Q: How often should GIS undergo maintenance?

A : SF6 gas quality checks every 3–5 years; mechanical inspections every 8–10 years (IEEE C37.122).

Q: Is GIS safe given SF6’s global warming potential?

A : Modern GIS recovers >99% of SF6 via closed-loop systems, and alternatives like GE’s g³ gas reduce GWP by 99% (GE Grid Solutions).

Q: Can GIS be retrofitted into older substations?

A : Yes—modular designs allow phased upgrades without full shutdowns (Siemens, 2023).

Gas-insulated switchgear internal structure showing circuit breakers, busbars, and SF6 gas chambers

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.
Thintwa: 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

Параметр	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).
Сертифкаити: 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

Q: Kufanele kuvame kangakanani ukulungiswa?

A: Ikhwalithi yegesi ye-SF6 ihlola njalo eminyakeni engama-3-5;

Q: Ingabe amandla okufudumeza we-GIs aphephile we-SF6?

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).

Q: Ngabe i-GIS ingavuselelwa kabusha ekuhlosweni okudala?

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
