Thermosetting mode njikọ electromagnetic eriri igwe SB1034/AB310-B

Isi arụmọrụ index nke inductance eriri igwe

1.inductive reactance

Oke nguzogide nke eriri inductance na AC ugbu a ka a na-akpọ inductance XL, yana ohm dị ka unit na ω dị ka akara.Mmekọrịta ya na inductance L na AC ugboro F bụ XL=2πfL.

2.quality factor

Ọdịmma ihe Q bụ ọnụọgụ anụ ahụ na-anọchite anya ogo eriri igwe, yana Q bụ oke nke inductance XL na nguzogide ya, ya bụ, Q = XL/R. inductor na-arụ ọrụ n'okpuru voltaji AC ụfọdụ ugboro.Ọnụ ọgụgụ dị elu nke Q nke inductor, nke dị ntakịrị na-efu ma na-arụ ọrụ nke ọma.Uru q nke eriri igwe jikọtara ya na nguzogide DC nke onye na-eduzi, nkwụsị nke dielectric nke ọkpụkpụ, ọnwụ nke ọta ma ọ bụ isi ígwè kpatara, mmetụta nke mmetụta akpụkpọ anụ dị elu na ihe ndị ọzọ.Uru q nke eriri igwe na-abụkarị iri iri ruo narị otu narị.Ihe dị mma nke inductor jikọtara ya na nguzogide DC nke eriri eriri igwe, ọnwụ dielectric nke eriri igwe na ọnwụ nke isi na ọta kpatara.

3.ekesa ike

Igwe mkpuchi inductance ọ bụla nwere ụfọdụ ikike n'etiti ntụgharị, n'etiti ọkwa, n'etiti eriri igwe na ala ntụaka, n'etiti eriri igwe na ọta magnetik, wdg. A na-akpọ ikike ndị a ikesa nkesa nke eriri inductance.Ọ bụrụ na ejikọta capacitors ndị a kesara ọnụ, ọ na-aghọ ihe nhata capacitor c jikọtara ya na eriri inductance.Ịdị adị nke ikesa ikesa na-ebelata uru Q nke eriri igwe ma na-eme ka nkwụsi ike ya dị njọ, ya mere obere ike nkesa nkesa nke eriri igwe, ka mma.

4.gosiri ugbu a

Ogo nke ugbu a na-ezo aka na uru dị ugbu a nke anaghị ekwe ka inductor gafere mgbe ọ na-arụ ọrụ nke ọma.Ọ bụrụ na ugbu a na-arụ ọrụ karịa nke a na-egosi ugbu a, njirimara arụmọrụ nke inductor ga-agbanwe n'ihi ikpo ọkụ, na ọbụna ọkụ ga-agba ya n'ihi oke ọkụ.

5.allowable mgbanwe

Ndịiche ekwenyere na-ezo aka na mperi a na-anabata n'etiti inductance nke aha ya na inductance n'ezie nke inductor.

Inductor nke a na-ejikarị eme ihe na sekit oscillation ma ọ bụ nzacha na-achọ oke ziri ezi, yana ikike ekwe omume bụ 0.2 [%] ~ 0.5 [%];Otú ọ dị, izi ezi nke coils eji maka njikọ, elu-frequency choke na na adịghị elu;Ngbanwe nke ekwenyere bụ 10 [%] ~ 15 [%].
