EN60745.1-CLAUSE 21.11的理解

EN60745.1-CLAUSE 21.11如下:
Any assembley gag with a width greater 0.3mm in supplementary insulation shall not be coincidental with any such gap in basic insulation, neither shall any such gap in reinforced insulation give direct access to live parts.
附加绝缘中任何宽度大于0.3mm的装配间隙,不应与基本绝缘这类间隙重合;加强绝缘中这类间隙不应形成到带电体的直接通道。
那位朋友帮忙分析分析,谢谢 !
