(1) Umugozi w'icyuma gifunga byuzuye wa 35kV SF6 ugomba gushyiramo umugozi wose mu gikoresho cyihariye kiri mu cyumba gito gifunga byuzuye cy'icyuma gifunga byuzuye, kandi ibice byose bigaragara biba bifite ishingiro.
(2) Akabati k'icyuma ka 10kV SF6 gafunze neza (akabati k'umuyoboro w'impeta) gagabanyijemo imiyoboro ishobora gutandukana ifite angle y'iburyo (ifite ishusho y'inkokora) (kuri 200A) n'imiyoboro ishobora gutandukana ifite angle y'iburyo (ikoreshwa cyane cyane kuri 630A)). Hariho kandi umupfundikizo wihariye wo kurinda umupfundikizo w'umugozi, ni ukuvuga umupfundikizo wihariye wo kurinda ukoreshwa mu gutwikira igice cy'umuyoboro.
Umuyoboro w'insinga ukorerwa mu ruganda hamwe n'ibice by'ingenzi, kandi utsinda ikizamini mu ruganda. Umuyoboro w'insinga winjizwa neza mu mwobo wihariye uri mu gice gifunze neza cy'akabati k'imashini, kandi igice cyagaragaye gishyirwa hasi.
2. Guhuza hagati y'icyuma gifunga insinga n'akabati k'imashini
(1) Umuyoboro wa 35kV uhujwe n'udukingirizo twimuka kandi tudahindagurika, kandi umuyoboro wa terefone ushyirwa mu mwobo wabanje w'akabati k'imashini. Umuyoboro uvanywemo burundu imbere mu kabati k'imashini, kandi gushyiraho insinga ntibigira ingaruka ku miterere y'imbere mu kabati k'imashini. Ishusho ya 4-12 ni igishushanyo mbonera cyerekana aho insinga za 35kV zihagarara.
(2) Ibikoresho byo guhuza ibyuma bishobora gutandukana n’inguni y’iburyo muri rusange biberanye n’ibikoresho byo kugaburira transfoma. Umugozi w’amashanyarazi uhuza n’akabati k’imashini ugizwe n’ibice binyerera. Shyira mu buryo butaziguye mu nkunga y’akabati k’imashini unyuze mu nsinga, hanyuma ugahuzwa n’igice cy’amashanyarazi cy’akabati k’imashini. Inkunga iba yakuwe burundu imbere mu kabati k’imashini, kandi gushyiraho insinga ntibigira ingaruka ku miterere y’imbere y’akabati k’imashini.
(3) Umuhuza w’inguni y’iburyo uhuza bolt ya M16 n’imyobo y’imigozi iri ku nkunga y’akabati k’inguni. Inkunga iba yakuwe burundu imbere mu kabati k’inguni, kandi gushyiraho insinga ntibigira ingaruka ku miterere y’imbere mu kabati k’inguni.
1) Inyongeramusaruro y'akabati k'imashini ikoreshwa mu gusimbuza ni ugushyira voltage ku gikoresho cyihariye, no gukora ikizamini cy'amashanyarazi ahagaze ku gice cy'insinga binyuze mu gikoresho gihuza imbere mu kabati k'imashini.
2) Ibikoresho by'insinga bikora ikizamini cy'amashanyarazi ahagarara kuri terminal y'insinga ikoreshwa mu gucomeka. Ntabwo ari ngombwa gutandukanya terminal y'insinga n'akabati k'imashini, kandi bishobora gukorwa ku kabati k'imashini. Kubwibyo, igice cyo guhuza cy'imashini itandukanya umurongo w'akabati k'imashini n'insinga gisabwa kugira ubushobozi bwo kwihanganira amashanyarazi nk'ubw'insinga.
(2) Ibipimo byo kugenzura no gupima amashanyarazi akoreshwa mu gufunga insinga:
Imashini ifunga neza ifite ingamba zo kurinda umutekano zitunganye. Ingamba z'umutekano za mashini ifunga neza zararangiye, zifite inshingano yo gukumira ikoreshwa nabi, bishobora gukumira iyubakwa ry'insinga iyo icyuma cyo hasi kidafunze. Ariko, haracyakenewe kongera ingamba z'umutekano mu gihe cyo kubaka insinga. Dukurikije ibisabwa na DL 409-1991 “Amabwiriza agenga umutekano mu nganda z'amashanyarazi”, iyo ikora ku mugozi, uruziga rugomba kugeragezwa, gusohora, no gusigwa. Ariko, izi nshingano ntizishobora gushyirwa mu bikorwa ku nsinga zihuza mashini ifunga neza. Gusuzuma niba insinga ifite amashanyarazi cyangwa nta mashanyarazi bishobora gushingira gusa ku isuzuma ry'uko mashini ikora, risaba igikoresho cyihariye cyo kugenzura amashanyarazi.
Hamwe n’imikorere ya switchgear n’iy’insinga, igenzura ry’amashanyarazi n’imirimo yo gushyiraho icyuma bizakorwa binyuze muri switchgear.
1) Igenzura ry'amashanyarazi binyuze mu kabati k'amashanyarazi: Igice cy'ibikoresho by'akabati k'amashanyarazi gafunze neza gifite ibikoresho byo kugenzura amashanyarazi, bitsinda igenzura ry'amashanyarazi rya kabiri.
2) Igenzura ry'amashanyarazi binyuze mu gikoresho cyabugenewe cyo kugenzura amashanyarazi: Iyo hakoreshejwe icyuma gifunga neza cya 35kV gifite imiyoboro ya plug-in, uruganda rushobora gutanga igikoresho cyabugenewe cyo kugenzura amashanyarazi kugira ngo rugenzure neza aho insinga zirimo ubusa. Ariko, nyuma yuko icyuma gifunga kimaze gushyirwaho, ntibishoboka gukora isuzuma ry'amashanyarazi ku gice cya terminal cy'insinga. Iyo hakoreshejwe icyuma gifunga cya 10kV, gishobora gukora igenzura ry'amashanyarazi ahantu hagenewe igenzura ry'amashanyarazi binyuze mu bikoresho byihariye byatanzwe nacyo. Ariko, amakuru y'ubu bwoko bw'igikoresho gisuzuma amashanyarazi ntabwo agaragara, kandi imikorere yihariye iterwa n'uburyo ibikoresho byihariye byizewe.
