01 General
1.1 Project Description
Qhov kev txiav txim los ntawm peb cov neeg siv khoom hauv Guyana 2024, lub tuam txhab kev pabcuam hluav taws xob engineering, suav nrog cov khoom siv hluav taws xob uas muaj peev xwm ntawm 25kVA, 50kVA, 75kVA, 100kVA, thiab 167kVA. 50kVA Zoo tagnrho rau nruab nrab- thaj chaw nyob lossis kev lag luam me.
Lub transformer tau ua raws li IEEE & ANSI C57.12.00 tus qauv. Ua haujlwm ntawm thawj qhov hluav taws xob ntawm 13,800V, nqis mus rau 120 / 240V ntawm ob sab, nrog rau zaus ntawm 60Hz thiab tooj liab windings. Lub impedance yog 2%, txo qis voltage poob nyob rau hauv load.
Nruab nrog ONAN cua txias system thiab NLTC (Tsis Muaj Load Tap Changer), nws muaj 10% tapping ntau yam (± 2.5% ib tus kais), stabilizing theem nrab voltage txawm tias thawj qhov kev hloov pauv. Qhov tsis muaj -load poob yog 160W, thiab ntawm -load poob yog 512W, optimizing zog siv. Lub transformer nta kev rho tawm polarity thiab ib pawg vector ntawm Ii0, txhais nws cov theem kev sib raug zoo.
Raws li ib tug ua lag luam ntawm transformers, peb muab qhov zoo meejtransformer dawsrau koj cov kev xav tau ntawm hluav taws xob.

02 Kev tsim khoom
2.1 Core
Qhov zoo ntawm cov txheej txheem ntawm lub qhov txhab tseem ceeb yog tias nws tso cai rau cov khoom siv ferromagnetic kom siv tag nrho nws cov khoom siv hluav taws xob zoo, txo cov tub ntxhais poob coefficient. Cov ceg tseem ceeb thiab tus ncej ntoo khaub lig- ntu ntawm ib qho - theem lub qhov txhab tseem ceeb yog ob qho tib si duab plaub thiab txuas ntxiv qhov txhab nrog cov hlau nplaum hlau nplaum, txo qis tsis muaj -load poob, tsis muaj-load tam sim no, thiab lub suab nrov transformer.
2.2 Cua txias
Peb transformer windings siv siab -purity enameled round tooj liab hlau, featuring zoo heev hluav taws xob conductivity thiab compact rwb thaiv tsev. Lub enamel txheej muab cov rwb thaiv tsev zoo ib yam thiab txhim khu kev qha dielectric zog. Txais yuav qhov zoo tshaj plaws coil qauv ntawm cov ntawv ci winding rau qis -voltage coils thiab xaim winding rau siab -voltage coils, kom ntseeg tau tias kev ua haujlwm zoo, kev cia siab, thiab kev ua haujlwm thermal.
2.3 Tank
Lub tank me me nrog cov welded lifting lugs thiab hanger brackets rau ncaj qha - mus rau - ncej mounting. KVA ntsuas ntawm phab ntsa tank. Cov txheej tiv thaiv yog siv rau cov tso tsheb hlau luam kom txo tau qhov corrosion. Txhawm rau ua kom muaj kev nyab xeeb ntawm cov hluav taws xob hloov hluav taws xob no txawm tias raug huab cua hnyav thiab lawv qhov chaw nyob deb, kev ntseeg tau tsim rau hauv lawv cov specifications.
2.4 Kev sib dhos zaum kawg
1. Winding Assembly:Xaub lub HV / LV windings mus rau hauv cov tub ntxhais laminated, kom ntseeg tau tias kev sib raug zoo thiab kev ruaj ntseg ntawm rwb thaiv tsev.
2. Kev sib txuas hluav taws xob:Txuas winding coj mus rau kais hloov pauv, bushings, thiab lwm yam khoom, ces ruaj ntseg thiab insulate cov pob qij txha.
3. Core-Coil ziab:Muab cov khoom sib dhos ua ke (core + windings) rau hauv qhov cub kom qhuav rau lub tshuab nqus tsev kom tshem tawm cov dej noo.
4. Tank Installation:Nqa cov khoom ua haujlwm qhuav rau hauv lub tank, tso nws kom ruaj ntseg, thiab xyuas kom muaj kev rwb thaiv tsev los ntawm cov phab ntsa tank.
5. Accessory Mounting:Txhim kho bushings, siab nyem valve thiab lwm yam khoom siv, tom qab ntawd xyuas seb cov dej xau.
6. Roj Sau & Teeb:Lub tshuab nqus tsev- sau nrog cov roj insulating, degas, thiab tso cai rau kev daws teeb meem ua ntej kuaj cov roj qib thiab lub zog dielectric.
