8.2……………..主要说明只能碰到被带电体隔开的加强绝缘或双重绝缘。: r" f9 b$ \6 }( f
Note: (A2): buit-in appiance and fixed appliance are tested after install
/ F: U! W' f% M L+ M+ o5 M6 m- o/ P6 t/ B# E
再举个 delivered in separate units 的例子。 很多风扇都是你买来后自己装扇叶等一大堆东西。这个时候怎么可能满足加强绝缘?
]. C1 Z( a$ f1 q* IFixed appliance 的定义 (为什么说需要特殊的工具?)

可靠固定的附加要求可以参考一些分标准。如。-2-80, -2-30; f1 Q3 F6 a1 O" |* C) L* r4 r
太久没看忘记了,一般都在 note 里面举了一些例子说明怎么样才算可靠固定。 |
