Nk'ibice by'ingenzi biyobora amashanyarazi muri turbine z'umuyaga, brushes za karuboni zigira uruhare runini mu kohereza ingufu z'amashanyarazi n'ibimenyetso hagati y'ibice bidahagarara n'ibigenda mu buryo buzenguruka. Mu gice cy'imashini ikora icyuma gitera amashanyarazi, zikora nk' "ikiraro cy'amashanyarazi" hagati ya rotor na circuits zidahinduka, mu gihe zinatanga amashanyarazi ahoraho kandi ahamye kuri sisitemu yo kurinda turbine. Gukomera kw'imikorere yazo bigira ingaruka zitaziguye ku mikorere myiza no mu mutekano ya turbine y'umuyaga - gucika intege kwa brushes za karuboni bishobora gutera ibibazo by'uruhererekane nko guhagarika amashanyarazi no kwangirika kw'ibice. Kubwibyo, kumenya neza uburyo bwa siyansi bwo gusimbuza igihe no kubungabunga ni ingenzi cyane.
1. Imikorere isanzwe yo gusimbuza uburoso bwa karuboni
Igihe cyo gukoresha brushes za karuboni ntigihinduka; kigomba kugenwa neza hashingiwe ku miterere y'ibikoresho n'imiterere nyayo y'imikorere. Mu rwego rwo gushyira mu byiciro ibikoresho, brushes za karuboni zishingiye ku muringa, zitanga ubushobozi bukomeye bwo gutwara ariko zigasaza vuba, muri rusange zisabwa gusimburwa buri myaka 1-2. Brushes za karuboni zishingiye ku feza, zifite ubushobozi bwo kudasaza neza no kudahinduka, zishobora kongerwaho igihe cyo gukoresha kugeza ku myaka 3-5. Ariko, iyi ngengabihe ni ingenzi gusa, kandi inshuro nyayo zo gusimbuza ziterwa n'ibintu byinshi: itandukaniro mu miterere ya turbine z'umuyaga (urugero, imizigo itandukanye hagati ya turbine zo mu bwoko bwa megawatt n'iziciriritse), amahame y'imiterere y'abakora generator, ibidukikije bikora (ubushyuhe bwinshi, ubushuhe bwinshi, n'ahantu hari ivumbi byihutisha kwangirika), ikoreshwa rya turbine n'imbaraga z'umuvuduko w'akazi, ubwiza bwo kubungabunga (harimo imiterere y'ubuso bw'impeta, imiterere y'ubuso bw'uburoso, no kudahinduka k'umuvuduko w'impeshyi), hamwe n'urwego rw'ubwiza n'uburyo bw'ibikoresho bya brushes za karuboni ubwabyo. Bityo, igenzura rihoraho rirakora neza mu kwemeza umutekano wa turbine kuruta kwishingikiriza gusa ku ngengabihe zidahinduka.
2. Ibimenyetso by'ingenzi byo kuburira umuntu ku birebana no gusimbuza uburoso bwa karuboni
(1) Ibipimo bigaragara
Imiterere y'uburoso bwa karuboni ni yo shingiro ry'isuzuma. Ubwa mbere, menya impinduka mu burebure: iyo uburoso bwa karuboni bumaze gusaza kugeza ku rugero ntarengwa rwagenwe n'uwabukoze, cyangwa biteganijwe ko bugera kuri uru rwego mbere y'uko ubukora bukurikira bukorwa, bugomba gusimburwa vuba. Ubwa kabiri, reba niba nta byangiritse byo hanze: niba uburoso bwa karuboni bufite imitumba, uduce duto, ibimenyetso byo gushya, cyangwa niba insinga zibuhuza zishyushye cyane kandi zishaje, cyangwa umubiri w'uburoso ukaba warangiritse, bigaragaza ko uburoso bwatakaje ubushobozi bwabwo bwo gukora busanzwe. Byongeye kandi, kwangirika gukabije ni ikindi kimenyetso cy'ingenzi - niba uburoso bumwe na bumwe bwa karuboni bwarashize cyane mu gihe ubundi bugaragaza kwangirika guke, bishobora gutera ikwirakwira ry'amashanyarazi ritaringaniye no gukora nabi, bigatera kwangirika gukomeye. Muri ibyo bihe, uburoso bwose bwa karuboni bugomba gusimburwa.
