1000 kVA Roj-Immersed Transformer Buying Guide: Specifications, Nyhav thiab Xaiv

Dab tsi yog 1000 kVA Kev Ntsuas Kev Ua Haujlwm

A 1000 kVA roj-immersed transformer yog ib qho kev xaiv rau nruab nrab- loj faib: Hoobkas fais fab blocks, khw khw, tsev kho mob, cov ntaub ntawv-centre vaj tse thiab cov khoom siv hluav taws xob substation feeders. Hauv kev ua haujlwm -cov ntsiab lus fais fab, ntawm lub zog ntawm 0.8 nws xa tawm txog 800 kW tsis tu ncua, thiab ntawm 0.9 lub zog ntawm 900 kW. Qhov kev txiav txim siab yuav yog li ntawd pib nrog kev kawm txog kev thauj khoom uas tsim kom muaj qhov xav tau siab tshaj plaws hauv kW, lub zog muaj zog, cov ntsiab lus sib haum xeeb thiab kev loj hlob, vim tias cov no txiav txim siab seb 1000 kVA yog qhov kev ntsuas zoo lossis seb 800 kVA lossis 1250 kVA haum zoo dua.

Core Specifications los kho ua ntej nqe lus

Qhov hnyav thiab roj ntim sib txawv nrog cov chaw tsim khoom thiab cov lus qhia poob; cov txiaj ntsig saum toj no yog qhov sib txawv rau cov chav kawm ntsuas thiab yuav tsum tau lees paub tiv thaiv qhov kos duab kos duab ntawm chav tsev, tshwj xeeb tshaj yog qhov chaw thauj mus los lossis kev thauj khoom hauv pem teb raug txwv.

Losses thiab Efficiency: Tus Nqi Them Nqi Them Rov Qab

Losses hloov ncaj qha mus rau hauv tus nqi hluav taws xob. Ib chav tsev 1000 kVA uas tsis muaj -load poob ntawm 1.6 kW dissipates txog 14,000 kWh ib xyoos tsuas yog los ntawm kev ua kom muaj zog, thiab kev poob qis ntxiv ntxiv qhov sib npaug rau lub square ntawm cov khoom thauj khoom. Tshaj li 20-xyoo lub neej, qhov sib txawv ntawm 0.3 kW hauv qhov tsis muaj kev thauj khoom muaj nqis ntau txhiab daus las ntawm kev lag luam tariffs, yog li qhov tshwj xeeb yuav tsum tau lees paub qhov kev poob siab tshaj plaws thiab yuav tsum tau ntsuas qhov tseem ceeb hauv daim ntawv tshaj tawm kev xeem niaj hnub. Qhov ua tau zoo ntawm qhov ntsuas load tsuas yog cov khoom sib faib los ntawm cov zis ntxiv rau tag nrho cov kev poob, uas yog vim li cas qhov kev poob qis, tsis yog qhov feem pua ​​​​ntawm cov txiaj ntsig, yog cov lej sib cog lus.

Factory Testing: Yuav Ua Li Cas Hauv Cov Ntawv Qhia

Raws li IEC 60076-1, cov kev ntsuam xyuas niaj hnub ntawm txhua chav muaj xws li kev hloov pauv thiab vector pawg pov thawj, kev ntsuas cua tiv thaiv, tsis muaj -load poob thiab tam sim no, load poob thiab impedance voltage, thiab dielectric xeem (siv thiab induced voltage). Rau cov roj-immersed chav tsev, cov qauv roj yog kuaj rau lub zog dielectric tawg raws li IEC 60296. Tus neeg yuav khoom yuav tsum thov daim ntawv pov thawj ua tiav cov ntawv pov thawj ntawm cov chav tsev tshwj xeeb, tsis yog daim ntawv tshaj tawm cov qauv, thiab xyuas tias qhov ntsuas qhov poob yog nyob rau hauv qhov kev lees paub qhov tseem ceeb thiab kev zam.

Installation thiab Maintenance Points

Muab lub tsev tso rau ntawm lub hauv paus qib ntsuas rau qhov hnyav tag nrho; cia chav rau radiators thiab sab conservator.

