Ib qho kev qhia luv luv rau cov neeg pib tshiab txog vim li cas modular UPSs txias dua thiab nws tshwm sim li cas.
Raws li lawv cov qauv tsim, cov khoom siv hluav taws xob tsis cuam tshuam rau cov chaw khaws ntaub ntawv tau muab faib ua ob pawg loj: monoblock thiab modular. Lub qub yog nyob rau hauv ib txwm hom ntawm UPS, lub tom kawg yog tus tshiab thiab ntau tshaj.
Dab tsi yog qhov txawv ntawm monoblock thiab modular UPSs?
Hauv monoblock uninterruptible fais fab mov, lub zog tso zis yog muab los ntawm ib lub hwj chim unit. Nyob rau hauv modular UPSs, cov khoom tseem ceeb yog tsim nyob rau hauv daim ntawv ntawm cais modules, uas yog muab tso rau hauv unified txee thiab ua hauj lwm ua ke. Txhua qhov ntawm cov qauv no tau nruab nrog kev tswj hwm processor, charger, inverter, rectifier thiab sawv cev rau lub zog tag nrho ntawm UPS.
Cia peb piav qhov no nrog ib qho piv txwv yooj yim. Yog tias peb siv ob lub zog siv hluav taws xob tsis cuam tshuam - monoblock thiab modular - nrog lub zog ntawm 40 kVA, thawj zaug yuav muaj ib lub zog hluav taws xob nrog lub zog ntawm 40 kVA, thiab qhov thib ob yuav muaj, piv txwv li, ntawm plaub lub zog hluav taws xob nrog lub zog. 10 kVA ib.
Scaling xaiv
Thaum siv monoblock UPSs nrog rau qhov kev xav tau ntawm lub zog, nws yog ib qho tsim nyog los txuas rau lwm chav tsev tag nrho ntawm tib lub zog sib npaug rau qhov uas twb muaj lawm. Qhov no yog ib txoj kev nyuaj heev.
Modular cov kev daws teeb meem muab kev tsim qauv yooj yim dua. Hauv qhov no, ib lossis ntau lub modules tuaj yeem txuas nrog rau chav ua haujlwm uas twb muaj lawm. Qhov no yog ib txoj hauv kev yooj yim uas tuaj yeem ua tiav hauv lub sijhawm luv luv.
Muaj peev xwm du zog nce
Ib qho kev nce siab hauv lub zog yog qhov tseem ceeb ntawm thawj theem ntawm kev ua haujlwm ntawm cov ntaub ntawv chaw. Nws yog ib qho laj thawj heev uas thawj lub hlis nws yuav yog 30-40% loaded. Nws yog qhov ua tau zoo dua thiab kev lag luam siv cov khoom siv hluav taws xob tsis cuam tshuam uas tsim tshwj xeeb rau lub zog no. Raws li cov neeg siv khoom nthuav dav, cov ntaub ntawv chaw thauj khoom yuav nce ntxiv, thiab nrog rau nws qhov kev xav tau rau cov khoom siv hluav taws xob ntxiv yuav nce ntxiv.
Nws yog qhov yooj yim los ua kom lub zog ntawm UPS kauj ruam yog kauj ruam nrog rau kev tsim kho vaj tse. Thaum siv cov khoom siv hluav taws xob monoblock tsis cuam tshuam, kev nce siab hauv lub zog yog tsis yooj yim sua hauv txoj cai. Nrog modular UPSs qhov no yooj yim rau kev siv.
UPS kev cia siab
Thaum tham txog kev ntseeg siab, peb yuav siv ob lub ntsiab lus: lub sijhawm nruab nrab ntawm kev ua tsis tiav (MTBF) thiab lub sijhawm hloov kho (MTTR).
MTBF yog qhov muaj txiaj ntsig zoo. Tus nqi ntawm lub sij hawm nruab nrab ntawm kev ua tsis tiav yog raws li hauv qab no postulate: kev ntseeg siab ntawm lub kaw lus txo qis nrog qhov nce ntawm nws cov khoom.
Hauv qhov ntsuas no, monoblock UPSs muaj qhov zoo dua. Yog vim li cas yog qhov yooj yim: modular uninterruptible fais fab mov muaj ntau yam khoom thiab connectors, txhua yam uas yog xam tau tias yog ib tug tej zaum point ntawm tsis ua hauj lwm. Raws li txoj cai, qhov muaj peev xwm ua tsis tiav yog siab dua ntawm no.
Txawm li cas los xij, rau cov khoom siv hluav taws xob tsis cuam tshuam siv hauv cov chaw khaws ntaub ntawv, nws tsis yog qhov tsis ua haujlwm nws tus kheej yog qhov tseem ceeb, tab sis ntev npaum li cas UPS yuav tsis ua haujlwm. Qhov kev ntsuas no yog txiav txim los ntawm lub sijhawm nruab nrab ntawm lub sijhawm rov qab los (MTTR).