(2) Imikorere idahwitse
Imikorere idahwitse mu gihe cy'imikorere ya turbine ikunze kuba ifitanye isano no kunanirwa kwa brush ya karuboni. Mu rwego rwo kohereza umuriro, gushyushya cyangwa guterana kw'amashanyarazi ku buryo buhoraho hagati ya brush ya karuboni n'impeta inyerera akenshi bigaragaza ko nta gitutu gihagije cyo gukoraho cyangwa ko uburoso bukabije bwangiritse. Muri icyo gihe, impamvu zishobora kubaho nko gusaza kw'impeta no gusaza kw'impeta inyerera bigomba gusuzumwa. Mu rwego rwo gukora kwa mekanike, urusaku rudasanzwe "rukubita" cyangwa imitingito mu mpeta inyerera cyangwa agace ka brush ya karuboni bishobora guterwa no gukorana kw'uburoso kudatekanye cyangwa kwangirika gukabije, bigatera kwangirika kudasanzwe. Mu rwego rwo gukora neza kw'amashanyarazi, kugabanuka k'ingufu zisohoka za turbine no gukora neza biterwa no kugabanuka k'imikorere y'uburoso bwa karuboni, ibyo bigatuma amashanyarazi adakwirakwira neza.
(3) Ihindagurika ry'ibipimo by'amashanyarazi
Impinduka mu bipimo by'amashanyarazi zishobora kugaragaza neza imiterere y'uburoso bwa karuboni. Iyo turbine ihuye n'ihindagurika mu gusohora ingufu cyangwa kudahuza kw'amashanyarazi, bishobora guterwa no kwiyongera k'ubudahangarwa bw'amashanyarazi buterwa no kwangirika kw'uburoso bwa karuboni, bigatuma umuriro uhagarara. Byongeye kandi, kwiyongera k'ubudahangarwa bw'amashanyarazi aho buhurira hagati y'uburoso bwa karuboni n'impeta ishobora no gutuma ubushyuhe bukora buzamuka ku buryo budasanzwe, bigatuma habaho uruhererekane rubi rw'ubushyuhe bwihuse, bigasaba kuzimya vuba kugira ngo igenzurwe.
(4) Imbonerahamwe ishingiye ku gihe
Mu gihe gisanzwe cyo gukora, impuzandengo y'igihe cy'uburoso bwa karuboni mu byuma bikoresha umuyaga ni amezi 12-18. Nyuma y'iki gihe, nubwo nta kintu kigaragara cyangiritse, uburoso bugomba gushyirwa mu igenzura ry'ingenzi. Ni byiza kubusimbuza kimwe mu gihe cyo kubusana buri gihe kugira ngo hirindwe ko bwangirika butunguranye. Byongeye kandi, amatsinda menshi yo gukora no kubungabunga ashyiramo uburoso bwa karuboni muri gahunda zabo zo kubungabunga buri mwaka cyangwa igice cy'umwaka. Gusimbuza mu buryo bwo kwirinda bifasha kugabanya ibyago byo kudakora—nyuma ya byose, ugereranije n'igiciro gito cya uburoso bwa karuboni ubwabwo, igihe n'ikiguzi cy'abakozi bijyana no guhagarika uburoso bwa karuboni mu kubungabunga (cyane cyane ibikorwa byo mu misozi miremire) biri hejuru cyane.
3. Akamaro k'ingenzi ko gushimangira kubungabunga no gusimbuza uburoso bwa karuboni
Mu ikiguzi cyo gukoresha no kubungabunga turbine z'umuyaga, igihombo cy'igihe cyo gukora bigira uruhare runini. Kubera ko ari ibice bihendutse bishobora gukoreshwa, ubwiza bw'uburoso bwa karuboni bugira ingaruka zitaziguye ku mikorere ya turbine muri rusange. Kwirengagiza ibibazo byo kwangirika kw'uburoso bwa karuboni ntibitera gusa ihindagurika ry'amashanyarazi no kugabanuka k'ubushobozi bwo gukora, ahubwo bishobora no gutera umuriro bitewe no gukora nabi, bigatwika ubuso bw'impeta ihindagurika kandi bigatera kwangirika gukomeye nko gukurura impeta ihindagurika, gufunga, no kudakora neza. Igiciro cyo gusana cyangwa gusimbuza impeta ihindagurika ni kinini cyane kuruta iy'uburoso bwa karuboni ubwabwo. Binyuze mu igenzura rihoraho no gusimbuza buruso za karuboni ku gihe, imikorere ihamye ya turbine ishobora kwemezwa, kwangirika gutunguranye kukagabanuka, kandi igihe cyo gukora cy'ibice by'ingenzi nka slip rings cyongerwa. Mu gihe kirekire, ibi bishobora kugabanya cyane ikiguzi cyo gukora no kubungabunga ndetse n'ingaruka z'umutekano.
