01 General
1.1 Project Background
Lub 630 kVA qhib winding qhuav hom transformer tau xa mus rau South Africa hauv 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. SCOTECH's open winding dry type transformers muaj cov yam ntxwv ntawm lub zog luv luv - Circuit Court tsis kam, kev ua haujlwm me me, kev ua haujlwm siab, me me, tsis tshua muaj suab nrov, thiab feem ntau siv rau hauv qhov chaw uas muaj kev ua haujlwm siab xws li kev tiv thaiv hluav taws thiab tiv thaiv tawg. Kev nyab xeeb, fireproof, tsis muaj kuab paug, tuaj yeem ua haujlwm ncaj qha rau hauv siab load zog. Cov khoom yog H chav kawm, cov khoom siv rwb thaiv tsev yog C chav kawm, luv luv - Circuit Court kuj muaj zog, thiab kev nyab xeeb kev ua haujlwm siab. Kev ua tau zoo thaum tshav kub kub dissipation, muaj zog tshaj qhov muaj peev xwm, luv -lub sij hawm super- muaj peev xwm ua haujlwm nyob rau hauv yuam cua txias. Zoo thiab siab permeability silicon steel, ntau- cov txheej txheem, bass nrov txo, tsis muaj -load poob. SCOTECH tsim qhib winding qhuav hom transformers uas muaj zog huab cua hloov tau, noo noo, ntsev tsuag thiab corrosion kuj, muaj zog huab cua tsis kam thiab kev pab lub neej ntev. 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.
Peb 630 kVA qhib winding qhuav hom transformer tau tsim los nrog cov thev naus laus zis siab heev thiab siv cov khoom zoo thiab cov khoom siv, uas ua rau muaj kev ntseeg tau zoo thiab lub sijhawm ua haujlwm ntev.
Peb xyuas kom meej tias txhua qhov ntawm peb cov khoom xa tuaj tau dhau los ua qhov kev lees paub tag nrho. Peb muab ib qho - kev pab cuam pob los ntawm kev sab laj, hais tawm, tsim khoom, teeb tsa, commissioning, kev cob qhia rau tom qab - kev muag khoom. Peb cov khoom tam sim no ua haujlwm hauv ntau tshaj 50 lub teb chaws hauv ntiaj teb. Peb lub hom phiaj los ua koj tus neeg muag khoom ntseeg siab tshaj plaws nrog rau koj tus khub zoo tshaj plaws hauv kev lag luam!

02 Kev tsim khoom
2.1 Core
Lub luag hauj lwm ntawm qhuav transformer core yog tsim ib tug sib nqus Circuit Court. Yuav kom txo tau qhov poob tam sim no, cov tub ntxhais yog ua los ntawm nyias silicon steel ntawv staggered. Qhov saum npoo ntawm silicon steel ntawv yog coated nrog insulating xim thiab oxidized los tsim ib txheej insulating. Cov tub ntxhais yog tsim los ntawm cov tub ntxhais hlau lub cev, fasteners thiab insulating qhov chaw. Cov tub ntxhais kawm siv ntau- cov txheej txheem los ntawm cov txheej txheem tso rau hauv qhov tseem ceeb. Nyob rau hauv ntau yam kev ua haujlwm, cov tub ntxhais tsis muaj kev hloov pauv mus rau qhov ntev thiab ntev.
2.2 Cua txias
Lub winding ntawm lub transformer yog ua los ntawm fireproof chav H enamelled hlau, uas muaj kev ua tau zoo heev thiab kub dissipation, thiab yog teem kom nruj thiab sib npaug. Thaum winding, cylindrical winding yog siv, thiab qis -voltage winding yog nyob ze rau lub hauv paus txhawm rau tiv thaiv nws los ntawm cov tub ntxhais. Lub high voltage winding yog centrally kaw sab nraum lub low voltage winding. Cov windings feem ntau yog cascading los yog helical tsim los txo cov hlau nplaum to thiab txhim kho qhov ua tau zoo ntawm lub transformer. Lub winding ntawm qhib winding qhuav hom transformer tsis txwv los ntawm lub plhaub kaw thiab muaj peev xwm dissipate tshav kub nyob rau hauv cov huab cua, yog li nws cov cua kub dissipation kev ua tau zoo kuj zoo. Qhov kev tsim no tsim nyog siv rau hauv qhov chaw uas muaj qhov kub thiab txias dua los yog qhov cua zoo dua.
2.3 Lub Rooj Sib Tham Kawg
Kev kho rwb thaiv tsev: Siv cov ntaub ntawv rwb thaiv tsev thiab xyuas qhov tseeb ntawm cov rwb thaiv tsev.
Kev xaim: Nruab cov terminals thiab txuas cov xov hlau kom raug.