Ntawm no qhov zoo dua yog twb nyob rau sab ntawm modular blocks. Lawv muaj qhov qis MTTR vim tias txhua qhov module tuaj yeem hloov tau sai yam tsis muaj kev cuam tshuam lub zog. Txhawm rau ua qhov no, nws yog qhov tsim nyog uas cov qauv no yuav tsum muaj nyob hauv Tshuag, thiab nws qhov kev tshem tawm thiab kev teeb tsa tuaj yeem ua tau los ntawm ib tus kws tshaj lij. Qhov tseeb, nws yuav siv sijhawm tsis tshaj 30 feeb.
Nrog monoblock uninterruptible fais fab mov, qhov teeb meem yog ntau nyuaj. Nws yuav tsis tuaj yeem kho lawv sai li sai tau. Qhov no yuav siv li ob peb teev mus rau ob peb hnub.
Txhawm rau txiav txim siab qhov ua txhaum cai ntawm lub kaw lus, koj tuaj yeem siv ib qho ntxiv - muaj lossis lwm yam kev ua haujlwm. Qhov ntsuas no siab dua, qhov siab dua lub sij hawm nruab nrab ntawm kev ua tsis tiav (MTBF) thiab qis dua qhov nruab nrab lub sijhawm rov qab los (MTTR). Cov qauv sib thooj yog raws li hauv qab no:
nruab nrab muaj (operability) =
Nyob rau hauv kev sib raug zoo rau modular UPSs, qhov teeb meem yog raws li nram no: lawv MTBF tus nqi yog qis dua li ntawm monoblock UPSs, tab sis nyob rau tib lub sij hawm lawv muaj ib tug tseem ceeb MTTR tus nqi. Yog li ntawd, qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob tsis cuam tshuam tsis cuam tshuam yog siab dua.
Hwj chim Siab
Lub monoblock system yuav tsum muaj zog ntau dua vim tias nws tsis muaj zog. Cia peb piav qhia qhov no siv ib qho piv txwv rau N + 1 redundancy scheme. N yog tus nqi thauj khoom uas yuav tsum tau ua haujlwm rau cov khoom siv hauv cov ntaub ntawv. Hauv peb cov ntaub ntawv, peb yuav muab nws sib npaug rau 90 kVA. Lub tswv yim N + 1 txhais tau hais tias 1 cov khoom cia tseem tsis tau siv hauv lub cev ua ntej ua tsis tiav.
Thaum siv lub tshuab hluav taws xob monoblock tsis cuam tshuam nrog lub zog ntawm 90 kVA, txhawm rau siv N + 1 Circuit Court, koj yuav tsum siv lwm chav tsev zoo ib yam. Raws li qhov tshwm sim, tag nrho cov txheej txheem rov ua dua yuav yog 90 kVA.
Thaum siv modular UPSs nrog lub peev xwm ntawm 30 kVA, qhov xwm txheej txawv. Nrog tib lub thauj khoom, siv N + 1 circuit, koj yuav xav tau lwm qhov module ntawm tib hom. Raws li qhov tshwm sim, tag nrho cov txheej txheem rov ua dua yuav tsis yog 90 kVA, tab sis tsuas yog 30 kVA.
Li no qhov xaus: kev siv cov khoom siv hluav taws xob modular tuaj yeem txo qhov kev siv hluav taws xob ntawm cov ntaub ntawv hauv qhov chaw tag nrho.
Cov Economy
Yog tias koj siv ob lub zog tsis cuam tshuam ntawm tib lub zog, ces tus monoblock ib qho pheej yig dua li qhov modular. Vim li no, monoblock UPSs tseem nrov. Txawm li cas los xij, nce lub zog tso zis yuav ua ob npaug rau tus nqi ntawm lub kaw lus, vim tias lwm chav tsev zoo ib yam yuav tsum tau ntxiv rau qhov uas twb muaj lawm. Tsis tas li ntawd, yuav tsum tau teeb tsa thaj ua rau thaj thiab faib cov boards, nrog rau cov kab tshiab.
Thaum siv cov khoom siv hluav taws xob tsis cuam tshuam tsis cuam tshuam, lub zog hluav taws xob tuaj yeem nce siab. Qhov no txhais tau hais tias koj yuav tau siv nyiaj rau kev yuav khoom xws li ib tug xov tooj ntawm modules uas txaus los txaus siab rau cov uas twb muaj lawm fais fab mov xav tau kev pab. Tsis muaj cov khoom tsis tsim nyog.
xaus
Monoblock uninterruptible fais fab mov yog tus nqi qis thiab yooj yim rau configure thiab khiav lag luam. Nyob rau tib lub sij hawm, lawv nce lub zog noj ntawm cov ntaub ntawv chaw thiab nyuaj rau scale. Cov tshuab zoo li no yooj yim thiab siv tau zoo qhov twg yuav tsum muaj peev xwm me me thiab tsis xav kom lawv nthuav dav.
Modular UPSs yog tus cwj pwm los ntawm qhov yooj yim scalability, tsawg kawg lub sij hawm rov qab, muaj kev ntseeg siab thiab muaj. Cov tshuab no yog qhov zoo tshaj plaws rau kev nce cov ntaub ntawv chaw muaj peev xwm mus rau txhua qhov ntawm tus nqi tsawg.
