01 General
1.1 Project Description
750 kVA chav tsev substation transformer raug xa mus rau Nicaragua xyoo 2026. Lub zog ntsuas ntawm lub transformer yog 2500 kVA nrog KNAN txias. Qhov siab voltage yog 34.5 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov tsawg voltage yog 0.48 kV, lawv tsim ib pawg vector ntawm Dyn11.
Lub peev xwm ntau dua qhov hloov pauv no yog ib feem ntawm tib lub La India gold processing plant project hauv Nicaragua, ua haujlwm hnyav dua qhov xav tau hauv qhov chaw- suav nrog cov cuab yeej ua haujlwm, conveyors, thiab cov cuab yeej pabcuam uas xav tau lub zog ntau dua. Zoo li nws cov 750kVA counterpart, chav tsev no yuav tsum tiv taus qhov chaw huab cua sov huab cua: kub txog 32.8 degree, txheeb ze av noo nce mus txog 79%, cov dej nag txhua xyoo ntawm 1,239mm, thiab ib puag ncig uas muaj cov kab mob paug plua plav uas dej raws li kev ntxuav hluav taws xob yog txwv.
SCOTECH's 2500kVA unit substation transformer yog engineered rau daim ntawv thov tseeb no. Nws nta lub qhov rooj sab nraum zoov rugged mounted enclosure, KNAN txias, thiab FR3 ntuj ester insulating kua-PCB dawb, hluav taws kub resistant, thiab biodegradable nruab nrab uas outperforms ntxhia roj hauv kev tswj cov dej noo thiab cov ntaub ntawv rwb thaiv tsev, tseem ceeb rau lub sij hawm ntev kev cia siab nyob rau hauv cov huab cua ntub. Lub transformer ua raws li kev tsim qauv seismic raws li RNC 07 thiab ASCE7 22/IBC2024, thiab yog tsim rau 24/7 txuas ntxiv kev pabcuam nrog 25 xyoo tsim lub neej. Cov khoom siv dav dav- suav nrog cov roj thiab cov ntsuas cua kub cua, ntsuas qib ua kua, cov cuab yeej tiv thaiv siab, roj relay, thiab lub tshuab nqus pa- xyuas kom pom kev ua haujlwm tag nrho thiab kev tiv thaiv ntawm lub sijhawm tu ncua. NLTC kais hloov pauv nrog ± 2 × 2.5% thaj tsam ntawm thawj sab haum rau cov kab hluav taws xob sib txawv sib txawv hauv thaj chaw deb mining.
Qhov 2500kVA chav tsev no ua tiav nws cov khoom me me kom npog tag nrho cov spectrum ntawm kev ua cov nroj tsuag cov kev xav tau ntawm lub zog. Ua ke, lawv txhawb nqa SCOTECH txoj kev mob siab rau kev xa tawm lub luag haujlwm tseem ceeb hauv kev daws teeb meem rau cov mining sector hauv cov cheeb tsam nyuaj.

Nws tshawb pom cov roj tsub zuj zuj ua rau muaj kev cuam tshuam me me hauv lub cev thiab cov roj ntsha ntse uas tshwm sim los ntawm qhov tsis ua haujlwm loj. Ua nyob rau hauv lub tswb & cov neeg mus ncig ua si xa cov chaw taws teeb rau PCS / SCADA qhov system: lub tswb ceeb toom tau tshwm sim rau cov pa roj qeeb qeeb, thaum cov lus txib mus txawv tebchaws tau qhib rau hauv cov roj surge los ntawm cov teeb meem sab hauv loj. Nws muab cov lus ceeb toom thaum ntxov tiv thaiv kev puas tsuaj ntawm rwb thaiv tsev, kub qhov chaw overheating thiab sab hauv arcing faults.
2.5 Roj Conservator
Lub steel fabricated roj conservator (expansion tank) yog mounted rau ntawm lub transformer, compensating roj ntim variation tshwm sim los ntawm kub hloov. Nws tuav ruaj khov siab zoo nyob rau hauv lub ntsiab tank, txo kev sib cuag ncaj qha ntawm insulating roj thiab cua, thiab slows roj oxidation laus. Ib qho kev qhia qib roj sib xyaw nrog lub tswb nrov saib xyuas cov roj ntim ntawm lub sijhawm; high / low oil level tswb ceeb toom tuaj yeem xa mus rau cov chaw taws teeb saib xyuas lub davhlau ya nyob twg. Fill qhov chaw nres nkoj, ntws ntsaws thiab sampling nozzle yog npaj ua ntej rau kev rov ua cov roj, piv txwv thiab tso dej ua haujlwm ntawm qhov chaw.
