01 General
1.1 Project Background
Xa mus rau Tebchaws Meskas hauv 2025, qhov no750kVA kua- puv peb-phase ncoo-mounted transformeryog engineered nyob rau hauv tag nrho ua raws li IEEE Std C57.12.34-2022, ua kom nws zoo- haum rau nruab nrab-voltage faib systems thoob plaws North America.
Qhov no 750 kVA kua- puv transformer nta ib lub voj -feed configuration rau saj zawg zog network kev koom ua ke thiab txhim khu lub zog kev ntseeg tau. Cov neeg tuag- qauv tsim ua kom muaj kev nyab xeeb hauv pej xeem lossis siab- thaj chaw nkag los ntawm kev tshem tawm cov khoom nyob hauv. Lub luj tshib ntes rau kev tiv thaiv overvoltage. Nws tsib - ceg core kev tsim kho tau zoo haum rau xoom- cov kab sib txuas hauv qab tsis sib npaug ntawm cov khoom thauj, txhim kho kev ua tau zoo hauv - lub ntiaj teb kev faib tawm.
FR3 natural ester kua raws li qhov nruab nrab insulating. FR3 yog hluav taws kub - nyab xeeb, biodegradable, thiab ib puag ncig tus phooj ywg lwm txoj rau cov ntxhia roj, muab lub teeb nyem siab thiab ua haujlwm zoo thermal.
Nws yog qhov zoo tagnrho rau cov cheeb tsam hauv nroog, cov chaw ua si, chaw ua lag luam, thiab cov tsev kawm ntawv uas xav tau kev faib tawm hauv av.

02 Kev tsim khoom
2.1 Core
Lub 750kVA, 12.47/0.6kV YNyn0 ncoo-mounted kua-immersed transformer txais ib tug tsib- ceg core tsim los xyuas kom meej kev tuav kom zoo ntawm xoom-flux tshwm sim los ntawm unbalanced loads los yog grounded systems. Cov ceg ceg ntxiv sab nraud muab txoj hauv kev tsis txaus siab rau xoom- cov kab ke sib txuas, ua kom cov rwb thaiv tsev ua tau zoo dua, qis suab nrov, thiab txhim kho kev ntseeg tau raws li qhov tiag - ntiaj teb kev faib tawm network.
2.2 Cua txias
Cov coils rau YNyn0 vector pawg transformer tau ua tiav siv tooj liab conductors -foil winding rau sab LV thiab hlau winding rau HV sab. Cov neeg ua haujlwm tam sim no tshem tawm cov pwm winding tom qab ua kom cov coils ua tau raws li qhov yuav tsum tau muaj qhov ntev thiab rwb thaiv tsev. Kev npaj yog tab tom ua rau cov kauj ruam tom ntej: cov tub ntxhais thiab cov coil sib dhos, qhov twg cov windings yuav raug ntsia rau ntawm cov qauv hlau.
2.3 Tank
Lub tank kaw nrog bolted npog, ua los ntawm cov hlau me me, tau ua tiav nws cov txheej txheem tha xim thiab tab tom tos kev tshuaj xyuas zoo. Cov kws tshuaj ntsuam xyuas yuav xyuas cov xim zaj duab xis thickness, nto smoothness, thiab tag nrho cov tsos. Yog tias muaj teeb meem xws li hlwv, tev, pinholes, pob liab qab, txheej tsis sib xws, lossis khawb, tus saib xyuas kev pleev xim yuav raug ceeb toom thiab rov ua haujlwm dua. Cov kauj ruam tom ntej yog lub tank sib dhos, suav nrog lub tank loj, lub qhov rooj hauv ntej, lub hauv paus skid, thiab enclosure, thiab lwm yam.
2.4 Kev sib dhos zaum kawg
Lub active ib feem los ua ke ntawm 750kVA 12.47 / 0.6kV peb -theem ncoo-mounted transformer tau ua tiav, suav nrog cov tub ntxhais stacking, winding insertion, lead txuas, thiab installation ntawm NLTC (tsis muaj -load tap changer). Tus kws tshaj lij tam sim no tab tom ua qhov kev ntsuas kev tiv thaiv hluav taws xob ntawm cov cua ntsawj ntshab thiab hauv av siv lub tshuab digital megohmmeter txhawm rau txheeb xyuas qhov xwm txheej rwb thaiv tsev ua ntej tsiv mus rau qib tom ntej.
