Gasi wa C4 woteteza chilengedwe wayamba kugwira ntchito bwino mu siteshoni yosinthira ya 110 kV

Makina amagetsi aku China agwiritsa ntchito bwino mpweya wa C4 wosawononga chilengedwe (perfluoroisobutyronitrile, wotchedwa C4) kuti ulowe m'malo mwake.mpweya wa sulfure hexafluoride, ndipo ntchitoyi ndi yotetezeka komanso yokhazikika.

Malinga ndi nkhani yochokera ku State Grid Shanghai Electric Power Co., Ltd. pa Disembala 5, chipangizo choyamba (chotchedwa seti) cha 110 kV C4 choteteza chilengedwe chomwe chimateteza mpweya (GIS) ku China chinayamba kugwira ntchito bwino ku Shanghai 110 kV Ningguo Substation. Gasi wa C4 woteteza chilengedwe ndiye njira yofunika kwambiri yogwiritsira ntchito switchgear yoteteza chilengedwe mu dipatimenti ya zida za State Grid Corporation of China. Zidazo zikayamba kugwira ntchito, zimachepetsa kugwiritsa ntchitompweya wa sulfure hexafluoride (SF6), amachepetsa kwambiri mpweya woipa wowononga chilengedwe, ndikuwonjezera kuchuluka kwa mpweya woipa. Cholinga cha Neutralization chomwe chakwaniritsidwa.

Pa nthawi yonse ya moyo wa zida za GIS, mpweya watsopano wa C4 wosawononga chilengedwe umalowa m'malo mwa mpweya wachikhalidwempweya wa sulfure hexafluoride, ndipo mphamvu yake yotetezera kutentha ndi pafupifupi kawiri kuposa mpweya wa sulfure hexafluoride womwe uli ndi mphamvu yomweyo, ndipo imatha kuchepetsa mpweya woipa wa carbon ndi pafupifupi 100%, kukwaniritsa zosowa za zida zamagetsi. Zofunikira pakugwiritsa ntchito bwino.

M'zaka zaposachedwapa, pansi pa njira yayikulu ya "kusatulutsa mpweya woipa komanso kukweza mpweya woipa" m'dziko lathu, makina amagetsi akusintha kuchoka pamakina amagetsi achikhalidwe kupita ku mtundu watsopano wamakina amagetsi, kulimbitsa kafukufuku ndi chitukuko ndi luso, ndikulimbikitsa kusintha ndi kukweza zinthu kuti zikhale zobiriwira komanso zanzeru. Chitani kafukufuku wosiyanasiyana pakugwiritsa ntchito ukadaulo watsopano wa mpweya woteteza chilengedwe kuti muchepetse kugwiritsa ntchitompweya wa sulfure hexafluoridepamene akuonetsetsa kuti zipangizo zamagetsi zikugwira ntchito modalirika. Gasi wa C4 wochezeka ndi chilengedwe (perfluoroisobutyronitrile), monga mtundu watsopano wa gasi woteteza kuti ulowe m'malo mwa sulfure hexafluoride (SF6), zingachepetse kwambiri mpweya woipa wa kaboni wochokera ku zida zamagetsi pa moyo wonse, kuchepetsa ndi kuchotsa msonkho wa kaboni, ndikupewa kuti mapangidwe a gridi zamagetsi asalepheretsedwe ndi kuchuluka kwa mpweya woipa.

Pa Ogasiti 4, 2022, State Grid Anhui Electric Power Co., Ltd. inachita msonkhano wa malo ogwiritsira ntchito makabati a C4 oteteza chilengedwe ku Xuancheng. Gulu loyamba la makabati a C4 oteteza chilengedwe a gasi lawonetsedwa ndikugwiritsidwa ntchito ku Xuancheng, Chuzhou, Anhui ndi malo ena. Akhala akugwira ntchito motetezeka komanso mokhazikika kwa nthawi yoposa chaka chimodzi, ndipo kudalirika kwa makabati a C4 ring network kwatsimikiziridwa mokwanira. Gao Keli, manejala wamkulu wa China Electric Power Research Institute, anati: "Gulu la polojekitiyi lathetsa mavuto akuluakulu a kugwiritsa ntchito gasi wa C4 woteteza chilengedwe m'makabati a 12 kV ring network. Gawo lotsatira lidzapitiliza kulimbikitsa kugwiritsa ntchito gasi wa C4 woteteza chilengedwe m'ma voltage osiyanasiyana ndi zida zosiyanasiyana zamagetsi. M'tsogolomu, kugwiritsa ntchito kwakukulu kwa C4 ring main unit kudzalimbikitsa bwino kukweza makampani a zida zamagetsi oteteza chilengedwe, kulimbikitsa kusintha kwa carbon yochepa m'makampani opanga magetsi, ndikupereka zopereka zabwino pakukwaniritsa cholinga cha "double carbon".
