灯具driver61347要求
IEC61347中第十六章节由这么一句话:Lamp controlgear, where the components are so encapsulated in a self-hardening compound bonded to the relevant surfaces that no clearances exist, are not checked.是否可以理解为灌胶处理的driver就不再考虑电气间隙? 好像compound与surface是结合不住的 Nezof 发表于 2014-6-24 09:45 static/image/common/back.gif

那意思是要考虑爬电距离,电气间隙可以不考虑? ubuntufan 发表于 2014-6-24 09:53 static/image/common/back.gif

有缝隙的地方应该也有空气间隙吧,这个问题本版之前有讨论,可以搜搜看 楼主理解对头。 地板的理解才是正确的!
