1. Ibisobanuro n'amahame ya Ku
Uduce twa rukuruzi twa transformers na inductors akenshi tuba dufite agace k'idirishya gashobora guhuzwa, kandi coefficient y'ikoreshwa ry'idirishya Ku isobanurwa nk'igipimo cy'agace nyako gakora neza k'insinga y'umuringa (cyangwa aluminiyumu) ihuzwa n'agace kose k'idirishya ry'ibanze rya rukuruzi. Bigaragazwa nka:
Ku = Ac / Aw, Muri byo, Ac ni agace kose k'insinga izunguruka, naho Aw ni agace k'idirishya ry'ibanze rya rukuruzi. Mu by'ukuri, Ku igaragaza urwego rw'ikoreshwa ry'umwanya w'idirishya ry'ibanze rya rukuruzi. Uko agaciro ka Ku kaba kari hejuru, niko insinga nyinshi zizunguruka zishobora gushyirwa mu mwanya umwe w'idirishya, zishobora gutwara imiyoboro minini no kunoza ubushobozi bwo gutunganya ingufu z'ibice bya rukuruzi.
Isano iri hagati y'agace k'idirishya n'aho rizunguruka rishobora kumvikana neza binyuze mu gishushanyo gikurikira:
2. Uburyo bwo kubara bwa Ku
Kugira ngo ubare Ku, ni ngombwa kugena ukwabyo ubuso bwose bwa Ac y'insinga izunguruka n'agace k'idirishya Aw y'ishingiro rya rukuruzi.
Kumenya: Agace k'idirishya ry'ibanze rya rukuruzi Aw gashobora kuboneka hakoreshejwe gupima uburebure n'ubugari bw'idirishya ry'ibanze rya rukuruzi, hanyuma ukagwiza byombi. Ku miterere isanzwe ya rukuruzi, agace k'idirishya gashobora kandi kuboneka mu buryo butaziguye mu gitabo cy'amakuru cyatanzwe n'uruganda rukora rukuruzi.
Kubara: Ubwa mbere, ni ngombwa gusobanura umubare w'izunguruka N z'umugozi n'agace kanyuramo a k'umugozi umwe. Agace kanyuramo a k'umugozi umwe gashobora kubarwa hakoreshejwe formula y'agace kazengurutse a=π d2/4 hashingiwe ku murambararo w'umugozi d. Bityo, agace kose kanyuramo umugozi ni Ac=N * a. Urugero, niba transformateur ikoresha idirishya rya rukuruzi rifite uburebure bwa mm 50 n'ubugari bwa mm 30, noneho Aw=50 * 30=1500mm2, izunguruka ni 100, kandi insinga ifite umurambararo wa mm 0.5 iratoranywa. Agace kanyuramo umugozi umwe ni a=π * 0.52 ≈ 0.196mm2, Ac=100 * 0.196=19.6mm2, na Ku=19.6/1500 ≈ 0.013
3. Ibintu by'ingenzi bigira ingaruka ku
a. Imiterere y'izunguruka
Uburyo bwo kuzunguruka bufite ingaruka zikomeye kuri Ku. Uburyo bwo kuzunguruka bufite gahunda kandi bunoze bushobora gukoresha neza umwanya w'idirishya ugereranije n'uburyo bwo kuzunguruka butoroshye kandi butateguwe, bityo bikazamura agaciro ka Ku. Urugero, gukoresha uburyo bwo kuzunguruka bwa sandwich (kugabanya kuzunguruka kw'ibanze mo ibice bibiri no kuzunguruka kw'inyongera hagati) ntibishobora gusa kunoza ikwirakwizwa ry'imbaraga za rukuruzi, ahubwo binanoza ikoreshwa ry'umwanya w'idirishya ku rugero runaka.
b. Ibikoresho byo gukingira ubwiza
Kugira ngo habeho imikorere myiza y’amashanyarazi mu bijyanye no gukingira imiyoboro, hagomba gukoreshwa ibikoresho byo gukingira imiyoboro nk’irangi ryo gukingira imiyoboro n’ikaseti yo gukingira imiyoboro. Ariko, ibyo bikoresho byo gukingira imiyoboro bizafata umwanya runaka w’amadirishya. Uko ibikoresho byo gukingira imiyoboro birushaho kuba binini, ni ko umwanya muto usigara ku nsinga, kandi agaciro ka Ku kagabanuka. Kubwibyo, guhitamo ibikoresho byo gukingira imiyoboro bito kandi bifite imikorere myiza mu gihe byujuje ibisabwa mu gukingira imiyoboro ni uburyo bwiza bwo kunoza Ku.
c. Imiterere y'ishingiro rya magnetique
Imiterere itandukanye y'imirongo ya rukuruzi ifite imiterere n'ingano bitandukanye by'amadirishya, ibyo bikaba bishobora no kugira ingaruka ku gaciro ka Ku. Urugero, ugereranije n'imirongo ya rukuruzi ya toroidal, imirongo ya rukuruzi yo mu bwoko bwa E ifite amadirishya asanzwe, bigatuma byoroha kuyizunguza kandi ishobora kugera ku gaciro ka Ku kari hejuru; Nubwo imirongo ya rukuruzi ifite ishusho nk'iy'uruziga ifite ibyiza mu kurinda amashanyarazi n'ibindi bintu, kuyizunguza biragoye, kandi ikoreshwa ry'umwanya w'amadirishya riragoye cyane. Kunoza agaciro ka Ku bihura n'imbogamizi nyinshi.
