1. SF 6 gasinsulated substation
SF6 gas insulated substation (GIS) muaj ntau yamSF 6 gasinsulated switchgear ua ke nyob rau hauv ib qho chaw sab nraum zoov, uas tuaj yeem ncav cuag IP54 tiv thaiv qib. Nrog rau qhov zoo ntawm SF6 roj rwb thaiv tsev muaj peev xwm (lub peev xwm tawg yog 100 npaug ntawm huab cua), cov roj hluav taws xob hluav taws xob tuaj yeem ua haujlwm ruaj khov rau ntau tshaj 30 xyoo. Txhua qhov chaw nyob yog muab tso rau hauv lub tank tag nrho stainless hlau ntim nrogSF 6 gas. Qhov kev tsim no tuaj yeem ua kom ntseeg tau tias GIS muaj kev ntseeg siab dua thaum lub sijhawm ua haujlwm thiab yuav tsum tau saib xyuas tsawg dua.
Qhov nruab nrab voltage roj insulated substation feem ntau yog tsim los ntawm 11KV lossis 33KV gas insulated switchgear. Ob hom roj insulated substations tuaj yeem ua tau raws li daim ntawv thov ntawm feem ntau cov haujlwm.
GIS gas insulated switchgear chaw nres tsheb feem ntau txais kev lag luam thiab kev tsim qauv tsim qauv thaum lub sij hawm tsim kho, yog li qhov zoo ntawm GIS substation yog raws li hauv qab no:
Piv nrog rau qhov loj me me switchgear substation, nws tsuas yog nyob ib feem kaum ntawm qhov chaw. Yog li ntawd, GIS gas insulated substation yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm uas muaj qhov chaw me me thiab tsim qauv compact.
2. Txij li thaumSF 6 gasyog nyob rau hauv lub tank kaw, cov roj insulated substation Cheebtsam yuav ua hauj lwm nyob rau hauv ib tug ruaj khov lub xeev, thiab yuav muaj ntau yam tsis ua hauj lwm ntawm cov huab cua insulated substation.
3. Txhim khu kev ua tau zoo thiab kev tu-dawb.
Disadvantages ntawm GIS gas insulated substation:
1. Tus nqi yuav siab dua li qub substation
2. Thaum muaj qhov tsis ua tiav, nws yuav siv sijhawm ntev dua los nrhiav qhov ua tsis tiav thiab kho GIS substation.
3. Txhua module txee yuav tsum tau nruab nrog ib tugSF 6 gaslub ntsuas ntsuas ntsuas los saib xyuas cov roj hauv lub siab. Kev txo qis roj ntawm ib qho module yuav ua rau tsis ua hauj lwm ntawm tag nrho cov roj insulated substation.
2. Kev puas tsuaj ntawm sulfur hexafluoride to
Pure sulfur hexafluoride (SF6)yog cov roj uas tsis muaj tshuaj lom thiab tsis muaj ntxhiab tsw. Qhov tshwj xeeb lub ntiajteb txawj nqus ntawm sulfur hexafluoride gas yog siab dua li ntawm huab cua. Tom qab xau, nws tog mus rau theem qis thiab tsis yooj yim rau volatilize. Tom qab nqus tau los ntawm tib neeg lub cev, nws yuav khaws cia rau hauv lub ntsws ntev. Tsis muaj peev xwm tso tawm, ua rau lub ntsws muaj peev xwm txo qis, ua tsis taus pa hnyav, ua tsis taus pa thiab lwm yam teebmeem tshwm sim. Nyob rau hauv kev pom ntawm qhov teeb meem tshwm sim los ntawm kev xau ntawm Sf6 sulfur hexafluoride gas rau tib neeg lub cev, cov kws tshaj lij muab cov hauv qab no:
1. Sulfur hexafluoride yog ib tug neeg ua pa. Nyob rau hauv siab concentration, nws tuaj yeem ua rau ua pa nyuaj, hawb pob, daim tawv nqaij xiav thiab mucous daim nyias nyias, thiab lub cev spasms. Tom qab nqus tau ib qho sib xyaw ntawm 80% sulfur hexafluoride + 20% oxygen rau ob peb feeb, tib neeg lub cev yuav hnov mob ntawm nqua thiab txawm tias tuag los ntawm asphyxiation.
