Qhov kev ua tau zoo thiab kev pabcuam lub neej ntawm qhov qhuav -hom transformer feem ntau nyob ntawm kev xaiv thiab kev sib xyaw ntawm cov ntaub ntawv tseem ceeb. Daim ntawv thov cov ntaub ntawv tsim nyog tsis tsuas yog ua kom muaj kev sib haum xeeb ntawm cov hluav taws xob rwb thaiv tsev, kev siv lub zog, thiab cov cua sov, tab sis kuj txhim kho cov khoom siv hluav taws kub, dej tsis kam, thiab kev hloov pauv ib puag ncig, ua tau raws li cov kev cai nruj ntawm ntau yam kev thov.
Cov khoom siv tseem ceeb yog lub hauv paus ntawm kev sib nqus hluav taws xob thiab lub zog ua haujlwm ntawm lub tshuab ziab khaub ncaws -hom transformer. Tam sim no, siab -permeability txias- dov nplej- cov ntawv qhia txog silicon steel feem ntau yog siv. Lawv cov hlau tsis tshua muaj hlau tsis zoo thiab cov permeability siab txo qis tsis muaj- thauj khoom poob thiab kub nce. Lub thickness ntawm silicon steel los xij thiab qhov zoo ntawm cov txheej txheej rwb thaiv tsev ncaj qha cuam tshuam rau eddy tam sim no poob qib. Lub siab- txheej txheej zoo tuaj yeem txo qhov cuam tshuam ntawm -daim ntawv eddy tam sim no thiab txhim kho kev siv hluav taws xob tag nrho. Hauv qee daim ntawv thov tshwj xeeb, kom ua tiav qhov kev poob qis thiab suab nrov, ultra- cov ntawv tshwj xeeb nyias lossis cov khoom siv amorphous alloy tuaj yeem xaiv. Txawm hais tias tus nqi siab dua, lawv muab cov txiaj ntsig zoo hauv kev txuag hluav taws xob thiab txo qis emission.
Kev xaiv ntawm cov ntaub ntawv winding conductor muaj feem xyuam rau cov conductivity thiab thermal stability. Cov kev daws teeb meem tseem ceeb yog oxygen -dawb tooj liab lossis aluminium alloy. Copper conductors muaj cov conductivity siab thiab muaj zog oxidation tsis kam, txo tsis kam thiab kub tsim rau tib tug ntoo khaub lig-sectional cheeb tsam. Aluminium conductors yog lub teeb yuag thiab pheej yig, haum rau tej yaam num nrog hnyav rhiab heev los yog nyiaj txiag txwv. Txawm hais tias siv cov khoom siv, tus neeg xyuas pib saum npoo yuav tsum tau insulated los yog coated los tiv thaiv inter-tig thiab inter- theem tawg.
Cov txheej txheem rwb thaiv tsev yog lub hauv paus kev ruaj ntseg thaiv ntawm qhuav- hom transformers. Epoxy resin cam khwb cia cov khoom siv hnyav-dawb epoxy resin raws li cov matrix, ntxiv cov tshuaj tua kab mob, muab tshuaj, thiab cov nplaim hluav taws kub hnyiab los ua cov khoom siv hluav taws xob sib xyaw ua kom muaj zog. Tom qab lub tshuab nqus tsev casting thiab kho, cov windings yog tag nrho encapsulated, muab hluav taws xob zoo rwb thaiv tsev, mechanical tiv thaiv, thiab ya raws. Rau cov khoom tsis yog- nrum, siab- kub resistant thiab nplaim taws- cov ntaub ntawv retardant xws li iav fiber reinforced resin, Nomex ntawv, thiab polyimide zaj duab xis yog feem ntau siv, tswj kev ruaj ntseg rwb thaiv tsev nyob rau lub sij hawm ntev ntawm qhov kub thiab txias. Kev xaiv cov khoom siv yuav tsum xav txog ob qho tib si qhov ntsuas kub tsis kam (piv txwv li, B, F, H) thiab qhov kub thiab txias ntawm qhov chaw ua haujlwm kom tsis txhob muaj kev laus thaum ntxov.
Thaum tshav kub kub dissipation thiab structural cov ntaub ntawv tseem ceeb heev. Cov txheej txheem sab nrauv thiab cov ncej txhawb nqa feem ntau yog ua los ntawm cov qib siab -zoo txias- cov ntawv yob steel lossis galvanized steel ntawv. Lub qub muaj zoo formability thiab siab zog, thaum lub tom kawg muaj zog corrosion kuj. Kev xaiv tuaj yeem ua raws li kev nyab xeeb yam ntxwv ntawm qhov chaw teeb tsa. Cov kiv cua txias ntawm cov cua- cov qauv txias yog feem ntau ua los ntawm aluminium alloy lossis engineering yas. Lub qub muaj lub zog siab thiab lub neej ua haujlwm ntev, thaum tom kawg yog lub teeb yuag thiab qis - suab nrov.
Nyob rau hauv cov nqe lus ntawm kev tiv thaiv thiab sealing, lub sealing strips feem ntau yog ua los ntawm EPDM roj hmab los yog silicone roj hmab, uas muaj zoo huab cua tsis kam, kub kuj, thiab kev laus kuj. Lawv tuaj yeem tiv thaiv kom tsis txhob ya raws thiab plua plav nkag thiab tswj kom muaj kev ruaj ntseg nyob hauv ib puag ncig.
Zuag qhia tag nrho, kev xaiv cov khoom siv rau qhuav- hom transformers yuav tsum ua kom tiav qhov sib npaug ntawm kev ua haujlwm hluav taws xob, lub zog siv hluav taws xob, hluav taws xob tiv thaiv thiab nplaim hluav taws, kev hloov pauv ib puag ncig, thiab kev lag luam. Kev tsim nyog ntawm silicon steel los xij, conductors, rwb thaiv tsev, thiab cov khoom siv sib txawv rau qib sib txawv, muaj peev xwm, thiab kev ua haujlwm ib puag ncig tuaj yeem tsis tsuas yog txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm cov cuab yeej siv ua haujlwm tab sis kuj tseem muab kev lav phib xaub rau nws cov kev txhawb nqa thiab daim ntawv thov hauv vaj tsev ntsuab, kev faib hluav taws xob ntse, thiab lwm yam.
