Hauv tsab xov xwm dhau los txog Peb tau hais tias qee qhov racks muaj ATS tau teeb tsa - tsis siv neeg hloov chaw cia. Tab sis qhov tseeb, nyob rau hauv ib qho chaw cov ntaub ntawv, ATSs tau muab tso rau tsis yog nyob rau hauv lub khib, tab sis raws li tag nrho cov hluav taws xob txoj kev. Hauv ntau qhov chaw lawv daws teeb meem sib txawv:
- nyob rau hauv lub ntsiab faib boards (MSB), lub AVR hloov lub load ntawm cov tswv yim los ntawm lub nroog thiab backup hwj chim los ntawm diesel generator teev (DGS);
- nyob rau hauv cov khoom siv hluav taws xob tsis cuam tshuam (UPS), ATS hloov lub thauj khoom los ntawm lub ntsiab lus nkag mus rau lub bypass (ntxiv rau qhov no hauv qab no);
- nyob rau hauv racks, ATS hloov lub load los ntawm ib qho kev nkag mus rau lwm qhov thaum muaj teeb meem nrog ib qho ntawm cov khoom siv.
ATS nyob rau hauv cov txheej txheem fais fab mov rau DataLine cov chaw zov me nyuam.
Peb yuav tham txog qhov twg AVRs tau siv thiab qhov twg niaj hnub no.
Muaj ob hom ATS tseem ceeb: ATS (tsis siv neeg hloov pauv hloov pauv) thiab STS (zoo hloov pauv hloov pauv hloov pauv). Lawv sib txawv hauv cov qauv kev khiav hauj lwm thiab lub hauv paus thiab siv rau kev ua haujlwm sib txawv. Nyob rau hauv luv luv, STS yog ib tug smarter ATS. Nws hloov cov loads sai dua thiab feem ntau siv rau ntau dua loads / tam sim no. Nws yog qhov hloov tau yooj yim dua hauv kev teeb tsa, tab sis nws yuav raug rau qhov vagaries ntawm lub network: nws yuav tsis kam ua haujlwm yog tias 2 cov khoom siv tau siv los ntawm ntau qhov chaw, piv txwv li: los ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob diesel.
AVR nyob rau hauv lub ntsiab switchboard
Lub ntsiab ATS ntawm ib lub chaw ntaub ntawv nees nkaum xyoo dhau los zoo li ib tug complex system ntawm contactors thiab relays.
AVR qauv los ntawm thaum ntxov 2000s.
Tam sim no AVR yog ib qho khoom siv sib txuas ua ke.
ATS system nyob rau hauv lub ntsiab switchboard tswj lub input circuit breakers thiab muab lus txib kom pib thiab nres lub diesel generator teeb. Thaum lub load yog ntau tshaj 2 MW ntawm lub ntsiab switchboard theem, nws tsis pom zoo kom chase ceev. Txawm hais tias nws hloov pauv sai, nws yuav siv sijhawm kom txog thaum lub tshuab hluav taws xob diesel pib pib. Cov kab ke no siv ATS qeeb thiab teeb tsa qeeb (setpoints). Nws ua hauj lwm zoo li no: thaum lub hwj chim rau cov ntaub ntawv chaw los ntawm lub transformers ploj lawm, lub ATS txib cov cuab yeej: "Transformer, tua. Tam sim no peb tos 10 vib nas this (set point), diesel generator, tig rau, tos lwm 10 vib nas this.
ATS hauv UPS
Siv UPS ua piv txwv, cia saib seb hom thib ob ntawm ATS ua haujlwm li cas - STS lossis hloov pauv hloov pauv zoo li qub.
Hauv UPS, alternating tam sim no yog hloov mus rau tam sim no ncaj qha los ntawm lub rectifier. Tom qab ntawd ntawm lub inverter nws tig rov qab mus rau hauv alternating tam sim no, tab sis nrog cov tsis ruaj khov. Qhov no tshem tawm kev cuam tshuam thiab txhim kho lub zog zoo. Thaum lub ntsiab fais fab mov raug muab tua ntawm cov roj teeb thiab lub zog rau cov ntaub ntawv chaw thaum lub tshuab hluav taws xob diesel raug muab tso rau hauv kev ua haujlwm.
