01 General
1.1 Project Background
Lub 630 kVA qhib winding qhuav hom transformer tau xa mus rau South Africa xyoo 2024, lub zog ntsuas ntawm lub transformer yog 630 kVA. Thawj qhov voltage ntawm lub transformer yog 11 kV thiab theem nrab voltage yog 0.55 kV. Peb tsim 125℃C kub nce thiab H-chav tsev rwb thaiv tsev, uas muaj peev xwm raug kev txom nyem 180℃C max kub, muaj zog overload muaj peev xwm, muaj zog luv- Circuit Court kuj, muaj kev ruaj ntseg zoo.
Qhib winding qhuav hom transformers uas tsim los ntawm SCOTECH muaj tsawg chaw ua hauj lwm tawm, tsis muaj suab nrov, muaj zog overload muaj peev xwm, muaj zog luv- Circuit Court kuj, nplaim retardant, tsis yog -combustible thiab non{2}}explosive yam ntxwv, thiab kev nyab xeeb kev ua tau zoo. Siv ntau yam thev naus laus zis, ua kom muaj kev sib haum xeeb zoo, lim kev sib haum xeeb, thiab ua kom lub cev muaj zog ntev. Nws tuaj yeem tiv thaiv kom tsis txhob ya raws, tshuaj tsuag ntsev, corrosion, huab cua tsis kam, ua haujlwm ntev. Siv dav hauv cov chaw ua haujlwm hauv chaw ua haujlwm, siab- cov tsev siab, cov chaw lag luam, tshav dav hlau, chaw nres nkoj, subways, roj platforms thiab lwm qhov chaw ntawm lub zog xa hluav taws xob thiab kev hloov pauv. Peb 630kVA qhuav hom transformer tau tsim los nrog cov thev naus laus zis siab heev thiab txais cov khoom zoo thiab cov khoom uas ua rau muaj kev ntseeg siab zoo thiab lub sijhawm ua haujlwm ntev.

02 Kev tsim khoom
2.1 Core
Cov tub ntxhais siv tau zoo thiab siab -permeability silicon steel ntawv, ntau- cov txheej txheem, bass nrov txo, tsis muaj -load poob. Tus tsim ntawm cov tub ntxhais hlau txais yuav "E-I" hom lossis "ring" qauv. Tus E-Kuv hom tuaj yeem txo cov dej ntws tawm thiab eddy tam sim no poob los ntawm superimposing E-zoo li tus thiab kuv-zoo li tus silicon steel los xij ua ke los tsim ib qho kaw - voj voog sib nqus. Lub annular core ntxiv txo lub zog poob los ntawm kev tsim annular thiab muab txoj hauv kev zoo dua. Txhua daim ntawv ntawm silicon steel yog insulated, feem ntau yog insulating xim los yog coated nrog insulating ntawv, uas txo cov tiam ntawm eddy tam sim no. Cov txheej txheem lamination ntawm cov tub ntxhais hlau superimposes cov nplooj ntawv rau hauv cov khaubncaws sab nraud povtseg kom cov permeability ntawm cov tub ntxhais hlau thaum txo qis hysteresis poob ntawm cov tub ntxhais hlau.
2.2 Cua txias
Cov winding txais yuav qhib thiab tsis yog -cov qauv txheej txheem, uas muaj cov cua kub zoo thiab muaj zog tshaj qhov muaj peev xwm. Qhov tshwj xeeb winding tsim tuaj yeem txo cov hluav taws xob hluav taws xob lub zog ntawm cov windings, yog li txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm rwb thaiv tsev.
2.3 Lub Rooj Sib Tham Kawg
Winding qhov chaw: thawj winding thiab theem nrab winding yog ntsia rau ntawm cov tub ntxhais hlau raws li tus qauv tsim.
Winding kev twb kev txuas: Txuas lub winding davhlau ya nyob twg raws li cov hluav taws xob kos duab los xyuas kom meej qhov kev twb kev txuas yog ruaj khov.
Cov ntaub ntawv rwb thaiv tsev: Muab cov ntaub ntawv rwb thaiv tsev (xws li cov ntawv insulating thiab cov roj insulating) raws li cov qauv tsim kom ntseeg tau tias kev ruaj ntseg ntawm cov rwb thaiv tsev. Kev ntsuas rwb thaiv tsev: kev ntsuas kev tiv thaiv rwb thaiv tsev yog ua los xyuas kom meej tias cov rwb thaiv tsev ua tau raws li cov kev qhia tshwj xeeb.
Cov kiv cua lossis cov cua txias: Nruab lub tshuab hloov pauv cov kiv cua lossis cov cua txias kom ntseeg tau tias lub tshuab cua txias tuaj yeem ua kom cov cua sov tau zoo.
Plhaub fixation: Nruab lub plhaub los yog tus neeg saib xyuas ntawm lub transformer nyob rau hauv qhov chaw kom paub meej tias lub plhaub yog kaw nrog lub ntsiab lub cev ntawm lub transformer.
Cable kev twb kev txuas: Txuas lub siab thiab tsis tshua muaj hluav taws xob cables ntawm lub transformer los xyuas kom meej tias cov hluav taws xob kev twb kev txuas muaj zog thiab ua tau raws li cov qauv kev ruaj ntseg.
Grounding: Ua kev kho av kom ntseeg tau tias cov av ntawm lub tshuab hloov pauv tau zoo.