4. Inama z'ingenzi zo guhitamo brushes za karuboni zisimbura nziza cyane
Nubwo uburoso bwa karuboni bukoreshwa, guhitamo nabi bishobora gutuma urunigi runanirwa. Kubwibyo, ibintu byingenzi bikurikira bigomba kwibandwaho:
Ubushobozi bw'ibikoresho: Uburoso bwa karuboni bushingiye kuri grafiti nk'ibikoresho by'ibanze, kandi bushyirwa mu byiciro nka silver-grafiti na copper-grafiti hakurikijwe ingano y'ibyuma byongeweho (ifeza, umuringa). Amahitamo agomba gushingira ku bisabwa mu gishushanyo cya moteri ya turbine y'umuyaga (urugero, umutwaro w'amashanyarazi, umuvuduko wo kuzenguruka)—uburoso bwa karuboni bushingiye kuri silveri bukwiriye ibintu byihuta cyane kandi bidasaza cyane, mu gihe uburoso bwa karuboni bushingiye kuri copper bufite akamaro mu kohereza umuriro mwinshi. Bimwe mu bicuruzwa byo mu rwego rwo hejuru byongerwaho inshinge zidasanzwe cyangwa inyongeramusaruro kugira ngo byongere ubushobozi bwo kudasaza no gutwara ubushyuhe, bishobora gutoranywa hakurikijwe ibikenewe mu gihe cy'akazi kagoye.
Ibipimo by'imikorere: Uburoso bwa karuboni bwiza bugomba kugira ubushobozi bwo gukururana buke (kugira ngo ugabanye kwangirika kw'impeta), ubushobozi bwiza bwo gutwara amashanyarazi n'ubushyuhe (kugira ngo wirinde gushyuha cyane), kandi icyarimwe, bugashyiraho "urwego rwiza rwo kwinjira" hamwe n'ibikoresho byo gukurura kugira ngo habeho umutekano mu gufatana.
Ibice bifasha: Umuvuduko w'uburoso bwa karuboni ni ikintu cy'ingenzi bigira ingaruka ku mikorere y'uburoso. Mu gihe cyo gusimbuza uburoso bwa karuboni, imiterere y'uburoso igomba kugenzurwa icyarimwe. Ni byiza guhitamo ibice bisimbura ibihuye n'umuvuduko w'uburoso bw'uruganda rwa mbere, kandi amasoko agomba gushyirwaho itariki yo gukora kugira ngo byorohereze gusimbuza buri gihe hakurikijwe amahame ngenderwaho y'inganda.
Irinde Kutumvikana: Gukoresha uburoso bwa karuboni hamwe n’uburyo butari bwo cyangwa ubuziranenge burabujijwe cyane, kuko ibi bishobora gutera ibibazo nko gukoresha uburoso budakora neza, kwangirika kw’impeta igenda yihuta, no gushyushya kenshi. Muri icyo gihe, irinde gukomeza gukoresha uburoso bwa karuboni bwamaze igihe kirekire, kugira ngo wirinde kwangirika kw’ibice byabwo bidasubirwaho.
Dufite uburambe bw'imyaka myinshi mu gushushanya no gukora ibikoresho bisimburana by'inganda zikoresha ingufu z'umuyaga, hamwe n'ibikoresho bigezweho byo gupima no gusana ibikorwa, dutanga ubwoko bwose bw'uburoso bwa karuboni busimbura turbine z'umuyaga, bukubiyemo ibikoresho bitandukanye nka silver-grafite na copper-grafite, bihuye n'uburyo busanzwe bwa turbine z'umuyaga. Ibicuruzwa byacu ntabwo birimo ingano zisanzwe n'ibipimo byihariye gusa, ahubwo binatanga serivisi zo guhagarara rimwe nko gusana impeta yo gusimbuka no guhindura aho brush ifata, kwemeza ko brush za karuboni zihuye neza na turbine, no gufasha amatsinda ashinzwe ibikorwa no kubungabunga kugabanya ibyago byo kudakora no kwemeza ko turbine z'umuyaga zikora neza kandi zigakora neza igihe kirekire.
