01 General
1.1 Project Description
1500 kVA chav tsev substation transformer raug xa mus rau Tebchaws Meskas hauv xyoo 2025. Lub zog ntsuas ntawm lub transformer yog 1500 kVA nrog KNAN txias. Qhov siab voltage yog 5D kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov tsawg voltage yog 0.48Y / 0.277 kV, lawv tsim ib pawg vector ntawm Dyn1.
Cov chaw nres tsheb hluav taws xob yog cov khoom siv hluav taws xob sib txuas sib txuas uas sib txuas ua ke thawj qhov hloov pauv, peb lub -theem fais fab transformer, thiab cov khoom siv hluav taws xob thib ob rau hauv ib qho, kaw- sib txuas ua ke. Nws yog tsim los txo cov nqi hluav taws xob faib hluav taws xob mus rau qib uas haum rau hauv - cog lossis kev lag luam hauv tsev faib khoom, thiab tsim nyog rau kev teeb tsa sab hauv tsev thiab sab nraum zoov. Nrog rau nws nyob ze-coupled tsim, lub transformer tuaj yeem muab tso rau ze ntawm qhov chaw thauj khoom, txo qhov ntev ntawm cable thiab tsheb npav, uas ua rau txo qis kab poob thiab raug cuam tshuam thaum txhim kho kev tswj hluav taws xob thiab kev pabcuam txuas ntxiv. Piv nrog rau cov qauv substation ua ke, nws cov hneev taw me me txuag tau ntau qhov chaw teeb tsa, txo rau ntawm - qhov chaw tsim kho thiab cov nqi tsheb thauj mus los, thiab txo qis ntev - cov nqi kho mob los ntawm cov khoom siv yooj yim. Chav tsev substation transformer ua raws li ANSI, IEEE, thiab NEMA cov qauv, ua kom tiav kev sib koom ua ke ntawm hluav taws xob thiab tshuab. Raws li ib qho kev xaiv, lub transformer tuaj yeem sau nrog FR3 ™ natural ester kua- tauj dua tshiab, zaub- roj-raws li dielectric nrog rau qhov hluav taws kub siab thiab ib puag ncig zoo heev -thaum cov roj ntxhia roj tseem muaj rau cov ntawv thov nrog cov qauv yuav tsum tau ua. Nrog nws cov kev ntseeg siab, efficiency, thiab hloov tau yooj yim configuration, lubchav tsev substation transformeryog siv dav hauv cov chaw tsim khoom, cov tsev lag luam, cov chaw siv hluav taws xob, thiab cov kev sib txuas lus tseem ceeb uas qhov chaw, kev nyab xeeb, thiab kev ua haujlwm tseem ceeb.
