各位大神,请教一下:- n9 S* p7 j/ S6 A6 F4 @/ ]
- l9 ~; G B0 C! z; j IEC 60335-1 clause 5.14
( G9 A/ m4 I+ C
5 f6 P1 C* X0 B2 J: X5.14 If class 0I appliances or class I appliances have accessible metal parts that are not earthed and are not separated from live parts by an intermediate metal part that is earthed, such parts are checked for compliance with the appropriate requirements specified for class II construction.

这段如何理解:因为我们是配套家电产品做小电机的,这样这句话可否理解为我们电机(金属外壳,没有接地),需要按照class II construction.结构来处理,那就是需要加强绝缘或双重绝缘,那爬电距离空气间隙就要按照加强绝缘或双重绝缘来处理。
