大家好,有一个问题请大家帮忙一下,我在看IEC66053时,附加绝缘和加强绝缘一直分不清楚,哪位工程师能帮我举例解释一下,谢了!

请看标准中的定义:
supplementary insulation
independent insulation applied in addition to basic insulation in order to provide protection against electric shock in the event of failure of the basic insulation
[IEC 61140, definition 3.10.2, modified]

( E7 n- p; Y4 R+ l8 u3 `( @reinforced insulation
single insulation system applied to hazardous live parts, which provides a degree of protection against electric shock equivalent to double insulation
NOTE The term "insulation system" does not imply that the insulation is one homogeneous piece. It may comprise several layers which cannot be tested singly as supplementary or basic insulation.

楼上的能说说basic insulation和supplementary insulation的区别吗？

有意思的问题。除了从定义上区别和有限的相关试验上有区别外，两者本质和要求上还有什么区别？期望看到更多的意见。

附加绝缘是第二层绝缘，也就是说，附加绝缘里面还有一层是基本绝缘的，而加强绝缘则只有一层，加强绝缘里面就直接是带电部件了

请先看清楚附加绝缘的定义，其实定义已经说的比较清楚了！
