50 Kva Transformer Ncej Mount-13.8/0.12*0.24 KV|USA 2025

01 General

1.1 Project Description

Lub 50 kVA ib qho -theem ncej- mounted transformer muaj 13.8 kV thawj thiab 120/240 V theem nrab. Tsim los rau IEEE C57.12.20 rau overhead faib transformers. Nws haum rau 13.8 kV peb-theem, peb- xaim xaim xaim hauv North America. Cov50kva ncej mount transformernta ONAN ntuj roj txias nrog cov ntxhia roj rwb thaiv tsev. Nrog rau kev tsom mus rau kev ua tau zoo thiab qhov chaw optimization, Scotech siv ob qho tib si txhuas thiab tooj liab winding. Lub polarity yog rho tawm, thiab pawg vector yog Ii0, kom ntseeg tau tias cov theem ua tiav hauv lub network faib. Kev ua haujlwm tseem ceeb suav nrog tsis muaj-load poob ntawm 0.14 kW, load poob ntawm 0.527 kW, tag nrho poob ntawm 0.667 kW, thiab tag nrho -load efficiency ntawm 98.97%. Impedance yog 2.86%, nyob rau hauv ib txwm faib transformer ntau yam. Tsis tas li ntawd, lub tshuab hloov pauv tau nruab nrog tsis muaj -load kais hloov pauv (NLTC) uas tso cai rau siab - qhov hloov pauv hloov hluav taws xob los ntawm 14, 400 V txog 12, 540 V kom haum rau qhov hloov pauv voltage hauv lub network.

02 Kev tsim khoom

2.1 Core

Siv cov nplej- taw qhia silicon steel, lub qhov txhab lub qhov txhab muab kev ua haujlwm zoo sib nqus los ntawm kev txo qis kev cuam tshuam hauv txoj kev flux. Tus tsim zam kev sib nqus saturation, ua kom ruaj khov ua haujlwm raws li kev hloov pauv ntawm kev thauj khoom. Piv nrog rau cov txheej txheem txheej txheem ib txwm muaj, cov qauv qhov txhab txo qis tsis muaj-load poob thiab tsis muaj-load tam sim no, thaum tseem txo qis kev vibration thiab suab nrov. Cov txiaj ntsig zoo no ua rau lub qhov txhab muaj zog heev - ua haujlwm tau zoo thiab txhim khu kev qha hauv kev faib khoom.

2.2 Cua txias

Lub high voltage winding txais concentric tsim nrog electrolytic tooj liab hlau ntawm 99.9% purity, enamel insulated, kom ntseeg tau conductivity tsis tsawg tshaj li 100% IACS. Thermal rwb thaiv tsev withstands mus txog 105 degree. LV winding siv aluminium ntawv ci, uas txo qis eddy tam sim no poob, ua kom muaj zog txhua yam kev ncaj ncees, thiab ua tau raws li cov khoom siv hluav taws xob.

 

2.3 Tank

Lub tank transformer yog lub kaw lus cylindrical qauv ua los ntawm cov hlau me me nrog txheej txheej hauv RAL7035 xim. Nws yog tsim los tsis muaj kev soj ntsuam los yog tu lub qhov kom ntseeg tau tias muaj kev ncaj ncees. Ib lub hau domed tshem tau yog siv rau kev nkag. Mounting brackets yog ua los ntawm cov hlau nrog qhov tsawg kawg nkaus thickness ntawm 3.4 hli. Qhov kawg yog khoov thiab welded rau lub tank lub cev. Qhov no ua rau cov qauv muaj zog thiab ruaj khov.

 

2.4 Kev sib dhos zaum kawg

1. Winding Assembly:Xaub lub HV / LV windings mus rau hauv cov tub ntxhais laminated, kom ntseeg tau tias kev sib raug zoo thiab kev ruaj ntseg ntawm rwb thaiv tsev.
2. Kev sib txuas hluav taws xob:Txuas winding coj mus rau kais hloov pauv, bushings, thiab lwm yam khoom, ces ruaj ntseg thiab insulate cov pob qij txha.
3. Core-Coil ziab:Muab cov khoom sib dhos ua ke (core + windings) rau hauv qhov cub kom qhuav rau lub tshuab nqus tsev kom tshem tawm cov dej noo.
4. Tank Installation:Nqa cov khoom ua haujlwm qhuav rau hauv lub tank, tso nws kom ruaj ntseg, thiab xyuas kom muaj kev rwb thaiv tsev los ntawm cov phab ntsa tank.
5. Accessory Mounting:Txhim kho bushings, siab nyem valve thiab lwm yam khoom siv, tom qab ntawd xyuas seb cov dej xau.
6. Roj Sau & Teeb:Lub tshuab nqus tsev- sau nrog cov roj insulating, degas, thiab tso cai rau kev daws teeb meem ua ntej kuaj cov roj qib thiab lub zog dielectric.
