Xaiv Transformers rau Cov Chaw Khaws Ntaub Ntawv

Nyob rau hauv lub caij nyoog ntawm kev hloov pauv digital, cov chaw khaws ntaub ntawv tau dhau los ua lub plawv ntawm cov tuam txhab, thiab cov transformers yog cov khoom siv tseem ceeb uas ua rau lub siab no dhia. Kev xaiv lub transformer zoo tsis yog tsuas yog cuam tshuam nrog kev siv hluav taws xob zoo thiab cov nqi ua haujlwm ntawm lub chaw khaws ntaub ntawv xwb tab sis kuj cuam tshuam ncaj qha rau kev lag luam txuas ntxiv mus thiab kev ruaj ntseg ntawm cov ntaub ntawv.

Kev xaiv cov transformers rau cov chaw khaws ntaub ntawv loj yuav tsum xav txog ntau lub hauv paus ntsiab lus suav nrog lub peev xwm thauj khoom, kev ua haujlwm zoo thiab kev siv hluav taws xob, kev ruaj khov, kev ntseeg tau, thiab kev hloov pauv tau. Raws li cov khoom siv tseem ceeb ntawm lub zog fais fab, kev xaiv thiab kev teeb tsa ntawm cov transformers cuam tshuam ncaj qha rau kev ua haujlwm ruaj khov ntawm tag nrho cov chaw khaws ntaub ntawv.

Tsab xov xwm no yuav piav qhia txog cov yam tseem ceeb uas yuav tsum xav txog thaum xaiv cov transformers uas tsim nyog rau cov chaw khaws ntaub ntawv los pab koj txiav txim siab zoo.

1. Cov Kev Cai Tshwj Xeeb rau Cov Chaw Hloov Kho Data Center

Cov chaw khaws ntaub ntawv muaj qhov xav tau hluav taws xob ntau heev. Lub nra hnyav feem ntau muaj cov khoom siv hluav taws xob xws li cov servers, cov khoom siv khaws cia, thiab cov khoom siv pabcuam xws li cua txias thiab cua txias. Txhawm rau kom tsis txhob muaj kev cuam tshuam los ntawm cua txias thiab cua txias ntawm cov khoom siv hluav taws xob, cov transformers feem ntau raug teeb tsa sib cais raws li cov pawg thauj khoom sib txawv thaum lub sijhawm teeb tsa lub kaw lus.

Cov transformers chaw khaws ntaub ntawv tshwj xeeb yuav tsum muaj cov yam ntxwv hauv qab no:

Cov Kev Cai Txhim Kho Siab: Chav kawm thauj khoom (qib) hauv cov chaw khaws ntaub ntawv feem ntau yog siab dua Qib 1, xav tau kev ntseeg siab rau kev muab hluav taws xob siab heev.

Cov Kev Cai Siv Hluav Taws Xob Zoo: Yuav tsum ua tau raws li lossis tshaj cov qauv siv hluav taws xob Qib 1.

Muaj Peev Xwm Ntau Dhau: Muaj peev xwm tswj tau qhov nce ntawm qhov hnyav sai sai.

Cov Kev Cai Siab Rau Kev Nyab Xeeb Hluav Taws: Xyuas kom meej tias lub chaw khaws ntaub ntawv ua haujlwm zoo.

2. Cov Yam Tseem Ceeb ntawm Kev Xaiv

2.1 Lub Peev Xwm Thauj Khoom thiab Tus Nqi Thauj Khoom

Kev xaiv lub transformer uas muaj peev xwm thauj khoom txaus yog qhov tseem ceeb heev vim tias qhov thauj khoom ntawm cov chaw khaws ntaub ntawv loj feem ntau nce ntxiv nrog kev txhim kho lag luam.

Qhov siab tshaj plaws ntawm kev thauj khoom (qhov tseeb ntawm kev thauj khoom / lub peev xwm ntsuas) rau lub transformer yog 70% -85%, uas yog qhov kev lag luam lees paub "kim kub." Qhov siab tshaj plaws ntawm kev thauj khoom hauv qab 70% ua rau lub transformer khiav hauv qab kev thauj khoom me me rau lub sijhawm ntev, nrog rau kev poob tsis muaj kev thauj khoom suav nrog qhov feem pua ​​​​​​ntau dhau. Ntawm qhov tod tes, qhov siab tshaj plaws ntawm kev thauj khoom siab tshaj 85% thawb lub transformer ze rau qhov kev thauj khoom tag nrho, ua rau lub kauj cua sov thiab ua rau muaj kev pheej hmoo ntawm kev ua tsis tiav.

