22 MVA Fais Fais Fais Fais Distribution Transformer-132/11 kV|South Africa 2025

01 General

1.1 Project Description

20/22 MVA fais fab transformer raug xa mus rau Canada hauv 2025. Lub zog ntsuas ntawm lub transformer yog 20 kVA nrog ONAN txias thiab 22 MVA nrog ONAF txias. Qhov siab voltage yog 132 kV nrog ± 8 * 1.25% tapping ntau (NLTC), qhov tsawg voltage yog 11 kV, lawv tsim ib pawg vector ntawm YNyn0.

Engineered rau seamless kev koom ua ke rau hauv koj cov infrastructure uas twb muaj lawm, lub ntsiab feature ntawm chav tsev no yog nws muaj peev xwm rauua haujlwm sib npaug nrog rau ntawm - qhov chaw transformer uas twb muaj lawmntawm1 32kvqib. Qhov no ua kom muaj kev ntseeg tau zoo dua qub, kev ua haujlwm yooj yim, thiab muaj peev xwm ua kom tau raws li qhov xav tau loj zuj zus. Lub transformer yog nruab nrog asab -mounted ntawm -load tap changer (OLTC)rau superior voltage kev cai thiab tsawg zog cuam tshuam thaum hloov. Rau kev tiv thaiv tseem ceeb tiv thaiv voltage surges thiab transient overvoltages, nws los ua tiav nrogintegrated xob laim ntes (surge arresters).Ib qho tseem ceeb tsim nam yog lubunified conservator tanksystem, qhov twg lub ntsiab conservator thiab tus kais changer conservator tau ua ke rau hauv ib qho, integrated unit. Qhov kev tsim kho tau yooj yim no ua kom yooj yim txij nkawm, txo cov kav dej sab nraud, thiab txhim kho kev ntseeg tau tag nrho. Tsis tas li ntawd, txhawm rau txhawb kev ua haujlwm ntev - lub sijhawm ua haujlwm tau npaj thiab yooj yim ntawm kev saib xyuas, lub tshuab hloov pauv tau muab nrog556 kg ntawm reserved insulating rojraws li ib tug thaub qab.

Kev sib txuas cov cuab yeej pov thawj nrog cov qauv tsim, qhov 22MVA transformer no yog tsim los xa cov kev ua tau zoo tshwj xeeb, ua haujlwm ntev, thiab kev ua haujlwm yooj yim hauv qhov xav tau kev siv hluav taws xob.

02 Kev tsim khoom

2.1 Core

Cov tub ntxhais yog tsim los ntawm qib siab -qib txias-rolled grain- taw qhia silicon steel laminations. Nws nta peb -theem, peb-limb tsim nrog ntau- kauj ruam ntoo khaub lig-section thiab tag nrho cov pob qij txha, ua rau qis- tsis kam sib nqus txoj kev uas txo qis tsis muaj- thauj khoom poob thiab ua haujlwm nrov. Tag nrho cov tub ntxhais yog ruaj ntseg clamped thiab muaj ib qho kev txhim khu kev qha hauv av los tiv thaiv kev tawm thiab cua sov, ua kom muaj zog hluav taws xob hloov pauv tau zoo thiab ua haujlwm ntev - lub sijhawm ua haujlwm ruaj khov.

 

2.2 Cua txias

Qhov no 22MVA, 132/11kV fais fab transformer siv ib tug nruam disc winding tsim rau ob qho tib si nws high -voltage thiab low-voltage windings, tsim los ntawm ca tooj liab conductors raug mob nyob rau hauv ib tug series ntawm contiguous discs raws li axial ntev ntawm cov tub ntxhais. Qhov kev teeb tsa muaj zog no muab cov tshuab ua kom muaj zog los tiv thaiv luv luv - Circuit Court quab yuam, cov khoom siv hluav taws xob zoo tshaj plaws, thiab kev ntseeg tau zoo dua, ua rau nws yog qhov kev xaiv dav dav rau transformers ntawm qhov ntsuas no.

 

2.3 Tank

Lub tank rau qhov transformer no yog tsim los ntawm siab- zoo steel phaj, tsim siv CNC txiav thiab txias- dabtsi yog khoov cov txheej txheem. Nws cov seams tseem ceeb yog txuas ntxiv txuas nrog automated submerged arc lossis CO₂ gas-shielded vuam los xyuas kom meej cov qauv kev ncaj ncees thiab lub foob hermetic. Cov corrugated panels yog stamped rau hauv cov duab, kev ntxhov siab-tuag, thiab tom qab ntawd welded rau lub cev tseem ceeb los tsim kom muaj kev nthuav dav. Tag nrho cov qauv raug txhaj tshuaj blasting thiab ua tiav nrog ntau txheej ntawm cov tshuaj tiv thaiv - cov xim pleev xim ua ntej thaum kawg tau ua nruj me ntsis rau kev xau thiab lub zog ntawm lub tshuab nqus tsev ntsuas.

 

2.4 Kev sib dhos zaum kawg

Qhov kawg sib dhos ntawm no 22MVA transformer pib nrog ua tib zoo txo ​​qis ua ntej -qhuav thiab insulated core- coil los ua ke rau hauv lub tank fabricated. Tag nrho cov khoom tseem ceeb-xws li bushings, ntawm -load kais-hloov, cua txias radiators, conservator, thiab saib xyuas cov cuab yeej- yog li txheej txheem ntsia thiab ua raws. Lub kaw lus raug tshem tawm mus rau lub tshuab nqus tsev siab ua ntej tau ntim cov roj purified insulating kom paub meej tias ua tiav impregnation thiab dielectric kev ntseeg. Thaum kawg, chav sib sau ua ke tau ua tiav cov txheej txheem kev lees paub los txheeb xyuas txhua qhov kev sib txuas ntawm cov khoom siv, cov dej sib khi, thiab kev ua haujlwm zoo.