Tab sis yuav ua li cas yog tias ib qho ntawm cov ntsiab lus tsis ua haujlwm: lub rectifier, inverter lossis roj teeb? Hauv qhov no, txhua lub UPS muaj lub tshuab bypass, lossis bypass. Nrog nws, cov cuab yeej txuas ntxiv ua haujlwm, hla cov ntsiab lus tseem ceeb, ncaj qha los ntawm cov khoom siv hluav taws xob. Lub bypass kuj tseem siv tau thaum koj xav tau tua UPS thiab coj nws tawm mus kho.
STS nyob rau hauv UPS yog xav tau kom muaj kev nyab xeeb hloov mus rau bypass input. Nyob rau hauv luv luv, STS saib xyuas cov tswv yim thiab tso zis network tsis, tos kom lawv phim, thiab hloov nyob rau hauv kev nyab xeeb.
AVR nyob rau hauv ib lub khib
Yog li, ob lub hwj chim inputs txuas nrog lub khib. Yog tias koj cov cuab yeej muaj ob lub zog siv hluav taws xob, koj tuaj yeem txuas tau yooj yim rau PDUs sib txawv, thiab koj tsis ntshai qhov poob ntawm ib qho kev tawm tswv yim. Yuav ua li cas yog tias koj lub server muaj ib lub hwj chim?
Nyob rau hauv khib, ATS yog siv kom cov nyiaj tau los ntawm ob inputs tsis mus pov tseg. Yog tias muaj teeb meem nrog ib qho ntawm cov khoom nkag, ATS hloov lub thauj khoom mus rau lwm qhov kev tawm tswv yim.
Kev lees paub: Yog tias koj tuaj yeem ua tau, zam cov khoom siv nrog ib lub zog hluav taws xob kom tsis txhob tsim kom muaj qhov tsis ua haujlwm hauv qhov system. Tom ntej no peb yuav qhia tias qhov tsis zoo ntawm txoj kev sib txuas no yog dab tsi.
Lub luag haujlwm ntawm ATS hauv khib yog hloov cov cuab yeej siv rau kev ua haujlwm kom nrawm kom tsis muaj kev cuam tshuam hauv nws txoj haujlwm. Qhov ceev xav tau rau qhov no tau pom kev sim: tsis pub ntau tshaj 20 ms. Cia peb saib seb qhov no tau nrhiav pom li cas.
Kev ua haujlwm tsis zoo ntawm cov khoom siv server tshwm sim vim qhov hluav taws xob poob qis (vim ua haujlwm ntawm cov chaw sib txuas, kev sib txuas ntawm cov khoom muaj zog lossis kev sib tsoo). Txhawm rau ua piv txwv li cas cov cuab yeej tuaj yeem tiv taus qhov sib txawv thiab lub sijhawm ntawm qhov hluav taws xob nce siab, CBEMA (Computer and Business Equipment Manufacturers Association) cov khoom siv hluav taws xob kev nyab xeeb tau tsim. Tam sim no lawv hu ua ITIC (Information Technology Industry Council) nkhaus, lawv cov kev hloov pauv tau suav nrog IEEE 446 ANSI cov qauv (qhov no yog qhov piv txwv ntawm peb GOSTs).
Cia peb tshawb xyuas lub sijhawm. Peb txoj hauj lwm yog los xyuas kom meej tias cov cuab yeej ua haujlwm hauv "thaj chaw ntsuab". Ntawm ITIC nkhaus peb pom tias cov cuab yeej tau npaj "them" qhov poob siab tshaj plaws ntawm 20 ms. Yog li ntawd, peb tsom rau ATS hauv khib ua haujlwm hauv 20 ms, lossis zoo dua, txawm tias sai dua.
Tau qhov twg los: .
ATS ntaus ntawv. Ib tug raug ATS nyob rau hauv peb cov ntaub ntawv chaw khib occupies 1 unit thiab muaj peev xwm tiv taus ib tug load ntawm 16 A.
