Cov yam ntxwv ntawm UPS rau cov chaw ua haujlwm

Uninterrupted fais fab mov yog ib qho tseem ceeb ob qho tib si rau ib tug neeg lub tshuab nyob rau hauv ib tug industrial enterprise thiab rau ib tug loj ntau lawm complex raws li tag nrho. Cov tshuab hluav taws xob niaj hnub no yog qhov nyuaj thiab txhim khu kev qha, tab sis lawv tsis tas yuav tiv nrog txoj haujlwm no. Dab tsi ntawm UPS yog siv rau cov chaw tsim khoom? Lawv yuav tsum ua li cas? Puas muaj tej yam kev ua haujlwm tshwj xeeb rau cov khoom siv li no?

Yuav tsum muaj rau industrial UPS

Ua raws li lub hom phiaj, peb tuaj yeem hais txog cov yam ntxwv tseem ceeb uas cov khoom siv hluav taws xob tsis cuam tshuam rau cov chaw tsim khoom yuav tsum muaj:

• Siab zog tso zis. Nws yog txiav txim siab los ntawm lub zog ntawm cov khoom siv hauv kev lag luam.
• Kev ntseeg siab tshaj plaws. Nws yog nteg nyob rau theem ntawm kev tsim cov qauv ntawm qhov chaw. Hauv lawv cov khoom siv, cov khoom siv tau siv los ua kom muaj kev ntseeg siab ntawm cov khoom siv. Qhov no, ntawm chav kawm, nce tus nqi ntawm UPS, tab sis tib lub sij hawm nce lub neej kev pab cuam ntawm ob qho tib si ntawm lawv tus kheej thiab cov khoom siv uas lawv muab hluav taws xob.
• Ib qho kev xav zoo tsim uas pab txhawb kev kuaj mob, kev saib xyuas thiab kho cov khoom siv hluav taws xob tsis cuam tshuam. Txoj hauv kev no muab kev nkag tau yooj yim rau txhua qhov system units thiab txo lub sij hawm uas yuav tsum tau disassemble los yog hloov UPS Cheebtsam.
• Muaj peev xwm scaling thiab du nce zog. Qhov no yog qhov tsim nyog thaum xav tau hluav taws xob nce.

Hom kev lag luam UPS

Muaj peb yam tseem ceeb ntawm cov khoom siv hluav taws xob tsis cuam tshuam siv rau kev lag luam:

1. Reserve (lwm lub npe hu ua Off-Line lossis Standby). Xws li cov peev txheej tau nruab nrog lub tshuab hluav taws xob tsis siv neeg, uas, thaum lub zog tsis ua haujlwm, hloov cov khoom thauj mus rau cov roj teeb. Cov no yog cov txheej txheem yooj yim thiab pheej yig, tab sis lawv tsis tau nruab nrog lub network voltage stabilizers (uas txhais tau hais tias cov roj teeb hnav sai dua) thiab xav tau qee lub sijhawm hloov hluav taws xob rau cov roj teeb (kwv yees li 4 ms). Xws li UPSs tsuas yog tiv nrog hluav taws xob luv luv thiab siv los ua cov khoom siv tsis tseem ceeb.
2. Kab-kev sib tham sib. Cov chaw zoo li no tau nruab nrog cov transformers kom ruaj khov cov zis voltage. Raws li qhov tshwm sim, tus naj npawb ntawm cov khoom siv hluav taws xob hloov mus rau cov roj teeb raug txo thiab lub roj teeb lub neej tau txais kev cawmdim. Txawm li cas los xij, UPSs tsis yog tsim los lim suab nrov thiab tswj qhov hluav taws xob waveform. Lawv yog qhov zoo tshaj plaws rau cov khoom siv hluav taws xob tsis cuam tshuam rau cov khoom siv uas tsuas yog cov khoom siv hluav taws xob tseem ceeb.
3. Hauv online (On-Line). Nyob rau hauv xws li qhov chaw, ob chav voltage conversion tshwm sim. Ua ntej, los ntawm kev hloov mus rau ncaj qha (nws yog muab rau cov roj teeb), thiab tom qab ntawd rov qab mus rau qhov hloov pauv, uas yog siv los ua cov khoom siv hluav taws xob. Nyob rau hauv cov ntaub ntawv no, tsis tsuas yog tus nqi voltage yog tswj kom meej meej, tab sis kuj cov theem, zaus thiab amplitude ntawm lub alternating tam sim no. Qee cov tuam txhab lag luam, tsis txhob hloov dua siab tshiab, siv bidirectional inverters, uas hloov pauv ua haujlwm ntawm lub rectifier lossis lub inverter. Online UPSs txuag lub zog thiab yog tus cwj pwm los ntawm kev ua haujlwm tau zoo. Cov peev txheej zoo li no tsim nyog rau kev tiv thaiv cov cuab yeej muaj zog thiab lub network-rhiab heev.

