225 KVA Underground Hluav Taws Xob Transformer-13.8 / 0.48 KV|USA 2026

01 General

1.1 Project Description

Thaum lub Plaub Hlis 2026, ib tus neeg Asmeskas cov neeg siv khoom koom nrog hauv kev lag luam hauv av hluav taws xob xa hluav taws xob tau tso cai rau 225 kVA peb-theem underground hluav taws xob hloov hluav taws xob tsim rau lub voj voog- pub cov khoom faib khoom. Lub ncoo mounted underground transformer yog tsim los rau 13.8 kV thawj voltage thiab 480 V theem nrab voltage ua hauj lwm nrog Dyn1 vector pawg configuration, muab ruaj khov peb -theem fais fab faib rau niaj hnub underground hluav taws xob infrastructure.

Txhawm rau ua kom tau raws li cov neeg siv khoom xav tau rau kev siv hluav taws xob, kev nyab xeeb kev ua haujlwm, thiab lub sijhawm ntev - kev ntseeg siab hauv cov chaw xa khoom hauv av, cov hluav taws xob hauv av tau tsim nrog FR3 natural ester insulating kua, peb -theem peb-limb core qauv, thiab DOE 2016 siab- ua haujlwm tau zoo. 5.75% impedance configuration pab tswj qhov voltage stability nyob rau hauv fluctuating coj mus muag loads, thaum high-voltage lightning arresters txhim kho surge tiv thaiv kev ua tau zoo nyob rau hauv underground utility systems.

Qhov no underground pad mounted transformer yog tsim los rau kev lag luam hauv av siv hluav taws xob xws li cov chaw muag khoom hluav taws xob thiab EV charging infrastructure qhov chaw muaj kev nyab xeeb, kev tiv thaiv ib puag ncig, thiab kev ntseeg siab hauv av hluav taws xob yog qhov tseem ceeb.

1.3 Cov duab kos

225kVA peb theem underground hluav taws xob transformer kos duab thiab nameplate

02. Kev tsim khoom & kev teeb tsa

2.1 Peb-Phase Core Design

Cov hluav taws xob hluav taws xob hauv av tau txais peb-theem peb-limb core qauv tsim nrog siab-permeability silicon steel laminations, optimized kom txaus siab rau DOE 2016 efficiency yuav tsum nrog txo tsis muaj -load poob, ruaj khov magnetic kev ua tau zoo, thiab tsis tshua muaj kev khiav hauj lwm suab nrov nyob rau hauv tas li ntawd mus underground kev pab cuam.

2.2 Aluminium Winding

Aluminium windings tau tsim los rau 13.8 kV / 480 V tis daim ntawv thov nrog Dyn1 vector pawg teeb tsa thiab 5.75% impedance, muab kev tswj xyuas qhov hluav taws xob ruaj khov thiab ruaj khov peb - theem kev ua haujlwm.

Lub tshuab hloov pauv tau nruab nrog lub de-energized tap changer (NLTC) featuring ± 2 × 2.5% kais txoj haujlwm rau kev hloov hluav taws xob hluav taws xob raws li kev ua haujlwm sib txawv.

2.3 Tank Kev Tsim Kho

Lub tshuab hloov pauv siv lub kaw lus kaw -mounted tuag- pem hauv ntej tank qauv tsim rau kev lag luam hauv av. Sau nrog FR3 insulating kua, lub tank muab kev ruaj ntseg rwb thaiv tsev kev ua tau zoo thiab txo cov dej noo ingress thaum lub sij hawm ntev - ua haujlwm sab nraum zoov. Tsis tas li ntawd, lub thawv ntim tau tiav nrog hmoov-coated xim dawb (RAL 9003).

2.4 Kev tiv thaiv Surge

Peb qhov kev faib tawm -cov tub ceev xwm xob laim raug teeb tsa rau ntawm qhov siab - qhov hluav taws xob sab los tiv thaiv hluav taws xob hauv av hluav taws xob tiv thaiv kev cuam tshuam dhau los ntawm kev siv hluav taws xob los ntawm xob laim hluav taws xob thiab hloov hluav taws xob uas feem ntau pom hauv cov khoom siv hluav taws xob hauv av.

2.5 Kev sib dhos zaum kawg

Kev sib dhos zaum kawg suav nrog kev ua tiav kev teeb tsa, kev tshuaj xyuas sab hauv, kev kuaj xyuas lub tank sealing, kev tshuaj xyuas cov hlua, thiab kev kuaj lub Hoobkas niaj hnub raws li IEEE C57.12.34-2022 cov cai.

Lub transformer nameplate tau tsim nrog UL cim, thiab tag nrho cov kev ntsuam xyuas hluav taws xob, mechanical, thiab rwb thaiv tsev tau ua tiav ua ntej xa khoom.

03 Kev Xeem

05 Site thiab Summary

Lub tshuab hluav taws xob hauv av no tau tsim kho los muab kev ntseeg siab, lub zog- siv tau, thiab muaj kev nyab xeeb hluav taws xob faib rau cov ntawv siv hluav taws xob niaj hnub hauv av. Nrog nws cov txheej txheem FR3 rwb thaiv tsev, DOE- ua tau raws li kev ua tau zoo, kev tiv thaiv kev tiv thaiv, thiab cov ntaub ntawv ruaj khov-mounted tsim, lub transformer muab kev cia siab rau ntev - lub sij hawm ua tau zoo rau kev lag luam hauv av hluav taws xob cov phiaj xwm hauv Asmeskas.
