Imashini zikoresha imirasire y'izuba ya DC: kugenzura umutekano n'imikorere myiza
Utwuma duto dukoresha imirasire y'izuba (DC circuit breakers) tugira uruhare runini mu mutekano no mu mikorere myiza y’ingufu zikomoka ku mirasire y'izuba. Uko ibura ry’ingufu zikomoka ku mirasire y’izuba rikomeza kwiyongera, akamaro k’ibikoresho byizewe kandi bikora neza mu kurinda imirasire y’izuba ntikagombye kurengwa. Mu isi y’izuba, utwuma duto dukoresha imirasire y’izuba (DC circuit breakers) ni ibintu by’ingenzi bifasha mu gutuma sisitemu za PV zikora neza mu gihe zirinda ingaruka zishobora guterwa n’amashanyarazi.
Sisitemu z'ingufu zikomoka ku mirasire y'izuba zikoresha imirasire y'izuba kugira ngo zihindure imirasire y'izuba mo amashanyarazi. Izi paneli zitanga ingufu z'amashanyarazi zikoresha imirasire y'izuba (DC), zishyirwa mu cyuma gihindura umuriro (AC) zigahindurwamo umuriro usimburana (AC) kugira ngo zikoreshwe mu ngo, mu bigo by'ubucuruzi no mu muyoboro w'amashanyarazi. Muri iki gikorwa cyose, utumashini dukoresha imirasire y'izuba (DC circuit breakers) dukora nk'uburyo bw'ingenzi bwo kurinda umutekano, tukarinda sisitemu umuriro urenze urugero, imirasire migufi, n'ibindi bibazo by'amashanyarazi bishobora kwangiza cyangwa guteza akaga abakozi.
Imwe mu nshingano z'ingenzi za DC circuit breakers mu mikoreshereze y'izuba ni uguhagarika urujya n'uruza rw'amashanyarazi mu gihe habayeho ikibazo cyangwa imikorere idasanzwe. Ibyo bifasha mu gukumira kwangirika kw'imirasire y'izuba, insinga, n'ibindi bice by'iyi sisitemu kandi bigabanya ibyago byo gushya cyangwa gushotora amashanyarazi. Byongeye kandi, DC breakers zifasha abakozi bashinzwe kubungabunga imirasire y'izuba gutandukanya ibice runaka by'imirasire y'izuba kugira ngo bayisane cyangwa bayisane badafunze sisitemu yose.
Hari ibintu byinshi by'ingenzi bigomba kwitabwaho mu guhitamo icyuma gihagarika imirasire ya DC cyo gushyiraho imirasire y'izuba. Ibi birimo imiterere y'amashanyarazi n'ubushyuhe bw'izuba rya paneli na inverter, ubwoko bw'imiterere ya PV array (nk'uruhererekane cyangwa parallel), hamwe n'ibisabwa byihariye mu ikoreshwa. Ni ngombwa guhitamo icyuma gihagarika imirasire ya DC gihuye n'imiterere yihariye ya sisitemu yo gutanga ingufu z'izuba kandi gishobora gutanga uburinzi bwizewe mu bihe bitandukanye by'ibidukikije.
Mu myaka ya vuba aha, iterambere mu ikoranabuhanga rya DC circuit breaker ryatumye habaho ibikoresho byihariye kandi bikora neza byagenewe gukoreshwa ku mirasire y'izuba. Urugero, bimwe mu bikoresho bigabanya imirasire y'izuba byagenewe kwakira ingufu nyinshi z'amashanyarazi n'ubushyuhe busanzwe bufitanye isano n'imirasire y'izuba, mu gihe ibindi bitanga uburyo bwo kurinda ibintu nko kumenya amakosa y'imirasire y'izuba no kuzimya vuba. Ibi bishya ntibinoza gusa umutekano n'ubwizerwe bw'ibikoresho by'izuba, ahubwo binafasha kunoza imikorere n'ubuzima bw'ibikoresho muri rusange.
Byongeye kandi, guhuza imikorere y'ubutasi n'itumanaho muri DC circuit breakers zigezweho bishobora kongera igenzura n'igenzura ry'ishyirwaho ry'izuba. Binyuze mu gukoresha protocole z'itumanaho rya digitale n'ubushobozi bwo gucunga kure, abakora bashobora kubona aho circuit breakers zigeze mu gihe nyacyo, bakamenya ibibazo bishobora kubaho, kandi bagafata ingamba zo kunoza imikorere ya sisitemu. Uru rwego rwo kubona no kugenzura ni ingenzi mu kwemeza ko inganda z'amashanyarazi zikoresha imirasire y'izuba zikora neza no kugabanya igihe cyo kudakora neza bitewe n'ibura ry'amashanyarazi.
Mu gihe impinduka ku isi yose igana ku ngufu zirambye zikomeje, byitezwe ko hazabaho imashini zikoresha imirasire y'izuba zikoresha imirasire y'izuba ziyongera. Abakora n'abatanga serivisi bakomeje kwihatira guhaza iki cyifuzo batanga ibicuruzwa bitandukanye byujuje ibisabwa mu mutekano no mu mikorere y'inganda zikoresha imirasire y'izuba. Byaba ari imirasire y'izuba yo mu ngo, mu bucuruzi cyangwa mu bigo bitanga ingufu z'izuba, uruhare rw'izi mashini zikoresha imirasire y'izuba mu kurinda ubusugire bw'ibikorwa remezo by'amashanyarazi ntirushobora kwirengagizwa.
Muri make, DC circuit breakers ni ingenzi cyane mu mikorere y’amashanyarazi akomoka ku mirasire y’izuba, ikaba irinda impanuka z’amashanyarazi kandi ikubahiriza imikorere myiza kandi yizewe y’ibikoresho bya photovoltaic. Uko ikoranabuhanga rikomeza gutera imbere kandi hibandwa ku ngufu zishobora kongera kwiyongera, iterambere ry’ibisubizo byihariye byo kurinda amashanyarazi akoreshwa ku mirasire y’izuba bizakomeza kugira uruhare runini mu gushyiraho ahazaza ho gutanga amashanyarazi arambye. Mu gushyira imbere guhitamo no gushyira mu bikorwa DC circuit breakers nziza, abafatanyabikorwa mu nganda zikoresha imirasire y’izuba bashobora gukomeza kubahiriza amahame y’umutekano n’imikorere myiza mu gihe batanga umusanzu mu guteza imbere gahunda z’ingufu zisukuye.
