Classification ntawm Main Transformer
Lub ntsiab transformer feem ntau yog ib qho cuab yeej siv lub hauv paus ntsiab lus ntawm electromagnetic induction los hloov AC voltage. Lub ntsiab Cheebtsam yog thawj kauj, theem nrab kauj thiab hlau core (core). Lub luag haujlwm tseem ceeb suav nrog kev hloov pauv hluav taws xob, hloov pauv tam sim no, hloov pauv impedance, kev sib cais, kev tswj hluav taws xob (magnetic saturation transformer). Txhawm rau txhim kho kev nkag siab ntawm transformers, transformer manufacturers qhia cov kev faib ntawm lub ntsiab transformer nyob rau hauv tsab xov xwm no.
(1) Lub zog transformer
Tam sim no, cov khoom lag luam raug khiav ntawm lub cev yog 1150KV, 1200MV, 735 ~ 765KV, 800MV, 400 ~ 500KV peb-theem 750MV lossis ib theem 550MV. DC kis tau tus mob 500KV, 400MV rov qab transformer. Fais fab transformers feem ntau yog cov roj raus, thiab cov khoom tsim muaj ob hom: sib sib zog nqus hom thiab plhaub. Cov tub ntxhais thiab lub plhaub tsis muaj qhov muaj txiaj ntsig zoo dua ib leeg, tab sis cov tub ntxhais kawm yog qhov yooj yim thiab yog li tau txais los ntawm cov lag luam feem ntau. Lub plhaub qauv thiab txheej txheem yog qhov nyuaj dua, thiab tsuas yog cov chaw ua haujlwm ib txwm siv nws. Plhaub muaj qhov zoo ntawm high voltage, muaj peev xwm loj, rwb thaiv tsev, tshuab, thiab cua sov, thiab tsim nyog rau kev thauj mus los hauv roob hydropower chaw nres tsheb.
Fais fab transformers yog ib qho ntawm cov cuab yeej tseem ceeb hauv cov chaw tsim hluav taws xob thiab cov chaw ua haujlwm. Lub luag hauj lwm ntawm lub transformer tsis yog tsuas yog ua kom muaj qhov hluav taws xob ntau ntau thiab xa hluav taws xob mus rau thaj chaw hluav taws xob, tab sis kuj txo qhov hluav taws xob rau kev siv hluav taws xob ntawm txhua theem kom tau raws li qhov xav tau ntawm lub zog. Nyob rau hauv luv luv, lub ntsiab transformer manufacturers ntseeg hais tias ob qho tib si step-up thiab step-down yuav tsum tau ua kom tiav nrog ib tug transformer. Nyob rau hauv cov txheej txheem ntawm kev xa hluav taws xob hauv lub zog hluav taws xob, ob qhov kev poob ntawm qhov hluav taws xob thiab lub zog yuav tshwm sim. Thaum xa cov hluav taws xob tib yam, qhov poob qhov hluav taws xob yog inversely proportional rau qhov voltage, thiab lub zog poob yog inversely proportional rau lub square ntawm voltage. Kev siv cov khoom siv hluav taws xob kom nce qhov hluav taws xob txo qis kev sib kis.
(2) Fais fab transformer
Lub tshuab hluav taws xob faib hluav taws xob yog cov khoom siv hluav taws xob zoo li qub nyob rau hauv lub zog faib hluav taws xob, uas yog siv los hloov hluav taws xob hloov pauv thiab tam sim no raws li txoj cai ntawm electromagnetic induction kom xa cov alternating tam sim no. Lub peev xwm ntawm kev xa tawm txawv teb chaws tuaj yeem ncav cuag 2500KV, thiab muaj cov qauv puag ncig thiab oval. Lub voj voog yog feem ntau, thiab lub ellipse yog M0 (qhov sib nrug ntawm cov hlau tseem ceeb) yog me me, yog li cov khoom raug txo, thiab cov coil sib txuas yog ellipse. Cov hluav taws xob qis qis muaj cov hlau thiab cov ntawv ci, thiab cov roj tank muaj cov cua kub cua sov (ob peb) thiab hom yoj (feem ntau).
(3) Qhuav hom transformer
Lub tshuab ziab khaub ncaws qhuav yog tsim los ntawm cov tub ntxhais hlau uas muaj cov ntawv silicon steel thiab cov epoxy resin txhaj coil. Ib lub tog raj kheej insulating yog muab tso rau nruab nrab ntawm qhov siab thiab qis voltage coils kom nce hluav taws xob rwb thaiv tsev. Muaj kev tshaj tawm xov xwm. Transformer manufacturers ntseeg hais tias muaj plaub lub qauv: txhaj tshuaj epoxy, txhaj tshuaj, qhwv thiab impregnated. Cov tshuab ziab khaub ncaws qhuav feem ntau siv rau hauv qhov chaw uas muaj kev ua haujlwm siab xws li kev tiv thaiv hluav taws thiab tawg-pov thawj vim lawv lub zog luv luv-circuit tsis kam, tsis tshua muaj txij nkawm, kev ua haujlwm siab, me me thiab tsis muaj suab nrov.
