01 General
1.1 Project Description
75 kVA peb theem pad mounted transformer tau xa mus rau Asmeskas xyoo 2025. Lub zog ntsuas ntawm lub transformer yog 75 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 23GRDY / 13.28 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.208y / 0.12 kV, lawv tsim ib pawg vector ntawm YNyn0.
Pad-mounted transformers yog compact, hauv av-theem hluav taws xob faib chav tsev tsim kom muaj kev nyab xeeb thiab siv hluav taws xob xa hluav taws xob hauv nroog, suburban, thiab chaw lag luam. Encased nyob rau hauv ruaj, tamper- tiv thaiv enclosures, cov transformers no muab kev ntseeg siab voltage hloov dua siab tshiab thaum txo hneev taw thiab ib puag ncig. Lawv cov hauv qab no - qhov muag - theem kev teeb tsa ua rau lawv zoo tagnrho rau qhov chaw - txwv tsis pub cov kab hla saum taub hau tsis zoo lossis tsis zoo nkauj.
Engineered rau ob qho tib si kev nyab xeeb thiab kev ua tau zoo, niaj hnub ncoo- mounted transformers feature advanced rwb thaiv tsev systems, corrosion{1}}cov ntaub ntawv resistant, thiab xaiv ntse soj ntsuam muaj peev xwm rau tiag tiag - lub sij hawm kuaj mob. Txawm hais tias lub zog siv hluav taws xob hauv zej zog, cov chaw lag luam, lossis cov chaw tsim khoom, cov chav no xa cov kev ua haujlwm ntsiag to nrog cov kev xav tau txo qis dua piv rau cov ncej qub- mounted lwm txoj.

02 Kev tsim khoom
2.1 Core
Lub ncoo no-mounted transformer nta ib qho tshiab tsib- lub cev nqaij daim tawv nqaij nrog peb lub caj dab winding (A / B / C theem) thiab ob lub flux- rov qab nqua, xa cov khoom sib nqus zoo dua thiab ua haujlwm zoo. Lub seamless kauv-mob nplej- taw qhia silicon steel core txo tsis muaj-load poob los ntawm 25-30% piv rau cov qauv tsim.
Cov txiaj ntsig tseem ceeb muaj xws li:
• Txhim kho qhov sib npaug thiab luv -circuit tiv taus
• Ultra- suab nrov tsawg thiab cua sov tsawg heev
2.2 Cua txias
Qhov no peb winding transformer nta ib tug optimized tsim nrog aluminium foil tsawg-voltage windings thiab tooj liab hlau siab-voltage windings, xa superior efficiency thiab thermal kev ua tau zoo. Qhov thib peb winding muab cov kev cai hloov hluav taws xob hloov pauv lossis muaj peev xwm pab txhawb lub zog. Kev sib xyaw ua ke ntawm cov ntawv ci thiab hlau winding thev naus laus zis, chav tsev compact no muaj cov kev faib tawm zoo tshaj plaws tam sim no, luv luv -circuit tiv taus, thiab tshav kub dissipation - ua rau nws zoo tagnrho rau niaj hnub fais fab kev faib tes hauj lwm uas yuav tsum tau txhim khu kev qha peb winding transformer kev daws teeb meem hauv kev siv hluav taws xob, kev lag luam thiab kev lag luam.
2.3 Tank
Qhov kev hloov pauv no muaj lub zog ruaj khov, huab cua tsis muaj roj tank tsim los ntawm qib siab -qib corrosion- cov hlau tsis muaj zog rau kev ua haujlwm zoo tshaj plaws hauv kev teeb tsa sab nraum zoov. Cov roj tank suav nrog ntau yam kev tsim kho kev nyab xeeb xws li:
• Leak- pov thawj welded seams nrog siab- kuaj kev ncaj ncees
• Expansion conservator nrog roj theem taw qhia rau kev tswj thermal
• Tiv thaiv corrosion los ntawm sandblasting thiab multi- txheej epoxy txheej
2.4 Kev sib dhos zaum kawg
1. Winding Installation:Precisely mount lub HV / LV windings mus rau lub qhov txhab ntawm lub qhov txhab, xyuas kom zoo rwb thaiv tsev kawm ntawv.
2. Kev sib txuas hluav taws xob:Txuas winding ua rau kais hloov pauv, bushings, thiab lwm yam khoom, ces ruaj ntseg thiab kuaj conductivity.
3. Core-Coil ziab:Muab cov khoom sib dhos ua ke rau hauv qhov cub kom qhuav rau lub tshuab nqus tsev kom tshem tawm cov dej noo thiab txhim khu kev rwb thaiv tsev.
4. Tank Insertion:Hoist thiab muab qhov chaw qhuav qhuav rau hauv lub tank, ua kom nws ruaj khov thaum tswj kom zoo rwb thaiv tsev clearance.
5. Accessory Installation:Txuas cov bushings, cov cuab yeej tiv thaiv siab, roj ntsuas, thiab lwm yam, thiab kaw tag nrho cov interfaces.
6. Roj Sau & Sealing:Lub tshuab nqus tsev- sau cov roj insulating mus rau qib uas tau teev tseg, xyuas cov roj zoo thiab lub tank nruj, tom qab ntawd ua tiav kaw.
