01 General
1.1 Project Description
Peb 25 kVA ib qho -theem ncej- mounted transformers tau muab rau Canadian tus neeg siv khoom los ntawm Scotech hauv 2024 raws li ib feem ntawm cuaj-unit order. Ua tiav raws li CSA C2.2-06 tus qauv. Rated rau thawj qhov hluav taws xob ntawm 25 kV thiab qhov hluav taws xob thib ob ntawm 0.347 kV, muab tag nrho lub peev xwm ntawm 25 kVA nyob rau hauv qhov nruam load. Nws siv ONAN natural oil cooling, ntxhia roj raws li qhov nruab nrab insulating, additive polarity, thiab vector pawg Ii6.
Qhov no transformer nta aluminium windings, txo qhov hnyav thiab nqi, ua rau kev teeb tsa thiab kev thauj mus los yooj yim dua. Nws 2.8% impedance pab sib npaug luv luv - Circuit Court tam sim no thiab kev tswj hluav taws xob hauv cov tshuab xa khoom, ua kom yooj yim rau kev tiv thaiv kev teeb tsa. Nws tau nruab nrog NLTC (Tsis yog-Load Tap Changer) nrog 2.5% kauj ruam, tso cai rau cov zis hluav taws xob hloov pauv thaum lub sijhawm ua haujlwm kom ruaj khov. Nws kuj muaj 33 kV polymer xob laim ntes thiab dual siab -voltage bushings kom zoo xob laim thiab tiv thaiv overvoltage.
Qhov kev teeb tsa hluav taws xob no muaj nyob hauv North American thiab Canadian tis systems. Cov qauv no ua haujlwm rau cov zej zog nyob deb nroog, thaj chaw nyob, thiab cov lag luam me uas ruaj khov ib leeg -theem fais fab yog qhov tseem ceeb. 25 kV thawj qhov kev sib txuas ua rau nws muaj kev xaiv zoo rau feeder lossis voj tshuab nyob rau hauv ib puag ncig sab nraum zoov uas muaj kev ua haujlwm siab dua. Txawm hais tias siv nyob rau hauv cov kab tseem ceeb nyob deb nroog lossis qhov kawg ntawm lub nplhaib network, qhov hloov pauv no muab kev ua haujlwm ruaj khov thiab txhim khu kev qha.

02 Kev tsim khoom
2.1 Core
Cov tub ntxhais transformer yog ib qho tseem ceeb ntawm kev tsim cov hlau nplaum hluav taws xob thiab ua kom lub zog hloov pauv ntawm thawj thiab theem nrab windings. Nws siv siab - zoo lis- taw qhia silicon steel laminations stacked thiab insulated kom txo qis eddy tam sim no poob. Cov tseem ceeb nta ib tug tub ntxhais- hom tsim nrog cov kab plaub hau, optimized rau siab tshaj plaws sib nqus flux thiab high efficiency nyob rau hauv kev lag luam tas mus li.
2.2 Cua txias
Aluminium windings yog tsim nyob rau hauv kev tswj nruj ntawm kev taw qhia, polarity, thiab nro. Lub LV kauj yog qhov txhab ua ntej, ua raws li HV kauj, nrog txheej rwb thaiv tsev compactly thov thiab tsis muaj wrinkles. Hloov qhov tseeb yog nyob rau hauv ± 0.3%. Radial roj ducts Ntau dua lossis sib npaug li 3 hli thiab ruaj khov ua kom txias txias thiab lub zog txhua yam, tiv thaiv deformation thaum lub sijhawm ua haujlwm.
2.3 Tank
Lub tank roj tau tsim kom ua tau raws li cov qauv nruj nreem kaw. Nws muaj cov flanges muaj zog thiab kev txhawb nqa, tuaj yeem nqa qhov hnyav thiab kev co, thiab nta ruaj ntseg mounting qhov. Cov khoom siv tank tiv taus qhov kub thiab txias. Gaskets kom tsis txhob muaj roj. Qhov saum npoo yog kho tiv thaiv corrosion. Sab saum toj muab qhov chaw txaus rau kev tshem tawm yooj yim thiab hloov cov neeg ntes yam tsis muaj kev cuam tshuam kev sib khi.
2.4 Kev sib dhos zaum kawg
Core thiab Winding Assembly
Nruab qhov siab -voltage thiab low-voltage windings mus rau hauv lub hauv paus, kom ntseeg tau tias rwb thaiv tsev thiab concentricity.
Lub cev Installation
Muab cov tub ntxhais thiab winding sib dhos rau hauv lub tank roj.
Txhim kho cov hlau lead thiab insulating bushings, xyuas kom zoo sealing.
Filling Transformer Roj
Txhaj cov roj hloov pauv hloov, kom nws huv si thiab tsis muaj impurities.
Nruab Cov Khoom Siv Sab Nraud
Txuas cov kev nyab xeeb li qub, roj qib ntsuas, thiab kev sib txuas ntawm lub davhlau ya nyob twg.
