Inductance of coils

A inokosha chaizvo inoshanda kukosha iri nyaya inokosha ine remagetsi induction Fani, yainzi kuzvipira inductance. Saka, kana induction coils anoumba munhu kuitika, zvino panguva imwe chete nayo unovapo uye rinobva nekubudisa iyo kunowedzera kuwedzera kuitika. With kuchinja rinobva nekubudisa coils induces electromotive simba (EMF), izvo Proportional kuti rinobva nekubudisa chinja nokukurumidza.

Sezvo iyi kana kondakita induces ane electromotive simba pacharo, kunonzi kuzvidzora induction. Chiitiko yokuzvidzora inductance mune zvemagetsi nematunhu dzimwe nguva kuenzaniswa kuratidzwa inertia mune hurongwa.

The electromotive simba akanyengera ari induction Coil pasi pokudzora Kuchinja yayo rinobva nekubudisa inonzi kuzvidzora induction electromotive simba.

Maererano nomutemo Lenz vake, panguva yose kukura rinobva nekubudisa yaibata pose pose coils windings, kuzvicheka-vakafurira EMF ari coils chinotungamirwa pamusoro electromotive simba panobva, Rinowanikwawo redunhu ichi uye anofumura kuwedzera kuitika mune coils redunhu.

Kana pari panguva coils zvasvika kugara ukoshi iri rinobva nekubudisa hunoguma kuchinja, uye nokuzvidzora Kutemeswa EMF ari coils kunova razero.
Aine nokuzviremekedza induction, sezvo chero nedanho remagetsi induction, vakafurira electromotive simba Proportional nokumhanya panguva iyo rinobva nekubudisa chokuita redunhu kuburikidza iyo iyezvino Rwako, dzinoshandurwa. Pamwero mukuru rinobva zvinoyerera pasina simbi iri coils Proportional kuti mwero panguva iyo iyezvino kuchinja (ΔI / Δt), generating kuerera.

Saka, pamwero mukuru electromotive simba anozvipira induction kuti unovapo pakati nemunhu ari Proportional kune mwero panguva iyo ano kuchinja mairi.
Kana ukatora tambo maumbirwo zvakasiyana, zvinoitika kuti kuva nhamba imwe kwokuchinja ano, electromotive simba dzokuzvikoshesa induction, zvichiguma vachava zvakasiyana.

Saka, kana isu kutora coils uye kutambanudzira imwe dzokai, ipapo panguva iyoyo mwero uko shanduko ano kunoitika, vaizviita induction electromotive rehondo coils zvichava refu. Izvi imhaka yokuti nerimwe simba mutsetse prinizyvaya coils majana, izvozvo unogadzirira pamwe hombe kangani pane imwe chete loop.

Kuwanda, iyo inechirevo kubatana pakati pakukurumidza magetsi zvichisiyana chuma, uye izvi unovapo Nemusi induction EMF - inductance redunhu.

Regai inductance pamusoro Coil netsamba L; ukuwo kutsamira pamusoro electromotive simba anozvipira induction mwero panguva iyo magetsi nechakatsinhiwa kungaratidzwa kubudikidza mutoo:

E = - L (ΔI / Δt)

pano

U L = (ed.E ˖ dzakabatana. T) / (ed.I)

Vachifunga kuti mu nzira iyi, Δt = 1 wechipiri, ΔI = E 1 ampere uye volt = 1, tinowana:

U L = 1 (mu ˖ chik / zvakanaka)

chikwata ichi inonzi Henry (H).

saka,

1 Ipapo = 1 (mu ˖ chik / zvakanaka)

Saka Henry - ndiye inductance pamusoro coils, izvo kuitika kuchinja 1 ampere paminiti wechipiri excites vaizviita induction electromotive simba akaenzana 1 volt.
Nokuti kuyera inductances duku inoshandiswa thousandths Henry - MH (MH) kana millionths Henry - Uh (Uh).

Uyezve, kazhinji kushandiswa, uye zvimwe chikwata - sendimita inductance, pamwe 1 masendimita = 1000 Uh inductor.

Nokudaro,

1 MH Mr = 1000 = 1.000.000 = 1.000.000.000 Uh masendimita

The inductance of coils tinofanira yaro dzinoverengeka majana, chimiro uye kukura. The zvikuru nhamba muchichinjana vari coils kuzvidzora inductance, zvikuru ayo inductance.

Uyewo, kuti vaizviona inductance, kuti coils inductance inowedzera zvikuru paaivapa ndokuadira chinoumba simbi kana zvimwe rinobva zvinhu.
Large inductance electromagnets vane windings mu emagetsi uye Motors, dunhu akazaruka panguva mwero shanduko Magetsi (ΔI / Δt) zvakakwirira kwazvo windings izvi zvingava guru kuzvidzora induction electromotive simba izvo, kana asina kudziviswa, achaita Kuparara ichitenderera kuputira.
