Tsim cov khoom siv hluav taws xob rau lub tsev siab - nce siab yog ib qho kev ua haujlwm uas muaj kev ntseeg siab, kev nyab xeeb, thiab qhov chaw ua kom zoo dua qub tsis yog - sib tham. Kev xaiv thiab raug txuam nrog lub ntsiab fais fab transformer yog qhov kev txiav txim siab hauv paus.
Ib800kVA 20kV qhuav{2}}hom transformerfeem ntau ua haujlwm zoo tshaj plaws hauv thawj lossis theem nrab faib chav tsev rau nruab nrab - mus rau - cov yees loj, ntsuas qhov muaj peev xwm loj nrog qhov zoo ntawm qhov nruab nrab niaj hnub no -voltage mov.
Kev sib raug zoo muaj ntau tshaj li kev sib txuas ntawm cables; nws yuav tsum muaj kev soj ntsuam holistic ntawm lub tsev load profile, cov khoom siv hluav taws xob faib hluav taws xob, thiab cov kev sib tw tshwj xeeb ntawm cov qauv ntsug.
Phau ntawv qhia no qhia txog cov kev xav txog engineering tseem ceeb rau kev haum zoo.
Peb yog leej twg: Koj tus kws tshaj lij hauv kev tsim hluav taws xob faib hluav taws xob
GNEE yog ib lub chaw tsim khoom lag luam uas muaj kev paub dhau los hauv kev muab qhuav- hom transformer kev daws teeb meem rau kev lag luam thiab siab - nce kev tsim kho cov haujlwm. Peb nkag siab cov cai nruj, qhov chaw txwv, thiab kev ntseeg siab xav tau ntawm cov tsev niaj hnub. Peb800kVA 20kV qhuav{2}}hom transformersyog tsim los ua ke los sib txuas ua ke rau hauv cov txheej txheem kev tswj hwm lub tsev, muab lub zog zoo, nyob ntsiag to, thiab muaj txiaj ntsig zoo rau koj lub tsev skyscraper lossis ntau- siv ntauwd.
Ua Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Hluav Taws Xob rau Lub Tsev
Thawj kauj ruam tseem ceeb tshaj plaws yog kev suav cov load kom raug. Cov800kVA uakev ntsuam xyuas yuav tsum ua kom haum rau lub tsev qhov kev thov tiag tiag. Qhov no suav nrog kev txheeb xyuas qhov txuas txuas ntawm txhua lub tshuab:
- HVAC Systems:Chillers, cua txias yees, cua tuav chav (feem ntau yog qhov loj tshaj plaws load).
- Kev thauj mus los ntsug:Lub tsev txhab nyiaj of elevator thiab escalators, xav txog lawv cov cyclic thiab siab -inrush xwm.
- General Power & Teeb pom kev zoo:Rau chaw ua haujlwm, chav nyob, lossis tsev so hauv tsev.
- Critical Systems:Cov chaw zov me nyuam cov ntaub ntawv, teeb pom kev zoo thaum muaj xwm ceev, cov twj tua hluav taws, thiab cov kab ke kev nyab xeeb ntawm lub neej.
Siv cov qauv kev lees paub (xws li NEC Tshooj 220 lossis IEC 60364) thiab siv qhov tseebyam muaj ntau haiv neeg, raws li tsis yog txhua yam khoom siv ua haujlwm ntawm lub ncov ib txhij. Lub hom phiaj yog qhov loj ntawm lub transformer kom nws ua haujlwm tau zoo (feem ntau ntawm 50-85% load) nyob rau hauv ib txwm muaj, nrog lub peev xwm rau yav tom ntej tus neeg xauj tsev haum-outs lossis ntxiv. Ib chav tsev undersized yuav overheat; ib tug oversized yuav ua hauj lwm inefficient ntawm tsawg load.
Kev koom ua ke ntawm 20kV System thiab Transformer rau hauv Lub Tsev Architecture
Siv a20kV nruab nrab-voltage faibsystem nyob rau hauv lub siab - nce lub tsev yog lub tswv yim tseem ceeb rau efficiency thiab chaw txuag. Nws tso cai rau lub hwj chim faib vertically nrog qis tam sim no, txo cov cable loj thiab lub zog poob.
