Iyini i-perfluoroisobutyronitrile | heptafluoroisobutyronitrile | C4F7N? Yiziphi ukusetshenziswa kwayo?

I-Perfluoroisobutyronitrile C4F7N, njengegesi evikela imvelo enobungani kanye ne-arc-ecisha igesi, iyavela kancane kancane emkhakheni wezisetshenziswa zamandla futhi iba yisixazululo esithandwayo sokuthatha indawo yegesi ye-SF6 yendabuko. Ngeke isetshenziswe iyodwa kuphela, kodwa futhi ixubene ngokuguquguquka negesi eyodwa noma ngaphezulu njenge-CO2, i-N2, i-O2 nomoya, futhi ijovelwe ezindlini ezivaliwe ze-medium-voltage noma imishini ye-voltage ephezulu. Isetshenziswa kakhulu ezingxenyeni zikagesi zongqimba lwe-dielectric, okubonisa ukuguquguquka kwayo okuhle kakhulu kanye namathemba okusebenza abanzi.
Ezimweni zokusetshenziswa kwemishini yamandla aphakathi nendawo naphezulu, igesi ye-Perfluoroisobutyronitrile ibonise uchungechunge lwezici eziphawulekayo: Okokuqala, ubungane bayo bemvelo buvelele ngokukhethekile. Uma kuqhathaniswa ne-SF6, inciphisa kakhulu amandla okulimala kongqimba lwe-ozone futhi isabela ngenkuthalo obizweni lokuvikelwa kwemvelo emhlabeni wonke. Okwesibili, igesi inezakhiwo ezinhle kakhulu zokufakelwa, okuqinisekisa ngokuphumelelayo ukusebenza okuzinzile kwemishini yamandla ngaphansi kwezimo zokusebenza eziyinkimbinkimbi. Ngesikhathi esifanayo, ikhono layo elihle kakhulu lokucisha i-arc linganqamula ngokushesha i-arc ezimweni eziphuthumayo njengamasekhethi amafushane, ukuvikela izinto zokusebenza ekulimaleni, futhi kuthuthukise ukuphepha okuphelele kwesistimu yamandla.
Ngaphezu kwalokho, igesi ye-Perfluoroisobutyronitrile nayo ikhombisa ukuhambisana okuhle nezinto zangaphakathi zokushintshwa, okusho ukuthi ngesikhathi sokuklanywa nokugcinwa kwemishini, asikho isidingo sokukhathazeka ngokuwohloka kokusebenza noma izingozi zokuphepha ezibangelwa ukusabela phakathi kwegesi kanye negesi. impahla. Ubuthi bayo obuphansi bubuye buhlangabezane nezindinganiso eziphakeme zempilo nokuphepha embonini yesimanje, futhi bunganciphisa ngempumelelo ukulimala kwabasebenzi kanye nemvelo ngisho nalapho kuvuza. Okutuseka nakakhulu ukuthi igesi ayinayo i-flash point, okusho ukuthi isengakwazi ukugcina ukusebenza okuzinzile ezindaweni eziphansi kakhulu zokushisa futhi ihlangabezane nezidingo zokufaka isicelo ngaphansi kwezimo ezikhethekile zemvelo.
Kafushane, igesi ye-Perfluoroisobutyronitrile kancane kancane isiba yisinqumo esihle sokuthatha indawo yegesi ye-SF6 emkhakheni wemishini yamandla ngezinzuzo zayo eziningi njengokuvikelwa kwemvelo, ukusebenza kahle okuphezulu nokuphepha. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokukhuthazwa okujulile kwezinhlelo zokusebenza, sinesizathu sokukholelwa ukuthi le nto emisha izodlala indima ebaluleke kakhulu ekuthuthukisweni kwemboni yamandla yesikhathi esizayo futhi ibe negalelo ekukhuthazeni uhlaza, ikhabhoni ephansi kanye ukuthuthukiswa kwamandla esimeme.
