Cov roj twg yog siv hauv gis?

Lub thawj roj siv nyob rau hauvGIS (roj-insulated Switchgear)yogSulphur hexafluoride (sf₆).

Ntawm no yog kev tawg ntawm vim li cas SF₆ siv thiab lwm cov roj ntsha:

Sulphur hexafluoride (sf₆):

Vim li cas nws yog qhov tseem ceeb:Sf₆ muaj tshwj xeebDielectric lub zog(txog 3 lub sij hawm siab dua huab cua ntawm tib lub siab), ua rau nws muaj txiaj ntsig zoo kawg nyob hauv cov gis-voltive gis enc.} Nws kuj tau ua tau zoo heevarc-quenchingcov khoom, qhov tseem ceeb rau kev nyab xeeb cuam tshuam kev cuam tshuam siab thaum hloov chaw lossis ua yuam kev .

Qhov Zoo:Ua rau ntau cov compact hloov cov qauv tsim piv rau cov khoom siv insulated, thiab muab cov chaw nyob ruaj khov nyob rau hauv ib txwm muaj .

Loj Duav:Sf₆ yog ib qhoTsis tshua muaj pes tsawg lub zog tsev cog khoom roj (GHG){{0 {}} nws muaj kev sov ntiaj teb muaj peev xwm (GWP)23,500 npaug ntau dua co₂Tshaj li {100- xyoo lub xyoo, thiab nws muaj lub neej ntev heev (txog 3,200 xyoo) {} {{{}}}

Sf₆ roj mixtures:

Txhawm rau kom txo cov kev cuam tshuam ib puag ncig thaum tswj kev ua tau zoo, sib xyaw ua ke ntawm cov pa roj av - nitrogen - nus, tshwj xeeb yog nyob rau hauv cov ntawv thov voltage lossis tshwj xeeb.

Cov mixtures dilute sf₆ cov ntsiab lus, txo qis zuag qhia tag nrho gwp ntawm insulating lub zog ua kom tiav kom ua tiav tib lub df₆ .

Lwm Txoj Kev "SF₆-dawb" Gases:

Vim tias qhov kev txhawj xeeb ib puag ncig ib puag ncig SF₆, cov kev tshawb fawb muaj tseeb thiab cov kev hloov kho tsis tau nrog ntau dua qis dua GWP {}} Cov no tau nce tuaj:

giv (ntsuab roj rau daim phiaj):Sib xyaw ua ke raws li3m novec ™ 4710 kua dej(fluoronitrile) thiab coo . nws muaj lub gwp ntawm tsawg dua 1 thiab ua yeeb yam zoo li cov gis puv nrog gin .

AirPlus ™:ABB cov kev xaiv, feem ntau ua ke sib xyaw ua rawsC₅-Fluoroketonethiab buffers zoo li huab cua lossis cole / n .}}}}} tseem muaj gwp tsawg heev (<1).

Novec ™ 5110 Insulating Roj (3M):Cov roj fluoronitrile-based roj siv hauv kev sib xyaw, zoo ib yam li g³ .

Ntshiab nitrogen (n₂) lossis qhuav cua:Qee zaum siv nyob rau hauv qis dua voltage gis lossis cov kev sib tw tshwj xeeb uas lawv xav tau cov khoom siv rau ib puag ncig thiab cov kev xaiv ntau dua .

Hauv cov ntsiab lus:

Sf₆ tseem muaj cov roj uas tseem ceeb tshaj plawsnyob rau hauv uas twb muaj lawm thiab ntau gis tshiab txhim kho vim nws txoj kev ua haujlwm tsis sib xws .

Cov Kev Cai Ib Puag Ncig (F-Roj Cov Kev Cai hauv EU, thiab lwm yam.}}}) yog tsav tsheb nrawm nrawmrauSF₆-DAWB DAWBnyiamGP (NOVEC ™ ™4710 + co)thiabAirplus ™ (C₅ FK + AIR / COUND)rau cov kev teeb tsa tshiab, tshwj xeeb yog nyob hauv thaj chaw nrog nruj ghg tswj .

SFO Mixturesyog qhov kev hloov pauv kev hloov pauv txo GWP cuam tshuam .

Nitrogen lossis huab cuayog siv qhov kev ua tau zoo uas yuav tsum tau ua tiav, feem ntau ntawm qis dua voltages .

Yog li, thaum cov lus teb yog overwhelminglySulphur hexafluoride (sf₆), cov toj roob hauv pes tau nquag nce zuj zus ntawm cov neeg ua haujlwm ib puag ncig .
