RPP nyob rau hauv Data Center: Yuav ua li cas tej thaj chaw deb Fais fab Vaj Huam Sib Luag Influence Transformer xaiv thiab Fais fab faib

Thaum tib neeg xav txog lub tshuab hluav taws xob hauv ibdata center, cov neeg raug liam ib txwm los rau hauv siab -transformers,UPSunits, backup generators. Thiab ncaj ncees? Qhov ntawd ua rau kev nkag siab. Cov no yog cov khoom loj, flashy cov khoom uas ua kom lub teeb rau.

 

 

Tab sis muaj lwm yam uas ntsiag to ua ntau ntawm kev nqa hnyav ib hnub rau ib hnub: Lub Chaw Taws Teeb Hluav Taws Xob, lossis RPP.

 

Tam sim no, RPP tsis hloov voltage. Nws tsis tshua muaj lub hnub qub ntawm cov yeeb yam hauv chav fais fab. Tab sis nws yog ib feem tseem ceeb ntawm yuav ua li cas lub hwj chim tau txais qhov twg nws yuav tsum mus. Qhov tseeb, qhov koj tsim thiab tso koj RPPs tuaj yeem cuam tshuam ncaj qha rau -zoo, nws tuaj yeem cuam tshuam rau kev hloov pauv, kev ua haujlwm sib raug zoo, thiab txawm tias yooj yim npaum li cas koj tuaj yeem nthuav dav tom qab.

 

Yog li, RPPs thiab transformers ua haujlwm sib txawv heev. Tab sis lawv muaj kev sib txuas ntau dua li ntau tus neeg paub.

 

 

 

Muab qhov yooj yim, RPP yog lub zog hluav taws xob thib ob. Nws siv hluav taws xob los ntawm tus dej ntwsPDUthiab pub nws mus rau ntau lub server racks.

 

Tsis txhob khiav cov cables thoob plaws qhov chaw los ntawm ib qho chaw nruab nrab, koj siv RPPs coj lub zog los ze zog rau koj lub iav IT. Qhov ntawd ua rau tag nrho cov txheej txheem hluav taws xob huv si, kev sib koom ua ke ntau dua, thiab - tseem ceeb - yooj yim los ntsuas raws li koj qhov chaw loj hlob.

 

Ib yam RPP handles:

 Siv lub zog tawm mus rack loads

 Tiv thaiv ceg circuits

 Saib xyuas kev siv zog

 Ua rau yav tom ntej expansion yooj yim dua

 Ua kom muaj kev tswj xyuas kab mob zoo

 

Nws tsis zoo li ntau. Tab sis nyob rau hauv ib tug loj cov ntaub ntawv chaw nrog ntau pua los yog txhiab tus racks? RPPs yog qhov tseem ceeb rau kev tswj hwm cov khoom.

 

 

Ntawm no yog ib txoj hauv kev siv hluav taws xob hauv ib lub chaw khaws ntaub ntawv:

Utility Grid → Nruab nrab Voltage Switchgear → Fais fab Transformer → UPS → PDU →RPP→ Rack PDU → Servers

 

Saib ntawm cov saw hlau ntawd, koj tuaj yeem pom RPP zaum zoo nkauj ze rau cov khoom siv IT tiag tiag. Tab sis txhua qhov me me ntawm lub zog ntws los ntawm lub vaj huam sib luag no los ntawm cov dej ntws mus los- pib nrog lub transformer.

 

Yog vim li cas transformer engineers yeej mob siab heev txog RPP xa mus. Muaj pes tsawg panels? Lawv txhawb nqa dab tsi? Qhov kev npaj loj hlob yog dab tsi? Tag nrho cov kev cuam tshuam uas transformer koj xaiv.

 

Ntawm no yog qhov -sizing lub transformer tsis yog tsuas yog ntxiv rau hnub no lub loads thiab hu nws ua tiav.

 

Feem ntau cov chaw zov me nyuam yog tsim nrog kev loj hlob hauv siab. Lub tsev ntaub ntawv uas yog ib nrab khoob hnub no? Hauv ob peb xyoos, nws tuaj yeem ua tiav.

Cia peb ua piv txwv ceev:

Tab sis qhov ntawd tsuas yog ib feem ntawm zaj dab neeg. Koj kuj yuav tsum xav txog:

 Yav tom ntej expansion

 Kev xav tau redundancy

 UPS poob

 Load ntau haiv neeg

 Ntev - kev npaj peev txheej

 

Yog li, ib qho chaw nrog 2,250 kVA ntawm kev suav load yuav xaus rau kev txhim kho2,500 kVA- lossis txawm tias 3,000 kVA-transformer. Vim tias thaum cov racks tshiab pib tshwm sim sai dua li qhov xav tau, me ntsis ntxiv peev xwm mus ntev.

