Yuav Ua Li Cas Kuv Xaiv 1500 kVA Transformer?

Yuav Ua Li Cas Kuv Xaiv 1500 kVA Transformer?

Lub 1500 kVA transformer yog ib chav faib loj, feem ntau yog siv rau kauj ruam 10 kV lossis 11 kV mus rau 400/230 V rau cov nroj tsuag kev lag luam, cov ntaub ntawv chaw, cov chaw yuav khoom thiab cov chaw siv hluav taws xob me me. Kev xaiv nws kom raug txhais tau hais tias sib piv cov kev ntsuas hluav taws xob, kev ua haujlwm tsis zoo thiab kev tsim kho tshuab rau qhov kev thauj khoom tiag tiag, yog li cov lus qhia no ua raws cov kauj ruam - los ntawm - cov txheej txheem xaiv raws li IEC 60076 thiab GB 20052 cov chav kawm kev siv hluav taws xob.

Kauj ruam 1: Txhais qhov Load Profile

Xam qhov kev thov siab tshaj plaws hauv kVA los ntawm cov khoom siv sib txuas, muaj ntau haiv neeg thiab kev loj hlob uas xav tau. Lub tshuab hluav taws xob yuav tsum nquag khiav ntawm 60-80% ntawm daim ntawv teev npe kom tso cai rau overloads thiab ua kom poob tau txais. Yog hais tias lub load yog heev cyclic los yog muaj harmonic cov ntsiab lus, xyuas cov K-factor los yog harmonic ntsuam xyuas ua ntej kho lub peev xwm.

Kauj Ruam 2: Match Voltage thiab zaus

Paub meej tias thawj qhov hluav taws xob (piv txwv li 10 kV, 11 kV, 20 kV lossis 33 kV), qhov hluav taws xob theem nrab (400/230 V lossis 415 V peb-theem, lossis 480 V rau 60 Hz kev lag luam), zaus (50 lossis 60 Hz) feem ntau yog Dyn11 pawg neeg faib khoom Lub impedance voltage, feem ntau 4-6% ntawm qhov kev ntsuam xyuas no, yuav tsum sib haum rau qib kev ua txhaum ntawm lub switchgear.

Kauj Ruam 3: Sib piv qhov poob thiab qhov ua tau zoo

Tsis muaj- load poob yog tas mus li thiab dominates tus nqi txhua xyoo rau cov khoom thauj me me; load poob dominates thaum lub transformer khiav ze qhov ntsuas. Thov qhov tsis muaj-load thiab load poob qhov tseem ceeb los ntawm daim ntawv tshaj tawm kev xeem niaj hnub thiab sib piv tag nrho cov nqi ntawm cov tswv cuab tshaj 10-20 xyoo, tsis yog tus nqi yuav khoom xwb. Cov chav kawm siv hluav taws xob xws li GB 20052 lossis EU Eco-tsim Tier 2 teeb tsa qhov siab tshaj plaws uas coj kev xaiv.

Kauj ruam 4: Xaiv Txias thiab Enclosure

ONAN roj- cov chav nyob rau hauv dej yog cov qauv kev lag luam rau cov chav sab nraum zoov lossis cov chav tshwj xeeb. Yog tias qhov chaw nruj nyob hauv tsev, qhov qhuav -hom (cam khwb cia resin) transformer zam cov roj ntim thiab hluav taws kub tab sis raug nqi ntau dua. Txheeb xyuas qhov kub thiab qhov siab: siab dua 40 degC lossis 1000 m, qhov cuam tshuam tsis zoo siv thiab yuav xav tau ib chav loj dua.

Kauj ruam 5: Txheeb xyuas Kais Changer thiab Accessories

Qhov tawm -Circuit kais changer nrog +/-2 x 2.5% lossis +/-5% npog feem ntau cov kab sib txawv. Qhia tshwj xeeb winding ntsuas kub, roj ntsuas kub, kev tiv thaiv Buchholz thiab siab nyem rau cov roj units, thiab tsim nyog tiv thaiv relays thiab CTs rau thawj sab.

Kauj Ruam 6: Tshawb xyuas kev teeb tsa thiab Kev Tshawb Fawb

Foundation, clearances thiab qhov cua raws li tus neeg tsim khoom kos duab thiab cov lej hauv zos.

Cov kev ntsuam xyuas niaj hnub: winding resistance, voltage ratio, vector group, tsis muaj-load poob thiab tam sim no, load poob thiab impedance, dielectric test, thiab ntsuas kub (hom test).

Roj zoo: tawg voltage thiab noo noo cov ntsiab lus raws li IEC 60296 ua ntej energizing.

Spare xeem: gaskets, bushings, indicators, As thiab conservator breather cartridge.

Feem ntau yuam kev

Sizing tsuas yog ntawm nameplate kVA thaum ignoring voltage regulation thiab pib tam sim no ntawm loj motors.

Tsis quav ntsej txog kev sib haum xeeb, uas ua rau muaj kev poob qis hauv kev sib tw thiab ua kom lub neej ua haujlwm luv.

Xaiv ib chav tsev pheej yig dua nrog kev poob siab dua, uas tuaj yeem raug nqi ntau dua li ntawm peb mus rau tsib xyoos.

Tsis nco qab pawg vector, ua rau kev ua haujlwm sib luag lossis theem - hloov teeb meem.

FAQ

Yuav ua li cas thauj khoom 1500 kVA transformer?

Ntawm 400 V peb-theem, 1500 kVA sib raug rau kwv yees li 2160 A kab tam sim no. Lub peev xwm siv tau yog nyob ntawm qhov xwm txheej puag ncig, hom cua txias thiab qhov ua tau poob qis.

Dab tsi yog qhov impedance voltage ntawm 1500 kVA transformer?

Feem ntau 4-6% rau chav faib khoom; tus nqi tiag tiag yuav tsum phim qhov chaw tiv thaiv thiab qib kev ua txhaum ntawm lub network.

Roj-immersed lossis qhuav- hom ntawm 1500 kVA?

Roj-immersed yog pheej yig dua thiab muaj tus cwj pwm zoo dua; qhuav - hom suits sab hauv tsev, hluav taws kub - rhiab heev los yog siab - nce kev teeb tsa qhov chaw muaj roj muaj teeb meem.

Yuav ua li cas thiaj paub qhov ua tau zoo ntawm transformer?

Siv daim ntawv tshaj tawm kev xeem niaj hnub: kev ua haujlwm ntawm 50% thiab 100% load tuaj yeem xam los ntawm tsis muaj-load poob, load poob thiab lub zog ua haujlwm, thiab piv nrog cov chav kawm siv hluav taws xob.

1500 kVA transformer puas tuaj yeem ua haujlwm sib luag?

Yog, muab cov vector pawg, qhov sib piv voltage, impedance thiab kais txoj haujlwm tau sib xws; sab laj cov chaw tsim khoom rau cov ntaub ntawv ua haujlwm sib luag.
