Peev xwm: 6MVA
Lub Zog: 33/2.2kV
Feature: Kub-dip galvanized radiator
Ua tau zoo thiab txhim khu kev qha 6 MVA roj-immersed transformers rau lub tshuab inverter, xa cov hluav taws xob muaj kev nyab xeeb, poob qis, thiab kev ua haujlwm ruaj khov hauv South Africa qhov chaw sab nraum zoov.
01 General
1.1 Project Description
Qhov no 6MVA roj- rausfais fab mov transformertau xa mus rau South Africa hauv 2024 rau siv hauv inverter systems. 6 MVA hluav taws xob hloov hluav taws xob muaj peev xwm ntsuas ntawm 6000 kVA, thawj qhov hluav taws xob ntawm 33 kV, thiab qhov nruab nrab ntawm 2.2 kV. Nws nruj me ntsis ua raws li IEC 60076 tus qauv
Txawm hais tias inverters tuaj yeem hloov DC lub zog rau hauv AC lub zog, daim phiaj hluav taws xob feem ntau siab tshaj qhov inverter tuaj yeem tiv taus. Txhawm rau kom muaj kev nyab xeeb kev ua haujlwm, peb lub tshuab hloov pauv tau nqis los ntawm kab hluav taws xob siab (33 kV) mus rau 2.2 kV tau txais rau lub inverter. Lub transformer tseem muab hluav taws xob cais tawm, kev sib haum xeeb kev sib raug zoo, thiab kev tiv thaiv kev tiv thaiv, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov inverter thiab kab sib chaws.
Nws boasts siab ua hauj lwm efficiency. Tsis muaj- load poob qis li 6.2 kW, thiab loaded poob qis li 39 kW, txo kev siv hluav taws xob thiab cov nqi khiav lag luam. A 7% impedance kom ruaj khov voltage nyob rau hauv luv luv -circuit tej yam kev mob, thiab cov tooj liab windings muaj zoo conductivity, tiv thaiv ob lub inverter thiab daim phiaj.
Lub 6 MVA hluav taws xob hloov hluav taws xob tau ntim nrog PCB-cov roj ntxhia tsis muaj roj, ua kom muaj kev nyab xeeb ib puag ncig. Lub tshuab cua txias siv lub tshuab cua txias thiab nta lub kub-dip galvanized radiator. Qhov no ua kom cov cua sov ua kom zoo thiab muaj zog tiv thaiv huab cua, ua rau lawv zoo tagnrho rau South Africa qhov chaw sab nraum zoov.
Cov khoom siv txheem muaj xws li lub ntsuas roj ntsuas, lub siab nyem valve, roj thiab cua ntsuas kub ntsuas cov cuab yeej, Buchholz relay, thiab lub tshuab ua pa, ua kom muaj kev nyab xeeb thiab ruaj khov thiab txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv. Nrog nws cov kev ua haujlwm siab, kev poob qis, thiab kev tsim qauv zoo, qhov no 6MVA roj -immersed fais fab transformer tsis yog tsuas yog ib qho kev xaiv zoo tshaj plaws rau inverter daim phiaj- txuas tshuab, tab sis kuj yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob tshiab.

02 Kev tsim khoom
2.1 Core
Peb nruj me ntsis ua raws li cov qauv tsim, qauv, thiab cov txheej txheem tsim khoom rau txhua kauj ruam, ua kom cov tub ntxhais sib dhos ua tau zoo, ruaj ntseg kev sib txuas ntawm qhov chaw nyob, thiab txhim khu kev qha hauv av. Los ntawm kev tswj hwm nruj no, peb cov cores hlau ua tiav qhov poob qis, txo lub suab nrov, lub zog rwb thaiv tsev siab, thiab muaj zog luv luv -circuit resistance, kom ntseeg tau ntev - lub sij hawm txhim khu kev qha transformer.
2.2 Cua txias
Coil winding yog txheej txheem tseem ceeb. Peb siv high- tooj liab zoo, kom ntseeg tau zoo heev conductivity thiab mechanical zog. Thaum lub sij hawm winding, peb tuav cov rwb thaiv tsev zoo ib yam, qhov sib nrug sib xws, thiab nruj, cov txheej txheem zoo kom tsis txhob muaj cov hotspots thiab rwb thaiv tsev tsis ua haujlwm. Tom qab winding, coils yog zoo li tus, ruaj, thiab rwb thaiv tsev, nrog nruj zoo soj ntsuam, kom ruaj ntseg nyob rau hauv luv luv - Circuit Court, thermal, thiab hluav taws xob stresses thaum ua tau raws li Dyn11 kev twb kev txuas yuav tsum tau.
2.3 Tank
Lub phaj-hom radiator yog kub-dip galvanized thiab pleev xim rau hauv C12 avocado ntsuab. Thaum lub sij hawm lub hwj chim transformer roj tank thiab radiator ntau lawm, tag nrho cov welds tau ua tib zoo ua kom tsis txhob muaj qhov xau, txheeb xyuas los ntawm kev ntsuas cua ntawm 30 kPa rau 8 teev. Sab hauv thiab sab nrauv yog kho los tiv thaiv corrosion, lav ntev -lub sij hawm durability thiab txhim khu kev qha tshav kub dissipation nyob rau hauv kev pab cuam.
2.4 Kev sib dhos zaum kawg
Tom qab cov tub ntxhais transformer thiab windings tau sib sau ua ke, chav tsev tau muab tso rau hauv lub tshuab ziab khaub ncaws. Thaum qhuav, nws yog lifted thiab ntsia rau hauv lub tank roj. Lub tshuab hloov pauv no tau nruab nrog cov khoom siv tag nrho, suav nrog lub phaj- hom radiator, ntsuas qib roj, siab nyem valve, ntsuas roj kub, Buchholz relay, roj conservator, breather, tsis muaj -load tap changer, thiab winding temperature indicator. Tag nrho cov khoom siv tau raug teeb tsa raws li peb cov kev cai tsim khoom nruj, nrog kev sib txuas zoo thiab muaj kev sib koom ua ke. Tom qab kev teeb tsa cov khoom siv, cov txheej txheem sib dhos ua tiav nrog cov roj filling thiab sealing, kev sib txuas hluav taws xob thiab kev sim, thiab tshuaj xyuas cov tsos thiab cov cim.
