167 KVA Transformer Hluav Taws Xob Ncej-13.8/0.24/0.12 KV|Guyane xyoo 2025

01 General

1.1 Project Description

167 kVA uatransformer hluav taws xob ncejtau xa mus rau Guyana xyoo 2025. Qhov ntsuas lub zog ntawm lub transformer yog 167 kVA nrog ONAN txias. Qhov siab voltage yog 13.8 kV nrog ± 2 * 2.5% tapping ntau (NLTC), qhov tsawg voltage yog 0.12 / 0.24 kV, lawv tsim ib pawg vector ntawm Ii0.

Lub 167 kVA, ib qho -theem ncej- mounted transformer sawv cev rau ib qho kev txhim khu kev qha thiab muaj txiaj ntsig zoo rau cov khoom siv hluav taws xob siv hluav taws xob, tsim ua kom qis qis qis qis qis ntawm 13.8 kV mus rau qhov qis -voltage split-theem tawm ntawm 120/240 EE nrog ANSI tsim thiab tsim tawm tag nrho / 240 V. C57.12.20 thiab lwm yam IEEE C57 series cov qauv, qhov hloov pauv no ua haujlwm tseem ceeb rau kev faib hluav taws xob hauv cov zej zog hauv zej zog, cov phiaj xwm hluav taws xob nyob deb nroog, cov chaw lag luam teeb pom kev zoo, thiab cov ntawv thov kev ua liaj ua teb, muab kev ruaj khov thiab siab siab -cov khoom siv hluav taws xob zoo nrog kev ua haujlwm tsawg tsawg.

Lub transformer hluav taws xob ncej nta cov roj muaj zog-immersed, nws tus kheej-txias kev tsim kho nrog ONAN (Oil Natural Air Natural) txias, ua kom muaj kev ua haujlwm tsis tu ncua raws li xav tau sab nraum zoov ncej-mounted tej yam kev mob. Nws lub tank me me steel tau nruab nrog huab cua- tiv thaiv txheej, siab-voltage porcelain bushings, qis-voltage bushings, off-load tap changer, siab nyem, thiab tank-mounted grounding provisions, kom ntseeg tau tias ntev -kev nyab xeeb thiab kev nyab xeeb ntawm lub taub hau. Lub transformer txhawb Ii0 vector pawg configuration thiab yog wired nrog rho polarity, uas dlhos nrog IEEE C57.12.70 davhlau ya nyob twg cim cov qauv rau ib zaug -phase units thiab ua kom yooj yim mus rau tib lub sijhawm ua haujlwm thiab kev sib txuas nrog cov qauv siv hluav taws xob.

Nws ua ke ntawm rugged ncej-mounted tsim, qib siab qis-cov tub ntxhais siv thev naus laus zis, tsim kom muaj qhov sib txawv polarity, ntxiv rau cov rwb thaiv tsev zoo dua thiab luv luv -circuit withstand peev xwm, ua rau nws muaj kev lag luam-xov xwm zoo rau kev faib tawm kawg- mais kev xa hluav taws xob hauv ob lub nroog fringe thiab thaj chaw thaj chaw deb.

02 Kev tsim khoom

2.1 Core

Cov tub ntxhais yog ua los ntawm qib siab -qib, txias- dov, nplej- taw qhia silicon steel nrog cov kauj ruam sib koom ua ke tsim, zoo txo ​​qis hysteresis poob thiab eddy tam sim no poob. Tag nrho cov tub ntxhais yog annealed kom txo qis qhov seem tshuav, ua rau txo qis tsis muaj-load tam sim no thiab tsis muaj-load poob rau kev txhim kho kev ua haujlwm. Lub kaw lus clamping ua kom lub tshuab ruaj khov thaum lub sijhawm thauj mus los thiab ua haujlwm ntev -.

2.2 Cua txias

Ob leeg HV thiab LV windings siv siab -purity oxygen-dawb tooj liab conductors (txhuas xaiv tau) nrog compact winding geometry. Interlayer thiab interturn rwb thaiv tsev siv siab - cov ntawv ntsuas kub los yog Nomex® cov ntaub ntawv, muab luv luv - Circuit Court muaj peev xwm. Tus qauv tsim kom muaj kev faib hluav taws xob tsis sib xws; theem tso tawm ib nrab yog khaws cia qis dua 1/3 ntawm tus qauv txwv. Tapping ntau raws li ± 2 × 2.5% lossis kev cai yuav tsum tau ua.

2.3 Tank

Lub tank yog ua tiav kev tsim kho, welded los ntawm siab - zoo steel daim hlau, thiab raug xau thiab kev ntsuas siab. Qhov saum npoo yog kho nrog cov xim pleev xim rau sab nraum zoov (C5-M qib rau qhov chaw nruj), haum rau kev raug tshav ntuj ntev, los nag, daus, thiab ntsev tsuag. Lub hau npog yog tsim los nrog cov ntaub thaiv npog los nag, thiab cov ces kaum bushing yog optimized rau ncej mounting thiab cable txuas. Radiator fins los yog corrugated phab ntsa yog tsim los rau optimized kub nce nrog ntuj roj ncig (ONAN txias).

2.4 Kev sib dhos zaum kawg

Kev sib dhos zaum kawg yog ua tiav raws li IEEE cov qauv, suav nrog cov tub ntxhais - winding stacking, nqus cov roj txhaj tshuaj, kev kho rwb thaiv tsev thiab cov khoom siv ntxiv. Tag nrho cov qauv yog compact, nrog tsim nyog layout ntawm high-voltage thiab low-voltage bushings thiab kais changer, sib piv cov overhead ncej-mounted installation loj thiab lub zog yuav tsum tau. Lub polarity, vector pawg thiab winding kev sib koom ua ke yog calibrated kom ruaj khov thiab txhim khu kev qha kev ua haujlwm.
