标题: 接地为什么可以帮助启动? [打印本页] 作者: aoxtck 时间: 2012-1-25 01:10 标题: 接地为什么可以帮助启动? “If earthing is provided to assist starting, or for EMC reasons, but is not connected to an accessible metal part, the luminaire may still be deemed to be of class II.”
这一条款为60598-1II类灯具定义部分的注三,讲的是接地为了帮助灯具启动,而不接到易触及金属部件,该灯具仍被认为II 类灯具。