- Qhov chaw:Lub transformer feem ntau yog nyob rau hauv ib tug tshwj xeebchav hluav taws xob hauv qab daus los yog hauv pem teb technical. Chav tsev no yuav tsum muaj qhov cua txaus, hluav taws kub - ntsuas kev tsim kho, thiab kev nkag mus tau zoo.
- Kev sib txuas lus:Lub tshuab hluav taws xob tuaj yeem tau txais 20kV ncaj qha los ntawm kev siv hluav taws xob nkag thiab nqis mus rau 400V / 230V rau hauv zos qis-voltage faib. Xwb, nyob rau hauv cov complexes loj, nws yuav nqis los 20kV mus rau 11kV los yog 6.6kV rau nruab nrab ntsug risers, nrog me transformers nyob rau hauv pem teb.
- Qhuav -Hom Advantage:Covroj-dawb, hluav taws kub- tsim kev nyab xeebntawm qhuav-hom transformer yog yuav tsum tau rau kev teeb tsa sab hauv tsev hauv cov tsev nyob, ua raws li cov cai hluav taws xob nruj (xws li NFPA, IBC).
Rau lub hauv paus ntawm koj lub tsev lub zog system, tshawb xyuas peb ntau yam ntawmqhuav -hom faib transformers.
Qhia txog qhov tseem ceeb ntawm Transformer Performance thiab Safety Features
Thaum sib piv cov transformer, cov lus qhia tshwj xeeb no tseem ceeb heev rau kev siv siab -nce:
- Impedance (Uk%):Tus nqi ntawm 6-8% yog qhov ntau. Nws yuav tsum tau koom tes nrog cov khoom siv hluav taws xob thiab cov khoom siv tiv thaiv qis qis kom txwv tsis pub muaj kev cuam tshuam tam sim no thaum tswj kev tswj hwm qhov hluav taws xob zoo.
- Suab Level:Qhia meej alow- suab nrov tsim (< 65 dB(A)). Transformers in buildings must not cause audible disturbance to occupants in adjacent spaces.
- Kub nce thiab txias: Chav Kawm H (180 degree)rwb thaiv tsev nrog 80K lossis 100K kub nce kom ntseeg tau lub neej ntev. Huab cua Natural (AN) txias yog tus qauv, tab sis Air Forced (AF) muaj peev xwm muab peev xwm rov ua dua rau qhov siab tshaj plaws lossis siab dua ambient kub.
- Kev Tiv Thaiv & Saib Xyuas:Yuav tsum tau ua -inPt100 kub sensorstxuas nrog Lub Tsev Tswj Xyuas Txheej Txheem (BMS) rau kev saib xyuas kev kwv yees. Xyuas kom lub enclosure muaj siab txausIP ntsuam xyuas (piv txwv li, IP20 rau chav huv).
Kev sib koom tes nrog kev tiv thaiv, kev sib haum xeeb txo qis, thiab cov cai
Lub transformer tsis ua haujlwm hauv kev sib cais. Kev sib txuam kom zoo yuav tsum muaj kev sib koom ua ke - dav:
- Cov cuab yeej tiv thaiv:Thawj (20kV) sab yuav tsum muaj kev sib koom ua ke fuses lossis lub Circuit Court breaker. Qhov thib ob sab xav tau qhov tsim nyog ntsuas LV Circuit Court breaker.
- Harmonic Mitigation:Niaj hnub nimno cov tsev nrog dav LED teeb pom kev zoo thiab VFDs ntawm HVAC motors tsim harmonics. Qhia meej aK-rated transformer (piv txwv li, K-13)los yog ib tug nrog akev tsim kho harmonic mitigation tsimtiv thaiv overheating.
- Ua raws li:Tag nrho cov txheej txheem, suav nrog lub tshuab hloov pauv, yuav tsum ua raws li cov cai hauv zos, cov lej hluav taws xob (IEC / NEC), thiab cov kev cai siv hluav taws xob sib txuas.
GNEE txoj kev txhawb nqa engineering yog qhov tseem ceeb ntawm no. Peb muab cov ntaub ntawv tsim nyog rau koj cov kev tshawb fawb tiv thaiv thiab kev tsim qauv.
