Yuav ua li cas tsis ua hauj lwm zaus yuav ua rau lwm yam khoom siv? yuav tiv thaiv li cas
Kev hloov hluav taws xob ntau zaus yog siv rau kev sim thiab kev debugging ntawm cov khoom siv hluav taws xob txawv teb chaws thiab xa tawm hluav taws xob thiab cov khoom siv hluav taws xob ntawm cov cuab yeej siv hluav taws xob, dav siv hauv kev tsim khoom siv hauv tsev, kev tsim hluav taws xob, IT kev lag luam, khoom siv computer, thiab lwm yam. Txawm li cas los xij, kev teeb tsa thiab kev siv cov khoom sib txawv. zaus fais fab mov yuav cuam tshuam rau lwm yam khoom siv hauv lub cev, thiab qee zaum txawm ua rau lwm yam khoom siv ua haujlwm tsis zoo. Dab tsi yog qhov tshwj xeeb tshwm sim? Yuav tsum tau ceev faj dab tsi?
Dab tsi ntawm qhov tsis ua haujlwm yuav hloov pauv lub zog hluav taws xob ua rau lwm yam khoom siv? yuav tiv thaiv li cas
Ntawm qhov teeb meem ntawm high-order harmonics nyob rau hauv lub hwj chim mov. Txij li yuav luag txhua qhov sib txawv ntawm cov khoom siv hluav taws xob siv hluav taws xob siv PWM (Pulse Width Modulation) tswj hom, thaum lub zog sib txawv ntawm cov khoom siv hluav taws xob ua haujlwm thiab cuam tshuam qhov hluav taws xob waveform, hom kev hloov kho no yuav tsim kom muaj kev sib haum xeeb siab dua ntawm lub zog hluav taws xob, uas ua rau muaj qhov hloov pauv ntawm Waveform. distortion, ua rau muaj kev phiv.
Peb pom zoo kom koj siv txoj hauv qab no los tiv thaiv qhov tshwm sim: Siv lub tshuab hluav taws xob tshwj xeeb los txhawb lub zog ntawm cov khoom siv hluav taws xob sib txawv thiab cais tawm ntawm lwm lub tshuab hluav taws xob. Nruab ib lub lim inductor los yog ntau lub rectifier choj circuits nyob rau sab input ntawm qhov sib txawv zaus fais fab mov kom txo tau cov kev txiav txim siab sib haum xeeb. Rau cov theem capacitors, high-order harmonic tam sim no yuav ua rau kom lub capacitor tam sim no thiab ua kom muaj cua sov ntau, lub choke coil yuav tsum tau txuas nrog rau hauv cov dej ntws ntawm cov capacitor kom txo tau cov khoom sib haum xeeb, thiab qhov inductance ntawm choke coil yuav tsum raug soj ntsuam kom raug thiab xam kom tsis txhob tsim inductance thiab capacitive oscillations.
Lus nug txog lub cev muaj zog overheating thiab kev khiav hauj lwm ntau yam. Yog tias qee lub tuam txhab retrofit cov motors uas twb muaj lawm nrog zaus hloov dua siab tshiab thiab ceev tswj, lub peev xwm txias ntawm tus kheej-txias motors yuav raug txo thaum lub sijhawm ua haujlwm qis, ua rau lub cev muaj zog. Tsis tas li ntawd, qhov kev txiav txim siab sib haum xeeb uas muaj nyob rau hauv cov zis waveform ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob yuav ua rau cov hlau poob thiab tooj liab poob ntawm lub cev muaj zog. Yog li ntawd, tom qab paub meej tias lub xeev ntawm tus nqi thiab kev ua haujlwm ntawm lub cev muaj zog, nws raug nquahu kom ua raws li cov kev ntsuas hauv qab no: qib kev qhia tshwj xeeb ntawm lub cev muaj zog, siv lub cev muaj zog rau kev hloov pauv zaus, txwv kev ua haujlwm ntau thiab tsis txhob muaj qhov chaw qis. .
Hais txog cov nyhuv ntawm qhov siab tshaj voltages generated los ntawm high-frequency switching ntawm lub cev muaj zog rwb thaiv tsev. Cov zis hluav taws xob ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob sib txawv muaj cov hluav taws xob ntau dhau, thiab cov kev txiav txim siab ntawm cov pulse voltages no yuav txo cov rwb thaiv tsev ntawm lub cev muaj zog winding, tshwj xeeb tshaj yog nyob rau hauv qhov sib txawv zaus PWM tswj fais fab mov. Cov kev ntsuas hauv qab no tuaj yeem ua tau: Txo qhov txuas txuas ntawm qhov sib txawv ntawm lub zog hluav taws xob thiab lub cev muaj zog. Tshem tawm qhov hluav taws xob surge nrog thaiv diodes los tswj cov zis hluav taws xob ntawm cov khoom siv hluav taws xob sib txawv, thiab rau cov khoom siv hluav taws xob sib txawv, sim ntxiv lim rau ntawm lub cev muaj zog input ntaus ntawv.
