1. SF6 igesiindawo engaphansi kwe-insulated
I-SF6 gas insulated substation (GIS) iqukethe izinto eziningiSF6 igesii-switchgear evalekile ehlanganiswe endaweni ebiyelwe ngaphandle, engafinyelela ileveli yokuvikela ye-IP54. Ngobuhle bekhono lokufakwa kwegesi ye-SF6 (umthamo wokuphuka kwe-arc uphindwe izikhathi eziyi-100 kunomoya), isiteshi esingaphansi kwegesi esingasebenza ngokuzinza iminyaka engaphezu kwengama-30. Zonke izingxenye ezibukhoma zifakwa ethangini lensimbi engenasici elivalwe ngokugcwele eligcweleSF6 igesi. Lo mklamo ungaqinisekisa ukuthi i-GIS ithembekile kakhulu phakathi nempilo yesevisi futhi idinga ukulungiswa okuncane.
Isiteshi esincane esifakwe igesi kagesi kagesi ophakathi nendawo ngokuvamile sakhiwe nge-switchgear engu-11KV noma engu-33KV. Lezi zinhlobo ezimbili zeziteshi ezincane ezifakwe igesi zingahlangabezana nezidingo zokusetshenziswa kwamaphrojekthi amaningi.
Isiteshi se-GIS insulated switchgear ngokuvamile samukela idizayini yesakhiwo esongayo nesihlangene ngesikhathi sokwakhiwa, ngakho-ke izinzuzo zesiteshi esincane se-GIS zimi kanje:
Uma kuqhathaniswa nesiteshi esincane sosayizi ojwayelekile, sithatha ingxenye eyodwa kweshumi kuphela yesikhala. Ngakho-ke, i-GIS gas insulated substation iyisinqumo esingcono kakhulu samaphrojekthi anendawo encane kanye nomklamo ohlangene.
2. KusukelaSF6 igesiisethangini elivalekile, izingxenye zesiteshi esingaphansi kwegesi ezifakwe igesi zizosebenza esimweni esizinzile, futhi kuzoba nokwehluleka okumbalwa kunesiteshi esincane esifakwe umoya.
3. Ukusebenza okuthembekile nokugcinwa ngaphandle kokunakekelwa.
Ububi besiteshi segesi esifakwe igesi ye-GIS:
1. Izindleko zizoba phezulu kunesiteshi esincane esivamile
2. Uma kwenzeka ukwehluleka, kuthatha isikhathi eside ukuthola imbangela yokwehluleka nokulungisa isiteshi esincane se-GIS.
3. Ikhabhinethi yamamojula ngayinye kufanele ibe ne-SF6 igesiigeji yokucindezela ukuqapha ingcindezi yegesi yangaphakathi. Ukwehliswa kwengcindezi yegesi kwanoma iyiphi imojula kuzoholela ekuhlulekeni kwesiteshi sonke esifakwe igesi.
2. Ukulimala kokuvuza kwe-sulphur hexafluoride
I-Sulfur hexafluoride ehlanzekile (SF6)iyigesi engenabuthi futhi engenaphunga. Amandla adonsela phansi athile egesi ye-sulphur hexafluoride aphakeme kunomoya. Ngemuva kokuvuza, ishona phansi futhi akulula ukuyishintsha. Ngemva kokuhogela umzimba womuntu, izonqwabelana emaphashini isikhathi eside. Ukungakwazi ukukhipha, okuholela ekunciphiseni umthamo wamaphaphu, i-dyspnea enzima, ukuphefumula kanye neminye imiphumela emibi. Uma kubhekwa umonakalo odalwe ukuvuza kwegesi ye-Sf6 sulfur hexafluoride emzimbeni womuntu, ochwepheshe banikeza lokhu okulandelayo:
1. I-Sulfur hexafluoride iyi-ejenti encisha umoya. Emazingeni aphezulu, kungabangela ubunzima bokuphefumula, ukukhwehlela, isikhumba esiluhlaza okwesibhakabhaka kanye nolwelwesi lwamafinyila, kanye nama-spasms omzimba. Ngemva kokuhogela ingxube ye-80% sulfur hexafluoride + 20% oxygen imizuzu embalwa, umzimba womuntu uzobhekana nokuba ndikindiki kwamalungu ngisho nokufa ngokuphelelwa umoya.