Txheeb xyuas cov roj qib hauv cov neeg saib xyuas thiab cov silica-gel xim ntawm lub tshuab ua pa ua ntej muaj zog.

Txuas lub tank thiab nruab nrab rau lub ntiaj teb daim phiaj; tus ntoo khaub lig-section ua raws cov cai hauv zos thiab qib ua txhaum.

Khaws cov qhov cua kom huv si; ONAN cua txias nyob ntawm huab cua ntws ncig lub tank thiab radiators.

Ua piv txwv cov roj ib xyoos ib zaug rau kev ntsuas hluav taws xob thiab cov roj yaj (DGA), thiab ntau zaus tom qab dhau los ntawm - txhaum.

Ua haujlwm tus kais hloov pauv tsuas yog de-energized tshwj tsis yog nws yog ib qho ntawm -load design.

Cov lus qhia xaiv thiab qhov yuam kev ntau

Qhov feem ntau yuam kev hauv kev yuav ib chav tsev 1000 kVA yog: xaiv qhov ntsuas los ntawm kev sib txuas kVA yam tsis muaj qhov sib txawv, tsis quav ntsej txog lub hwj chim, sib piv tsuas yog tus nqi yuav khoom thaum qhov poob qhov sib txawv dominates lifecycle tus nqi, thiab lees txais ib daim ntawv ntsuam xyuas uas tsis muaj nyob rau hauv qhov kev teeb tsa. Ib qho kev qhia tshwj xeeb uas tau lees paub qhov kev poob, cov qauv kev siv, thiab chav tsev - daim ntawv pov thawj tshwj xeeb tshem tawm feem ntau ntawm kev pheej hmoo.

FAQ

Lub zog hluav taws xob ntau npaum li cas tuaj yeem muab 1000 kVA transformer?

Txog 800 kW ntawm 0.8 lub zog ua haujlwm, lossis 900 kW ntawm 0.9. Daim duab qhia tseeb nyob ntawm cov nroj tsuag fais fab thiab qhov kev lees paub ntawm qhov hloov pauv.

Cov roj ntim thiab qhov hnyav tag nrho yog dab tsi?

Rau chav kawm 1000 kVA, tag nrho qhov hnyav yog kwv yees li 2,500 txog 3,500 kg nrog rau cov roj, thiab cov roj ntim yog li 500 txog 700 litres, nyob ntawm seb lub tank thiab radiator tsim.

Vim li cas qhov tsis muaj -load poob tseem ceeb yog tias nws zoo li me me?

Vim nws khiav 24 teev nyob rau ib hnub rau tag nrho lub neej ntawm transformer. Txawm tias 1 kW ntawm tsis muaj-load poob yog li ntawm 8,760 kWh ib xyoos twg, uas tau sau rau hauv tus nqi tseem ceeb hauv lub neej.

Cov kev xeem twg yuav tsum xeem dhau ua ntej xa khoom xa tuaj?

Cov kev ntsuam xyuas niaj hnub ntawm IEC 60076-1: piv thiab vector pawg, winding tsis kam, tsis muaj load poob thiab tam sim no, load poob thiab impedance, thiab siv thiab induced voltage dielectric xeem, ntxiv rau cov roj dielectric xeem ib IEC 60296.

Ntev npaum li cas cov roj yuav tsum tau kuaj hauv kev pabcuam?

Txhua xyoo rau lub zog dielectric, thiab DGA txhua xyoo tom qab thawj xyoo; Kev ua piv txwv ntau zaus raug pom zoo tom qab lub sijhawm luv luv -circuit tshwm sim lossis thaum lub load tau siab heev.

Hauv cov ntsiab lus, kev yuav cov roj 1000 kVA-immersed transformer yog ib qho kev qhia tshwj xeeb thiab kev ua pov thawj: kho qhov ntsuas los ntawm kev tshawb fawb, qhia qhov kev lav phib xaub tawm tsam IEC 60076 series, tshawb xyuas chav tsev- daim ntawv pov thawj tshwj xeeb, thiab npaj cov kev teeb tsa thiab roj- tu vaj tu tsev - 0 xyoo ua haujlwm puv sijhawm.
