1. SF6 rojinsulated hloov
SF6 roj insulated hloov (gis) muaj ntau yamSF6 rojInsulated Switchgear ua ke hauv ib sab nraum zoov ntim, uas tuaj yeem mus cuag IP54 kev tiv thaiv qib. Nrog qhov kom zoo dua ntawm SF6 roj Rwb thaiv tsev muaj peev xwm (lub peev xwm arc rwb yog 100 npaug ntawm huab cua), cov pa roj yeeb tshuaj tuaj yeem ua haujlwm ruaj khov rau ntau dua 30 xyoo. Txhua qhov chaw nyob tau muab tso rau hauv ib qho kev sib khi ntawm cov hlau hluav taws xob tag nrho tank puv nrogSF6 rojCov. Cov qauv no tuaj yeem ua kom ntseeg tau tias GIS yog kev ntseeg tau ntau thaum lub sijhawm pabcuam thiab xav tau kev txij nkawm tsawg dua.
Lub nruab nrab voltage roj insulated hloov yog feem ntau muaj ntawm 11kv lossis 33kv roj insulated Switchgear. Ob hom roj av insulated no tuaj yeem ua tau raws li daim ntawv thov yuav tsum muaj ntawm cov phiaj xwm feem ntau.
GIS roj insulated switchgear chaw nres tsheb feem ntau lees txais kev tsim kho thiab kev sib xyaw ua ke ntawm gIS hloov yog raws li hauv qab no:
Piv nrog cov kev hloov pauv hloov pauv ib txwm hloov, nws tsuas yog xaiv ib feem kaum ntawm qhov chaw. Yog li ntawd, GIS roj insulated hloov yog qhov kev xaiv zoo tshaj plaws rau cov phiaj xwm nrog cov chaw me me thiab tsim qauv kev teeb tsa.
2. Txij li thaum lubSF6 rojPuas yog hauv lub tank ntim khoom, cov pa roj insulated hloov Cheebtsam yuav ua haujlwm nyob rau hauv ib lub xeev ruaj khov, thiab yuav muaj tsawg tsawg dua cov pa hluav taws xob.
3. Txhim khu kev qha ua tau zoo thiab kev saib xyuas-dawb.
Qhov tsis zoo ntawm GIS roj insulated hloov:
1. Tus nqi yuav siab dua li hloov chaw
2. Thaum tsis ua tiav tshwm sim, nws siv sijhawm ntev dua los nrhiav qhov ua rau tsis ua tiav thiab kho lub gIS hloov.
3. Txhua tus module txee yuav tsum tau nruab nrog ibSF6 rojSiab koob tsomeej txhawm rau saib xyuas cov roj sab hauv. Cov roj av txo qis ntawm ib qho module yuav ua rau tag nrho cov roj insulated hloov.
2. Qhov kev tsim txom ntawm cov sulphur hexafluoride to
Cov neeg ntshiab sulfur hexafluoride (SF6)yog cov tsis muaj tshuaj lom thiab odorless roj. Cov kev sib nqus tshwj xeeb ntawm cov sulphur hexafluoride roj yog siab dua li ntawm huab cua. Tom qab toaste, nws tog kom qis dua qib thiab tsis yooj yim rau kev loj hlob. Tom qab nqus tau los ntawm tib neeg lub cev, nws yuav nthuav tawm lub ntsws ntev. Kev tsis muaj peev xwm ua tau zoo los, ua rau muaj kev puas tsuajung muaj peev xwm, mob dyspnea hnyav, kev ua tsis taus pa thiab lwm yam kev sib raug zoo. Hauv kev pom ntawm cov kev raug mob tshwm sim los ntawm kev xau ntawm SF6 Sulfur Hexaflur Hexafluoride Gas rau tib neeg lub cev, cov kws tshaj lij muab cov hauv qab no:
1. Sulphur hexafluoride yog ib tus neeg sawv cev ua kom tiav. Hauv cov kev muaj zog ntau, nws tuaj yeem ua rau ua pa nyuaj, hawb pob, tawv nqaij thiab cov tawv nqaij xiav thiab lub cev. Tom qab nqus tau ntawm 80% sulfur hexygen rau ob peb feeb, tib neeg lub cev yuav ua kom loog ntawm cov nqua thiab tuag taus los ntawm asphyxiation.
