Hais txog Cheebtsam
24VLED: Xaiv lub teeb pom kev zoo LED, uas muaj lub neej ua haujlwm ntev, teeb pom kev zoo, thiab tus nqi tsim nyog. Nws tuaj yeem ua tiav kev tswj hwm hluav taws xob thaum lub sijhawm tsis tshua muaj neeg taug kev thaum hmo ntuj, uas yog qhov tsim nyog rau kev txuag hluav taws xob, yog li txo qis kev teeb tsa ntawm cov roj teeb, thiab txuag nqi. Txog 80-105lm ib watt, nrog lub teeb attenuation tsawg dua lossis sib npaug li 5 feem pua ntawm ib xyoos;
12V roj teeb (txoj hlua 24V): Lead acid txij nkawm dawb roj teeb raug xaiv, nrog tus nqi nruab nrab thiab kev ua haujlwm ruaj khov. Nws yog qhov kev xaiv zoo tshaj plaws rau hnub ci txoj kev teeb;
12V roj teeb lub rooj tsavxwm (txoj hlua 24V): kev hloov pauv tus nqi siab dua 15 feem pua ntawm ib qho khoom siv lead ua zoo;
24V maub los: MCT them hom, nrog lub zog tswj kev ua haujlwm (ntxiv cov ntaub ntawv txuas nrog);
6M teeb ncej (tseem muaj qhov zoo nkauj zoo nkauj, ua haujlwm ntev, thiab tus nqi qis)
40W Example 1
LED teeb, ib lub voj voog, 40W, 24V system;
2. Lub teeb pom kev zoo hauv zos txhua hnub yog xam raws li 4h;
3. Lub sijhawm tso tawm txhua hnub yog 10 teev (siv 7 teev tsaus ntuj txog 5 teev sawv ntxov ua piv txwv)
4. Ua tau raws li qhov yuav tsum tau muaj 5 hnub los nag (ntxiv rau 6 hnub ntawm kev siv hluav taws xob rau hmo ua ntej hnub los nag).
Tam sim no =40W ÷ 24V=1.67 A
Xam roj teeb =1.67A × 10h × (5 ntxiv rau 1) hnub
= 1.67A × 60h=100 AH
Khaws 20 feem pua muaj peev xwm rau roj teeb them thiab tawm; Qhov tseeb tam sim no ntawm txoj kev teeb yog siab dua 2A (ntxiv rau 20 feem pua poob, suav nrog qhov chaw tam sim no, kab poob, thiab lwm yam)
Qhov xav tau roj teeb tiag tiag =100 AH ntxiv rau 20 feem pua tiav peev xwm, ntxiv rau 20 feem pua poob
100AH ÷ 80% × 120%=150AH
