High-voltage Test Standards & Yog vim li cas rau LED Luminaires
1. LED luminaires raug sim rau cov laj thawj hauv qab no:
1) Thaum lub teeb qhib, qhov tau txais qhov hluav taws xob yuav muaj qhov hluav taws xob tam sim no, lub sijhawm no, yuav muaj ntau tiam tam sim no. Tab sis yog tias tam sim no xau ntau dhau, nws yuav ua rau muaj kev phom sij rau tib neeg lub cev.
2) Feem ntau, lub hom phiaj ntawm kev siv high voltage yog los tiv thaiv kev puas tsuaj rau cov khoom. Ntawm qhov tod tes, nws tseem yog los ntsuas qhov kev ua haujlwm rwb thaiv tsev ntawm cov khoom thiab xyuas seb qhov kev rwb thaiv tsev no puas zoo. Yog hais tias lub vaj huam sib luag sib txawv ntawm lub luminaire nws tus kheej me me thiab muaj qee qhov tsis zoo ntawm txhua qhov sib dhos, nws yuav muaj peev xwm tiv taus 2500V siab voltage thov rau ntawm qhov chaw them nyiaj thiab vaj tse yas. Tsis tas li ntawd, nws yuav tsum tau xyuas kom meej tias cov mating nto thiab cov ntaub ntawv yas tsis yaj thiab deform nyob rau hauv ib txwm ua hauj lwm, thiaj li hais tias nws cuam tshuam rau lub rwb thaiv tsev kev ua tau zoo ntawm lub teeb nws tus kheej.
2. Kev ntsuas ntxiv:
1) Txuas lub ntsaws ntawm lub tshuab high-voltage mus rau "220V" jack, thiab tom qab ntawd lub tshuab hluav taws xob high-voltage mus rau hauv lub hwj huam mov, tig rau txhua lub keyboards.
2) Lub tshuab hluav taws xob high-voltage cov khoom siv hluav taws xob "voltage" "time" cov ntaub ntawv mus rau qhov yuav tsum tau pom lub teeb lub cev ntawm qhov xav tau ntawm txoj haujlwm, pib txhua qhov kev sim raws li qhov kev pom tshiab "voltage" "kawg tam sim no" "lub sijhawm sim" thiab cov kev xeem yuav tsum tau ua.
3) Thiab tom qab ntawd siv lub tshuab hluav taws xob high-voltage sojntsuam pas nrig thiab hauv av kawg (GND) kev sib cuag, yog tias muaj lub tswb nrov, lub tshuab hluav taws xob siab no yog qhov qub, tuaj yeem siv tau.
4) Lub teeb lub cev ntsaws hu rau high-voltage tshuab grounding kawg (GND) hlau phaj los yog lub qhov (socket), thiab ces siv cov hlau ib feem ntawm high-voltage sojntsuam pas nrig los nyem rau ntawm lub teeb lub cev hlau los yog ib feem ntawm cov conduction, yog hais tias tus high-voltage tshuab tsis tswb, qhia tias lub teeb high-voltage xeem dhau.
