5 MVA Traction Fais Fab Transformer-22/6.6 kV|South Africa 2025

01 General

1.1 Project Description

5 MVA traction transformer tau xa mus rau Canada hauv 2025. Lub zog ntsuas ntawm lub transformer yog 5000 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 22 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 6.6 kV, lawv tsim ib pawg vector ntawm Dyn11.

Hauv kev teb rau cov xwm txheej xob laim (12 hauv av flashes ib square km ib xyoos twg) thiab cov tshuaj ntsev hnyav thiab muaj kuab paug hauv South Africa, nws tsim tau txiav txim siab txog kev tiv thaiv kev tiv thaiv thiab kev tiv thaiv corrosion. Cov roj tank yog ua los ntawm cov hlau phaj nrog lub thickness ntawm ntau dua los yog sib npaug li 6 hli, thiab cov phaj hauv qab thickness ncav cuag 16 hli. Lub thickness ntawm txheej nyob rau hauv cov cheeb tsam uas muaj kuab heev yog 125 microns. Tsis tas li ntawd, cov roj tank thiab lub tshuab hluav taws xob tau txais kev sib tw vuam tsim los xyuas kom muaj lub zog thiab kev sib khi ua haujlwm.

Nyob rau hauv cov nqe lus ntawm lub ntsiab functional configuration, lub transformer yog nruab nrog ib tug NLTC tsis muaj -load kais-hloov, txhawb ib tug voltage kev cai ntau yam ntawm ± 2 × 2.5% thiab featuring padlockable functionality los xyuas kom meej qhov tseeb thiab kev ruaj ntseg voltage tswj. Qhov qis-voltage winding tuaj yeem tiv taus tag nrho qhov hluav taws xob sib xyaw ua ke ntawm txog 27%, hloov mus rau qhov chaw sib txuas hluav taws xob. Lub winding muaj lub zog txhua yam txaus los tiv thaiv qhov txhaum tam sim no, thiab qhov chaw nyob muaj qhov kev tshem tawm hauv av ntawm 3500mm, ua raws li cov qauv kev ua haujlwm siab -voltage. Lub caij no, cov cuab yeej tau nruab nrog ntau yam kev tiv thaiv, suav nrog ib qho - ntab roj relay (nrog lub tswb thiab cov neeg mus ncig ua si), cov khoom siv hluav taws xob ntau dhau (nrog rau qhov ntsuas kub ntawm qhov ntsuas kub, qhov ntsuas kub mus rau qhov kub ntawm 115 degree), dial - hom roj qhov ntsuas qhov ntsuas kub (kho qhov kev sib cuag teeb tsa ntawm 90 degree), thiab lub sijhawm ua haujlwm tsis zoo ntawm lub valve. sai sai.

02 Kev tsim khoom

2.1 Core

Cov tub ntxhais transformer yog lub hauv paus sib nqus Circuit Court ntawm lub traction transformer. Tsim los ntawm siab -permeability silicon steel laminations, nws ua tau zoo raws alternating sib nqus flux nrog tsawg zog poob. Qhov no yog qhov tseem ceeb rau kev txhim kho lub zog hloov pauv thiab kev ua haujlwm ruaj khov raws li qhov xav tau ntawm kev thauj mus los ntawm kev tsheb ciav hlau.

 

2.2 Cua txias

Lub nruam disc winding yog ib qho tseem ceeb coil hom hauv traction transformers. Nws yog tsim los ntawm winding rectangular conductors nyob rau hauv ib tug series ntawm radial discs tsis muaj soldered pob qij txha ntawm lem. Cov txheej txheem kho tshuab muaj zog no muab qhov tshwj xeeb luv luv - lub zog hluav taws xob thiab cov cua sov kom zoo, uas yog qhov tseem ceeb rau kev ua haujlwm txhim khu kev qha nyob rau hauv qhov kev hloov pauv tsis tu ncua.

 

2.3 Tank

Lub tank ua hauj lwm raws li kev tiv thaiv enclosure thiab ib qho tseem ceeb txias system rau lub traction transformer. Nws yog mechanically robust tiv thaiv kev vibrations thiab cuam tshuam, thaum nws tsim optimizes tshav kub dissipation los xyuas kom meej cov tub ntxhais thiab windings ua hauj lwm nyob rau hauv kev nyab xeeb kub, guaranteeing kev ntseeg tau raws li xav tau kev pab cuam.

 

2.4 Lub Rooj Sib Tham Kawg

Kev sib dhos zaum kawg yog cov txheej txheem tseem ceeb ntawm kev sib koom ua ke ntawm cov tub ntxhais, windings, thiab lub tank rau hauv qhov ua tiav thiab txhim khu kev qha traction transformer. Nws ua kom muaj kev sib raug zoo ntawm cov neeg kho tshuab, kev ncaj ncees, thiab cov roj- nruj sealing, uas ua rau lub zog muaj peev xwm ntawm kev xa cov kev ua tau zoo raws li qhov xav tau ntawm kev ua haujlwm railway.

 

 

03 Kev Xeem

Lub tshuab hluav taws xob traction no tau dhau los ua cov txheej txheem niaj hnub, hom thiab kev sim tshwj xeeb kom paub tseeb tias nws cov hluav taws xob ncaj ncees, kev ua haujlwm tau zoo, thiab kev ntseeg siab ntev ntev. Cov txheej txheem kev sim nruj, suav nrog lub zog dielectric, qhov poob, qhov sib piv, rwb thaiv tsev, thiab roj- hauv - roj tshuaj ntsuam xyuas, lees paub lub tsev tag nrho ua raws li kev ua tau zoo thiab nws qhov kev npaj rau kev thov kev pabcuam kev tsheb ciav hlau.

04 Packing thiab Shipping

4.1 Ntim

Lub ntim ntawm lub traction transformer yog engineered rau siab tshaj plaws kev tiv thaiv thaum lub sij hawm thauj mus los thiab cia.
