6 MVA RAILWAY transformers-22 / 1.22 kv|South Africa 2023

01 dav dav

1.1 project keeb kwm yav dhau

Qhov no 6Mva Traction Transformer raug xa tawm mus rau South Africa nyob rau lub Yim Hli 2024. Tus thawj voltage yog 22 kV, qhov thib ob voltage yog 2 * 1.22 • 1.22 KV, lub transformer yog tsis muaj kev sib tsoo yog ± 2 * ntawm lub xub ntiag, cua txias yog onan.

Lub transformer yog tsim los txo qhov cuam tshuam ntawm kev cuam tshuam kev cuam tshuam nrog kev cuam tshuam. Thaum lub transformer yog tag nrho cov kev thauj khoom tsis tu ncua, ntsuas kub tsis tshaj 70℃c, thiab tsis pub tshaj 100℃c hauv qab 2 zaug thauj mus los hauv 30 feeb. Lub transformer yog nruab nrog overload thermal relay los tiv thaiv cov overloader nrog ambient kub raug them thiab hloov chaw. Lub transformer yog nruab nrog lub radeatorable radiator. Cov Upsiator Adopts ib qho kub tshwj xeeb tshaj plaws- dip galvanizing txheej txheem thiab cov khoom siv hluav taws xob yog pleev xim thiab insulated. Lub transformer tuaj yeem tiv taus 3.5 zaug lub nra.

02 kev tsim khoom

2.1 Tub ntxhais

Lub tsev:

● Muaj peb ob txhais ceg ntsug thiab sab saud thiab qis dua, sib nqus cov sib nqus Circuit Court.

Txhua tus ceg nqa ib theem winding, kom ntseeg tau peb lub -} theem sib nqus kev.

Khoom:

Ua los ntawm high -} permeability Silicon Lamations coated nrog insulating vanish los txo cov vardy tam sim no thiab hysteresis poob.

Ua yeeb yam:

Disasting flux faib yog qhov tsis zoo, nrog minimal toluxage flux thiab high efficiency.

Cov hau kev hloov kho feem ntau suav nrog cov roj cua txias lossis cua txias, nrog cov qauv ruaj khov kho thiab zoo heev kev co ua haujlwm.

2.2 cua

Kev Txuas: Y / D11y0y0N (Tsawg Voltage Thib Peb Muaj Peev Xwm 150Kva)

High Voltage Winding: Kev sib txuas hnub qub

Tsawg cov hluav taws xob tsis tshua muaj cua: Lub kaum sab sib txuas

Tsis tshua muaj hluavtaws theem nrab Winding: kev sib txuas hnub qub

Tsawg - voltage tertiae winding: qhov thib ob transformer muab lub zog thib peb los yog winderary winding los yog winding thib peb tuaj yeem ua nyias. Qhov thib peb winding yuav tsum muaj lub tes tsho sib txawv, uas tuaj yeem muab lub zog rau cov kev hloov pauv. Tus tso kev hloov pauv yog 150kva.

Qhov ntsuas kub nce:

Ntawm nruam puv thauj khoom, ntsuas kub nce ntawm lub transformer windeding yuav tsum tsis pub tshaj 65℃c tom qab thermal equilibrium thiab ruaj khov kub

1 feeb 3 zaug lub nra tsis pub tshaj 70 degree

10 vib nas this 3.5 zaug lub nra tsis tshaj 70℃c

30 feeb 2 zaug lub nra tsis tshaj 100℃c

Tsawg dua voltage thib peb winding voltage 1.22kv, muaj peev xwm, nrog nruab nrab

Lub High Voltage Winding Adjts Cincts Disc Winding thiab Lub Voltage Tsawg Winding Cug Txiaj Ntsig Clearing

Txhua tus windings yog tag nrho insulated

Lub transformer yog siv nyob rau thaj tsam ntawm hnyav xob hnyav, thiab cov xob laim tsim tawm yog ntsia nruab nrab ntawm lub siab lub tsheb npav thiab kev hloov pauv

Transformer windings muaj cov tshuab muaj zog txaus kom tawm tsam cov neeg txhaum tau zoo

2.3 Tank

Lub tank yog ua los ntawm cov hlau phaj ntau dua lossis sib npaug rau 6 hli

Tank hauv qab phaj tuab 16mm

Transformer Tank Grey, Roj Taub Hau Dawb, Xim Thickness ntawm tsawg kawg 125 microns

Ntawm lub ntsiab roj tsim hluav taws xob, muaj cov kais dej loj rau ntawm cov hauv ncoo thiab ib sab yog qhov chaw nyob ntawm qhov chaw siab (yog tias tsim nyog, sab nrauv tau ua ke nrog lub roj ntws qis) tus kais dej muaj 50 hli sab hauv xov

2.4 Lub Rooj Sib Tham Zaum Kawg

03 kuaj

1. Kev ntsuas ntawm cov tshuaj uas yaj nyob rau hauv dielectric kua los ntawm txhua cov roj nyias nyias tsuas yog cov roj hloov pauv

2. Kev ntsuas ntawm voltage piv thiab tshawb xyuas theem kev sib tsoo

3. Kev ntsuas ntawm winding kam Roj Temp: 33.0 Degree cov neeg muaj kuab: 63% chav: ω

4. Tshawb xyuas cov tub ntxhais thiab cov ncej rwb thaiv tsev rau cov roj uas raus nrog cov tseem ceeb lossis cov ncej rwb thaiv tsev roj Temp: 33.0 Degree cov neeg muaj kuab: 63%
