Yuav ua li cas loj ib lub Transformer rau Data Center

Thaum xub thawj siab ib muag, sizingib tug transformer rau ib tug data centersuab yooj yim heev.
Tsuas yog ntxiv cov loads, xaiv lub transformer, ua tiav- puas yog?

Tab sis hauv lub neej tiag tiag? Feem ntau tsis yog.

Lub chaw khaws ntaub ntawv tsis coj tus cwj pwm zoo li lub tsev ua haujlwm zoo li qhov kev thov nce thiab poob thaum nruab hnub. Cov servers thiab lub tshuab hluav taws xob ua haujlwm ua haujlwm, txias yog qhov pib ntawm lub sijhawm 24/7, thiab lub zog xav tau tuaj yeem nce nrawm dua li qhov koj xav tau-tshwj xeeb tshaj yog hnub no AI workloads thiab siab - teeb tsa.

Yog litransformer sizingtsawg dua qhov koj xav tau tam sim no thiab ntau ntxiv txog yam koj xav tau tom qab. Yav tom ntej tseem ceeb. Ntau heev.

Pib nrog qhov xav tau tiag tiag

Ua ntej koj txawm saib cov kev ntsuas transformer, tsom mus rau qhov twg yog qhov siv zog hauv qhov chaw.

Feem ntau cov chaw zov me nyuam yuav ua txhaum kev siv fais fab rau hauv ob peb lub thoob loj:

• IT khoom:servers, cia, networking iav
• Cov tshuab cua txias
• Cov cuab yeej txhawb nqa:UPS (data centerUninterruptible Power Supply)systems, teeb pom kev zoo, saib xyuas, thiab lwm yam pabcuam
•  

IT load feem ntau yog tus lej yooj yim tshaj plaws kom tau txais vim tias nws ncaj qha cuam tshuam cov khoom siv ntawm qhov chaw. Kev txias tuaj yeem ua rau me ntsis messier. Nyob ntawm tus qauv tsim, cua txias ib leeg tuaj yeem ua tau30% mus rau 50% ntawm tag nrho IT load-thiab nyob rau hauv huab cua kub, nws yuav nkag siab dua.

Ib qho kev ua yuam kev (thiab nws tshwm sim ntau dua li cov neeg lees paub) yog sizing transformers raws li cov khoom siv tam sim no. Qhov ntawd yuav ua haujlwm tau ib ntus, tab sis cov chaw khaws ntaub ntawv tsis tshua nyob "raws li-yog" ntev.

Hloov Load rau hauv Transformer Capacity

Ntawm no yog qhov twist: transformers tau ntsuas hauvkVA ua, tsis

kW.

Qhov ntawd txhais tau hais tias koj yuav tsum muaj nyob rau hauvfais fab xwm txheej.

Ib qho pib xam pib zoo li no:

• kVA=kW ÷ Fais fab mov

Piv txwv:

• IT khoom:1,200 kW ntawm 0.95 PF
• Cua txias:800 kW ntawm 0.85 PF
• Kev pabcuam loads:200 kW ntawm 0.90 PF

Qhov ntawd los txog rau:

• 1,263 kVA rau IT
• 941 kVA rau cua txias
• 222 kVA rau auxiliary systems

Tag nrho? Kwv yees li2,426 kVA.

Tab sis ob peb txoj haujlwm nres ntawm tus lej huv si. UPS poob, npaj rack ntxiv, tsis xav txog kev loj hlob, thiab kev ua haujlwm cia tag nrho thawb qhov kawg transformer loj dua. Nyob rau hauv ntau zaus, nws xaus mus ze rau3,000-3,500 kVA.

Kev ntseeg tau hloov txhua yam

Honestly, redundancy yuav muaj teeb meem ntau tshaj load lej hauv transformer xaiv.

Ib qho chaw me me yuav siv lub zog hluav taws xob yooj yim dua, tab sis cov ntaub ntawv loj dua feem ntau xav tauN+1los yog2Nredundancy.

