Gas insulated switchgear (GIS txee) yog ib qho khoom siv hluav taws xob siab heev uas tau siv dav hauv cov tshuab hluav taws xob niaj hnub no. Nws ua kom muaj kev ntseeg siab thiab kev nyab xeeb ntawm lub zog hluav taws xob los ntawm kev siv roj nrog lub zog rwb thaiv tsev siab thiab siab arc extinguishing peev xwm raws li cov rwb thaiv tsev thiab arc extinguishing nruab nrab. Piv nrog rau cov khoom cua-insulated, roj-insulated thiab khoom-insulated switchgear, roj-insulated switchgear muaj cov ntawv thov tshwj xeeb zoo thiab cov yam ntxwv hauv lub zog hluav taws xob.
I. Kev txhais thiab lub hauv paus ntsiab lus ua haujlwm
Cov roj hluav taws xob hluav taws xob hloov hluav taws xob yog tsim los ntawm cov hlau txuas nrog cov khoom sib txuas, uas yog nruab nrog cov hluav taws xob hluav taws xob, cov khoom siv hluav taws xob, cov hluav taws xob, cov hluav taws xob, cov khoom siv hluav taws xob, cov hloov hluav taws xob, cov hluav taws xob thiab lwm yam khoom siv. Qhov tseem ceeb yog siv cov pa roj xws li SF6 (sulfur hexafluoride) ua lub ntsiab insulating nruab nrab ntawm cov khoom nyob thiab hauv av hlau casing. SF6 roj muaj lub zog dielectric siab, siab thermal stability thiab zoo heev arc extinguishing kev ua tau zoo, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau GIS txee.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm GIS txee feem ntau yog nyob ntawm tus yam ntxwv ntawm SF6 roj. Nws siv SF6 gas ua ib qho insulator thiab arc extinguisher. Thaum muaj kev txhaum tshwm sim hauv Circuit Court, nws sai sai tua lub arc los ntawm ob lub tshuab: thermal cuam tshuam thiab dielectric cuam tshuam, ua kom ruaj khov ntawm lub zog hluav taws xob. Lub thermal cuam tshuam mechanism ua rau lub arc los ntawm kev hloov cov cua sov, ua rau nws tsis kam mus txog rau thaum tam sim no txo qis rau xoom thiab lub arc yog extinguished. Lub dielectric cuam tshuam mechanism absorbs dawb electrons los ntawm SF6 roj, tsub kom lub dielectric zog ntawm cov roj, thiab tiv thaiv lub arc los ntawm kev tawm tsam dua.
II. Lub ntsiab zoo
Gas-insulated switchgear muaj qhov zoo hauv qab no:
1. Ib puag ncig tus phooj ywg:
Gas-insulated switchgear siv SF6 roj ua ib qho nruab nrab insulating, uas yuav tsis ua phem rau ib puag ncig thiab ua tau raws li niaj hnub kev tiv thaiv ib puag ncig.
2. Muaj kev nyab xeeb thiab txhim khu kev qha:
GIS txee muaj kev ua haujlwm zoo rwb thaiv tsev thiab muaj zog arc extinguishing muaj peev xwm, uas tuaj yeem tiv thaiv kev sib tsoo luv luv thiab txhim kho kev ntseeg siab ntawm lub zog hluav taws xob.
3. Qhov chaw txuag:
Txij li thaum lub zog rwb thaiv tsev ntawm SF6 roj yog 3 npaug ntawm huab cua, qhov hluav taws xob tshem tawm ntawm lub txee GIS tau txo qis heev, thiab cov hneev taw kuj me me, uas yog tsim rau cov xwm txheej uas muaj qhov txwv.
4. Tsawg tus nqi tu:
Lub thawv ntim roj ntim rau hauv GIS txee tsis cuam tshuam los ntawm ib puag ncig, thiab tuaj yeem tswj tau qhov zoo tshaj plaws hluav taws xob qhov chaw, txo kev tu ntau zaus thiab tus nqi.
III. Daim ntawv thov scenarios
Gas-insulated switchgear tau dav siv nyob rau hauv ntau qhov chaw vim nws qhov tshwj xeeb zoo:
1. Muaj automation tswj:Hauv cov chaw tsim khoom loj thiab cov kab ntau lawm, roj-insulated switchgear yog dav siv vim nws cov kev ua tau zoo thiab kev ruaj ntseg kom ntseeg tau tias kev ua haujlwm zoo ntawm cov txheej txheem ntau lawm.
2. Fais fab kis thiab faib qhov system:GIS cov khoom siv dav siv hauv kev sib kis, kev sib txuas thiab kev sib txuas ntawm lub zog hluav taws xob. Nws cov nyhuv rwb thaiv tsev zoo thiab kev ua haujlwm ruaj khov hauv lub xeev ua kom muaj kev nyab xeeb ntawm lub zog hluav taws xob.
3. Cov chaw zov me nyuam thiab cov chav neeg rau zaub mov:Cov chaw zov me nyuam cov ntaub ntawv thiab cov chaw network muaj cov kev xav tau siab heev rau kev ruaj ntseg thiab kev nyab xeeb ntawm cov khoom siv. Qhov kev ua tau zoo heev thiab kev ntseeg siab ntawm cov roj-insulated switchgear ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov chaw no.
4. Cov tsev lag luam thiab cov chaw ua lag luam:Lub tshuab hluav taws xob sab hauv thiab cov chav hloov pauv ntawm cov tsev lag luam loj, nrog rau lub chaw tswj hwm lub cev muaj zog hauv cov chaw tsim khoom lag luam, feem ntau siv cov roj hluav taws xob hluav taws xob hloov hluav taws xob los xyuas kom muaj kev ruaj ntseg thiab kev tiv thaiv kev ruaj ntseg ntawm cov khoom siv.
IV. Muaj qhov tsis txaus
Txawm hais tias gas-insulated switchgear muaj ntau qhov zoo, nws kuj muaj qee qhov tsis zoo:
1. Tus nqi siab:Tus nqi ntawm GIS txee yog qhov siab thiab tsis haum rau cov tshuab hluav taws xob me.
2. Cov kev xav tau siab rau cov neeg ua haujlwm:Kev ua haujlwm ntawm GIS txee yuav tsum muaj cov kws tshaj lij thiab xav tau kev ua haujlwm siab ntawm cov neeg ua haujlwm.
3. Cov nqi kho mob siab:Txawm hais tias kev saib xyuas tag nrho cov haujlwm raug txo qis, kev tshuaj xyuas thiab kev saib xyuas ntawm GIS cov txee tseem xav tau cov nqi siab.
