Fais fab transformers yog zoo nkauj npaum li tus txha nraub qaum ntawm ib daim phiaj hluav taws xob-lawv yog qhov ua rau nws muaj peev xwm xa hluav taws xob ntau dhau mus ntev yam tsis tau nkim feem ntau ntawm nws thaum tshav kub kub, thiab tom qab ntawd xa mus rau hauv tsev, chaw ua haujlwm, thiab chaw ua haujlwm.
Nyob rau hauv lub plawv ntawm nws, tej yam no ua hauj lwm ntawm ib tug zoo nkauj ntse tab sis ncaj txoj cai: electromagnetic induction. Koj muaj lub hauv paus kauj uas yuav siv sij hawm nyob rau hauv lub zog tuaj, tsim ib tug hloov magnetic teb nyob rau hauv ib tug laminated hlau los yog steel core. Qhov chaw ntawd ces induces voltage nyob rau hauv lub thib ob kauj. Los ntawm kev muaj ntau dua los yog tsawg dua ntawm cov xaim hauv ib lub kauj piv rau lwm qhov, koj tuaj yeem nce qhov hluav taws xob nce (siab dua rau sab thib ob) lossis qis dua. Tsis muaj qhov txav mus los, txhim khu kev qha zoo thaum khaws cia kom zoo, thiab kev ua haujlwm feem ntau hits 98-99%-txawm tias cov kev poob me me tseem tseem ceeb heev ntawm daim phiaj teev.
Vim li cas lawv thiaj li tseem ceeb heev hauv daim phiaj
Yog tsis muaj transformers, xa hluav taws xob zoo yuav ua tsis tau. Cov tshuab tsim hluav taws xob tsim hluav taws xob ntawm qhov tsis tshua muaj hluav taws xob, tab sis txhawm rau thawb nws ntau pua mais ntawm cov kab uas tsis muaj qhov poob loj I²R, peb yuav tsum tau crank qhov hluav taws xob txoj kev nce mus txog -qee zaus mus txog 500kV lossis ntau dua. Kauj ruam- nce transformers ntawm fais fab nroj tsuag ua li ntawd. Tom qab ntawd, thaum lub zog tau los ze zog rau cov neeg siv, cov kauj ruam -kuj hloov pauv coj nws rov qab mus rau qib kev nyab xeeb dua li 11kV rau kev faib tawm, thiab thaum kawg mus rau 220/380V (lossis 110/120V hauv qee qhov chaw) rau kev siv txhua hnub.
Lawv kuj pab ua kom cov khoom ruaj khov: tswj qhov hluav taws xob, tuav lub viav vias thauj khoom, tiv thaiv overloads ntawm kab, thiab txawm tias cais cov cuab yeej rhiab hauv cov chaw xws li tsev kho mob.
Hom Lub Npe thiab qhov twg lawv siv
Kauj ruam - nce transformers: Feem ntau ntawm cov chaw tsim khoom. Boost low generator voltage mus rau high kis tau tus mob mus slash poob nyob deb.
Kauj ruam -down transformers: Txhua qhov chaw los ntawm substations mus rau cov zej zog. Tshem tawm qhov hluav taws xob siab kis mus rau ib yam dab tsi siv tau thiab nyab xeeb.
Fais fab transformers: Qhov kawg theem-ncej-mounted lossis ncoo-mounted cov uas pub txoj kev thiab cov tsev. Lawv me me tab sis muaj ntau heev.
Fais fab transformers(cov khoom hnyav-cov haujlwm hnyav): Cov tsiaj loj loj substation tuav cov khoom siab-voltage hloov, feem ntau 100MVA+.
Kev rho tawm transformers: Muab galvanic sib cais ntawm circuits rau kev nyab xeeb- tsis muaj hluav taws xob txuas ncaj qha, zoo rau cov iav rhiab heev lossis tiv thaiv kev poob siab.
Autotransformers: Qhia tawm ib qho winding, yog li lawv sib dua, pheej yig dua, thiab ua haujlwm zoo dua rau kev hloov pauv me me, tab sis tsis muaj kev sib cais tag nrho.
