Qhov hluav taws xob: 12.47 / 0.48kV
Feature: stainless hlau tank
Kev hloov pauv lub zog meej ua kom muaj kev nyab xeeb thiab ruaj khov, raws li peb -theem ncoo- mounted transformers txhawb lub neej yav tom ntej ntawm cov phiajcim ntse!
01 General
1.1 Project Background
300 kVA ncoo mounted transformer tau xa mus rau Asmeskas hauv 2024. Qhov peb theem pad mounted transformer no tau yuav los ntawm Jamaican cov neeg siv khoom, TAK. Nws yog tsim nyog sau cia tias qhov tsawg voltage dual voltage yog qhov tshwj xeeb feature ntawm no transformer. Lub zog ntsuas ntawm lub tshuab hloov pauv yog 300 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 12GrdY / 6.9kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.24 / 0.12kV, lawv tsim ib pawg vector ntawm YNd11, thiab nws yog lub voj pub thiab tuag pem hauv ntej transformer.
Pad mounted transformers, tseem hu ua American -style prefabricated cabins, yog cov khoom siv hluav taws xob sib xyaw ua ke uas sib xyaw ua ke siab -voltage switchgear, transformers, thiab lwm yam khoom faib. Lawv siv cov hloov pauv thiab fuses ua cov cuab yeej tiv thaiv tseem ceeb, uas muaj cov qauv tsim, kev ua haujlwm yooj yim, kev txhim kho yooj yim, thiab cov nqi tu qis. Vim lawv cov hneev taw me me thiab muaj zog yoog tau, American-style lub thawv hloov pauv tau siv dav hauv kev tsim hluav taws xob hauv nroog, kev hloov kho hluav taws xob hauv zej zog, thiab qhov chaw- txwv tsis pub xws li cov chaw lag luam, cov zej zog hauv zej zog, thiab cov phiaj xwm hluav taws xob ib ntus.
Qhov zoo: Compact me me nrog cov qauv sib xyaw ua ke; tag nrho ntim roj tank thiab tag nrho insulated tsim kom muaj kev nyab xeeb thiab txhim khu kev qha; haum rau ob lub nplhaib network thiab lub davhlau ya nyob twg fais fab mov, ua kom yooj yim ua haujlwm thiab txhim khu kev qha fais fab; muaj zog overload muaj peev xwm thiab zoo heev tiv thaiv tam sim ntawd luv luv circuits; superior cuam tshuam tsis kam; lub zog- ua haujlwm tau zoo nrog kev poob qis, kev sib ntsib lossis tshaj cov qauv kev ua haujlwm niaj hnub; cable taub hau muaj peev xwm tuav 200A load tam sim no, nrog rau kev siv tshuab thiab hluav taws xob txuas ntxiv.

02 Kev tsim khoom
2.1 Core
Peb -theem tsib-limb transformer core nta ib lub cim sib nqus hluav taws xob tsim tsim los ntawm peb ceg ceg loj thiab ob sab ceg ceg. Cov windings ntawm cov ceg ceg tseem ceeb nqa cov thawj sib nqus flux, thaum lub caj dab auxiliary yog siv los kaw qhov sib nqus Circuit Court, zoo txo cov dej ntws tawm thiab luv luv -circuit tam sim no.
Core clamps yog cov khoom siv rau kev ruaj ntseg thiab ceev cov tub ntxhais transformer. Lawv feem ntau yog ua los ntawm siab- lub zog tsis yog- cov khoom sib nqus, xws li stainless hlau lossis aluminium alloys tshwj xeeb, los muab cov khoom siv dag zog zoo yam tsis muaj kev cuam tshuam rau cov tub ntxhais sib nqus kev ua haujlwm. Tus tsim ntawm cov clamps tseem yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua kom muaj cua sov kom ntseeg tau tias thermal stability thaum lub sijhawm ua haujlwm.
2.2 Cua txias
YNd11 Connection Group
Lub siab -voltage star kev twb kev txuas muab ib tug nruab nrab point, ua tau raws li cov kev xav tau ntawm unbalanced loads, thaum lub low-voltage delta kev twb kev txuas txo peb harmonics, kom ruaj khov fais fab mov.
Lub sijhawm 11 teev ua haujlwm txo qis kev cuam tshuam kev cuam tshuam hauv lub cev.
Tsawg-Voltage Foil Winding Design
Zoo heev tshav kub dissipation nrog tsawg kub nce, ncua lub transformer lifespan.
Strong luv-circuit resistance thiab uniform inter-tig hluav taws xob xa hluav taws xob, ua kom ntseeg tau kev ua haujlwm.
High-Voltage Wire Winding Design
Compact qauv txuag chaw.
Kev ua haujlwm ruaj khov hluav taws xob nrog kev ruaj ntseg rwb thaiv tsev.
2.3 Tank
Lub tank roj tau txais kev tsim qauv tsim, zoo tiv thaiv huab cua sab nraud thiab ya raws los ntawm kev nkag mus, ua kom lub sijhawm ntev -kev ruaj khov ntawm cov roj hloov pauv thiab txuas ntxiv cov khoom siv lub neej. Tsim kom muaj kev sib haum xeeb thiab qhov chaw-txuag, cov roj tank yog ua los ntawm siab- cov hlau zoo nrog cov neeg kho tshuab siab, muaj peev xwm tiv taus qhov cuam tshuam sab nraud thiab sab hauv. Sab nrauv sab nrauv yog kho nrog tshuaj tsuag txheej lossis kub-dip galvanization, muab kev tiv thaiv corrosion zoo heev rau qhov chaw hnyav xws li cov av noo siab, tshuaj tsuag ntsev, lossis tshuaj lom neeg.
2.4 Kev sib dhos zaum kawg
Core thiab Winding Assembly
Sib sau ua ke cov tub ntxhais kuaj tau ruaj ntseg nrog lub siab - thiab qis -voltage windings, kom ntseeg tau tias hluav taws xob ua tau raws li cov qauv tsim.
Roj Tank Installation
Nruab lub transformer lub cev rau hauv lub tank roj, txuas nrog cov cables, thiab ua tiav cov txheej txheem sealing.
Cov khoom siv sab nrauv Installation
Nruab siab -voltage Cheebtsam xws li load switches thiab tam sim no - txwv fuses, as well as low-voltage output txees and cable terminals.
Roj Filling thiab Leak Testing
Txhaj cov roj insulating, ua cov kev ntsuas siab, thiab tshawb xyuas cov dej xau kom ntseeg tau tias kev sib khi thiab kev ua haujlwm txias.
