Cov kev cuam tshuam ntawm kev them nyiaj dhau dhau hauv reactive fais fab nyiaj?
May 14, 2025| Capacitor them nyiaj them: Thaum lub catchitor nyiaj, tus muaj peev xwm thiab lub nra tau txuas nrog kev sib txuas. Ib yam li cov hluav taws xob hluav taws xob, thaum lub nra nce, vim yog kev tiv thaiv sab hauv ntawm lub zog hluav taws xob, cov zis hluav taws xob ntawm lub zog hluav taws xob yuav txo qis. Vim tias ob qho kawg ntawm lub capacitor yuav tsum tau tswj hwm qhov qub voltage, uas yog, tus nqi yuav tsum tso ib feem, uas nce sab hauv qab ntawm qhov hluav taws xob. Nov yog lub peev xwm them choj them nqi.
Ntxiv cov nyiaj them confacitors tuaj yeem tiv thaiv qee yam kev cuam tshuam rau lub zog hluav taws xob xaus thiab thauj khoom kawg thaum lub peev xwm loj dhau.
1. Rau lub hwj chim sib tw, tsis hais txog seb lub thauj khoom yog inductive lossis peev xwm, muaj zog yuav tsim tawm thiab nquag poob; Tsis tas yuav siv txoj kev them nyiaj loj heev uas muaj peev xwm them nyiaj loj
2. Txuas ntxiv, yog tias cov neeg them nyiaj tseem ceeb heev, lub zog hluav taws xob muaj peev xwm, thiab vim tias muaj kev hloov kho thiab overcurrent. Thaum muaj mob hnyav, nws yuav ua rau lub zog fais fab cais kom cais lossis ua puas cov khoom siv hluav taws xob. Yog li ntawd, kev them nyiaj ntau dhau yog tsis tso cai rau kev siv fais fab thiab kev noj haus.
Rau cov neeg siv hluav taws xob zoo tib yam, lub zog siv hluav taws xob ntawm {0}}}. 9 yog txaus. Txawm li cas los xij, muaj kwv yees li ib nrab ntawm cov hluav taws xob reactive sib npaug nrog lub zog nquag hauv lub zog hluav taws xob network. Nyob rau lub sijhawm no, lub zog muab hluav taws xob network xav tau los muab hluav taws xob hluav taws xob tam sim no 1.25 zaug ua haujlwm tam sim no kom pab tau lub zog ua haujlwm ib txwm muaj. Qhov no yuav ua rau cov kab poob ntawm lub zog hluav taws xob network los ntawm 56%. Txawm hais tias lub hwj chim muaj txiaj ntsig yog them nyiaj rau 0.95, lub zog reactive tseem suav rau 31% ntawm lub zog nquag. Ntxiv mus, thaum them nyiaj, ntsuas xws li cov reactors series yog noj, yuav tsis muaj resonance lossis amplification ntawm voltage thiab qhov tshwm sim tam sim no.
Yog li ntawd, qhov thiaj li hu ua cov nyiaj tiv thaiv hluav taws xob tam sim no yuav tsum tau nqa tawm kom meej rau sab xis. Yog tias cov nyiaj tau los yog ntau dhau, nws tseem yuav ua rau muaj kev txo qis hauv qhov muaj zog. Yog hais tias nws poob qis dua tus qauv, tus nplua yuav tseem raug yuam. Vim tias kev them nyiaj ntau dhau los txhais tau tias ntau dhau kev muaj peev xwm siv hluav taws xob. Txij li nws yog ntau reactive zog (txawm yog Capective lossis inductive), nws tseem muaj zog ntau.
