Hauv cov tshuab hluav taws xob niaj hnub no, kev nyab xeeb kev sib kis thiab kev faib hluav taws xob cia siab rau ntau yam tseem ceeb ua haujlwm sib haum xeeb. Ntawm cov no, High Voltage Porcelain Bushing yog ib qho khoom siv hluav taws xob tsis tseem ceeb uas ua kom muaj kev ntseeg siab ntawm kev hloov pauv, hloov pauv, thiab lwm yam khoom siv hluav taws xob siab. Tsab ntawv xov xwm no muab cov lus qhia dav dav ntawm cov khoom siv hluav taws xob porcelain bushings, lawv cov qauv, kev ua haujlwm, kev ua haujlwm tsis zoo, thiab kev siv, ua qhov kev paub zoo tshaj plaws rau cov kws tshaj lij kev lag luam thiab cov neeg koom nrog hauv lub ntiaj teb fais fab kev lag luam.
A High Voltage Porcelain Bushingyog ib qho khoom siv insulating siv nyob rau hauv siab -voltage fais fab tshuab kom dhau cov conductors los ntawm cov teeb meem xws li phab ntsa, tank enclosures, los yog hlau casings, thaum tuav tag nrho cov hluav taws xob rwb thaiv tsev ntawm tus neeg xyuas pib thiab grounded barrier. Nws yog ib qho tseem ceeb tivthaiv uas ua rau muaj kev nyab xeeb nkag thiab tawm ntawm kev sib txuas hluav taws xob hauv cov khoom siv hluav taws xob, hluav taws xob hluav taws xob, thiab lwm yam khoom siv hluav taws xob siab -
Cov qauv thiab cov khoom siv
Lub high voltage porcelain bushing feem ntau muaj peb yam tseem ceeb:
| Cheebtsam | Kev piav qhia |
| Porcelain Insulator | Ua los ntawm siab -lub zog hluav taws xob porcelain raug rho tawm haujlwm ntawm qhov kub thiab txias, muab cov khoom siv rwb thaiv tsev zoo thiab lub zog txhua yam |
| Hlau Flange | Siv rau mounting thiab ruaj lub bushing, muab kev sib txuas interfaces nrog cov khoom siv sab nraud; feem ntau yog ua los ntawm stainless hlau los yog galvanized hlau |
| Tus coj | Lub central conducting pas nrig los yog lub raj uas cov hluav taws xob tam sim no hla |
Cov khoom tseem ceeb:Cov plooj (porcelain) lub cev nta lub ntsej muag glazed lossis tiv thaiv -kev ua pa phem txheej txheej txheej txheej los txhim kho kev sib kis thiab tiv thaiv huab cua. Sealing Cheebtsam feem ntau siv cov laus- cov roj hmab resistant gaskets los yog epoxy seals los xyuas kom meej huab cua- nruj thiab roj- nruj kev ua haujlwm .
Kev Ua Haujlwm thiab Lub Luag Haujlwm
Lub high voltage porcelain bushing pab ntau yam tseem ceeb hauv cov tshuab fais fab:
1. Hluav taws xob rwb thaiv tsev
Lub luag haujlwm tseem ceeb yog los tiv thaiv hluav taws xob tiv tauj nruab nrab ntawm qhov siab -voltage conductor thiab ib puag ncig ib puag ncig (xws li phab ntsa, hauv av, lossis hauv av enclosures), ua kom muaj kev nyab xeeb ntawm lub zog hluav taws xob.
2. Mechanical Support
Lub bushing bears qhov hnyav ntawm tus neeg xyuas pib thiab cov neeg kho tshuab sab nraud, tswj tus neeg xyuas pib txoj haujlwm ruaj khov thiab tiv thaiv hluav taws xob hluav taws xob tsim tawm thaum lub sijhawm luv luv.
3. Tiv thaiv - pa phem Flashover
Muaj ntau lub tshuab hluav taws xob porcelain bushings muaj kev tiv thaiv- qauv tsim muaj kuab paug (xws li cov chaw loj thiab me me / lub kaus) uas txo cov khoom paug ntawm cov khoom siv hluav taws xob, txhim kho kev ua haujlwm rwb thaiv tsev hauv qhov chaw muaj kuab paug.
Manufacturing Standards
High voltage porcelain bushings yog tsim, tsim, thiab kuaj raws li ntau yam thoob ntiaj teb thiab lub teb chaws tus qauv:
TS EN 60137- Cov txheej txheem thoob ntiaj teb rau bushings rau alternating voltages saum 1,000 V
ANSI- American National Standards Institute cov qauv
DIN- Lub koom haum German rau Standardization qauv
GB/T 12944-2011- Suav lub teb chaws tus qauv "High-voltage los ntawm- phab ntsa porcelain bushings"
Daim ntawv thov Scenario
High voltage porcelain bushings yog dav siv nyob rau hauv ntau lub hwj chim chaw:
| Daim ntawv thov | Kev piav qhia | |
|---|---|---|
| Hloov pauv | Rau txuas transformer windings rau sab nraud fais fab kab | |
| Switchgear | Rau rwb thaiv tsev hauv Circuit Court breakers thiab lwm yam khoom siv hloov pauv | |
| Substations | Rau kev sib txuas siab - cov khoom siv hluav taws xob nrog cov kab sab nraud, lossis dhau los ntawm lub tsev phab ntsa thiab cov txee enclosures [citation: neeg siv] | |
| Fais fab kis Systems | Rau kev sib kis thiab kev faib hluav taws xob |
- Thaum xaiv lub high voltage porcelain bushing, cov hauv qab no yog qhov tseem ceeb:
- Voltage thiab Tam sim no Ratings: Yuav tsum ua raws li qhov system qhov ntsuas hluav taws xob thiab qhov xav tau tam sim no.
- Ib puag ncig tej yam kev mob: Rau cov cheeb tsam uas muaj kuab paug siab los yog ib puag ncig ntug hiav txwv dej, xaiv los tiv thaiv - pa phem los yog ntsev- hom pos huab resistant nrog txaus creepage nrug .
- Mechanical Loads: Xav txog qhov hnyav ntawm tus neeg xyuas pib thiab qhov luv luv -circuit electromagnetic rog; cov hom kev txhawb zog tuaj yeem xav tau.
- Mounting Interface: Xyuas kom tseeb tias qhov flange loj, txoj kev sib khi, thiab lub tank qhov ntev yog sib xws nrog cov khoom siv.
- Kev Ua Raws Cai: Xyuas kom cov bushing ua tau raws li kev siv thoob ntiaj teb (IEC, ANSI, DIN) lossis hauv zos (GB) cov qauv.