2. Cov khoom decomposition ntawmsulfur hexafluoride gasnyob rau hauv qhov kev txiav txim ntawm hluav taws xob arc, xws li sulfur tetrafluoride, sulfur fluoride, sulfur difluoride, thionyl fluoride, sulfuryl difluoride, thionyl tetrafluoride thiab hydrofluoric acid, thiab lwm yam, Lawv yog ob qho tib si muaj zog corrosive thiab tshuaj lom.
1. Sulfur tetrafluoride: Nws yog cov roj tsis muaj xim ntawm chav tsev kub nrog cov ntxhiab tsw ntxhiab. Nws tuaj yeem tsim cov pa luam yeeb nrog cov dej noo hauv huab cua, uas ua rau muaj kev phom sij rau lub ntsws thiab cuam tshuam rau kev ua pa. Nws toxicity yog sib npaug ntawm phosgene.
2. Sulfur fluoride: Nws yog cov roj tsis muaj xim nyob rau hauv chav tsev kub, muaj tshuaj lom, muaj ntxhiab tsw ntxhiab, thiab muaj kev puas tsuaj zoo ib yam li phosgene rau lub ntsws.
3. Sulfur difluoride: Cov khoom siv tshuaj lom neeg tsis ruaj khov, thiab kev ua haujlwm zoo dua tom qab cua sov, thiab nws yooj yim hydrolyzed rau hauv sulfur, sulfur dioxide thiab hydrofluoric acid.
4. Thionyl fluoride: Nws yog cov roj uas tsis muaj xim, tsw ntxhiab ntawm cov qe lwj, muaj cov tshuaj lom neeg ruaj khov, thiab yog cov pa roj uas muaj kuab lom heev uas tuaj yeem ua rau mob ntsws edema thiab ua rau cov tsiaj tuag.
5. Sulfuryl difluoride: Nws yog cov roj tsis muaj xim thiab tsis muaj ntxhiab nrog cov khoom siv tshuaj lom neeg ruaj khov. Nws yog ib qho roj uas muaj kuab lom uas tuaj yeem ua rau spasms. Nws qhov txaus ntshai yog tias nws tsis muaj ntxhiab tsw tsw thiab yuav tsis ua rau khaus ntawm qhov ntswg, yog li nws yuav feem ntau tuag sai sai tom qab raug tshuaj lom.
6. Tetrafluorothionyl: Nws yog cov roj tsis muaj xim nrog cov ntxhiab tsw ntxhiab, uas ua rau lub ntsws tsis zoo.
7. Hydrofluoric acid: Nws yog cov tshuaj corrosive tshaj plaws hauv cov kua qaub. Nws muaj zog stimulating nyhuv ntawm daim tawv nqaij thiab mucous daim nyias nyias, thiab yuav ua rau pulmonary edema thiab pneumonia.
Sf6 sulfur hexafluoride gasKev kho mob xwm txheej ceev: tshem tawm cov neeg ua haujlwm sai sai los ntawm qhov chaw xau cov kab mob mus rau cov cua sab saud, thiab cais lawv, nruj me ntsis txwv kev nkag mus. Nws raug pom zoo tias cov neeg ua haujlwm thaum muaj xwm txheej ceev yuav tsum hnav lub tshuab ua pa zoo rau tus kheej thiab cov khaub ncaws ua haujlwm. Txiav tawm qhov chaw ntawm cov dej ntws tawm kom ntau li ntau tau. Tsim nyog qhov cua kom ceev diffusion. Yog ua tau, siv tam sim ntawd. Cov thawv ntim yuav tsum tau ua kom zoo thiab siv tom qab kho thiab tshuaj xyuas.
Covsulfur hexafluoride gasdetection muaj nuj nqiSF 6 gasinsulated substation yog kuaj los ntawm SF6 sensor. Thaum muaj qhov xau tshwm sim lossis qhov sib piv ntau dua tus qauv, thawj zaug nws pom thiab xa tawm lub tswb ntawm qhov chaw lossis cov chaw taws teeb SMS lossis xov tooj ceeb toom kom cov neeg ua haujlwm tawm hauv qhov chaw txaus ntshai thiab tiv thaiv kev puas tsuaj loj los ntawm cov pa roj.