Ntawm cov zaub peb pom los ntawm cov tswv yim twg ATS tau siv, ntau npaum li cas cov khoom siv txuas nrog siv hauv amperes. Siv lub pob cais los xaiv seb puas yuav muab qhov tseem ceeb rau thawj lossis thib ob cov tswv yim. Ntawm sab xis yog cov chaw nres nkoj rau txuas rau ATS:
- Ethernet chaw nres nkoj - txuas saib xyuas;
- Serial chaw nres nkoj - nkag rau hauv ntawm lub laptop thiab pom dab tsi tshwm sim hauv cov cav;
- USB - ntxig lub flash drive thiab hloov kho lub firmware.
Cov chaw nres nkoj sib hloov tau: koj tuaj yeem ua txhua yam haujlwm no yog tias koj nkag mus rau yam tsawg kawg ib ntawm lawv.
Nyob rau sab nraub qaum muaj cov ntsaws rau txuas lub ntsiab thiab cov khoom siv thaub qab thiab ib pawg qhov (socket) rau kev txuas IT khoom.
Peb saib cov ncauj lus kom ntxaws ntawm AVR los ntawm lub vev xaib interface. Nyob ntawd koj tuaj yeem kho qhov hloov rhiab heev thiab pom cov cav.
AVR web interface.
Kev teeb tsa thiab kev sib txuas ntawm ATS. Nws yog qhov zoo dua rau nruab AVR hauv qhov siab hauv nruab nrab ntawm lub khib. Yog tias peb tsis paub qhov kev teeb tsa ntawm cov khib nyiab ua ntej, cov khoom siv nrog ib lub hwj huam tuaj yeem ncav cuag nrog cov xov hlau los ntawm ob qho tib si hauv qab thiab sab saum toj.
Tab sis tom qab ntawd muaj cov nuances: qhov tob ntawm tus qauv khib yog ntau dua qhov tob ntawm AVR. Peb pom zoo kom txhim kho nws kom ze rau qhov txias aisle li ua tau rau ob qho laj thawj:
- Pem hauv ntej vaj huam sib luag nkag. Yog tias peb nruab ATS ze rau ntawm txoj kab kub, peb yuav pom qhov qhia, tab sis yuav tsis tuaj yeem txuas rau nws los ntawm cov chaw nres nkoj. Qhov no txhais tau tias peb yuav tsis tuaj yeem saib cov cav lossis reboot lub cuab yeej.
Qee qhov hauv qhov tob, AVR tab tom ntsais - qhov chaw nres nkoj tsis tuaj yeem ncav cuag. - Lub tub yees. AVR tau pom zoo kom siv ntawm qhov kub tsis tshaj 45 Β° C. Txawm li cas los xij, nws tsis muaj nws tus kheej kiv cua kom txias; nws tsuas yog ib qho khoom siv hlau nrog hluav taws xob filling. Khaws qhov kub uas xav tau nyob rau hauv ob txoj kev:
- cov kwj ntawm huab cua uas tshuab los ntawm sab nraud;
- fasteners uas tshem tawm cov cua sov tshaj.
Yog tias peb nruab ATS ntawm sab ntawm txoj kab kub thiab, ntxiv rau, qhaub cij nrog lub ncuav qab zib ntawm cov servers, ces peb yuav tau txais lub qhov cub. Nyob rau hauv qhov zoo tshaj plaws, AVR yuav hlawv tawm nws lub hlwb thiab poob kev sib cuag nrog lub ntiaj teb sab nraud, nyob rau hauv qhov phem tshaj, nws yuav pib random hloov lub load los yog tso tseg.
AVR yog steaming tig rau ntawm txoj kev kub.
Muaj ib rooj plaub. Ib tug engineer ntawm nws rounds hnov ββuncharacteristic clicks.
Nyob rau hauv qhov tob ntawm txoj kev kub kub, nyob rau hauv ib pawg ntawm cov servers, ib qho ATS tau tshawb pom uas tau hloov mus tas li los ntawm cov tswv yim tseem ceeb mus rau qhov thaub qab.Lub AVR tau hloov. Cov cav tau pom tias rau ib lub lim tiam nws hloov txhua ob - tag nrho ntau tshaj li ib nrab lab hloov pauv. Yog li ntawd
Yuav ua li cas lwm yam AVRs muaj nyob rau hauv ib lub khib?
