Nyob rau yav tsaus ntuj ntawm Lub Kaum Ob Hlis 9, 2019, kev yuav khoom ua ntej hnub so ntawm cov neeg tuaj saib hauv Eaton Center khw hauv Toronto tau cuam tshuam los ntawm qhov tsis xav tau. . Cov khw muag khoom tau poob rau hauv qhov tsaus ntuj, thiab tib lub teeb ntawm lub teeb yog tsob ntoo Christmas - ntau tus tau maj nrawm tshaj tawm nws cov duab hauv kev tes hauj lwm raws li qhov tshwm sim tsis meej. Txawm li cas los xij, ntawm cov tweets muaj cov uas qhov mysticism tau piav qhia yooj yim thiab yooj yim: tsob ntoo tau txuas nrog lub zog tsis cuam tshuam. Niaj hnub no peb yuav tham txog qhov twg UPS cov neeg xauj tsev tuaj yeem siv los npaj cov khoom siv hluav taws xob tsis cuam tshuam rau lawv thaj chaw hauv khw muag khoom. Tom qab tag nrho, kev yuav khoom yuav tsum mus ntxiv, puas yog?
Guaranteed thiab uninterrupted fais fab mov
Tab sis ua ntej, cia peb hais tias vim li cas qhov teeb meem hluav taws xob ntawm Eaton Center khw hauv Toronto tau suav nrog hauv lub npe ntawm tsab xov xwm. Peb tab tom tham txog lub npe kos npe; qhov chaw yuav khoom no tsis muaj kev cuam tshuam nrog lub tuam txhab tsim khoom Eaton. Yooj yim Eaton yog ib lub npe nrov ntawm cov neeg muaj peev xwm tsiv teb tsaws chaw uas tuaj txog hauv Tebchaws Meskas los ntawm British Isles thaum tig ntawm XNUMXth thiab XNUMXth centuries. Ib qho ntawm Eatons tau tsim ib lub tuam txhab lag luam, thiab lwm tus tau tsim lub tuam txhab engineering. Tam sim no cia peb rov qab mus rau lub ntsiab lus tseem ceeb.
Lub khw muag khoom yog ib qho chaw ua haujlwm nyuaj nyob rau hauv cov nqe lus ntawm kev ua kom muaj kev lav phib xaub thiab tsis muaj kev cuam tshuam. Raws li koj paub, kev tswj hwm ntawm txhua lub khw muag khoom npaj yuav xauj qhov chaw tsis muaj chaw rau yuav luag txhua tus neeg xauj tsev, tsuav yog lawv txoj kev lag luam nyob hauv kev cai lij choj. Nws tuaj yeem mus rau qhov chaw uas lub tsev noj mov nrog lub qhov cub hluav taws xob muaj zog lossis lub khw muag ntses nrog cov tub yees txias tam sim ntawd tshwm sim nyob rau hauv qhov chaw ntawm lub khw muag khaub ncaws kaw. Hauv lwm lo lus, qhov thauj khoom ntawm daim phiaj hluav taws xob tuaj yeem hloov pauv ntau zaus thiab yuav luag tsis tuaj yeem xav txog.
Nyob rau hauv xws li mob, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm guaranteed thiab uninterruptible fais fab mov.
lav yog ib hom khoom siv hluav taws xob uas, ntxiv rau qhov chaw nruab nrab ntawm lub zog hluav taws xob, siv cov khoom siv hluav taws xob rov qab (feem ntau yog lub tshuab hluav taws xob diesel, lub tshuab hluav taws xob diesel). Cov khw loj loj tuaj yeem ua haujlwm los ntawm ntau lub tshuab hluav taws xob diesel. Nrog guaranteed fais fab mov, ib tug so nyob rau hauv lub hwj chim mov rau cov neeg siv khoom los ntawm lub hauv paus fais fab daim phiaj tsuas yog tso cai rau lub sij hawm ntawm lub automatic hloov ntawm lub hwj chim backup (DGS, roj generator).
Tsis cuam tshuam Lub zog hluav taws xob xav tias muaj qhov thib peb lub zog hluav taws xob nyob rau hauv daim ntawv ntawm UPS, uas ua rau cov neeg siv khoom muaj zog rau lub sijhawm xav tau los pib lub tshuab hluav taws xob tswj hwm tus kheej thiab ncav cuag qhov ntsuas ntsuas. Nws feem ntau yuav siv li 3 feeb los pib lub tshuab hluav taws xob muaj zog hauv lub tshuab hluav taws xob; nyob rau lub caij ntuj no, lub coolant nyob rau hauv lawv yog tas li rhuab rau kev ntseeg siab pib.

