Raws li cov cuab yeej tseem ceeb rau kev hloov pauv hluav taws xob thiab hluav taws xob xa mus rau hauv lub tshuab hluav taws xob, kev tsim thiab kev xaiv cov khoom siv hluav taws xob cuam tshuam ncaj qha rau kev ruaj ntseg, kev nyab xeeb, thiab kev siv hluav taws xob xa mus. Ntawm cov xwm txheej no, "txawm tias siv roj insulating" yog ib qho ntawm qhov tseem ceeb ntawm kev faib cov transformers.

 

Tsab ntawv xov xwm no muab cov ncauj lus kom ntxaws txog cov yam ntxwv tseem ceeb, daim ntawv thov scenarios, qhov sib txawv tseem ceeb, thiab kev xaiv logic rau roj -immersed thiab qhuav- hom transformers, muab kev cob qhia rau kev tsim hluav taws xob engineering tsim thiab xaiv cov khoom siv.

 

1. Roj-immersed Transformer yog dab tsi?

Cov roj-immersed transformer (tseem hu ua roj-filled transformer) yog cov khoom siv hluav taws xob ntau tshaj plaws hauv cov tshuab hluav taws xob. Nws lub hauv paus tsim muaj tag nrho rau hauv lub transformer cov khoom tseem ceeb -thaum winding, theem nrab winding, thiab core- nyob rau hauv insulating roj, uas ua hauj lwm ob qho tseem ceeb functions.

Raws li cov qauv, cov roj-immersed transformers feem ntau muaj cov windings, cov tub ntxhais, cov roj insulating, lub tank, thiab cov khoom siv pabcuam (xws li radiators thiab gas relays). Cov windings thiab cov tub ntxhais, ua lub hauv paus ntawm electromagnetic induction, yog immersed nyob rau hauv tshwj xeeb formulated insulating roj kom ntseeg tau rwb thaiv tsev tiv thaiv thiab tshav kub dissipation thaum lub sij hawm ua hauj lwm.

Insulating roj plays peb lub luag haujlwm tseem ceeb hauv cov roj-immersed transformers: Ua ntej, txias thiab cua sov dissipation- nws hloov cov cua sov uas tsim los ntawm cov windings thiab cov tub ntxhais thaum ua haujlwm rau lub tank phab ntsa lossis radiators ntawm thermal convection, tiv thaiv cov khoom puas los ntawm overheating.

 

Thib ob, kev tiv thaiv rwb thaiv tsev-leveraging cov roj zoo tshaj hluav taws xob rwb thaiv tsev cov khoom kom cais arcing txaus ntshai ntawm windings thiab nruab nrab windings thiab cov tub ntxhais, kom ntseeg tau tias muaj kev ruaj ntseg rwb thaiv tsev kev ua tau zoo.

 

Thib peb, nws ua kom muaj kev ruaj ntseg. High-cov roj insulating zoo muaj cov tshuaj lom neeg ruaj khov zoo, ua kom ntev - lub sijhawm ua haujlwm ruaj khov nyob rau hauv siab - kub thiab siab - cov kev mob siab, yog li txuas ntxiv lub neej kev pab cuam lub neej.

 

Puas muaj cov transformers uas tsis siv roj?

Cov lus teb yog yog. Dhau li ntawm cov roj-immersed transformers, qhuav- hom transformers yog cov roj ntau tshaj plaws - dawb variant. Lawv cov yam ntxwv tseem ceeb yog kev siv cov khoom siv insulating es tsis txhob siv cov roj insulating, tso siab rau huab cua ncig kom txias. Qhov no tshem tawm tag nrho ib puag ncig thiab kev nyab xeeb kev pheej hmoo cuam tshuam nrog roj to.

Cov yam ntxwv tseem ceeb ntawm qhuav- hom transformers tuaj yeem sau tau raws li hauv qab no:

• Txoj kev ua kom txias:Feem ntau tso siab rau lub ntuj cua convection lossis yuam cua txias, tshem tawm qhov xav tau ntxiv cov roj ncig thiab ua rau cov qauv yooj yim;
