1. Mpweya wa SF6malo osungiramo zinthu zotenthetsera
Malo osungira mpweya otchedwa SF6 gas insulated substation (GIS) amakhala ndi zinthu zambiriMpweya wa SF6chosinthira magetsi chotetezedwa bwino chomwe chimaphatikizidwa mu mpanda wakunja, chomwe chingafike pamlingo woteteza IP54. Ndi ubwino wa mphamvu yoteteza mpweya wa SF6 (mphamvu yothyola arc ndi nthawi 100 kuposa mpweya), malo osungira mpweya otetezedwa ndi mpweya amatha kugwira ntchito mosasunthika kwa zaka zoposa 30. Ziwalo zonse zamoyo zimayikidwa mu thanki yachitsulo chosapanga dzimbiri yotsekedwa bwino yodzazidwa ndiMpweya wa SF6Kapangidwe kameneka kangatsimikizire kuti GIS ndi yodalirika kwambiri panthawi yonse ya ntchito ndipo imafuna kukonza pang'ono.
Malo osungira mpweya okhala ndi mphamvu yamagetsi yapakati nthawi zambiri amakhala ndi switchgear yosungira mpweya ya 11KV kapena 33KV. Mitundu iwiriyi ya malo osungira mpweya okhala ndi mphamvu yamagetsi imatha kukwaniritsa zofunikira pa ntchito zambiri.
Siteshoni ya switchgear yotetezedwa ndi gasi ya GIS nthawi zambiri imagwiritsa ntchito kapangidwe kake kotsika mtengo komanso kakang'ono panthawi yomanga, kotero ubwino wa siteshoni ya GIS ndi motere:
Poyerekeza ndi malo osinthira magetsi a switchgear omwe ndi a kukula kwabwinobwino, amangotenga gawo limodzi mwa magawo khumi okha a malowo. Chifukwa chake, malo osinthira magetsi a GIS omwe amateteza mpweya ndiye chisankho chabwino kwambiri pamapulojekiti omwe ali ndi malo ochepa komanso kapangidwe kakang'ono.
2. PopezaMpweya wa SF6Ngati ili mu thanki yotsekedwa, zigawo za siteshoni yotetezedwa ndi mpweya zidzagwira ntchito bwino, ndipo padzakhala kulephera kochepa kwambiri kuposa siteshoni yotetezedwa ndi mpweya.
3. Kugwira ntchito kodalirika komanso kopanda kukonza.
Zoyipa za malo osungira mpweya a GIS:
1. Mtengo udzakhala wokwera kuposa malo osinthira zinthu wamba
2. Pakachitika vuto, zimatenga nthawi yayitali kupeza chomwe chachititsa kuti vutolo lithe ndikukonza siteshoni ya GIS.
3. Kabati iliyonse ya module iyenera kukhala ndiMpweya wa SF6choyezera kuthamanga kwa mpweya kuti chiziyang'anira kuthamanga kwa mpweya wamkati. Kuchepetsa kuthamanga kwa mpweya wa gawo lililonse kudzapangitsa kuti malo onse osungira mpweya omwe ali ndi mpweya wotetezedwa ndi mpweya alephereke.
2. Kuipa kwa kutuluka kwa sulfure hexafluoride
Sulphur hexafluoride yoyera (SF6)ndi mpweya wopanda poizoni komanso wopanda fungo. Mphamvu yeniyeni ya mpweya wa sulfure hexafluoride ndi yayikulu kuposa mpweya. Pambuyo potulutsa mpweya, umamira kufika pamlingo wotsika ndipo siwosavuta kuupanga. Pambuyo popumidwa ndi thupi la munthu, umasonkhana m'mapapo kwa nthawi yayitali. Kulephera kutulutsa mpweya, zomwe zimapangitsa kuti mapapo asamagwire bwino ntchito, kupuma movutikira, kupuma movutikira ndi zotsatira zina zoyipa. Poganizira za kuwonongeka komwe kumachitika chifukwa cha kutuluka kwa mpweya wa Sf6 sulfur hexafluoride m'thupi la munthu, akatswiri amapereka izi:
1. Sulfur hexafluoride ndi mankhwala ophera kupuma. Ngati munthu ali ndi mpweya wambiri, angayambitse mavuto opuma, kupuma movutikira, khungu labuluu ndi ma mucous membranes, komanso kupweteka kwa thupi. Mukapuma mpweya wosakaniza wa 80% sulfur hexafluoride + 20% oxygen kwa mphindi zochepa, thupi la munthu lidzamva dzanzi m'miyendo ndipo ngakhale kufa chifukwa cha kupuma movutikira.
