Txij li thaum lub tuam txhab German AEG tau tsim thawj 400kVA / 20kV epoxy- nrum qhuav- hom transformer hauv xyoo 1964, qhuav - hom transformers tau nkag mus rau lub sijhawm ntawm kev loj hlob sai. Tib lub sijhawm, Tebchaws Meskas tau tshawb pom Nomex insulating ntawv, uas tuaj yeem siv los ua cov khoom siv rwb thaiv tsev rau H-chav qhuav- hom transformers. Yog li, tam sim no muaj ob yam tseem ceeb ntawm qhuav{10}} hom transformers: epoxy hom thiab Nomex hom ntawv.
Tam sim no, nyob rau hauv cov teb chaws tsim kho xws li Tebchaws Meskas, Lub Tebchaws Yelemees, thiab Nyij Pooj, kev tsim cov tshuab ziab khaub ncaws rau ntau tshaj 20% ntawm cov khoom siv hluav taws xob hloov pauv, thiab hauv cov tshuab ua tiav substation, qhuav - hom transformers account rau 80-90%.
"2013-2017 Tuam Tshoj Qhuav-Type Transformer Industry Market Demand Forecast and Investment Strategy Planning Analysis Report" qhia tias kuv lub teb chaws tau dhau los ua tus tsim khoom loj tshaj plaws hauv ntiaj teb thiab muag khoom qhuav- hom transformers. Tam sim no, ntau yam khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob los ntawm txawv teb chaws nyob qhov tseem ceeb ntawm kev lag luam hauv tsev, tab sis qhuav- hom transformers tau yuav luag tag nrho tshem tawm los ntawm kev xa khoom txij li xyoo pua 20th. Txawv txawv teb chaws qhuav- hom transformers tsis tshua pom nyob rau hauv cov haujlwm tseem ceeb thiab cov haujlwm tseem ceeb hauv Suav teb. Raws li lub koom haum tam sim no ntawm kuv lub teb chaws lub zog xa hluav taws xob network, qhov kev faib ua feem ntawm 10kV qhuav-hom transformers yog nce txhua xyoo.
Tam sim no, txoj kev loj hlob ntawm kev tsim hluav taws xob hauv nroog thiab nyob deb nroog tau nrawm dua, thiab kuv lub teb chaws lub zog tsim hluav taws xob thiab kev siv tau nce txhua hnub. Feem ntau hais lus, rau txhua 1kW nce hauv lub zog tsim hluav taws xob, yuav tsum muaj 11kVA ntxiv ntawm tag nrho cov peev txheej transformer; ntawm no, Satons faib transformers account rau kwv yees li 1/3 rau 1/2 ntawm tag nrho cov transformer muaj peev xwm. Nws yog kwv yees tias qhuav -hom faib transformers account rau kwv yees li 1/5 rau 1/4 ntawm tag nrho cov tis transformers. Tsav los ntawm kev nqis peev hauv kev tsim hluav taws xob hauv hluav taws xob, kev lag luam transformer muaj kev loj hlob, nrog rau kev tsim khoom yuav tsum muaj kev loj hlob ntawm ib ncig ntawm 20% tom qab xyoo 2010. Raws li keeb kwm kev paub dhau los thiab kev hloov pauv ntawm transformer voltage theem qauv, qhov kev faib ua feem ntawm transformers yog nyob ib ncig ntawm 40%. Muab xam raws li 40% kev faib ua feem no, kuv lub teb chaws cov tshiab tshiab qhuav qhuav{19}} hom transformer ntau lawm yuav ncav cuag kwv yees li 200 lab kVA.
Hauv kuv lub tebchaws, xyoo 1966, Shenyang Transformer Factory tau tsim lub ZSG-1800/10 directional cua-cooled H-chav qhuav-hom transformer, thiab Shanghai Transformer Factory tau tsim lub SG3-800/10/1.2{1.2} tus kheej-txias H-class qhuav-hom transformer. Thaum xyoo 1970s, Shanghai Transformer Factory nws tus kheej tsim thiab tsim SCL-630 epoxy resin cam khwb cia transformer.
Nyob rau hauv 20 xyoo dhau los, nrog rau kev loj hlob ntawm lub ntiaj teb no kev lag luam, qhuav- hom transformers tau ua tiav kev loj hlob sai thoob ntiaj teb, tshwj xeeb tshaj yog nyob rau hauv kev faib transformers, qhov feem ntau ntawm qhuav- hom transformers tau loj thiab loj. Raws li kev txheeb cais, hauv cov teb chaws tsim kho xws li Europe thiab Tebchaws Meskas, nws tau suav txog 40 txog 50% ntawm cov khoom siv hluav taws xob. Hauv kuv lub tebchaws, nws suav txog li 50%. Hais txog cov khoom tsim tawm, txij li Lub Rooj Sib Tham Thib Ob Hauv Nroog Fais Fab Kev Txhim Kho hauv xyoo 1989, kuv lub teb chaws qhuav{10}} hom transformer ntau lawm tau pom kev loj hlob, nce ntawm tus nqi kwv yees li 20% txhua xyoo txij li xyoo 1990. Tag nrho cov khoom tsim tawm hauv xyoo 1999 mus txog 10,000 MVA (qhov tseem ceeb tshaj li 4,500 MVA kwv yees 10 xyoo ua ntej), mus txog 20,000 MVA hauv 2002, thiab nce siab ntawm 32,000 MVA hauv 2004. Cov kev loj hlob zoo li no tsis tau muaj dua nyob hauv ntiaj teb.
Raws li cov ntaub ntawv saum toj no qhia tau hais tias, kuv lub teb chaws tau dhau los ua ib lub ntiaj teb cov neeg tsim khoom loj tshaj plaws thiab cov muag khoom ntawm qhuav- hom transformers, ua lub ntiaj teb no hauv Hoobkas nplai, cov khoom muaj peev xwm, thiab qhov ntsuas hluav taws xob.
