2000 kVA transformer rau qhov ruaj khov thiab ua haujlwm tau zoo hauv cov roj regenerated ua cov nroj tsuag
01 General
1.1 Project Description
Qhov no transformer yog xa mus rau America nyob rau hauv 2024 thiab tsim raws li tus txheej txheem thoob ntiaj teb IEC 60076-1:2011. Nws yog 2 MVA kua-immersed transformer nrog high / low voltage ntsuam xyuas ntawm 11 kV / 0.433 kV thiab ib pab pawg Dyn11 vector, kom ntseeg tau tias muaj kev lag luam hluav taws xob faib hluav taws xob thiab kev ua haujlwm zoo ntawm theem siab thiab qis voltage sab.
Qhov no transformer yog tsim los rau ib tug regenerated roj ua cov nroj tsuag, tuav pov tseg roj. Nws muab lub zog ruaj khov thiab txhim khu kev qha rau cov khoom siv txuas ntxiv xws li twj tso kua mis, cua sov, thiab compressors. Nrog 2 MVA muaj peev xwm thiab NLTC ± 2 × 2.5% voltage hloov, nws ua kom ruaj khov tso zis hluav taws xob txawm tias nyob rau hauv cov khoom hloov pauv.
Ua ntej, lub tshuab hluav taws xob faib hluav taws xob tuaj yeem muab ob qho tib si -theem thiab peb-theem khoom. Kev sib txuas Dyn11 muab peb-theem plaub- xaim tawm. Ib zaug -theem loads ua haujlwm yam tsis ua rau muaj qhov tsis sib xws. Peb -theem tshuab tau txais lub zog txaus.
Thib ob, kev teeb tsa cov nroj tsuag xav tau lub peev xwm tam sim no thiab hloov tau yooj yim cable txuas. Peb cov qauv tsim suav nrog lub siab-voltage cable box muaj peev xwm ua tau raws li 16 × 1C 630 mm² XLPE / PVC tooj liab cables thiab qis-voltage tooj liab busbars rau cov ceg sib txuas, ua kom yooj yim installation thiab yav tom ntej nthuav dav.
Thaum kawg, kev lag luam kev lag luam yuav tsum tau ua kom txias txias thiab tsis muaj zog poob. Lub transformer's ONAN cua txias, tooj liab windings, thiab kua rwb thaiv tsev ua kom ntseeg tau kev ua haujlwm nyob rau hauv ib puag ncig kub ntawm -25℃txog 40℃. Nrog rau qhov tsis muaj load poob ntawm 1.94 kW, load poob ntawm 18.3 kW, thiab 5% impedance, transformer ua tiav qhov sib npaug ntawm kev ua tau zoo, kev nyab xeeb, thiab kev ua haujlwm thermal tsim nyog rau kev lag luam txuas ntxiv.

02 Kev tsim khoom
2.1 Core
Cov tub ntxhais laminations tau ua tib zoo xaiv hauv cov tuab kom sib npaug ntawm kev ua tau zoo thiab tus nqi, nrog cov kauj ruam - cov pob qij txha thiab cov mitered ces kaum kom txo tau qhov sib txawv ntawm huab cua thiab sib nqus tsis kam. Grain-oriented steel aligns magnetic domains rau qhov poob qis, thaum lub stacking meej ua kom txhua yam ruaj khov thiab kev vibration tsawg. Cov qauv tsim no txhawb kev txhim khu kev qha, hloov hluav taws xob zoo rau nruab nrab thiab siab -voltage transformers.
2.2 Cua txias
Lub tshuab hluav taws xob faib hluav taws xob muaj peb -theem tooj liab windings tsim los rau kev hloov hluav taws xob txhim khu kev qha thiab tsis muaj hluav taws xob poob. Cov windings tau raug npaj thiab insulated los tiv thaiv thermal thiab mechanical kev nyuaj siab, txhawb kev ua haujlwm tas mus li nyob rau hauv ib puag ncig kub ntawm -25℃txog 40℃. Nrog rwb thaiv tsev chav kawm A thiab Dyn11 vector pawg, cov coils ua kom ruaj khov voltage, ua haujlwm siab, thiab ua haujlwm ntev ntev hauv kev siv hluav taws xob faib hluav taws xob.
2.3 Tank
Cov bushings yog nyob rau sab saum toj ntawm lub tank thiab them nrog lub thawv cable rau kev tiv thaiv. Lub thawv khaws cov bushings thiab keyboards kom tsis txhob puas thiab nag. Lub tank yog kaw thiab ntim nrog huv transformer roj. Cov roj muab rwb thaiv tsev thiab tshem tawm cov cua sov. Qhov kev tsim no ua kom lub tshuab hloov pauv muaj kev nyab xeeb, txhim khu kev qha, thiab ntev - siv tau ntev hauv kev lag luam.
2.4 Terminal Txee
Lub hwj chim faib transformer nta cais cov thawv rau sab siab thiab tsis tshua muaj hluav taws xob, nrog cov bushings txuas ntawm lub tank mus rau lub thawv cable kom yooj yim cable txuas. Lub siab- lub thawv hluav taws xob muaj txog li 16 × 1C 630 mm² XLPE / PVC tooj liab cables, thaum qis -voltage sab suav nrog 4 tooj liab busbars rau yav tom ntej ceg txuas. Ob lub thawv kom muaj kev nyab xeeb, txhim khu kev qha, thiab txhim khu kev qha hluav taws xob.
2.5 Kev sib dhos zaum kawg
1. Winding los ua ke: Raws li kev tsim qauv, windings ntawm qhov ntau thiab tsawg tau raug mob rau hauv cov tub ntxhais transformer, nrog rau ob qho tib si thawj thiab theem nrab windings. Cov txheej rwb thaiv tsev yog muab tso rau nruab nrab ntawm cov coils.
2. Kev kho rwb thaiv tsev: Cov windings tau kho nrog cov kua roj vanish thiab ci kom ntseeg tau tias kev ua haujlwm zoo ntawm rwb thaiv tsev.
3. Kev teeb tsa ntawm lwm yam khoom siv: Roj ntsuas kub ntsuas (OTI), siab nyem valve, Buchholz relay, roj qib ntsuas, tsis muaj load kais hloov pauv, lub thawv cable, lub davhlau ya nyob twg, thiab lwm yam.
4. Cov roj filling: Sau lub tank transformer nrog cov roj insulating kom txog thaum qhov chaw sab hauv puv puv thiab cov roj qib raws li tus qauv xav tau.
