Heerarka Tijaabada Korantada-sare & Sababaha loo yaqaan Luminaires LED
1. Nalalka LED-ka waxaa lagu tijaabiyaa sababaha soo socda:
1) Marka nalka la shido, korantada la helay waxay yeelan doontaa danab garaaca wadnaha degdega ah, waqtigan, waxaa jiri doona jiil weyn oo hadda jira. Laakin haddii daadadku aad u badan yahay, waxay dhaawac u keeni kartaa jidhka bini'aadamka.
2) Guud ahaan, ujeedada codsashada tamarta sare waa in laga hortago waxyeellada alaabta. Dhanka kale, sidoo kale waa in la tijaabiyo waxqabadka dahaarka ee badeecada iyo in la xaqiijiyo in waxqabadkani uu yahay mid wax ku ool ah. Haddii farqiga golaha guryeynta ee luminaire laftiisa uu yar yahay oo ay jirto ismaandhaaf gaar ah oo ka mid ah dusha shirka kasta, waxay awood u yeelan doontaa in ay u adkeyso qiyaasta sare ee 2500V ee lagu dabaqo qaybaha la dallacay iyo balaastigga guryaha. Intaa waxaa dheer, waa in la hubiyaa in kuwan sagxadaha iyo walxaha caaga ah aysan dhalaalin oo aan isbeddelin hawlgalka caadiga ah, si ay u saameeyaan waxqabadka daboolka ee nalka laftiisa.
2. Hababka cabbiraadda dheeriga ah:
1) Ku xidhida furaha mishiinka tamarta sare ee "220V" jaakadda, ka dibna mishiinka sare ee tamarta korontada, shid dhammaan furayaasha.
2) Qalabka korantada ee mashiinka-sare ee mashiinka "voltage" "waqtiga" faylka loo baahan yahay ee jirka laambadda lagu ogaanayo ee booska loo baahan yahay, bilow imtixaan kasta iyadoo loo eegayo aragtida cusub "voltage" "Leakage current" "waqtiga imtixaanka" iyo shuruudaha imtixaanka.
3) Ka dibna isticmaal mishiinka baadhista mishiinka sare iyo xidhiidhka dhulka (GND), haddii uu jiro qaylo-dhaan, mishiinkan-voltage-ka sare waa caadi, waa la isticmaali karaa.
4) Furaha jidhka laambadda xidhiidh la xidhiidha mishiinka dhulka hoostiisa-sare ee (GND) birta ama godka, ka dibna isticmaal qaybta birta ah ee usha baadhista tamarta-sare si aad u gujiso birta jidhka laambadda ama qayb kasta oo ka mid ah marinka, haddii Mashiinka korantada-sare ma qeylin, taasoo muujineysa in laambada tijaabada korontadu ay dhaaftay.
