Qhov hluav taws xob: 7.97 / 13.8Y-0.277kV
Feature: Amorphous core
Ua tau zoo, txhim khu kev qha, thiab eco-tus phooj ywg-powering koj lub network faib nrog Scotech's 50 kVA ncej-mounted transformer
01 General
1.1 Project Description
Qhov no 50 kVA ib qho -theem transformer ntawm lub hwj chim kab yogtsim los ntawm Scotechthiab exported rau Canada. Lub transformer ua tau raws li IEEE C57.12.20 cov qauv, ua kom ntseeg tau kev ua tau zoo rau cov chaw nyob thiab lub teeb ua lag luam.
Qhov kev txiav txim no suav nrog 20 units ntawm ib qho -theem ncej-mounted transformers, ntawm cov 5 units yog ntawm no 50 kVA qauv. Txhua lub tshuab hloov pauv yog tsim los rau thawj qhov hluav taws xob ntawm 7.97 / 13.8Y kV thiab qhov hluav taws xob thib ob ntawm 277 V, muaj ob lub siab -voltage bushings thiab ob qhov qis{10}}voltage bushings. Lub transformer yog nruab nrog tsis muaj -load tap changer (NLTC) nrog ± 2 × 2.5%.
Lub 50 kVA transformer ntawm lub hwj chim kab siv lub amorphous alloy core, txo tsis muaj -load poob rau 0.043 kW thiab load poob rau 0.5 kW. Nws yog lub zog-txuag thiab tus phooj ywg ib puag ncig, txo cov nqi hluav taws xob.
Lub transformer hnyav 327 kg, nrog rau 81 kg ntawm insulating roj. Cov roj pab ua kom txias thiab rwb thaiv tsev. Nws loj yog 645 × 715 × 1115 mm. Tus qauv me me thiab sib npaug sib haum zoo rau ntawm tus ncej- txuas fais fab. Tus thawj coj surge arrester tso cai yooj yim kev koom ua ke ntawm cov cuab yeej tiv thaiv, txhim kho kev ntseeg tau thiab kev nyab xeeb.
Tsim nrog aluminium windings, additive polarity, thiab ONAN ntuj cua txias, qhov transformer ntawm lub hwj chim kab yog compact, npaum, thiab txhim khu kev qha. Aluminium kev tsim kho thiab kev tsim qauv ntse muab cov kev daws teeb meem hloov pauv rau niaj hnub siv hluav taws xob faib hluav taws xob, ua kom lub zog ua haujlwm tau zoo thiab ua haujlwm tau zoo.

02 Kev tsim khoom
2.1 Core
Lub 50kVA transformer ntawm lub hwj chim kab siv lub amorphous hlau core, ib qho isotropic mos magnetic khoom nrog siab resistivity, zoo heev txo eddy tam sim no poob. Piv nrog rau txias- dov silicon steel, nws txo cov tub ntxhais poob los ntawm 70-80%, ua tiav qhov tsis muaj-load poob ntawm 0.043 kW thiab load poob ntawm 0.5 kW. Nws nyias 0.03 hli ribbons yooj yim tsim, txhim kho kev ua haujlwm, thiab muab lub zog -txuag, eco- cov tshuaj zoo.
2.2 Cua txias
Optimized coil design nta ntawv ci-mob tsawg-voltage coils thiab xaim-mob siab-voltage coils. Cov neeg siv khoom tuaj yeem xaiv aluminium rau LV coil, txo tus nqi thiab qhov hnyav thaum tswj kev ntseeg tau thiab kev ua neej zoo ib yam li tooj liab. Polarity yog additive thiab transformer ua raws li vector pawg Ii6, muab kev sib raug zoo theem thiab txhim khu kev qha.
2.3 Tank
Tsim los rau ncej mounting, lub tank transformer no tiav nyob rau hauv lub teeb grey thiab tsim los ntawm siab -zoo low- carbon steel siv cov txheej txheem kos duab los tsim ib lub cylindrical qauv. Lub tank lub cev siv cov cuab yeej sib khi, nrog lub hau thiab hauv qab tsim los ntawm cov ntawv hlau stamping, txo qhov hnyav thaum ua kom muaj zog ntawm cov qauv.
