1. SF6 igesiisikhululo esigqunyiweyo
I-SF6 gas insulated substation (GIS) inezininziSF6 igesiIsixhobo sokutshintsha esigqunyiweyo sidityaniswe kwindawo ebiyelweyo yangaphandle, enokufikelela kwinqanaba lokhuseleko le-IP54. Nge-advanteji ye-SF6 ye-gas insulation capability (i-arc breaking capacity iphindwe ka-100 kunomoya), i-gas insulated substation inokusebenza ngokuzinzileyo ngaphezu kweminyaka engama-30. Zonke iindawo eziphilayo zibekwe kwitanki yentsimbi engenasici evalwe ngokupheleleyo ezaliswe ngayoSF6 igesi. Olu luyilo lunokuqinisekisa ukuba i-GIS inokwethenjelwa ngakumbi ngexesha lobomi benkonzo kwaye ifuna ukugcinwa okuncinci.
Isikhululo sombane esiphakathi segesi esigqunyiweyo senziwa ngokubanzi nge-11KV okanye i-33KV yegesi efakwe i-switchgear. Ezi ntlobo zimbini ze-gas insulated substations zinokuhlangabezana neemfuno zezicelo zeeprojekthi ezininzi.
Isikhululo segesi se-GIS esigqunyiweyo sihlala samkela uyilo loyilo olunoqoqosho kunye nolubambeneyo ngexesha lolwakhiwo, ngoko ke iingenelo zesikhululo se-GIS zimi ngolu hlobo lulandelayo:
Xa kuthelekiswa nesikhululo sesixhobo sokutshintsha ubungakanani obuqhelekileyo, sithatha kuphela isinye kwishumi sesithuba. Ke ngoko, i-GIS gas insulated substation lolona khetho lungcono kwiiprojekthi ezinendawo encinci kunye noyilo oludibeneyo.
2. Ukusukela iSF6 igesiIkwitanki etywiniweyo, amacandelo esikhululo esifakwe igesi egqunyiweyo aya kusebenza kwisimo esizinzileyo, kwaye kuya kubakho ukusilela okumbalwa kunesikhululo esifakwe umoya.
3. Ukusebenza okuthembekileyo kunye nokugcinwa-free.
Ububi besikhululo esifakwe igesi ye-GIS:
1. Iindleko ziya kuba phezulu kunesikhululo esiqhelekileyo
2. Xa ukusilela kusenzeka, kuthatha ixesha elide ukufumana unobangela wokusilela nokulungisa isikhululo se-GIS.
3. Ikhabhinethi yemodyuli nganye mayixhotyiswe ngeSF6 igesiigeyiji yoxinzelelo ukujonga uxinzelelo lwerhasi yangaphakathi. Ukunciphisa uxinzelelo lwegesi kuyo nayiphi na imodyuli kuya kukhokelela ekungaphumeleli kwayo yonke i-gas insulated substation.
2. Umonakalo wokuvuza kwesulfure hexafluoride
I-Sulfur hexafluoride ecocekileyo (SF6)yigesi engeyotyhefu kwaye ayinavumba. Umxhuzulane okhethekileyo wegesi yesulfure hexafluoride ungaphezulu kunowomoya. Emva kokuvuza, iyancipha ukuya kwinqanaba eliphantsi kwaye akukho lula ukuguquguquka. Emva kokuphefumlelwa ngumzimba womntu, iya kuqokelelana emiphungeni ixesha elide. Ukungakwazi ukukhupha, okukhokelela ekunciphiseni umthamo wemiphunga, i-dyspnea enzima, ukuphefumula kunye nezinye iziphumo ezibi. Ngokujonga umonakalo obangelwe kukuvuza kwegesi yesulfure ye-Sf6 ye-hexafluoride emzimbeni womntu, iingcali zinika oku kulandelayo:
1. I-Sulfur hexafluoride yi-arhente yokufuthanisela. Kwiindawo eziphezulu, kunokubangela ubunzima bokuphefumla, ukuphefumla, ulusu oluluhlaza okwesibhakabhaka kunye ne-mucous membranes, kunye ne-spasms yomzimba. Emva kokuphefumla umxube we-80% yesulphur hexafluoride + 20% oksijini imizuzu embalwa, umzimba womntu uya kuba ndindisholo kwamalungu kunye nokufa ngokuphefumla.
