01 General
1.1 Project Description
500 kVA ncoo mounted transformer tau xa mus rau Jamaica hauv 2025. Lub zog ntsuas ntawm lub transformer yog 500 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 24/13.8 * 13.8D * 12/6.9 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.416 / 0.24 * 0.24D / 0.12 kV, lawv tsim vector pawg ntawm YNyn0 thiab YNd11.
Peb lub ncoo-mounted transformer yog ib qho compact, tag nrho cov khoom siv hluav taws xob xa hluav taws xob tsim los rau kev ntseeg siab, kev nyab xeeb, thiab kev ua haujlwm zoo hauv nroog thiab chaw lag luam. Engineered rau seamless kev koom ua ke rau hauv daim phiaj niaj hnub, nws muaj qhov tawm ntawm - Circuit Court changer thiab dual voltage hloov rau kev ua haujlwm hloov tau yooj yim, tso cai yooj yim hloov voltage yam tsis muaj kev cuam tshuam.
Txhawm rau txhim kho kev tiv thaiv, chav tsev suav nrog lub luj tshib ntes thiab thauj khoom - rhuav lub luj tshib txuas, ua kom muaj kev nyab xeeb kev sib txuas thiab kev tawm tsam. Kev pub-thru insert ua rau kev tswj xyuas cov kab hluav taws xob zoo, thaum saib xyuas qib siab yog muab los ntawm lub ntsuas kub ntawm cov roj, ntsuas qib ua kua, thiab ntsuas lub tshuab nqus tsev rau qhov tseeb- lub sijhawm kuaj mob.
Kev nyab xeeb yog qhov tseem ceeb nrog Bay -O-Net fuse thiab tam sim no- txwv fuses los tiv thaiv overloads, nrog rau kev hloov pauv rau kev sib cais kom ruaj ntseg thaum tu. Ua kom muaj kev tiv thaiv ib puag ncig hnyav, lub tshuab hloov pauv no muab kev cia siab rau kev ua haujlwm nrog kev saib xyuas tsawg kawg nkaus - zoo tagnrho rau kev siv hluav taws xob, kev lag luam, thiab kev siv hluav taws xob tauj dua tshiab.

02 Kev tsim khoom
2.1 Core
Lub transformer nta ib tug siab -efficiency stacked hlau core tsim los ntawm premium grain-oriented silicon steel laminations. Txhua lub lamination yog qhov tseeb laser-txiav thiab txheej nrog cov kauj ruam sib txuas- ceg tawv pob qij txha kom txo tau qhov sib nqus flux to thiab txo tsis muaj - thauj khoom poob. Cov tub ntxhais yog coated nrog ib txheej insulating oxide los tiv thaiv eddy tam sim no, thaum nws compact stacked tsim txhim kho txhua yam kev ruaj ntseg thiab txo qis suab nrov - tseem ceeb rau kev teeb tsa hauv nroog. Rigorously annealed rau kev pom zoo sib nqus permeability, cov tub ntxhais no ua kom lub zog zoo hloov mus rau ob qhov kev teeb tsa hluav taws xob, tswj kev ua haujlwm txawm tias nyob hauv cov khoom hloov pauv.
2.2 Cua txias
Lub LV ntawv ci winding siv tooj liab sawb, kom ntseeg tau tias muaj kev faib tawm tam sim no, zoo dua luv luv -circuit resistance, thiab txhim kho cua sov dissipation. Meanwhile, HV txheej winding txais yuav insulated tooj liab conductors raug mob nyob rau hauv concentric discs, nrog interleaved kraft ntawv rau graded dielectric zog. Cov txheej txheem hloov pauv tau siv los txo qis qhov poob qis, thaum axial thiab radial txias ducts optimize thermal tswj.
2.3 Tank
Lub tank transformer yog ib qho muaj zog, corrosion{0}}resistant steel enclosure featuring 3D corrugated phab ntsa rau roj expansion thiab integrated cooling fins rau passive tshav kub dissipation. Nrog rau tag nrho welded, kuaj radiographically tsim, nws suav nrog ua ntej -drilled cable ports nrog grounding bosses, thiab ua tau - hauv lifting / forklift ntsiab lus. Sab hauv suav nrog baffle daim hlau kom pom cov roj ntws zoo, thaum UV- cov xim epoxy resistant kom ntev -lub sij hawm ua haujlwm nyob rau hauv ib puag ncig sab nraum zoov.
2.4 Kev sib dhos zaum kawg
Kev sib dhos zaum kawg ntawm lub ncoo no -mounted transformer integrates core-coil assembly, tank, thiab accessories rau hauv ib qho kev sib koom ua ke. Cov tub ntxhais qhuav qhuav- chav tsev winding tau ua tib zoo txo qis rau hauv qhov corrosion-cov hlau tsis muaj zog, ua raws li kev teeb tsa ntawm bushings, txias fins, thiab tswj cov khoom. Cov kauj ruam tseem ceeb muaj xws li:
• Roj filling nyob rau hauv lub tshuab nqus tsev vacuum kom tiav rwb thaiv tsev impregnation
• Mechanical alignment ntawm load break keyboards & cable connectors
• Kev sim ua haujlwm ntawm txhua yam khoom siv saib xyuas (gauges, tswb)
