01 General
1.1 Project Description
630 kVA qhuav hom transformer tau xa mus rau South Africa hauv 2025. Lub zog ntsuas ntawm lub transformer yog 630 kVA nrog ONAN / ONAF txias. Thawj qhov hluav taws xob yog 6.6 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.55 kV, lawv tsim ib pawg vector ntawm Dyn11.
Cast Resin Dry Type Transformer yog ib qho kev txiav - ntug hluav taws xob tsim los rau kev nyab xeeb, kev ua haujlwm zoo, thiab kev ntseeg siab. Tsis zoo li cov roj ib txwm siv- cov tshuab hloov pauv, nws siv cov nplaim hluav taws xob- cov khoom siv hluav taws xob epoxy los ntim cov windings, tshem tawm cov kev pheej hmoo ntawm cov roj xau, hluav taws kub, thiab kev puas tsuaj ib puag ncig.
Qhov zoo tshaj plaws rau kev teeb tsa sab hauv tsev, cov tshuab hloov pauv no ua haujlwm ntsiag to, yuav tsum muaj kev saib xyuas tsawg, thiab tiv taus cov dej noo, plua plav, thiab corrosive ib puag ncig.
Nrog zoo thermal stability thiab tus kheej -extinguishing zog, lawv xyuas kom meej tsis muaj kev cuam tshuam lub hwj chim nyob rau hauv cov kev siv tseem ceeb xws li cov tsev lag luam, tsev kho mob, cov ntaub ntawv chaw, thiab cov nroj tsuag muaj. Xaiv lub Cast Resin Dry Type Transformer txhais tau hais tias kev nqis peev hauv kev huv, eco- tus phooj ywg, thiab ntev - lub zog xa hluav taws xob kav ntev uas tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm.

02 Kev tsim khoom
2.1 Core
Cov tub ntxhais hom transformer tsim nrog siab -permeability txias- dov silicon steel laminations nyob rau hauv ib kauj ruam -lap stacking configuration kom txo hysteresis thiab eddy tam sim no poob. Lub Core Hom qauv ua kom ntseeg tau tias txawm tias winding faib thiab txhim kho cov cua sov. Nrog rau cov txheej txheem tiv thaiv- corrosive rwb thaiv tsev, nws muab kev ua haujlwm ntsiag to, qhov kub tsis tshua muaj siab, thiab txhim kho lub zog ua haujlwm rau kev ua tau zoo.
2.2 Cua txias
Lub transformer nta epoxy resin windings, kom ntseeg tau superior rwb thaiv tsev thiab txhua yam muaj zog. Lub HV / LV windings yog ua los ntawm txhuas conductors nrog interlayer rwb thaiv tsev rau kev txhim kho dielectric zog. Bushes nyob rau hauv lub transformer yog ntsia ntawm winding terminals rau kev ruaj ntseg hluav taws xob sib txuas thiab yooj yim txij nkawm. Cov windings yog noo noo- pov thawj thiab plua plav- tiv taus, zoo tagnrho rau ib puag ncig hnyav.
2.3 Lub Rooj Sib Tham Kawg
Lub transformer txais kev tsim qauv siab heev, muaj cov epoxy-cov cam khwb cia windings thiab cov kauj ruam-lapped cores sib sau ua ke nrog cov khoom siv hluav taws xob tiv thaiv hluav taws xob. Chav tsev sib xyaw ua ke nrog lub ntsuas kub ntse thiab cov kiv cua txias uas tuaj yeem kho cov cua ntws raws li kev thauj khoom. Nrog rau tag nrho cov rwb thaiv tsev, corrosion- tiv thaiv bushings thiab terminals, nws qhib - ncej qauv nrog optimized airflow channel kom ua tau zoo cua sov dissipation rau kev lag luam txhim khu kev qha nyob rau hauv ntau yam load.
