1. Imiqondo eyisisekelo: Kuyini i-switchgear efakwe igesi?
I-switchgear efakwe igesi (GIS) iyinkimbinkimbi, ubuchwepheshe obuphezulu bokufaka amandla kagesi obusebenzisa Isibabule Hexafluoride (SF6) I-50-70%
Izingxenye ezisemqoka:
- Abaphula umjikelezo: Ukuphazamisa ama-fruit currents usebenzisa i-sf6 gesi junching.
- Ukunqamulwa / ukushintshwa kwezindlebe: Hlukanisa izingxenye zokulungiswa.
- Amabhasi: Yenza okukhona ngaphakathi kwamashubhu afakwe egesi.
- Ukuhlinzwa Abahlanzi: Vikela ekulweni nama-voltage spikes.
- Izinhlelo Zokuqapha igesi: Landelela ingcindezi ye-SF6 kanye nobumsulwa (obucayi beeee C37.122 Ukuthobela).
2. Izicelo: lapho ama-GIS exlels
I-GIS yamukelwa kabanzi ezindaweni lapho isikhala, ukuphepha, noma ukuqina kwesimo sezulu ziza kuqala:
- Amagridi Amandla Amadolobha: Okufakwa emadolobheni afana neTokyo neNew York ancike ku-GIS ukunciphisa izinyawo (ABB, 2023).
- Izitshalo zezimboni: Ukuhlaziywa kwamafutha nezikhungo zedatha zisebenzisa umsebenzi wokusebenza olwa nothuli- kanye nokugqwala.
- Amandla avuselelekayo: Amapulazi omoya asogwini olusogwini uzungeza ukwakheka okuhle kwe-GIS
- Izifunda Eziphakeme: Izakhiwo ezizinzile ze-SF6 ezizinzile ze-Expperform Air ezingcindezini eziphansi (ukuthengiselana, 2021).
3. Izitayela zemakethe & abashayeli
Imakethe ye-Global GIS ilindelwe ukuthi ikhule 6.8% CAGR
- I-SF6 SCASE-Out: Imithetho ye-EU F-GOS kanye namazinga we-IEEE akhuthaza SF6-Mahhala GIS GIS Umoya ohlanzekile gą
- Ukuhlanganiswa kwedijithali: I-GIS enikwe amandla okutholwa ngokutholwa kwegesi ye-real-time kanye nokulondolozwa kokubikezela (i-Nokia, 2023).
- Ukuhlanganiswa okuvuselelekayo: Ama-72% amaphrojekthi amasha elanga / anomoya e-Asia-Pacific Cacisa i-GIS yokuxhumeka kwegridi (i-Mordor intelligence).
4. Ukuqhathanisa kwezobuchwepheshe: GIS VS. AIS
| Parámetro | Uhlobo | I-ais |
|---|---|---|
| Umaka wonyawo enhlabathini | I-10-30% ye-AIS | Isikhala esikhulu sangaphandle esidingekayo |
| Ukuhlalisa | 20-40% aphansi izindleko zokuphila | Ukuhlanza njalo kuyadingeka |
| I-Voltage Range | 72.5 kv - 1,100 kv | Kufika ku-800 kV |
| Ingozi Yezemvelo | Iphrothokholi ye-SF6 | Ukuncika kwegesi okuncane |
Umthombo: Iee Standard C37.12222021
5. Kungani ukhethe i-GIS ngezinye izindlela?
I-GIS Outperforms AIS kanye ne-Hybrid ku:
- Izindawo ezicindezelwe isikhala: Ilungele izindawo ezise-skyscraper noma indawo yezintaba.
- Isimo sezulu esibi kakhulu: Ukuklanywa okuvaliwe kumelana nesifutho sikasawoti, izivunguvungu zesihlabathi, kanye nomswakama (ieema, 2022).
- Ukuphila isikhathi eside: Ukuphila okusebenzayo kweminyaka engama-40 + kusebenza ngokulungiswa okufanele (Schneider Electric Case).
6. Ukuthenga Ukuholwa
Cabanga ngalezi zinto:
- Iklasi leVoltage: 145 kv amasistimu abusa ama-grid asemadolobheni;
- Uhlobo lwegesi: Khetha i-GIS-free GIS uma isebenza ezindaweni ezilawulwayo (EU, California).
- Ukwengamisanisa: Amamojula we-gis ahlanganisiwe anciphise isikhathi somhlangano esizeni ngo-60% (amandla we-hitachi).
- Ukuqinisekiswa: Qinisekisa ukuhambisana ne-IEC 62271-203 noma amakhodi wegridi endawo.
Ithiphu ye-Pro: Umlingani nalabo abanikeze abathengisi Izinsizakalo Zokusebenza Kokuphila, njenge-MITSISUBISHI's GIS Health Check, ukwengeza i-ROI.
7. Ama-FAQs
A: Ikhwalithi yegesi ye-SF6 ihlola njalo eminyakeni engama-3-5;
A: Ama-GIS anamuhla athola kabusha ama-SF6 angu-99% we-SF6 ngezinhlelo ezivaliwe, kanye nezinye izindlela ezinjenge-G³'s G³ Ruce Yehlisa i-GWP nge-99% (GE Grid Solutions).
A: Imiklamo ye-YES-modular ivumela ukuthuthukiswa kwezigaba ngaphandle kokuvalwa okugcwele (Nokia, 2023).
8. I-Authority - Ukuqonda Okusekelwa
- Iee Power Power & Energy Society: Kuncoma i-GIS yokuqina kwamadolobha.
- Iphepha elimhlophe le-ABB: Kuqokomisa ukuncishiswa kokulahleka kwamandla angama-30% kusetshenziswa i-GIS kumanethiwekhi okusabalalisa.
- Wikipedia: Amanani wokutholwa kwe-GIS adlula ama-80% eJapan naseSingapore.
Ngokusebenza kwayo okungenakuqhathaniswa nokuzivumelanisa nezimo, i-GIS ihlala ibaluleke kakhulu ekwakheni ama-grids alungele ikusasa.
Amagama agqamile ngokwemvelo ahlanganiswe: I-Shintsha le-Gas-Insurated, Izakhi ze-GIS, i-SF6-Free GIS, Ukuhanjiswa kwe-High-Voltage, ieee C37.122
