Yuav tsim thiab xam Solar Street Light System li cas?
Jul 07, 2021
Raws li lub zog tshiab txoj kev teeb,hnub ci txoj kev teeb tau siv dav thoob plaws ntiaj teb. Txawm li cas los xij, muaj ntau yam teeb pom kev hauv kev lag luam nrog cov wattages sib txawv. Thaum cov neeg siv khoom siv lub hnub ci teeb pom kev zoo, lawv feem ntau muaj cov lus nug: Kuv yuav tsum muab pes tsawg wattage solar panels los xyuas kom meej lub sijhawm ua haujlwm thiab qhov ci ntawm txoj kev teeb? Kab lus no yuav qhia koj cov lus teb.
Lus Nug: Yuav ua li cas tsim thiab xam lub Hnub Ci Txoj Kev Teeb?
Qhov teeb meem no yog qhov tseem ceeb ntawm qhov sib npaug ntawm kev siv hluav taws xob ntawm LED teeb thiab lub zog tsim hluav taws xob ntawm hnub ci vaj huam sib luag. Yog li ntawd, peb yuav tsum xub kawm los xam lub zog noj ntawm LED teeb.
Noj 30W teeb ua haujlwm rau 6 teev ua piv txwv, peb xav tias nws qhov ci ci yog 100 feem pua ntawm thawj peb teev thiab 50 feem pua rau peb teev tom ntej. Tom qab ntawd, nws siv zog yog30 * (3 * 100 feem pua ntxiv rau 3 * 50 feem pua) =135WH
Yog tias koj lub teeb yog 100W, thiab nws qhov ci ci yog 100 feem pua rau 12 teev, ces nws lub zog siv yog100 * 12 * 100 feem pua =1.2KWH
Thiab li ntawd. (Nws yuav tsum tau muab sau tseg tias yog lub hnub ci vaj huam sib luag muab lub zog rau ob lub teeb LED tib lub sijhawm, cov txiaj ntsig ntawm kev siv hluav taws xob ntawm ob lub teeb LED yuav tsum tau muab xam.)
Los ntawm kev suav ntawm kev siv hluav taws xob, nws tsis yooj yim rau kev pom tias: thaum koj xaiv lub hnub ci txoj kev teeb, koj yuav tsum xub nkag siab txog koj cov teeb pom kev zoo. Hauv lwm lo lus, dab tsi wattage LED teeb koj xav yuav? Koj xav tau ntev npaum li cas rau lub teeb txhua hnub? Puas yog lub teeb ci LED yuav tsum tswj 100 feem pua qhov ci tsis tu ncua thaum lub sijhawm teeb pom kev zoo, lossis qhov ci ntsa iab txawv ntawm lub sijhawm sib txawv?
Tom qab txheeb xyuas cov lus nug yooj yim, cia peb saib cov lus nug tseem ceeb: Kuv yuav tsum muaj hwj chim npaum li cas rau kuv txoj kev teeb nrog hnub ci vaj huam sib luag? (Ua rau saum toj no 30W LED teeb ua piv txwv dua. Peb nyuam qhuav suav tias nws lub zog siv yog 135WH.)
Tam sim no peb pib xam:
1 Kauj ruam 1: xam qhov tam sim no.
Peb lub roj teeb feem ntau yog 12V, thaum lub zog ntawm LED yog 30W (uas yog, lub zog siv yog 135WH), cov khoom siv tam sim no yog:135WH/12V=11.25Ah
2 Kauj ruam 2: Xam lub roj teeb muaj peev xwm yuav tsum tau.
Txuas ntxiv mus coj 30W LED teeb ua haujlwm rau 6 teev ua piv txwv, thaum tus neeg siv khoom xav tau los xyuas kom meej tias nws tuaj yeem teeb pom kev rau 3 hnub los nag, thiab ntxiv rau qhov kev thov teeb pom kev zoo ntawm yav dhau los hmo ntuj, lub roj teeb muaj peev xwm yuav tsum ncav cuag 4 hnub. .
Lub roj teeb muaj peev xwm ntawm lub sijhawm no yog:11.25Ah*4 hnub=45Ah
Txhawm rau tiv thaiv lub roj teeb los ntawm kev them nyiaj ntau dhau thiab tshaj tawm, lub peev xwm ntawm lub roj teeb yuav tsum yog 20 feem pua siab dua qhov xav tau tiag tiag. Hauv lwm lo lus, thaum peb qhov kev thov tiag tiag rau lub peev xwm yog 45Ah, peb yuav tsum tau nruab ib lub roj teeb nrog lub peev xwm ntawm 45Ah.45*(1 plus 20%)=54Ah.
3 Kauj Ruam 3: Xam lub zog xav tau ntawm lub hnub ci vaj huam sib luag.
Ua ntej xam lub hwj chim, peb yuav tsum to taub 3 lub tswv yim.
Kev tsim hluav taws xob ntawm cov hnub ci vaj huam sib luag. Nws yuav tsum tau nce li ntawm 30 feem pua ntawm kev siv hluav taws xob.
Qhov nruab nrab siv lub sijhawm teeb pom kev zoo. Feem ntau hais lus, lub sijhawm teeb pom kev zoo yog 4-5 teev, thiab cov xwm txheej tshwj xeeb txawv hauv ntau qhov chaw hauv ntiaj teb.
Lub zog tsim efficiency. Lub zog tsim hluav taws xob ntawm cov hnub ci vaj huam sib luag feem ntau yog 70 feem pua -80 feem pua . Qhov kev ua tau zoo no muaj feem xyuam rau cov khoom siv thiab qhov zoo ntawm lub hnub ci vaj huam sib luag. Peb xam raws li 75 feem pua.
Cov qauv yooj yim yog:Lub zog tsim hluav taws xob ntawm lub hnub ci vaj huam sib luag=lub zog * nruab nrab lub sijhawm teeb pom kev zoo * lub zog tsim hluav taws xob.
Hauv lwm lo lus,hwj chim=yuav tsum tau siv fais fab / (lub sij hawm teeb pom kev zoo * lub zog tsim efficiency)
Hloov cov lej:hwj chim=(135WH * 130%)/(4.5H * 75%)=52W
Txhawm rau ua kom tiav, koj xav tau lub hnub ci vaj huam sib luag nrog lub zog ntau dua 52W, thiab cov roj teeb sib txuas yuav tsum muaj ntau dua 54Ah.