2.2 Kev Ua Haujlwm Zoo thiab Kev Siv Hluav Taws Xob

Feem ntau cov chaw khaws ntaub ntawv loj yuav tsum tau ua haujlwm ntev, yog li ntawd, kev siv hluav taws xob ntawm lub transformer thiab kev siv hluav taws xob yog cov yam tseem ceeb uas yuav tsum xav txog. Cov transformers ua haujlwm tau zoo tuaj yeem txo kev siv hluav taws xob thiab txhim kho kev siv hluav taws xob, txuag cov nqi rau kev ua haujlwm ntawm chaw khaws ntaub ntawv.

Thaum xaiv lub transformer, nws yog ib qho tseem ceeb uas yuav tsum sib piv tsis yog tus nqi yuav khoom xwb tab sis kuj yog "kev poob tsis muaj load + kev poob load." Cov kev poob no yog cov neeg tua cov nqi hluav taws xob uas tsis pom thiab, thaum kawg, tej zaum yuav ntau dua qhov sib txawv ntawm tus nqi pib.

2.3 Kev Ruaj Ntseg thiab Kev Ntseeg Siab

Kev ruaj khov yog qhov tseem ceeb heev thaum lub sijhawm ua haujlwm ntawm lub chaw khaws ntaub ntawv. Kev xaiv lub transformer ruaj khov heev tuaj yeem lav qhov ua haujlwm ib txwm ntawm lub chaw khaws ntaub ntawv, zam kev poob cov ntaub ntawv lossis lwm yam teeb meem los ntawm cov teeb meem voltage.

Kev ntseeg tau yog ib qho ntawm cov qauv tseem ceeb rau kev ntsuas qhov zoo ntawm cov khoom siv. Lub transformer txhim khu kev qha tuaj yeem zam kev cuam tshuam cov ntaub ntawv thiab kev poob los ntawm kev ua tsis tiav ntawm cov khoom siv. Kev ua haujlwm tas mus li ntawm lub chaw khaws ntaub ntawv yog qhov tseem ceeb rau cov tuam txhab, yog li kev xaiv cov transformers uas muaj kev ntseeg siab thiab ruaj khov yog qhov tseem ceeb.

2.4 Kev Ruaj Ntseg Voltage thiab Harmonic Suppression

Cov transformers yuav tsum muaj qhov ruaj khov ntawm qhov hluav taws xob siab kom ntseeg tau tias cov khoom siv hauv chaw khaws ntaub ntawv tuaj yeem ua haujlwm tau ruaj khov thiab zam kev puas tsuaj los ntawm kev hloov pauv ntawm qhov hluav taws xob. Rau cov chaw khaws ntaub ntawv, cov khoom siv xws li cov servers thiab UPS yog qhov rhiab heev rau harmonics (harmonics ntau dhau tuaj yeem ua rau cov khoom siv tsis ua haujlwm). Nws yog qhov tsim nyog los xaiv cov transformers nrog qhov qis harmonic distortion rate (≤3%) thiab harmonic suppression function.

2.5 Kev Ua Haujlwm Kub Kub

Vim tias cov khoom siv hauv cov chaw khaws ntaub ntawv loj tsim cov cua sov ntau thaum lub sijhawm ua haujlwm, cov transformers yuav tsum muaj kev ua haujlwm zoo heev los tiv thaiv kev ua tsis tiav los ntawm kev kub dhau. Kev ua kom sov rau cov transformers chaw khaws ntaub ntawv feem ntau siv txoj kev AN / AF, piv txwv li, txias ntuj ntxiv los ntawm kev yuam cua txias.

2.6 Kev Tiv Thaiv Ib Puag Ncig thiab Kev Nyab Xeeb

Cov chaw khaws ntaub ntawv niaj hnub no tab tom tsom mus rau kev tiv thaiv ib puag ncig thiab kev ua haujlwm nyab xeeb. Cov khoom siv rwb thaiv tsev roj hmab silicone ua haujlwm siab muaj cov yam ntxwv kub hnyiab V0 qib - lawv tsis kub hnyiab thiab tsis tsim cov pa lom - ua rau lawv tsim nyog rau cov kev xav tau kev nyab xeeb hluav taws ntawm cov chaw khaws ntaub ntawv. Ntxiv mus, cov khoom tseem ceeb ntawm cov khoom siv rwb thaiv tsev roj hmab silicone yog dimethylsiloxane thiab cov khoom siv thermally conductive, uas tsis muaj tshuaj lom. Lawv tsis muaj teeb meem rau tib neeg kev noj qab haus huv thaum lub sijhawm tsim khoom, kev ua haujlwm, thiab cov txheej txheem rov ua dua ntawm cov xov hluav taws xob transformer, tsis muaj cov pa roj tawm lossis cov kua pov tseg, thiab cov ntaub ntawv tuaj yeem rov ua dua thaum kawg ntawm lawv lub neej voj voog.
