Gas insulatedswitchgear(GIS) tau hloov pauv lub zog faib kev lag luam nrog nws cov qauv tsim thiab kev ua tau zoo dua. Cov thev naus laus zis tshiab no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm thiab tswj lub zog hluav taws xob hauv ntau yam kev siv, los ntawm cov chaw siv hluav taws xob mus rau cov chaw tsim khoom. Hauv phau ntawv qhia no, peb yuav tshawb xyuas cov haujlwm sab hauv ntawm cov roj hluav taws xob hluav taws xob hloov hluav taws xob, nws cov khoom tseem ceeb, txheej txheem sib dhos, thiab ntau qhov zoo uas nws muaj tshaj li cov kev daws teeb meem ib txwm muaj.
Dab tsiYogtusCov ntsiab lus tseem ceebntawmGas Insulated Switchgear?
Gas insulated switchgear suav nrog ntau yam tseem ceeb uas ua haujlwm sib haum xeeb kom muaj kev nyab xeeb thiab siv hluav taws xob zoo. Cia peb delve rau hauv cov ntsiab lus tseem ceeb uas ua rau qhov kev hloov pauv siab tshaj plaws no:
Circuit Breakers
Lub plawv ntawm txhua qhov system switchgear, Circuit Court breakers hauv GIS yog tsim los cuam tshuam cov hluav taws xob tam sim no thaum muaj teeb meem txhaum cai lossis rau kev saib xyuas niaj hnub. Cov breakers no siv sulfur hexafluoride (SF6) gas ua ib qho nruab nrab ntawm insulating thiab arc-quenching, tso cai rau kev cuam tshuam sai thiab zoo tam sim no.
Disconnectors thiab Earthing Switcher
Disconnectors pab cais cov seem sib txawv ntawm lub switchgear, ua kom muaj kev ruaj ntseg ua haujlwm. Earthing keyboards, ntawm qhov tod tes, muab kev sib txuas ncaj qha rau hauv av, ua kom cov neeg ua haujlwm muaj kev nyab xeeb thaum ua haujlwm tu.
Tam sim no thiab Voltage Transformers
Cov khoom tseem ceeb no yog lub luag haujlwm rau kev ntsuas hluav taws xob tsis nyob hauv lub switchgear. Tam sim no transformers saib xyuas qhov ntws ntawm hluav taws xob, thaum lub zog hluav taws xob hloov hluav taws xob txo qis qhov hluav taws xob siab mus rau qib tsim nyog rau kev ntsuas thiab kev tiv thaiv cov cuab yeej.
Busbars
Busbars yog lub ntsiab conductors uas faib hluav taws xob hluav taws xob thoob plaws lub switchgear. Nyob rau hauv GIS, cov busbars tau kaw nyob rau hauv cov khoom ntim roj, muab cov rwb thaiv tsev zoo heev thiab txo qhov kev pheej hmoo ntawm hluav taws xob tsis zoo.
Gas-Filled Compartments
Tag nrhoswitchgearKev sib dhos yog nyob hauv cov khoom siv roj nruj uas muaj cov roj SF6. Qhov no inert gas muab superior rwb thaiv tsev zog, tso cai rau compact tsim thiab txhim khu kev qha.
Yuav ua li casYog Gas Insulated Switchgear AssembledthiabNruab?
Kev sib dhos thiab kev teeb tsa ntawm cov roj hluav taws xob insulated switchgear xav tau qhov tseeb thiab kev txawj ntse kom ntseeg tau tias kev ua haujlwm zoo thiab kev nyab xeeb. Cia peb tshuaj xyuas cov kauj ruam tseem ceeb hauv txoj kev no:
Factory Assembly
GIS Cheebtsam yog feem ntau pre-assembled nyob rau hauv lub Hoobkas tswj ib puag ncig kom tswj tau zoo thiab txo lub sij hawm installation ntawm qhov chaw. Cov txheej txheem no suav nrog:
- Kev Npaj Chav Ua Haujlwm: Ib tus kheej cov khoom ntim roj tau ua tib zoo tsim thiab kaw.
- Component Integration: Circuit Court breakers, disconnectors, thiab lwm yam khoom raug ntsia rau hauv lawv cov compartments.
- Cov Hluav Taws Xob thiab Cov Hluav Taws Xob: Kev sib txuas hluav taws xob thiab cov tshuab tswj tau ua tib zoo sib xyaw ua ke.
On-site Installation
Thaum cov chav nyob ua ntej tuaj txog ntawm qhov chaw teeb tsa, cov kauj ruam hauv qab no tau ua:
- Kev Npaj Foundation: Lub hauv paus ruaj khov yog npaj los txhawb qhov hnyav thiab qhov ntev ntawm GIS.
- Kev Ua Haujlwm thiab Kev Ua Haujlwm: Cov GIS units tau ua tib zoo tso thiab ua raws li qhov chaw teeb tsa.
- Inter-Compartment Connections: Gas-tight kev sib txuas yog tsim los ntawm ib tug neeg compartments los tsim ib tug unified system.
