01 General

1.1 Project Description

Muab xa mus rau Tebchaws Meskas xyoo 2024, qhov no 2000 kVA peb-theem ncoo-mounted tis transformers yog tsim los ua raws li IEEE Std C57.12.34-2022 thiab ua raws li DOE 2016 cov cai tswj kev siv hluav taws xob. Lub transformer nta 4.16 kV thawj thiab 480GrdY / 277 V theem nrab nrog Dyn1 vector pawg. Nws siv tooj liab windings rau txhim khu kev qha kev ua tau zoo thiab kav ntev, KNAN cua txias kom zoo cua sov dissipation, thiab FR3 natural ester kua rau txhim kho hluav taws kev ruaj ntseg thiab ib puag ncig sustainability.

Tus qauv tsim muaj lub voj voog pub thiab tuag- nkag rau pem hauv ntej, txhawb nqa ob qho tib si kev nyab xeeb thiab kev txhim kho yooj yim. Nws kuj suav nrog qhov tsis muaj -load kais hloov pauv nrog ± 2 × 2.5% kev tswj qhov hluav taws xob ntau. Nrog rau qhov impedance ntawm 5.75%, tsis muaj-load poob ntawm 1.350 kW, thiab load poob ntawm 16.000 kW, lub transformer no xa cov kev hloov pauv hluav taws xob zoo thiab ruaj khov rau nruab nrab -voltage distribution systems.

Tsim los ua kom tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob niaj hnub no thiab cov chaw tsim khoom lag luam, peb lub ncoo -mounted tis transformers muab lub compact, low{1}}profile design yam tsis muaj kev cuam tshuam txog kev nyab xeeb lossis ntev - lub sij hawm durability.
