1. SF6 kinoeahale hoʻokuʻu ʻia
SF6 kinoea insulated substation (GIS) he lehulehuSF6 kinoeahui pū ʻia i loko o kahi pā waho, hiki ke piʻi i ka pae pale IP54. Me ka maikaʻi o ka hiki ke hoʻokaʻawale kinoea SF6 (ʻo 100 ka nui o ka haʻihaʻi ʻana o ka arc ma mua o ka ea), hiki ke hana paʻa ke kinoea insulated substation no nā makahiki he 30. Hoʻokomo ʻia nā ʻāpana ola a pau i loko o kahi pahu kila stainless i hoʻopaʻa ʻia i hoʻopiha ʻia meSF6 kinoea. Hiki i kēia hoʻolālā ke hōʻoia e ʻoi aku ka hilinaʻi o ka GIS i ka wā o ke ola lawelawe a koi ʻia ka liʻiliʻi o ka mālama.
Hoʻokumu ʻia ka substation i hoʻopaʻa ʻia i ka uila uila me 11KV a i ʻole 33KV kinoea insulated switchgear. Hiki i kēia mau ʻano ʻelua o ke kinoea insulated substation ke hoʻokō i nā koi noi o ka hapa nui o nā papahana.
Hoʻohana maʻamau ʻo GIS gas insulated switchgear station i ka hoʻolālā hoʻolālā waiwai a paʻa i ka wā o ke kūkulu ʻana, no laila ʻo nā mea maikaʻi o ka substation GIS penei:
Hoʻohālikelike ʻia me ka substation switchgear nui maʻamau, noho wale ia i ka hapaʻumi o ka hakahaka. No laila, ʻo GIS gas insulated substation ka koho maikaʻi loa no nā papahana me kahi liʻiliʻi a me ka hoʻolālā paʻa.
2. Mai kaSF6 kinoeaaia i loko o ka pahu i hoʻopaʻa ʻia, e hana nā ʻāpana substation i hoʻopaʻa ʻia i ke kinoea ma kahi kūlana paʻa, a ʻoi aku ka liʻiliʻi o nā hemahema ma mua o ka substation i hoʻopaʻa ʻia i ka ea.
3. ʻO ka hana hilinaʻi a me ka mālama ʻole.
ʻO nā hemahema o ka GIS gas insulated substation:
1. E ʻoi aku ke kumukūʻai ma mua o ka substation maʻamau
2. Ke loaʻa ka hemahema, ʻoi aku ka lōʻihi o ka ʻimi ʻana i ke kumu o ka hemahema a me ka hoʻoponopono ʻana i ka substation GIS.
3. Pono e hoʻolako ʻia kēlā me kēia keʻena module me kahiSF6 kinoeakaomi ana e nānā i ke kaomi kinoea. ʻO ka hoʻemi ʻana i ke kaomi kinoea o kēlā me kēia module e alakaʻi i ka hāʻule ʻole o ka substation insulated kinoea holoʻokoʻa.
2. Ka poino o ka sulfur hexafluoride leakage
Hexafluoride sulfur maʻemaʻe (SF6)he kinoea ʻona ʻole a ʻala ʻole. ʻOi aku ka kiʻekiʻe o ke kinoea sulfur hexafluoride ma mua o ka ea. Ma hope o ka leakage, hāʻule ia i kahi pae haʻahaʻa a ʻaʻole maʻalahi ka volatilize. Ma hope o ka hanu ʻia ʻana e ke kino kanaka, e hōʻiliʻili ʻia i loko o ka māmā no ka manawa lōʻihi. ʻAʻole hiki ke hoʻokuʻu ʻia, ka hopena i ka emi ʻana o ka nui o ka māmā, dyspnea koʻikoʻi, ʻeha a me nā hopena ʻino ʻē aʻe. I ka nānā ʻana i ka pōʻino i hana ʻia e ka leaka ʻana o ke kinoea Sf6 sulfur hexafluoride i ke kino o ke kanaka, hāʻawi ka poʻe loea i kēia:
1. ʻO ka Sulfur hexafluoride he mea hoʻohāhā. Ma nā haʻahaʻa kiʻekiʻe, hiki iā ia ke hoʻoulu i ka pilikia o ka hanu, ka uila, ka ʻili polū a me ka mucous membranes, a me nā spasms kino. Ma hope o ka hanu ʻana i ka hui ʻana o 80% sulfur hexafluoride + 20% oxygen no kekahi mau minuke, e ʻike ke kino o ke kanaka i ka numbness o nā lālā a me ka make ma ka asphyxiation.
