Yuav Ua Li Cas Cov Neeg Yuav Tsum Qhia Txog Lub Chaw Haujlwm Tsis Muaj Kev Sib Txuas Hluav Taws Xob rau N + 1 lossis 2N? 

Cov neeg yuav khoom yuav tsum tau qhia a data center uninterruptible fais fab mov los ntawm qhov tseem ceeb ntawm kev thauj khoom hauv ob qho tib si kW thiab kVA, nws lub zog qhov tseem ceeb thiab txoj kev loj hlob, tom qab ntawd txhais seb cov qauv tsim nyog yog N, N + 1, lossis 2N. Runtime, roj teeb tej yam kev mob, txij nkawm bypass, generator kev sib koom tes, kev tiv thaiv txhaum, ib feem-load efficiency, xyuas, thiab FAT / SAT txais yuav tsum tau muab cais.

Data Center Uninterruptible Power Supply Architecture

Cov ntawv no tsis lav txog qib muaj nyob. Cov hom hom - roj teeb, bypasses, switchgear, tswj, txias, chav, thiab downstream tis - yuav tsum tau mapped ntawm ib kab ntawv.

Xam qhov Critical Load hauv kW thiab kVA

Tsim kom muaj lub sijhawm thauj khoom rau IT cov cuab yeej, network systems, cia, tswj, thiab txhua yam khoom siv lossis kev txhawb nqa uas UPS yuav tsum nqa. Cov ntaub ntawv:

• tam sim no kW thiab kVA;
• xav tau lub zog;
• pib lossis tus cwj pwm tsis zoo;
• npaj load los ntawm expansion theem;
• Cov khoom tsis tseem ceeb tsis suav nrog UPS;
• kev xav txawv txawv.

Siv kev loj hlob thiab tsim cov paj kom meej meej. Nkaum tag nrho cov nyiaj pub dawb hauv ib tus lej loj ua rau kev ua haujlwm tau zoo, lub sijhawm siv roj teeb, thiab kev rov ua dua nyuaj rau kev txheeb xyuas.

Txhais Redundancy rau hauv Module Quantities

Rau ib qho kev ua haujlwm modular, hais txog cov khoom thauj uas yuav tsum tau nyob twj ywm tom qab lub module tau hais tseg tsis muaj. A "250 kVA N + 1 system" yog qhov tsis meej tshwj tsis yog qhov ntsuas ntsuas ntsuas, ntsuas ntsuas ntsuas, tiv thaiv kev thauj khoom, thiab tso cai tshaj tawm.

Tus neeg yuav khoom sib piv a 25-250 kVA modular UPS nrog loj 100-180 kVA los yog 200-800 kVA platforms yuav tsum normalize lub tswv yim nyob ib ncig ntawm usable tiv thaiv muaj peev xwm, tsis tsuas yog lub txee ntaus nqi.

Txhais Runtime ntawm lub npe Load

"Peb caug-feeb thaub qab" yuav tsum txheeb xyuas cov load, roj teeb kawg voltage, kub, laus assumption, thiab seb UPS poob thiab auxiliaries koom nrog. Kuj tseem qhia:

• roj teeb chemistry thiab nyiam kev npaj;
• tsim lub neej lossis kev cia siab rau kev pabcuam raws li tau teev tseg;
• chav ntsuas kub thiab qhov cua;
• roj teeb saib xyuas;
• kev cais tawm thiab kev saib xyuas;
• recharge yuav tsum tau tom qab tso tawm;
• generator pib thiab stabilization sequence.

Yog tias lub tshuab hluav taws xob tau npaj rau kev txhawb nqa mus ntev, UPS tseem xav tau kev ywj pheej txaus rau kev tshawb nrhiav, pib, hloov pauv, thiab kev ntseeg siab pib ua tsis tiav.

Engineer Bypass thiab Maintenance

Qhia qhov yuav tsum tau muaj qhov zoo li qub bypass, kev saib xyuas sab hauv bypass, thiab sab nraud wraparound bypass kev npaj. Tus qauv tsim yuav tsum piav qhia tias cov kws tshaj lij tuaj yeem cais UPS lossis cov qauv li cas thaum lub sijhawm thauj khoom tseem nyob ntawm txoj kev pom zoo.

Paub meej tias bypass input qhov chaw, synchronization qhov rais, luv-circuit muaj peev xwm, tiv thaiv xaiv, interlocks, thiab hloov tej yam kev mob. Hauv 2N systems, xyuas kom muaj kev saib xyuas ntawm ib txoj hauv kev tsis cuam tshuam rau lwm tus.

