Dab tsi yog lub siab-voltage bushing?

May 15, 2025

Tso lus

Lub high-voltage bushing yog ib qho cuab yeej rau ib lossis ntau qhov kev faib tawm high-voltage dhau los (xws li ib lub phab ntsa, hlau casing ntawm cov khoom siv fais fab, thiab lwm yam). Nws ua lub luag haujlwm tseem ceeb hauv rwb thaiv tsev thiab kev txhawb nqa hauv lub zog hluav taws xob. Cov hauv qab no yog kev qhia rau koj:

Cov Txheej Txheem Muaj Zog

Cov qauv sab nraud: suav nrog cov chaw nres tsheb ciav hlau, los ntawm cov dej nag, cov roj tawm hauv ncoo, cov roj txuas ntxiv, sib npaug pob, thiab lwm yam.

Sab hauv cov qauv: Ntau-txheej cylindricrical capacmorts tsim tau ntawm cov roj-impregnated cable electrode thiab lub porcelainin ib feem yog siv raws li cov rwb thaiv tsev sab nraud thiab lub thawv ntawm transformer roj.

Kev faib

Los ntawm kev siv, nws tuaj yeem muab faib ua phab ntsa bushing, thiab lwm yam hluav taws xob cov hlau los ntawm cov phab hlau, partitions, lossis av qeeg. Lawv tau siv dav hauv cov hluav taws xob siab xws li cov nroj tsuag hluav taws xob thiab cov chaw sib txuas uas cuam tshuam nrog hluav taws xob sib txuas thiab hluav taws xob rwb thaiv tsev ntawm cov chaw phab ntsa. Transformer bushings txhuas cov hlau hluav taws xob hauv lub tshuab hluav taws xob sab hauv lub tshuab roj av, ua haujlwm li ob lub xov hlau txhuas thiab kho cov hlau ua txhuas. GIS cov bushings yog siv nyob rau hauv cov roj-insulated hlau-insulated hloov hloov pauv (gis) kom ua tiav kev twb kev txuas thiab rwb thaiv tsev ntawm high-voltage belterorsors thiab sab nraud.

Raws li cov ntaub ntawv rwb thaiv tsev thiab cov txheej txheem rwb thaiv tsev, lawv tuaj yeem faib ua cov khoom siv rwb thaiv tsev (cov khoom siv capacitor Capacitor bushings yog cov nquag siv ntau yam tam sim no-voltage thiab ultra-high-voltage Systems. Lawv muaj ib qho kev sib txuas hauv nruab nrab (cov chaw sib txuas, cov hlau sab nraud, thiab lwm yam.

Raws li cov qauv tam sim no, lub bushing ntawm cov roj-daim ntawv capacitor tuaj yeem faib ua hom cable-xov thiab conduit-threading. Ntawm lawv, conduit-xov xov yuav muab faib ua cov hom ncaj qha thiab cov pas nrig sib txuas raws li kev sib txuas ntawm cov roj davhlau ya nyob twg thiab bushing. Cable-threading-hom thiab ncaj qha conduit-threading-hom bushings yog dav siv nyob rau hauv cov fais fab system.

Kev Ua Tau Zoo Yuav Tsum Tau

Lub zog hluav taws xob: nws yuav tsum muaj lub zog hluav taws xob teev thiab muaj peev xwm tiv thaiv lub siab ultrasonic yuav tsis muaj qhov hluav taws xob luv los yog muaj hluav taws xob sib zog thaum lub zog hluav taws xob. Piv txwv li, hauv UHV kis cov kab ke, cov-voltage bushing yuav tsum tau withstand tsis tshua muaj hluav taws xob, thiab lub zog hluav taws xob yuav tsum ua tiav cov qauv nruj.

Mechanical zog: nws yuav tsum muaj lub zog siv tau muaj zog kom muaj kev ntxhov siab xws li nws tus kheej lub cev hnyav, thiab hluav taws xob yuav tsis yog deformed lossis puas thaum lub sijhawm ua haujlwm.

Thermal Stability: Nws muaj qhov zoo thermal ruaj khov thiab tuaj yeem tiv thaiv instantaneous overheating thaum lub sij hawm luv luv hluav taws xob txhawm rau thaiv kev ua haujlwm rwb thaiv tsev ua tsis tau kev ua haujlwm. Thaum ib qho kev ua yuam kev luv-taws-tshwm sim hauv lub transformer, lub bushing yuav dhau ib lub tsheb luv luv loj dua thiab tsim kom muaj cua sov ntau. Zoo thermal ruaj khov tuaj yeem ua kom ntseeg tau tias lub bushing tseem tuaj yeem ua haujlwm ib txwm nyob hauv cov xwm txheej no.

Sealing kev ua tau: Txais yuav cov qauv seading, xws li ntim roj hmab lossis tshuaj tiv thaiv roj hmab lossis kom paub meej tias cov roj insulating sab hauv lub transformer yuav tsis xau rau sab nraud. Nyob rau tib lub sijhawm, cov roj hloov hluav taws xob sab hauv lub bushing yog ib qho kev ywj pheej, uas tsis cuam tshuam los ntawm cov cua kom muaj kev ruaj ntseg ntawm cov kev ua haujlwm rwb thaiv tsev.

Lwm yam kev ua tau zoo: nws yuav tsum muaj cov yam ntxwv ntawm me me, lub teeb yuag, cov khoom siv yooj yim, thiab cov kev siv yooj yim thiab txo cov nqi.

Sib Xws Tsim

Kev Ntsuas Cov Pob: Tus Tsov tus tw ntawm lub bushing yog nruab nrog lub rwb thaiv tsev qhov chaw faib khoom, uas yog siv hluav taws xob sib tsoo thiab qhov chaw ua haujlwm hluav taws xob thiab kev nyab xeeb ntawm lub bushing.

Roj hauv ncoo: Lub taub hau ntawm lub taub hau yog nruab nrog roj hauv ncoo hloov los ntawm qhov kub ntawm lub siab yog qhov pub dawb los ntawm lub siab loj. Cov roj ntsuas ntawm cov roj hauv ncoo tuaj yeem saib xyuas cov roj qib thaum ua haujlwm kom ntseeg tau tias cov roj qib sab hauv yog qhov qub.

Xaus tshuaj ntsuam: Lub me me bushing coj tawm ntawm qhov kawg screen ntawm cov roj-ntawv censoring dielectric bushing chant thiab hloov pauv ib nrab ntawm kev kuaj ntshav. Me me bushings yuav tsum tau nyob kaj siab thaum lub sijhawm ua haujlwm ib txwm muaj. Thaum tshem tawm lub tsho me me ntawm lub vijtsam tas los, nws yog ib qho tsim nyog los tiv thaiv tus coj cov hlau me me lossis puas rau cov hmoov txhuas daim ntawv ntawm lub phaj.
