Piv txwv li, qhuav- hom transformers tshem tawm cov roj tank thiab cov roj insulating, txais yuav cov cua txias thiab cov khoom rwb thaiv tsev, thiab tsim nyog rau sab hauv ntawm cov tsev uas muaj kev tiv thaiv hluav taws kub; roj-immersed transformers, nrog rau lawv cov kev ua tau zoo ntawm cov cua kub dissipation, yog haum rau sab nraum zoov loj -scale fais fab kis scenarios.

 

 

 

 

 

Kev xaiv cov khoom siv thiab cov qauv tsim ntawm transformer lub cev tseem ceeb yog lub hauv paus rau nws qhov kev ua tiav ntawm cov haujlwm tseem ceeb. Lub siab sib nqus permeability ntawm cov khoom siv hluav taws xob sib nqus, tsis tshua muaj kev tiv thaiv ntawm cov khoom siv hluav taws xob, kev sib cais muaj zog ntawm cov ntaub ntawv insulating, thiab kev txhawb nqa thiab kev tiv thaiv lub luag haujlwm ntawm cov khoom siv thiab cov khoom siv ua ke tsim cov khoom siv hluav taws xob zoo, nyab xeeb, thiab txhim khu kev qha. Nrog rau kev txhim kho txuas ntxiv ntawm cov tshuab hluav taws xob cov kev xav tau rau kev siv hluav taws xob thiab kev ntseeg tau, cov khoom siv hluav taws xob kuj tseem txhim kho lub zog ntau dua -txuag thiab ruaj khov. Piv txwv li, daim ntawv thov ntawm amorphous alloy cores thiab tshiab composite insulating cov ntaub ntawv yog maj nrov. Tus qauv tsim tau dhau los ua neeg txawj ntse. Los ntawm kev sib koom ua ke sensing thev naus laus zis thiab Internet ntawm Tej yam thev naus laus zis, kev saib xyuas meej thiab kev ua haujlwm ntse thiab kev saib xyuas ntawm kev ua haujlwm ntawm lub tshuab hluav taws xob tau paub. Kev nkag siab tob txog ntawm cov ntaub ntawv thiab cov qauv ntawm lub cev hloov pauv tseem ceeb yog qhov tseem ceeb tshaj plaws rau kev tsim, tsim khoom, kev ua haujlwm thiab kev saib xyuas, thiab kev kho dua tshiab ntawm cov cuab yeej siv, thiab tseem muab kev lav zoo rau kev ua haujlwm ruaj khov ntawm lub zog hluav taws xob.

Kuv tau ua tiav cov lus Askiv version ntawm tsab xov xwm nrog peb lub rooj sib piv. Koj puas xav kom kuv kho cov hom ntawv (xws li font, kab lus sib nrug) kom ua raws li cov lus qhia tshwj xeeb, lossis hloov cov ntsiab lus ntawm ib feem? Kuv kuj tseem tuaj yeem pab koj xa cov ntsiab lus raws li cov ntaub ntawv hauv Lo Lus formatted rau kev siv ncaj qha.