Raws li txoj cai, lub hwj chim ntawm lub khw muag khoom yog tsim raws li cov txheej txheem classical ntawm kev faib cov neeg xauj tsev thiab cov kev pabcuam sab hauv ntawm lub khw mus rau ntau pawg ntawm cov neeg siv khoom.
- Cov neeg tau txais kev pab II qeb, uas suav nrog feem ntau ntawm cov neeg xauj tsev zoo tib yam ntawm lub khw muag khoom, tsis muaj kev sib txuas nrog kev lav phib xaub los ntawm lub tshuab hluav taws xob diesel thiab tsuas yog tso siab rau lub nroog fais fab tuag thiab lawv tus kheej (hauv zos) cov khoom siv hluav taws xob tsis cuam tshuam (UPS).
- Cov neeg tau txais kev pab Qeb I cia li hloov mus rau lub tshuab hluav taws xob diesel tau teeb tsa thaum muaj xwm txheej ceev ntawm lub nroog lub zog hluav taws xob, tab sis kom txog thaum lub tshuab hluav taws xob diesel pib, lawv yuav raug de-energized. Rau cov neeg xauj tsev, hluav taws xob hluav taws xob yog qhov tseem ceeb rau kev lag luam lossis kev nyab xeeb rau pej xeem. Hauv ib lub khw, cov neeg xauj tsev feem ntau suav nrog cov khw muag tshuaj nrog lub tub yees rau cov tshuaj, chaw kho mob thiab kho hniav, thiab chaw so rau menyuam yaus.
- Cov neeg tau txais kev pab Kuv qeb tshwj xeeb tau txais cov khoom siv hluav taws xob tsis cuam tshuam thiab tsis tuaj yeem muab tua txawm tias lub sijhawm luv luv. Rau cov neeg siv khoom zoo li no, peb qhov chaw siv hluav taws xob tau siv - lub nroog substation thiab lub tshuab hluav taws xob diesel teeb, thiab thaum pib ntawm lub tshuab hluav taws xob diesel lawv tau siv los ntawm UPSs. Cov neeg siv khoom zoo li no suav nrog lub tswb hluav taws kub thiab tsis siv neeg tua hluav taws, kev tiv thaiv pej xeem thiab kev ceeb toom xwm txheej ceev, teeb pom kev kub ceev, thaj chaw thiab khoom siv ntawm lub khw muag khoom xa khoom. Yog tias cov tuam txhab IT xauj qhov chaw nyob hauv lub khw, lawv kuj xaj kom tsis muaj kev cuam tshuam rau lawv tus kheej.
Kev siv UPS kev lag luam hauv khw muag khoom rau ib pawg tshwj xeeb ntawm cov neeg siv khoom yog ua raws li lub hauv paus txheej txheem. Nyob rau hauv cov tswv yim no, hluav taws xob yog muab los ntawm ib qhov chaw rau tag nrho cov neeg tau txais kev pab ntawm pawg no nyob rau hauv lub khw.
Rau cov neeg xauj tsev zoo tib yam ntawm lub khw muag khoom - khw, cafes, gyms, salons zoo nkauj, thiab lwm yam, muab lub hauv paus lav los yog tsis muaj kev cuam tshuam fais fab yuav yog qhov kev xaiv kim heev. Hauv cov xwm txheej zoo li no, nws muaj peev xwm ua tau nyiaj txiag los siv lub npe hu ua decentralized uninterruptible power supply scheme, uas yuav tau tham hauv qab no.
Decentralized UPS tswvyim - qhov zoo thiab qhov tsis zoo
Decentralized thiab centralized uninterruptible fais fab mov schemes tsis yog kev sib koom ua ke. Ob lub tswv yim no tuaj yeem thiab yuav tsum tau ua ke. Piv txwv li, cov neeg siv khoom tseem ceeb (ntxiv rau cov neeg uas tau them tshwj xeeb) hauv lub khw muag khoom muaj kev tiv thaiv los ntawm cov lag luam loj UPSs, tab sis hauv ib lub khw tshwj xeeb uas tsis muaj kev lees paub lub zog, nkag mus rau theem thiab nruab nrab UPSs tuaj yeem siv hauv zos los muab kev tiv thaiv. rau kev sau nyiaj ntsuab, servers, tshuab luam ntawv, thiab lwm yam.
