01 General

1.1 Project Description

3750/4250 kVAsubstation transformertau xa mus rau Asmeskas siv rau Balling Building, ASB & Bin & Mixing hauv 2025. Lub zog ntsuas ntawm lub transformer yog 3750/4250 kVA nrog KNAN / KNAF txias. Thawj qhov hluav taws xob yog 13.8 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.48 / 0.277 kV, thiab lawv tsim ib pawg vector ntawm Dyn1.

Pebchav tsevsubstation transformeryog lub zog muaj zog thiab txawj ntse daws teeb meem tsim los rau kev ua tau zoo dua thiab kev ntseeg siab hauv cov kab hluav taws xob niaj hnub. Nruab nrog lub tshuab nqus tsev ntsuas lub siab, ntsuas qib kua (nrog rau lub tswb hu), thiab ntsuas ntsuas kub ua kua, nws ua kom muaj kev soj ntsuam tas li ntawm qhov tseem ceeb rau kev ua haujlwm nyab xeeb. Kev tiv thaiv zoo tshaj plaws xws li cov cuab yeej tiv thaiv siab, qhov yuam kev relay, thiab xob laim ntes tiv thaiv kev ua txhaum sab hauv thiab sab nraud surges. Lub tshuab ua kom zoo cua txias nrog cov kiv cua thiab lub tshuab hluav taws xob tswj cov thermal stability, thaum sib xyaw marshalling lub thawv thiab CT lub thawv ua kom tsis muaj kev tswj xyuas thiab ntsuas. Txhawm rau txhim kho kev txav mus los, lub log yooj yim rau kev teeb tsa thiab tso. Engineered rau durability thiab efficiency, no transformer muab uninterrupted fais fab kev faib rau cov khoom siv hluav taws xob, kev lag luam, thiab lub zog tauj dua tshiab - qhov twg innovation ntsib kev ntseeg tau.

02 Kev tsim khoom

2.1 Core

Lub substation transformer core yog tsim los ntawm qib siab -qib, nplej- taw qhia silicon steel laminations, ua tib zoo teem kom txo qis tam sim no poob thiab ua kom pom kev sib nqus flux faib. Lub laminated tsim tau txo qis hysteresis poob, thaum lub kauj ruam -lapse configuration txhim kho txhua yam stability thiab suab nrov txo. Txhua tus tub ntxhais yog precision-engineered los muab qis tsis muaj -load tam sim no, siab permeability, thiab tshwj xeeb thermal kev ua tau zoo, ua kom ntseeg tau lub zog hloov txawm nyob rau hauv hnyav load. Cov tub ntxhais cov qauv muaj zog yog ntxiv rwb thaiv tsev nrog cov txheej txheem ruaj khov los tiv thaiv luv luv -circuiting, xa mus ntev- kev ntseeg siab nyob rau hauv kev thov kev siv hluav taws xob xa tawm.

2.2 Cua txias

Qhov qis-voltage winding siv precision-engineered foil- kev tsim kho kom ua tau zoo tam sim no, txhua yam muaj zog, thiab thermal dissipation. Lub caij no, lub siab -voltage winding txais txheej txheej- cov kab mob tooj liab nrog cov ntawv rwb thaiv tsev interleaved, kom ntseeg tau tias muaj zog dielectric zog thiab luv luv - Circuit Court kuj. Ob lub windings suav nrog radial cua txias ducts thiab cov txheej txheem hloov pauv kom txo qis qhov poob tam sim no, lav ntev - lub sij hawm kev cia siab nyob rau hauv hnyav loads thiab hnyav ua hauj lwm tej yam kev mob.

2.3 Tank

Lub tank yog tsim los ntawm siab- lub zog welded steel daim hlau nrog tiv thaiv- kev kho corrosion, kom ntseeg tau tias muaj kev tiv thaiv txhua yam thiab ntev - lub sij hawm durability. Tank tsim siv cov hlua khi thiab nqa cov hlua kom txhim kho rigidity thiab kev nyab xeeb tuav thaum lub sijhawm teeb tsa. Lub tank nta ib qho kev tsim kho tag nrho nrog gasketed bolted npog, tiv thaiv cov roj to thaum tso cai yooj yim rau kev saib xyuas. Internally, nws lub tsev strategically positioned baffle daim hlau los optimize roj ncig thiab tshav kub dissipation, thaum sab nraud radiators los yog txias fins yog kev koom ua ke rau npaum thermal tswj. Cov kev cai tshwj xeeb xws li hauv av terminals, roj sampling li qub, thiab corrosion- cov xim pleev xim ua tiav raws li IEEE cov qauv, ua rau nws hloov tau rau qhov hnyav sab nraum zoov.

2.4 Kev sib dhos zaum kawg

Lub substation transformer undergoes ib tug precision sib dhos txheej txheem uas integrates cov tub ntxhais, windings, tank, thiab accessories rau hauv ib tug unified system. Cov nplej- taw qhia silicon steel core yog thawj zaug sib sau ua ke nrog pre- insulated laminations, ces precisely ua raws li LV ntawv ci thiab HV txheej windings. Cov windings tau txais kev kho kom qhuav kom ntseeg tau tias kev ua haujlwm zoo ntawm rwb thaiv tsev ua ntej yuav raug ntsia rau hauv qhov tseem ceeb. Cov tub ntxhais -coil los ua ke yog ua tib zoo txo ​​qis rau hauv cov corrosion-cov hlau tsis muaj zog, qhov chaw txias radiators, bushings, thiab cov thawv tswj tau teeb tsa. Cov khoom tseem ceeb xws li cov cuab yeej tiv thaiv siab, ntsuas qhov ntsuas kub, thiab cov thawv marshalling tau raug xaim kawg thiab kev sim ua haujlwm. Lub tsev sib sau ua ke tau txais lub tshuab nqus tsev roj filling, ua raws li kev sim nruj.
