1. SF6 gasinzvimbo inonyungudutswa
Chiteshi chepasi chegesi cheSF6 (GIS) chine akawandaSF6 gasiswitchgear inodzivirirwa yakabatanidzwa muchivako chekunze, iyo inogona kusvika padanho rekudzivirira reIP54. Nekugona kweSF6 gas insulation (kugona kwayo kuputsa arc kwakapetwa ka100 kupfuura mhepo), nzvimbo inodzivirirwa negasi inogona kushanda zvakadzikama kwemakore anopfuura 30. Zvikamu zvese zvipenyu zvinoiswa mutangi resimbi isina tsvina rakavharwa zvizere rakazadzwa neSF6 gasiDhizaini iyi inogona kuve nechokwadi chekuti GIS yakavimbika munguva yebasa uye inoda kugadziriswa kushoma.
Nzvimbo inochengeterwa gasi ine voltage yepakati inowanzo kuve ne switchgear inochengeterwa gasi ye11KV kana 33KV. Mhando mbiri idzi dzenzvimbo dzinochengeterwa gasi dzinogona kusangana nezvinodiwa zvemapurojekiti mazhinji.
Nzvimbo yeGIS inovharwa negesi inowanzoshandisa dhizaini yehurongwa husingadhuri uye hudiki panguva yekuvaka, saka zvakanakira nzvimbo yeGIS ndeizvi:
Kana tichienzanisa ne switchgear substation yakajairika, inongotora chikamu chimwe chete mugumi chenzvimbo yacho. Saka, GIS gas insulated substation ndiyo sarudzo yakanakisisa yemapurojekiti ane nzvimbo diki uye dhizaini diki.
2. Kubva paSF6 gasiKana iri mutangi rakavharwa, zvikamu zvechiteshi chinodzivirirwa negasi zvichashanda zvakanaka, uye pachava nekukundikana kushoma pane chiteshi chinodzivirirwa nemhepo.
3. Kushanda kwakavimbika uye kusachengetedza.
Zvakashata zveGIS gas insulated substation:
1. Mutengo uchave wakakwira kupfuura wepasi penzvimbo yakajairika
2. Kana paine kutadza kushanda, zvinotora nguva yakareba kuti uwane chikonzero chekukundikana uye kugadzirisa GIS substation.
3. Kabhineti yega yega yemodule inofanira kunge yakashongedzerwa neSF6 gasichiyero chekuyera kumanikidzwa kwegasi kuti chitarise kumanikidzwa kwegasi remukati. Kuderedzwa kwekumanikidzwa kwegasi kwemodule chero ipi zvayo kuchaita kuti nzvimbo yese inodzivirirwa negasi isashande zvakanaka.
2. Kukuvara kwekubuda kwesarufa hexafluoride
Sarufa yakachena hexafluoride (SF6)igesi isina chepfu uye isinganhuwi. Huremu hwegasi resulfur hexafluoride hwakakwira kupfuura hwemhepo. Kana yabuda, inonyura kusvika padanho rakaderera uye haisi nyore kuipisa. Kana yafemerwa nemuviri wemunhu, inoungana mumapapu kwenguva yakareba. Kusakwanisa kuburitsa, zvichikonzera kudzikira kwesimba remapapu, kushaya simba kwakanyanya, kudzipwa uye mimwe migumisiro yakaipa. Tichifunga nezvekukuvadzwa kunokonzerwa nekubuda kwegasi reSf6 sulfur hexafluoride mumuviri wemunhu, nyanzvi dzinopa zvinotevera:
1. Sulfur hexafluoride chinhu chinodzipa mweya. Kana chakanyanya, chinogona kukonzera matambudziko ekufema, kufemereka, ganda rebhuruu nemukati memukati, uye kugwinha kwemuviri. Mushure mekufema musanganiswa we80% sulfur hexafluoride + 20% oxygen kwemaminitsi mashoma, muviri wemunhu unonzwa kusanzwa simba kwemakumbo uye kunyange kufa nekuda kwekushaya mweya.
2. Zvigadzirwa zvekuora kwegasi resarufa hexafluoridepasi pekushanda kwemagetsi, zvakaita sesulfur tetrafluoride, sulfur fluoride, sulfur difluoride, thionyl fluoride, sulfurly difluoride, thionyl tetrafluoride uye hydrofluoric acid, nezvimwewo, Zvese izvi zvinoparadza zvakanyanya uye zvine chepfu.
1. Sarufa tetrafluoride: Igasi risina ruvara patembiricha yemumba rine hwema hunorwadza. Rinogona kuburitsa utsi hune hunyoro mumhepo, izvo zvinokuvadza mapapu uye zvinokanganisa kufema. Chepfu yaro yakaenzana neye phosgene.
2. Sulfur fluoride: Igasi risina ruvara patembiricha yemumba, rine chepfu, rine hwema hunorwadza, uye rinokuvadza zvakafanana nephosgene kufema.
3. Sulfur difluoride: Hunhu hwemakemikari hahuna kugadzikana zvakanyanya, uye mashandiro acho anoshanda zvakanyanya mushure mekudziya, uye inonyungudika nyore nyore kuita sarufa, sarufa dioxide uye hydrofluoric acid.
4. Thionyl fluoride: Igasi risina ruvara, rinonhuhwirira mazai akaora, rine makemikari akasimba, uye igasi rine chepfu yakawanda rinogona kukonzera kuzvimba kwakanyanya kwemapapu uye kudzikamisa mhuka kusvika dzafa.
5. Sulfuryl difluoride: Igasi risina ruvara uye harinhuwi rine makemikari akasimba. Igasi rine chepfu rinogona kukonzera kupwanyika. Njodzi yaro ndeyekuti harina hwema hunorwadza uye harizokonzere kutsvuka kwemhino, saka rinowanzo fa nekukurumidza mushure mekuiswa chepfu.
6. Tetrafluorothionyl: Igasi risina ruvara rine hwema hunorwadza, hunokuvadza mapapu.
7. Hydrofluoric acid: Ndiyo inonyanya kukuvadza muviri muacid. Inobatsira zvikuru paganda nemukati meganda, uye inogona kukonzera kuzvimba kwemapapu uye pneumonia.
Sf6 sarufa hexafluoride gasikurapwa kwekukurumidzira kwekubuda kwemvura: bvisa vashandi nekukurumidza kubva munzvimbo ine tsvina yabuda kuenda kumhepo yepamusoro, uye uvaparadzanise, wovarambidza kupinda. Zvinokurudzirwa kuti vashandi vekukurumidzira vapfeke michina yekufema inovapa simba rekufema uye mbatya dzebasa. Cheka panobva mvura zvakanyanya sezvinobvira. Kufefetera kwakanaka kuti kukurumidze kupararira kwemvura. Kana zvichibvira, shandisa nekukurumidza. Magaba anobuda mvura anofanira kubatwa nemazvo uye kushandiswa mushure mekugadzirisa nekuongorora.
Iyogasi resarufa hexafluoridebasa rekuona reSF6 gasiNzvimbo inonyungudutswa inoonekwa neSF6 sensor. Kana paine kubuda kwemvura kana kuti chiyero chinopfuura mwero, kekutanga inoonekwa uye inotumira alarm panzvimbo yacho kana SMS iri kure kana alarm yefoni kuyeuchidza vashandi kuti vabve munzvimbo ine njodzi uye kudzivirira kukuvara kukuru kunokonzerwa nekubuda kwemhepo negasi.
