Daim ntawv thov ib puag ncig ntawm daim ntawv-Sheathed Hlau: Sib txuam Scenarios Raws li rwb thaiv tsev thiab cov yam ntxwv thermal
Jan 22, 2026| Daim ntawv- sheathed hlau, ib tug winding hlau nrog ib tug hlau conductor core, ib tug txheej insulating ntawv sheath, thiab ib tug impregnation kev kho mob, muaj zoo heev applicability nyob rau hauv ntau yam ib puag ncig tshwj xeeb vim nws tshwj xeeb hluav taws xob thiab thermal zog. Nws lub hom phiaj tsim thiab cov yam ntxwv ntawm cov khoom ua rau nws tshwj xeeb tshaj yog haum rau cov ntawv thov uas yuav tsum tau muaj kev ntseeg siab ntawm rwb thaiv tsev, kev tswj xyuas thermal zoo, thiab qee qhov kev muaj peev xwm ntawm cov neeg kho tshuab buffering. Nws feem ntau pom muaj nyob rau hauv lub hwj chim transformers, reactors, ntsuas transformers, thiab loj thiab nruab nrab- loj-voltage motors.
Ua ntej, daim ntawv -cov hlau sheathed ua tau zoo tshwj xeeb hauv cov roj- qhov chaw nyob rau hauv qhov chaw. Tom qab kev kho mob nrog ib tug tshwj xeeb impregnating tus neeg sawv cev, cov ntaub ntawv insulating tsim ib tug nruj kev sib raug zoo ib tug txheej txheem rwb thaiv tsev nrog cov ntxhia roj los yog hluavtaws insulating roj, zoo suppressing ib feem paug thiab ncua thermal aging. Yog li ntawd, daim ntawv- sheathed hlau yog feem ntau siv nyob rau hauv windings ntawm cov roj-immersed fais fab transformers, roj-immersed reactors, thiab siab-voltage instrument transformers siv lub siab dielectric zog thiab thermal stability ntawm cov roj-paper composite qauv, kom muaj kev ruaj ntseg margin lub sij hawm ntev.
Qhov thib ob, daim ntawv- sheathed hlau kuj muaj qhov zoo nyob rau hauv siab -kub khov kho- lub xeev kev ua haujlwm ib puag ncig. Siv high-cov ntaub ntawv insulating kub thiab cua sov-cov tshuaj tiv thaiv impregnating, ntawv-cov xov hlau insulated muaj cov khoom siv hluav taws xob ruaj khov thiab cov khoom siv hluav taws xob zoo nyob rau hauv qhov kub thiab txias, ua rau lawv tsim nyog rau cov ntawv thov uas xav tau ntev - lub sij hawm ua haujlwm kub, xws li transformers rau industrial furnaces, locomotive thiab loj traction.
Hauv siab-voltage thiab ultra-siab-voltage fais fab kis tau tus mob, lub teeb hluav taws xob sib faib thiab txhim khu kev qha interlayer rwb thaiv tsev ntawm daim ntawv-insulated xov hlau ua rau lawv nyiam cov khoom siv rau converter transformers thiab ultra-siab-voltage fais fab transformer windings. Cov roj-cov ntaub ntawv sib xyaw ua tau zoo tiv taus siab -amplitude AC thiab DC hluav taws xob teb, txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm rwb thaiv tsev thiab ua kom muaj kev nyab xeeb thiab ruaj khov ntawm daim phiaj hluav taws xob.
Tsis tas li ntawd, daim ntawv- cov xov hlau insulated muaj qee yam yuav tsum tau hais txog kev huv ntawm ib puag ncig thiab av noo. Txawm hais tias impregnation ho txhim kho cov dej tsis zoo, hauv av los yog condensation -ib puag ncig, lub tank ntim roj lossis roj qhuav tseem tsim nyog los tiv thaiv kev ya raws thiab kev ua haujlwm tsis muaj zog ntawm rwb thaiv tsev. Nyob rau hauv ib puag ncig uas muaj corrosive gases los yog plua plav, ntxiv txheej txheej tiv thaiv los yog siv cov corrosion-cov tshuaj tiv thaiv impregnating yuav tsum tau ntxiv kom ntev kev pab cuam lub neej.
Zuag qhia tag nrho, daim ntawv- insulated hlau yog haum rau hnyav thiab tswj ib puag ncig xws li roj immersion, kub kub ruaj khov, high voltage thiab ultra-high voltage. Nws cov txiaj ntsig zoo ntawm cov rwb thaiv tsev txhim khu kev qha, kev tiv thaiv tshav kub thiab kev ua haujlwm ntev thiab kev sib xyaw ua ke ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov windings tseem ceeb ntawm lub zog loj thiab cov khoom siv. Txawm li cas los xij, kev tiv thaiv ib puag ncig thiab kev saib xyuas cov tswv yim yuav tsum tau txiav txim siab tag nrho hauv kev tsim thiab siv los xyuas kom meej tias nws qhov kev ua tau zoo tuaj yeem ua tiav tsis tu ncua.
