Photovoltaic tawm-kab sib tw inverter

Khoom Taw Qhia
Lub PV tawm-kab sib chaws Inverter yog lub zog hloov pauv hloov cov tswv yim rau hauv Inverter Choj Spij Sinusoidal Tshuab.
Zoo li cov kab sib txuas nrog Inverters, PV OffID Offerers yuav tsum muaj kev ua haujlwm siab, siab ntseeg tau, thiab ntau yam ntawm DC cov tswv yim voltage; Hauv nruab nrab- thiab loj-muaj peev xwm PV fais fab, cov zis ntawm inverter yuav tsum yog lub wave sinusoidal nrog cov distortion tsawg.

Kev ua tau zoo thiab nta
1. 16-ntsis microhontroller lossis 32-ntsis DSP microprocessor siv rau kev tswj hwm.
2.Pwsm tswj hom, zoo siab txhim kho kev ua tau zoo.
3.Sadopt digital lossis LCD los tso tawm ntau yam kev ua haujlwm tsis zoo, thiab tuaj yeem teeb tsa qhov cuam tshuam.
4. Square yoj, hloov kho yoj, sine yoj tawm. Sine yoj tawm cov zis, waveform distortion tus nqi tsawg dua 5%.
5. Kev ua haujlwm siab ntsuas qhov tseeb, hauv qab cov paj laum, cov zis tawm yog feem ntau tsawg dua ntxiv lossis rho tawm 3%.
6. Quav pib qeeb ua haujlwm kom tsis txhob cuam tshuam cov roj teeb thiab thauj khoom.
7. Cov siab dua hloov hluav taws xob kev sib cais, qhov loj me thiab lub teeb hnyav.
8. Nruab nrog cov qauv RS232 / 485 Kev sib txuas lus interface, yooj yim rau kev tswj kev sib txuas lus tej thaj chaw deb.
9. Yuav siv tau rau ib puag ncig ib puag ncig 5500 metres saum hiav txwv hiav txwv.
10, nrog cov lus tawm tswv yim rov qab kev tiv thaiv, cov tswv yim uncervoltage tiv thaiv, tawm kev tiv thaiv luv luv circuit Court, overheat tiv thaiv thiab lwm yam kev tiv thaiv.

Cov ntsiab lus tseem ceeb ntawm kev tawm tsam
Thaum xaiv cov phiaj xwm tawm hauv cov pob txha caj qaum, dua li them nyiaj rau cov khoom siv hluav taws xob uas muaj zog, muaj zog ntau dua, hloov dua siab tshiab, hloov lub sijhawm, Lwm yam. Kev xaiv ntawm cov teeb meem no tau muaj kev cuam tshuam zoo rau lub peev xwm kev thov hluav taws xob.
1) qhov system voltage:
Nws yog qhov hluav taws xob ntawm cov roj teeb pob. Lub tswv yim voltage ntawm cov tawm-kab sib txuas thiab cov zis hluav taws xob ntawm cov maub los ntawm cov maub los ntawm cov maub los yog tib yam, yog li tsim qauv thiab xaiv saib xyuas kom zoo ib yam nrog tus maub los.
2) Tso zis zog:
OFF-GRID inverter tso zis hluav taws xob muaj zog, ib qho yog lub zog hluav taws xob, xws li 500va tawm-kab sib tw inverter , lub hwj chim siv yog 0.8, qhov tseeb tso zis nquag siv zog yog 400W, tuaj yeem tsav tsheb 400W cuam tshuam, xws li hluav taws xob teeb, thiab lwm yam .; Qhov thib ob yog lub zog nquag qhia, chav nyob yog w, xws li 5000w tawm-kab sib chaws inverter, qhov tseeb tso zis nquag siv zog yog 5000W.
3) Lub zog ncov:
Hauv PV Off-Grid System, cov roj teeb, roj teeb, xws li cov tshuab hluav taws xob, cov tshuab hluav taws xob, twj, thiab lwm yam., Lub cev muaj zog hauv, tus Pib lub zog yog 3-5 zaug lub ntsuas hluav taws xob, yog li cov phiaj xwm tawm hauv Inverter muaj cov cai tshwj xeeb rau kev tshaj lij. Lub zog ncov yog qhov dhau lub peev xwm ntawm cov kab sib tw.
Lub Inverter muab lub zog pib rau lub nra, ib nrab ntawm lub zog lossis siv hluav taws xob sib xyaw sab hauv cov inverter - capactritors thiab inductors. Peev hluav taws xob thiab inductors yog ob lub zog ntim, tab sis qhov txawv yog lub peev xwm hluav taws xob hauv daim ntawv hluav taws xob, thiab cov khoom siv hluav taws xob loj dua uas nws tuaj yeem khaws cia. Inductors, ntawm qhov tod tes, khaws lub zog hauv daim ntawv ntawm cov sib nqus. Qhov ntau dua cov sib nqus pertability ntawm cov inductor tub ntxhais, ntau dua qhov tsis sib xws, thiab lub zog ntau ntxiv uas tuaj yeem khaws cia.
4) Kev hloov dua siab tshiab:
Kev hloov kho cov kab ke tawm-sib hloov pauv tau zoo nrog ob txoj kev ua tau zoo, yog li qhov ua tau zoo dua, kom muaj kev ua tau zoo dua, yog li qhov qis dua qhov sib txuas hauv cov kab sib chaws, feem ntau Nruab nrab ntawm 80-90%, ntau dua lub zog ntawm inverter tshuab kev ua hauj lwm tau ntau dua, qhov siab dua lub system voltage kuj tseem siab dua. Thib ob, kev ua tau zoo ntawm roj teeb them thiab kev tso tawm, qhov no yog cov roj teeb synchronization, thaum lub hwj chim fais fab tuaj yeem hloov kho cov roj teeb hloov dua tshiab.
5) hloov sijhawm:
Cov kab ke off-grid nrog lub nra, muaj ntau hom phiaj xwm siv hluav taws xob, thaum lub sijhawm hloov hluav taws xob, thaum lub sijhawm hloov hluav taws xob, lub sijhawm hloov hluav taws xob, lub sijhawm tsis pub dhau 10 milliseconds, Cov khoos phis tawj desktop yuav tsis kaw, teeb pom kev zoo yuav tsis flicker. Ib co off-daim phiaj inverters siv Repay hloov, lub sijhawm tej zaum yuav muaj ntau tshaj 20 milliseconds, thiab lub cim lub computer kaw los yog rov pib dua.
