3000 kVA Residential Transformer Box-23.9/11.95*13.8 kV|Jamaica 2025

01 General

1.1 Project Background

A 3000 kVA peb theem ncoo mounted transformer tau xa mus rau Asmeskas xyoo 2025. Lub zog ntsuas ntawm lub transformer yog 3000 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 23.9GrdY / 13.8 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 11.95GrdY / 6.9 * 13.8D kV, lawv tsim ib pawg vector ntawm YNyn0 / YNd11.

Peb -theem ncoo-mounted transformers feem ntau yog tsim los kom compact kom haum rau qhov chaw txwv hauv nroog lossis chaw lag luam. Cov khoom siv hluav taws xob hloov pauv, hloov khoom siv, thiab lwm yam khoom siv yog nyob rau hauv ib lub tsev hlau muaj zog, tso cai rau kev teeb tsa ncaj qha rau hauv av. Cov qauv tsim muaj kev hloov pauv zoo ib puag ncig, tso cai rau siv ntau yam kev nyab xeeb thiab thaj chaw, suav nrog cov av noo thiab qhov siab siab. Piv nrog rau cov khoom siv hluav taws xob ib txwm muaj, ncoo- cov tshuab hloov pauv tau yooj yim dua rau nruab, thiab kev saib xyuas thiab kev tshuaj xyuas ib txwm muaj ncaj qha, ua rau nws yooj yim los hloov cov khoom puas sai sai. Lawv feem ntau ntiav cov roj- rau qhov txias txias, qhov twg cov roj hloov pauv tau ua tiav cov cua sov. Pad-mounted transformers yog tsim nrog lub zog ntsuas txij li kwv yees li 15 kVA txog 5000 kVA. Lawv feem ntau muaj cov fuses sib xyaw thiab cov keyboards rau kev txhim kho kev nyab xeeb thiab kev ua haujlwm. Cov kab hluav taws xob tseem ceeb tuaj yeem txuas nrog siv lub luj tshib txuas, uas tuaj yeem ua haujlwm tau thaum lub tshuab hloov hluav taws xob muaj zog siv lub pas kub. Qhov kev teeb tsa no muab kev yooj yim hauv kev kho thiab tu, tso cai rau kev ua haujlwm yooj yim thiab ua haujlwm tau zoo.

02 Kev tsim khoom

2.1 Core

Lub tsib-limb core tsim tau zoo txo ​​eddy tam sim no poob thiab hysteresis poob, txhim kho transformer efficiency. Lub optimized magnetic circuit tsim ua rau txo qis electromagnetic suab nrov thaum ua haujlwm. Qhov sib npaug ntawm peb-theem sib nqus Circuit Court thiab lub auxiliary limb's magnetic path txhim khu lub transformer lub peev xwm los lis luv luv-circuit tej yam kev mob.

2.2 Cua txias

Transformer Winding yog lub voj kaw uas tsim los ntawm tus neeg xyuas pib tooj liab, uas tau muab faib ua qhov siab voltage (HV) winding thiab tsis tshua muaj hluav taws xob (LV) winding raws li kev ua haujlwm ntawm transformer. Lawv ua ke nrog ib leeg los ntawm electromagnetic induction kom paub qhov hloov dua siab tshiab ntawm hluav taws xob hluav taws xob ntawm qhov sib txawv voltage. pad mounted transformer keyboards ntawm YNyn0 thiab YNd11 kev sib txuas hom, tso cai rau lub transformer ua hauj lwm nyob rau hauv txawv daim ntawv thov scenarios, xws li lub hwj chim mov systems yuav tsum tau nruab nrab cov ntsiab lus (YNyn0) los yog industrial load scenarios xav tau daim duab peb sab windings los tiv thaiv tsis txaus (YNd11).

2.3 Tank

Siv siab- zoo carbon steel hlau daim hlau nrog lub thickness ntawm 3-6 hli, kom ntseeg tau siab zog thiab corrosion kuj. Txiav cov hlau phaj siv laser lossis shearing tshuab kom paub meej qhov ntev, Ua haujlwm CO₂ shielded vuam lossis TIG vuam, tsom rau ob npaug - sab vuam rau cov seams tseem ceeb. Tom qab ntxuav thiab xuab zeb blasting, siv ntau- txheej txheej (anti- xeb primer + corrosion-resistant topcoat) kom muaj kev tiv thaiv corrosion thiab zoo nkauj. Ua cov kev ntsuam xyuas xau (piv txwv li, nitrogen pressurization) thiab kev ntsuam xyuas lub zog kom ntseeg tau tias tsis muaj qhov xau thiab txaus rigidity.

2.4 Pentahead Bolt

Peb muab tag nrho raws li captive pentahead bolt tsim nrog rau kev ruaj ntseg latch. Peb lub qhov rooj tiv thaiv kev kaw qhov rooj tshwj tsis yog lub pentahead bolt yog nruj nruj. Tag nrho cov txheej txheem kaw yog recessed rau ib tug tamper -cov qauv resistant. Lub ntsia liaj qhov rooj tseem raug ntes kom tsis txhob raug tshem tawm lossis xov puas thaum lub sijhawm ua haujlwm ntawm lub qhov rooj, txawm tias raug kaw, thiab ua tau raws li IEEE C57.12.28/34 cov cai.
