标题: IEC60950中question 集锦 [打印本页] 作者: d60102224 时间: 2011-11-9 19:50 标题: IEC60950中question 集锦 question 1: 2.6.3中 Protection earthing conductors 和protective bonding conductors 分别指哪里?
谁有图片可以提供?尤其是protective bonding conductors.通常什么产品可见?作者: d60102224 时间: 2011-11-9 19:50
question 2: the voltage drop in a protective bonding conductor is measured after conducting the test current for the time period specified below. the test current can be either a.c. or d.c. and the test voltage shall not exceed 12V.
a) 针对保护电流为16A以下的产品,Protective bonding conductive 电阻不能超过0.1欧姆,是吗?
那上面的and the test voltage shall not exceed 12V适用于哪?看糊涂了!是测试电压，不是Protective bongding conductive的压降对吗？那么这个测试电压怎么施加呢？
b) 针对保护电流为16A以上的产品,voltage drop不能超过2.5V，是吗？作者: 04211 时间: 2011-11-9 19:51
要用高精準度萬用表!作者: fumsga 时间: 2011-11-9 19:51
Protection earthing conductors 接地线
protective bonding conductors 产品（机箱）内部的接地线或者用做接地的机壳作者: fumsga 时间: 2011-11-9 19:51
