Inductance wa koyilo ndi

A zofunika kwambiri zothandiza kukumbukira nkhani yapadera ya mu atomu chodabwitsa kupatsidwa ulemu, wotchedwa kudziletsa inductance. Choncho, pamene koyilo kupatsidwa ulemu ndipamene ulipo, ndiye imodzi ndi vutolo limachitika ndi kamwazi maginito amene kumawonjezera ndi kuwonjezeka panopa. Ndi kusintha maginito koyilo kamwazi induces electromotive mphamvu (EMF), zomwe ndi njila kwa maginito kamwazi liwiro kusintha.

Popeza Pankhaniyi wochititsa induces mphamvu electromotive palokha, umatchedwa kudziletsa kupatsidwa ulemu. The chodabwitsa cha kudzikonda inductance m'madera magetsi nthawi zina poyerekeza ndi chiwonetsero cha inertia mu zimango.

Mphamvu electromotive anachititsa mu koyilo kupatsidwa ulemu mchikakamizo cha kusintha kwa maginito yake kamwazi amatchedwa kudziletsa kupatsidwa ulemu electromotive mphamvu.

Malinga ndi malamulo Lenz ndi, pamene kukula lonse maginito kamwazi chinamulowerera koyilo windings, kudzikonda anachititsa EMF mu koyilo ndi osiyana ndi electromotive mphamvu gwero, ali m'gulu dera lino ndipo anatchula kuwonjezeka pano mu dera la koyilo.

Pamene masiku ano koyilo ikufika phindu zonse ndi kamwazi maginito ikutha kusintha, ndi kudzikonda anachititsa EMF mu koyilo amakhala ziro.
Ndi kudzikonda kupatsidwa ulemu, monga mwa ndondomeko aliyense wa kupatsidwa ulemu atomu, anachititsa electromotive mphamvu njila kwa liwiro pa zimene kamwazi maginito zogwirizana ndi dera kudzera amene utuluke panopa, lisinthike. Ukulu wa kamwazi maginito, pakalibe chitsulo mu koyilo njila kwa mlingo pa zimene kusintha zikusinthira (ΔI / Δt), kupoletsa otaya.

Motero, ukulu wa mphamvu electromotive wodzilamulira kupatsidwa ulemu kuti ikutuluka wochititsa ndi njila kwa mlingo pa zimene kusintha panopa m'menemo.
Ngati inu kutenga mawaya wamitundu yosiyanasiyana, likukhalira kuti ndi mlingo wofanana wa kusintha panopa, electromotive mphamvu wodzilamulira kupatsidwa ulemu, chifukwa mwa iwo adzakhala osiyana.

Choncho, ngati ife koyilo ndiyeno kutambasula nayenso, ndiye pa mlingo lomwelo limene kusintha panopa limapezeka ndikuvala-kupatsidwa ulemu electromotive mphamvu ya koyilo adzakhala yaitali. Ichi ndi chifukwa chakuti aliyense mphamvu mzere prinizyvaya koyilo motsatana, izo amachita ndi nambala yaikulu ya nthawi kuposa kuzungulira limodzi.

Kuchuluka, amene amadziwika kugwirizanitsa changu chimene panopa zimasiyanasiyana mu unyolo, ndipo n'lakuti kudzipatsa kupatsidwa ulemu EMF - inductance dera.

Lolani inductance wa koyilo ndi kalata L; pamene kudalira pa mphamvu electromotive a mlingo kudziletsa kupatsidwa ulemu pa zomwe masiku ano anasintha tingasonyezere ndi chilinganizo zotsatirazi:

E = - L (ΔI / Δt)

pano

u L = (ed.E ˖ mayunitsi. T) / (ed.I)

Kungoganiza kuti dongosolo lino, Δt = 1 chachiwiri, ΔI = E 1 ampere ndi Volt = 1 timapeza:

u L = 1 (mu ˖ gawo / bwino)

wagawo akutchedwa Henry (H).

Choncho,

1 Gn = 1 (mu ˖ gawo / bwino)

Choncho Henry - ndi inductance wa koyilo, umene kusintha panopa 1 ampere pa mphindi amanditenga kudziona kupatsidwa ulemu electromotive kutithandizanso 1 Volt.
Kuona inductances yaing'ono ntchito thousandths a Henry - mH (mH) kapena miliyoni a Henry - U (U).

Komanso, kambirimbiri, ndipo ena wagawo - centimeter inductance, ndi 1 cm = 1000 U inductor.

Motero,

1 mH Mr = 1000 = 1,000,000 = 1,000,000,000 U masentimita

The inductance wa koyilo ndi amadalira nambala yake motsatana, mawonekedwe ndi kukula. Kwakukulu chiwerengero cha ankasinthana mu koyilo kudziletsa inductance, wamkulu inductance ake.

Komanso, kudziona inductance, ndi koyilo inductance ukuwonjezeka kwambiri powapatsa mu maziko a chitsulo kapena chuma maginito.
Large inductance electromagnets ndi windings mu magudumu ndi Motors, dera lotsegula nthawi imene mlingo wa kusintha kwa magetsi inawadutsa (ΔI / Δt) ndi mkulu mu windings zimenezi zingakhale lalikulu kudziletsa kupatsidwa ulemu electromotive mphamvu yomwe, ngati si kuzipewa, adzachititsa kusokonezeka kumulowetsa kutchinjiriza.