Tsis tas li ntawd, kev lag luam UPS tuaj yeem muab faib ua ob pawg nyob ntawm hom kev thauj khoom:

• Thawj suav nrog cov khoom siv hluav taws xob tsis cuam tshuam, uas yog siv los tiv thaiv cov txheej txheem tsim khoom thiab cov khoom siv ua haujlwm los ntawm hluav taws xob tawm. Rau lub hom phiaj no, thaub qab lossis kab sib tham sib UPS tuaj yeem siv tau.
• Qhov thib ob suav nrog UPSs, uas yog siv rau lub zog tsis cuam tshuam rau IT infrastructure: cov ntaub ntawv khaws cia lossis cov servers. On-Line hom qhov chaw tsim nyog rau qhov no.

Kev khiav hauj lwm tej yam kev mob rau industrial UPSs

Kev lag luam hauv kev lag luam sib txawv muaj lawv tus kheej tshwj xeeb, thiab yog li ntawd muaj cov kev cai sib txawv rau cov khoom siv hluav taws xob tsis cuam tshuam. Qhov tseeb, txhua qhov haujlwm zoo li no yog qhov tshwj xeeb thiab xav tau kev txhim kho cov cuab yeej siv rau nws cov xwm txheej. Nov yog qee qhov piv txwv ntawm kev tsim khoom tshwj xeeb:

• UPS, siv nyob rau hauv cov roj refineries los xyuas kom meej kev ruaj ntseg ntawm distillation txhua, yog siv los muab kev kub ceev fais fab mov tsis tsuas yog rau kev tswj systems, tab sis kuj rau actuators. Raws li, lawv yuav tsum muaj lub zog siab.
• Geothermal zog nroj tsuag tsim ib tug byproduct: sulfur dioxide gas. Thaum nyob rau hauv kev sib cuag nrog atmospheric noo noo, nws tsim sulfuric acid vapors. Nws tuaj yeem rhuav tshem cov ntaub ntawv siv los ua cov khoom siv hluav taws xob tsis cuam tshuam.
• Ntawm ntug hiav txwv roj platforms, lwm qhov txaus ntshai yog nce av noo, ntsev thiab muaj peev xwm ntawm kab rov tav lossis ntsug txav ntawm lub hauv paus uas UPS tau teeb tsa.
• Smelting nroj tsuag muaj zog electromagnetic teb uas yuav ua rau cuam tshuam thiab mus txawv tebchaws qhov chaw Circuit Court breakers.

Cov npe saum toj no tuaj yeem ntxiv nrog ntau ntau lwm yam piv txwv. Nyob rau tib lub sijhawm, tsis hais txog qhov tshwj xeeb ntawm kev lag luam kev lag luam, cov khoom siv hluav taws xob tsis cuam tshuam yuav tsum tau ua haujlwm zoo rau 15-25 xyoo. Peb tuaj yeem txheeb xyuas ob yam tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm UPS:

1. Chaw nyob. Nws yog nruj me ntsis txwv tsis pub muab qhov chaw nyob ze cov neeg siv khoom siv hluav taws xob. Lawv yuav tsum raug tiv thaiv los ntawm qhov kub thiab txias, huab cua tsis zoo los yog kev cuam tshuam rau cov neeg kho tshuab. Rau UPSs, qhov zoo tshaj plaws kub yog 20-25 ° C, tab sis lawv tseem ua haujlwm zoo ntawm qhov kub txog li 45 ° C. Kev nce ntxiv hauv roj teeb lub neej luv luv lub roj teeb lub neej vim tias tag nrho cov txheej txheem tshuaj hauv lawv tau nrawm dua.

   Cov huab cua plua plav kuj tsim teeb meem. Cov plua plav zoo ua raws li abrasive thiab ua rau hnav ntawm qhov chaw ua haujlwm ntawm cov kiv cua thiab tsis ua haujlwm ntawm lawv cov bearings. Koj tuaj yeem sim siv UPSs yam tsis muaj kiv cua, tab sis nws muaj kev nyab xeeb ntau dua los tiv thaiv lawv los ntawm cov kev cuam tshuam zoo li no. Txhawm rau ua qhov no, cov cuab yeej yuav tsum tau muab tso rau hauv ib chav sib cais nrog kev tswj xyuas qhov kub thiab txias.

2. Hluav taws xob rov qab. Lub tswv yim heev ntawm kev xa rov qab qee qhov hluav taws xob rau hauv daim phiaj thiab rov siv nws yog qhov tseem ceeb. Nws tso cai rau koj txo cov nqi hluav taws xob. Cov txheej txheem rov qab siv tau nquag siv, piv txwv li, hauv kev thauj mus los hauv kev tsheb ciav hlau, tab sis lawv muaj kev phom sij rau cov khoom siv hluav taws xob tsis cuam tshuam. Thaum siv hluav taws xob rov qab, DC tsheb npav voltage nce. Yog li ntawd, kev tiv thaiv tau tshwm sim thiab UPS hloov mus rau hom bypass. Cov txiaj ntsig ntawm kev rov qab tsis tuaj yeem raug tshem tawm tag nrho. Lawv tsuas tuaj yeem txo qis los ntawm kev siv cov khoom siv hluav taws xob hloov pauv tsis cuam tshuam.