2. Nā huahana decomposition okinoea hexafluoride sulfurma lalo o ka hana o ka uila arc, e like me sulfur tetrafluoride, sulfur fluoride, sulfur difluoride, thionyl fluoride, sulfuryl difluoride, thionyl tetrafluoride a me hydrofluoric acid, etc.
1. Sulfur tetrafluoride: He kinoea kala ʻole ma ka lumi wela me ka ʻala ʻala. Hiki iā ia ke hoʻohua i ka uahi me ka wai ma ka lewa, he mea ʻino i ka māmā a pili i ka ʻōnaehana hanu. Ua like kona ʻona me ka phosgene.
2. Sulfur fluoride: He kinoea kala ʻole ia ma ka lumi wela, ʻawaʻawa, he ʻala ʻala, a he hopena pōʻino e like me ka phosgene i ka ʻōnaehana hanu.
3. Sulfur difluoride: ʻAʻole paʻa loa nā waiwai kemika, a ʻoi aku ka ikaika o ka hana ma hope o ka hoʻomehana ʻana, a maʻalahi ka hydrolyzed i ka sulfur, sulfur dioxide a me ka waika hydrofluoric.
4. Thionyl fluoride: He kinoea waihoʻoluʻu ʻole, ʻala i nā hua popopo, loaʻa nā waiwai kemika paʻa, a he kinoea ʻawaʻawa loa ia e hiki ai ke hoʻoulu i ka edema pulmonary koʻikoʻi a hoʻopau i nā holoholona i ka make.
5. Sulfuryl difluoride: He kinoea kala ʻole a ʻala ʻole me nā waiwai kemika paʻa loa. He kinoea ʻawaʻawa hiki ke hoʻoulu i ka spasms. ʻO kona pōʻino, ʻaʻohe ona ʻala a ʻaʻole e hoʻonāukiuki i ka mucosa ihu, no laila e make koke ia ma hope o ka make ʻana.
6. Tetrafluorothionyl: He kinoea waihoʻoluʻu ʻole me ka ʻala ʻala, he mea ʻino ia i ka māmā.
7. Hydrofluoric acid: ʻO ia ka mea ʻino loa i ka waikawa. He hopena hoʻoulu ikaika ia i ka ʻili a me ka mucous membranes, a hiki ke hoʻoulu i ka edema pulmonary a me ka maʻi pneumonia.
Sf6 kinoea hexafluoride sulfurlapaʻau pilikia leakage: e hoʻokuʻu koke i nā limahana mai ka wahi i hoʻohaumia ʻia a hiki i ka makani kiʻekiʻe, a hoʻokaʻawale iā lākou, kaohi loa i ke komo ʻana. Manaʻo ʻia e ʻaʻahu nā limahana hoʻoponopono ulia pōpilikia iā lākou iho i nā mea hana hanu a me nā lole hana maʻamau. E ʻoki i ke kumu o ka leakage e like me ka hiki. ʻO ka ventila kūpono e hoʻolalelale i ka laha. Inā hiki, e hoʻohana koke. Pono e hoʻohana pono ʻia a hoʻohana ʻia ma hope o ka hoʻoponopono ʻana a me ka nānā ʻana.
ʻO kakinoea hexafluoride sulfurhana ike o kaSF6 kinoeaʻike ʻia ka substation insulated e ka sensor SF6. Ke puka mai ka leak a i ʻole ka ratio ma mua o ka maʻamau, ʻo ia ka manawa mua e ʻike ai a hoʻouna aku i kahi alarm ma ka pūnaewele a i ʻole SMS mamao a kelepona paha e hoʻomanaʻo i nā limahana e haʻalele i kahi pōʻino a pale pono i nā pōʻino koʻikoʻi i hoʻokumu ʻia e ka leaka kinoea.
