Kev loj hlob ntawm qhuav-hom transformers

Txij li thaum lub tuam txhab German AEG tsim thawj 400kVA / 20kV epoxy cam khwb cia qhuav-hom transformer nyob rau hauv 1964, qhuav-hom transformers tau nkag mus rau theem ntawm kev loj hlob zoo. Nyob rau tib lub sijhawm, Tebchaws Meskas kuj tau tshawb pom Nomex rwb thaiv tsev ntawv, uas tuaj yeem siv los ua cov khoom siv rwb thaiv tsev ntawm H-class dry-type transformers. Yog li ntawd, muaj ob hom kev hloov pauv loj tam sim no, ib qho yog hom epoxy thiab lwm yam yog Nomex daim ntawv.
Tam sim no, nyob rau hauv cov teb chaws tsim kho xws li Tebchaws Meskas, Lub Tebchaws Yelemees, thiab Nyij Pooj, cov khoom siv hluav taws xob qhuav tau suav txog ntau dua 20% ntawm cov khoom siv hluav taws xob hloov pauv, thiab cov tshuab ziab khaub ncaws qhuav tau suav rau {{3} }% ntawm tag nrho substations.
Cov "2013-2017 Tuam Tshoj Dry-Type Transformer Industry Market Demand Forecast and Investment Strategy Planning Analysis Report" qhia tau tias kuv lub teb chaws tau dhau los ua lub teb chaws uas muaj ntau tshaj plaws thiab muag khoom ntawm cov transformers qhuav hauv ntiaj teb. Tam sim no, ntau yam khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob los ntawm txawv teb chaws muaj qee qhov tseem ceeb hauv kev lag luam, tab sis cov tshuab ziab khaub ncaws qhuav yuav luag tsis tau tuaj ntawm txawv teb chaws txij li thaum xaus ntawm lub xyoo pua 20th. Nyob rau hauv cov haujlwm tseem ceeb thiab cov haujlwm loj hauv Suav teb, nws nyuaj rau nrhiav cov kab txawv txawv teb chaws qhuav transformers. Raws li kev tsim kho tam sim no ntawm kuv lub teb chaws txoj kev sib kis network, qhov kev faib ua feem ntawm 10k V qhuav-hom transformers tau nce xyoo los ntawm 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 hluav taws xob tau nce zuj zus ib hnub. Feem ntau hais lus, rau txhua txhua 1kW nce hauv kev tsim hluav taws xob, tag nrho cov peev txheej hloov pauv yuav tsum tau nce los ntawm 11kVA; thiab Satons faib transformers account rau li 1/3-1/2 ntawm tag nrho cov transformer muaj peev xwm. Nws yog kwv yees hais tias qhuav-hom tis transformers account rau li 1/5-1/4 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 yog booming, thiab cov zis yuav tswj tau qhov kev loj hlob ntawm li 20% tom qab xyoo 2010. Raws li keeb kwm kev paub thiab kev hloov pauv ntawm cov qauv transformer voltage theem, qhov kev faib ua feem ntawm transformers yog hais txog. 40%. Raws li qhov kev faib ua feem ntawm 40%, kuv lub teb chaws qhov tshiab qhuav-hom transformer tso zis yuav ncav cuag li 200 lab KVA.
Hauv kuv lub tebchaws, xyoo 1966, Shenyang Transformer Factory tau ua tiav ZSG-1800/10 coj cua txias H-class qhuav-hom transformer, thiab Shanghai Transformer Factory ua tiav cov SG{{6} }/10/1.2/0.4 peb-coil nws tus kheej-txias H-class qhuav-hom transformer. Thaum xyoo 1970s, Shanghai Transformer Factory nws tus kheej tsim thiab tsim SCL{17}} epoxy cast transformer. [4] Nyob rau hauv 20 xyoo dhau los, nrog rau kev loj hlob ntawm lub ntiaj teb no kev lag luam, qhuav transformers tau ua tiav kev loj hlob sai thoob ntiaj teb, tshwj xeeb tshaj yog nyob rau hauv tis transformers. Raws li kev txheeb cais, hauv cov teb chaws tsim kho xws li Europe thiab Tebchaws Meskas, nws tau suav txog 40-50% ntawm cov khoom siv hluav taws xob. Hauv kuv lub tebchaws, nws suav txog li 50%. Los ntawm qhov kev xav ntawm cov zis, kuv lub teb chaws cov khoom qhuav-hom transformer tso zis tau nce ntau txij li lub rooj sib tham hauv nroog thib ob hauv lub zog hluav taws xob hloov pauv hauv xyoo 1989. Txij li xyoo 1990, nws tau nce ntawm tus nqi kwv yees li 20% hauv ib xyoos. Tag nrho cov khoom tsim tawm hauv xyoo 1999 yog ze rau 10,000 MVA (tus nqi no tau zoo heev tshaj li 4,500 MVA kwv yees 10 xyoo dhau los), thiab tag nrho cov zis hauv 2002 mus txog 20,000 MVA, thiab hauv 2004 nws mus txog 32, 000 MVA. Qhov kev loj hlob zoo li no tsis tau muaj dua nyob hauv lub ntiaj teb.
Los ntawm cov ntaub ntawv saum toj no, nws tuaj yeem pom tau tias kuv lub teb chaws tau dhau los ua ib lub teb chaws uas muaj ntau tshaj plaws thiab muag khoom ntawm cov tshuab ziab khaub ncaws qhuav hauv ntiaj teb, thiab tau nyob rau hauv lub ntiaj teb cov theem ua nyob rau hauv cov nqe lus ntawm lub Hoobkas nplai, cov khoom muaj peev xwm, voltage, thiab lwm yam.
