Hollow kauj

Lub Hollow kauj muaj cov nyhuv thaiv, thiab tus kheej-inductive electromotive quab yuam nyob rau hauv cov cua tub ntxhais kauj kauj yog ib txwm resistant rau tam sim no hloov nyob rau hauv lub kauj. Lub Hollow coil muaj qhov cuam tshuam rau kev hloov pauv tam sim no, thiab qhov loj ntawm qhov cuam tshuam yog hu ua inductive reactance XL, thiab chav tsev yog ohms. Nws kev sib raug zoo nrog inductor l thiab alternating tam sim no zaus f yog xl =2πfl.

Lub Hollow kauj muaj lub luag haujlwm ntawm kev tuning thiab kev xaiv zaus, thiab Hollow kauj thiab lub capacitor tuaj yeem txuas rau tib lub sijhawm los tsim LC tuning circuit. Ntawd yog, qhov inherent oscillation zaus f{{0}}} ntawm Circuit Court yog sib npaug rau zaus f ntawm lub teeb liab tsis-AC, thiab inductive reactance thiab capacitive reactance ntawm lub voj kuj sib npaug, yog li cov electromagnetic lub zog oscillates rov qab mus rau hauv inductance thiab capacitor, uas yog qhov tshwm sim ntawm lub voj voog LC. Thaum resonating, inductive reactance thiab capacitive reactance ntawm lub Circuit Court yog sib npaug thiab thim rov qab, inductive reactance ntawm tag nrho cov tam sim no ntawm lub voj yog me me, cov nqi tam sim no loj (xa mus rau AC teeb liab ntawm F=" F0"), LC resonant Circuit Court muaj lub luag haujlwm ntawm kev xaiv qhov zaus, thiab tuaj yeem xaiv AC teeb liab ntawm qee zaus F.

Hollow coils feem ntau yog siv nyob rau hauv induction txais tos, tsom, daim npav sib nqus, lub taub hau sib nqus, lub tshuab hluav taws xob siab tam sim no, cov khoom siv hluav taws xob tsawg, kev tswj hwm kev lag luam, cov khoom siv hauv tsev, khoom siv hluav taws xob, SMT mounting, xov tooj ntawm tes, wireless transceivers, hluav taws xob navigators, lub zog. regulators, amplifiers, khoom siv thiab lim thiab lwm yam kev lag luam.

1. Inductance

Lub inductance L yog ib yam ntxwv ntawm lub kauj nws tus kheej, ywj siab ntawm qhov loj ntawm qhov tam sim no. Inductance feem ntau qhia los ntawm ib lub npe tshwj xeeb.

2. Sensory tsis kam

Qhov loj ntawm inductive coil qhov hindrance ntawm AC tam sim no hu ua inductive reactance XL, thiab chav tsev yog ohms.

3. Cov yam ntxwv zoo

Qhov zoo tshaj plaws Q yog lub cev muaj nuj nqis uas sawv cev rau qhov loj ntawm lub kauj, thiab Q yog qhov piv ntawm inductive reactance XL rau nws qhov sib npaug, uas yog: Q=XL/R.

Qhov siab dua Q tus nqi ntawm lub kauj, qhov me dua qhov poob ntawm lub voj. Q tus nqi ntawm cov kauj yog cuam tshuam nrog DC tsis kam ntawm cov hlau, dielectric poob ntawm lub cev pob txha, qhov poob los ntawm cov ntaub thaiv npog lossis cov tub ntxhais hlau, kev cuam tshuam ntawm cov tawv nqaij ntau zaus, thiab lwm yam. Q tus nqi ntawm lub kauj yog feem ntau kaum mus rau pua pua.

4. Distribution capacitance

Lub capacitance tam sim no ntawm lem thiab lem ntawm lub kauj, nruab nrab ntawm lub kauj thiab lub phaj hauv qab, thiab nruab nrab ntawm lub kauj thiab cov ntaub thaiv npog yog hu ua qhov kev faib tawm capacitance. Lub xub ntiag ntawm kev faib capacitance txo qis Q tus nqi ntawm lub kauj thiab deteriorates stability, yog li qhov me dua qhov faib capacitance ntawm lub kauj, qhov zoo dua.
