Kev txiav txim siab ua kom muaj kev sib raug zoo yuav lim thaum lawv tsim los ntawm kev siv lub zog lim dej (APF)?
Jun 24, 2025| Nrog rau kev siv hluav taws xob niaj hnub no, cov khoom siv hluav taws xob ua tsis tau zoo li cas los ua qhov kev ua haujlwm tsis zoo lim lawv tawm?
Kuv {. cov ntsiab lus ntawm cov kev txiav txim siab zoo
Higher-order harmonics refer to electrical signals whose frequencies are integer multiples of the fundamental frequency. For power supply systems with a frequency of 50Hz or 60Hz, the fundamental frequency, higher-order harmonics include 100Hz, 150Hz, 200Hz, etc. These harmonics are generated due to nonlinear loads, such as power electronic devices, frequency conterers, thiab hloov hluav taws xob pab . Thaum cov khoom siv hluav taws xob muaj zog, lawv ua rau cov khoom siv hluav taws xob sib txawv ntawm cov nthwv dej .
Ntau dua kev sib raug zoo tsis tsuas yog txo cov zog hluav taws xob ntawm lub system, tab sis kuj tseem yuav ua rau muaj teeb meem ntawm cov khoom siv tiv thaiv ntau dua, ua rau thawj kauj ruam no.
Ii {. Qhov hauj lwm ua tau zoo thiab kev txwv ntawm APF hauv kev txiav cov kev sib raug zoo
1. Qhov ua tau zoo ntawm APF
Cov kev tshawb fawb tau qhia tau tias ntawm ntau yam kev ua kom zoo nkauj, thib ob, thib ob, tab sis kuj tseem siv tau dav hauv ntau daim teb xws li kev lag luam, lub zog, thiab kev tsim kho, ua rau lub luag haujlwm tseem ceeb hauv kev txhim kho lub zog zoo thiab ua kom muaj kev nyab xeeb ntawm cov khoom .
{{0 {}} kev txwv ntawm APF
Txawm hais tias APF tau ua tiav cov txiaj ntsig zoo tshaj plaws hauv kev ua kom zoo nkauj, hauv cov kev siv hluav taws xob tseem ceeb, hauv kev ua haujlwm siab ntxiv, yog tias kev teeb tsa yog tsis tsim nyog, nws yuav ua rau tsis tsim nyog lub zog poob, thiab nyob rau hauv qee kis, nws yuav tsis muaj peev xwm tshem tawm kev sib haum xeeb.
Hauv cov ntsiab lus, qhov muaj kev txiav txim siab ua rau muaj kev sib tw thiab kev xaiv ua kom zoo dua qub Kev lim cov nyhuv .
