Cov yam tseem ceeb rau kev xaiv lub tshuab hloov pauv tsis siv neeg yog dab tsi?

1. Kev tshuaj xyuas qhov sib piv ntawm cov yam ntxwv thiab lub peev xwm thauj khoom

1.1 Kev txheeb xyuas hom khoom thauj

Muaj kev tshuaj xyuas kom meej txog hom load (resistive, inductive, capacitive, lossis mixed). Cov hom load sib txawv muaj feem cuam tshuam loj heev rau qhov tam sim no surge, pib yam ntxwv ntawm ATS. Piv txwv li, inductive loads xws li lub cev muaj zog pib yuav tsim cov tam sim no pib siab, xav kom ATS muaj peev xwm overload thiab shock tolerance zoo dua; capacitive loads yuav tsim overvoltage thaum lub sijhawm switching, ua rau ATS muaj cov txheej txheem tiv thaiv sib xws.

1.2 Kev faib tawm qhov tseem ceeb ntawm kev thauj khoom

Qhov tseem ceeb ntawm lub nra hnyav raug muab faib ua thawj (xws li cov khoom siv ICU hauv tsev kho mob, cov neeg rau zaub mov tseem ceeb hauv cov chaw khaws ntaub ntawv), theem ob (xws li cov khoom siv hauv chaw ua haujlwm ib txwm, teeb pom kev zoo hauv cov tsev lag luam), thiab theem peb (xws li cua txias thiab cov khoom siv tsis tseem ceeb). Cov theem sib txawv ntawm qhov tseem ceeb muaj cov kev cai sib txawv rau ATS hais txog lub sijhawm hloov pauv thiab kev ntseeg tau. Cov nra hnyav tseem ceeb yuav tsum tau muab tso ua ntej rau kev muab hluav taws xob tas mus li.

2. Lub sijhawm hloov pauv thiab cov kev cai hloov pauv

2.1 Kev tshuaj xyuas lub sijhawm fais fab uas tso cai

Lub sijhawm tua hluav taws xob siab tshaj plaws rau qhov khoom raug txiav txim siab raws li nws cov yam ntxwv. Piv txwv li, cov khoom siv computer feem ntau tso cai rau lub sijhawm tua hluav taws xob luv dua, feem ntau yog nyob rau hauv millisecond; thaum qee cov khoom siv teeb pom kev zoo ib txwm tso cai rau lub sijhawm tua hluav taws xob ntev dua.

2.2 Cov hom thiab cov yam ntxwv ntawm kev hloov pauv

Cov txheej txheem hloov pauv ntawm ATS tau qhia, xws li PC theem (hom hloov pauv tag nrho) thiab CB theem (circuit breaker hom hloov pauv). PC theem ATS muaj cov yam ntxwv ntawm cov qauv yooj yim, hloov pauv ceev, thiab kev ntseeg siab, thiab tsim nyog rau cov xwm txheej uas muaj kev xav tau siab rau lub sijhawm hloov pauv; CB theem ATS muaj kev tiv thaiv overload thiab luv luv, tab sis nws lub sijhawm hloov pauv ntev dua, tsim nyog rau cov xwm txheej uas muaj kev xav tau kev tiv thaiv siab dua.

2.3 Kev xaiv lub sijhawm hloov pauv

Cov yam ntxwv tseem ceeb ntawm ATS, xws li lub sijhawm hloov pauv tag nrho (suav nrog lub sijhawm qhib thiab kaw) thiab lub sijhawm hloov pauv, tau txhais meej thiab xyuas kom meej tias ua tau raws li qhov yuav tsum tau ua ntawm lub nra. Tib lub sijhawm, kev sib dhos ntawm cov chaw muab hluav taws xob sib txawv raug txiav txim siab. Rau cov chaw muab hluav taws xob asynchronous, ATS nrog kev ua haujlwm hloov pauv asynchronous yuav tsum tau xaiv.

3. Cov cim qhia txog kev ntseeg siab thiab cov kev cai txij nkawm

3.1 Lub Sijhawm Nruab Nrab Ntawm Qhov Ua Tsis Tau Zoo (MTBF)

MTBF yog ib qho cim qhia tseem ceeb rau kev ntsuas qhov kev ntseeg tau ntawm ATS. Kev xaiv cov khoom ATS uas muaj tus nqi MTBF siab dua tuaj yeem txo qhov feem pua ​​​​​​ntawm kev ua tsis tiav. Nkag siab txog cov ntaub ntawv MTBF uas cov chaw tsim khoom muab thiab ua qhov kev ntsuam xyuas raws li cov ntawv thov tiag tiag.

3.2 Lub neej siv tshuab thiab lub neej hluav taws xob

Ua tib zoo saib xyuas lub neej siv tshuab (lub sijhawm ua haujlwm) thiab lub neej hluav taws xob (lub sijhawm ua haujlwm thauj khoom) ntawm ATS. Lub neej siv tshuab thiab lub neej hluav taws xob ntev npaum li cas, lub neej siv tshuab ntawm ATS ntev npaum li ntawd, thiab qhov zaus txij nkawm thiab hloov pauv tsawg dua. Xaiv ATS uas muaj lub neej txaus raws li qhov zaus siv thiab xyoo uas xav tau.
