High-voltage bushing yog hais txog ib qho khoom siv uas tso cai rau ib lossis ob peb tus neeg xyuas kom dhau los ntawm kev faib tawm xws li cov phab ntsa lossis cov thawv rau rwb thaiv tsev thiab kev txhawb nqa, thiab yog ib qho tseem ceeb hauv cov tshuab hluav taws xob.Nyob rau hauv cov txheej txheem ntawm kev tsim, kev thauj mus los thiab kev saib xyuas, high-voltage bushings yuav muaj qhov tsis xws luag vim muaj ntau yam laj thawj;Thaum lub sijhawm ua haujlwm ntev, lawv raug cuam tshuam los ntawm cov teebmeem ntawm hluav taws xob thiab cov neeg xyuas pib cua sov, kev puas tsuaj thiab tshuaj lom neeg corrosion, thiab atmospheric tej yam kev mob.Tseem yuav muaj qhov tsis xws luag maj mam.
High-voltage bushings yog siv rau hauv av rwb thaiv tsev ntawm cov khoom siv hluav taws xob nkag thiab tawm xws li transformers, reactors, thiab Circuit Court breakers, thiab high-voltage circuits dhau los ntawm phab ntsa.Muaj peb hom high voltage bushing: ib dielectric bushing, composite dielectric bushing thiab capacitive bushing.Lub ntsiab rwb thaiv tsev ntawm lub capacitive bushing yog tsim los ntawm coaxial cylindrical series capacitor bank tsim los ntawm winding txheej insulating cov ntaub ntawv thiab ntawv ci hlau electrodes alternately ntawm tus pas nrig conductive.Raws li cov ntaub ntawv insulating sib txawv, nws muab faib ua daim ntawv gummed thiab oiled ntawv capacitive bushing.110kV thiab saum toj no transformer high-voltage bushings feem ntau yog roj-ntawvhom capacitor;Nws yog tsim los ntawm cov khoom siv hluav taws xob, cov khoom siv roj cia, lub tes tsho porcelain sab saud, lub tes tsho porcelain qis, capacitor core, coj pas nrig, insulating roj, flange, thiab lub pob siab.
Thaum lub sij hawm ua hauj lwm ntawm high-voltage bushing, lub ntsiab rwb thaiv tsev yuav tsum tiv taus high voltage, thiab cov conductive ib feem yuav tsum dais loj tam sim no.Lub ntsiab faults yog tsis zoo kev twb kev txuas ntawm sab hauv thiab sab nraud hluav taws xob connectors, damp thiab deterioration ntawm bushing rwb thaiv tsev, tsis muaj roj nyob rau hauv bushing, ib feem ntawm lub capacitor core thiab tso tawm ntawm qhov kawg screen rau hauv av, thiab lwm yam.
Transformer bushing yog ib qho khoom siv hluav taws xob uas ua rau cov xaim hluav taws xob siab ntawm lub transformer winding mus rau sab nraud ntawm cov roj tank, thiab ua haujlwm raws li cov khoom siv hluav taws xob thiab cov rwb thaiv tsev hauv av.Thaum lub sijhawm ua haujlwm ntawm lub tshuab hloov pauv, cov khoom thauj tam sim no dhau los ntawm lub sijhawm ntev, thiab qhov luv luv tam sim no dhau los ntawm thaum lub caij luv luv tshwm sim sab nraum lub tshuab hloov pauv.
Yog li ntawd, transformer bushing muaj cov hauv qab no yuav tsum tau:
Yuav tsum muaj lub zog hluav taws xob thiab muaj zog txhua yam txaus;
Nws yuav tsum muaj thermal stability zoo thiab muaj peev xwm tiv taus tam sim ntawd overheating thaum luv luv;me me nyob rau hauv cov duab, me me nyob rau hauv loj, thiab zoo nyob rau hauv sealing kev ua tau zoo.
Kev faib tawm
High-voltage bushings tuaj yeem muab faib ua roj puv bushings thiab capacitive bushings.
Cov kabntawvnyob rau hauv cov roj puv bushing zoo ib yam li cov phaj vaj huam sib luag hauv lub capacitive bushing.Lub capacitor tub ntxhais nyob rau hauv lub capacitive bushing yog ib tug series ntawm coaxial cylindrical capacitors, thiab nyob rau hauv cov roj puv bushing, lub dielectric tas li ntawm daim ntawv insulating yog siab tshaj li ntawm cov roj, uas yuav txo tau lub zog teb nyob rau ntawd.
Roj puv bushings tuaj yeem muab faib ua ib qho roj sib txawv thiab ntau cov roj sib txawv bushings, thiab capacitive bushings tuaj yeem muab faib ua gummed thiab oiled ntawv bushings.
Lub tes tsho yog siv thaum cov neeg nqa khoom tam sim no yuav tsum dhau los ntawm cov ntaub thaiv hlau lossis phab ntsa ntawm cov peev txheej sib txawv.Raws li lub sijhawm siv tau no, bushings tuaj yeem muab faib ua transformer bushings, bushings rau keyboards lossis ua ke cov khoom siv hluav taws xob, thiab phab ntsa bushings.Rau qhov kev npaj "plug-in" electrode no, cov hluav taws xob hluav taws xob yog qhov muaj zog heev ntawm ntug ntawm cov electrode sab nraud (xws li nruab nrab flange ntawm bushing), qhov twg cov paug feem ntau pib.
Kev siv thiab cov yam ntxwv ntawm casing
High-voltage bushings yog siv rau high-voltage conductors kom dhau los ntawm partitions uas muaj peev xwm sib txawv (xws li phab ntsa thiab hlau casings ntawm cov khoom siv hluav taws xob) rau rwb thaiv tsev thiab kev txhawb nqa.Vim tias qhov tsis sib xws ntawm cov hluav taws xob hluav taws xob hauv lub bushing, tshwj xeeb tshaj yog cov concentrated hluav taws xob teb ntawm ntug ntawm nruab nrab flange, nws yog ib qho yooj yim ua rau ntog tawm.Cov txheej txheem rwb thaiv tsev sab hauv ntawm bushing nrog qib siab dua voltage yog qhov nyuaj dua, feem ntau siv cov ntaub ntawv insulating ua ke, thiab muaj teeb meem xws li kev tso tawm ib nrab.Yog li ntawd, kev sim thiab tshuaj xyuas ntawm cov casing yuav tsum tau ntxiv dag zog.
