Traction Transformer: Energizing Yav Tom Ntej Mobility
01 General
1.1 Project Description
5 MVA traction transformer tau xa mus rau South Africa hauv 2025. Lub zog ntsuas ntawm lub transformer yog 5000 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 66 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 1.22 kV, lawv tsim ib pawg vector ntawm Y / d ± 15℃d11.
Cov qauv tsim los rau kev ua haujlwm ntev, tus qauv kev tsheb ciav hlau hloov pauv tau txais kev ua pa pub dawb - ua pa nrog silicone grain breather kom tswj tau cov roj zoo, thaum nws bolted tank npog txhim kho kev sib khi. Cov galvanized radiators tsis tsuas yog muab cov cua kub kom zoo xwb tab sis kuj muaj kev tiv thaiv corrosion zoo heev, ntxiv rau ONAN (Oil Natural Air Natural) txoj kev txias txias uas lav kev lag luam txhim khu kev qha nyob rau hauv tas li load. Ob lub siab-voltage thiab qis-voltage windings yog tsim los ntawm tooj liab, xa cov hluav taws xob zoo tshaj plaws, tsis tshua muaj hluav taws xob poob, thiab ntev- lub sijhawm ua haujlwm ruaj khov.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, lub transformer exhibits impressive efficiency - mus txog 99.37% ntawm 1.0 lub hwj chim yam thiab 99.22% ntawm 0.8 lub hwj chim yam (ntawm 75 degree)- nrog cov hlau tsis tshua muaj (6000 Watts) thiab tag nrho - load tooj liab poob (25400℃ntawm Watts), tag nrho cov poob ntawm Watts 31 400 w. Nws tag nrho -load impedance sawv ntawm 8.15% (reactance: 8.13%), thiab kev tswj qhov hluav taws xob yog optimized rau 0.51% (1.0 PF) thiab 5.3% (0.8 PF) ntawm 75 degree, kom ntseeg tau meej voltage tswj. Nrog winding kub nce txwv rau 50℃thiab sab saum toj roj kub nce mus rau 45 degree, lub transformer zoo mitigates thermal stress, ncua nws cov kev pab cuam lub neej thiab ua tau raws li cov kev cai nruj ntawm traction fais fab mov systems rau kev nyab xeeb, efficiency, thiab sib xws.

02 Kev tsim khoom
2.1 Roj Conservator
Cov roj conservator yog lub ntim ntim ntim txuas nrog lub tank loj, tsim kom haum rau lub ntuj nthuav dav thiab kev cog lus ntawm cov roj insulating vim qhov kub thiab txias thaum lub sijhawm ua haujlwm. Los ntawm kev tswj hwm cov roj tsis tu ncua thiab txo cov roj kom raug rau huab cua, nws zoo tiv thaiv oxidation thiab noo noo ingress. Qhov kev ua haujlwm tseem ceeb no ua kom lub sijhawm ntev - ruaj khov ntawm cov roj dielectric zog, tiv thaiv cov rwb thaiv tsev sab hauv, thiab ua kom muaj kev ntseeg tau zoo thiab kev pab cuam lub neej ntawm lub transformer.
2.2 Winding Temperature Indicator
Lub Winding Temperature Indicator (WTI) yog ib qho tseem ceeb saib xyuas cov cuab yeej rau lub tshuab hluav taws xob traction. Nws simulates qhov kub tshaj qhov kub tshaj plaws nyob rau hauv lub winding, uas yog siab tshaj qhov ntsuas saum toj kawg nkaus - roj kub. Siv lub teeb pom kev hauv cov roj thiab cov khoom cua sov sib txuam txuas ntawm lub raj capillary, WTI qhia meej txog qhov tseeb ntawm cov cua sov ntawm cov cua sov. Nws muab qhov tseem ceeb ntawm kev nyeem ntawv kub thiab feem ntau ua rau lub tswb nrov thiab, yog tias tsim nyog, cov lus txib mus txawv tebchaws los tiv thaiv kev puas tsuaj ntawm rwb thaiv tsev thiab xyuas kom lub transformer ua haujlwm tau zoo nyob rau hauv nws cov kev txwv thermal.
