Akabati k'umuyoboro w'impeta kazwi cyane nka SF6 load switch na SF6 load switch + fuse combination appliance bikoreshwa mu murongo w'umuyoboro w'impeta cyangwa terminal. SF6 load switch ni switch nziza cyane ikoreshwa n'abakoresha benshi mu myaka ya vuba aha. Uretse ibyiza byo kumara igihe kirekire amashanyarazi, imbaraga zikomeye zo gucikamo ibice n'ingufu, ibyiza byayo bidasanzwe ni uko byoroshye kubona imyanya itatu yo gukoreramo (kuri, hanze no hasi), umuyoboro muto (inductance, capacitance) yo gufungura no gucikamo ibice, hamwe n'ubushobozi bukomeye bwo kurwanya ibidukikije bikomeye. Irakwiriye gukwirakwizwa no gukoreshwa mu miyoboro ikwirakwiza ingufu z'amashanyarazi zo mu mijyi no mu byaro.
Akabati k'umuyoboro w'impeta gagabanyijemo ubwoko bubiri: ubushyuhe bw'umwuka n'ubushyuhe bwa SF6. Gakoreshwa mu kugabanya no gufunga umuyoboro w'amashanyarazi, gufungura no guca umuyoboro w'amashanyarazi mugufi n'umuyoboro w'amashanyarazi udatwara umutwaro, no gushyushya umuyoboro w'amashanyarazi uturutse hejuru n'umurongo w'insinga ku ntera runaka. Gafite uruhare mu kugenzura no kurinda, kandi ni igikoresho cy'ingenzi cyo guhinduranya umuriro w'amashanyarazi n'amashanyarazi. Mu mubiri w'akabati, ubushyuhe bw'umutwaro bufite ubushyuhe bw'umwuka bugizwe ahanini n'ubwoko bw'umusaruro wa gaze, ubwoko bw'umuvuduko n'ubwoko bw'imvange. Ubushyuhe bw'umutwaro bufite ubushyuhe bwa SF6 ni ubwoko bwa SF6. Kubera ko gaze ya SF6 ifunze mu gikonoshwa, imvune y'igice ikorwa nayo ntigaragara. Ubushyuhe bw'umutwaro mu kabati k'umuyoboro w'impeta muri rusange busaba sitasiyo eshatu, ni ukuvuga, gukata umutwaro, gutandukanya umuyoboro, bishoboka hakoreshejwe ubutaka. Ubwoko bw'umusaruro wa gaze, ubwoko bw'umuvuduko n'ubushyuhe bw'umutwaro bwa SF6 biroroshye kugeraho sitasiyo eshatu, kandi icyumba cyo kuzimya umuriro w'amashanyarazi gishobora kuvunika gusa, ntigishobora gutandukana, bityo ubushyuhe bw'umuyoboro w'amashanyarazi mbere yo guhindura umutwaro bwongeramo ubushyuhe bwo kwitandukanya, kugira ngo habeho uburyo bwo kwitandukanya.
Ihinduranya ry'umuzigo ni ubwoko bw'igikoresho cyo guhinduranya gifite igikoresho cyoroshye cyo kuzimya umuzigo. Ihinduranya ry'umuzigo rikoresha gaze ya SF6 nk'ubushyuhe n'uburyo bwo kuzimya umuzigo bwitwa SF6 load switch. Rishobora gukoreshwa mu gucana no kuzimya umuzigo no kuzimya umuzigo mwinshi, kandi rishobora no gukoreshwa mu gucana no kuzimya imiyoboro idatwara umuzigo, transformers zidatwara umuzigo na capacitor banks, nibindi. Ihinduranya ry'umuzigo rya biti eshatu rifite imikorere ya on, off and ground rifite imiterere yoroshye kandi ihendutse. Ihinduranya ry'umuzigo gusa ntirishobora gukuraho umuzigo mugufi.
Igikoresho cyo guhuza SF6 load switch + fuse gikoreshwa na SF6 load switch kugira ngo gitware umuvuduko w’amashanyarazi urenze urugero (umuvuduko w’amashanyarazi urenze urugero rwa SF6 load switch uracyari mu rugero rwa switch y’umuvuduko urenze urugero rwa switch y’umuvuduko) n’umuvuduko usanzwe ukora ufunga kandi ucika, kandi bisaba no gutwara "umuvuduko w’amashanyarazi". Fuse z’amashanyarazi menshi zishinzwe kurinda umuvuduko mugufi no kurinda umuvuduko w’amashanyarazi ku ruhande rw’amashanyarazi menshi. Muri iki gihe, itsinda ry’umuvuduko w’amashanyarazi wa SF6 n’amafuru atatu afite triggers, igihe cyose igikorwa icyo ari cyo cyose cya trigger, uburyo bwo guhuza buzatuma switch y’umuvuduko ihinduka mu buryo bwikora mu byiciro bitatu. Guhuza ibyo byombi bishobora kuzuza ibisabwa mu kurinda imikorere ya sisitemu yo gukwirakwiza ingufu mu bihe bisanzwe n’ibisanzwe.
Akabati k'urusobe rw'impeta gashobora kugabanywamo urusobe rw'impeta zo mu nzu n'urusobe rw'impeta zo hanze
Umuyoboro w’imbere mu nzu ukoreshwa mu gukwirakwiza ingufu ku ruhande rw’amashanyarazi menshi. Ugizwe n’akabati k’umurongo winjiye, akabati k’ibipimo, akabati ka PT n’akabati k’isohoka rya transformer. Ku bakoresha ingufu nyinshi, umurongo winjiye ugomba gukoresha akabati k’ingufu ebyiri. Igorofa rya karindwi ryavuze ko “ubu hari abantu bazashyiramo switch na fusion y’akabati k’ingufu nyinshi kitwa ring network cabinet, ahanini biroroshye gutandukanya n’akabati k’ingufu za circuit breaker” ntabwo ari ukuri, akabati k’ingufu za ring network gafite gahunda yo kugabanya amashanyarazi.
Umuyoboro w'ingunguru zo hanze ukoreshwa muri grid y'amashanyarazi yo mu mijyi, hakoreshejwe akabati k'ingunguru gasanzwe ko mu bwoko bwa SF6, ikintu kinini kiranga ubwo bwoko bw'akabati ni uko urwego rwo kurinda ruri hejuru, rushobora gukora IP67, rukwiriye gukoreshwa hanze, kandi rushobora kwinjizwa mu mazi igihe gito. Gahunda y'amashanyarazi yo mu muyoboro w'ingunguru muri rusange ikoresha umuyoboro umwe, umuyoboro umwe usohoka, inshuro ebyiri cyangwa eshatu kugira ngo ukore uruziga rusohoka, ni ukuvuga, gushyiraho uburyo bwo gutanga amashanyarazi mu muyoboro w'ingunguru zo mu ntoki.
Kugira ngo amashanyarazi akomeze kandi akomeze gukoreshwa, hakoreshwa imirongo ibiri yo kwinjiramo kugira ngo haboneke ingufu, ikoze nk'uruziga. Imashini ihindura amashanyarazi ya SF6, sitasiyo 3 (gufunga, gufungura, gufunga), umurongo w'ishami, transformateur.
