Lub Hwj Chim ntawm Pure Sine Inverters: Vim Li Cas Koj Thiaj Xav Tau Ib Qho Rau Koj Cov Kev Xav Tau Fais Fab
Yog tias koj paub txog lub ntiaj teb ntawm lub zog hnub ci thiab kev nyob tsis muaj hluav taws xob, tej zaum koj yuav tau ntsib lo lus "pure sine inverter" ib lossis ob zaug. Tab sis pure sine inverter yog dab tsi? Vim li cas nws thiaj tseem ceeb rau koj cov kev xav tau hluav taws xob? Hauv tsab blog no, peb yuav saib ze dua txog lub zog ntawm pure sine inverter thiab vim li cas koj yuav tsum xav txog ntxiv ib qho rau koj qhov kev teeb tsa.
Ua ntej, cia peb tham txog lub tshuab hluav taws xob ntshiab (pure sine inverter) yog dab tsi. Hauv cov lus yooj yim tshaj plaws, lub tshuab hluav taws xob ntshiab yog ib lub cuab yeej uas hloov lub zog hluav taws xob ncaj qha (DC) los ntawm lub roj teeb mus rau hauv lub zog hluav taws xob hloov pauv (AC) uas tuaj yeem siv los khiav cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Lub npe "pure sine" txhais tau tias lub inverter lub zog tso zis yog lub zog sine huv si, du, tib hom zog uas koj tau txais los ntawm koj lub tuam txhab hluav taws xob. Qhov no yog qhov sib txawv ntawm lub tshuab hluav taws xob sinusoidal uas tau hloov kho, uas tsim cov zog hluav taws xob hloov pauv thiab tsis sib xws.
Yog li ntawd, vim li cas lub waveform ntawm lub inverter thiaj tseem ceeb? Zoo, rau feem ntau cov khoom siv hluav taws xob thiab cov khoom siv yooj yim, lub inverter sine hloov kho yuav ua haujlwm zoo. Txawm li cas los xij, thaum nws los txog rau cov khoom siv hluav taws xob rhiab heev, xws li qee hom khoom siv suab, khoom siv kho mob, lossis cov cav hloov pauv ceev, lub inverter sine ntshiab yog qhov tseem ceeb. Cov khoom siv no xav tau lub zog huv si, ruaj khov kom ua haujlwm tau zoo, thiab cov inverters sine ntshiab muab qhov ntawd.
Tab sis nws tsis yog tsuas yog cov khoom siv hluav taws xob rhiab heev uas tuaj yeem tau txais txiaj ntsig los ntawm cov inverters ntshiab sine. Qhov tseeb, kev siv cov inverter ntshiab sine tuaj yeem pab txuas lub neej ntawm koj cov khoom siv thiab cov khoom siv hluav taws xob. Lub zog huv si uas muab los ntawm cov inverter ntshiab sine yuav tsis ua rau koj cov khoom siv puas tsuaj vim nws tshem tawm qhov kev pheej hmoo ntawm cov hluav taws xob nce siab thiab harmonics uas tuaj yeem tshwm sim nrog cov nthwv dej hloov kho sine.
Ntxiv rau qhov zoo dua rau koj cov khoom siv hluav taws xob, cov inverters ntshiab sine kuj feem ntau ua haujlwm tau zoo dua. Qhov no txhais tau tias koj yuav tau txais hluav taws xob ntau dua los ntawm koj lub roj teeb, uas yog qhov tseem ceeb tshwj xeeb yog tias koj vam khom lub zog hnub ci lossis cua. Hais txog lub zog rov ua dua tshiab, cov inverters ntshiab sine yog ib qho tseem ceeb ntawm txhua lub zog hluav taws xob tawm ntawm lub network. Yog tias koj nyob tawm ntawm lub grid, tej zaum koj twb paub zoo txog cov txiaj ntsig ntawm lub zog huv. Lub inverter ntshiab sine pab ua kom lub zog koj tsim tau huv thiab txhim khu kev qha ib yam li lub zog koj tau txais los ntawm lub grid.
Hauv kev xaus lus, txawm tias koj xav kom muaj zog rau cov khoom siv hluav taws xob rhiab heev, txuas lub neej ntawm koj cov khoom siv, lossis ua kom koj lub zog hluav taws xob tsis muaj zog tshaj plaws, cov inverters ntshiab sine yog ib qho tseem ceeb ntawm qhov kev sib tw. Yog tias koj xav tau tiag tiag txog koj cov kev xav tau hluav taws xob, nws tsim nyog xav txog kev ntxiv cov inverter ntshiab sine rau koj qhov kev teeb tsa. Muaj peev xwm xa hluav taws xob huv, sib xws thiab ua haujlwm tau zoo, cov inverters ntshiab sine yog qhov hloov pauv rau txhua tus neeg uas xav siv hluav taws xob.
