1. SF6 gasiinsulated substation
SF6 gasi insulated substation (GIS) ine akawandaSF6 gasiinsulated switchgear yakasanganiswa mune yakavharirwa yekunze, iyo inogona kusvika IP54 yekudzivirira level. Iine mukana weSF6 gasi insulation kugona (iyo arc breaking capacity yakapetwa ka100 iyo yemhepo), gasi insulated substation inogona kushanda zvakadzikama kweanopfuura makore makumi matatu. Zvese zvipenyu zvikamu zvinoiswa mutangi rakavharwa zvakazara simbi isina tsvina yakazadzwa nayoSF6 gasi. Iyi dhizaini inogona kuvimbisa kuti GIS inonyanya kuvimbika panguva yehupenyu hwebasa uye inoda kushomeka kwekuchengetedza.
Iyo yepakati voltage gasi insulated substation inowanzo umbwa 11KV kana 33KV gasi insulated switchgear. Aya marudzi maviri egasi insulated substations anogona kusangana nezvinodiwa zvemapurojekiti mazhinji.
GIS gasi insulated switchgear station kazhinji inotora hupfumi uye compact dhizaini panguva yekuvaka, saka zvakanakira zveGIS substation ndezvizvi:
Kuenzaniswa neyakajairwa saizi switchgear substation, inongotora chikamu chimwe chete mugumi chenzvimbo. Naizvozvo, GIS gasi insulated substation ndiyo yakanakisa sarudzo yemapurojekiti ane diki nzvimbo uye compact dhizaini.
2. SezvoSF6 gasiiri mutangi rakavharwa, iyo gasi insulated substation zvikamu zvichashanda munzvimbo yakagadzikana, uye pachave nekutadza kushoma pane iyo air insulated substation.
3. Kuvimbika kuita uye kuchengetedza-pasina.
Zvakaipa zveGIS gasi insulated substation:
1. Mutengo uchave wakakwira pane yakajairika substation
2. Kana kukundikana kuchiitika, zvinotora nguva yakareba kuti uwane chikonzero chekukundikana uye kugadzirisa GIS substation.
3. Imwe neimwe module cabinet inofanirwa kunge ineSF6 gasipressure gauge yekutarisa mukati megasi pressure. Kudzikiswa kwegasi kwechero module kunotungamira mukutadza kweiyo yese gasi insulated substation.
2. Kukuvadza kwe sulfur hexafluoride leakage
Pure sulfur hexafluoride (SF6)igasi risina chepfu uye risinganhuhwi. Iyo chaiyo gravity ye sulfur hexafluoride gasi yakakwirira kupfuura iyo yemhepo. Mushure mekudonha, inonyura kusvika padanho rezasi uye haisi nyore kuputika. Mushure mekufemerwa nemuviri wemunhu, inoungana mumapapu kwenguva yakareba. Kusakwanisa kuburitsa, zvichikonzera kudzikiswa kwemapapu, dyspnea yakaoma, kutadza kufema uye mimwe mhedzisiro yakaipa. Nekuda kwekukuvadza kunokonzerwa nekudonha kweSf6 sulfur hexafluoride gasi kumuviri wemunhu, nyanzvi dzinopa zvinotevera:
1. Sulfur hexafluoride chinhu chinokachidza mweya. Munzvimbo dzakakwirira, zvinogona kukonzera kuoma kwekufema, kufema, ganda rebhuruu uye mucous membranes, uye muviri spasms. Mushure mekufema musanganiswa we80% sulfur hexafluoride + 20% oxygen kwemaminetsi mashoma, muviri wemunhu uchaona kusanzwa kwemakumbo uye kunyange kufa nekufemesa.
2. Zvigadzirwa zvekuora zvesulfur hexafluoride gasipasi pechiito chemagetsi arc, senge sulfur tetrafluoride, sulfur fluoride, sulfur difluoride, thionyl fluoride, sulfuryl difluoride, thionyl tetrafluoride uye hydrofluoric acid, nezvimwe.
1. Sulfur tetrafluoride: Igasi risina ruvara patembiricha yepakamuri rine hwema hunonhuwa. Inogona kuburitsa utsi nehunyoro mumhepo, iyo inokuvadza kumapapu uye inokanganisa hurongwa hwekufema. Kuchetura kwayo kwakafanana neye phosgene.
2. Sulfur fluoride: Igasi risina ruvara patembiricha yemumba, ine chepfu, ine hwema hunonhuwa, uye ine mhedzisiro inokuvadza yakafanana nephosgene kuhurongwa hwekufema.
3. Sulfur difluoride: Zvimiro zvemakemikari hazvina kugadzikana zvakanyanya, uye kushanda kwacho kunowedzera kushanda mushure mekupisa, uye inogadzirwa nyore nyore nehydrolyzed kuva sulfur, sulfur dioxide uye hydrofluoric acid.
4. Thionyl fluoride: Igasi risina ruvara, kunhuhwirira kwemazai akaora, ine zvinhu zvemakemikari akagadzikana, uye igasi rine muchetura zvikuru rinogona kukonzera kuoma kwemapapu uye kuvharidzira mhuka kusvika pakufa.
5. Sulfuryl difluoride: Igasi risina ruvara uye risina kunhuwa rine zvinhu zvakagadzikana zvemakemikari. Igasi rine muchetura rinogona kukonzera spasms. Ngozi yaro ndeyokuti haina kunhuhwirira kwakashata uye haizokonzeri kutsamwa kumhino mucosa, saka inowanzofa nokukurumidza mushure mekuita chepfu.
6. Tetrafluorothionyl: Igasi risina ruvara uye rinonhuwa, rinokuvadza kumapapu.
7. Hydrofluoric acid: Ndiyo inonyanya kupisa muasidhi. Iine simba rinokurudzira paganda uye mucous membranes, uye inogona kukonzera pulmonary edema uye pneumonia.
Sf6 sulfur hexafluoride gasileakage emergency emergency: bvisa vashandi kubva munzvimbo yakasvibiswa uchivaendesa kumhepo yepamusoro, uye wovaparadzanisa, rambidza zvakanyanya kupinda. Zvinokurudzirwa kuti vashandi vekukurumidzira vapfeke ega ega ega ega dhizaini yekufema uye zvipfeko zvebasa zvakajairika. Cheka panobva kuvuza zvakanyanya sezvinobvira. Kufefetera kunonzwisisika kukurumidza kupararira. Kana zvichiita, shandisa pakarepo. Midziyo inodeuka inofanira kubatwa nemazvo uye kushandiswa mushure mekugadzirisa nekuongororwa.
Thesulfur hexafluoride gasikuona basa reSF6 gasiinsulated substation inoonekwa neSF6 sensor. Kana kudonha kukaitika kana chiyero ichidarika mwero, kekutanga painoziva uye kutumira alarm pane-saiti kana kure SMS kana foni alarm yekuyeuchidza vashandi kuti vasiye nzvimbo ine njodzi uye kudzivirira zvinobudirira Kukuvadzwa kwakakomba kunokonzerwa nekubuda kwegasi.