2.3 Huab cua
Lub tshuab ua pa, lossis noo noo absorber, yog ib qho tseem ceeb tiv thaiv ntaus ntawv rau lub traction transformer. Mounted ntawm lub conservator lub pa yeeb nkab, nws muaj ib tug nqi ntawm silica gel desiccant. Raws li lub transformer ua pa vim roj expansion thiab contraction, tag nrho cov cua tuaj yog kos los ntawm no breather. Lub silica gel nquag nqus dej noo los ntawm huab cua, tiv thaiv nws los ntawm kev nkag mus rau hauv cov roj conservator thiab paug cov roj insulating. Qhov kev ua haujlwm tseem ceeb no tiv thaiv lub tshuab hluav taws xob sab hauv hluav taws xob los ntawm kev degradation, kom ntseeg tau tias lub zog dielectric thiab ntev - lub sijhawm ua haujlwm kev ntseeg siab.
2.4 Terminal Thawv
Lub thawv davhlau ya nyob twg yog ib qho chaw ruaj ntseg uas txuas rau ntawm lub traction transformer lub tank, nyob rau sab nraud cov hluav taws xob sib txuas rau qhov siab -voltage thiab low-voltage windings. Nws muab kev tiv thaiv kev tiv thaiv qhov twg insulated bushings xaus, thiab cables los ntawm railway lub hwj chim system txuas nrog. Nws lub luag haujlwm tseem ceeb yog ua kom muaj kev nyab xeeb, txhim khu kev qha hluav taws xob sib txuas, tiv thaiv cov terminals los ntawm ib puag ncig yam xws li ya raws thiab plua plav, thiab muaj kev nyab xeeb tseem ceeb rau cov neeg ua haujlwm thaum lub sijhawm ua haujlwm thiab kev saib xyuas, yog li ua kom tag nrho cov hluav taws xob ruaj khov thiab kev nyab xeeb ntawm lub tshuab hloov pauv.
2.5 Kub-Dip Galvanized Radiator
Qhov kub-dip galvanized radiator yog cov tub ntxhais txias ntawm cov qauv tsheb ciav hlau hloov pauv. Nws muaj ib tug series ntawm finned panels los yog cov hlab uas muab ib tug loj deg cheeb tsam kom dissipate tshav kub los ntawm insulating roj rau hauv ib puag ncig huab cua. Qhov tseem ceeb feature yog nws kub -dip galvanized steel nto, uas muab tshwj xeeb corrosion kuj. Qhov kev tiv thaiv ruaj khov no yog qhov tseem ceeb rau kev ua kom ntev ntev - lub sij hawm cov qauv kev ncaj ncees thiab kev ua kom zoo tshaj plaws ntawm kev hloov hluav taws xob, tshwj xeeb tshaj yog thaum lub tshuab hluav taws xob ua haujlwm hauv qhov chaw hnyav lossis qhov chaw ntub dej, yog li lav qhov kev ua haujlwm ruaj khov thiab txhim khu kev qha.
2.6 Active Part Drying
Lub tshuab ziab khaub ncaws qhuav yog txheej txheem tsim khoom tseem ceeb rau lub traction transformer's core -thiab-coil assembly (active part). Nws suav nrog tshem tawm cov dej seem ntawm cov cellulose rwb thaiv tsev (daim ntawv thiab pressboard) thiab cov tub ntxhais laminations los ntawm kev tswj cua sov hauv qab lub tshuab nqus tsev siab. Cov txheej txheem nruj no ua kom cov rwb thaiv tsev ua tiav cov ntsiab lus tsis tshua muaj dej thiab ruaj khov, uas yog qhov tseem ceeb rau kev tsim kom muaj lub zog dielectric siab, tiv thaiv kev tawm ntawm ib nrab, thiab lav lub transformer ntev - lub sij hawm cia siab rau thiab kev ua hauj lwm lifespan raws li xav tau railway tej yam kev mob.
03 Kev Xeem
Tag Nrho -Wave Lightning Impulse Test yog ib qho nyuaj siab -voltage type test siv rau cov kab terminals ntawm traction transformer. Nws simulates xob laim hnyav los ntawm kev siv tus qauv 1.2/50 µs voltage impulse. Qhov kev sim no txheeb xyuas qhov kev ncaj ncees thiab lub zog ntawm lub ntsiab rwb thaiv tsev, tshwj xeeb tshaj yog cov windings thiab bushings, nyob rau hauv cov xwm txheej tsis ntev los no overvoltage. Kev xeem dhau qhov kev sim no yog qhov tseem ceeb los ua pov thawj tias lub tshuab hluav taws xob muaj peev xwm tiv taus tiag tiag - xob laim hauv ntiaj teb, ua kom muaj kev tiv thaiv txhim khu kev qha rau txoj kev tsheb ciav hlau hluav taws xob.
