1. Igesi le-SF6isiteshi esincane esivalekile
Isiteshi esincane esifakwe igesi i-SF6 (GIS) sakhiwe ngezindlela eziningiIgesi le-SF6i-switchgear evalekile ehlanganiswe endaweni evalekile yangaphandle, engafinyelela izinga lokuvikelwa kwe-IP54. Ngenzuzo yamandla okuvikela igesi e-SF6 (umthamo wokuphuka kwe-arc uphindwe kayi-100 kunomoya), isiteshi esincane esivalekile segesi singasebenza kahle iminyaka engaphezu kwengu-30. Zonke izingxenye eziphilayo zifakwa ethangini lensimbi engagqwali elivalekile ngokuphelele eligcweleIgesi le-SF6Lo mklamo ungaqinisekisa ukuthi i-GIS ithembeke kakhulu ngesikhathi sempilo yesevisi futhi idinga ukulungiswa okuncane.
Isiteshi esincane esifakwe igesi esinomthamo ophakathi ngokuvamile sakhiwe yi-switchgear efakwe igesi engu-11KV noma engu-33KV. Lezi zinhlobo ezimbili zeziteshi ezincane ezifakwe igesi zingahlangabezana nezidingo zesicelo samaphrojekthi amaningi.
Isiteshi se-switchgear esifakwe igesi ye-GIS sivame ukusebenzisa ukwakheka kwesakhiwo okongayo nokuncane ngesikhathi sokwakhiwa, ngakho-ke izinzuzo zesiteshi esincane se-GIS yilezi ezilandelayo:
Uma kuqhathaniswa nesiteshi esincane se-switchgear esinosayizi ojwayelekile, sithatha ingxenye eyodwa kweziyishumi kuphela yesikhala. Ngakho-ke, isiteshi esincane esifakwe igesi ye-GIS siyindlela engcono kakhulu yamaphrojekthi anesikhala esincane kanye nomklamo omncane.
2. Kusukela ku-Igesi le-SF6uma isethangini elivaliwe, izingxenye zesiteshi esingaphansi esivalwe ngegesi zizosebenza esimweni esizinzile, futhi kuzoba nokwehluleka okuncane kakhulu kunesiteshi esingaphansi esivalwe ngomoya.
3. Ukusebenza okuthembekile nokungenakulungiswa.
Okubi ngesiteshi esincane esifakwe igesi se-GIS:
1. Izindleko zizoba phezulu kunesiteshi esivamile sokushintsha
2. Uma kwenzeka ukwehluleka, kuthatha isikhathi eside ukuthola imbangela yokwehluleka nokulungisa isiteshi esincane se-GIS.
3. Ikhabhinethi ngayinye yemodyuli kumele ifakweIgesi le-SF6i-pressure gauge yokuqapha ingcindezi yangaphakathi yegesi. Ukwehliswa kwengcindezi yegesi kwanoma iyiphi imojuli kuzoholela ekungasebenzi kahle kwesiteshi sonke esifakwe igesi.
2. Umonakalo wokuvuza kwe-sulfur hexafluoride
I-hexafluoride yesulfure emsulwa (SF6)iyigesi engenabo ubuthi futhi engenaphunga. Amandla adonsela phansi egesi ye-sulfur hexafluoride aphezulu kunomoya. Ngemva kokuvuza, ishona ezingeni eliphansi futhi akulula ukuyiphefumula. Ngemva kokuhogela umzimba womuntu, izoqongelela emaphashini isikhathi eside. Ukungakwazi ukukhipha, okuholela ekunciphiseni amandla emaphashini, ukuphelelwa umoya okukhulu, ukuminyana kanye neminye imiphumela emibi. Ngenxa yomonakalo obangelwa ukuvuza kwegesi ye-Sf6 sulfur hexafluoride emzimbeni womuntu, ochwepheshe banikeza okulandelayo:
1. I-hexafluoride ye-sulfur iyisithako esiklinyayo. Uma igxilwe kakhulu, ingabangela ubunzima bokuphefumula, ukuphefumula kanzima, isikhumba esiluhlaza okwesibhakabhaka kanye nolwelwesi lwamafinyila, kanye nokuqina komzimba. Ngemva kokuphefumula ingxube ye-hexafluoride ye-sulfur engu-80% + umoya-mpilo ongu-20% imizuzu embalwa, umzimba womuntu uzozwa ukungakhululeki kwamalungu ngisho nokufa ngenxa yokufutha.
