Isilinda Sokuvikela Se-VI Nemishini Yamandla Aphezulu

Njenge-"arc barrier" enkabeni yeziphazamisi ze-vacuum, amasilinda ethu esivikelo aklanywe ngesakhiwo esiyinkimbinkimbi esihlanganisiwe, esihlanganisa ithusi elingena-oxygen emsulwa kakhulu kanye nensimbi engagqwali yezinga elikhethekile. Lokhu kuhlanganiswa kwezinto akulona iphutha: ithusi elingena-oxygen emsulwa kakhulu liletha amandla okuqhuba ugesi amangalisayo kanye nokumunca ukushisa, kuyilapho insimbi engagqwali ekhethekile inikela ekumelaneni okuphezulu nokuguguleka kwe-arc kanye nokuqina kwemishini, okuqinisekisa ukuthi isilinda sesivikelo singamelana nezimo ezimbi kakhulu zokusebenza kwamandla aphezulu.

Ukuze sifinyelele ukunemba okudingekayo kwengxenye ebalulekile kangaka, sisebenzisa izinqubo zokukhiqiza ezithuthukisiwe: ukudweba ngokunemba kuqala kubumba insimbi ibe yisimo esisilinda esifunwayo, kuqinisekiswe ubuqotho besakhiwo kanye nobukhulu bodonga obufanayo, kuyilapho ukugaya okulandelayo kwe-CNC kucwengisisa ubuso bangaphakathi bube yisiphetho esifana nesibuko esinobukhulu obungu-Ra0.4 noma ngaphansi. Lokhu kuphathwa kobuso okucophelelayo kungaphezu kakhulu kwemininingwane yobuhle—kudlala indima ebalulekile ekusebenzeni kwengxenye.

Udonga lwangaphakathi olubushelelezi kakhulu lumunca kahle amandla e-arc, luvimbele ukwakheka kokushisa okweqile okungonakalisa izingxenye ezizungezile. Luphinde lusize ukwenza ukusatshalaliswa kwensimu kagesi ngaphakathi kwe-vacuum interrupter kube okufanayo, kunciphisa ingozi yokuqina kwensimu yendawo okungase kuholele ekuqhekekeni kokufakwa kokushisa. Ngaphezu kwalokho, lobu buso obusezingeni eliphezulu bunciphisa ukunamathela komphunga wensimbi okhiqizwa ngesikhathi sokuphazamiseka kwe-arc, okugcina ukusebenza kokufakwa kokushisa kwe-interrupter ngokuhamba kwesikhathi. Ngokubambisana, lezi zici azigcini nje ngokuthuthukisa ikhono le-vacuum interrupter lokuphazamisa ugesi ngokuphepha nangokuthembekile kodwa futhi zandisa impilo yayo yonke yenkonzo, okwenza amasilinda ethu esivikelo abe yingxenye ebalulekile yezinhlelo zamandla aphezulu.

Ngokuphendula izidingo zemishini yamazinga ahlukene kagesi (12kV-550kV), singenza ngezifiso isakhiwo esihlanganisiwe kusukela emzimbeni wesilinda kuya ku-flange. Ngokwenza ngcono ubukhulu bodonga kanye nomklamo we-diversion groove, siqinisekisa ukuqina kwe-vacuum okuzinzile (izinga lokuvuza ≤1×10⁻⁹Pa・m³/s) ngesikhathi semijikelezo yokushintsha engu-100,000. Sisebenzisa ulwazi lwethu lokukhiqiza olufana nezingxenye eziyinhloko njenge-bellows, ukubekezelelana kokuhlanganiswa phakathi kwesilinda yesihlangu kanye noxhumana nabo, kanye nezinduku zokudonsa ezivikelayo, kulawulwa ngokuqinile ngaphakathi kuka-±0.02mm, okuvumelana ngokuphelele nezimo zokusebenza kwemishini iyonke. Kusukela ekuhlolweni kwe-spectral kwezinto zokusetshenziswa kuya ekutholakaleni kokuvuza kwe-helium mass spectrometry kwemikhiqizo eqediwe, uhlelo lokulawula ikhwalithi yenqubo ephelele luqinisekisa ukuthi yonke imikhiqizo ingamelana nokuhlolwa okunzima kwamandla aphezulu kagesi kanye nama-arcs aqinile, okunikeza ukwesekwa okuvikelekile okuthembekile kwamaphrojekthi afana nama-smart grid kanye nokudluliswa kwamandla aphezulu kakhulu.