Sib piv Efficiency ntawm Real Loading

Headline qhov ua tau zoo tshaj plaws yuav tshwm sim ntawm qhov chaw thauj khoom uas qhov chaw tsis tshua ncav cuag. Thov kev ua tau zoo thiab cov ntaub ntawv nkag-kev ua tau zoo ntawm cov ntsiab lus ua haujlwm xav tau, suav nrog kev rov ua dua qub. Piv txwv li, txhua sab ntawm 2N architecture yuav khiav ze ntawm ib nrab ntawm cov khoom hauv ib txwm muaj.

Nug cov neeg sib tw los txheeb xyuas:

• hloov dua siab tshiab thiab lwm yam kev khiav hauj lwm hom;
• kev ntsuas kev ua tau zoo;
• input power factor thiab harmonic kev ua tau zoo;
• cua sov tsis kam ntawm cov khoom uas cuam tshuam;
• auxiliary thiab roj teeb-them noj;
• tej yam kev mob uas ua rau hloov hom.

Qhia saib xyuas thiab kev koom ua ke

Sau cov kev sib cuag qhuav uas yuav tsum tau muaj, cov txheej txheem, kev sib txuas hauv network, kev sib koom ua haujlwm hauv tsev, lub tswb, cov ntawv teev xwm txheej, kev saib xyuas roj teeb, kev nkag mus rau tej thaj chaw deb, thiab cybersecurity tswj. Txheeb xyuas seb leej twg muab lub rooj vag, daim ntawv tso cai, cables, kev teeb tsa, thiab kev ntsuas taw tes rau-point.

Kev saib xyuas yuav tsum ua kom pom lub xeev rov ua dua: cov qauv muaj, qhov feem pua ​​ntawm cov khoom thauj, kev hla dhau, cov teeb meem roj teeb, lub tswb nrov, thiab kev sib txuas lus poob.

Tus neeg muag khoom yuav tsum hais txog qhov kev txiav txim yam tsawg kawg nkaus lossis qhov project hauv paus, kev hloov kho, cov qauv siv tau thiab cov ntaub ntawv pov thawj, ntim thiab xa khoom ib ntus, lub sijhawm ua haujlwm los ntawm qhov tseem ceeb, tsis suav nrog, thiab kev siv tau zoo. Sib piv cov lus pom zoo siv tib qhov tseem ceeb ntawm kev thauj khoom, redundancy architecture, runtime, roj teeb assumption, efficiency, txij nkawm bypass, expansion plan, ib puag ncig tej yam kev mob, thiab lifecycle-support Scope.

Cov lus nug nquag

Puas yog N + 1 ib txwm ntseeg tsawg dua 2N?

Architecture labels ib leeg tsis tuaj yeem teb qhov ntawd. Kev ntseeg tau nyob ntawm txoj kev ua tiav lub zog, kev pheej hmoo ntawm hom, kev saib xyuas, kev tsim qauv, thiab kev ua kom zoo.

Yuav tsum muaj peev xwm UPS tsuas yog teev nyob rau hauv kVA?

Tsis yog. Muab ob qho tib si kW thiab kVA, nrog rau cov khoom siv hluav taws xob thiab kev coj tus cwj pwm, vim tias ob qho kev txwv tuaj yeem tswj tau.

Lub sijhawm ua haujlwm roj teeb puas nyob tas li thaum hloov pauv?

Tsis yog. Lub sijhawm ua haujlwm sib txawv nrog cov khoom thauj, lub roj teeb, qhov kub thiab txias, qhov system poob, txwv kev tso tawm, thiab cov kev xav ntawm kev laus.

Vim li cas thiaj thov ib nrab-load efficiency?

Cov tshuab tsis siv neeg feem ntau ua haujlwm qis dua qhov ntsuas tag nrho. Kev ua tau zoo ntawm qhov chaw ua haujlwm tiag tiag tsav cov cua sov thiab lub zog siv ncaj qha ntau dua li qhov siab tshaj plaws.

Dab tsi yuav tsum tau kuaj xyuas FAT?

Qhov project specification yuav tsum txhais nws. Tej yam uas yuav muaj xws li configuration, tswb, interfaces, hloov tsheb, load teb, bypass cwj pwm, thiab cov ntaub ntawv ua ntej xa zaub mov.
