Gazi ya C4 yo kurengera ibidukikije yashyizwe mu bikorwa neza muri sitasiyo ya 110 kV

Sisitemu y'amashanyarazi y'Ubushinwa yashoboye gukoresha neza gaze ya C4 itangiza ibidukikije (perfluoroisobutyronitrile, izwi nka C4) kugira ngo isimbuzegaze ya hexafluoride ya sulfur, kandi igikorwa kiri mu mutekano kandi gihamye.

Nk’uko amakuru aturuka muri State Grid Shanghai Electric Power Co., Ltd. abivuga ku ya 5 Ukuboza, igikoresho cya mbere (seti) cy’amashanyarazi cya 110 kV C4 cyashyizwe mu bushinwa mu buryo buziguye (GIS) cyashyizwe mu bikorwa neza muri sitasiyo ya Shanghai ya 110 kV Ningguo. Gazi ya C4 ya GIS ni icyerekezo cy’ingenzi cyo gukoresha igerageza ry’ibikoresho biziguye mu bushinwa mu ishami ry’ibikoresho rya State Grid Corporation mu Bushinwa. Nyuma y’uko ibikoresho bishyizwe mu bikorwa, bizagabanya ikoreshwa ryagaze ya hexafluoride ya sulfur (SF6), bigabanya cyane imyuka ihumanya ikirere, kandi byongera imbaraga mu kongera imyuka ihumanya ikirere. Intego yo kugabanya imyuka yangiza ikirere yagezweho.

Mu gihe cyose cy'ubuzima bw'ibikoresho bya GIS, gaze nshya ya C4 itangiza ibidukikije isimbura iya gakondogaze ya hexafluoride ya sulfur, kandi imikorere yayo yo gukingira ikwirakwira inshuro ebyiri ugereranyije na gazi ya hexafluoride ya sulfur iri mu gitutu kimwe, kandi ishobora kugabanya imyuka ihumanya ikirere hafi 100%, ihaza ibyo ibikoresho by'amashanyarazi bikenewe. Ibisabwa mu mikorere myiza.

Mu myaka ya vuba aha, hakurikijwe ingamba zikomeye zo "kugabanya karuboni no kongera ingufu za karuboni" mu gihugu cyacu, uburyo bw'ingufu burimo guhinduka buva ku buryo busanzwe bw'ingufu bujya ku bundi, bukomeza gushimangira ubushakashatsi n'iterambere n'udushya, kandi buteza imbere impinduka no kuvugurura ibicuruzwa mu cyerekezo cy'ibidukikije n'ubwenge. Kora ubushakashatsi ku ikoreshwa ry'ikoranabuhanga rishya ku myuka itangiza ibidukikije kugira ngo ugabanye ikoreshwa ryagaze ya hexafluoride ya sulfurmu gihe hakorwa ibishoboka byose kugira ngo ibikoresho by'amashanyarazi bikore neza. Gazi ya C4 irinda ibidukikije (perfluoroisobutyronitrile), nk'ubwoko bushya bwa gaze irinda ibidukikije isimbura hexafluoride ya sulfur (SF6), bishobora kugabanya cyane imyuka ihumanya ikirere iva mu bikoresho by’amashanyarazi mu gihe cyose cy’ubuzima, kugabanya no gukuraho umusoro ku ruganda rutunganya karuboni, no kwirinda ko iterambere ry’uru ruganda rutunganya karuboni ribangamirwa n’ibipimo by’imyuka ihumanya ikirere.

Ku ya 4 Kanama 2022, State Grid Anhui Electric Power Co., Ltd. yagiranye inama y’umushinga w’akabati k’urusobe rw’amashanyarazi ku bidukikije ka C4 i Xuancheng. Itsinda rya mbere ry’akabati k’urusobe rw’amashanyarazi ku bidukikije ka C4 ryagaragajwe kandi rikoreshwa muri Xuancheng, Chuzhou, Anhui n’ahandi. Kamaze umwaka urenga umwe gakora neza kandi gahamye, kandi ubwizerwe bw’akabati k’urusobe rw’amashanyarazi ka C4 bwaremejwe neza. Gao Keli, umuyobozi mukuru w’Ikigo cy’Ubushakashatsi ku Ngabo z’Amashanyarazi cy’Ubushinwa, yagize ati: “Itsinda ry’umushinga ryakemuye ibibazo by’ingenzi byo gukoresha gaze ya C4 itangiza ibidukikije mu kabati k’urusobe rw’amashanyarazi ka 12 kV. Intambwe ikurikiraho izakomeza guteza imbere ikoreshwa rya gaze ya C4 itangiza ibidukikije mu buryo butandukanye bw’amashanyarazi n’ibikoresho bitandukanye by’amashanyarazi. Mu gihe kizaza, ikoreshwa rikomeye ry’agace ka C4 kazateza imbere cyane inganda z’amashanyarazi zirinda ibidukikije, riteze imbere impinduka mu nganda z’amashanyarazi, kandi ritange umusanzu mwiza mu kugera ku ntego ya “karubone ebyiri”.
