amakuru

Imirongo ya magnetiki yumurongo ikorwa na coil ntishobora kunyura muri coil ya kabiri, bityo inductance itanga imbaraga za magnetique yamenetse bita inductage inductance. Yerekeza ku gice cya magnetiki flux yatakaye mugihe cyo guhuza ibikorwa bya primaire na secondaire.
Ibisobanuro byinduction yo kumeneka, ibitera inductance yamenetse, kwangirika kwindurwe yamenetse, ibintu byinshi bigira ingaruka kumyuka yamenetse, uburyo nyamukuru bwo kugabanya inductance yamenetse, gupima inductance yamenetse, itandukaniro riri hagati yimyanda yamenetse na magnetiki flux yamenetse.
Ibisobanuro bya Inductance Ibisobanuro
Inductance yamenetse nigice cya magnetiki flux yatakaye mugihe cyo guhuza ibanze nicyiciro cya kabiri cya moteri. Inductance yo kumeneka ya transformateur igomba kuba ko imirongo ya magnetique yingufu zakozwe na coil idashobora kunyura muri coil ya kabiri, bityo inductance itanga imbaraga za magnetique bita inductance.
Impamvu yo kutavunika
Inductance yo kumeneka ibaho kubera ko bimwe mubanze (icyiciro cya kabiri) bitajyanye na secondaire (primaire) binyuze muri core, ariko bigasubira mubanze (secondaire) binyuze mu gufunga ikirere. Umuyoboro w’insinga wikubye inshuro 109 uwo mwuka, mugihe ubwikorezi bwibikoresho bya ferrite bikoreshwa muri transformateur bikubye inshuro 104 gusa umwuka. Kubwibyo, iyo flux ya magnetiki inyuze mumuzunguruko wa magneti ikorwa na ferrite ya ferrite, igice cyacyo kizasohokera mu kirere, kigakora uruziga rukuruzi rwafunze mu kirere, bikaviramo gusohora magneti. Kandi uko imikorere ikora yiyongera, ubwikorezi bwibikoresho bya ferrite bikoreshwa bigabanuka. Kubwibyo, kuri frequency nyinshi, iyi phenomenon iragaragara cyane.
Akaga ko kutavunika
Inductance yamenetse nikimenyetso cyingenzi cyo guhinduranya transformateur, igira ingaruka zikomeye kubipimo byerekana imikorere yo guhindura amashanyarazi. Kubaho kwa inductance yameneka bizabyara ingufu za electromotive mugihe igikoresho cyo guhinduranya kizimye, bikaba byoroshye gutera amashanyarazi arenga kumashanyarazi; inductance yameneka irashobora kandi kuba ifitanye isano na capacitance yagabanijwe mumuzunguruko hamwe nubushobozi bwagabanijwe bwa coil transformateur ikora uruziga runyeganyega, bigatuma uruziga runyeganyega kandi rukwirakwiza ingufu za electromagnetique hanze, bigatera kwivanga kwa electronique.
Ibintu byinshi bigira ingaruka kumurengera
Kuri transformateur ihamye yamaze gukorwa, inductance yo kumeneka ifitanye isano nimpamvu zikurikira: K: coefficient de coiffe, ihwanye ninduction yo kumeneka. Kubintu byoroshye byibanze nicyiciro cya kabiri, fata 3. Niba guhinduranya kwa kabiri hamwe no guhinduranya byambere bikomerekejwe Noneho, fata 0.85, niyo mpamvu uburyo bwo guhinduranya sandwich busabwa, inductance yamenetse igabanuka cyane, birashoboka ko bitarenze 1/3 cya umwimerere. Lmt: Impuzandengo yuburebure bwa buri cyerekezo cyizunguruka kuri skeleton Kubwibyo, abashushanya impinduka bakunda guhitamo intangiriro hamwe nintambwe ndende. Mugihe cyagutse cyane, niko inductance yamenetse. Nibyiza cyane kugabanya inductance yamenetse mugenzura umubare wimpinduka zumuyaga kugeza byibuze. Ingaruka ya inductance ni isano ya kane. Nx: umubare wimpinduka zuzunguruka W: ubugari bwumuzingi Amabati: ubunini bwikwirakwizwa rya bW: ubunini bwimyenda yose ya transformateur yarangiye. Nyamara, uburyo bwo guhinduranya sandwich buzana ibibazo ubushobozi bwa parasitike bwiyongera, imikorere iragabanuka. Ubu bushobozi buterwa nubushobozi butandukanye bwibiceri byegeranye byahujwe hamwe. Iyo switch ihinduwe, ingufu zibitswemo zizarekurwa muburyo bwa spike.
