Hauv cov tshuab hluav taws xob niaj hnub no, cov roj 110kV -immersed peb -theem ob- winding transformer nrog unexcited voltage tswj yog nyob txhua qhov chaw. Nws yog ib qho ntawm cov khoom ruaj khov, tsis muaj -frills cov khoom siv uas tsuas yog tau txais txoj haujlwm ua tiav kev ntseeg siab thiab pheej yig.
Tsim thiab Yuav Ua Li Cas Tiag Tiag
Cov transformers no muaj peb yam classic-theem teeb nrog ob windings - high voltage thiab low voltage - tag nrho cov zaum nyob rau hauv ib lub tank uas muaj cov ntxhia roj. Cov roj saib xyuas cov rwb thaiv tsev thiab cua txias, txawm tias los ntawm kev ncig ntuj lossis nrog me ntsis kiv cua pab. Sab hauv, koj yuav pom cov tub ntxhais uas ua los ntawm qib siab -qib nplej- taw qhia silicon steel uas pab txo qis kev poob thiab ua kom lub suab nrov tsawg.
Qhov "tsis txaus siab" txhais tau tias koj tuaj yeem hloov cov kais dej xwb thaum lub tshuab hloov pauv hloov. Feem ntau cov kais dej yog nyob ib ncig ntawm ± 2 × 2.5% lossis ± 3 × 2.5%. Nws yooj yim dua thiab pheej yig dua li qhov zoo nkauj ntawm -load versions, uas yog vim li cas ntau cov khoom siv tseem nyiam nws. Feem ntau koj yuav pom qhov sib piv voltage xws li 110/35kV, 110/10.5kV, lossis 110/6.3kV, muaj peev xwm li ntawm 6.3MVA txog 63MVA.
Qhov twg cov Transformers siv
Koj yuav pom lawv feem ntau nyob rau hauv 110kV substations, nqis qis dua qhov hluav taws xob xa mus rau cov nroog, cov zej zog, thiab cov cheeb tsam me me.
Lawv kuj yog ib qho nyiam nyob rau hauv kev lag luam hnyav thiab kev lag luam mining. Thaum cov nroj tsuag loj lossis kuv xav tau lub zog muaj zog nyob rau hauv cov xwm txheej ntxhib - plua plav, noo noo, qhov kub thiab txias hloov pauv - cov chav no tuav tau zoo heev.
Cov nroj tsuag fais fab, suav nrog cov thermal me me, hydro, thiab cov haujlwm txuas ntxiv dua tshiab xws li cua thiab hnub ci ua liaj ua teb, siv lawv los txuas cov tshuab hluav taws xob rau 110kV kab sib chaws. Koj tseem yuav pom lawv ua haujlwm hnyav hauv kev tsheb ciav hlau traction substations, pab kom siab - ceev thiab hluav taws xob tsheb ciav hlau khiav zoo.
Thaum twg daim phiaj xav tau kev nthuav dav lossis hloov kho dua tshiab, cov tshuab hloov pauv no feem ntau yog siab ntawm daim ntawv vim tias lawv yog tus qauv, ncaj nraim rau nruab, thiab muaj cov ntaub ntawv ntev.
Vim Li Cas Tib Neeg Nyiam Lawv
Tus nqi yog ib qho loj ntxiv. Yog tsis muaj qhov nyuaj ntawm -load tap changer, lawv pheej yig dua los yuav thiab tswj. Lawv kuj muaj kev ntseeg siab heev - ntau ntawm lawv ua haujlwm ruaj khov rau ntau dua 30 xyoo. Cov qauv qis dua tshiab-cov qauv poob (xav tias S11 lossis S13 series) ua haujlwm tau zoo thiab tuaj yeem ua haujlwm luv luv yam tsis muaj hws.
Lawv yoog tau zoo rau cov huab cua sib txawv thiab xa cov kev ua tau zoo txawm tias thaum thauj khoom nce thiab nqis.
Hnub - mus rau - Hnub Ua Haujlwm thiab Kev Saib Xyuas
Kev teeb tsa yog tus qauv zoo nkauj: lub hauv paus zoo, qhov cua zoo, thiab qhov chaw txaus nyob ib puag ncig nws. Cov neeg ua haujlwm tsis tu ncua xyuas cov roj kub, roj theem, thiab cov roj yaj hauv qib. Kev kuaj roj niaj hnub thiab kev ntsuas hluav taws xob tsuas yog ib feem ntawm kev saib xyuas ib txwm muaj.
Txij li thaum koj yuav tsum kaw nws los kho cov kais dej, qee qhov kev npaj ua ntej yog xav tau. Tab sis qhov ntawd feem ntau yog kev lag luam ncaj ncees- tawm rau qhov yooj yim. Kev nyab xeeb nta xws li Buchholz relays thiab lub siab nyem li qub pab tiv thaiv cov teeb meem. Cov chav no feem ntau ua tau raws li IEC 60076 thiab cov qauv hauv zos.
Kev xav zaum kawg
Thaum kawg ntawm hnub, cov roj 110kV-immersed ob-winding transformer nrog off-circuit regulation tseem yog ib qho kev xaiv rau ntau lub tshuab hluav taws xob. Tej zaum nws yuav tsis yog qhov siab tshaj plaws - kev xaiv thev naus laus zis, tab sis nws yog qhov ua tau zoo, vam khom tau, thiab tau txais cov haujlwm ua tiav txhua xyoo. Raws li kev xav tau hluav taws xob loj hlob thiab ntau dua tuaj yeem koom nrog hauv kab sib chaws, cov kev ncaj ncees, nyuaj - cov hloov pauv ua haujlwm yuav ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob ruaj khov.