2. Imikhiqizo yokubola kwe-igesi ye-hexafluoride yesulfurengaphansi kwesenzo se-arc kagesi, njenge-sulfur tetrafluoride, i-sulfur fluoride, i-sulfur difluoride, i-thionyl fluoride, i-sulfuryl difluoride, i-thionyl tetrafluoride kanye ne-hydrofluoric acid, njll., Zombili zingcolisa kakhulu futhi zinobuthi.
1. I-tetrafluoride yesulfure: Kuyigesi engenambala ekamelweni lokushisa enephunga elibi. Ingakhipha intuthu enomswakama emoyeni, okuyingozi emaphashini futhi kuthinte uhlelo lokuphefumula. Ubuthi bayo bufana nobe-phosgene.
2. I-sulfur fluoride: Iyigesi engenambala ekamelweni lokushisa, inobuthi, inephunga elibi, futhi inomphumela olimazayo ofana ne-phosgene ohlelweni lokuphefumula.
3. I-sulfur difluoride: Izakhiwo zamakhemikhali azizinzile kakhulu, futhi ukusebenza kwazo kusebenza kakhulu ngemva kokushisa, futhi zifakwa kalula ku-hydrolyzed zibe yi-sulfur, i-sulfur dioxide kanye ne-hydrofluoric acid.
4. I-Thionyl fluoride: Iyigesi engenambala, iphunga lamaqanda abolile, inezakhiwo zamakhemikhali ezizinzile, futhi iyigesi enobuthi kakhulu engabangela ukuvuvukala okukhulu kwamaphaphu futhi ibulale izilwane.
5. I-Sulfuryl difluoride: Iyigesi engenambala futhi engenaphunga enezakhiwo zamakhemikhali ezizinzile kakhulu. Iyigesi enobuthi engabangela ukuqaqamba. Ingozi yayo ukuthi ayinaphunga elibi futhi ngeke ibangele ukucasuka ekhaleni, ngakho-ke ivame ukufa ngokushesha ngemva kokufakwa ubuthi.
6. I-Tetrafluorothionyl: Iyigesi engenambala enephunga elibi, eliyingozi emaphashini.
7. I-Hydrofluoric acid: Iyinto ebolisa kakhulu ku-asidi. Inomthelela omkhulu wokuvuselela esikhumbeni kanye nasezingxeni zamathumbu, futhi ingabangela ukuvuvukala kwamaphaphu kanye ne-pneumonia.
Igesi ye-hexafluoride yesulfure ye-Sf6ukwelashwa okuphuthumayo kokuvuza: susa ngokushesha abasebenzi endaweni engcolile evuzayo baye emoyeni ongaphezulu, bese ubahlukanisa, unciphise ukufinyelela. Kunconywa ukuthi abasebenzi be-emergency responsibilities bagqoke imishini yokuphefumula ehambisana nomfutho kanye nezingubo zokusebenza ezijwayelekile. Sika umthombo wokuvuza ngangokunokwenzeka. Umoya ofanele ukuze kusheshiswe ukusabalala. Uma kungenzeka, sebenzisa ngokushesha. Izitsha ezivuzayo kufanele ziphathwe kahle futhi zisetshenziswe ngemva kokulungiswa nokuhlolwa.
Iigesi ye-hexafluoride yesulfureumsebenzi wokuthola weIgesi le-SF6Isiteshi esincane esivalekile sitholwa yinzwa ye-SF6. Uma kwenzeka ukuvuza noma isilinganiso sidlula izinga, okokuqala sithola futhi sithumele i-alamu yasendaweni noma i-SMS ekude noma i-alamu yocingo ukukhumbuza abasebenzi ukuthi bashiye indawo eyingozi futhi bavimbele ngempumelelo ukulimala okukhulu okubangelwa ukuvuza kwegesi.
