kev xaiv cov khoom siv sib cuag. CB chav kawm dual fais fab hloov pauv tsis siv neeg hloov pauv Circuit Court breakers feem ntau siv cov nyiaj tungsten thiab nyiaj tungsten carbide cov ntaub ntawv. Cov ntaub ntawv no tau raug xaiv rau lawv lub peev xwm los tua cov arcs zoo. Txawm li cas los xij, lawv yooj yim rau oxidation, uas tuaj yeem cuam tshuam rau lawv cov kev ua tau zoo. Hauv kev sib piv, PC-qib switches xav txog qhov tshwm sim ntawm oxidation thiab xaiv cov ntaub ntawv sib cuag raws li.

Lub tswv yim tsim tom qab ob hom kev hloov pauv kuj txawv. Lub CB-class dual power automatic transfer switch yog tsim los ntawm lub circuit breaker thiab yog lub luag haujlwm rau kev tawg lub arc. Qhov kev tsim no xav tau lub tshuab kom muaj peev xwm mus ncig sai, uas tuaj yeem ua rau muaj teeb meem xws li swb buckles. PC-grade switches, ntawm qhov tod tes, tsis ntsib teeb meem zoo li no vim lawv tsis vam khom lub circuit breakers rau lub hom phiaj tawg arc.

Qhov deb ntawm qhov hluav taws xob thiab qhov chaw nkag (qhov deb uas xav tau rau kev ua haujlwm hluav taws xob kom muaj kev nyab xeeb) kuj txawv ntawm ob hom switches. Qhov dav dav ntawm hluav taws xob thiab qhov chaw nkag ntawm PC-level dual power automatic transfer switches yog 180% thiab 150% ntawm cov qauv ntawm circuit breaker. Qhov no yog los tiv thaiv cov teeb meem kev sib tshooj ntawm lub zog ntawm ob lub zog thaum lub sijhawm hloov pauv.

Hauv kev xaus, CB-level thiab PC-level dual power automatic transfer switches muaj qhov zoo thiab qhov tsis zoo. Class CB switches tej zaum yuav muaj qhov siab me dua, qhov yuav tsum tau ua rau cov ntaub ntawv sib cuag tshwj xeeb, tej zaum yuav muaj teeb meem oxidation, thiab kev tsim qauv nyuaj nrog cov circuit breakers. PC-grade switches, ntawm qhov tod tes, muab qhov siab dua, kev ua haujlwm overcurrent zoo dua, kev xav txog kev oxidation ntawm cov ntaub ntawv sib cuag, thiab kev tsim uas tshem tawm qhov xav tau rau circuit breaker rau kev cuam tshuam arc. Kev xaiv ntawm ob hom no nyob ntawm qhov yuav tsum tau ua ntawm lub zog fais fab thiab tej zaum yuav muaj kev pheej hmoo nrog txhua hom.
