Igereranya ry'imikorere y'igikoresho cya SF6 gihuza ibikoresho n'icyuma gicana umurongo
Guhindura imikorere ya transfoma idatwara imizigo
Imiterere myinshi y’umutwaro w’igice kinini cy’impeta muri sisitemu yo gukwirakwiza ingufu ni ukugabanya no gufunga transformateur ikwirakwiza. Ubushobozi rusange ni 315-1250 kVA, kandi umuvuduko w’umu ... Kandi switch yo gukurura SF6, bitewe n’imiterere y’amashanyarazi ya gaze ya SF6, iyo arc ikonjeshejwe muri gaze ya SF6, ikomeza gutwara amashanyarazi kugeza ubushyuhe bubaye buke cyane, kandi umuvuduko w’amashanyarazi mbere y’uko zero igera ku muvuduko uba muto, bityo hirindwa imbaraga nyinshi z’amashanyarazi. Kubwibyo, imikorere yo gukoresha switch yo gukurura SF6 mu guca transformer idakurura umuvuduko ni myiza kuruta iya SF6 circuit breaker, kandi SF6 circuit breaker ni nziza kuruta vacuum circuit breaker.
Kurinda imikorere y'imashini zikwirakwiza ibintu (transformers)
Kugira ngo habeho kurinda transformateur zikwirakwiza umuriro, gukoresha SF6 load switch + fuse combination ni ingirakamaro kurusha circuit breakers, kandi rimwe na rimwe ntabwo ishobora no kugira uruhare rufatika mu kurinda. Ikizamini cya short-circuit kigaragaza ko iyo transformateur yinjijwe mu mavuta igabanyijemo umuriro, kugira ngo ikigega cya peteroli kidaturika, ikibazo kigomba gukurwaho mu masegonda 20. Kugabanya agaciro k'amashanyarazi ya short-circuit bishobora kurinda transformateur neza. Igihe cyose cyo gucikamo umuriro kigizwe n'ibice bitatu, igihe cyo kurinda relay + igihe cyo gukora cy'icyuma gihagarika umuriro + igihe cyo gufunga, muri rusange gisaba cycle eshatu (milisegonda 60), bityo ntigishobora kurinda transformateur neza. Ndetse na transformateur zumye ni nziza kuruta gukoresha circuit breakers kubera ko flues zirinda vuba.
Imikorere yo guhuza uburyo bwo kurinda relay
Uburinzi bw'icyuma gihagarika uruziga ku mpera y'umutwe w'umuyoboro w'uruhererekane rw'amashanyarazi (icyuma gihagarika uruziga cya 10kV cyo muri sitasiyo) muri rusange bugomba kuba amasegonda 0 kugira ngo habeho guhagarara vuba, amasegonda 0.5 kugira ngo habeho gushyuha cyane, n'amasegonda 0.5 kugira ngo habeho urukurikirane rwa zeru. Iyo icyuma gihagarika uruziga gikoreshejwe mu gice cy'ingenzi cy'uruhererekane rw'amashanyarazi, nubwo cyaba cyashyizwe ku masegonda 0.5, biragoye kwemeza ko icyuma gihagarika uruziga rw'amashanyarazi cya mbere kidakora mbere bitewe n'uko igihe cy'igikorwa cy'icyuma gihagarika uruziga gikwirakwira. Fuse igabanya umuvuduko w'amashanyarazi ntigira ingaruka ku kugabanuka k'amashanyarazi guterwa n'uruziga rugufi, kandi ishobora gukuraho ikibazo mu gihe gito cyane idateye gusimbuka.
