Roj-immersed transformers yog kaw cov ntaub ntawv rwb thaiv tsev uas siv cov roj rwb thaiv tsev. Roj-immersed transformers yog dav siv nyob rau hauv lub hwj chim mov ntawm pej xeem kev tsim kho thiab yog ib qho ntawm cov khoom tseem ceeb hauv cov khoom siv hluav taws xob. Yog li dab tsi yog lub luag haujlwm ntawm cov roj hauv cov roj-immersed transformers?
Raws li tau hais ua ntej,roj-immersed transformerssiv cov roj rwb thaiv tsev ua cov khoom siv rwb thaiv tsev, yog li hom hluav taws xob hloov hluav taws xob no muaj qhov cuam tshuam rau rwb thaiv tsev. Tsis zoo li cov tshuab ziab khaub ncaws qhuav, cov tub ntxhais hlau thiab cov cua kub ntawm cov roj-immersed transformers yog immersed nyob rau hauv cov roj puv roj tank. Cov roj rwb thaiv tsev muaj kev ua haujlwm ntawm cov cua sov dissipation.
Thawj qhov ua haujlwm ntawm cov roj hauv cov roj-immersed transformers yog rwb thaiv tsev, ua lub zog dielectric ntawm transformer roj thiab roj. Immersing rwb thaiv tsev cov ntaub ntawv nyob rau hauv cov roj tsis tsuas yog txhim kho lub zog dielectric, tab sis kuj tiv thaiv qhov yaig ntawm noo noo. Qhov thib ob muaj nuj nqi ntawm transformer roj yog kub dissipation. Transformer roj muaj cov cua kub tshwj xeeb thiab tuaj yeem siv los ua cov dej txias. Thaum tshav kub kub generated thaum lub sij hawm transformer ua hauj lwm yuav ua rau kom lub thermal expansion ntawm cov roj nyob ze ntawm cov hlau core thiab windings. Los ntawm convection ntawm roj thiab tshav kub dissipation los ntawm lub radiator, ib txwm ua hauj lwm ntawm transformer roj yuav guaranteed.
