Saib ntawm kev txhim kho keeb kwm ntawm transformer zog-txuag thev naus laus zis, transformers tau dhau los ua ntau yam kev hloov pauv, suav nrog S6, S7, S9, thiab S11 series. Tam sim no, S9 lub zog-cov khoom txuag tau dhau los ua kev lag luam tseem ceeb, thaum lub lag luam loj ntawm S11 lub zog-cov khoom txuag tau loj hlob. Thaum lub sij hawm nce qib ntawm S11, tus nqi muag ntawm S11 yog nyob rau nruab nrab 14.2% siab dua li ntawm S9, yog li tus nqi tseem yog qhov tseem ceeb cuam tshuam rau qhov nrov thiab nce qib ntawm S11 transformers. Tam sim no, txawm hais tias cov khoom tshiab S9 tau nyob hauv kev lag luam loj, nrog kev txhim kho kev lag luam, qhov kev thov rau S11 cov khoom lag luam los ntawm cov neeg siv (tshwj xeeb tshaj yog nyob deb nroog cov phiaj xwm hluav taws xob thiab cov neeg siv nrog cov nqi hluav taws xob qis dua) yog maj mam nce. S11 hom laminated core transformer yog tsim thiab tsim raws li cov cuab yeej paub tab ntawm S9 tshiab, thiab nws cov ntsuas kev ua tau zoo tau txhim kho zoo thaum tswj cov khoom lag luam ntseeg tau. Piv nrog rau cov tsoos laminated transformers, S11 qhov txhab core faib transformers muaj cov yam ntxwv ntawm kev txuag cov ntaub ntawv raw, txuag hluav taws xob, txhim kho cov khoom siv hluav taws xob zoo, tsis muaj suab nrov, thiab qib siab ntawm kev siv tshuab.
Roj-immersed transformers siv roj-cov ntaub ntawv rwb thaiv tsev. Nws cov txheej txheem tseem ceeb yog kev kho kom qhuav ntawm cov ntaub ntawv rwb thaiv tsev thiab lub tshuab nqus dej ntawm lub transformer. Vapor theem ziab: Nyob rau hauv nruab nrab -1980s, Tuam Tshoj transformer manufacturers yog thawj coj vapor theem ziab khoom los ntawm Switzerland. Nyob rau hauv xyoo tas los no, ib qho khoom tshiab, cov khoom siv hluav taws xob ua ke tau tsim ua kerosene evaporator. Piv nrog rau cov tsoos sab nraud evaporator, ob leeg muaj lawv qhov zoo thiab qhov tsis zoo. Transformer roj kev kho mob: Nkag mus rau xyoo 1980s, nrog kev qhia txog cov cuab yeej siv roj pom zoo los ntawm cov teb chaws Europe thiab Amelikas, Tuam Tshoj cov roj purification technology tau ua kom muaj kev vam meej. Cov tuam txhab lag luam feem ntau tau txais kev siv lub tshuab nqus tsev nqus cov roj purification txoj kev, uas muaj cov txiaj ntsig zoo kawg nkaus rau kev tshem tawm impurity thiab lub cev qhuav dej.
