Kawm txogCov Inverters Ntshiab Sine: Kev daws teeb meem fais fab kawg
Lo lus "pure sine inverter" tab tom nrov zuj zus hauv lub zog rov ua dua tshiab thiab qhov chaw nyob tsis muaj hluav taws xob. Thaum ntau tus tib neeg thiab cov lag luam nrhiav kev daws teeb meem hluav taws xob ruaj khov, nws yog ib qho tseem ceeb kom nkag siab txog lub luag haujlwm thiab cov txiaj ntsig ntawm cov pure sine inverters. Tsab xov xwm no yuav saib ze dua ntawm cov pure sine inverters yog dab tsi, lawv ua haujlwm li cas, thiab vim li cas lawv thiaj li xaiv tau zoo rau ntau daim ntawv thov.
Lub inverter ntshiab sine yog dab tsi?
Lub inverter ntshiab sine yog ib lub cuab yeej uas hloov cov hluav taws xob ncaj qha (DC) mus rau hauv cov hluav taws xob hloov pauv (AC) nrog cov qauv tso zis du uas zoo ib yam li cov hluav taws xob uas cov tuam txhab hluav taws xob muab. Lub inverter no yog tsim los muab lub zog huv si, ruaj khov, zoo tagnrho rau cov khoom siv hluav taws xob rhiab heev thiab cov khoom siv hauv tsev.
Lub inverter sine ntshiab ua haujlwm li cas?
Muaj ntau yam tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm lub inverter ntshiab sine. Ua ntej, lub inverter siv lub zog DC los ntawm lub roj teeb lossis lub hnub ci vaj huam sib luag. Tom qab ntawd nws siv ntau lub voj voog hluav taws xob los hloov lub zog DC mus rau hauv lub zog AC. Cov duab tso zis tawm yog tsim los ntawm cov txheej txheem hu ua pulse width modulation (PWM), uas tsim cov duab pulses uas tau du kom tsim tau cov nthwv dej ntshiab sine.
Cov txheej txheem no ua kom ntseeg tau tias qhov hluav taws xob tso zis thiab zaus tseem sib xws, ua rau nws haum rau ntau yam kev siv. Tsis zoo li cov inverters hloov kho sine wave, uas tsim cov duab sawtooth waveform, cov inverters ntshiab sine wave muab cov zis huv dua uas yuav tsis ua rau muaj kev cuam tshuam nrog cov khoom siv hluav taws xob rhiab heev.
Qhov zoo ntawm cov inverter ntshiab sine
1. Kev Sib Piv Nrog Cov Khoom Siv Hluav Taws Xob rhiab heev: Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov inverters ntshiab sine yog lub peev xwm los muab hluav taws xob rau cov khoom siv rhiab heev xws li khoos phis tawj, cov khoom siv kho mob, thiab cov kab ke suab-pom tsis muaj kev cuam tshuam lossis kev puas tsuaj. Qhov no ua rau lawv zoo tagnrho rau cov tsev nyob, RV, thiab cov kab ke tawm-grid.
2. Kev Txhim Kho Kev Ua Haujlwm: Cov inverters sine wave feem ntau ua haujlwm tau zoo dua li cov inverters retrofit. Lawv muaj peev xwm tso zis hluav taws xob tau zoo dua, txo qhov poob hluav taws xob thaum lub sijhawm hloov pauv. Qhov kev ua haujlwm tau zoo no txhais tau tias lub roj teeb siv tau ntev dua thiab cov nqi hluav taws xob qis dua.
3. Txo Suab Nrov: Lub waveform tso zis du ntawm lub inverter sine wave ntshiab txo qhov suab nrov hluav taws xob, uas yog qhov teeb meem tseem ceeb nrog cov inverter sine wave hloov kho. Qhov kev txo suab nrov no tshwj xeeb tshaj yog rau cov khoom siv suab thiab lwm yam khoom siv rhiab heev uas xav tau lub zog huv.
4. Ua kom cov khoom siv hluav taws xob siv tau ntev dua: Cov khoom siv hluav taws xob uas siv cov inverters ntshiab feem ntau muaj lub neej ua haujlwm ntev dua. Kev muab hluav taws xob ruaj khov tuaj yeem txo qhov hnav ntawm cov cav thiab lwm yam khoom, yog li txo cov kev kho thiab hloov pauv.
5. Kev Siv Tau Ntau Yam: Cov inverters ntshiab muaj ntau yam thiab haum rau ntau yam kev siv los ntawm cov chaw nyob mus rau cov chaw ua lag luam. Lawv kuj tsim nyog rau cov tshuab hluav taws xob rov ua dua tshiab xws li lub hnub ci thiab cua, ua rau lawv yog ib feem tseem ceeb ntawm kev daws teeb meem hluav taws xob ruaj khov.
Hauv luv luv
Hauv kev xaus lus, cov inverters ntshiab sine wave yog ib feem tseem ceeb ntawm lub ntiaj teb hloov pauv zog, thiab lawv cov txiaj ntsig ntau yam ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev muab hluav taws xob rau cov khoom siv hluav taws xob rhiab heev thiab cov khoom siv hauv tsev. Lawv muab lub zog huv, ruaj khov, ua kom muaj kev sib raug zoo nrog ntau yam khoom siv, thaum lawv cov yam ntxwv ua haujlwm siab thiab suab nrov qis kuj pab txhim kho kev paub ntawm tus neeg siv tag nrho. Raws li qhov kev thov rau cov kev daws teeb meem zog rov ua dua tshiab txuas ntxiv mus, kev nkag siab txog qhov tseem ceeb ntawm cov inverters ntshiab sine wave yog qhov tseem ceeb rau txhua tus neeg uas tab tom nrhiav kev siv lub zog huv kom zoo. Txawm hais tias nws yog rau kev siv hauv tsev, RV kev taug txuj kev nyuaj, lossis kev nyob tawm ntawm lub network, kev nqis peev rau hauv lub inverter ntshiab sine wave tuaj yeem ua rau muaj kev daws teeb meem zog txhim khu kev qha thiab ua haujlwm tau zoo dua.