 

Yog lawm, tam sim no cia peb nkag mus rau hauv cov nroj tsuag me ntsis.

 

Feem ntau cov iav ntsaws rau hauv RPPs siv hloov-hom fais fab mov (SMPS). Lawv ua haujlwm tau zoo, paub meej-tab sis lawv kuj cuam tshuam nrog koj lub zog zoo los ntawm kev qhia txog kev sib haum xeeb tam sim no.

 

Common culprits:

 Cov servers

 Cov tshuab khaws cia

 Network keyboards

 Blade servers

 AI thiab GPU pawg

 

Es tsis txhob kos ib tug zoo, du waveform tam sim no, cov loads tsim kev sib haum xeeb uas rov qab los ntawm kev faib network thiab ntaus koj lub transformer.

Nyob rau tib lub sijhawm, ntau yam kev sib haum xeeb tuaj yeem ua rau:

 Siab dua transformer poob

 Kev ua haujlwm kub

 Ntxiv kev ntxhov siab ntawm rwb thaiv tsev

 Tsawg efficiency

 Cov cuab yeej siv lub neej luv dua

 

Tsis yog raws nraim qhov koj xav tau hauv lub hom phiaj - qhov chaw tseem ceeb.

 

Vim hais tias harmonics yog zoo nkauj npaum li cas yuav zam tsis tau hnub no, ntau cov ntaub ntawv chaw mus nrogK- ntsuas transformers. Cov no yog tsim los tswj cov cua sov ntxiv los ntawm cov tsis yog -linear loads.

Qhov siab dua qhov K- ntsuam xyuas, qhov zoo dua lub transformer tuav harmonics yam tsis ua noj nws tus kheej. Thiab nrog AI workloads tawg, K-20 thiab K-30 transformers yog txoj kev ntau dua tam sim no tshaj li ob peb xyoos dhau los.

 

 

Qee zaum tuav harmonics tsis txaus. Hauv cov chaw loj dua, koj xav tautxolawv ntawm qhov chaw.

 

Qhov ntawd yog qhov twgHarmonic Mitigating Transformers (HMTs)tuaj rau hauv. Lawv siv cov kev npaj tshwj xeeb winding thiab theem- hloov kev ua kom yuam kev kom tshem tawm qee yam kev sib haum xeeb ua ntej lawv kis tau los ntawm koj lub cev.

Rau siab -cov ntaub ntawv ceev ceev, HMTs tuaj yeem yog txoj hauv kev zoo los txhawb kev ntseeg siab thiab lub zog zoo.

 

 

Rau cov chaw zov me nyuam niaj hnub,qhuav - hom transformersfeem ntau yog mus - mus. Nov yog vim li cas:

Cam khwb cia resin qhuav -hom transformersmuab kev ua haujlwm tua hluav taws zoo rau koj, kev saib xyuas qis, thiab haum rau hauv tsev. Yog vim li cas lawv thiaj siv thoob plaws lub ntiaj teb no hauv lub hom phiaj- cov chaw tseem ceeb.

 

 

Thaum xub thawj siab ib muag, RPP zoo li tsuas yog lwm lub vaj huam sib luag. Tab sis nws yeej ua lub luag haujlwm loj dua hauv koj lub chaw cov ntaub ntawv hluav taws xob tsim dua li cov neeg feem coob paub.

 

Txhua qhov kev sib txuas los ntawm RPP cuam tshuam rau lub peev xwm ntawm lub tshuab hluav taws xob, qib kev sib haum xeeb, thiab kev ua haujlwm ntev -. Thiab raws li khib nyiab nce ntxiv -thiab AI tsav lub zog xav tau ntau dua - cov kev sib txuas no tseem ceeb dua li qub.

 

Xaiv qhov zoo transformer (K- ntsuas, harmonic mitigating, los yog siab -efficiency dry-type)) pab kom cov khoom ntseeg tau niaj hnub no, thaum tawm hauv chav kom loj hlob tag kis.

 

Thaum kawg, lub zog xa hluav taws xob zoo tsis yog kev txav hluav taws xob xwb. Nws yog hais txog kev ua kom muaj kev nyab xeeb, ua tau zoo, thiab tsis tu ncua- xyoo dhau los.