2. Imikhiqizo yokubola yeigesi yesulfure hexafluoridengaphansi kwesenzo se-arc kagesi, njenge-sulphur tetrafluoride, i-sulphur fluoride, i-sulphur difluoride, i-thionyl fluoride, i-sulfuryl difluoride, i-thionyl tetrafluoride ne-hydrofluoric acid, njll. , Zombili zidla kakhulu futhi zinobuthi.
1. I-sulphur tetrafluoride: Kuyigesi engenambala ekamelweni lokushisa elinephunga elimnandi. Ingakhipha intuthu enomswakama emoyeni, okuyingozi emaphashini futhi kuthinte isimiso sokuphefumula. Ubuthi bayo bulingana nobephosgene.
2. I-Sulfur fluoride: Iyigesi engenambala ekamelweni lokushisa, inobuthi, inephunga elimnandi, futhi inomphumela olimazayo ofana ne-phosgene ohlelweni lokuphefumula.
3. I-Sulfur difluoride: Izakhiwo zamakhemikhali azinzile ngokwedlulele, futhi ukusebenza kusebenza kakhulu ngemva kokushisisa, futhi i-hydrolyzed kalula ibe yisulfure, i-sulphur dioxide ne-hydrofluoric acid.
4. I-Thionyl fluoride: Iwumoya ongenambala, iphunga lamaqanda abolile, inamakhemikhali azinzile, futhi iyigesi enobuthi obunamandla engabangela ukuqubuka okukhulu kwamaphaphu futhi icindezele izilwane zife.
5. I-Sulfuryl difluoride: Igesi engenambala nengenaphunga enamakhemikhali azinze ngokwedlulele. Kuyigesi enobuthi engabangela ama-spasms. Ingozi yayo ukuthi ayinalo iphunga elibuhlungu futhi ngeke ibangele ukucasuka ku-mucosa yamakhala, ngakho-ke izovame ukufa ngokushesha ngemva kokungenwa ubuthi.
6. I-Tetrafluorothionyl: Igesi engenambala nephunga elimnandi, eliyingozi emaphashini.
7. I-Hydrofluoric acid: Yinto edla kakhulu ku-asidi. Inomphumela onamandla ovuselelayo esikhumbeni kanye nolwelwesi lwamafinyila, futhi ingabangela i- pulmonary edema kanye ne-pneumonia.
Sf6 igesi yesulfure hexafluorideukuvuza kokwelashwa kwezimo eziphuthumayo: khipha ngokushesha abasebenzi endaweni engcolile uye emoyeni ongaphezulu, futhi ubahlukanise, ukhawule ukufinyelela. Kutuswa ukuthi abasebenzi bezimo eziphuthumayo bagqoke amathuluzi okuphefumula okuphefumula kahle ezimele kanye nezingubo zokusebenza ezijwayelekile. Sika umthombo wokuvuza ngangokunokwenzeka. Ukungena komoya okunengqondo ukusheshisa ukusabalalisa. Uma kungenzeka, sebenzisa ngokushesha. Iziqukathi ezivuzayo kufanele ziphathwe kahle futhi zisetshenziswe ngemva kokulungiswa nokuhlolwa.
Iigesi yesulfure hexafluorideukuthola umsebenzi weSF6 igesiindawo engaphansi evalekile itholwa inzwa ye-SF6. Uma ukuvuza kwenzeka noma isilinganiso sidlula izinga, okokuqala ngqa ithola futhi ithumele i-alamu yasendaweni noma i-SMS ekude noma i-alamu yocingo ukuze ikhumbuze abasebenzi ukuthi bayishiye indawo eyingozi futhi bavimbele ngempumelelo ukulimala okukhulu okubangelwa ukuvuza kwegesi.
