Hauv kev lag luam hluav taws xob, hluav taws xob hluav taws xob nws tus kheej tsis yog lub sijhawm tseem ceeb tshaj plaws.Lub sijhawm rhiab thiab pheej hmoo tshaj plaws yog lub sijhawm thaum lub zog rov qab los.
Hauv ntau lub chaw tsim khoom, cov chaw tsim hluav taws xob, thiab cov chaw tsim khoom, nws yog ib qho kev coj ua uas yuav tsum tau ua tom qab lub zog rov qab los:
tsuas yog ib qho tseem ceeb nkaus xwb -theem loads raug tso cai, thaum peb -theem khoom yuav tsum nyob twj ywm ib ntus.
Qhov no tsis yog ib txoj cai sab hauv xwb. Nws yog kev txiav txim siab raws li cov qauv kev ua haujlwm ntawm lub tshuab hluav taws xob thiab lub zog hluav taws xob kev nyab xeeb.
Fais fab Restoration tsis txhais hais tias lub Transformer yog ruaj khov
Los ntawm kev xav txog hluav taws xob engineering, lub transformer tsis rov qab mus rau "zero state" tom qab qhov hluav taws xob.
Thaum lub hwj chim rov qab los, lub transformer tseem tuaj yeem ntsib:
- Residual magnetic flux nyob rau hauv lub core
- Ib qho mob tsis ruaj khov magnetization
- Ib ntus elevated inrush thiab excitation tam sim no
Thaum lub sij hawm no, lub transformer tseem tab tom hloov los ntawm qhov zoo li qub mus rau ib txwm ua haujlwm.
Yog hais tias hnyav loads tam sim ntawd, hluav taws xob kev nyuaj siab ntawm lub transformer yuav nce ho.
Vim li cas Tib -Theem Loads raug tso cai ua ntej
Ib zaug -phase loads feem ntau muaj:
- Tsawg zog xav tau
- Tsawg kawg pib tam sim no
- Txwv tsis pub muaj kev cuam tshuam rau kev thauj khoom ntawm transformer
Teeb pom kev zoo, cov cuab yeej siv hauv chaw ua haujlwm, thiab cov khoom siv sib txuas lus raug txiav txim siablow- cuam tshuam loads.
Tso cai rau cov loads ua haujlwm ua ntej pab lub transformer maj mam tsim cov hlau nplaum thiab thermal stability yam tsis muaj kev ntxhov siab ntau dhau.
Los ntawm kev ua haujlwm transformer standpoint, qhov no yog atswj thiab nyab xeeb- txheej txheem.
Qhov Kev pheej hmoo tiag tiag ntawm Peb - Cov Khoom Siv Theem Lies hauv Startup Tam sim no
Feem ntau peb -theem cov cuab yeej, tshwj xeeb tshaj yog lub cev muaj zog- tsav tsheb thauj khoom, ua rau muaj qhov tam sim no siab heev thaum pib.
Qhov pib tam sim no tuaj yeem ncav cuagtsib mus rau xya npaug ntawm qhov ntsuas tam sim no.
Yog tias ntau peb -theem tshuab pib ib txhij thaum lub zog tsuas yog rov qab los, lub kaw lus yuav ntsib:
- Sudden voltage poob
- Luv - lub sij hawm transformer overloading
- Tsis xav tiv thaiv relay mus ncig ua si
- Rov ua dua lub zog cuam tshuam
Cov xwm txheej zoo li no ua rau muaj kev ntxhov siab tsis tsim nyog rau kev hloov pauv windings, rwb thaiv tsev tshuab, thiab kev pabcuam tag nrho lub neej.
Yog vim li cas Transformer Manufacturing Facilities yog rhiab heev
Hauv transformer factories thiab cov khoom siv hluav taws xob, cov tshuab hluav taws xob feem ntau muaj xws li:
- Qhov feem ntau ntawm peb -theem loads
- Khoom siv nrog nruj voltage stability yuav tsum
- Sib koom kev faib tshuab rau kev tsim khoom, kev sim, thiab cov chaw pabcuam
Txhua qhov kev thauj khoom tsis raug rov qab thaum lub zog rov qab tuaj yeem ua kom muaj kev pheej hmoo ntawm lub cev.
Yog li ntawd,staged load rov qab thiab tswj energizationyog cov qauv kev coj ua hauv kev lag luam transformer.
Ib qho kev pib tsis raug tuaj yeem raug nqi ntau dua li qhov hluav taws xob poob
Lub zog hluav taws xob luv luv feem ntau ua rau muaj kev puas tsuaj tsawg dua li rov pib dua cov cuab yeej hnyav hauv cov hluav taws xob tsis ruaj khov.
Daim ntawv thov load tsis raug thaum lub sijhawm hloov pauv tuaj yeem ua rau:
- Thermal stress ntawm windings
- Accelerated rwb thaiv tsev laus
- Kev puas tsuaj zais uas txo cov kev cia siab ntev ntev -
Cov teebmeem no yuav tsis ua rau tsis ua haujlwm tam sim ntawd tab sis tuaj yeem ua rau luv luv transformer lifespan.
Xaus
Transformers yog qhov txuas tseem ceeb ntawm daim phiaj hluav taws xob thiab qhov kawg - siv cov khoom siv.
Kev hwm tus cwj pwm kev ua haujlwm ntawm lub tshuab hluav taws xob thaum lub sij hawm kho hluav taws xob yog qhov tseem ceeb rau kev ntseeg tau ntawm qhov system.
Tias yog vim li cas, nyob rau hauv ntau qhov chaw lag luam, cov lus qhia
"ib zaug-phase loads tso cai, peb-theem khoom txwv"
tsis yog ib qho qauv, tab sis qhov kev xav ntawm lub suab hluav taws xob engineering xyaum.
