Txheej txheem cej luam
Transformer bushing yog ib qho khoom siv hluav taws xob tseem ceeb uas pab txhawb kev sib txuas ntawm cov hluav taws xob siab thiab tsis tshua muaj hluav taws xob coj los ntawm hauv lub tshuab hluav taws xob mus rau sab nrauv ntawm cov roj tank. Nws yog tsim los nrog ib theem ntawm cov hluav taws xob muaj zog thiab muaj cov neeg kho tshuab muaj zog txaus los tiv thaiv ntau yam kev ntxhov siab. Kev khiav hauj lwm tam sim no ntawm lub casing yog ib qho tseem ceeb uas cuam tshuam rau kev xaiv ntawm qhov chaw hla ntu ntawm qhov kev coj ua, nrog rau tag nrho cov qauv ntawm lub connector.
Lub casing ntawm transformer bushing feem ntau yog tsim los ntawm cov ntaub ntawv xws li tooj dag, porcelain fwj, thiab epoxy resin. Cov ntaub ntawv no raug xaiv rau lawv cov khoom siv hluav taws xob zoo tshaj thiab muaj zog txhua yam, uas ua rau cov bushing tuaj yeem tiv taus ib puag ncig ntuj thiab tiv thaiv tshuaj lom neeg corrosion. Kev suav nrog lub tes tsho porcelain zoo nyob rau hauv tus tsim muab ib txheej ntxiv ntawm kev tiv thaiv rwb thaiv tsev, yog li ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov hluav taws xob tam sim no. Ceramic bushing yog dav siv nyob rau hauv lub hwj chim transformers, tis transformers, thiab ib tug dav array ntawm high-voltage hluav taws xob khoom. Raws li ib qho kev xaiv zoo tshaj plaws rau kev sib txuas cables thiab transformers, lub transformer bushing zoo tiv thaiv cov xau ntawm transformer roj. Nws kuj ua raws li kev tiv thaiv ib puag ncig ib puag ncig, xws li ya raws, plua plav, thiab lwm yam khoom corrosive, yog li tswj kev ncaj ncees thiab kev ua haujlwm ntawm cov hluav taws xob.
Cov xwm txheej ntawm kev siv
* Ambient kub:-45 degrees rau +40 degrees.
* Qhov siab:hom casing zoo tib yam tsis pub tshaj 1000 meters, txhim khu kev qha thiab anti-pollution hom casing tsis tshaj 2500 meters.
* Transformer bushingyog haum rau tej thaj chaw muaj kuab paug, anti-pollution type casing yog haum rau hnyav hnyav.
* Lub kaum ntse ntse:ntsug lossis inclined Lub kaum sab xis tsis tshaj 30 degrees.
