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。7 V: l; N# F3 F
根据5.2.2章节有如下内容:2 o* ~ R+ T' _6 q5 c) N
Where, elsewhere in this standard, ROUTINE TESTS are required to be conducted in accordance
" E& I+ [. c$ ?+ q, q; x* Gwith 5.2.2, it is permitted to reduce the duration of the electric strength test to 1 s and to% ]$ U: ~2 \5 P) J& x
reduce the test voltage permitted in Table 5C, if used, by 10 %.
# A; H! \: w9 }! l# [, q" _% ]
2 |. ^0 w; f+ S) M" m* @& 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

O/ v( l7 o/ U& d' }– 3 000 V a.c. r.m.s. for REINFORCED INSULATION./ M# r* ?; y$ q
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。 |
