Countermeasures rau Thaum siab dua Harmonics nyob rau hauv daim phiaj fais fab tuag tshaj qhov tso cai txwv

Nrog rau kev nce qib ntawm industrialization, kev ua haujlwm thiab kev thauj khoom ntawm lub tshuab hluav taws xob tau dhau los ua qhov nyuaj. Tshwj xeeb tshaj yog, kev siv dav dav ntawm cov khoom tsis yog - linear loads hauv ntau lub tuam txhab kev lag luam niaj hnub no tau ua rau muaj kev sib raug zoo siab dua hauv kab hluav taws xob. Kev sib raug zoo siab dua yog qhov teeb meem ntawm lub zog zoo hauv cov tshuab hluav taws xob. Yog li, dab tsi yuav tsum tau ua thaum muaj kev sib haum xeeb siab dua hauv daim phiaj hluav taws xob tshaj li qhov tso cai?

I. Dab tsi yog Harmonics siab dua?
Kev sib raug zoo siab dua yog hais txog electromagnetic waveforms hauv lub zog hluav taws xob uas qhov zaus ntawm cov teeb liab tam sim no lossis qhov hluav taws xob yog qhov sib npaug ntawm qhov ntau zaus (piv txwv li, thib 2 harmonic, 3rd harmonic, thiab lwm yam). Lawv feem ntau tshwm sim los ntawm qhov tsis yog - cov khoom tawm xws li cov khoom siv hluav taws xob, hluav taws xob arc rauv, thiab cov khoom siv hluav taws xob.

II. Kev cuam tshuam ntawm kev sib raug zoo siab dua li kev tso cai

1. Cov khoom siv cua sov thiab kev puas tsuaj
Qhov cuam tshuam ntawm kev sib raug zoo siab dua ntawm cov khoom siv hluav taws xob yog qhov tseem ceeb. Lawv tuaj yeem ua rau overheating hauv transformers, motors, lub zog hluav taws xob cov khoom siv hluav taws xob, thiab lwm yam khoom siv, txo lawv lub neej kev pab cuam thiab txawm tias ua rau cov cuab yeej tsis ua haujlwm.

2. Ntau zog poob
Kev sib raug zoo siab dua tuaj yeem ua rau lub zog poob hauv lub zog. Harmonic Cheebtsam cuam tshuam rau lub waveform ntawm tam sim no, yog li txo qhov ua tau zoo ntawm cov khoom siv hluav taws xob. Tshwj xeeb tshaj yog thaum lub sij hawm ntev - kis tau tus mob nyob deb, harmonics tsis tsuas yog ua rau kom tsis txhob kis tau tus mob, tab sis kuj yuav ua rau muaj teeb meem zoo zog, cuam tshuam rau tag nrho cov kev siv zog efficiency.

3. Cov khoom cuam tshuam thiab kev sib txuas lus teeb meem
Kev sib raug zoo siab dua tuaj yeem cuam tshuam nrog lwm yam khoom siv rhiab heev. Piv txwv li, kev sib haum xeeb tuaj yeem ua rau muaj kev tsis sib haum xeeb hauv kev tswj hwm, cuam tshuam kev lag luam ib txwm muaj ntawm cov tshuab automation, thiab tseem ua rau muaj teeb meem hauv kev sib txuas lus.

III. Yuav ua li cas hais txog kev sib raug zoo siab tshaj qhov tso cai txwv nyob rau hauv daim phiaj fais fab?

1. Nruab Active Power Filters (APF)
IbActive Fais Fab Filter (APF)yog ib lub cuab yeej tshwj xeeb tsim los rau kev sib haum xeeb. Nws tuaj yeem txheeb xyuas cov khoom sib haum xeeb hauv daim phiaj hluav taws xob hauv lub sijhawm tiag tiag thiab tiv thaiv cov kev sib haum xeeb los ntawm kev txhaj tshuaj tiv thaiv tam sim no. APFs muab cov lus teb ceev ceev thiab muaj peev xwm tiv thaiv kev sib haum xeeb, ua rau lawv tsim nyog rau cov tshuab hluav taws xob uas muaj teeb meem hnyav dua.

2. Configure Filter Reactors
Lim reactors, tseem hu ua harmonic filters, ua hauj lwm nrog cov khoom xws li capacitors thiab induction coils los tsim ib tug harmonic filtering network, zoo tshem tawm los yog suppressing tej zaus harmonics nyob rau hauv lub hwj chim system. Feem ntau, lim reactors tau teeb tsa ua ke nrog cov khoom siv hluav taws xob, uas tuaj yeem txo qhov cuam tshuam ntawm kev sib raug zoo siab dua thiab tswj xyuas lub zog zoo ntawm daim phiaj.