Uburyo nyamukuru bwo kugabanya inductance yamenetse
Ibiceri bifatanye 1. Buri tsinda ryizunguruka rigomba gukomeretsa cyane, kandi rigomba kugabanwa neza. 2. 4 Igikoresho cyo gukingura kigomba kugabanywa kugirango cyuzuze ibisabwa na voltage kandi niba hari umwanya munini, tekereza skeleton ndende kandi ugabanye umubyimba. Niba ari igiceri cyinshi, ikarita yo gukwirakwiza magnetiki ikarita yikurikiranya ryinshi irashobora gukorwa muburyo bumwe. Kugabanya inductance yamenetse, ibanze niyisumbuye irashobora gutandukanywa. Kurugero, igabanijwemo ibice 1/3 → icyiciro cya kabiri 1/2 → primaire 1/3 → icya kabiri 1/2 → primaire 1/3 cyangwa primaire 1/3 → icya kabiri 2/3 → primaire 2/3 → icyiciro cya 1 / 3 nibindi, imbaraga za magnetique ntarengwa imbaraga zigabanuka kugeza kuri 1/9. Nyamara, ibiceri bigabanijwe cyane, inzira yo guhinduranya iragoye, igipimo cyintera hagati yifaranga cyiyongereye, ibintu byuzura biragabanuka, kandi kubuza hagati yambere nayisumbuye biragoye. Mugihe aho ibisohoka ninjiza byinjiza ari bike, inductance yo kumeneka isabwa kuba nto cyane. Kurugero, transformateur ya disiki irashobora gukomeretswa ninsinga ebyiri murwego rumwe. Muri icyo gihe, intoki ya magneti ifite ubugari bunini bwidirishya n'uburebure ikoreshwa, nk'ubwoko bw'inkono, ubwoko bwa RM, na PM icyuma. Oxygene ni magnetique, kuburyo imbaraga za magnetique zumurima mumadirishya ziri hasi cyane, kandi inductance ntoya ishobora kuboneka.
Gupima inductance yamenetse
Inzira rusange yo gupima inductance yamenetse ni ukuzenguruka mugihe gito cya kabiri (primaire), gupima inductance ya primaire (secondaire) ihindagurika, kandi agaciro kivamo induction ni primaire (secondaire) kugeza kumurongo wa kabiri (primaire). Impinduka nziza ya transformateur yameneka ntigomba kurenga 2 ~ 4% yubushakashatsi bwayo bwite. Mugupima inductance yamenetse ya transformateur, ubwiza bwa transformateur burashobora kugenzurwa. Induction yo kumeneka igira ingaruka zikomeye kumuzunguruko kuri radiyo nyinshi. Iyo uhinduye transformateur, inductance yo kumeneka igomba kugabanuka bishoboka. Byinshi mubikorwa bya "sandwich" byibanze (byisumbuye) -icyiciro cya kabiri (primaire) -ibanze (icyiciro cya kabiri) bikoreshwa muguhindura transformateur. kugabanya inductance yamenetse.
Itandukaniro riri hagati yimyanda yamenetse na magnetiki flux yamenetse
Inductance yo kumeneka ni uguhuza hagati yambere niyakabiri mugihe habaye imirongo ibiri cyangwa myinshi, kandi igice cyamazi ya magnetiki ntigihujwe rwose nicyiciro cya kabiri. Igice cya inductance yamenetse ni H, ikorwa na magnetique yamenetse kuva primaire kugeza murwego rwa kabiri. Magnetic flux yamenetse irashobora kuba imwe ihindagurika cyangwa ihindagurika ryinshi, kandi igice cyamazi ya magnetiki yamenetse ntabwo kiri mubyerekezo nyamukuru bya magneti. Igice cya magnetiki flux yamenetse ni Wb. Induction yo kumeneka iterwa na magnetiki flux yamenetse, ariko magnetiki flux yamenetse ntabwo byanze bikunze bitanga inductance.