• N+1:ib qho ntxiv transformer muaj yog tias lwm chav tsev raug tshem tawm ntawm kev pabcuam
• 2N:ob txoj kev ywj pheej ywj pheej, txhua tus muaj peev xwm nqa tau tag nrho

Rau Tier III thiab Tier IV qhov chaw, qhov kev ntseeg zoo li no tsis yog "zoo" - nws yog tag nrho cov ntsiab lus, vim tias lub sijhawm poob qis tsuas yog siv tsis tau.

Harmonics Yooj yim rau saib dua-Txog lawv tsis yog

Niaj hnub nimno cov ntaub ntawv chaw yog loaded nrog nonlinear khoom. Servers, UPS systems, thiab variable -ceev drives tag nrho cov tsim harmonics. Cov kev sib haum xeeb tsis yog "muaj" xwb -lawv tsim cov cua sov ntxiv hauv transformer windings.

Thiab yog tias koj tsis quav ntsej ntev dhau lawm, koj yuav pom kev ua haujlwm qis dua thiab txo cov khoom siv lub neej. Tsis zoo.

Yog vim li casK- ntsuas transformersmuaj nyob rau hauv cov ntaub ntawv chaw ib puag ncig. Koj yuav pom ntau zausK-13los yogK-20tau teev tseg, tab sis cov lus teb tiag yog nyob ntawm qhov kev kawm sib haum xeeb thiab cov ntaub ntawv thauj khoom. (Yog li, yog-txhua qhov project txawv me ntsis.)

Qhuav-Hom lossis Roj-Immered?

Rau kev teeb tsa sab hauv tsev, ntau tus tswv lag luam lean mus raucam khwb cia resin qhuav -hom transformers. Cov laj thawj yog qhov ua tau zoo:

• kev nyab xeeb hluav taws zoo dua
• kev txij nkawm tsawg tsawg
• tsis muaj kev txhawj xeeb txog roj
• yooj yim duainstallation nyob rau hauv cov tsev
•  

Roj-cov chav nyob rau hauv dej tseem ua rau muaj kev nkag siab zoo hauv qee qhov kev siv sab nraum zoov thiab cov chaw siv hluav taws xob-tshwj xeeb tshaj yog thaum xav tau ntau dua. Tsis muaj leej twg -size- haum- teb, hmoov tsis. Nws nyob ntawm qhov chaw thiab qhov project xav tau.

Tawm ntawm Chav Rau Kev Loj Hlob

Ntawm no yog lwm yam ntaub ntawv chaw pab pawg kawm tau sai: kev thov yuav loj hlob sai dua li qhov xav tau.

Cov servers tshiab tshwm sim. Rack ceev nce. AI workloads nthuav dav.

Ib qho kev hloov pauv uas pom tau tias yooj yim loj dua niaj hnub no yuav saib qis dua tsib xyoos txij li tam sim no.

Tias yog vim li cas ntau tus neeg tsim qauv tsim lub peev xwm seem rau hauv cov phiaj xwm qub. Kev nqis peev ntxiv rau pem hauv ntej feem ntau pheej yig dua li hloov cov txheej txheem tom qab (uas tsis muaj leej twg xav ua).

Kev xav zaum kawg

Tsis muaj ib qho qauv zoo meej rau transformer sizing uas ua haujlwm rau txhua qhov chaw cov ntaub ntawv.

Yog, kev xam load yog ib qho tseem ceeb. Tab sis koj kuj yuav tsum tau them nyiaj rov qab, kev ua tau zoo sib haum xeeb, kev xav tau cua txias, lub hom phiaj ua haujlwm tau zoo, thiab ntev - cov phiaj xwm nthuav dav.

Raws li qhov piv txwv dav dav: ib qho chaw nrog ib puag ncig2 MW ntawm IT loadtej zaum yuav kawg sivOb lub transformers nyob ib ncig ntawm 3,000-3,500 kVA txhuahauv ibN+1teeb tsa. Qhov tseeb specs yuav txawv ntawm qhov project, tab sis cov ntsiab lus tseem ceeb nyob twj ywm tib yam:

Qhov loj ntawm transformer tsis tsuas yog rau hnub no lub load, tab sis rau qhov chaw ntawm qhov chaw yuav zoo li ob peb xyoos ntawm txoj kev.