2. Tus decomposition cov khoom lag luam ntawmSulphur Hexafluoride GasNyob rau hauv qhov kev txiav txim ntawm hluav taws xob arc, xws li sulfur tetruaruoride, sulfur fluoride, ilionyllluoric acid, thiab lwm yam.
1. Sulphur Tetraflub Sab: Nws yog cov pa roj tsis muaj kob nyob ntawm chav tsev kub nrog lub pungent tsw. Nws tuaj yeem tsim cov pa luam yeeb nrog cov dej noo hauv huab cua, uas yog qhov muaj kev phom sij rau lub ntsws thiab cuam tshuam rau lub tshuab ua pa. Nws cov kuab lom yog sib npaug rau qhov ntawd ntawm phosgene.
2. Cov roj fluoride: Nws yog cov pa roj tsis muaj xim nyob rau hauv chav tsev kub, muaj kev phom sij pungent zoo ib yam li kev ua pa rau lub tshuab ua pa.
3. Sulfur difluoride: Cov tshuaj lom neeg muaj zog tsis ruaj khov, thiab kev ua haujlwm tau yooj yim dua tom qab cua sov, thiab nws yooj yim hydrolyzed rau hauv cov leej faj, sulfur dioxide thiab hydrofluoric acid.
4. Thionyl Tshuaj Fluoride: Nws yog cov pa roj tsis muaj ntxhiab, muaj cov tshuaj lom neeg uas muaj peev xwm ruaj khov uas tuaj yeem ua rau muaj cov tsiaj muaj sia nyob hnyav heev rau kev tuag.
5. SulfulyL difluide: Nws yog cov pa roj tsis muaj xim thiab ntxhiab tsw muaj tshuaj lom neeg siv tshuaj. Nws yog cov roj lom uas tuaj yeem ua rau ntuav. Nws qhov kev phom sij yog tias nws tsis muaj ntxhiab tsw thiab yuav tsis ua rau kev npau taws rau lub qhov ntswg mucosa, yog li nws yuav tuag sai sai tom qab raug lom.
6. Tetrafluorothionyl: nws yog cov roj uas tsis muaj kob nrog lub plab pungent, uas yog kev tsim kev puas tsuaj rau lub ntsws.
7. Hydlofluoric acid: nws yog cov tshuaj corrosive tshaj plaws hauv acid. Nws muaj qhov muaj zog txhawb cov nyhuv rau ntawm daim tawv nqaij thiab cov tawv nqaij tsis haum, thiab tuaj yeem ua rau cov mob ntsws ntsws thiab mob ntsws.
SF6 SULFUR Hexafluoride GasKev cheb tau kub ntxhov: Kev khiav tawm ceev ceev tawm ntawm thaj chaw xau rau cov cua daj, thiab cais lawv cov, nruj me ntsis kev nkag mus. Nws raug nquahu tias cov neeg ua lag luam ceev hnav kom muaj kev ua pa zoo thiab cov khaub ncaws ua haujlwm dav dav. Txiav tawm ntawm qhov chaw xau dej ntau li ntau tau. Tsim nyog cua nkag mus nrawm diffusion. Yog tias ua tau, siv nws tam sim ntawd. Leaking cov ntim yuav tsum tau ua kom zoo thiab siv tom qab kho thiab tshuaj xyuas.
TusSulphur Hexafluoride GasKev Nrhiav Ua Haujlwm Ntawm CovSF6 rojCov tshuaj insulated yog kuaj los ntawm SF6 sensor. Thaum muaj dej xau lossis qhov piv tau ntau dua tus txheej txheem, thawj zaug uas nws pom thiab xa tawm cov neeg ua haujlwm tawm ntawm thaj chaw txaus ntshai thiab kev mob siab rau los ntawm kev mob siab.
