1000 KVA Pad Mounted Transformer Chaw tsim tshuaj paus-12.47/0.48 KV|USA 2025

01 General

1.1 Project Background thiab Application

Muab xa mus rau Tebchaws Meskas hauv xyoo 2025, qhov 1000kVA peb theem pad mounted transformer yog ntsia rau hauv lub voj voog hauv av-fed faib qhov chaw ua haujlwm tsis tu ncua, hloov nrawm, thiab ntev- lub sijhawm ruaj khov yuav tsum nyob rau hauv cov xwm txheej tiag tiag, tsis yog ntawm daim ntawv xwb.

Nyob rau hauv hom network no, lub ncoo mounted transformer yog tsis kho raws li ib tug yooj yim conversion unit; nws coj tus cwj pwm zoo li lub qhov hluav taws xob ruaj khov nyob rau hauv daim phiaj sib faib, qhov chaw thauj khoom hloov pauv, qhov tsis raug, thiab qhov hloov pauv ntawm qhov hluav taws xob tag nrho dhau los thiab yuav tsum tau tswj kom zoo.

Rated ntawm 12.47kV txog 0.48kV, lub ncoo mounted transformer phim tus qauv North American nruab nrab - rau - low voltage system, feem ntau yog siv nyob rau hauv kev lag luam, lub teeb muaj, thiab infrastructure daim ntawv thov nrog sib xyaw thiab dynamic load profiles.

1.2 Voltage Configuration thiab Vector Group (YNd1)

Qhov no1000kVA pad mounted transformersiv 12.47kV grounded wye thawj thiab 0.48kV delta theem nrab, YNd1 vector pawg, xaiv los tswj kev coj tus cwj pwm hauv av, kev sib haum xeeb, thiab kev thauj khoom tsis txaus hauv cov khoom siv ua haujlwm.

Lub hauv paus wye sab txhim kho qhov system siv kev ruaj ntseg thiab kev ua txhaum cai, thaum lub delta winding pab txo qis triplen harmonics thiab txwv kev cuam tshuam kev nthuav tawm, tshwj xeeb tshaj yog thaum lub ncoo mounted transformer muab cov khoom tsis sib xws xws li VFDs, UPS systems, lossis EV charging stations.

1.3 Impedance Tsim (5.75%)

Nrog 5.75% impedance, lub ncoo mounted transformer tshuav luv luv -circuit tam sim no txwv, voltage tswj, thiab tiv thaiv kev sib koom tes.

Nws pab tswj kev ua txhaum theem, txhawb kev sib koom ua ke ntawm kev sib koom ua ke, thiab tswj xyuas tus cwj pwm ruaj khov thaum lub sij hawm thauj khoom sib txawv, kom ntseeg tau tias kev ua haujlwm ruaj khov nyob rau hauv ob qho tib si ib txwm muaj thiab ntu ntu.

1.5 Cov duab kos

1000kVA peb theem ncoo mounted transformer kos duab thiab nameplate

02. Kev tsim qauv, rwb thaiv tsev, ua raws thiab kev tiv thaiv

2.1 Distribution System Design

Qhov no 1000kVA peb theem ncoo mounted transformer txais ib lub voj pub thiab tuag pem hauv ntej qauv, ua kom muaj kev nyab xeeb kev ua haujlwm thiab hloov hluav taws xob txuas ntxiv hauv North American underground systems.

Nyob rau hauv cov khoom siv hluav taws xob thiab kev lag luam, cov ntaub ntawv mounted transformer configuration yog dav siv nyob rau hauv ntev -lub sij hawm stability thiab kev nyab xeeb teb yuav tsum tau.

2.2 Rwb thaiv tsev Performance (FR3 Roj)

Lub ncoo mounted transformer no siv FR3 natural ester kua, txhim kho hluav taws kev nyab xeeb kev ua tau zoo, kev ua raws li ib puag ncig, thiab ntev - lub sij hawm rwb thaiv tsev stability.

Thaum lub sij hawm tsim khoom, lub tshuab nqus tsev ziab, roj filling, thiab sealing txheej txheem yog nruj me ntsis tswj xyuas kom ruaj khov dielectric kev ua tau zoo ntawm lub ncoo mounted transformer nyob rau hauv tiag tiag kev khiav hauj lwm tej yam kev mob.

2.3 Kev ua raws cai thiab kev tiv thaiv

Lub ncoo mounted transformer ua raws li DOE kev ua tau zoo thiab IEEE C57.12.34 cov qauv, ua kom muaj kev sib raug zoo nrog North American daim phiaj thiab kev lees txais kev siv hluav taws xob.

UL / cUL kev ua raws li kev txhawb nqa thiab kev sib koom ua ke ntawm kev sib koom ua ke feem ntau yog ua ke los txhim kho kev ua haujlwm kev ntseeg siab thiab kev tiv thaiv kev ua haujlwm.

03 Kev tsim khoom tseem ceeb

3.1 Core thiab Winding

High-qib silicon steel yog siv rau cov tub ntxhais los txo qhov poob, thaum aluminium windings muab qhov sib npaug ntawm cov nqi ua haujlwm thiab kev ua haujlwm thermal.

Txhua lub ncoo mounted transformer yog tsim los nrog kev tswj cov txheej txheem los xyuas kom meej kev ua haujlwm ruaj khov nyob rau hauv kev thauj khoom tas mus li thiab luv luv - cov xwm txheej hauv Circuit Court.

3.2 Tank Tsim

Lub tank ntim nrog RAL 9003 hmoov txheej ua kom muaj kev tiv thaiv corrosion thiab ntev -lub sij hawm sab nraum zoov.

Kev sib khi nruj thiab cov txheej txheem kho saum npoo yog siv los xyuas kom muaj kev ntseeg tau ntawm lub ncoo mounted transformer nyob rau hauv ib puag ncig hnyav.

04 Ntim thiab thauj

05 Site thiab Summary

Qhov no 1000kVA peb theem ncoo mounted transformer yog tsim los txhim khu kev qha kev lag luam nyob rau hauv North American tis systems, combining kev nyab xeeb, efficiency, thiab ib puag ncig kev ua tau zoo.

Los ntawm kev tsim mus rau kev tsim khoom, lub hom phiaj yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau yog qhov ua kom pom tseeb ntawm kev ua kom txhua lub pad mounted transformer tuaj yeem ua haujlwm ruaj khov hauv cov kab sib chaws tiag tiag nrog kev ua raws thiab kev ua haujlwm ntev ntev.