Introductory khib ATS. Nyob rau hauv peb cov ntaub ntawv chaw, xws li ATS ua raws li lub hauv paus ntawm lub hwj chim faib nyob rau hauv lub khib: nws ua hauj lwm raws li ib tug ATS + PDU. Nws nyob ob peb chav nyob, tuaj yeem tiv taus qhov hnyav ntawm 32 A, txuas nrog cov khoom siv hluav taws xob thiab tuaj yeem siv zog txog 6 kW ntawm cov khoom siv. Nws tuaj yeem siv tau thaum nws tsis tuaj yeem txhim kho tus qauv PDUs, thiab cov khoom siv ib leeg hauv lub khib tsis ua haujlwm tseem ceeb.
Rack STS. Rack-mounted STS yog siv rau cov khoom siv surge-sensitive. Qhov no ATS hloov sai dua ATS.
Qhov tshwj xeeb STS no siv li 6 units thiab muaj me ntsis "vintage" interface.
Mini-AVR. Muaj cov menyuam mos zoo li no, tab sis hauv peb lub chaw khaws ntaub ntawv qhov no tsis yog li ntawd. Qhov no yog mini-ATS rau ib lub server.
Qhov ATS no txuas ncaj qha rau lub server lub zog.
Yuav ua li cas peb nrhiav rau qhov zoo tagnrho AVR
Peb sim ntau yam ATSs thiab xyuas seb lawv coj li cas hauv qhov kub thiab txias.
Nov yog qhov peb thuam AVR los kuaj nws:
- peb txuas mus rau nws lub network zoo recorder, ib tug neeg rau zaub mov thiab ob peb yam ntxiv rau lub load;
- peb insulate lub khib nrog plugs los yog zaj duab xis kom ncav cuag kub;
- kub rau 50 Β° C;
- alternated tua cov inputs 20 zaug;
- peb saib seb puas muaj lub hwj chim tsis ua hauj lwm thiab cov neeg rau zaub mov xav li cas;
- Yog tias AVR dhau qhov kev sim, ua kom sov rau 70 Β° C.
Yees duab nrog lub thermal imager los ntawm ib qho ntawm cov kev xeem.
Lub network analyzer sau cov voltage dhau sijhawm. Nyob rau hauv cov ntaubntawv povthawj siv peb pom ntev npaum li cas lub switching kav: lub sij hawm no lub sine yoj raug cuam tshuam
Los ntawm txoj kev, peb yuav coj AVR rau kev sim: peb yuav kuaj koj lub cuab yeej kom muaj zog thiab qhia koj tias muaj dab tsi tshwm sim π
AVR hauv khib: qhov kev hem thawj zais
Qhov teeb meem tseem ceeb nrog lub khib-mounted ATS yog tias nws tsuas tuaj yeem hloov lub thauj khoom los ntawm lub ntsiab mus rau cov ntaub ntawv thaub qab, tab sis tsis tiv thaiv luv luv lossis overloads. Yog hais tias ib tug luv luv Circuit Court tshwm sim nyob rau hauv lub hwj chim mov, ces lub Circuit Court breaker nyob rau theem siab dua yuav ua hauj lwm rau kev tiv thaiv: nyob rau hauv lub PDU los yog nyob rau hauv lub tis board. Yog li ntawd, ib qho kev tawm tswv yim raug muab tua, ATS nkag siab qhov no thiab hloov mus rau qhov kev tawm tswv yim thib ob. Yog hais tias lub luv luv Circuit Court tseem nyob, qhov thib ob input Circuit Court breaker yuav mus. Yog li ntawd, ib qho teeb meem ntawm ib qho khoom siv tuaj yeem ua rau tag nrho cov khib nyiab poob.
Yog li kuv rov hais dua ib zaug ntxiv: xav txog ib txhiab zaus ua ntej txhim kho ATS hauv lub khib thiab siv cov khoom siv nrog ib lub hwj chim.