Cia peb saib qhov zoo thiab qhov tsis zoo ntawm kev faib hluav taws xob hluav taws xob thiab, ua ntej, hais txog qhov zoo ntawm kev siv UPSs hauv zos:
- tsis tas yuav muaj cov kab txuas tshiab, cov phab ntsa uas twb muaj lawm siv; UPSs hauv zos tau yooj yim rau kev ua haujlwm thiab txuas mus rau cov ntawv sau nyiaj ntsuab, khoos phis tawj, thiab lwm yam khoom siv tseem ceeb; Thaum hloov qhov chaw xauj tsev, UPSs no raug coj mus nrog lawv thiab xa mus rau qhov chaw tshiab;
- Hauv zos nkag-theem thiab nruab nrab-chav kawm UPSs muaj tus nqi qis - cov peev nyiaj ntawm yuav luag txhua lub lag luam me tuaj yeem them taus qhov kev yuav khoom ntawm UPSs - thiab lub zog txog li 3000 VA tso cai rau koj los txuas ob peb lub npe nyiaj ntsuab lossis PCs rau ib qho UPS;
- tus neeg xauj tsev tsis khi rau qib ntawm cov khoom thauj khoom, kev hloov pauv ntawm cov ntawv sau nyiaj ntsuab lossis lwm yam khoom siv vim kev nthuav dav kev lag luam yuav tsis xav tau kev pom zoo tshiab ntawm daim ntawv cog lus hluav taws xob;
- Yog tias tus neeg xauj tsev twb tau teeb tsa lawv tus kheej UPSs, ces nws yog qhov tsim nyog los siv lawv nyob rau hauv ib qho kev faib hluav taws xob uas tsis muaj kev cuam tshuam.
Qee lub sij hawm kev tswj hwm ntawm lub khw muag khoom - tshwj xeeb tshaj yog tias muaj peev xwm pub dawb tom qab tus neeg xauj tsev tseem ceeb tau tsiv tawm - pib pheej muab cov neeg xauj tsev txuas mus rau lub network ntawm kev lees paub lossis tsis muaj kev cuam tshuam txog hluav taws xob thaum muaj hluav taws xob tawm ntawm lub nroog substation.
Nov yog thaum nws zoo dua los siv centralized uninterruptible fais fab mov:
- Kev lag luam txuas ntxiv yog qhov tseem ceeb rau tus neeg xauj tsev (piv txwv li, khw muag tshuaj nrog lub tub yees rau cov tshuaj, chaw kho mob thiab kho hniav, chaw kho mob zoo nkauj nrog cov txheej txheem txuas ntxiv mus, cov neeg xauj tsev muab kev pabcuam online, xws li cov tuam txhab IT): centralized uninterrupted fais fab mov yog tsim los rau unlimited mov. lub sijhawm cov neeg siv khoom (xws li cov khoom siv roj rau lub tshuab hluav taws xob diesel), thiab UPS hauv zos tuaj yeem txhawb nqa kev ua haujlwm ntawm cov cuab yeej siv rau lub sijhawm luv luv, feem ntau tsis pub dhau 15-20 feeb, thiab yog tias cov khoom siv hluav taws xob tsis rov qab los thaum lub sijhawm. lub sijhawm no, cov cuab yeej tseem yuav tsum tau muab tua;
- Yog hais tias tus naj npawb ntawm UPSs hauv zos tshaj ib lub kaum os, thiab lawv yog cov qauv sib txawv thiab yuav khoom ntawm lub sijhawm sib txawv, tom qab ntawd saib xyuas cov teeb meem ntawm cov roj teeb thiab hloov lawv dhau los ua qhov tsis txaus ntseeg, nws yooj yim tsis pom lub roj teeb uas twb muaj lawm, thiab ua ib qho kev tsis txaus siab. qhov tshwm sim, UPS yuav tsis tuaj yeem tiv thaiv cov khoom siv thaum muaj hluav taws xob tsis ua haujlwm;
- Thaum muaj hluav taws xob hluav taws xob, ntau lub suab ceeb toom los ntawm UPSs hauv zos tuaj yeem ua rau khaus thiab ntxhov siab rau cov neeg tuaj xyuas (piv txwv li, cov neeg siv khoom hauv tsev kho mob zoo nkauj).
