如题所示,关于IEC60950-1:2005中Routine Test 耐压测试时间与电压设定,我本人从标准中一直没看到有比较明确的说法。
( F" s. n1 Q& f \1 R% S+ h根据5.2.2章节有如下内容:. x& U h* @& c, U; y, E4 j

# } J, Y9 K G- u3 T这个内容说时间可以减少到1秒,电压可以根据表C来进行,但是说得很模糊,尤其是
: s Y* i: r& i) K' y1 g. k4 }Where, elsewhere 这两个单词,不好理解到底是哪里。是否也包括LN对地?我们产线上打的地方就是LN对地。: X/ R& [5 V% N7 ]& w8 O
, [5 G5 X& Q+ p& d& _还有在Annex U 中有如下内容:
3 Q8 c9 X' h! D( a) BU.3.1 Routine testing8 A8 ] \. R& B0 B! L$ ?

但是我一直觉得Annex U 只适用于Insulated winding wires for use without interleaved insulation,而不是用于我们产线上的位置(我们产线一般就打LN对地)。

希望各位可以引出标准进行讨论。 |
