Ntau thiab ntau cov neeg muas zaub mob siab txog cov harmonics, ces dab tsi yog harmonic, dab tsi yog harmonic kev puas tsuaj, tam sim no cia kuv muab rau koj ib co kev taw qhia.
Nyob rau hauv ib lo lus, nyob rau hauv hluav taws xob fais fab system, harmonic ntawm tam sim no los yog voltage waveform yog ib tug sinusoidal nthwv dej uas nws zaus yog ib tug integer ntau ntawm lub hauv paus zaus.
Hauv Tebchaws Meskas, qhov tseem ceeb zaus yog 60Hz, tab sis nyob rau hauv European thiab Esxias kev lag luam, nws yuav yog 50Hz.Hauv 60Hz system tuaj yeem suav nrog 2nd-order harmonics ntawm 120Hz, 3rd-order ntawm 180Hz, 5th-order ntawm 300Hz, thiab lwm yam. Hauv 50Hz system tuaj yeem suav nrog 2nd-order harmonics ntawm 100Hz, 3rd-order ntawm 150Hz, 5th-order ntawm 250Hz, thiab lwm yam. Ua ke, lawv xa ib qho kev cuam tshuam tag nrho rau lub hauv paus zaus waveform .
Koj puas muaj lus nug loj txog yuav ua li cas harmonics raug tsim?
Nonlinear loads tsim kev sib haum xeeb nrog kev hloov pauv sai, xws li kev hloov pauv zaus, hloov pauv ceev, kev hloov pauv, servo drives, LED teeb pom kev zoo, lossis cov tshuab hluav taws xob zoo li cov khoom siv vuam.Nyob rau hauv tus txheej txheem ntawm rectifying thiab inverting, vim lub siab hloov zaus, siab harmonics yuav raug tsim.
Puas yog harmonics muaj kev puas tsuaj rau hluav taws xob hluav taws xob?Yog, nws yuav tsum.
Raws li ntau thiab ntau lub zog hluav taws xob hluav taws xob hluav taws xob sib xyaw ua ke rau hauv peb cov hluav taws xob faib hluav taws xob, cov tshuab hluav taws xob hluav taws xob yuav pom ntau yam kev puas tsuaj.
Harmonics yuav tsum muaj qhov tshwm sim loj heev.Yog hais tias harmonics puas ib tug rhiab ntaus ntawv, tej zaum yuav ua rau zus tau tej cov tsis ua hauj lwm.Cov harmonics yuav ua rau tag nrho cov fais fab mov poob.Vim yog lub zog reactive, theem tsis sib npaug, qhov hloov pauv ntawm qhov hluav taws xob (flicker), thiab qhov cuam tshuam rau kev sib raug zoo tam sim no, daim phiaj hluav taws xob yuav tsum muaj kev cuam tshuam lossis kev txaus ntshai overloading.
Yog hais tias peb yuav daws tau cov harmonics?Yog lawm, Noker Electric yuav pab koj ua qhov no.
Xi'an Noker Electric yog cov kws tshaj lij fais fab khoom tsim khoom, muabactive zog lim, reactive zog compensator, hybrid compensatorthiab lwm yam kev daws teeb meem.Yog tias koj muaj teeb meem hluav taws xob zoo, thov koj xav tiv tauj peb.