Tom ntej no - hais txog cov hom thiab cov qauv ntawm UPS uas yog qhov zoo tshaj plaws rau cov neeg xauj khoom hauv khw los ntawm cov lag luam me.
Cov lus pom zoo ntawm hom thiab lub zog ntawm UPS rau cov neeg xauj khoom hauv khw
Ib zaj dab neeg hais txog peb hom UPS - offline UPS, kab-kev sib tham hom thiab online UPS - tuaj yeem pom nyob rau hauv yuav luag txhua kab lus ntawm cov ncauj lus no, tab sis koj tsis tuaj yeem ua tsis tau yog tias koj muab lus qhia txog kev xaiv cov khoom siv hluav taws xob tsis cuam tshuam.

Qhov yooj yim thiab pheej yig tshaj thaub qab UPS (offline, back-UPS, stand-by) nyob rau hauv ntau rooj plaub tsis pom zoo vim qhov tseeb hais tias qhov voltage nkag los ntawm lub network yog ncaj qha mus rau lub load. Txawm hais tias qhov voltage hauv thaub qab UPSs yog lim, nws tsis raug tswj nyob rau hauv ib txoj kev - yog hais tias muaj tsawg los yog high voltage nyob rau hauv lub network, ces qhov no yog raws nraim li cas yuav muab rau lub load.
Roj teeb lub hwj chim hauv thaub qab UPSs tsuas yog qhib thaum muaj qhov ua tiav ntawm qhov hluav taws xob tsis zoo ntawm cov tswv yim, thiab qhov kwv yees (kwv yees) daim ntawv ntawm qhov hluav taws xob sine yoj tau muab rau cov zis, uas muaj kev cuam tshuam tsis zoo rau kev ua haujlwm ntawm cov khoom siv nrog. transformer fais fab mov, hluav taws xob motors, chokes, Hi-Fi suab thiab video khoom, cua sov boilers nrog ncig twj tso kua mis, tub yees thiab cua txias, dej twj. Nws yog nruj me ntsis txwv tsis pub siv cov thaub qab UPSs los tiv thaiv cov cuab yeej kuaj thiab cov cuab yeej kho mob, uas tsuas yog siv tau los ntawm qhov hluav taws xob nrog qhov zoo tshaj plaws sinusoid.
Line-interactive UPS (kab-kev sib tham sib) - qhov ua tau zoo tshaj plaws nyob rau hauv cov nqe lus ntawm tus nqi / zoo piv ntawm lub hwj chim mov. Ib qho tseem ceeb sib txawv ntawm kab-kev sib tham UPS thiab offline UPS yog muaj qhov muaj zog stabilizer (tseem hu ua autotransformer, AVR, Automatic Voltage Regulator). Yog li ntawd, ib kab-kev sib tham UPS yog qhov tseem ceeb tshaj plaws thaum siv nyob rau hauv ib puag ncig uas cov input voltage tuaj yeem sib txawv. Lub peev xwm ruaj khov ntawm cov UPSs yog qhov tseem ceeb heev - los ntawm 150-160 V rau 270-290 V ntawm cov tswv yim, nyob ntawm tus qauv, thaum cov zis yuav ruaj khov 230 V. Cov kab niaj hnub sib tham sib UPSs, xws li Eaton 5P thiab 5PX series, muaj microprocessor tswj thiab muab qhov zoo tshaj plaws sine yoj ntawm cov zis voltage.
Online UPS (online, ob chav hloov dua siab tshiab) - qhov tseeb ntawm qhov offline UPS nyob rau hauv cov nqe lus ntawm lub hwj chim zoo: tsis hais qhov voltage los yog cuam tshuam rau hauv lub hwj chim mov, ib tug zoo tagnrho sine yoj yuav muab rau lub load. Ib qho kev hloov dua siab tshiab yog ua nyob rau hauv UPS - qhov hloov pauv input voltage yog hloov mus rau hauv qhov hluav taws xob ncaj qha, thiab tom qab ntawd rov mus rau qhov hloov hluav taws xob, nrog rau qhov tsis zoo. Qhov tsis zoo ntawm UPS online tsuas yog tus nqi siab.
Eaton pom zoo cov qauv hauv qab no ntawm kab sib tham sib UPS rau cov neeg xauj khoom hauv khw:
