01 General
1.1 Project Description
50 kVA ib theem ncej mounted transformer tau xa mus rau Guyana xyoo 2025. Lub zog ntsuas ntawm lub transformer yog 50 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 13.8 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.12 / 0.24 kV, lawv tsim ib pawg vector ntawm Ii0.
Qhov no 50 kVA ncej-mounted transformer yog tsim los ua raws li IEEE cov qauv, ua kom ntseeg tau kev ua tau zoo thiab ua haujlwm ntev hauv kev siv sab nraum zoov. Nws nta kev tsim kho muaj zog nrog cov khoom siv tseem ceeb xws li cov cuab yeej siv lub zog los txhim kho kev nyab xeeb los ntawm kev tiv thaiv overpressure tej yam kev mob thiab kev tawm - Circuit Court hloov pauv rau hloov pauv hloov hluav taws xob kom haum raws li qhov xav tau sib txawv. Lub transformer yog nruab nrog lub qhov muag - hom terminals ( eyelet bushings), pab kom muaj kev ruaj ntseg thiab muaj txiaj ntsig kev sib txuas rau cov kab hluav taws xob. Nws tus ncej-mounted tsim optimize qhov chaw siv thaum muab kev faib hluav taws xob zoo nyob rau hauv cov nyob deb nroog, suburban, los yog industrial chaw. Engineered rau kev ua tau zoo thiab kev ua haujlwm ntev, qhov hloov pauv no tsim nyog rau kev siv hluav taws xob thiab kev lag luam, xa lub zog ruaj khov nyob rau hauv ntau yam kev ua haujlwm.

02 Kev tsim khoom
2.1 Core
Lub silicon steel sawb yog spirally mob ntawm lub CNC winding tshuab los tsim ib lub kaw duab plaub los yog toroidal qauv. Kev nruj nruj yog tswj xyuas kom zoo thaum lub sij hawm winding kom tsis txhob muaj kev ntxhov siab -induced magnetic degradation. Annealing yog ua nyob rau hauv ib tug hydrogen cua ntawm 800 ~ 850℃los txo cov neeg kho tshuab kev nyuaj siab thiab kho kom zoo magnetic permeability. Ib sab ntawm cov tub ntxhais yog precision-txiav kom tso cai rau coil insertion, nrog rau qhov txiav nto finely hauv av kom txo tau magnetic tsis kam. Ib leeg-theem ncej-mounted transformers nrog lub qhov txhab cores xa cov kev ua tau zoo dua, qis dua, thiab ua haujlwm ntsiag to, ua rau lawv zoo tagnrho rau cov khoom siv hluav taws xob niaj hnub. Nrog rau kev nce qib hauv cov ntaub ntawv zoo li amorphous hlau, qhov txhab hloov pauv hloov pauv yuav ua lub luag haujlwm tseem ceeb dua hauv cov phiaj xwm ntse yav tom ntej.
2.2 Cua txias
Roj-immersed ncej-mounted transformers feem ntau txais yuav tsawg-voltage (LV) foil winding (tooj liab ntawv) + siab-voltage (HV) hlau winding (tooj liab) configuration.
• LV Winding: Layered copper foil (0.1–2mm tuab) nrog insulating ntawv interleaving, muab qhov chaw siab, ua kom txias, thiab superior luv luv - Circuit Court muaj peev xwm.
• HV Winding: Multi- txheej enameled tooj liab hlau winding, ntxiv dag zog rau cov ntawv insulating thiab roj ducts rau txhim kho dielectric zog thiab kais - hloov yooj.
Cov windings yog concentrically txheej txheem (LV sab hauv, HV sab nraum) thiab tag nrho rau hauv transformer roj, siv ib tug roj - ntawv rwb thaiv tsev system rau txias thiab hluav taws xob cais.
2.3 Tank
Lub -theem ncej- mounted transformer tank yog tsim los ntawm txias- dov steel daim hlau tsim rau hauv cylindrical zoo los ntawm cov menyuam bending tshuab. Sab phab ntsa yog nias- molded nrog nruam corrugated fins thiab precisely welded siv TIG vuam. Lub tank npog yog flange- txuas rau lub cev nrog roj- cov roj hmab tiv thaiv thiab bolted rau kev sib khi. Tag nrho cov welds undergo kerosene penetration test thiab 0.05MPa cua siab to test. Kev kho saum npoo muaj xws li sandblasting ua raws li los ntawm ob-coat painting (epoxy primer + polyurethane topcoat) rau kev tiv thaiv corrosion sab nraum zoov.
2.4 Kev sib dhos zaum kawg
1. Winding Assembly:Xaub lub siab -voltage thiab low-voltage windings mus rau hauv lub hauv paus, ua kom muaj kev sib raug zoo ntawm cov rwb thaiv tsev, thiab ruaj ntseg cov kev txhawb nqa winding.
2. Kev sib txuas hluav taws xob:solder los yog crimp cov hlau lead, txuas tus kais hloov pauv, qhwv cov ntaub ntawv rwb thaiv tsev, thiab kho cov xaim nyob rau hauv qhov chaw.
3. Core-Coil ziab:Muab cov khoom sib dhos ua ke (core thiab windings) rau hauv qhov cub kom qhuav, siv lub tshuab nqus tsev kom tshem tawm cov dej noo, thiab xyuas kom muaj kev tiv thaiv kev tiv thaiv raws li cov qauv.
4. Tank Installation:Nqa cov khoom qhuav qhuav thiab ua tib zoo txo nws mus rau hauv lub tank, ua kom zoo nrog cov pins tso, thiab khi lub hauv paus bolts.
5. Accessory Installation:Mount bushings, siab nyem valve thiab lwm yam accessories, sealing tag nrho cov pob qij txha.
6. Roj Sau & Sealing:Lub tshuab nqus tsev- sau cov roj insulating mus rau qib uas tau teev tseg, tshawb xyuas cov dej xau tom qab kev daws teeb meem, thiab ua tiav kev sib dhos zaum kawg.
