Gas Insulated Substation yog dab tsi?
Hais txog kev tsim hluav taws xob niaj hnub no, "Gas Insulated Substation" (GIS) yuav zoo li me ntsis kev.Tab sis kev paub txog GIS thev naus laus zis yog qhov tseem ceeb vim nws pab tswj thiab muab hluav taws xob zoo. Hauv tsab xov xwm no, peb yuav tham txog dab tsi Gas Insulated Substation yog dab tsi, nws ua haujlwm li cas, nws muaj txiaj ntsig zoo, thiab vim li cas nws thiaj li nrov hauv nroog.
Ua ntej peb nkag mus rau hauv GIS thev naus laus zis, cia peb nkag siab qee qhov tseem ceeb ntawm cov khoom siv hluav taws xob. Substations yog nyob rau hauv nruab nrab ntawm txhua lub hwj chim faib system. Lawv hloov qhov hluav taws xob los ntawm qhov siab mus rau qis lossis qis mus rau siab kom hluav taws xob tuaj yeem taug kev mus ntev thiab muab rau cov tsev thiab chaw ua haujlwm. Ib txwm substations siv cua -insulated switchgear rau qhov no.
Gas Insulated Substation yog ib yam ntawm cov chaw nres tsheb uas siv sulfur hexafluoride (SF6) gas rau rwb thaiv tsev ntawm nws cov khoom hluav taws xob. Hloov chaw ntawm kev siv cua rwb thaiv tsev, GIS thev naus laus zis tau ntim cov khoom siv hluav taws xob xws li cov hluav taws xob hluav taws xob thiab cov hloov hluav taws xob hauv lub thawv kaw uas muaj cov roj no. SF6 yog ib qho zoo heev insulator thiab tuaj yeem tiv thaiv hluav taws xob arcs thiab luv circuits.
Hauv GIS, SF6 roj yog siv los ua qhov nruab nrab insulating nyob ib ncig ntawm cov hluav taws xob nyob. Cov roj tau khaws cia hauv cov thawv hlau uas tiv thaiv nws los ntawm cov khoom sab nraud xws li huab cua thiab cov pa phem. Nws tuaj yeem txo qhov loj ntawm cov khoom siv thiab teeb tsa lub substation hauv tsev lossis hauv qhov chaw txwv, yog li nws tsim nyog rau cov nroog.
Gas-insulated substations muaj ntau yam zoo dua li cov pa pa-insulated substations. Cia peb saib qee qhov tseem ceeb:
Ib qho txiaj ntsig zoo tshaj plaws ntawm GIS thev naus laus zis yog qhov me me. Ib txwm substations xav tau ntau thaj av, uas nyuaj rau nrhiav tau nyob rau hauv cov neeg coob coob. Tab sis roj- insulated substations xav tau ntau qhov chaw me me, yog li lawv zoo rau cov nroog uas tsis muaj chaw ntau lossis av nqi ntau.
Piv nrog rau huab cua-insulated system, GIS muaj kev nyab xeeb thiab kev ntseeg tau zoo dua. Kev sib khi ib puag ncig tuaj yeem tiv thaiv kev nkag mus ntawm cov kab mob sab nraud rau cov khoom siv hluav taws xob, yog li txo qhov ua yuam kev thiab tsis ua haujlwm. Tsis tas li ntawd, SF6 roj siv rau kev rwb thaiv tsev tuaj yeem tiv thaiv hluav taws xob arcs thiab luv circuits.
Txij li thaum cov khoom siv hluav taws xob raug kaw hauv qhov chaw tswj hwm, cov pa roj- insulated substations xav tau kev saib xyuas tsawg dua piv rau cov huab cua- rwb thaiv tsev. SF6 roj tsis deteriorate nyob rau lub sij hawm, yog li muaj tsawg txaus ntshai ntawm qhov chaw tsis ua hauj lwm, uas txhais tau hais tias tsawg zaus koj yuav tsum tau xyuas lawv tsis tu ncua.
SF6 roj yog lub tsev cog khoom muaj zog, tab sis tag nrho ib puag ncig kev cuam tshuam ntawm GIS thev naus laus zis yuav tsawg dua li ntawm cov chaw ua haujlwm ib txwm muaj. Qhov no yog vim qhov tseeb tias nws yuav tsum muaj av tsawg thiab cov peev txheej vim nws me me thiab tsis xav tau kev saib xyuas ntau. Thiab tseem, cov neeg tsim khoom ntawm GIS yeej ib txwm sim los nrog lwm txoj hauv kev thiab txoj hauv kev zoo dua los ua kom GIS ntsuab.
Gas-sulated substations yog tshwj xeeb tshaj yog haum rau siv nyob rau hauv lub nroog thiab lwm qhov chaw uas tsis muaj chaw. Qee qhov piv txwv ntawm qhov twg GIS thev naus laus zis feem ntau siv:
Hauv cov nroog uas tsis muaj chaw seem rau thaj av, GIS thev naus laus zis tuaj yeem siv los faib hluav taws xob zoo yam tsis tas yuav muaj cov chaw nres tsheb loj.Cov chaw me me no tuaj yeem muab tso rau hauv lwm lub tsev lossis muab zais hauv av kom lawv tsis txhob ua rau lub nroog tsis zoo.
Cov chaw lag luam feem ntau xav tau hluav taws xob ntau los khiav lawv.Gas- insulated substations muab ib qho kev cia siab thiab kev daws teeb meem kom ua tau raws li cov kev xav tau ntawm lub zog thaum tswj kev ruaj ntseg thiab kev cia siab ntawm lub hwj chim.
Raws li peb txav mus rau qhov chaw siv hluav taws xob tauj dua tshiab, cov pa roj-cov chaw thaiv hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev siv cov thev naus laus zis no rau hauv daim phiaj.GIS thev naus laus zis yog hloov tau thiab txhim khu kev qha yog li nws yog qhov kev xaiv zoo rau kev sib txuas cua, hnub ci thiab lwm yam khoom siv hluav taws xob txuas ntxiv nrog lub zog uas twb muaj lawm.
Txawm hais tias Gas Insulated Substations muaj ntau qhov zoo, kuj tseem muaj qee qhov teeb meem thiab yam yuav tsum xav txog.
Thawj tus nqi ntawm cov roj insulated substation yuav ntau dua li ntawm cov pa cua insulated substation.Tab sis tus nqi no tuaj yeem them rov qab los ntawm kev txo qis rau kev yuav av thiab kev saib xyuas, thiab txhim kho kev ntseeg tau thiab kev ua haujlwm ntawm lub cev.
SF6 roj uas siv hauv GIS thev naus laus zis yog lub tsev cog khoom muaj zog. Txawm hais tias cov pa roj- insulated substations muaj cov qauv kaw uas tuaj yeem txo qhov muaj peev xwm ntawm cov pa tawm, peb tseem yuav tsum tau saib xyuas cov roj kom zoo thiab muab pov tseg kom zoo kom txo tau nws cov txiaj ntsig ntawm ib puag ncig. Txoj kev R&D txuas ntxiv tab tom sim nrhiav lwm cov roj insulating uas tsis muaj kev cuam tshuam ib puag ncig.
Nrog ntau thiab ntau lub nroog tau tsim, thiab qhov kev thov kom muaj kev vam khom hluav taws xob loj hlob, nws cia siab tias cov roj hluav taws xob hluav taws xob yuav muaj feem ntau dua los ua si yav tom ntej ntawm hluav taws xob infrastructure. Raws li thev naus laus zis txuas ntxiv mus thiab muaj kev tsom mus rau kev ruaj khov, GIS thev naus laus zis tuaj yeem dhau los ua qhov kev xaiv zoo dua rau kev faib hluav taws xob thoob plaws ntiaj teb. Gas insulated substations yog ib txoj hauv kev niaj hnub thiab muaj txiaj ntsig zoo los tswj thiab faib hluav taws xob, tshwj xeeb hauv cov nroog uas muaj chaw tsawg. Lawv yog cov me me, muaj kev nyab xeeb, thiab muaj kev vam meej, yog li lawv yog qhov zoo hloov pauv rau huab cua qub - insulated substations. Raws li peb tab tom nrhiav kom muaj kev ruaj khov thiab muaj txiaj ntsig zoo los muab lub zog, cov pa roj- insulated substations yeej yuav muaj feem tseem ceeb los ua qhov peb ua kom hluav taws xob ua haujlwm yav tom ntej.
