1. Igesi ye-SF6isitishi esingaphantsi esigqunyiweyo
Isitishi esingaphantsi kwegesi esigqunywe yi-SF6 (GIS) sinee-multipleIgesi ye-SF6iswitshi esigqunyiweyo sidityaniswe kwindawo evalekileyo yangaphandle, enokufikelela kwinqanaba lokhuseleko lwe-IP54. Ngenxa yenzuzo yokwazi ukuthintela igesi ye-SF6 (umthamo wokuqhekeza i-arc uphindwe kalikhulu kunomoya), isikhululo esigqunyiweyo segesi sinokusebenza ngokuzinzileyo iminyaka engaphezu kwama-30. Zonke iindawo eziphilayo zibekwe kwitanki yentsimbi engagqwaliyo evalekileyo ngokupheleleyo ezalisweIgesi ye-SF6Olu yilo lunokuqinisekisa ukuba i-GIS ithembekile ngakumbi ngexesha lokusebenza kwayo kwaye ayifuni ukugcinwa kakhulu.
Isitishi esingaphantsi komhlaba esigqunywe ngegesi esinombane ophakathi sidla ngokuba neswitshi yegesi eyi-11KV okanye eyi-33KV. Ezi ntlobo zimbini zesitishi esingaphantsi komhlaba esigqunywe ngegesi zinokuhlangabezana neemfuno zesicelo seeprojekthi ezininzi.
Isitishi se-switchgear esigqunywe ngegesi ye-GIS sidla ngokusebenzisa uyilo olungabizi kakhulu noluncinci ngexesha lokwakhiwa, ngoko ke iingenelo zesitishi se-GIS zezi zilandelayo:
Xa kuthelekiswa nesitishi esincinci seswitchgear esinobukhulu obuqhelekileyo, sithatha isinye kwishumi kuphela sendawo. Ke ngoko, isitishi esincinci segesi seGIS silona khetho lufanelekileyo kwiiprojekthi ezinesithuba esincinci kunye noyilo oluncinci.
2. Ukususela okoIgesi ye-SF6xa ikwitanki evaliweyo, izinto zesitishi esingaphantsi esigqunywe ngegesi ziya kusebenza kwimeko ezinzileyo, kwaye kuya kubakho ukusilela okuncinci kakhulu kunesitishi esingaphantsi esigqunywe ngomoya.
3. Ukusebenza okuthembekileyo kunye nokugcinwa kwayo akukho monakalo.
Iingxaki zesitishi esigqunywe ngegesi seGIS:
1. Ixabiso liya kuba phezulu kunesitishi esiqhelekileyo
2. Xa kukho ukusilela, kuthatha ixesha elide ukufumana unobangela wokusilela nokulungisa isikhululo se-GIS.
3. Ikhabhinethi nganye yemodyuli kufuneka ixhotyiswe ngeIgesi ye-SF6igeyiji yoxinzelelo ukuze ijonge uxinzelelo lwegesi lwangaphakathi. Ukunciphisa uxinzelelo lwegesi kuyo nayiphi na imodyuli kuya kukhokelela ekungasebenzini kwesitishi sonke esigqunywe yigesi.
2. Umonakalo wokuvuza kwe-sulfur hexafluoride
I-hexafluoride yesalfure ecocekileyo (SF6)yigesi engenabungozi kwaye ayinavumba. Ubunzima obuthile begesi ye-sulfur hexafluoride buphezulu kunobomoya. Emva kokuvuza, iyehla iye kwinqanaba eliphantsi kwaye akulula ukuyikhupha. Emva kokuphefumla ngumzimba womntu, iya kuqokelelana emiphungeni ixesha elide. Ukungakwazi ukuphuma, okubangela ukuncipha kwamandla emiphungeni, ukuphelelwa ngamandla okukhulu, ukufuthaniseka kunye neminye imiphumo emibi. Ngenxa yomonakalo obangelwe kukuvuza kwegesi ye-Sf6 sulfur hexafluoride emzimbeni womntu, iingcali zinika oku kulandelayo:
1. I-sulfur hexafluoride sisithako esifunxayo. Xa ikwizinga eliphezulu, inokubangela ubunzima bokuphefumla, ukuphefumla kancinci, ulusu oluluhlaza kunye ne-mucous membranes, kunye nokuqaqamba komzimba. Emva kokuphefumla umxube we-80% ye-sulfur hexafluoride + 20% yeoksijini imizuzu embalwa, umzimba womntu uya kuba namahlwili emilenze kwanokufa ngenxa yokufunxa.