2.6 Terminal Thawv
Lub auxiliary davhlau ya nyob twg lub thawv yog ib tug gasketed, lockable steel enclosure rau lwm yam Circuit Court thaiv. Ua ntej cim lub davhlau ya nyob twg thaiv kom haum rau txhua qhov kev tiv thaiv hluav taws xob hluav taws xob hluav taws xob, suav nrog Buchholz relay, lub siab nyem valve, ntsuas roj kub thiab ntsuas qhov ntsuas kub. Nws cais cov hluav taws xob hluav taws xob loj hauv hluav taws xob los ntawm kev saib xyuas hluav taws xob tsis tshua muaj hluav taws xob & lub tswb hluav taws xob, muab cov kab hluav taws xob txhim khu kev qha rau kev tswj cov kab hluav taws xob nkag, thiab ua kom cov kev sib txuas sib txuas tiv thaiv sab nraum zoov plua plav thiab noo noo, ua kom yooj yim sib txuas nrog cov nroj tsuag PLC thiab SCADA systems.
2.7 Tam sim no Transformer Outlet Box
Dedicated CT qhov hluav taws xob lub thawv tsev ob lub terminals ntawm ua nyob rau hauv tam sim no transformers. Nws cais CT cov kab txuas txuas ntxiv los ntawm cov khoom siv hluav taws xob loj. Kos luv luv Circuit Court terminals yog muab rau kev nyab xeeb CT Secondary luv Circuit Court ua haujlwm thaum lub sij hawm commissioning thiab txij nkawm. Gland daim hlau yog tshwj tseg rau kev tiv thaiv kev ntsuas cable nkag. Qhov kev sib koom ua ke no tsis txhob muaj kev pheej hmoo ntawm kev xaim hluav taws xob, lav cov neeg ua haujlwm kev nyab xeeb thiab ua kom cov teeb liab ruaj khov rau kev ntsuas thiab kev tiv thaiv relays.
2.8 Zero-theem Bushing (Neutral Bushing)
Zero-theem nruab nrab bushing yog tsim los rau cov khoom siv hauv av uas tsis tshua muaj hluav taws xob tsis muaj hluav taws xob. Nws muab cov rwb thaiv tsev ruaj khov thiab kev txhawb nqa tshuab rau nruab nrab tus neeg xyuas pib tawm, nrog rau kev nkag mus deb txaus tsim nyog rau sab nraum zoov ua paug mining. Nws yog tag nrho sib xws nrog 4 xaim hluav taws xob tsis tshua muaj hluav taws xob faib qhov system, thiab ua kom muaj kev ruaj ntseg nruab nrab cable txiav. Zoo sealing gaskets tiv thaiv dej los nag thiab noo noo nkag ntawm lub tank nkag mus sib koom ua ke.
2.9 Lub Radiator
Modular phaj hom radiators txais kev ua haujlwm siab kub dissipation qauv rau KNAN (Kernel Natural Air Natural) txias hom. Radiator seem txuas nrog lub tank loj ntawm kev cais npauj npaim li qub; tus kheej lub tsev txhab nyiaj radiator tuaj yeem raug cais tawm rau kev hloov pauv yam tsis muaj cov roj puv tank hloov pauv. Optimized oil flow duct layout txhim khu ntuj convection heat exchange, zoo dissipates tshav kub generated los ntawm cov tub ntxhais thiab winding losses nyob rau hauv tas li ntawd mus load ua hauj lwm, thiab ua rau winding & kub qhov chaw kub nce nyob rau hauv IEEE cov kev txwv rau 24 7 365 tas mus li lub voj voog nyob rau hauv lub tropical ambient kub.
03 Kev Xeem
Txhua chav ua tiav tag nrho lub Hoobkas lees paub kev xeem (FAT) ua raws li ANSI/IEEE C57.12.00 2021 & C57.12.90 2021 ua ntej xa khoom.
