Taw qhia rau Q-tus nqi ntawm series resonance
Q tus nqi yog ib qho ntawm cov txheej txheem rau kev ntsuas cov khoom zoo. Hauv qhov zoo tshaj plaws RLC Circuit Court, Q tus nqi tsis tas yuav siab dua lossis qis dua, tab sis yog tus nqi siv rau kev ntsuas qhov zoo.
Yuav ua li cas txhim kho Q tus nqi
Txhim kho Q tus nqi ntawm koob resonance yog ib txoj haujlwm tseem ceeb uas tuaj yeem ua tiav los ntawm ntau txoj hauv kev. Ua ntej, cov khoom siv hluav taws xob zoo thiab cov xov hlau tuaj yeem siv los txo qis zog. Tsis tas li ntawd, kev tsim cov resonators thiab coils tuaj yeem ua kom zoo kom txo qis impedance thiab poob thiab xyuas kom muaj kev sib txuas hauv Circuit Court. Qhov thib ob, kev ua haujlwm ntawm lub voj voog tuaj yeem ua kom zoo dua los ntawm kev xaiv qhov tsim nyog ua haujlwm kub thiab zaus. Thaum kawg, Siv cov khoom siv hluav taws xob zoo thiab cov khoom siv hluav taws xob kom ntseeg tau tias muaj kev ruaj ntseg thiab kev ntseeg siab ntawm Circuit Court.
Ntxiv rau cov txheej txheem no, muaj lwm cov tswv yim uas tuaj yeem siv los txhim kho qhov resonance Q tus nqi, xws li kev siv cov lus tawm tswv yim los ua kom qhov nce thiab ruaj khov ntawm cov resonators, lossis siv cov khoom siv hluav taws xob ua kom muaj zog ntxiv kom muaj zog tso zis. Tsis tas li ntawd, siv cov teeb liab ua cov thev naus laus zis tuaj yeem ua kom cov teeb liab bandwidth zoo thiab txo qhov cuam tshuam ntawm kev cuam tshuam thiab suab nrov.
Hauv cov ntsiab lus, kev txhim kho Q tus nqi ntawm series resonance yog ib txoj haujlwm nyuaj uas yuav tsum muaj kev xav txog ntau yam hauv Circuit Court thiab kev siv ntau lub tswv yim los ua kom qhov kev ua tau zoo tshaj plaws. Los ntawm kev siv cov khoom siv zoo thiab cov qauv tsim, nrog rau kev siv cov thev naus laus zis tshiab thiab cov txheej txheem, kev ua haujlwm siab dua Q qhov tseem ceeb tuaj yeem ua tiav, yog li txhim kho qhov kev ua tau zoo thiab kev ntseeg siab ntawm Circuit Court. Txawm li cas los xij, nws yuav ua rau cov nqi khiav lag luam ntau dua. Hauv kev ntsuas hluav taws xob, tsis muaj qhov yuav tsum tau tshwj xeeb nce Q tus nqi ntawm cov khoom siv. Piv txwv li, reactive zog them ntawm 1 yog suav tias yog qhov zoo tshaj plaws. Lub sijhawm ntawd, lub zog ntawm lub zog hluav taws xob feem ntau nyob ib puag ncig 0.8, thiab Q tus nqi kuj yog tib txoj cai.
