01 General
1.1 Project Background
Xyoo 2025, peb tau xa ob lub 2500kVA hluav taws xob hloov hluav taws xob hauv tsev rau cov neeg siv khoom hauv Tebchaws Meskas kom txhawb nqa lub tshuab hluav taws xob hauv av niaj hnub. Ua kom tau raws li IEEE Std C57.12.34-2022 thiab DOE 2016 cov qauv kev siv hluav taws xob zoo, lub ncoo mounted transformer muaj kev ntseeg siab, txuag hluav taws xob, thiab cov txiaj ntsig ib puag ncig mus ntev.
Chav tsev nta lub voj pub, tuag pem hauv ntej tsim, ua kom muaj kev nyab xeeb thiab kev saib xyuas yooj yim hauv cov cheeb tsam hauv nroog loj. Nws siv FR3 natural ester roj, hluav taws kub - nyab xeeb, biodegradable insulating kua zoo tagnrho rau cov tsev nyob, kev lag luam, thiab cov chaw teeb tsa uas kev nyab xeeb thiab kev ruaj ntseg yog qhov tseem ceeb.
Nrog lub kaw lus kaw thiab sab -mounted low voltage flange qhov hluav taws xob, lub tsev hluav taws xob hloov hluav taws xob no tau zoo rau kev sib txuas hauv av hauv kev hloov kho cov phiaj xwm ntse, cov chaw lag luam, cov chaw ua si, thiab cov chaw siv hluav taws xob. Nws cov hneev taw me me thiab kev ua haujlwm ntsiag to ua rau nws zoo tagnrho rau cov chaw uas muaj qhov chaw nruj thiab txwv tsis pub muaj suab nrov.
Los ntawm kev sib txuas ua haujlwm siab (99.53%), rwb thaiv tsev ruaj khov, thiab hloov pauv hloov hluav taws xob, chav tsev no muab kev ntseeg siab, qis - kho lub zog kho kom haum rau North America cov kev thov daim phiaj.

02 Kev tsim khoom
2.1 Core
Cov tub ntxhais muaj peb ceg tseem ceeb thiab ob txhais ceg pab. Sib nqus flux ntws los ntawm ob lub ntsiab thiab pab ob txhais ceg, muab txoj hauv kev ntxiv uas txhim kho flux kaw. Qhov kev tsim no ua kom ruaj khov ua haujlwm nyob rau hauv qhov tsis sib luag thiab tsis muaj -load tej yam kev mob, txo kev co thiab suab nrov. Lub tsib- ceg tub ntxhais khiav ntsiag to thiab ntseeg tau, ua rau nws zoo tagnrho rau kev faib hauv nroog thiab kev lag luam siv qhov twg tsis muaj suab nrov thiab muaj kev ntseeg siab.
2.2 Cua txias
Cov khoom siv hluav taws xob hauv tsev siv hluav taws xob siv hluav taws xob tsawg-voltage foil winding thiab siab-voltage wire winding nrog ca aluminium conductors kom txhim kho kev ua tau zoo thiab txo qhov poob. Lub kauj yog ua los ntawm txhuas rau nws cov conductivity thiab lub teeb yuag. Nyob rau hauv daim duab, ib tug neeg ua hauj lwm nruj nreem nias phaj screws kom ruaj lub kauj, npaj rau cov kauj ruam tom ntej nias. Qhov no ua kom nruj compression, txhim khu kev ruaj ntseg, txo kev co, thiab boosts kev cia siab thiab efficiency thaum lub sij hawm ua hauj lwm.
2.3 Tank
Qhov peb -theem hluav taws xob hloov hluav taws xob hauv tsev muaj lub thawv me me steel nrog lub hau npog, hmoov-coated nyob rau hauv RAL 9003 dawb rau corrosion kuj. Nruab nrog lifting lugs thiab jacking pads kom yooj yim tuav. Nws dhau 50kPa lub siab xau kuaj rau 12 teev uas tsis muaj qhov to lossis deformation, kom ntseeg tau tias kev sib khi ruaj khov thiab kev ua haujlwm zoo.
2.4 LV Flanged Sab -mounted Bushings
Peb -theem pad mounted transformer nta ib qho hluav taws xob tsawg flanged sab qhov hluav taws xob tsim, tso cai yooj yim thiab ruaj ntseg txuas rau hauv av cables. Sab -mounted LV terminals raug tiv thaiv los ntawm lub thawv kaw lus kaw, kom muaj kev nyab xeeb, qhov chaw- txhim kho tau zoo hauv kev faib hauv nroog thiab kev lag luam hluav taws xob.
2.5 Lub Rooj Sib Tham Kawg
Core & Coil Assembly
Aluminium windings (YNyn0) yog clamped rau hauv cov tub ntxhais rau KNAN txias. Rwb thaiv tsev thiab qhov sib txawv raws li 34.5 kV / 0.63 kV thiab 5.75% impedance specs.
Kev Npaj Tank
Tank coated nrog FR3-resistant xim. Cov khoom tseem ceeb: lub siab nyem valve, roj / lub tshuab nqus tsev vacuum, thiab ntsaws ntsaws nrog qhov chaw nres nkoj siab.
