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。
我想问,接地是怎么帮助灯具的启动的?有接地,却划分为II类,是不是II 类灯具可以用I 类器具的插头?
请哪位帮忙解释啊,江湖救急! 自己顶顶! EM...It's a good question. i did't think it before.
let's study on it .