Koj yuav pom cov roj- ntim rau cov hauj lwm sab nraum zoov loj (roj txias thiab rwb thaiv tsev), qhuav- hom rau sab hauv tsev lossis hluav taws- qhov chaw rhiab, thiab lwm yam.
Cov ntsiab lus tseem ceeb (Lub Anatomy)
Core: Laminated silicon steel los coj cov sib nqus flux thiab txiav eddy tam sim no / hysteresis poob.
Cua txias: Feem ntau tooj liab (qee zaum txhuas) coils-thawj siv cov tswv yim, cov khoom siv thib ob.
Roj tank/conservator: Tuav cov roj insulating / txias, nthuav / cog lus nrog kub.
Bushings: Insulated connectors uas cia siab -voltage cables nkag / tawm yam xyuam xim.
Coj mus rhaub cov hloov pauv: Kho qhov hloov pauv me ntsis kom zoo- kho qhov tso zis hluav taws xob raws li qhov sib txawv ntawm cov loads (ntawm -load ones hloov tau).
Cov tshuab cua txias: Radiators, kiv cua, lossis cov twj tso kua mis kom pov tseg cov cua sov- ua kom cov khoom tsis kub dhau.
Losses thiab Efficiency Khoom
Txawm tias zoo transformers poob me ntsis: core poob (hysteresis + eddy tam sim no, ib txwm muaj), tooj liab poob (I²R nyob rau hauv windings, load-dependent). Cov qauv tsim niaj hnub siv cov ntaub ntawv zoo dua li amorphous steel cores lossis qis- poob windings los thawb kev ua haujlwm siab dua thiab txiav cov kev poob ntawd. Kev soj ntsuam ntse pab ntes cov teeb meem ntxov.
Kev saib xyuas tsis yog xaiv tau
Tej yam no kav ntau xyoo yog tias koj kho lawv zoo. Kev kuaj cov roj tsis tu ncua (kuaj xyuas cov dej noo, acidity), infrared scans rau qhov kub thiab txias, kev ntsuas rwb thaiv tsev, kev kuaj pom pom - hla lawv thiab cov teeb meem me me snowball rau hauv hluav taws xob lossis hluav taws kub. Niaj hnub no, ntau tus muaj cov sensors rau lub sijhawm tiag tiag - cov ntaub ntawv sijhawm, kev saib xyuas kev kwv yees, txawm tias cov menyuam ntxaib digital los simulate tus cwj pwm.
Dab tsi yog Hloov Lately
Kev lag luam txav nrawm-tshwj xeeb tshaj yog nrog cov khoom txuas ntxiv dua tshiab. Ntse transformers nrog IoT cia cov khoom siv saib xyuas kev thauj khoom, qhov kub thiab txias, ua txhaum ntawm kev deb, ua kom zoo dua qhov hluav taws xob, thiab kwv yees qhov ua tsis tiav. Ntau eco-kev xaiv tus phooj ywg: biodegradable kua siv cov roj ntxhia, qhuav- hom rau cov nroog, cov qauv tsim uas tswj cov tsiaj qus viav vias los ntawm hnub ci / cua zoo dua. Grid decentralization thiab microgrids xav tau hloov pauv hloov pauv ntau dhau.
Cov kab hauv qab: lub hwj chim transformers tsis flashy, tab sis lawv nyob ntsiag to ua qhov hnyav nqa kom cov hluav taws xob ntws tau ntseeg tau, ua tau zoo, thiab nce ntxiv. Raws li cov kab sib txuas tau ntse dua thiab ntsuab dua, cov neeg ua haujlwm no tau hloov kho txoj cai nrog rau lawv-kom paub tseeb tias peb tuaj yeem ua kom lub teeb kom tsis txhob nkim lub zog lossis ua phem rau lub ntiaj teb ntau tshaj qhov tsim nyog.
Yog tias koj tab tom dhia dej rau hauv qhov no rau kev ua haujlwm lossis tsuas yog xav paub, nws yog qhov txaus nyiam li cas ib yam dab tsi li "laus- tsev kawm ntawv" tseem yog lub hauv paus rau peb lub ntiaj teb lub zog niaj hnub no.