2. Iimveliso zokubola zeigesi yesulfure hexafluoridephantsi kwesenzo se-arc yombane, njenge-sulphur tetrafluoride, i-sulphur fluoride, i-sulphur difluoride, i-thionyl fluoride, i-sulfuryl difluoride, i-thionyl tetrafluoride kunye ne-hydrofluoric acid, njl. , Zombini ziyonakalisa kakhulu kwaye zinetyhefu.
1. Sulfur tetrafluoride: Yigesi engenambala kubushushu begumbi kunye nevumba elibi. Inokuvelisa umsi ngokufuma emoyeni, okuyingozi kwimiphunga kwaye kuchaphazela inkqubo yokuphefumla. Ubuthi bayo bulingana nephosgene.
2. I-Sulfur fluoride: Yigesi engenambala kwiqondo lobushushu begumbi, inetyhefu, inevumba elibi, kwaye inesiphumo esiyingozi esifana ne-phosgene kwinkqubo yokuphefumla.
3. I-Sulfur difluoride: Iimpawu zemichiza azinzanga ngokugqithisileyo, kwaye ukusebenza kusebenza ngakumbi emva kokufudumeza, kwaye i-hydrolyzed ngokulula ibe yisulfure, i-sulphur dioxide kunye ne-hydrofluoric acid.
4. I-Thionyl fluoride: Yigesi engenambala, ivumba lamaqanda abolileyo, ineempawu zekhemikhali ezizinzileyo, kwaye yigesi enetyhefu kakhulu enokubangela ukudumba okukhulu kwemiphunga ize ifuthanisele izilwanyana zife.
5. I-Sulfuryl difluoride: Yigesi engenambala nengenavumba eneempawu zekhemikhali ezizinzile kakhulu. Yigesi enetyhefu enokubangela i-spasms. Ingozi yayo kukuba ayinalo iphunga elibukhali kwaye ayiyi kubangela ukucaphuka kwi-mucosa yeempumlo, ngoko ke iya kufa ngokukhawuleza emva kokutyhelwa.
6. I-Tetrafluorothionyl: Yigesi engenambala enevumba elibi, eliyingozi kwimiphunga.
7. I-Hydrofluoric acid: Yeyona nto idlayo kwiasidi. Inempembelelo eyomeleleyo yokuvuselela ulusu kunye ne-mucous membranes, kwaye inokubangela i-pulmonary edema kunye ne-pneumonia.
Sf6 igesi yesulfure hexafluorideukuvuza unyango olungxamisekileyo: khupha abasebenzi kwindawo evuzayo ubase kumoya ophezulu, kwaye ubabeke bodwa, uthintele ngokungqongqo ukufikelela. Kwenziwa isincomo sokuba abasebenzi boncedo olungxamisekileyo banxibe izixhobo zokuphefumla ezizimeleyo kunye nempahla yokusebenza jikelele. Sika umthombo wokuvuza kangangoko. Ukungena komoya okunengqiqo ukukhawulezisa ukusasazwa. Ukuba kunokwenzeka, yisebenzise ngoko nangoko. Izikhongozeli ezivuzayo kufuneka ziphathwe kakuhle kwaye zisetyenziswe emva kokulungiswa nokuhlolwa.
Iigesi yesulfure hexafluorideumsebenzi wokubona weSF6 igesiisitishi esigqunyiweyo sichongiwe yinzwa yeSF6. Xa ukuvuza kwenzeka okanye umlinganiselo udlula umgangatho, okokuqala ufumanisa kwaye uthumela i-alarm kwi-site okanye i-SMS ekude okanye i-alamu yomnxeba ukukhumbuza abasebenzi ukuba bahambe kwindawo enobungozi kwaye bathintele ngokufanelekileyo Umonakalo omkhulu obangelwa ukuvuza kwegesi.
