Inductance of gariiradda

muhiimadda la taaban karo A aad u muhiim ah waa kiis gaar ah oo ah arrin induction electromagnetic, loo yaqaan is-inductance. Sidaas darteed, markii gariiradda induction foomamka hadda, ka dibna isku mar la soo baxdo iyo ka daadanayo magnetic taas oo kordhinaysa la sii kordhaya ee hadda. Iyadoo isbeddelka gariiradda ka daadanayo magnetic xaadiriyaan xoog electromotive (EMF), taas oo saami la xawaaraha isbedel ka daadanayo magnetic.

Tan iyo markii ay dhacdo in this kaari ah xaadiriyaan ciidamo electromotive iniinahoodu ku dhex jiraan, waxa la yidhaahdaa waa is-induction. The arrin is-inductance in wareeggeedii korontada waxaa mararka qaarkood la muujinta tiiro in farsamo marka la barbar dhigo.

Ciidamada electromotive laaluusheen in gariiradda induction ku sarkhaansan iskujoog oo ay ka daadanayo magnetic gaar ah waxaa la yiraahdaa xoog electromotive is-induction.

Sida uu qabo sharciga Lenz ayaa, inta lagu guda jiro koritaanka oo dhan ka daadanayo magnetic permeated windings gariiradda, EMF is-laaluusheen in gariiradda la faray ka dhanka ah il xoog electromotive, waxaa ka mid ahaa in wareeg iyo counteracts korodhka hadda ku soo wareegi jiray gariiradda.

Marka hadda ee gariiradda gaadho qiimaha joogto ah ka daadanayo magnetic joogsanayo in la beddelo, iyo EMF is-laaluusheen in gariiradda uu noqdo eber.
Iyada oo ah is-induction, sida in habka kasta oo induction electromagnetic, laaluusheen xoog electromotive saami la xawaaraha at kaas oo ka daadanayo magnetic lala Bannaanka kaas socodka hadda, waxaa la bedelay. magnitude ee ka daadanayo magnetic maqan yahay bir ah in saami gariiradda in heerka ay hadda isbedel (ΔI / Δt), guud ahaan socodka.

Sayidka, baaxadda ciidanka electromotive is-induction in baxdo kaari ah waa saamiyeed si ay heerka ay isbedel hadda dhexdeeda.
Haddii aad qaadato ee silig of qaabab kala duwan, waxaa soo baxday in isagoo heerka la mid ah oo isbedel ah ee hadda, ciidamada electromotive is-induction, taas oo keentay in uu noqon doono kala duwan.

Sidaas darteed, haddii aanu qaadan gariiradda ka dibna si fidin ka mid markeeda, ka dibna at heerka isla at taas oo isbedel hadda dhacdaa, xoog is-induction ku electromotive of gariiradda noqonaysaa mid dheer. Tan waxa u sabab xaqiiqada ah in line awood kasta oo markooda gariiradda prinizyvaya, waxaa ku lug leh tirada badan oo jeer ka badan hal loop a.

tirada, taas oo lagu tilmaamay xidhiidhka ka dhexeeya xawaaraha oo hadda kala duwan ee silsiladda, iyo this baxdo is-induction EMF - circuit inductance.

Ha inductance ee gariiradda by L jirin qorniinka; halka ku tiirsanaanta ciidamada electromotive heerka is-induction at kaas oo hadda lagu beddelayba waa lagu sheegi karaa by formula soo socda:

E = - L (ΔI / Δt)

halkan

u L = (˖ unugyada ed.E T.) / (Ed.I)

Haddii loo maleeyo in this formula, Δt = 1 labaad, ΔI = E 1 ampere iyo volt = 1, waxaan ka heli:

u L = 1 (ee ˖ sec / si fiican)

Cutubkani waxaa lagu magacaabaa Henry (H).

Sidaa darteed,

1 GN = 1 (ee ˖ sec / si fiican)

Sidaas Henry - waa inductance ee gariiradda, taas oo isbedel hadda of 1 ampere per labaad yididiila galin xoog is-induction ku electromotive siman 1 volt.
Waayo, cabbiraadda inductances yar loo isticmaalo kun ee Henry - MH (MH) ama millionths of Henry - uh (uh).

Intaa waxaa dheer, inta badan loo isticmaalo, iyo kuwa kale ee unugga - inductance centimitir, iyadoo 1 cm = 1000 uh inductor.

Sayidka,

1 MH Mr = 1000 = 1.000.000 = 1.000.000.000 uh cm

inductance ee gariiradda ku xiran yahay ay tirada markooda, qaabka iyo cabbirka. Tirada weyn ee markooda ee gariiradda is-inductance, ee ay inductance weyn.

Sidoo kale, is-inductance, ka gariiradda inductance kordhay xaddi leh marka ay ku soo bandhigid galay muhimka ah ee birta ama qalab kale oo kasta oo magnetic.
electromagnets inductance oo waaweyn ayaa windings ee matoorrada iyo matoorrada, circuit furan mar marka heerka isbedelka ee hadda korontada (ΔI / Δt) waa mid aad u sarreeya ee windings waxaa laga yaabaa badan oo is-induction xoog electromotive oo, haddii aan laga fogaado, ka dhigi doonaa in burburka fuuli jiray madhxiya.
