1. SF6 gasimalo okhala ndi insulated
SF6 gas insulated substation (GIS) imakhala ndi angapoSF6 gasima switchgear otsekeredwa ophatikizidwa mumpanda wakunja, womwe ungafikire mulingo wachitetezo cha IP54.Ndi mwayi wa SF6 kutchinjiriza gasi mphamvu (arc breaking mphamvu ndi 100 kuposa mpweya), gasi insulated substation akhoza kugwira ntchito mokhazikika kwa zaka 30.Ziwalo zonse zamoyo zimayikidwa mu thanki yachitsulo chosapanga dzimbiri yomata yodzazaSF6 gasi.Kukonzekera kumeneku kungatsimikizire kuti GIS ndi yodalirika kwambiri panthawi yautumiki ndipo imafuna kusamalidwa kochepa.
Sitima yapakatikati yamagetsi yamagetsi yamagetsi nthawi zambiri imakhala ndi 11KV kapena 33KV gas insulated switchgear.Mitundu iwiriyi ya malo otetezedwa ndi gasi imatha kukwaniritsa zofunikira pama projekiti ambiri.
GIS gas insulated switchgear station nthawi zambiri imagwiritsa ntchito kapangidwe kazachuma komanso kocheperako pakumanga, chifukwa chake zabwino zamagawo a GIS ndi motere:
Poyerekeza ndi kagawo kakang'ono ka switchgear, imangotenga gawo limodzi mwa magawo khumi a danga.Chifukwa chake, malo otetezedwa ndi gasi a GIS ndiye chisankho chabwino kwambiri pama projekiti okhala ndi malo ang'onoang'ono komanso kapangidwe kakang'ono.
2. PopezaSF6 gasiili mu thanki yotsekedwa, zigawo za gasi zotsekedwa zidzagwira ntchito mokhazikika, ndipo padzakhala zolephera zocheperapo kusiyana ndi malo otetezedwa ndi mpweya.
3. Ntchito yodalirika komanso yosamalidwa bwino.
Kuipa kwa GIS gas insulated substation:
1. Mtengo udzakhala wokwera kuposa siteshoni wamba
2. Kukanika kuchitika, zimatenga nthawi yayitali kuti mupeze chomwe chalephereka ndikukonza kagawo kakang'ono ka GIS.
3. Kabati iliyonse ya module iyenera kukhala ndiSF6 gasiPressure gauge kuyang'anira kuthamanga kwa gasi wamkati.Kuchepetsa mphamvu ya gasi ya module iliyonse kumabweretsa kulephera kwa gawo lonse la gasi.
2. Kuwonongeka kwa sulfure hexafluoride kutayikira
Sulfur hexafluoride yoyera (SF6)ndi mpweya wopanda poizoni komanso wopanda fungo.Mphamvu yokoka ya gasi wa sulfure hexafluoride ndi wapamwamba kuposa mpweya.Pambuyo pa kutayikira, imamira pamlingo wocheperapo ndipo sikophweka kugwedezeka.Pambuyo pokokedwa ndi thupi la munthu, imawunjikana m'mapapo kwa nthawi yayitali.Kulephera kutulutsa, zomwe zimapangitsa kuchepa kwa mapapu, kukomoka kwambiri, kupuma movutikira ndi zotsatira zina zoyipa.Poganizira zovulaza zomwe zimayambitsidwa ndi kutuluka kwa mpweya wa Sf6 sulfur hexafluoride m'thupi la munthu, akatswiri amapereka zotsatirazi:
1. Sulfur hexafluoride ndi chinthu cholepheretsa kupuma.Kuchuluka kwambiri, kungayambitse kupuma movutikira, kupuma movutikira, khungu la buluu ndi mucous nembanemba, komanso kupindika kwa thupi.Pambuyo pokoka chisakanizo cha 80% sulfure hexafluoride + 20% mpweya kwa mphindi zingapo, thupi la munthu lidzamva dzanzi la miyendo ngakhale kufa chifukwa cha kupuma.
2. Zowonongeka zampweya wa sulfure hexafluoridepansi pa mphamvu ya arc yamagetsi, monga sulfure tetrafluoride, sulfure fluoride, sulfure difluoride, thionyl fluoride, sulfuryl difluoride, thionyl tetrafluoride ndi hydrofluoric acid, ndi zina zotero.
1. Sulfur tetrafluoride: Ndi gasi wopanda mtundu womwe umatenthedwa ndi fungo lonunkhira bwino.Ikhoza kupanga utsi ndi chinyezi mumlengalenga, zomwe zimakhala zovulaza m'mapapo komanso zimakhudza kupuma.Kawopsedwe wake ndi wofanana ndi phosgene.
2. Sulfur fluoride: Ndi gasi wopanda mtundu wa kutentha kwa chipinda, poizoni, ali ndi fungo lopweteka, ndipo ali ndi zotsatira zowononga zofanana ndi phosgene ku dongosolo la kupuma.
3. Sulfur difluoride: Mankhwala ake ndi osakhazikika kwambiri, ndipo ntchito yake imakhala yogwira ntchito ikatenthedwa, ndipo imasinthidwa mosavuta kukhala sulfure, sulfure dioxide ndi hydrofluoric acid.
4. Thionyl fluoride: Ndi mpweya wopanda mtundu, fungo la mazira ovunda, uli ndi mankhwala okhazikika, ndipo ndi mpweya wapoizoni kwambiri womwe ungayambitse edema ya m'mapapo ndi kupha nyama.
5. Sulfuryl difluoride: Ndi mpweya wopanda mtundu komanso wopanda fungo wokhala ndi mankhwala okhazikika kwambiri.Ndi mpweya wapoizoni womwe ungayambitse spasms.Choopsa chake ndi chakuti alibe fungo lopweteka ndipo sichidzayambitsa kupsa mtima kwa mucosa wamphuno, choncho nthawi zambiri imafa mwamsanga pambuyo poyidwa ndi poizoni.
6. Tetrafluorothionyl: Ndi mpweya wopanda mtundu wokhala ndi fungo lopweteka, lomwe limawononga mapapu.
7. Hydrofluoric acid: Ndi chinthu chowononga kwambiri mu asidi.Lili ndi mphamvu zolimbikitsa pakhungu ndi mucous nembanemba, ndipo zingayambitse pulmonary edema ndi chibayo.
Sf6 sulfure hexafluoride mpweyaThandizo ladzidzidzi latayikira: Chotsani mwachangu ogwira ntchito pamalo omwe adatayidwa kupita nawo kumphepo yam'mwamba, ndikuwapatula, kuwaletsa kulowa.Ndibwino kuti ogwira ntchito zamwadzidzidzi azivala zida zopumira bwino komanso zovala zogwirira ntchito.Dulani gwero la kutayikira momwe mungathere.Wololera mpweya wabwino kuti imathandizira kufalikira.Ngati n'kotheka, gwiritsani ntchito nthawi yomweyo.Zotengera zomwe zikutuluka zimayenera kusamaliridwa bwino ndikugwiritsidwa ntchito pambuyo pokonza ndikuwunika.
Thempweya wa sulfure hexafluoridekuzindikira ntchito yaSF6 gasimalo otetezedwa amazindikiridwa ndi sensa ya SF6.Pamene kutayikira kumachitika kapena chiŵerengero chikuposa muyezo, nthawi yoyamba imazindikira ndikutumiza alamu pamalopo kapena ma SMS akutali kapena alamu ya foni kuti akumbutse ogwira ntchito kuti achoke m'dera lowopsa ndikupewa kuvulaza kwakukulu komwe kumachitika chifukwa cha kutuluka kwa gasi.