Gas filling thiab kuaj
Cov theem kawg ntawm kev teeb tsa suav nrog:
- Kev tsim lub tshuab nqus tsev: Huab cua tau khiav tawm ntawm cov chav tsev los tsim lub tshuab nqus tsev.
- SF6 Gas Filling: Cov khoom ntim tau ntim nrog SF6 roj rau cov qib siab.
- Kev sim nruj: Cov kev sim ua tiav tau ua los xyuas kom muaj kev ua haujlwm zoo, roj nruj, thiab kev ua haujlwm tag nrho.
Dab tsiYogtusQhov zoontawmSiv Gas Insulated Switchgear?
Gas insulatedswitchgearmuaj ntau yam txiaj ntsig tshaj li cov pa cua-insulated switchgear, ua rau nws muaj kev xaiv nrov dua rau cov tshuab hluav taws xob niaj hnub no:
Compact Design
GIS xav tau qhov chaw tsawg dua piv rau cov khoom siv hluav taws xob, ua rau nws zoo tagnrho rau cov chaw hauv nroog lossis thaj chaw uas muaj vaj tse tsawg. Qhov kev tsim qauv compact no tuaj yeem txo cov hneev taw mus txog rau 70-80% piv rau cov kev hloov pauv huab cua.
Txhim khu kev ruaj ntseg
Lub kaw lus tsim ntawm GIS txo qhov kev pheej hmoo ntawm hluav taws xob xwm txheej thiab arc flashes. Lub SF6 roj rwb thaiv tsev muab cov khoom zoo heev arc-quenching, txhim khu kev ruaj ntseg tag nrho.
Txhim kho kev ntseeg tau
GIS systems tsis tshua muaj kev cuam tshuam rau ib puag ncig xws li plua plav, av noo, thiab cov pa phem. Qhov no ua rau txo cov kev xav tau kev saib xyuas thiab txhim kho kev ntseeg tau ntev.
Cov nqi kho mob qis dua
Qhov kaw qhov xwm txheej ntawm GIS tiv thaiv cov khoom sab hauv los ntawm ib puag ncig kev puas tsuaj, ua rau txo cov kev xav tau ntawm kev saib xyuas thiab txo cov nqi khiav lag luam hauv lub neej.
Ntev Lifespan
Nrog kev tu kom zoo, roj insulatedswitchgeartuaj yeem muaj kev ua neej nyob ntev ntawm 40-50 xyoo, ntev dua li cov tshuab hloov iav. Qhov kev ua neej ntev no txhais tau tias txhim kho tus nqi zoo thiab txo qhov xav tau kev hloov pauv.
Kev tiv thaiv ib puag ncig
Thaum SF6 yog lub tsev cog khoom siv roj, niaj hnub GIS tsim kev sib txuas cov thev naus laus zis thev naus laus zis thiab kev soj ntsuam cov roj kom txo qis. Tsis tas li ntawd, cov qauv tsim ntawm GIS txo qhov kev cuam tshuam ib puag ncig tag nrho los ntawm kev xav tau cov av tsawg dua thiab cov khoom siv tsim kho.
Flexibility hauv Design
GIS tuaj yeem teeb tsa hauv ntau qhov kev npaj kom haum rau qhov project tshwj xeeb. Nws cov qauv tsim qauv tso cai rau kev nthuav dav yooj yim thiab kho dua tshiab raws li kev faib hluav taws xob xav tau hloov zuj zus mus rau lub sijhawm.
Txo suab nrov
Qhov xwm txheej ntawm GIS txo qis kev ua haujlwm suab nrov piv rau cua-insulated switchgear, ua rau nws tsim nyog rau kev teeb tsa hauv thaj chaw suab nrov.
Kev Ua Phem Rau Ib puag ncig hnyav
Gas insulated switchgear ua tau zoo tshwj xeeb hauv cov cheeb tsam nyuaj, suav nrog thaj chaw uas muaj cov av noo siab, huab cua ntsev-laden, lossis kub heev. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau thaj chaw ntug dej hiav txwv, chaw tsim khoom, thiab thaj chaw uas muaj huab cua hnyav.
Xaus
Gas insulatedswitchgear sawv cev rau kev nce qib tseem ceeb hauv kev siv hluav taws xob faib hluav taws xob. Nws txoj kev tsim tshiab, sib txuas ua ke SF6 roj rwb thaiv tsev nrog cov compact, kaw qhov sib txuas, muab ntau cov txiaj ntsig suav nrog kev txuag chaw, txhim kho kev nyab xeeb, txhim kho kev ntseeg siab, thiab txo kev saib xyuas. Raws li qhov kev thov kom muaj txiaj ntsig zoo thiab txhim khu kev qha hluav taws xob txuas ntxiv zuj zus, GIS tau npaj los ua lub luag haujlwm tseem ceeb hauv kev tsim lub neej yav tom ntej ntawm cov khoom siv hluav taws xob.
