01 General
1.1 Project Background
75 kVA ib theem ncej mounted transformer tau xa mus rau Canada nyob rau hauv 2024. Lub zog ntsuas ntawm lub transformer yog 75 kVA nrog ONAN txias. Thawj qhov hluav taws xob yog 34.5kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.12 / 0.24kV, lawv tsim ib pawg vector ntawm Ii6.
Ib tug ncej mounted transformer yog ib hom fais fab transformer mounted rau ib tug xov tooj ncej, feem ntau nyob rau hauv txoj kev, txoj kev loj, los yog nyob rau hauv cov cheeb tsam. Cov transformers no ua lub luag haujlwm tseem ceeb hauv kev faib hluav taws xob los ntawm cov kab xa mus rau cov neeg siv, thiab yog cov khoom siv nruab nrab uas tswj cov qib voltage thiab xyuas kom muaj kev nyab xeeb thiab siv hluav taws xob zoo. Ib qho -theem ncej mounted transformer yog ib qho khoom siv hluav taws xob siv los xa hluav taws xob hluav taws xob ntawm ob lossis ntau lub circuits los ntawm electromagnetic induction. Nws feem ntau muaj ob lub xaim coils (hu ua thawj thiab theem nrab winding) qhov txhab nyob ib ncig ntawm cov tub ntxhais sib nqus sib nqus. Thaum alternating tam sim no (AC) ntws los ntawm thawj winding, nws tsim ib tug hloov magnetic teb nyob rau hauv lub tub ntxhais, uas nyob rau hauv lem induces ib tug voltage nyob rau hauv lub thib ob winding. Qhov hluav taws xob no tuaj yeem siab dua lossis qis dua qhov tseem ceeb ntawm qhov hluav taws xob, nyob ntawm qhov sib piv ntawm qhov hloov pauv ntawm cov thawj thiab theem nrab windings.

02 Kev tsim khoom
2.1 Core
Cov tub ntxhais yog ua los ntawm cov khoom txias txias-rolled grain-cov ntawv qhia txog silicon steel, feem ntau txhim kho nrog cov kev kho mob tshwj xeeb kom txo cov tub ntxhais poob. Cov tub ntxhais yog tsim los siv cov txheej txheem nruam winding, tsim ib qho seamless, kaw sib nqus sib nqus. Qhov kev tsim no txo cov hlau nplaum tiv thaiv los ntawm cov pob qij txha. Lub qhov txhab ntawm lub qhov txhab ua kom lub cev tsis sib xws thiab tsis tu ncua kev sib nqus, txo hysteresis thiab eddy tam sim no poob, yog li txhim kho kev ua haujlwm. Lub qhov txhab lub qhov txhab feem ntau muaj cov duab tsis tu ncua, uas txo qhov ntim thiab qhov hnyav, ua tau raws li qhov kev thov rau lub teeb yuag thiab yooj yim installation.
2.2 Cua txias
Precisely tsim lem piv ua kom lub voltage thiab tam sim no kev sib raug zoo ntawm cov thawj thiab theem nrab windings raws li specifications. Txo txo qhov sib nqus sib nqus los ntawm kev ua kom zoo ntawm tus neeg xyuas pib hla- ntu thiab kev npaj, ua kom muaj zog hloov pauv tau zoo. High- lub zog clamping cov qauv txhim khu kev tiv thaiv luv luv - Circuit Court quab yuam, tiv thaiv txhua yam deformation los ntawm electromagnetic stress. Thaum tshav kub kub generated nyob rau hauv lub winding yog zoo dissipated los ntawm inter-txheej txheej cua txias raws los yog ncig ntawm insulating roj, tiv thaiv kub kub nce.
2.3 Tank
Lub tank feem ntau yog ua los ntawm siab- zoo stainless hlau, nrog rau cov neeg kho tshuab siab zog thiab corrosion kuj, kom ntseeg tau ntev - lub sij hawm ruaj khov ntawm lub tank nyob rau hauv ib puag ncig hnyav. Sab nrauv yog coated nrog anti- xeb thiab tiv thaiv- xim xim, feem ntau nyob rau hauv lub teeb grey lossis lwm yam kev ua kom zoo ib puag ncig, tiv thaiv xeb thiab txuas ntxiv lub tank lub neej kev pab cuam. Advanced sealing welding cov txheej txheem kom ntseeg tau tias muaj zog, xau-cov ntaub ntawv pov thawj, tuav ruaj ntseg cia ntawm cov roj transformer. Advanced sealing welding cov txheej txheem kom ntseeg tau tias muaj zog, xau-cov ntaub ntawv pov thawj, tswj kev ruaj ntseg ntawm cov roj hloov pauv.
2.4 Lub Rooj Sib Tham Kawg
(1) Coil Winding thiab sib dhos:
- Cua lub hauv paus thiab theem nrab coils siv cov khoom siv xws li tooj liab lossis txhuas hlau.
- Txhim kho lub qhov txhab coils rau hauv cov tub ntxhais, kom ntseeg tau tias qhov chaw raug thiab hluav taws xob sib txuas ntawm cov coils.
(2) Kev kho rwb thaiv tsev:
- Muab cov ntaub ntawv insulating ntawm cov coils thiab lwm qhov chaw nyob kom tsis txhob muaj hluav taws xob poob siab thiab luv luv Circuit Court.
(3) Tank Assembly:
- Muab cov tub ntxhais sib dhos thiab coils rau hauv lub tank transformer.
- Sau lub tank nrog cov roj transformer kom txias thiab rwb thaiv tsev lub hom phiaj.
(4) Txhim kho cov khoom siv sab nraud:
- Txhim kho cov khoom siv sab nraud xws li cov ntsuas roj ntsuas, ntsuas qhov ntsuas kub, thiab lub siab nyem li qub txhawm rau saib xyuas kev ua haujlwm ntawm lub tshuab hloov pauv.
- Nruab qhov txuas txuas thiab lwm yam khoom siv hluav taws xob sib txuas tsim nyog.