2. Zinthu zowola zampweya wa sulfure hexafluoridePogwiritsa ntchito mphamvu ya arc yamagetsi, monga sulfure tetrafluoride, sulfure fluoride, sulfure difluoride, thionyl fluoride, sulfuryl difluoride, thionyl tetrafluoride ndi hydrofluoric acid, ndi zina zotero, zonsezi ndi zowononga kwambiri komanso zoopsa.
1. Sulfure tetrafluorideNdi mpweya wopanda mtundu pa kutentha kwa chipinda wokhala ndi fungo loipa. Ukhoza kutulutsa utsi wokhala ndi chinyezi mumlengalenga, zomwe zimavulaza mapapo ndipo zimakhudza dongosolo la kupuma. Kuopsa kwake kuli kofanana ndi kwa phosgene.
2. Sulfur fluoride: Ndi mpweya wopanda mtundu pa kutentha kwa chipinda, woopsa, uli ndi fungo lopweteka, ndipo umawononga mofanana ndi phosgene m'thupi la munthu.
3. Sulfur difluoride: Kapangidwe ka mankhwala ndi kosakhazikika kwambiri, ndipo magwiridwe antchito ake amakhala ochulukirapo akatenthedwa, ndipo amasungunuka mosavuta kukhala sulfure, sulfure dioxide ndi hydrofluoric acid.
4. Thionyl fluoride: Ndi mpweya wopanda mtundu, fungo la mazira ovunda, uli ndi mphamvu zokhazikika za mankhwala, ndipo ndi mpweya woopsa kwambiri womwe ungayambitse kutupa kwambiri m'mapapo ndikupangitsa nyama kufa.
5. Sulfuryl difluoride: Ndi mpweya wopanda mtundu komanso wopanda fungo wokhala ndi mankhwala okhazikika kwambiri. Ndi mpweya woopsa womwe ungayambitse kupweteka. Kuopsa kwake ndikuti ulibe fungo lopweteka ndipo sungayambitse kuyabwa m'mphuno, kotero nthawi zambiri umafa msanga ukapatsidwa poizoni.
6. Tetrafluorothionyl: Ndi mpweya wopanda mtundu wokhala ndi fungo lopweteka, lomwe ndi loopsa m'mapapo.
7. Hydrofluoric acid: Ndi chinthu chomwe chimawononga kwambiri mu asidi. Chimalimbitsa kwambiri khungu ndi nembanemba ya mucous, ndipo chingayambitse kutupa kwa m'mapapo ndi chibayo.
mpweya wa sulfure wa hexafluoride wa Sf6chithandizo chadzidzidzi chotulutsa mpweya wotuluka: chotsani mwachangu ogwira ntchito pamalo omwe akhudzidwa ndi mpweya wotuluka kupita ku mphepo yamkuntho, ndikuwapatula, ndikuletsa kulowa. Ndikofunikira kuti ogwira ntchito yothandiza anthu mwadzidzidzi azivala zida zopumira zomwe zimathandizira kuti mpweya utuluke komanso zovala zogwirira ntchito. Dulani komwe kumachokera mpweya wotuluka momwe mungathere. Mpweya wabwino wokwanira kuti muchepetse kufalikira kwa mpweya. Ngati n'kotheka, gwiritsani ntchito nthawi yomweyo. Zidebe zotulutsira mpweya ziyenera kusamalidwa bwino ndikugwiritsidwa ntchito mutakonza ndikuwunika.
Thempweya wa sulfure hexafluoridentchito yozindikira yaMpweya wa SF6Chida chosungiramo zinthu zotetezedwa chimazindikirika ndi sensa ya SF6. Pamene kutayikira kwa mpweya kukuchitika kapena chiŵerengerocho chikapitirira muyezo, nthawi yoyamba chimazindikira ndikutumiza alamu pamalopo kapena alamu ya SMS kapena ya foni kuti ikumbutse antchito kuti achoke pamalo oopsa ndikupewa kuwonongeka kwakukulu komwe kumachitika chifukwa cha kutayikira kwa mpweya.
