Hauv kev hloov pauv thoob ntiaj teb mus rau lub zog ruaj khov, kev lag luam hluav taws xob ntsib ib qho kev sib tw tshwj xeeb: ntsuas qhov tsis sib xws ntawm rwb thaiv tsev ua haujlwm ntawmGas Insulated Switchgear (GIS)nrog lub luag haujlwm hnyav ib puag ncig ntawm kev tswj hwmSulfur Hexafluoride (SF6).
Nrog rau Lub Ntiaj Teb Warming Potential (GWP) ntawm 23,900 npaug ntawm CO2CO2, txawm tias qhov xaim me tshaj plaws tsis yog qhov kev ua tsis tiav lawm xwb - nws yog ib qho kev lav phib xaub loj thiab kev tswj hwm.
1. Tshaj li kev tshem tawm cua: Lub luag haujlwm tseem ceeb ntawm lub tshuab nqus tsev
Rau ib tus kws tshaj lij junior lossis senior engineer, "Commissioning Phase" yog qhov kev txiav txim siab lub neej ntawm GIS. Kev coj ua qauv xav kom lub thawv ntim khoom nqus mus rau hauv qab133 hli (1 mbar)ua ntej sau nrog roj.
Tab sis vim li cas qhov kev txiav txim siab no tseem ceeb heev?
Moisture yog tus yeeb ncuab:Residual cua muaj noo noo. Nyob rau hauv lub tshav kub ntawm ib tug hluav taws xob arc, dej reacts nrog SF6 rau daim ntawvHydrofluoric Acid (HF), uas tuaj yeem etch los ntawm resin insulators hauv lub hlis.
Oxygen Displacement:Kev tshem tawm cov pa oxygen tiv thaiv kev tsim cov tshuaj lom los ntawm - cov khoom, ua kom lub sij hawm ntev - tshuaj stability ntawm lub rwb thaiv tsev nruab nrab.
2. Lub "Vaj Huam Sib Luag Economy" ntawm SF6: Rov qab thiab Purification
Niaj hnubSF6 Gas Recovery Unitstau hloov zuj zus los ntawm qhov yooj yim "sucking machines" mus rau hauv cov khoom siv hluav taws xob zoo tshaj plaws. Hnub no lub siab- cov khoom siv kawg ua ntau dua li cia li khaws cov roj; lawv uaDeep Purification.
Los ntawm kev sib koom ua ke ntau-theem pom- suav nrog molecular sieves kom tshem tawm SO2 thiab HF- cov units no tuaj yeem rov qab "siv" roj rau99.9% ntshiabUa raws li IEC 60480 tus qauv. Rau ib tus neeg saib xyuas kev siv hluav taws xob, qhov no sawv cev rau ROI tseem ceeb los ntawm kev txo qhov kev xav tau ntawm cov khoom siv roj tshiab kim thaum ua tiav "Green Substation" txoj haujlwm.
3. Cov Txheej Txheem Txheej Txheem Tseem Ceeb rau xyoo 2026
Raws li daim phiaj kev ntseeg siab dhau los ua qhov tseem ceeb, pab pawg saib xyuas tab tom nrhiav rau peb qhov tshwj xeeb hauv lawv qhov kev rov qab los thiab lub tshuab nqus tsev vacuuming:
Roj -Compression Dawb:Xyuas kom zero cross- paug ntawm SF6 roj nrog lub twj tso kua mis lubricants.
Siab -Nqus Residual Pressure:Muaj peev xwm rov qab tau roj mus rau< 1 mbar, tawm hauv zero gas qab hauv cov khoom siv.
Digital Integration:Cov kev soj ntsuam ntse uas taug qab qhov tseeb kilos ntawm cov roj rov qab, pab hauv kev tshaj tawm cov pa roj carbon hneev taw.
Xaus: Engineering rau Kev Ntseeg thiab Sustainability
Ntawm[Wuhan Huayi], peb nkag siab tias GIS tsuas yog txhim khu kev qha raws li cov cuab yeej siv los tswj nws. Peb tiam tshiab ntawmIntegrated SF6 Recovery thiab Nqus Systemsyog tsim los muab cov engineers teb qhov tseeb lawv xav tau los tiv thaiv cov cuab tam thiab lub ntiaj teb.
Raws li kev lag luam txav mus rau "SF6-Free" lwm txoj hauv kev yav tom ntej, kev tuav thiab rov ua dua tshiab ntawm SF6 cov khoom lag luam uas twb muaj lawm tseem yog cov pab pawg saib xyuas muaj txiaj ntsig zoo tshaj plaws tuaj yeem ua hnub no.
