C4 yoteteza zachilengedwe gasi GIS idayikidwa bwino mu 110 kV substation

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

Malinga ndi nkhani yochokera ku State Grid Shanghai Electric Power Co., Ltd. pa Disembala 5, chida choyamba (chokhazikitsidwa) cha 110 kV C4 chotetezedwa bwino ndi chilengedwe chotsekedwa bwino ndi zida zamagetsi zamagetsi (GIS) ku China chidayamba kugwira ntchito ku Shanghai 110. kV Ningguo Substation. C4 gasi wochezeka ndi chilengedwe GIS ndiye gwero lalikulu la momwe angagwiritsire ntchito zida zosinthira zachilengedwe mu dipatimenti ya zida za State Grid Corporation yaku China. Zida zikagwiritsidwa ntchito, zidzachepetsa kugwiritsa ntchito bwinompweya wa sulfure hexafluoride (SF6), kuchepetsa kutulutsa mpweya wowonjezera kutentha, komanso kulimbikitsa kukwera kwa mpweya wa Neutralization kukwaniritsidwa.

Panthawi yonse ya moyo wa zida za GIS, mpweya watsopano wa C4 wokonda zachilengedwe umalowa m'malo mwachikhalidwempweya wa sulfure hexafluoride, ndipo ntchito yake yotchinjiriza imakhala pafupifupi kuwirikiza kawiri kuposa gasi wa sulfure hexafluoride pansi pa kukanikiza komweko, ndipo imatha kuchepetsa kutulutsa mpweya pafupifupi 100%, kukwaniritsa zosowa za zida zamagetsi zamagetsi. Zofunikira pa Ntchito Yotetezeka.

M'zaka zaposachedwa, pansi pa njira yayikulu ya "carbon neutralization ndi carbon peaking" m'dziko lathu, mphamvu zamagetsi zikusintha kuchoka ku mphamvu yachikhalidwe kupita ku mtundu watsopano wamagetsi, kulimbikitsa mosalekeza R&D ndi luso, ndikulimbikitsa kusintha ndi kukweza. wa mankhwala molunjika wobiriwira ndi wanzeru. Chitani kafukufuku wambiri pakugwiritsa ntchito matekinoloje atsopano a mpweya wowononga chilengedwe kuti muchepetse kugwiritsa ntchitompweya wa sulfure hexafluoridendikuwonetsetsa kudalirika kwa ntchito ya zida zamagetsi. C4 wochezeka zachilengedwe mpweya (perfluoroisobutyronitrile), monga mtundu watsopano wa gasi insulating m'malo sulfure hexafluoride (SF6), imatha kuchepetsa kwambiri kutulutsa mpweya wamagetsi pamagetsi amagetsi m'moyo wonse, kuchepetsa komanso kusapereka msonkho wa kaboni, ndikupewa kupanga ma gridi amagetsi kuti zisatsekeredwe ndi kuchuluka kwa mpweya.

Pa Ogasiti 4, 2022, State Grid Anhui Electric Power Co., Ltd. idachita msonkhano wa C4 woteteza zachilengedwe ku Xuancheng. Gulu loyamba la makabati oteteza zachilengedwe a C4 awonetsetsa ndikugwiritsidwa ntchito ku Xuancheng, Chuzhou, Anhui ndi malo ena. Iwo akhala akugwira ntchito yotetezeka komanso yokhazikika kwa chaka chimodzi, ndipo kudalirika kwa makabati a C4 ring network kwatsimikiziridwa mokwanira. Gao Keli, woyang'anira wamkulu wa China Electric Power Research Institute, adati: "Gulu la polojekitiyi lathetsa mavuto akuluakulu ogwiritsira ntchito gasi wa C4 wosawononga chilengedwe m'makabati a 12 kV ring network. Chotsatira chidzapitiriza kulimbikitsa kugwiritsa ntchito gasi wa C4 wochezeka zachilengedwe m'magulu osiyanasiyana amagetsi ndi zipangizo zamagetsi zosiyanasiyana M'tsogolomu, kugwiritsa ntchito kwakukulu kwa C4 ring unit main unit kudzalimbikitsa kupititsa patsogolo kwa mafakitale otetezera zachilengedwe, kulimbikitsa kusintha kwa mpweya wochepa wa mafakitale amagetsi, ndikupereka zopereka zabwino pakukwaniritsa cholinga cha "carbon double".