2. Iimveliso zokubola kwe-igesi yesalfure ye-hexafluoridephantsi kwesenzo se-arc yombane, efana ne-sulfur tetrafluoride, i-sulfur fluoride, i-sulfur difluoride, i-thionyl fluoride, i-sulfuryl difluoride, i-thionyl tetrafluoride kunye ne-hydrofluoric acid, njl.njl., Zombini zirhabaxa kakhulu kwaye ziyingozi.
1. I-tetrafluoride yesulfure: Yigesi engenambala kubushushu begumbi enevumba elibi. Ingavelisa umsi onomphunga emoyeni, oyingozi kwimiphunga kwaye uchaphazela inkqubo yokuphefumla. Ubuthi bayo bulingana nobe-phosgene.
2. I-sulfur fluoride: Yigesi engenambala kubushushu begumbi, inetyhefu, inevumba elibi, kwaye inefuthe elonakalisayo elifana ne-phosgene kwinkqubo yokuphefumla.
3. I-sulfur difluoride: Iipropati zeekhemikhali azizinzanga kakhulu, kwaye ukusebenza kwayo kusebenza ngakumbi emva kokufudumeza, kwaye ifakwa lula kwi-hydrolyzed ibe yi-sulfur, i-sulfur dioxide kunye ne-hydrofluoric acid.
4. I-Thionyl fluoride: Yigesi engenambala, ivumba amaqanda abolileyo, ineempawu zeekhemikhali ezizinzileyo, kwaye yigesi enobuthi kakhulu enokubangela ukudumba okukhulu kwemiphunga kwaye ibulale izilwanyana.
5. I-Sulfuryl difluoride: Yigesi engenambala kwaye ayinavumba kwaye ineempawu zeekhemikhali ezizinzileyo kakhulu. Yigesi enobuthi enokubangela ukuqaqamba. Ingozi yayo kukuba ayinavumba libukhali kwaye ayizukubangela ukurhawuzelelwa kwi-mucosa yempumlo, ngoko ke iya kufa ngokukhawuleza emva kokuba ityiwe.
6. I-Tetrafluorothionyl: Yigesi engenambala enevumba elibi, eliyingozi kwimiphunga.
7. I-Hydrofluoric acid: Yeyona nto irhabaxa kakhulu kwi-asidi. Inefuthe elinamandla lokushukumisa ulusu kunye ne-mucous membranes, kwaye inokubangela ukudumba kwamaphaphu kunye ne-pneumonia.
Igesi ye-hexafluoride yesulfure ye-Sf6unyango olungxamisekileyo lokuvuza: susa ngokukhawuleza abasebenzi kwindawo engcolileyo evuzayo baye emoyeni ophezulu, kwaye ubahlukanise, uthintele ukufikelela ngokungqongqo. Kucetyiswa ukuba abasebenzi be-emergency respiratory banxibe izixhobo zokuphefumla ezizimeleyo kunye neempahla zokusebenza eziqhelekileyo. Sika umthombo wokuvuza kangangoko kunokwenzeka. Umoya ofanelekileyo wokukhawulezisa ukusasazeka. Ukuba kunokwenzeka, sebenzisa ngoko nangoko. Izikhongozeli ezivuzayo kufuneka ziphathwe kakuhle kwaye zisetyenziswe emva kokulungiswa nokuhlolwa.
Iigesi yesalfure ye-hexafluorideumsebenzi wokufumanisa weIgesi ye-SF6Isitishi esifakwe i-insulation sifunyanwa yi-SF6 sensor. Xa kukho ukuvuza okanye umlinganiselo udlula umgangatho, okokuqala sibona kwaye sithumele i-alamu kwindawo okanye i-SMS ekude okanye i-alamu yefowuni ukukhumbuza abasebenzi ukuba bashiye indawo eyingozi kwaye bathintele ngempumelelo ingozi enkulu ebangelwa kukuvuza kwegesi.
