2000 kVA Pad Mounted Transformer-24/0.48 kV|USA 2024

 

 

01 General

1.1 Project Description

Qhov no yog 2000 kVAncoo -mounted transformerua tau raws li US cov qauv tshiab, suav nrog IEEE C57.12.34-2022 thiab DOE 2016 kev ua haujlwm zoo. Nws nqis nqis thawj qhov hluav taws xob hluav taws xob los ntawm 24 kV mus rau qhov tso tawm thib ob ntawm 480GrdY / 277 V.

Featuring tooj liab windings thiab ib pawg Dyn1 vector, nws KNAN txias ua kom muaj kev ua haujlwm zoo. Kev txhim kho ib puag ncig thiab kev nyab xeeb tseem ceeb los ntawm kev siv cov kua dej FR3 - txhim kho cov ntaub ntawv pov thawj lub tsev ntsuab thaum txo kev pheej hmoo hluav taws, ua rau nws zoo tagnrho rau kev tsim kho vaj tse thiab cov chaw hauv nroog loj.

Nrog lub voj pub ua haujlwm, lub tshuab hloov pauv tau yooj yim rau hauv lub nplhaib- hom kev faib khoom, txhim kho kev ntseeg tau thiab tso cai rau kev saib xyuas niaj hnub yam tsis muaj kev cuam tshuam. Cov tuag-pem hauv ntej tsim txhim kho tus neeg teb xov tooj kev nyab xeeb.

Feem ntau siv rau hauv hluav taws xob faib hluav taws xob, qhov hloov pauv no nce qib siab -voltage input rau kev koom ua ke nrog kev tswj hwm hluav taws xob thiab cov khoom siv hluav taws xob hauv av.
