50kva Ncej Mounted Transformer-7.2/0.12*0.24 KV|Canada 2025

01 General

1.1 Project Description

Qhov no 50 kVA ib qho -theem ncej-mounted transformer muab lub zog muaj kev nyab xeeb thiab txhim khu kev qha rau cov tsev thiab cov lag luam me. Nws yog mounted rau ntawm qhov hluav taws xob ncej thiab nqis nqis siab -voltage hluav taws xob los ntawm lub network faib (12,470 GRDY / 7,200 V) rau tus qauv 120/240 V tso zis rau North American 60 Hz systems.

Lub transformer muaj ib tug laminated steel core uas zoo hloov lub zog ntawm cov thawj thiab theem nrab windings. Cov windings yog ua los ntawm cov qib siab - zoo aluminium thiab muaj cov rwb thaiv tsev tag nrho los daws cov teeb meem hluav taws xob. Chav tsev ua tiav kev ua haujlwm siab (Ntau dua lossis sib npaug rau 99.04%) uas tsis muaj -load poob ntawm 130 W thiab thauj khoom poob ntawm 492 W, thiab nta 2.15% impedance (± 10%) rau kev tswj qhov hluav taws xob zoo sib xws hauv kev thauj khoom. Tsis yog-Load Tap Changer (NLTC) nrog ± 2 × 2.5% kais ntau tso cai rau kev hloov kho qhov hluav taws xob zoo. Ib qho kev sib koom ua ke Internal Fault Detector (IFD) saib xyuas lub transformer rau cov teeb meem sab hauv. A 9 kV siab -voltage arrester tiv thaiv surges. Lub transformer siv ONAN cua txias thiab ntxhia roj rwb thaiv tsev kom ntseeg tau ntev -lub sij hawm sab nraum zoov.

Lub tshuab hluav taws xob no zoo tagnrho rau cov neeg nyob ib puag ncig, ua liaj ua teb, thiab cov chaw lag luam me. Nws ua haujlwm zoo rau cov kev faib tawm nyob deb nroog thiab suburban, txuas txuas ntxiv, thiab kev teeb tsa hluav taws xob ib ntus. Nws lub tank kaw thiab tsim kom muaj zog ua rau nws ntseeg tau nyob rau hauv qhov hnyav sab nraum zoov xws li daus, nag, thiab kub heev.

02 Kev tsim khoom

2.1 Core

Hauv ncej-mounted transformers, cov tub ntxhais kuj tseem tsim kom muaj kev sib haum xeeb thiab kev co- tiv taus kom nws tuaj yeem zaum ntawm cov ncej hluav taws xob. Nws sawv ntsug rau cua, dej khov, thiab lwm yam sab nraum zoov, thaum ua kom tsis muaj - thauj khoom poob qis - uas yog qhov tseem ceeb rau cov kab ntev ntev pub rau cov tsev thiab cov lag luam me.

2.2 Cua txias

Peb cov coils yog tsim los ntawm cov neeg paub dhau los uas ua raws cov txheej txheem meej. Cov neeg ua haujlwm txheej txheej ntawv nruj nruj rau LV coils thiab cua tooj liab sib npaug rau HV coils. Cov thawj coj saib xyuas cov kauj ruam thiab kos npe tawm ntawm qhov kev xeem zaum kawg. Qhov kev sib xyaw ua ke ntawm cov khoom siv tes ua, kev kuaj xyuas, thiab kev ua haujlwm pab pawg ua rau cov transformers txhim khu kev qha hauv cov xwm txheej hnyav.

2.3 Tank

Lub tshuab hluav taws xob siv lub tank ntim cov roj kaw- kaw tag nrho, siab- nruj, ua kom muaj zog welded tsim. Tsis muaj pores, tsis muaj sloppy seams. Tom qab vuam, lub tank mus dhau lub tshuab nqus tsev lossis cua - kev ntsuas nruj. Cov txheej txheem txheej yog sab nraum zoov- qib: epoxy primer ntxiv rau polyurethane tiav, nrog rau txhua yam khoom siv corrosion- tiv thaiv. Terminals ua raws li cov qauv kev teeb tsa, thiab qhov chaw khaws cia rau cov neeg ntes thiab cov ntsiab lus hauv av yam tsis muaj kev cuam tshuam rau lub zog nqa lossis lub kaum sab xis. Zoo meej rau huab cua ntxhib thiab kev pabcuam ntev.

04 Kev teeb tsa

Kev teeb tsa tus ncej-Mounted Transformer
Kev npaj qhov chaw
Xaiv qhov chaw tsim nyog rau lub transformer. Hauv av yuav tsum ruaj khov thiab siv tau, thiab qhov chaw yuav tsum nyob ze rau cov kab hluav taws xob uas twb muaj lawm. Tshem tawm tej pob zeb, tej nroj tsuag, lossis tej kev thaiv hauv cheeb tsam.
Ncej tshuaj xyuas
Tshawb xyuas tus ncej hluav taws xob ua ntej kev teeb tsa. Xyuas kom nws muaj suab nrov, tsis muaj kab nrib pleb lossis lwj, thiab muaj peev xwm txhawb nqa lub tshuab hloov pauv qhov hnyav.
Transformer Inspection
Tshawb xyuas lub transformer rau tej yam tshwm sim ntawm kev puas tsuaj. Tshawb xyuas cov bushings, terminals, thiab cov khoom cua txias kom paub meej tias lawv huv thiab zoo.
Mounting lub Transformer
Siv lub crane los yog hoist nqa lub transformer rau hauv txoj hauj lwm. Ua kom ruaj khov rau tus ncej nrog bolts thiab mounting brackets. Xyuas kom nws yog theem thiab ruaj khov.
Kev sib txuas hluav taws xob
Txuas lub siab -voltage thiab low-voltage leads raws li cov chaw tsim khoom cov lus qhia. Xyuas kom tag nrho cov terminals huv si, nruj, thiab ua kom zoo.
Hauv av
Txuas tus neeg xyuas pib hauv av mus rau ib qho kev pom zoo hauv av lossis cov av hauv av. Qhov no muab kev nyab xeeb tiv thaiv hluav taws xob tsis zoo thiab txhim kho kev ntseeg tau.
Kev sim
Tom qab kev teeb tsa, ua cov qauv ntsuas hluav taws xob xws li rwb thaiv tsev tiv thaiv, polarity, thiab ntsuas hluav taws xob. Paub meej tias lub transformer ua haujlwm kom raug ua ntej energizing.

Kev soj ntsuam zaum kawg
Tus thawj saib xyuas lossis engineer yuav tsum ua qhov kev tshuaj xyuas zaum kawg. Hais txog tej teeb meem lossis kev hloov kho raws li xav tau kom ua tau raws li cov qauv kev nyab xeeb thiab zoo.
Cov ntaub ntawv
Sau tag nrho cov qhabnias xeem, cov ntaub ntawv cov khoom siv, thiab cov ntawv sau. Khaws cov ntaub ntawv no rau kev saib xyuas thiab siv yav tom ntej.