4. Akamaro ka Ku mu gushushanya ibintu mu buryo bufatika
a. Kongera ubucucike bw'ingufu
Mu rwego rwo gukora ibikoresho bigezweho by’amashanyarazi bito no koroshya ubucucike bw’amashanyarazi, kunoza ubucucike bw’amashanyarazi byabaye intego y’ingenzi. Mu kunoza uburyo Ku ikoreshwa, ubuso bw’insinga zizunguruka bushobora kongerwa mu mwanya muto w’idirishya rito ry’ingufu za rukuruzi, bigatuma imiyoboro minini inyuramo kandi ikanoza ubushobozi bwo gutunganya amashanyarazi bwa transformers na inductors. Muri ubu buryo, hamwe n’ingano imwe, igikoresho gishobora kugera ku musaruro mwinshi w’amashanyarazi kugira ngo gihuze n’izamuka ry’ingufu zikenewe.
b. Kugabanya ibiciro
Kongera Ku mu buryo bukwiye bivuze ko ihererekanya ry'ingufu rimwe rishobora kugerwaho hatabayeho kongera ingano y'ishingiro rya rukuruzi. Ibi bigabanya icyifuzo cy'ishingiro rinini rya rukuruzi kandi bigabanya ikiguzi cy'ishingiro rya rukuruzi. Hagati aho, gukoresha neza amadirishya bishobora no kugabanya gusesagura ibikoresho bizunguruka, bigakomeza kuzigama ikiguzi. Kubwibyo, kunoza Ku ni uburyo bw'ingenzi bwo kuringaniza imikorere n'ikiguzi.
c. Kunoza imikorere yo gukwirakwiza ubushyuhe
Iyo Ku iri hasi, uruziga rusakara gato mu idirishya, bishobora gutuma imbaraga rukuruzi zikwirakwira mu buryo butari bumwe ndetse n'ubushyuhe bukabije. Gukoresha Ku neza no kuzuza neza umwanya w'idirishya mu ruziga bishobora gufasha kunoza ubwinshi bw'imbaraga rukuruzi, kugabanya imbaraga z'amashanyarazi zirwanya umuyaga, kugabanya igihombo cyo mu ruziga, bityo bikongera imikorere yo gukwirakwiza ubushyuhe no kwemeza ko ibikoresho bihoraho.
5. Uburyo n'imikorere byo kunoza Ku
a. Gukoresha ikoranabuhanga rigezweho ryo kuzunguruka
Mu gukoresha ibikoresho bigezweho nka za mashini zizunguruka zikora, uburyo bwo kuzizunguruka bunoze kandi buciriritse bushobora kugerwaho, hirindwa ibibazo byo kudohoka no kudahuza bishobora kubaho mu gihe cyo kuzizunguruka n'intoki, no kunoza neza ikoreshwa ry'umwanya w'amadirishya. Muri icyo gihe, zimwe mu nzira zidasanzwe zo kuzizunguruka, nko kuzizunguruka mu buryo busesuye no kuzizunguruka mu buryo buteye ubwoba, zishobora no kunoza imiterere y'izi zizunguruka no kunoza Ku hakurikijwe ibisabwa byihariye by'igishushanyo.
b. Hitamo insinga zikwiye n'ibikoresho byo gukingira
Mu gukoresha insinga zitwara amashanyarazi menshi, insinga zoroshye zishobora gukoreshwa munsi y’ubushobozi bumwe bwo gutwara kugira ngo hakorwe imizunguruko myinshi mu idirishya no kongera Ac. Muri icyo gihe, ibikoresho bishya byoroshye byo gukingira nk'amafilimi yo gukingira nano biratoranywa kugira ngo birebe ko insinga zigira umusaruro mwiza mu gihe bigabanya umwanya winjizwa n'ibikoresho byo gukingira no kunoza Ku.
c. Gutunganya neza imiterere y'ingirabuzimafatizo za rukuruzi
Hitamo ibice bya rukuruzi bifite imiterere n'ingano bikwiye hashingiwe ku bintu byihariye bikoreshwa n'ibisabwa mu mikorere. Ku bishushanyo bimwe na bimwe bifite ibisabwa byinshi bya Ku, ibice bya rukuruzi byihariye bishobora gufatwa nk'ibigamije kunoza imiterere n'ingano y'idirishya rya rukuruzi kugira ngo bigere ku ngaruka nziza zo gukoresha idirishya.
Igipimo cy’ikoreshwa ry’amadirishya Ku gikurikirana inzira yose yo gushushanya transformer na inductor, bigira ingaruka zikomeye ku mikorere, ikiguzi, n’ubwizerwe bw’ibice bya electromagnetic. Mu gusobanukirwa byimbitse ihame rya Ku, kubara neza agaciro kayo, gusesengura neza ibintu bigira ingaruka, no gukoresha uburyo bwo kunoza, birashoboka gushushanya transformers na inductors zifite imikorere myiza kandi zigabanye ibiciro, bigateza imbere iterambere rihoraho ry’ikoranabuhanga ry’amashanyarazi.
